Description

Technical Field

[0001] The invention relates to the technical field of valve production, in particular to an adaptive buried butterfly valve and a processing device thereof. Background Art

[0002] In the urban water supply network, underground laying of pipelines and underground installation of butterfly valves are a common installation type, which saves urban space, beautifies urban layout, saves construction and maintenance costs, and provides protection for residents' water use. The butterfly valve is a valve that uses a disc-type opening and closing member to reciprocate by about 90 degrees to open, close or adjust the flow of the medium. The butterfly valve is not only simple in structure, small in size, light in weight, saves material consumption, small in installation size, small in driving torque, easy and quick to operate, but also has good flow regulation function and closing and sealing characteristics at the same time. The butterfly valve is widely used; However, during the years of use and operation, many problems have been exposed and need to be solved urgently: 1. Since the manhole cover has no anti-theft components, it is easy to lose the manhole cover, which can easily cause a series of safety accidents and endanger the safety of people's travel; 2. Since the valve box is usually a fixed design, it cannot adapt to the settlement and height changes of the road hardening layer, resulting in the valve box often protruding or concave on the road surface, causing travel problems; 3. Usually the valve is installed in the valve well, which has the problems of large space occupation, long construction period and high construction cost. At the same time, the water in the valve well is easy to submerge the valve, and the accumulated water and soil will corrode the valve for a long time, which is easy to cause the valve transmission system to rust; 4. Unable to intuitively judge the valve switch status; 5. The valve is directly affected by the ground pressure, which is prone to valve deformation. In addition, the valve needs to be opened again to switch it when the valve is buried directly underground, which is very costly. Summary of the invention

In addition, the technical solutions and technical features between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0019] The present invention provides the following embodiments Example 1 The embodiment of the present invention provides an adaptive buried butterfly valve, such as Figure 1-5 As shown, it includes a turbine reduction box 1, which is bolted to one side of the main valve body 5, a switch assembly 2 is provided on one side of the turbine reduction box 1, a valve box assembly 4 is provided above the switch assembly 2, a valve position opening wheel 36 is provided in the switch assembly 2, and the valve position opening wheel 36 is used to synchronously indicate the opening of the butterfly valve, a protective tube assembly is sleeved on the outer side of the square upper transmission rod 25 and the lower transmission sleeve 24 of the switch assembly 2, an upper valve box 42 of the valve box assembly 4 is floatingly installed on the lower valve box 41, an anti-theft card 47 is provided in the valve box assembly 4, and the left and right ends of the butterfly plate 52 of the main valve body 5 are hinged to the valve body 51.

[0020] The working principle and beneficial effects of the above technical solution are as follows: the butterfly valve box assembly 4 protects the switch assembly 2, and the valve box assembly has an anti-theft function. The upper valve box 42 is a floating structure relative to the lower valve box 41, and is adaptive to the settlement and height change of the road hardening layer. The switch assembly 2 is used to transmit torque to open and close the underground main valve body 5, and adopts a protective pipe assembly design, which is adaptive to the buried depth while preventing soil corrosion. At the same time, the switch assembly 2 displays the opening of the butterfly valve, and the main valve body 5 realizes the on-off requirements of the pipeline; The present invention utilizes a floating valve box assembly 4, a telescopic switch assembly 2 and a main valve body to achieve the transmission of valve torque. The design of the anti-theft card 47 ensures that non-professionals cannot operate the valve, thereby preventing the manhole cover from being stolen. The floating design of the upper valve box 42 ensures that the valve box can adapt to the settlement and height changes of the road hardening layer to avoid damage in an open-air environment. The protective tube assembly of the switch assembly 2 ensures that the transmission mechanism cannot be corroded by the soil. The design of the valve position opening wheel 36 can intuitively understand the valve opening and effectively adjust the valve. The hinge-integrated design of the butterfly plate 52 improves the valve body's ability to resist elliptical deformation and ensures the stability of the valve structure, so that when it bears the weight of the soil and pedestrians and vehicles on the road, it will not affect the sealing performance of the butterfly valve sealing surface and the portability of the valve opening and closing. At the same time, the three cooperate with each other, so that the valve switch can be set on the surface, and personnel can directly operate the underground valve to avoid the need to repeatedly dig up the surrounding roads.

