Description

Technical Field

[0001] This application relates to the field of municipal underground pipelines, and particularly to a fully buried heat supply valve device. Background Art

[0002] The heat supply pipeline network is composed of multiple heat supply pipelines, which can send the heat sources generated by boiler rooms, direct-fired engine rooms or heat supply centers to the building heat supply inlets to meet the heating needs of residents.

[0003] In order to facilitate the control, detection or maintenance of each branch heat supply pipeline in the heat supply pipeline network, valve groups are usually set at intervals on the heat supply pipeline, and the valve groups can be used to connect or cut off the pipeline. The valve groups are generally installed in the heat well rooms, so that the staff can enter the heat well rooms to perform operations when they need to open or close part of the pipeline network.

[0004] The inventor found that on the one hand, in newly built residential communities in recent years, the thickness of the overlying soil layer above the garage roof generally fails to meet the design requirements of the heat well rooms; on the other hand, in the actual use process, rain and sewage intrude into the heat well rooms to form accumulated water. The long-term accumulated water in the heat well rooms will accelerate the aging of the valve devices in the well rooms, affect the use and increase the maintenance burden. At the same time, there are safety hazards in repairing or operating the valve devices in the enclosed space of the heat well rooms, and harmful gas accumulation and worker poisoning are likely to occur. Summary of the Invention

[0005] In order to extend the service life of the valve and improve the safety of valve-related operations, this application provides a fully buried heat supply valve device.

[0006] A fully buried heat supply valve device provided by this application adopts the following technical solutions:

[0007] A fully buried heat supply valve device includes:

[0008] A fully buried valve group, which includes a fully buried valve and a fully buried speed reduction mechanism connected to the fully buried valve, and the fully buried speed reduction mechanism is used to control the opening and closing of the fully buried valve;

[0009] A heat supply pipeline, and the fully buried valve is arranged on the heat supply pipeline.

[0010] By adopting the above technical solutions, the entire integrated fully buried heat supply valve device is directly buried in the soil, and there is no need to build a heat well room for this valve, so the problem of damage caused by the accumulated water in the heat well room soaking the valve will no longer occur, the service life is extended, and at the same time, the worker can operate this fully buried heat supply valve device on the ground, the ventilation environment is better, and the safety risk of underground confined space operations will not occur, reducing the operation risk.

[0011] Optionally, a hollow first vertical sleeve is provided at the top of the fully buried deceleration mechanism. An extension screw for connecting the input end of the fully buried deceleration mechanism is provided inside the first vertical sleeve, and the extension screw is used to drive the fully buried deceleration mechanism.

[0012] By adopting the above technical solution, the extension screw arranged at the input end of the fully buried deceleration mechanism is significantly different from the situation where the extension screw in the non-fully buried method is arranged at the output end of the deceleration mechanism. The extension screw drives the fully buried deceleration mechanism to operate, and the fully buried deceleration mechanism drives the fully buried valve to open. The first vertical sleeve is used to protect the extension screw and facilitate the operator to apply force to the extension screw.

[0013] Optionally, a fully buried exhaust and drain assembly is further included;

[0014] The fully buried exhaust and drain assembly includes a hollow second vertical sleeve, and the bottom of the second vertical sleeve is communicated with and arranged on the heating pipeline.

[0015] By adopting the above technical solution, when it is necessary to discharge the gas in the heating pipeline or drain the water in the heating pipeline, an external water pump or air pump pipeline is connected to the top of the second vertical sleeve to extract gas and / or drain water.

[0016] Optionally, a first displacement absorption assembly is further included, which includes a hollow first sleeve and a hollow second sleeve sleeved on its outer wall. The first sleeve and the second sleeve are slidably connected, and the first sleeve can extend out of the second sleeve;

[0017] The first sleeve of the first displacement absorption assembly is used to be sleeved outside the first vertical sleeve, and the two are arranged at intervals.

[0018] By adopting the above technical solution, when the heating pipeline where the fully buried heating valve device is installed undergoes axial deformation and displacement due to heat, soft substances can be filled in the interval between the first sleeve and the first vertical sleeve, thereby pre-forming a preset displacement compensation. The first vertical sleeve can move horizontally synchronously, thereby reducing the stress damage of the lateral soil reaction force on structural components such as the first vertical sleeve during translation. Of course, soft substances can also not be filled, and the interval itself can also be a kind of displacement compensation.

[0019] Optionally, a first displacement absorption assembly is further included, which includes a hollow first sleeve and a hollow second sleeve sleeved on its outer wall. The first sleeve and the second sleeve are slidably connected, and the first sleeve can extend out of the second sleeve;

[0020] The first sleeve of the first displacement absorption assembly is used to be sleeved outside the second vertical sleeve, and the two are arranged at intervals.

[0021] By adopting the above technical solution, when the heat supply pipeline is heated and undergoes axial deformation and displacement, soft substances can be filled in the interval between the first sleeve and the second vertical sleeve, thereby pre-forming a preset displacement compensation. The fully buried exhaust and drainage assembly can move horizontally synchronously, thereby reducing the stress damage of the lateral soil reaction force during translation to the fully buried exhaust and drainage assembly. Of course, soft substances can also not be filled, and the interval itself can also be a kind of displacement compensation.

