Description

Technical Field

[0001] The utility model belongs to the technical field of leakage detection devices, and in particular relates to a leakage detection device for a gas valve of a reciprocating compressor. Background Art

[0002] For example, the Chinese utility model patent with the publication number CN216247075U discloses a leak detection device for a reciprocating compressor air valve. The leak detection device with this structural design improves the detection accuracy of the air valve by setting a No. 1 pressure gauge and a No. 2 pressure gauge. The leaking part of the air valve can be specifically detected by setting a temperature detection device, thus avoiding the staff from checking one by one and improving the work efficiency. Therefore, it can be seen that the existing leak detection devices basically meet people's practical needs, but the following problems still exist.

[0003] When the operator needs to replace the gas valve body, the operator needs to open the door panel on the tank body first. When the door panel is opened, the operator puts his hand into the tank body through the door frame, and then the operator turns the bolts that connect the connecting plates to each other so that the bolts no longer fix the two sets of connecting plates. Then, the operator pulls the connecting plates, and the connecting plates are separated from the surface of the gas valve body, thereby disassembling the gas valve body. However, since the opening of the door frame of the tank body is small, and the bolts are installed around the connecting plates, and part of the threads are on the inside of the tank body, when the operator turns the bolts set on the inside of the tank body, due to the small space in the tank body, the operator may not be able to quickly find the bolts, and when turning the bolts, the operator may not be able to quickly turn the bolts, so that the threads no longer fix the connecting plates. For this reason, we propose a leak detection device for a reciprocating compressor gas valve. Utility Model Content

[0004] The utility model provides a leakage detection device for a reciprocating compressor air valve. An operator pushes a mounting ring, and the mounting ring drives a sliding block to slide in a sliding groove through a sleeve ring, so that the mounting ring drives a threaded rod to rotate around a connecting plate, and moves the threaded rod to a door frame opened on the surface of a tank body. Then the operator twists the threaded rod, thereby improving the convenience of the operator twisting the threaded rod.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a leak detection device for a reciprocating compressor air valve, comprising a tank body, a connecting plate, an air valve body and an air pipe, a connecting plate is arranged in the middle of the tank body, and the air valve body is installed between two groups of connecting plates, an air pipe that passes through the tank body is fixed to the end of the connecting plate, a plate eave is fixed to the surface of the connecting plate, and a ring is sleeved on the end of the plate eave, a slider is fixed on one side of the ring and the plate eave is fitted to each other, and a slide groove is sleeved on the surface of the slider, a mounting ring is fixed to the outer wall of the ring, and threaded rods are penetrated all around the mounting ring.

[0006] Furthermore, the surface of the mounting ring is fitted with a fixing block matching the number of the threaded rods, and a loading slot is inserted in the middle of the fixing block, a threaded rod is inserted in the middle of the loading slot, a baffle is slidably connected to the opening of the threaded rod, and a guide rod passing through the mounting ring is fixed on one side of the fixing block and the mounting ring that are fitted together.

[0007] Furthermore, the surface of the guide rod is symmetrically provided with second traction grooves, and the middle of the second traction grooves is inserted with a first traction block fixed on the mounting ring.

[0008] Furthermore, the ends of the baffles are penetrated by traction rods fixed on the fixed blocks, positioning grooves are opened around the baffles, and positioning blocks fixed on the fixed blocks are inserted in the middle of the positioning grooves.

[0009] Furthermore, both side ends of the disc eaves are provided with first traction grooves, and the first traction grooves are embedded with second traction blocks fixed on the sleeve rings.

[0010] Furthermore, the first traction grooves are all configured as arc-shaped grooves, and the second traction blocks are all configured as arc-shaped blocks.

[0011] The beneficial effects of the utility model are:

[0012] 1. The reciprocating compressor gas valve leak detection device is provided with a collar, a slider, a slide groove and a mounting ring. When the operator pushes the mounting ring, the mounting ring drives the collar to move on the surface of the plate eaves, and the collar drives the slider to slide in the slide groove, so that the mounting ring drives the threaded rod to move, and the threaded rod is moved to the opening of the tank door frame. When the operator tightens the bolt, it is convenient for the operator to quickly find the threaded rod, thereby improving the convenience of the operator tightening the threaded rod.

[0013] 2. The reciprocating compressor air valve leak detection device is provided with a guide rod, a fixed block and a loading groove.

[0024] In order to further understand the content, features and effects of the utility model, the following embodiments are listed and described in detail with reference to the accompanying drawings.

[0025] Example:

[0026] See also Figure 1 - Figure 8A reciprocating compressor air valve leak detection device, comprising a tank body 1, a connecting plate 2, an air valve body 3 and an air pipe 4, a connecting plate 2 is arranged in the middle of the tank body 1, and an air valve body 3 is installed between two sets of connecting plates 2, an air pipe 4 penetrating the tank body 1 is welded to the end of the connecting plate 2, a plate eave 17 is welded to the surface of the connecting plate 2, and a collar 16 is sleeved at the end of the plate eave 17, a slider 8 is welded to one side where the collar 16 and the plate eave 17 are mutually attached, and a slide groove 7 is sleeved on the surface of the slider 8, an installation ring 5 is welded to the outer wall of the collar 16, and the installation ring 5 is penetrated all around There is a threaded rod 11. When the operator needs to replace the gas valve body 3, the operator first opens the sealing door set on the surface of the tank body 1, and then the operator pushes the installation ring 5, the installation ring 5 drives the collar 16 to move, and the collar 16 drives the slider 8 to slide in the slide groove 7. The slider 8 slides in the slide groove 7, so that the slider 8 pulls the collar 16, which is convenient for the collar 16 to slide stably on the surface of the disc eaves 17 and prevents the collar 16 from falling off the surface of the disc eaves 17, so that the collar 16 drives the threaded rod 11 to move through the installation ring 5, so that the threaded rod 11 is on the surface of the connecting disc 2. The operator then rotates the threaded rod 11 to move it to the door frame of the tank body 1, and then the operator twists the threaded rod 11 and the nut to make the nut and the threaded rod 11 threadably matched to separate the threaded rod 11 and the nut. Then the operator pulls the threaded rod 11, and the threaded rod 11 moves out of the mounting ring 5, thereby separating the two sets of connecting plates 2. For this reason, when the operator twists the threaded rod 11 set in the tank body 1, the operator no longer needs to insert the body into the tank body 1 to twist the threaded rod 11, which improves the convenience of the operator twisting the threaded rod 11, and in this embodiment, the tank body 1. The connecting plate 2, the air valve body 3 and the air pipe 4 are all technical parts of a leak detection device for a reciprocating compressor air valve authorized by a Chinese utility model patent with announcement number CN216247075U. Therefore, the structure, connection method and working principle of the tank body 1, the connecting plate 2, the air valve body 3 and the air pipe 4 will not be described in detail. The tank body 1, the connecting plate 2, the air valve body 3 and the air pipe 4 are prior arts, and the technical solution of this application has not improved them. Therefore, there is no need to disclose the specific model, circuit structure, etc. of the external controller, which does not affect the integrity of the technical solution of this application.

[0027] In other embodiments, the surface of the mounting ring 5 is fitted with fixing blocks 15 whose number matches that of the threaded rods 11, and the middle of the fixing blocks 15 is inserted with a loading groove 13, and the middle of the loading groove 13 is inserted with a threaded rod 11, and a guide rod 10 penetrating the mounting ring 5 is welded on one side of the fixing block 15 and the mounting ring 5, and a second traction groove 18 is symmetrically provided on the surface of the guide rod 10, and the middle of the second traction groove 18 is inserted with a first traction block 9 welded on the mounting ring 5. When the operator pulls the threaded rod 11 to move, the operator first pulls the fixing block 15, and the fixing block 15 drives the threaded rod 11 to move through the loading groove 13, so that the threaded rod 11 moves in the through hole opened on the side of the mounting ring 5 penetrated by the threaded rod 11, and when the fixing block 15 moves, the fixing block 15 drives the guide rod 10 to move, so that the guide rod 10 is opened on the side of the mounting ring 5 penetrated by the guide rod 10 The guide rod 10 slides in the through hole opened on the side of the mounting ring 5 penetrated by the guide rod 10, so that the guide rod 10 pulls the fixed block 15, thereby improving the stability of the fixed block 15 driving the threaded rod 11 to move, and when the guide rod 10 slides in the through hole opened on the side of the mounting ring 5 penetrated by the guide rod 10, the second traction groove 18 symmetrically opened on the surface of the guide rod 10 slides on the surface of the first traction block 9 fixed on the inner wall of the mounting ring 5, so that the second traction groove 18 and the first traction block 9 restrict the guide rod 10, so that the guide rod 10 cannot fall off from the through hole opened on the side of the mounting ring 5 penetrated by the guide rod 10, thereby preventing the fixed block 15 from driving the threaded rod 11 to fall off from the surface of the mounting ring 5, and the operator is no longer required to repeatedly install the threaded rod 11 when replacing the gas valve body 3, thereby improving the usability of the operator.

[0028] In other embodiments, a baffle 14 is slidably connected to the opening of the threaded rod 11, and the ends of the baffle 14 are penetrated by the traction rod 12 fixed on the fixed block 15. Positioning grooves 20 are provided around the baffle 14, and the middle of the positioning grooves 20 is inserted with a positioning block 19 fixed on the fixed block 15. When the operator needs to take the threaded rod 11 out of the baffle 14, the operator first pulls the baffle 14 to make the baffle 14 slide in the notch opened at the opening of the loading slot 13, and the waist-shaped hole opened in the middle of the baffle 14 slides on the surface of the traction rod 12 set as a cylinder, so that the traction rod 12 pulls the baffle 14, and the stability of the movement of the baffle 14 is ensured, and when the baffle 14 moves, the baffle 14 drives the positioning groove 20 set as a semicircular groove to move on the surface of the positioning block 19 set as a semicircular protrusion. When the positioning groove 20 moves on the surface of the positioning block 19, the inner wall of the positioning groove 20 abuts against the positioning block 19 When the positioning block 19 is moved to the front end of the positioning block 19, the positioning block 19 is no longer squeezed by the surface of the baffle 14. The elastic deformation of the positioning block 19 is restored, and the positioning block 19 is inserted into the positioning groove 20. When the positioning block 19 is inserted into the positioning groove 20, the positioning block 19 and the positioning groove 20 increase the friction between the baffle 14 and the inner wall of the notch opened at the opening of the loading slot 13, so that the baffle 14 can stably block the opening of the loading slot 13, so that the baffle 14 restricts the threaded rod 11 to prevent the threaded rod 11 from moving out of the loading slot 13.

[0029] In other embodiments, first traction grooves 6 are provided at both side ends of the disc eaves 17, and the first traction grooves 6 are embedded with second traction blocks 21 welded on the collar 16, the first traction grooves 6 are configured as arc-shaped grooves, and the second traction blocks 21 are configured as arc-shaped blocks. When the collar 16 slides on the surface of the disc eaves 17, the collar 16 drives the second traction block 21 to move, so that the second traction block 21 configured as an arc-shaped block slides in the first traction groove 6 configured as an arc-shaped groove. By sliding the second traction block 21 in the first traction groove 6, the second traction block 21 pulls the first traction groove 6, thereby improving the stability of the collar 16 sliding on the surface of the disc eaves 17.
