Description

Technical Field

[0001] The invention relates to the technical field of valve installation devices, in particular to a valve installation device used for gas filling. Background Art

[0002] Valves are pipe accessories used to open and close pipes, control flow direction, and adjust and control the parameters of the conveyed medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid conveying systems, with functions such as shut-off, regulation, flow diversion, prevention of backflow, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems come in a wide variety of varieties and specifications, from the simplest shut-off valves to various valves used in extremely complex automatic control systems.

[0003] A Chinese patent with publication number CN105382511A discloses a one-time valve installation device, including a workbench, an upper clamping cylinder, a lower lifting cylinder, a valve plate fixing disk, a valve seat fixing disk and a valve body fixing disk, wherein the upper clamping cylinder is fixed to the workbench through an upper cylinder bracket, and a clamping disk is fixed on the piston rod of the upper clamping cylinder; the valve body fixing disk is fixed to the workbench, and a valve stem cylinder is provided on one side of the workbench, and a valve stem fixing sleeve is provided on the piston rod of the valve stem cylinder, and an opening is provided on one side of the valve stem fixing sleeve, and the valve stem fixing sleeve is directly opposite to the valve body fixing disk, thereby adding a function of installing a valve stem. After the valve body, valve plate and valve seat are installed, one end of the valve stem is placed on the valve stem fixing sleeve, and the valve stem cylinder is started, and the valve stem cylinder automatically presses the valve stem into the valve body without the need for secondary processing, thereby greatly improving assembly efficiency.

[0004] In the precise installation of the valve, it is first necessary to apply adhesive on the pressing surface of the valve, and then press it onto the inner tank and cure it. This step often requires manual on-site mixing of glue, and then applying adhesive to the pressing surface of the valve, and finally continuing the press-fitting and curing of the valve and the inner tank. In this process, the mixed glue will have the risk of precipitation and agglomeration during the static process. Secondly, the manual application of adhesive can easily cause the adhesive to stick to itself or the desktop, which in turn causes other parts of the valve seat placed on the desktop to stick to the adhesive. Finally, the adhesive applied to the valve is easily cured due to the influence of temperature, making it difficult to install on the end of the inner tank.

[0005] To this end, the present invention proposes a valve installation device for gas filling to solve the above-mentioned problem. Summary of the invention

DETAILED DESCRIPTION

[0044] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0045] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0046] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0047] Example 1

[0048] Reference Figure 1 to Figure 14 As shown, it is the first embodiment of the present invention, which provides a valve installation device for gas filling, including an inner tank structure and a machine tool:

[0049] The inner liner structure includes an inner liner 200 and a metal valve seat 210. The inner liner 200 is hollow and has openings at both ends, and the openings are adapted to the metal valve seat 210.

[0050] The machine tool includes a protective cover 100, a track structure 300 and a valve seat mounting structure 400 fixed on the track structure 300. The protective cover 100 is arranged on the outside of the track structure 300. The valve seat mounting structure 400 includes a clamping seat 410, a hollow rotating structure 420 and a glue coating structure 430. The hollow rotating structure 420 clamps the metal valve seat 210 and drives the metal valve seat 210 to rotate. The clamping seat 410 clamps the inner liner 200. The clamping seat 410 is transported to the hollow rotating structure 420 by the track structure 300, and drives the inner liner 200 to be press-fitted and installed in the metal valve seat 210.

[0051] Reference Figure 1 , Figure 2 as well as Figure 3 As shown, the clamping seat 410 is engaged with the track structure 300 and is transported by the track structure 300; the hollow rotating structure 420 and the glue coating structure 430 are fixed on the track structure 300, the hollow rotating structure 420 is located between the clamping seat 410 and the glue coating structure 430, and the hollow rotating structure 420 is located on the same straight line as the clamping seat 410 and the glue coating structure 430.

[0052] The hollow rotating structure 420 is configured to be in a first motion state of rotating along the center of the metal valve seat 210 and a second motion state of rotating along the vertical center line of the hollow rotating structure 420 itself; the hollow rotating structure 420 is transformed from the first motion state to the second motion state, which is driven by the rotating motor 450.