[0022] Optionally, it further includes a second displacement absorption assembly, which includes a hollow third sleeve and a hollow fourth sleeve sleeved on its outer wall, and the two are arranged at intervals.

[0023] The third sleeve of the second displacement absorption assembly is used to be sleeved outside the first vertical sleeve, and the bottom end of the third sleeve abuts against the outer wall of the first vertical sleeve.

[0024] By adopting the above technical solution, when the heat supply pipeline is heated and undergoes axial deformation and displacement, soft substances can be filled in the position between the fourth sleeve and the third sleeve, thereby pre-forming a preset displacement compensation. The first vertical sleeve can move horizontally synchronously, thereby reducing the stress damage of the lateral soil reaction force during translation to structural members such as the first vertical sleeve. Of course, soft substances can also not be filled, and the interval itself can also be a kind of displacement compensation.

[0025] Optionally, it further includes a second displacement absorption assembly, which includes a hollow third sleeve and a hollow fourth sleeve sleeved on its outer wall, and the two are arranged at intervals.

[0026] The third sleeve of the second displacement absorption assembly is used to be sleeved outside the second vertical sleeve, and the bottom end of the third sleeve abuts against the outer wall of the second vertical sleeve.

[0027] By adopting the above technical solution, when the heat supply pipeline is heated and undergoes axial deformation and displacement, soft substances can be filled in the position between the fourth sleeve and the third sleeve, thereby pre-forming a preset displacement compensation. The fully buried exhaust and drainage assembly can move horizontally synchronously, thereby reducing the damage of the horizontal lateral soil reaction force to the fully buried exhaust and drainage assembly. Of course, soft substances can also not be filled, and the interval itself can also be a kind of displacement compensation.

[0028] Optionally, the first vertical sleeve includes an upper first vertical sleeve and a lower first vertical sleeve that is spherically hinged to it, and the lower first vertical sleeve is arranged on the top of the fully buried deceleration mechanism;

[0029] And / or the first vertical sleeve includes an upper first vertical sleeve, a lower first vertical sleeve, and a corrugated pipe or a rubber pipe connected between the two.

[0030] By adopting the above technical solution, when the heat supply pipeline is heated and undergoes axial deformation and displacement, the lower first vertical sleeve is driven to move together, and the upper first vertical sleeve can tilt and swing relative to the lower first vertical sleeve. The tilt and swing of the upper first vertical sleeve is equivalent to the inelastic deformation of the cantilever of the cantilever mechanism, absorbing the torsional stress and shear stress acting on the cantilever at the fixed end of the cantilever. Therefore, this design greatly reduces the stress damage and destruction of the soil horizontal lateral reaction force on structures such as the upper first vertical sleeve and the lower first vertical sleeve, thus ensuring that the fully directly buried heat supply valve device can work safely and reliably in the soil. The corrugated pipe or rubber pipe can also form a preset displacement compensation and also a preset stress compensation.

[0031] Optionally, the second vertical sleeve includes an upper second vertical sleeve and a lower second vertical sleeve ball-jointed thereto. The bottom of the lower second vertical sleeve is communicated with and arranged on the heat supply pipeline;

[0032] And / or the second vertical sleeve includes an upper second vertical sleeve, a lower second vertical sleeve, and a corrugated pipe or a rubber pipe connected between the two.

[0033] By adopting the above technical solution, when the heat supply pipeline is heated and undergoes axial deformation and displacement, the lower second vertical sleeve is driven to move together, and the upper second vertical sleeve can tilt and swing relative to the lower second vertical sleeve. The tilt and swing of the upper second vertical sleeve is equivalent to the inelastic deformation of the cantilever of the cantilever mechanism, absorbing the torsional stress and shear stress acting on the cantilever at the fixed end of the cantilever. Therefore, this design greatly reduces the stress damage and destruction of the soil horizontal lateral reaction force on structures such as the upper second vertical sleeve and the lower second vertical sleeve, thus ensuring that the fully directly buried exhaust and drainage assembly can work safely and reliably in the soil; the corrugated pipe or rubber pipe can also form a preset displacement compensation and also a preset stress compensation.

[0034] Optionally, a frame one is arranged at the top of the first sleeve, and a lid one is arranged on the frame one.

[0035] By adopting the above technical solution, the lid one can cover the top of the first sleeve. If the first sleeve is filled with soft substances inside, when the lid one is opened, the soft substances can be seen, and the lid one will not move together with the first vertical sleeve or the fully directly buried exhaust and drainage assembly.

[0036] Optionally, a lid two is arranged at the top of the third sleeve. The lid two is connected to a frame two located at the top of the fourth sleeve through a plurality of rings that can partially overlap and have diameters increasing from inside to outside;

[0037] At least one anti-rotation plate is arranged on the outer wall of the third sleeve.