[0021] Example 2 On the basis of Example 1, the protective tube assembly of the switch assembly 2 includes a lower protective tube 21 and an upper protective tube 23, one end of the lower protective tube 21 is connected to the limit sleeve 22 by bolts, the limit sleeve 22 is fixed on the turbine reducer 1, the other end of the lower protective tube 21 is slidably connected to the upper protective tube 23, the top of the upper protective tube 23 is bolted with a valve position opening mechanism 3, a lower transmission sleeve 24 is provided in the lower protective tube 21, the lower transmission sleeve 24 is nested and connected to the worm of the turbine reducer 1 through a cotter pin, the top of the lower transmission sleeve 24 is slidably connected to a square upper transmission rod 25 with a cotter pin, and the top of the square upper transmission rod 25 is connected to the valve position opening mechanism 3.

[0022] The working principle and beneficial effects of the above technical solution are as follows: the valve position opening mechanism 3 is opened and closed manually, the square upper transmission rod 25 is connected to the valve position opening mechanism 3 for torque transmission, the square upper transmission rod 25 is square steel, the lower transmission sleeve 24 is a steel pipe with a square hole, the square upper transmission rod 25 is inserted into the square hole of the lower transmission sleeve 24 to form a telescopic effect, and at the same time, the square shaft cooperates with the square hole to transmit the torque of opening and closing the valve, the square upper transmission rod 25 is limited by a cotter pin, and when working, the valve position opening mechanism 3 drives the square upper transmission rod 25 to rotate, the square upper transmission rod 25 drives the lower transmission sleeve 24 to rotate, and the lower part of the lower transmission sleeve 24 drives the worm to rotate, driving the turbine reduction box 1 to realize the opening and closing of the valve, and the lower protective tube 21 is limited by bolts to prevent separation, and the upper protective tube 23 and the lower protective tube 21 slide against each other to realize the telescopic structure; The present invention utilizes a protective tube divided into two sections, an upper section and a lower section, with a small inner section and a large outer section, which are superimposed in a sleeve-like manner to form a telescopic effect. When buried deep, the inner transmission rod is protected to prevent soil from entering its inner cavity and affecting the rotation of the inner transmission rod. At the same time, the transmission rod is also divided into two sections, an upper section and an lower section, and the square-hole steel tube and the square steel are nested with each other. While cooperating with the telescopic effect of the protective tube, the rectangular matching limiting property is used to ensure the stability and efficiency of the transmission torque.

[0023] Example 3 On the basis of Example 2, the valve position opening mechanism 3 includes a valve switch shaft 31, which is nested and connected to the square upper transmission rod 25 through a cotter pin, and a turntable 32 is keyed on the valve switch shaft 31, and a planetary gear 33 is rotatably connected to the turntable 32. The turntable 32 penetrates and is rotatably connected to a transmission gear cap 34, and the transmission gear cap 34 is fixed to the top of the upper protective tube 23 by bolts. A cap 35 is bolted to the top of the transmission gear cap 34, and a valve position opening wheel 36 is penetrated and rotatably connected to the center of the cap 35. The valve position opening wheel 36 is slidably connected to the transmission gear cap 34, and the planetary gear 33 is meshed with the valve position opening wheel 36. The valve position opening mechanism 3 is provided with a valve box assembly 4 outside.

[0024] The working principle and beneficial effects of the above technical solution are as follows: the valve switch shaft 31 is rotated by manual rotation, and the valve switch shaft 31 transmits torque to the lower square upper transmission rod 25 to open and close the valve. At the same time, the rotation of the valve switch shaft 31 drives the turntable 32 to rotate, and the rotation of the turntable 32 drives the planetary gear 33 to move in a circular motion. The movement of the planetary gear 33 drives the valve position opening wheel 36 to rotate. The rotation angle of the valve switch shaft 31 is consistent with the turntable 32 and the valve position opening wheel 36. The valve opening is observed according to the rotation angle of the valve position opening wheel 36. The present invention utilizes the structural principle of the planetary differential gear train to keep the rotation angle of the valve position opening wheel 36 and the valve switch shaft 31 consistent, thereby intuitively and synchronously displaying the opening and closing status of the valve, making it easy for operators to judge the on-off status of the valve and the pipeline and perform the next operation.