[0053] When the hollow rotating structure 420 is in a first motion state, the metal valve seat 210 rotates along with the hollow rotating structure 420 so that the pressing surface of the metal valve seat 210 is coated with glue by the glue coating structure 430 during the rotation; when the hollow rotating structure 420 is in a second motion state, the metal valve seat 210 rotates along with the hollow rotating structure 420 so that the pressing surface of the metal valve seat 210 changes from facing the glue coating structure 430 to facing the clamping seat 410.

[0054] Specifically, when the glue coating process is started, the metal valve seat 210 rotates along with the hollow rotating structure 420 so that the metal valve seat 210 rotates along its own center line, so that the contact surface between the metal valve seat 210 and the inner liner 200 is coated with glue by the glue coating structure 430;

[0055] When entering the installation process, the metal valve seat 210 rotates with the hollow rotating structure 420, so that the metal valve seat 210 changes from facing the glue coating structure 430 to the clamping seat 410. After the position of the metal valve seat 210 is changed, the track structure 300 transports the clamping seat 410 to the hollow rotating structure 420, drives the inner liner 200 to be press-fitted and installed in the metal valve seat 210, and stands for a period of time. After the glue between the inner liner 200 and the metal valve seat 210 is solidified, the metal valve seat 210 is fixed to the end of the inner liner 200.

[0056] The solidified metal valve seat 210 and the inner liner 200 are removed, the hollow rotating structure 420 is reset, and the clamping surface of the hollow rotating structure 420 is changed from facing the clamping seat 410 to facing the glue coating structure 430 .

[0057] Also includes:

[0058] A track structure 300, which includes a mounting frame, a driving structure, and an extrusion structure;

[0059] The mounting frame includes a supporting frame 432 and a rotating frame 433. The bottom end of the supporting frame 432 is connected to a base 431 by bolts, and the base 431 is connected to the track structure 300 by bolts;

[0060] The extrusion structure includes a glue storage tank 434 and a connecting pipe 438 which are inserted into each other. The glue storage tank 434 is used to store two glues for synthesizing adhesive. The glue storage tank 434 includes a liquid storage round tank 4341 and a piston 4344. The piston 4344 pushes the glue in the liquid storage round tank 4341 and is received by the connecting pipe 438. A plurality of blades 4386 are fixed to the wall of the connecting pipe 438. The rotating rotating frame 433 drives the glue storage tank 434 and the connecting pipe 438 to rotate, so as to drive the glue to impact the blades 4386 to synthesize adhesive.

[0061] The driving structure includes a power transmission structure 437, a transmission gear set 436 and a planetary gear set 435. The power transmission structure 437 drives the rotating frame 433 to rotate. The rotating rotating frame 433 drives the planetary gear set 435 to rotate with the center line of the transmission gear set 436 as the center of the circle. The planetary gear set 435 and the transmission gear set 436 are meshed and driven to rotate. The self-rotating planetary gear set 435 drives the piston 4344 to move to squeeze out the glue in the liquid storage tank 4341.

[0062] The coating structure 440 is used to receive the stirred glue and coat it on the metal valve seat 210 .

[0063] Among them, refer to Figure 5 and Figure 6As shown, the power transmission structure 437 and the transmission gear set 436 are positioned on the support frame 432, and the transmission gear set 436 is configured as a fixed gear 4361, a limiting column 4362 extends from its surface, and the fixed gear 4361 is fixed to the surface of the support frame 432 by the limiting column 4362, so that the fixed gear 4361 is positioned on the surface of the support frame 432 and cannot rotate.

[0064] A rotating rod passes through the top of the support frame 432, and the two ends of the rotating rod are respectively fixed with the power transmission structure 437 and the rotating frame 433. The power transmission structure 437 drives the rotating frame 433 to rotate through the rotating rod. The power transmission structure 437 and the rotating frame 433 are supported and positioned by the support frame 432 through the rotating rod.

[0065] Specifically, the power transmission structure 437 includes a motor 4371 installed on the inner end surface of the support frame 432, a driving main gear 4372 and a driving sub-gear 4373 installed on the outer end surface of the support frame 432. The driving main gear 4372 is fixed to the output end of the motor 4371 to operate synchronously with the output end of the motor 4371, and at the same time engages with the driving sub-gear 4373 to drive the driving sub-gear 4373 to rotate. The rotating driving sub-gear 4373 drives the rotating frame 433 to rotate.