[0038] By adopting the above technical solution, cover 2 can move with the third sleeve. If the gap is filled with soft materials, the soft materials cannot be seen when cover 2 is opened; when the third sleeve does not move, the edge of cover 2 is placed on the ring with the smallest diameter. Since multiple stacked rings are provided, when the third sleeve moves, the rings are displaced to a certain extent, so that no gap will appear on the top of the fourth sleeve; when the gap is filled, the anti-rotation plate can increase the friction between the first vertical sleeve and the soft material and reduce the occurrence of rotation.

[0039] Optionally, it also includes an opening indication assembly, which includes a guide rod arranged on the inner wall of the first vertical sleeve and a first elastic member and an opening indication block sequentially sleeved on the extension screw from bottom to top, the opening indication block is threadedly connected to the extension screw and is slidingly connected to the guide rod, and the top of the extension screw is used to detachably clamp an opening valve stem.

[0040] By adopting the above technical scheme, when it is necessary to close the fully direct buried valve, the valve stem is rotated to open, thereby driving the extension screw to rotate, and the extension screw in turn drives the fully direct buried reduction mechanism to operate, and the fully direct buried reduction mechanism drives the fully direct buried valve to open; in the process of rotating the valve stem, the opening indicator block will move downward along the extension screw and compress the first elastic member. If the elastic potential energy accumulated in the first elastic member is sufficient to bounce the extension screw and the valve stem, once the operator removes the external force, the extension screw and the valve stem will be bounced up, indicating that the fully direct buried valve has been closed, which will reduce the damage caused by excessive rotation of the fully direct buried reduction mechanism.

[0041] Optionally, a second elastic member is sleeved on the extension screw rod on the side of the opening indicating block facing away from the first elastic member, and an abutment body is horizontally extended from one end of the valve opening rod that is detachably engaged with the extension screw rod.

[0042] By adopting the above technical solution, when it is necessary to open the fully direct buried valve, the valve stem is rotated in the opposite direction, and the opening indicator block will move upward along the extended screw to compress the second elastic member. If the elastic potential energy accumulated in the second elastic member is sufficient to bounce the valve stem, once the operator removes the external force, the valve stem will be bounced up, indicating that the fully direct buried valve has been opened, which will reduce the damage caused by excessive rotation of the fully direct buried deceleration mechanism.

[0043] Optionally, a flange assembly is also included; the flange assembly includes a first flange sleeved on the top of the second vertical sleeve and a second flange detachably connected to the first flange, and an air passage is provided on the second flange.

[0044] By adopting the above technical solution, when it is necessary to discharge the gas in the heating pipe, the air duct can be opened to implement the exhaust; when it is necessary to drain the heating pipe, in order to meet the demand for drainage of a large space, the second flange can be unscrewed, and the second vertical sleeve and the external water pump pipe can be connected through the first flange to implement the drainage operation.

[0045] Optionally, the fully buried exhaust and drainage assembly also includes a hollow, shrinkable antifreeze core located in the second vertical sleeve, and a gap is formed between the inner wall of the second vertical sleeve and the outer wall of the antifreeze core, one end of the gap is connected to the heating pipe, and the other end is connected to the airway.

[0046] By adopting the above technical solution, when the water in the gap between the inner wall of the second vertical sleeve and the outer wall of the antifreeze core freezes, it will be squeezed toward the antifreeze core, reducing the possibility of squeezing toward the second vertical sleeve, thereby protecting the second vertical sleeve;

[0047] When the heating pipe needs to be drained, in order to meet the demand for large-flow drainage, the antifreeze core can be pulled out, and the first flange and the external water pump pipeline can be connected or the pumping pipeline of the external water pump can be inserted from the first flange; when exhaust is required, the gas can be discharged through the gap.

[0048] Optionally, it also includes an automatic sealing male head for sealing the airway, which includes a male head seat arranged on the side of the second flange away from the first flange, a special-shaped channel is opened on the male head seat, one end of the special-shaped channel is connected to the airway, a third elastic member is arranged on the middle airway wall of the special-shaped channel, the other end of the special-shaped channel gradually narrows in the direction away from the airway, and a conical block is arranged on the end of the third elastic member away from the airway, and the conical block is used to seal the other end of the special-shaped channel.

[0049] By adopting the above technical solution, when the gas in the heating pipe needs to be discharged, the conical block can be pressed to implement exhaust, the external force on the conical block is removed, and the conical block is reset and blocks the airway under the action of the third elastic member; when drainage is required, the first flange and the automatic sealing male head can be removed together.

[0050] Optionally, a protective shell is provided on the upper cover of the full direct-buried speed reduction mechanism.

[0051] By adopting the above technical solution, the outer surface of the full direct buried reduction mechanism is further protected, thereby reducing the corrosion of the full direct buried reduction mechanism by water and other chemical substances in the environment.

[0052] Optionally, the protective shell is provided with an opening for injecting a sealing medium, and the sealing medium is used to form a waterproof layer outside the full direct-buried speed reduction mechanism.