[0025] Example 4 On the basis of Example 1, the valve box assembly 4 includes a lower valve box 41, an upper valve box 42 is slidably connected inside the lower valve box 41, a valve box cover 43 is nested and connected to the top of the upper valve box 42, a limit screw 44 is fixed to one side of the valve box cover 43, the limit screw 44 passes through and is slidably connected to the seat of the upper valve box 42, an anti-theft bolt 45 is threadedly connected to the other side of the valve box cover 43, a nut 46 is threadedly connected to the bottom of the anti-theft bolt 45, an anti-theft card 47 is sleeved on the anti-theft bolt 45 and clamped between the nuts 46, and the anti-theft card 47 and the seat of the valve box cover 43 cooperate with each other.

[0026] The working principle and beneficial effects of the above technical solution are as follows: the upper valve box 42 is sleeved in the lower valve box 41, so that the upper valve box 42 can float up and down in the lower valve box 41, and a valve box cover 43 is nested on the top of the upper valve box 42. The limit screw 44 enables the valve box cover 43 to move up and down on the top of the upper valve box 42 while being unable to separate from the upper valve box 42, and the anti-theft bolt 45, nut 46 and anti-theft card 47 on the valve box cover 43 cooperate with the upper valve box 42 through the anti-theft card 47 to ensure that the valve box cover 43 cannot be opened. When it is necessary to punch the valve box cover 43, the anti-theft bolt 45 is rotated 90° with an inner hexagonal wrench, and the anti-theft card 47 is separated from the cooperation of the upper valve box 42, so that the valve box cover 43 can be opened. When it is necessary to close the valve box cover 43, the reverse operation can be performed; The present invention utilizes the design of the upper valve box 42 as a floating structure relative to the lower valve box 41, which is adaptive to the settlement and height change of the road hardening layer. The upper valve box 42 does not protrude or recessed from the road surface, ensuring that the road surface is flat, and people and vehicles can pass smoothly and noiselessly, safely, beautifully and flatly. The limiting screw 44 connects the valve box cover 43 and the upper valve box 42 as a whole and does not separate, preventing the valve box cover 43 from being lost when the valve box cover 43 is opened to switch the valve. The design of the anti-theft bolt 45, nut 46 and anti-theft card 47 ensures that the valve box cover 43 can only be opened by a dedicated person using a dedicated tool, and will not be lost or damaged, thereby avoiding causing travel safety for people and vehicles.

[0027] Example 5 On the basis of Example 1, the main valve body 5 includes a valve body 51, a butterfly plate 52 is arranged in the valve body 51, an upper end cover 53 and a lower end cover 54 are bolted to the left and right sides of the valve body 51 respectively, an upper valve shaft 55 passes through and is rotatably connected to the upper end cover 53 and the left side of the valve body 51, a lower valve shaft 56 passes through the right side of the valve body 51 and is rotatably connected to the lower end cover 54, a split clamping ring 57 is arranged between the upper valve shaft 55 and the lower valve shaft 56 and the valve body 51, the split clamping ring 57 is sleeved on the upper valve shaft 55 and the lower valve shaft 56, the centripetal ends of the upper valve shaft 55 and the lower valve shaft 56 are nested and fixed to the left and right sides of the butterfly plate 52 by a pin shaft 58, and a sealing pair 6 is arranged on the water inlet of the valve body 51.

[0028] The working principle and beneficial effects of the above technical solution are as follows: the output shaft of the turbine reduction box 1 drives the upper valve shaft 55 to rotate, and the upper valve shaft 55 drives the butterfly plate 52 to rotate around the lower valve shaft 56 and the upper valve shaft 55 through the pin shaft 58. The butterfly plate 52 rotates to control the opening and closing of the valve, and the split clamp ring 57 seals the upper valve shaft 55 and the lower valve shaft 56. The upper end cover 53 and the lower end cover 54 limit and fix the valve shaft and the split clamp ring 57. The sealing pair 6 ensures the sealing inside the valve when the butterfly plate 52 closes the valve. The present invention adopts an integral hinged design of the valve body 51, the upper valve shaft 55, the lower valve shaft 56 and the butterfly plate 52, and utilizes the tensile strength of the high-strength butterfly plate 52 to improve the anti-bending and elliptical resistance of the valve body 51, so that the deformation caused by the weight of soil and pedestrians and vehicles on the road will not affect the sealing performance of the butterfly valve sealing surface and the ease of opening and closing of the valve. At the same time, the lateral design of the upper valve shaft 55, the lower valve shaft 56 and the butterfly plate 52 can effectively ensure the stability of the valve drive structure and prevent the valve from being unable to close due to deformation due to pressure.