[0066] Reference Figure 7-Figure 11 As shown, the rotating frame 433 includes a hexagonal frame 4331, an extension frame 4332 and a transverse cylinder 4333. The extension frames 4332 are in two groups. Both groups of extension frames 4332 are fixed to one side of the hexagonal frame 4331 close to the fixed gear 4361. The transverse cylinder 4333 is fixed to one end of the extension frame 4332 away from the hexagonal frame 4331. The two groups of extension frames 4332 are symmetrical with respect to the hexagonal frame 4331.

[0067] There are two planetary gear sets 435, and the two planetary gear sets 435 are symmetrical about the center line of the fixed gear 4361. The planetary gear set 435 includes a linkage main gear 4351, a linkage sub-gear 4352 and a turbine 4353. A sleeve shaft penetrating the rotating frame 433 is provided between the linkage main gear 4351 and the linkage sub-gear 4352. The linkage main gear 4351 and the linkage sub-gear 4352 are fixedly connected through the sleeve shaft. The turbine 4353 is provided at both ends of the liquid storage tank 4341 and meshes with the linkage sub-gear 4352.

[0068] A partition plate 4342 is provided in the liquid storage tank 4341 for dividing the inner cavity of the liquid storage tank 4341. The piston 4344 includes a piston rod and a piston plate connected as one body. The inner thread of the piston rod is connected with a threaded rod 4345. The turbine 4353 is fixed to the end of the threaded rod 4345. The linkage pinion 4352 drives the turbine 4353 to rotate so that the threaded rod 4345 rotates in the piston rod, and the piston rod is driven to move in the liquid storage tank 4341.

[0069] A limiting plate 4346 is welded inside the liquid storage round tank 4341 , and the limiting plate 4346 penetrates the piston plate and the partition plate 4342 . The moving liquid storage round tank 4341 is guided by the limiting plate 4346 , and then linearly displaces inside the liquid storage round tank 4341 .

[0070] Principle: A support frame 432 and a rotating frame 433 are fixed on the support frame 432 , wherein the bottom of the support frame 432 is connected to the base 431 by bolts, and the base 431 is fixed on the track structure 300 .

[0071] The driving structure is responsible for providing power to ensure that the above process proceeds smoothly. The structure is mainly composed of a power transmission structure 437, a transmission gear set 436 and a planetary gear set 435. The power transmission structure 437 acts as a power source and directly drives the rotating frame 433 to rotate through a rotating rod. The rotation of the rotating frame 433 not only drives the rotation of the glue storage tank 434 and the connecting pipe 438, but also indirectly drives the self-rotation of the planetary gear set 435. Specifically, while the rotating frame 433 drives the planetary gear set 435 to rotate around the center line of the transmission gear set 436, due to the meshing action between the planetary gear set 435 and the transmission gear set 436, the planetary gear set 435 will also spin.

[0072] Specifically, the rotation of the rotating frame 433 drives the two planetary gear sets 435 fixed thereon to perform orbital motion around the center line of the transmission gear set 436. While they are orbiting around the transmission gear set 436, they are forced to spin along their own axis due to the meshing of the linkage main gear 4351 with the gears of the transmission gear set 436. The spin motion of the linkage main gear 4351 is transmitted to the turbine 4353 through the linkage sub-gear 4352. The turbine 4353 forces the threaded rod 4345 to rotate inside the piston rod, further pushing the piston 4344 to move in a straight line direction inside the liquid storage tank 4341, thereby squeezing the glue in the liquid storage tank 4341, so that it is discharged through the connecting pipe 438 and finally received by the coating structure 440, and evenly coated on the surface of the metal valve seat 210.

[0073] Among them, the two sets of planetary gear sets 435 move synchronously, driving the two sets of pistons 4344 to move in a straight line direction in the liquid storage tank 4341. The movement of the two sets of pistons 4344 squeezes the glue in the corresponding liquid storage tank 4341 respectively, so that the two glues are squeezed into the connecting pipe 438 synchronously.