[0053] By adopting the above technical solution, the waterproof layer wraps the speed reduction mechanism for full direct burial, further reducing the damage caused by water and other chemical substances to the speed reduction mechanism for full direct burial.

[0054] In summary, the present application includes at least one of the following beneficial technical effects:

[0055] 1. The entire device is directly buried in the soil, without excessive accumulation of water in a local area, reducing the damage to the entire device caused by excessive water accumulation and extending their service life;

[0056] 2. When the heat supply pipeline of the present full direct burial heat supply valve device is heated and undergoes axial deformation and displacement, soft substances can be filled in the interval, thereby pre-forming a preset displacement compensation, which is also a preset stress compensation. Structural components such as the opening indication component or the full direct burial exhaust and drainage component can move horizontally synchronously, thereby reducing the stress damage and destruction to the structure caused by the lateral soil reaction force during translation, making the direct burial structure more reliable and capable of long-term operation; of course, soft substances can also not be filled, and the interval itself can also be a displacement compensation;

[0057] 3. When the heat supply pipeline is heated and undergoes axial deformation and displacement, the upper first vertical sleeve or the upper second vertical sleeve can tilt and swing. The tilting and swinging is equivalent to the inelastic deformation of the cantilever of the cantilever mechanism, absorbing the torsional stress and shear stress acting on the fixed end of the cantilever by the external force on the cantilever. Therefore, this design greatly reduces the stress damage and destruction to the structure caused by the horizontal lateral soil reaction force, thus ensuring that the structure can work safely, reliably and for a long time in the soil;

[0058] 4. The opening indication component can indicate whether the valve for full direct burial is opened or closed, reducing the damage to the speed reduction mechanism for full direct burial caused by excessive operation of the valve stem and extending the service life of the valve group for full direct burial.

[0082] The following further elaborates on this application Figures 1-11 in conjunction with the appended drawings.

[0083] An embodiment of this application discloses a fully buried heat supply valve device.

[0084] Embodiment 1

[0085] Referring to Figure 1 and Figure 2 , a fully buried heat supply valve device includes a horizontally arranged heat supply pipeline 20 and a fully buried valve group 10 arranged on the heat supply pipeline 20. Both are used for being directly buried underground, and when buried underground, excessive water accumulation will not occur locally. The accumulated water contacted by the entire device is a small amount of accumulated water existing in the environment, thereby being able to extend the service life of the entire device.

[0086] The fully buried valve group 10 includes a fully buried valve 11 for controlling the on / off of the heat supply pipeline 20 and a fully buried speed reduction mechanism 12 connected to the fully buried valve 11. The fully buried speed reduction mechanism 12 is used to control the opening and closing of the fully buried valve 11. By setting the fully buried speed reduction mechanism 12, an operator can open the fully buried valve 11 with a relatively small force.

[0087] Since the heat supply pipeline 20 and the fully buried valve group 10 are directly buried underground, in order to reduce the damage to the fully buried speed reduction mechanism 12 caused by water and other chemical substances in the environment, a protective shell 100 is also provided over the fully buried speed reduction mechanism 12.

[0088] Among them, the fully buried speed reduction mechanism 12 can be a speed reducer, that is, a protective shell 100 is added to the speed reducer. In addition, the fully buried speed reduction mechanism 12 and the protective shell 100 can jointly form a speed reducer with a self - contained protective shell 100.

[0089] In order to enhance the protection of the fully buried speed reduction mechanism 12, the protective shell 100 is provided with an opening 101 for injecting a sealing medium. The sealing medium is used to form a waterproof layer on the fully buried speed reduction mechanism 12 to further reduce the corrosion caused by water and other chemical substances to the fully buried speed reduction mechanism 12. Specifically, the sealing medium is grease, gel or paraffin, etc.

[0090] Referring to Figure 2 and Figure 3 , a fully buried heating valve device includes a hollow first vertical sleeve 31 arranged on the top of a protective shell 100, an extension screw 32, and an opening degree indicating assembly 30 for indicating the opening degree of a fully buried valve 11.

[0091] The extension screw 32 is located in the lower part inside the first vertical sleeve 31 and its top does not protrude from the first vertical sleeve 31. The bottom of the first vertical sleeve 31 is fixedly connected to the protective shell 100, and the bottom of the extension screw 32 is connected to the input end of a fully buried speed reduction mechanism 12 for driving the switch of the fully buried speed reduction mechanism 12.

[0092] In addition to being arranged on the protective shell 100, the first vertical sleeve 31 can also be directly arranged on the top of the fully buried speed reduction mechanism 12.

[0093] The opening degree indicating assembly 30 includes a guide rod 33 arranged on the inner wall of the first vertical sleeve 31, and a first elastic member 34, an opening degree indicating block 35, and a second elastic member 37 sleeved on the extension screw 32 from bottom to top. The opening degree indicating block 35 is threadedly connected to the extension screw 32 and is also slidably connected to the guide rod 33. The opening degree indicating block 35 can keep the extension screw 32 vertical, and the guide rod 33 guides the opening degree indicating block 35. Both the first elastic member 34 and the second elastic member 37 are springs.