[0029] Example 6 On the basis of Example 5, the sealing pair 6 includes an elastic stainless steel sealing ring 61, which is sleeved in the water inlet of the valve body 51, a rubber ring 62 is provided between the valve body 51 and the elastic stainless steel sealing ring 61, a fixing sleeve 63 and the elastic stainless steel sealing ring 61 are nested with each other, the fixing sleeve 63 is fixed in the water inlet of the valve body 51 by bolts, and the butterfly plate 52 and the elastic stainless steel sealing ring 61 cooperate with each other.

[0030] The working principle and beneficial effects of the above technical solution are as follows: when the butterfly plate 52 rotates from the open state to the closed state, the butterfly plate 52 squeezes the elastic stainless steel sealing ring 61 to expand outward, and the elastic stainless steel sealing ring 61 squeezes the rubber ring 62, and the three cooperate with each other to seal the water inlet of the valve, and when the butterfly plate 52 rotates from the closed state to the open state, the elastic stainless steel sealing ring 61 and the rubber ring 62 are reset; The present invention utilizes an elastic stainless steel sealing ring 61 and a rubber ring 62 as a sealing pair 6. This structure is an elastic self-compensating stainless steel metal hard sealing structure. The sealing is safe and reliable. The stainless steel has a long service life and is resistant to erosion, aging, and abrasion. At the same time, the design of the elastic stainless steel sealing ring 61 can utilize water pressure to achieve self-locking and maintain the effectiveness of the seal during sealing.

When the butterfly valve needs to be rotated, the rotating structure 8 rotates the butterfly valve around the X-axis axis. When the butterfly valve needs to move forward and backward, the electric lead screw 76 drives the pressure rod 77 to move forward and backward on the slide rail 75, thereby realizing the forward and backward movement of the butterfly valve. When the butterfly valve rotates in the Z-axis direction, the driving wheel 73 drives the central rotating wheel 72 to rotate, so that the upper part of the placement plate 71 rotates as a whole, realizing the rotation of the butterfly valve in the Z-axis direction; The present invention utilizes the design of the cutting chip recovery device 9 to effectively recover the cutting oil, avoid environmental pollution, and press the cutting chips into cakes for easy collection and unified treatment; The electric lead screw 76, gear set, hydraulic telescopic rod 79 and rotating structure 8 realize the three-dimensional angle movement and rotation of the butterfly valve, which is convenient for drilling and boring operations during the butterfly valve processing, improves the convenience of manual operation, and reduces the difficulty of butterfly valve processing.

[0034] The working principle and beneficial effects of the above technical solution are as follows: the driving member 87 drives the driving shaft 86 to rotate, the driving shaft 86 drives the gear 85 to rotate, the gear 85 and the driven wheel 83 mesh with each other and rotate, so that the boss 84 rotates, the boss 84 rotates and drives the top fixing rod 710 to rotate, when the driven wheel 83 rotates, the angle pointer 88 on the driven wheel 83 is driven to slide along the angle slot 89, and the driven rotation angle is displayed in real time; The present invention utilizes a gear set for transmission to realize the rotation of the top fixing rod 710. This design enables the top fixing rod 710 to have higher transmission efficiency, higher load-bearing capacity and more stable rotation speed when rotating. Moreover, when the top fixing rod 710 is stationary, due to the characteristics of the gear set, within the allowable load-bearing range, no sliding will occur to cause deviation in processing accuracy. At the same time, the design of the angle pointer 88 can more intuitively observe the rotation angle of the valve component and fine-tune the valve component according to the rotation angle.