[0074] The extrusion structure is the core part of the device, which includes two components, a glue storage tank 434 and a connecting pipe 438, which are inserted into each other. The glue storage tank 434 serves as a storage unit, and contains two different types of glue inside, which will be mixed into the final required synthetic adhesive. A piston 4344 is designed inside the glue storage tank 434. When the piston 4344 moves, the glue can be pushed from the glue storage tank 434 to the connecting pipe 438. A plurality of blades 4386 are fixed on the wall of the connecting pipe 438. When the glue storage tank 434 and the connecting pipe 438 rotate with the rotation of the rotating frame 433, the blades 4386 continuously stir the glue to fully mix it and form a uniform synthetic adhesive.

[0075] By synchronously moving the two sets of pistons 4344, it can be ensured that the two glue liquids are always extruded at the same rate and the same ratio, which is used to accurately control the synthetic ratio of the adhesive and ensure the synthetic accuracy of the adhesive; secondly, the two glue liquids are synchronously extruded and enter the connecting tube 438, and are instantly mixed by multiple sets of blades 4386 on the wall of the connecting tube 438. The instant mixing method can avoid the solidification or deterioration of the pre-mixed glue liquid due to long-term storage, and at the same time ensure that the two glue liquids are uniform in composition when entering the subsequent coating step, thereby ensuring the efficiency of the adhesive and maximizing the utilization efficiency of the materials.

[0078] The connecting pipe 438 includes a three-way pipe 4381 and an intermediate pipe 4383 which are connected as one body. The three-way pipe 4381 is inserted into the two sets of liquid outlet pipes 4343 and guides the glue into the intermediate pipe 4383. A set of bearings 4382 are sleeved on the outer surface of the intermediate pipe 4383. The bearings 4382 are engaged with the inside of the rotating frame 433. The bearings 4382 are used to increase the outer diameter of the intermediate pipe 4383 so as to fit tightly with the rotating frame 433.

The blades 4386 act on the glue liquid to mix the two glue liquids to synthesize the adhesive;

[0081] A set of protective cover parts 439 is fixed to the top of the support frame 432. The protective cover part 439 includes a protective tank 4391 and a drainage component 4392. The protective tank 4391 is covered on the outside of the extrusion tube 4384 and supports the middle pipe 4383. The drainage component 4392 blocks the mouth of the extrusion nozzle 4385 and moves in the extrusion nozzle 4385. The drainage component 4392 is used to receive the mixed glue in the extrusion tube 4384.

[0082] The drainage assembly 4392 includes a conical nozzle and a liquid guide tube connected to the conical nozzle. The liquid guide tube passes through the protective tank 4391 and extends back to the blade 4386.

[0083] like Fig.11 As shown, the smear structure 440 includes an installation box 4401 fixed to the surface of the supporting frame 432, an upper inclined groove 4402 is opened at the top of the installation box 4401, and a lower inclined groove 4403 is opened on the inclined side of the installation box 4401, the upper inclined groove 4402 and the lower inclined groove 4403 are connected, and the liquid outlet of the liquid guide tube is located directly above the installation box 4401.

[0084] The cross-section of the upper chute 4402 is triangular, and is used to allow the received glue to flow to the surface of the installation box 4401 under the action of gravity. A group of coating rollers are provided inside the lower chute 4403. The coating rollers are parallel to the inclined surfaces of the metal valve seat 210. The rotating metal valve seat 210 drives the coating rollers to rotate through friction, so that the adhesive on the surface of the coating rollers adheres to the surface of the metal valve seat 210.

[0085] The coating roller includes an integrally connected rotating roller 4405 and a rubber layer 4404. The rubber layer 4404 rotates inside the installation box 4401, and a group of installation tubes 4406 for inserting the rotating roller 4405 are fixed at the bottom of the installation box 4401. A film is attached to the outer layer of the rubber layer 4404. The rubber layer 4404 is made of thickened rubber so that the surface of the coating roller extends out of the lower inclined groove 4403 and contacts the surface of the metal valve seat 210. At the same time, the characteristics of the rubber layer 4404 and the characteristic of deformation under pressure make the coating roller completely close to the surface of the metal valve seat 210.

[0086] Secondly, the film can adhere to the outer surface of the rubber layer 4404 as the rubber layer 4404 deforms, and does not absorb the glue, so as to ensure that the glue adhering to the surface of the film can be completely attached to the surface of the metal valve seat 210.