[0094] The top of the extension screw 32 is used for detachably clamping an open valve rod 36. Specifically, the end of the open valve rod 36 for clamping with the extension screw 32 can be provided with a hexagonal groove, and the top of the extension screw 32 is arranged as a hexagonal prism column adapted to the hexagonal groove. A contact body 361 horizontally extends on the hexagonal groove for contacting the second elastic member 37.

[0095] When it is necessary to close the fully buried valve 11, rotate the open valve rod 36, which drives the extension screw 32 to rotate. The extension screw 32 drives the fully buried speed reduction mechanism 12 to operate. The fully buried speed reduction mechanism 12 converts small torque into large torque to drive the fully buried valve 11 to open. During the process of rotating the open valve rod 36, the opening degree indicating block 35 will move downward along the extension screw 32 and compress the first elastic member 34. If the elastic potential energy accumulated by the first elastic member 34 is sufficient to bounce up the extension screw 32 and the open valve rod 36, at the moment when the operator releases the hand, the extension screw 32 and the open valve rod 36 will be bounced up, indicating that the fully buried valve 11 has been closed.

[0096] When it is necessary to open the fully buried valve 11, rotate the valve opening rod 36 in the reverse direction. The opening degree indicating block 35 will move upward along the extension screw rod 32 and compress the second elastic member 37. The second elastic member 37 presses against the abutting body 361. If the elastic potential energy accumulated by the second elastic member 37 is sufficient to bounce up the valve opening rod 36, at the moment when the operator releases the hand, the valve opening rod 36 will be bounced up, indicating that the fully buried valve 11 has been opened.

[0097] For the convenience of applying force, a hole can be opened at one end of the valve opening rod 36 away from the abutting body 361. The hole is used to connect the force-applying tool, the screwdriver 1, and the valve opening rod 36 is rotated by rotating the screwdriver 1.

[0098] For the convenience of storing the valve opening rod 36, a long hole 321 can be arranged in the length direction of the extension screw rod 32. When the valve opening rod 36 is not needed, it is inserted into the long hole 321. Even if the length of the long hole 321 is greater than the length of the valve opening rod 36, due to the existence of the abutting body 361, the valve opening rod 36 will not completely fall into the long hole 321.

[0099] Refer to Figure 2 、 Figure 4 and Figure 5 and, a fully buried heating valve device further includes a fully buried exhaust and drain assembly 40, a flange assembly 50, and an automatic sealing male head 60.

[0100] The fully buried exhaust and drain assembly 40 includes a hollow second vertical sleeve 41 and a hollow antifreeze core 42 located inside the second vertical sleeve 41. The bottom of the second vertical sleeve 41 communicates with the heating pipeline 20 and is fixedly connected to the heating pipeline 20. A gap is formed between the inner wall of the second vertical sleeve 41 and the outer wall of the antifreeze core 42. The top of the antifreeze core 42 is lower than the top of the second vertical sleeve 41. The antifreeze core 42 is freely arranged and can float under the action of gas or water in the heating pipeline 20. Therefore, the bottom of the antifreeze core 42 is higher than the bottom of the second vertical sleeve 41.

[0101] Among them, the material of the antifreeze core 42 is selected as a rubber material with a shrinkage rate greater than the expansion rate of ice. When the water in the gap between the inner wall of the second vertical sleeve 41 and the outer wall of the antifreeze core 42 freezes, it will be squeezed toward the antifreeze core 42 side, reducing the extrusion on the second vertical sleeve 41, thereby protecting the second vertical sleeve 41. In order to reduce the formation of ice inside the antifreeze core 42, antifreeze oil can be injected into it.

[0102] The flange assembly 50 includes a first flange 51 sleeved on the top of the second vertical sleeve 41 and a second flange 52 detachably connected to the first flange 51. An air passage 521 is opened on the second flange 52.

[0103] The automatic sealing male head 60 includes a male head seat 61 disposed on the side of the second flange 52 away from the first flange 51. An irregular-shaped channel 611 is formed on the male head seat 61. One end of the irregular-shaped channel 611 communicates with the air duct 521. A third elastic member 62 is provided on the air duct wall in the middle of the irregular-shaped channel 611. The other end of the irregular-shaped channel 611 gradually narrows in a direction away from the air duct 521 and forms a tapered hole. A tapered block 63 is provided at one end of the third elastic member 62 facing away from the air duct 521, and the tapered block 63 is used to block the tapered hole. Among them, the third elastic member 62 is a spring.

[0104] When it is necessary to discharge the gas in the heating pipeline 20, press the tapered block 63, and the other end of the irregular-shaped channel 611 is opened, and the exhaust can be implemented; when the external force on the tapered block 63 is withdrawn, the tapered block 63 can block the air duct 521 under the action of the third elastic member 62.