[0035] Example 9 On the basis of Example 1, the cutting chip recovery device 9 includes a recovery bucket 91, which is fixed on a recovery box 93. An electric symmetrical rotating shaft 92 is provided below the recovery bucket 91, and the electric symmetrical rotating shaft 92 is rotatably connected to the recovery box 93. A plurality of corresponding shear blades 94 are fixed on the electric symmetrical rotating shaft 92. An electric rotating shaft 95 is provided below the electric symmetrical rotating shaft 92, and the electric rotating shaft 95 is rotatably connected to the recovery box 93. A spiral centrifugal cylinder 96 is fixed on the electric rotating shaft 95, and a spiral oil seepage seam 97 is provided on the side of the spiral centrifugal cylinder 96. A separation component 10 is provided below the spiral centrifugal cylinder 96.

[0036] The working principle and beneficial effects of the above technical solution are as follows: After the chips fall into the recovery bucket 91, they fall between the shear blades 94 along the recovery bucket 91. The shear blades 94 shear the chips with a longer length under the drive of the electric symmetrical shaft 92, so that the chips are within a certain length range. After being sheared, the chips fall into the spiral centrifugal cylinder 96 for deoiling. The spiral centrifugal cylinder 96 rotates under the drive of the electric shaft 95. Under the action of centrifugal force, the chips dry the cutting oil attached to the chips and are thrown out of the spiral centrifugal cylinder 96 from the spiral oil seepage gap 97. At the same time, the chips fall along the spiral centrifugal cylinder 96 and enter the separation component 10. The present invention utilizes the shearing blade 94 and the electric symmetrical rotating shaft 92 to control the length of the chips, ensuring that the length of the chips can enter the spiral centrifugal barrel 96 for deoiling, avoiding the entanglement of longer chips during the deoiling process, resulting in chip blockage. At the same time, the design of the spiral centrifugal barrel 96 can utilize the centrifugal force to throw the cutting oil attached to the chips out from the spiral oil seepage gap 97 while ensuring that the chips fall along the spiral centrifugal barrel 96 for separation.

[0037] Example 10 On the basis of Example 9, the separation component 10 includes an oil receiving pan 101, which is arranged on the outside of the spiral centrifugal cylinder 96, and the oil receiving pan 101 is fixed on the recovery box 93. The oil receiving pan 101 is connected to the oil pipeline 102. An inclined slide 103 is provided below the spiral centrifugal cylinder 96, and the inclined slide 103 is fixed at the center of the oil receiving pan 101. The electric shaft 95 passes through the inclined slide 103, and a pressure groove 104 is provided below the discharge port of the inclined slide 103. A telescopic pressure plate 105 is slidably connected in the pressure groove 104, and an electric flap 106 is rotatably connected below the pressure groove 104. A pressure sensor 107 is provided in the pressure groove 104, and the pressure sensor 107 is electrically connected to the electric flap 106.

[0038] The working principle and beneficial effects of the above technical solution are as follows: after the cutting oil is thrown out of the spiral centrifugal cylinder 96, it collides with the oil receiving pan 101 under the action of gravity and centrifugal force and falls along the oil receiving pan 101 into the oil pipeline 102, and the de-oiled cutting chips are separated from the spiral centrifugal cylinder 96 and fall into the inclined slide 103 below. The cutting chips enter the pressing groove 104 along the inclined slide 103 and accumulate in the pressing groove 104. After a certain period of time, the telescopic pressing plate 105 pushes the cutting chips forward in the pressing groove 104 and squeezes them at the end of the pressing groove 104 to press the cutting chips into a pancake shape. At the same time, after the pressure sensor 107 senses the pressure, the electric flap 106 is opened. When the telescopic pressing plate 105 retreats, the pancake-shaped cutting chips fall, and then the electric flap 106 is reset. The present invention utilizes the parabola principle to collect all the cutting oil in the oil receiving pan 101, thereby avoiding the pollution of the equipment and the environment by the splash of the cutting oil. The cutting oil can be recycled after filtering, thereby improving the economic benefits. At the same time, the telescopic pressing plate 105 is used to squeeze the cutting chips into a cake shape, which is beneficial to the collection and centralized treatment of the cutting chips and reduces the impact of waste materials on the environment.