[0087] Specifically, the two groups of liquid outlet pipes 4343 are respectively connected to the two independent chambers of the liquid storage tank 4341, and the two glue liquids are respectively discharged into the interior of the connecting pipe 438. The end of the intermediate pipe 4383 away from the three-way pipe 4381 is connected to the extrusion pipe 4384. The blades 4386 are laid on the entire inner surface of the intermediate pipe 4383 and the extrusion pipe 4384, acting on the glue liquid so that the two glue liquids are mixed to synthesize the adhesive. The surface of the extrusion pipe 4384 is provided with a conical cylindrical extrusion nozzle 4385, which is used to discharge the glue liquid and ensure that the glue liquid does not seep out from the connection between the extrusion pipe 4384 and the extrusion nozzle 4385.

[0088] The coating structure 440 includes an installation box 4401 fixed to the surface of the support frame 432. An upper chute 4402 is provided at the top of the installation box 4401, and a lower chute 4403 is provided at the oblique side. The upper chute 4402 and the lower chute 4403 are connected, and the liquid outlet of the liquid guide tube is located directly above the installation box 4401. The cross section of the upper chute 4402 is triangular, and is used to flow the received glue to the surface of the installation box 4401 under the action of gravity. A group of coating rollers are provided inside the lower chute 4403. The coating rollers are parallel to the inclined surface of the metal valve seat 210. The rotating metal valve seat 210 drives the coating rollers to rotate through friction, so that the adhesive on the surface of the coating rollers adheres to the surface of the metal valve seat 210. The rotating coating rollers contact the inclined surface of the installation box 4401 during the rotation process to dip the adhesive. The coating roller includes an integrally connected rotating roller 4405 and a rubber layer 4404. A film is attached to the outer layer of the rubber layer 4404. The film can adhere to the outer surface of the rubber layer 4404 as the rubber layer 4404 deforms, does not absorb glue, and has little friction with the installation box 4401.

[0089] The triangular cross-section design of the installation box 4401 allows the glue to flow evenly to the surface of the installation box 4401 under the action of gravity. The coating roller is designed to be parallel to the inclined surface of the metal valve seat 210. The coating roller is driven by rotating friction to dip into the glue and is evenly coated on the surface of the metal valve seat 210 through the coating roller.

[0090] The film on the outer layer of the coating roller does not absorb the glue, and at the same time, the glue adheres to the surface of the film by virtue of its adhesion, thus avoiding the waste of glue and the problem of uneven coating. The thickened rubber and film design of the rubber layer 4404 enables the coating roller to adapt to different surface shapes and roughness, and it can be deformed by pressing to fit tightly against the surface of the metal valve seat 210, thereby improving the coating quality and scope of application.

[0091] The glue liquid squeezed out of the liquid storage round tank 4341 in this device each time is the amount of adhesive to be applied to the surface of the metal valve seat 210 at a time. The extrusion tube 4384 and the middle pipe 4383 are also equipped with heaters for heating the glue liquid. First, the amount of glue liquid required to be heated by the heater is small, which saves energy, quickly increases the temperature of the glue liquid, and ensures that the adhesive reaches the ideal fluidity in a short time. This can avoid the problem of adhesive solidification or coagulation caused by too low temperature. At the same time, the external protective tank 4391 has a heat preservation effect on the three-way pipe 4381 to prevent heat from being lost too quickly. The design of the protective tank 4391 can not only protect the internal heater and mixing pipe, but also maintain a relatively stable temperature environment to ensure that the adhesive maintains a suitable temperature during the entire transmission process.

[0092] The rotating rotating frame 433 drives the glue storage tank 434 and the connecting pipe 438 to rotate, so that the glue in the extrusion tube 4384 rotates continuously under the action of centrifugal force. This rotational motion helps to evenly heat the glue and avoid local overheating or uneven cooling. At the same time, the rotation can also promote the full mixing of the two glues, ensuring that the mixed adhesive has uniform composition and performance.

[0093] The dual effects of heating and rotation can effectively prevent the adhesive from solidifying or clogging in the pipe. The heater ensures that the adhesive is always kept within the appropriate temperature range, while the rotational motion helps maintain the fluidity and uniformity of the adhesive, reducing the risk of precipitation and agglomeration.