[0105] For the convenience of maintenance, it is necessary to first drain the heating pipeline 20. The second flange 52 can be unscrewed, and the antifreeze core 42 can be taken out. Then, the first flange 51 can be connected to the external water pump pipeline to implement the drainage operation.

[0106] Refer to Figure 5 and Figure 6 To save manual operation and improve the inconvenience caused by continuously pressing the tapered block 63, an automatic sealing female head 90 that cooperates with the automatic sealing male head 60 is provided. It includes a female head seat 91 and a slot 92 that is formed on the female head seat 91 along the length direction of the female head seat 91 and is adapted to the shape of the male head seat 61.

[0107] An exhaust channel 911 is further formed on the female head seat 91 opposite to the slot opening of the slot 92. One end of the exhaust channel 911 faces the tapered block 63 and gradually expands in a direction away from the tapered block 63, and forms a tapered opening. A fourth elastic member 93 is provided on the air duct wall in the middle of the exhaust channel 911. The other end of the exhaust channel 911 communicates with the outside. A conical body 94 is provided at one end of the fourth elastic member 93 facing the tapered block 63, and it is used to block the tapered opening. Among them, the fourth elastic member 93 is a spring.

[0108] When the male head seat 61 is inserted into the slot 92, under the interaction of the tapered block 63 and the conical body 94, the irregular-shaped channel 611 and the exhaust channel 911 are opened and communicated. At the same time, an elastic clamping block 921 is provided on the slot wall of the slot 92, and a clamping groove 612 is correspondingly provided on the outer wall of the male head seat 61. The clamping block 921 is embedded in the clamping groove 612 to fix the male head seat 61 and the female head seat 91 together, so that the exhaust can be realized without continuously pressing the tapered block 63 with external force.

[0109] Refer to Figure 2 、 Figure 3 and Figure 4, since during the heating process of the heat, the water flowing through the heat supply pipeline 20 will cause horizontal movement of the heat supply pipeline 20, the fully buried valve group 10, the opening degree indicating component 30, and the fully buried exhaust and drain component 40. Therefore, a first displacement absorption component 70 is provided outside both the first vertical sleeve 31 and the second vertical sleeve 41.

[0110] The first displacement absorption component 70 includes a hollow first sleeve 71 and a hollow second sleeve 72 sleeved thereon. The first sleeve 71 and the second sleeve 72 are slidably connected, and the slidable connection can reduce the damage to the fully buried valve group 10 or the heat supply pipeline 20 caused by the road surface subsidence. When the first displacement absorption component 70 is buried underground, in order to adapt to the height of the ground, the first sleeve 71 can extend out of the second sleeve 72, so that the first sleeve 71 is flush with the ground.

[0111] The first sleeve 71 of a first displacement absorption component 70 is used to be sleeved outside the first vertical sleeve 31, and there is a gap between the two, so that there is a gap between the second sleeve 72 and the first vertical sleeve 31. The gap therebetween is used to fill a soft material 2, such as sandy soil, etc. The soft material 2 can fill the entire height of the second sleeve 72, or only fill part of the first sleeve 71 and below it. This can avoid the interference of the soft material 2 and facilitate the operation of the opening degree indicating component 30. After the first vertical sleeve 31 and the first sleeve 71 are buried underground, the height of the first sleeve 71 is higher than that of the first vertical sleeve 31. A frame one is provided at the top of the first sleeve 71, and a cover one 711 is provided on the frame one (see Figure 4 ). By opening the cover one 711, the soft material 2 can be seen. The cover one 711 will not move together with the opening degree indicating component 30. The bottom of the second sleeve 72 is sealed by a rubber ring to reduce the entry of the soft material 2 into the first vertical sleeve 31.

[0112] When the heat supply pipeline 20 is heated and undergoes axial deformation and displacement, a preset displacement compensation, which is also a preset stress compensation, is pre-formed by the soft material 2 filled in the gap between the first sleeve 71 and the first vertical sleeve 31. The first vertical sleeve 31 can move horizontally synchronously, reducing the damage to the opening degree indicating component 30 caused by the lateral soil reaction force during translation.

[0113] The first sleeve 71 of another first displacement absorption assembly 70 is used to be sleeved outside the second vertical sleeve 41, and the two are arranged at intervals, so that the second sleeve 72 and the second vertical sleeve 41 are arranged at intervals, wherein the interval between the two is used to fill soft material 2, such as sand, etc. The soft material 2 can fill the entire height of the second sleeve 72, or only fill part of the first sleeve 71 and the bottom thereof, so as to avoid the obstruction of the soft material 2 and facilitate the operation of the fully buried exhaust and drainage assembly 40. After the second vertical sleeve 41 and the first sleeve 71 are buried underground, the height of the first sleeve 71 is higher than the height of the second vertical sleeve 41, and another frame 1 is also provided on the top of the first sleeve 71, and a cover 1 711 is provided on the frame 1. The soft material 2 can be seen by opening the cover 1 711, and the cover 1 711 will not move with the fully buried exhaust and drainage assembly 40. The bottom of the second sleeve 72 is sealed by a rubber ring to reduce the soft material 2 from entering the second vertical sleeve 41.

[0114] When the heating pipe 20 is heated and axially deformed and displaced, the soft material 2 filled in the gap between the first sleeve 71 and the second vertical sleeve 41 pre-forms a preset displacement compensation, which is also a preset stress compensation. The second vertical sleeve 41 can move horizontally synchronously to reduce the damage of the lateral reaction force of the soil to the fully buried exhaust and drainage assembly 40 during translation. Of course, the soft material 2 can also be not filled, and the gap itself can also be a displacement compensation. In order to reduce the possibility of the soft material 2 entering the second vertical sleeve 41, its top can be blocked.

[0115] Embodiment 2

[0116] Reference Figure 7 , Figure 8 and Figure 9 The difference between the second embodiment and the first embodiment is that the second embodiment uses a second displacement absorption assembly 80 to replace the first displacement absorption assembly 70 in the first embodiment, and a support frame 4 is added to support the heating pipe 20.

[0117] The second displacement absorbing component 80 includes a third sleeve 81 and a fourth sleeve 82 made of PVC material mounted thereon, both of which are hollow. At least one anti-rotation plate 811 is arranged on the outer wall of the third sleeve 81. The anti-rotation plate 811 is spaced apart from the inner wall of the fourth sleeve 82 on the side facing away from the third sleeve 81. The outer wall of the third sleeve 81 where the anti-rotation plate 811 is not arranged is also spaced apart from the inner wall of the fourth sleeve 82.

[0118] The third sleeve 81 of a second displacement absorption component 80 is used to sleeved on the upper part of the first vertical sleeve 31. The bottom of the third sleeve 81 is frictionally connected to the outer wall of the first vertical sleeve 31 through a sealing ring, which is conducive to the settlement of the third sleeve 81 with the road surface, reducing the force transmission to the fully buried valve group 10 and reducing the service life of the fully buried valve group 10. The fourth sleeve 82 made of PVC material will settle with the road surface, and the selection of PVC material will not damage the fully buried valve group 10.

[0119] An interval is also formed between the fourth sleeve 82 and the part of the first vertical sleeve 31 where the third sleeve 81 is not sleeved.

[0120] A second lid 812 is provided at the top of the third sleeve 81 (see Figure 9 ), and the second lid 812 is connected to a second frame located at the top of the fourth sleeve 82 through a plurality of rings 3 that can partially overlap and have diameters increasing from the inside to the outside. The ring 3 with the largest diameter is placed on the second frame, and the second lid 812 is arranged on the ring 3 with the smallest diameter.

[0121] The second lid 812 can move together with the third sleeve 81. When the second lid 812 is opened, the soft material 2 cannot be seen. The bottom of the fourth sleeve 82 is sealed by a rubber ring to reduce the entry of the soft material 2 into the first vertical sleeve 31.

[0122] When the third sleeve 81 does not move, the edge of the second lid 812 is placed on the ring 3 with the smallest diameter. However, due to the arrangement of a plurality of stacked rings 3, when the third sleeve 81 moves, a certain dislocation of the rings 3 can prevent gaps from appearing at the top of the fourth sleeve 82.

[0123] To adapt to the height of the ground, when the fourth sleeve 82 is just buried underground, its top can be higher than the ground, and then the protruding part can be cut off according to the situation, so there is no need to set an extended sleeve. Without changing the structure of the first vertical sleeve 31, in the second embodiment, a third sleeve 81 with an anti-rotation plate 811 is added, which can increase the friction between the first vertical sleeve 31 and the soft material 2 and reduce the occurrence of rotation when filling the interval.

[0124] When the heating pipeline 20 is heated and undergoes axial deformation and displacement, the intervals between the fourth sleeve 82 and the third sleeve 81 and between the fourth sleeve 82 and the first vertical sleeve 31 are filled with the soft material 2. The specific filling method can refer to the method in the first embodiment. This can avoid the interference of the soft material 2, facilitate the operation of the opening degree indicating component 30, and thus form a preset displacement compensation in advance, which is also a preset stress compensation. The first vertical sleeve 31 can move horizontally synchronously.

[0125] The fourth sleeve 82 of another second displacement absorption component 80 is used to sleeved outside the second vertical sleeve 41, and the bottom of the third sleeve 81 is frictionally connected to the outer wall of the second vertical sleeve 41 through a sealing ring, which is conducive to the third sleeve 81 settling with the road surface, reducing the force transmitted to the heating pipeline 20 and reducing the service life of the heating pipeline 20. There is also a gap between the fourth sleeve 82 and the part of the second vertical sleeve 41 where the third sleeve 81 is not sleeved. Among them Figure 9 The automatic sealing male head 60 is hidden in the air duct 521 on the second flange 52.

[0126] A cover two 812 is also provided at the top of the third sleeve 81 of another second displacement absorption component 80. The specific setting form is the same as the situation where the cover two 812 is provided on the third sleeve 81 of the foregoing first second displacement absorption component 80, and will not be elaborated here.

[0127] Of course, in order to avoid the fourth sleeve 82 being set too long, a telescopic sleeve 5 can also be provided at the lower part. The telescopic sleeve 5 is sleeved on the second vertical sleeve 41. The two do not contact and soft material 2 is also used to fill between them. The specific filling method can refer to the method in Embodiment 1. This can avoid the obstruction of the soft material 2 and facilitate the operation of the fully buried exhaust and drainage component 40. The lower part of the fourth sleeve 82 is sleeved on the upper part of the telescopic sleeve 5, and the bottom of the telescopic sleeve 5 is sealed by a rubber ring to reduce the entry of the soft material 2 into the second vertical sleeve 41.

[0128] In order to adapt to the height of the ground, when the fourth sleeve 82 is just buried underground, its top can be higher than the ground, and then the protruding part can be cut according to the situation, so there is no need to set an extension sleeve. Without changing the structure of the second vertical sleeve 41, a third sleeve 81 with an anti-rotation plate 811 is added in Embodiment 2. When filling the gap, the friction between the second vertical sleeve 41 and the soft material 2 can be increased to reduce the occurrence of rotation.

[0129] When the heating pipeline 20 is heated and undergoes axial deformation and displacement, the gaps between the fourth sleeve 82 and the third sleeve 81, between the fourth sleeve 82 and the second vertical sleeve 41, and between the telescopic sleeve 5 and the second vertical sleeve 41 are all filled with the soft material 2. The specific filling method can refer to the method in Embodiment 1. Thus, a preset displacement compensation is pre-formed, and it is also a preset stress compensation. The second vertical sleeve 41 can move horizontally synchronously.

[0130] Embodiment 3

[0131] Refer to Figure 10, in order to reduce the damage caused to the opening indication assembly 30 when the heating pipeline 20 is heated and undergoes axial deformation and displacement, in addition to the above-mentioned method of setting the displacement absorption assembly to form a preset displacement compensation, the method of spherical hinge connection can also be used to form a preset displacement compensation.

[0132] Specifically: The first vertical sleeve 31 includes an upper first vertical sleeve 311 and a lower first vertical sleeve 312 that is spherically hinged to it. The lower first vertical sleeve 312 is arranged at the top of the protective shell 100 or passes through the protective shell 100 and is arranged on the fully buried deceleration mechanism 12. The proportion of the lower first vertical sleeve 312 in the entire first vertical sleeve 31 is very small and can be only the end part.

[0133] When the heating pipeline 20 is heated and undergoes axial deformation and displacement, the lower first vertical sleeve 312 is driven to move together, and the upper first vertical sleeve 311 can tilt and swing relative to the lower first vertical sleeve 312. The tilt and swing of the upper first vertical sleeve 311 is equivalent to the inelastic deformation of the cantilever of the cantilever mechanism, absorbing the torsional stress and shear stress acting on the fixed end of the cantilever by the external force on the cantilever. Therefore, this design greatly reduces the stress damage and destruction of structures such as the upper first vertical sleeve 311 and the lower first vertical sleeve 312 caused by the horizontal lateral reaction force of the soil, thus ensuring that this fully buried heating valve device can work safely and reliably in the soil.

[0134] Refer to Figure 11 , in order to reduce the damage caused to the fully buried exhaust and drain assembly 40 when the heating pipeline 20 is heated and undergoes axial deformation and displacement, in addition to the above-mentioned method of setting the displacement absorption assembly to form a preset displacement compensation, the method of spherical hinge connection can also be used to form a preset displacement compensation.

[0135] Specifically: The second vertical sleeve 41 includes an upper second vertical sleeve 411 and a lower second vertical sleeve 412 that is spherically hinged to it. The bottom of the lower second vertical sleeve 412 is connected and arranged on the heating pipeline 20. The proportion of the lower second vertical sleeve 412 in the entire second vertical sleeve 41 is very small and can be only the end part.

[0136] When the heat supply pipeline 20 is heated and undergoes axial deformation and displacement, the lower second vertical sleeve 412 is driven to move together, and the upper second vertical sleeve 411 can tilt and swing relative to the lower second vertical sleeve 412. The tilt and swing of the upper second vertical sleeve 411 is equivalent to the inelastic deformation of the cantilever of the cantilever mechanism, absorbing the torsional stress and shear stress acting on the fixed end of the cantilever by the external force on the cantilever. Therefore, this design greatly reduces the stress damage and failure of structures such as the upper second vertical sleeve 411 and the lower second vertical sleeve 412 caused by the horizontal lateral reaction force of the soil, thus ensuring that the fully directly buried heat supply valve device can work safely and reliably in the soil.

[0137] In addition to the above-mentioned spherical hinge connection method, the upper second vertical sleeve 411 and the lower second vertical sleeve 412 can also be connected by a bellows or a rubber tube to form a preset displacement compensation.

[0138] The above are all the preferred embodiments of this application. Without restricting the protection scope of this application accordingly, therefore: All equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
