Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof valves, in particular to an explosion-proof valve with an adjusting function. Background Technique

[0002] An explosion-proof valve with an adjusting function is an important safety device, which is widely used in systems containing combustible gases. As a protective device to prevent the system from exploding due to overpressure, this explosion-proof valve combines the functions of adjustment and explosion protection, and can automatically adjust the pressure or release the excess pressure when the system pressure is abnormal, thus protecting the safety of equipment and personnel.

[0003] Explosion-proof valves are usually made of high-strength and corrosion-resistant alloy materials to ensure their long-term stability and reliability in harsh environments.

[0004] However, at present, the explosion-proof valve body lacks an effective automatic adjustment mechanism and cannot well automatically control the flow rate of the conveyed gas medium. Moreover, it lacks a simple and effective explosion-proof protection mechanism and cannot well monitor whether gas leakage occurs at the connection between the valve body and the pipeline body and send an alarm signal when leakage occurs, enabling the staff to better find the leakage location, thus having potential safety hazards. In view of this, we have proposed an explosion-proof valve with an adjusting function. Content of the Utility Model

[0005] The purpose of the utility model is to provide an explosion-proof valve with an adjusting function to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An explosion-proof valve with an adjusting function, including a pipeline body, on which an adjusting component is arranged, and the adjusting component includes:

A through slot is opened in the arc-shaped block, and multiple groups of the slots are provided. The tooth is clamped inside the slot.

[0010] Preferably, the rotating sleeve and the moving rod do not intersect with the protective cover and the cover door to prevent movement interference.

[0011] Preferably, the circular cross-sectional areas of the valve plate and the circular opening at the bottom end of the valve body are adapted to each other, so as to cut off the medium inside the pipeline body.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figure 1 - Figure 6The utility model provides a technical solution: an explosion-proof valve with an adjustment function, comprising a pipeline body 1 for conveying a gas medium.

[0027] In one embodiment of the utility model, an adjusting component 2 is provided on the pipeline body 1, and the adjusting component 2 includes a protective cover 21, a protective cover 21 is fixedly installed on the outside of the pipeline body 1, a cover door 22 is clamped on the protective cover 21, a valve body 23 is fixedly installed on the pipeline body 1, a valve stem 24 is rotatably installed inside the valve body 23, and a valve plate 25 is fixedly installed on the outside of the bottom end of the valve stem 24. In addition, the area size of the circular cross-section of the valve plate 25 and the circular opening at the bottom end of the valve body 23 are adapted, so that the medium inside the pipeline body 1 can be cut off, and the valve stem 24 top A rotating sleeve 26 is fixedly installed on the outer side of the end, an L-shaped frame 27 is fixedly installed on the top of the valve body 23, a servo asynchronous motor 28 is fixedly installed on the top of the L-shaped frame 27, and a rotating shaft 29 is fixedly installed on the output end of the bottom end of the servo asynchronous motor 28. The bottom of the rotating shaft 29 is fixedly connected to the top of the rotating sleeve 26, and cooperates with the protective cover 21 and the cover door 22 to better protect the valve body 23. When the servo asynchronous motor 28 on the L-shaped frame 27 is started, the rotating shaft 29 is rotated, so that the rotating sleeve 26 rotates synchronously, so that the valve stem 24 drives the valve plate 25 to rotate, and the rotating sleeve 26 A rotating rod 210 is fixedly installed inside, and a moving rod 211 is rotatably installed outside the rotating rod 210. In addition, the rotating sleeve 26 and the moving rod 211 do not intersect with the protective cover 21 and the cover door 22 to prevent movement interference. A servo hydraulic rod 212 is hingedly installed at one end of the rotating sleeve 26, and the piston end of the other end of the servo hydraulic rod 212 is hingedly installed on the top of the moving rod 211. A reset spring 213 is fixedly installed between the rotating sleeve 26 and the moving rod 211, and cooperates with the servo hydraulic rod 212 to make the moving rod 211 rotate outside the rotating rod 210, and reset at the same time. The spring 213 is deformed, and a latch tooth 214 is fixedly installed on the moving rod 211. An arc block 215 is fixedly installed on the outer side of the top of the valve body 23. A penetrating latch groove 216 is opened on the arc block 215. There are multiple groups of latch grooves 216. The latch tooth 214 is latched in the inside of the latch groove 216, so that the latch tooth 214 can be selectively latched into different latch grooves 216 in cooperation with the arc block 215, so that the valve plate 25 can be better fixed at different positions, and then the explosion-proof valve body can be better adjusted to control the flow rate of the transported gas medium.

[0028] In an embodiment of the present utility model, a protection component 3 is arranged inside the protection cover 21. The protection component 3 includes a fixing plate 31. The fixing plate 31 is fixedly installed on the inner wall of the protection cover 21. The top of the fixing plate 31 is fixedly installed with a rectangular box 32. Through holes 33 are formed in the side wall of the rectangular box 32. There are multiple groups of through holes 33, and the multiple groups of through holes 33 are linearly arranged at equal intervals. In addition, a rectangular plate 34 is clamped inside the rectangular box 32. Further, when gas leakage occurs at the connection between the valve body 23 and the pipeline body 1, the gas density inside the protection cover 21 increases. Thus, in cooperation with the fixing plate 31 and the rectangular box 32, the gas enters between the rectangular plate 34 and the rectangular box 32 through the through holes 33. An airbag 35 is arranged inside the rectangular box 32, so that the airbag 35 is squeezed and deformed. A sliding rod 36 is fixedly installed on the outside of the airbag 35. The sliding rod 36 penetrates through the rectangular plate 34. In addition, a fixing seat 37 is fixedly installed on the inner bottom surface of the rectangular box 32. The sliding rod 36 is slidably installed inside the top end of the fixing seat 37, so that the sliding rod 36 slides inside the fixing seat 37. A controller 38 is fixedly installed at the bottom of the valve body 23. The controller 38 is electrically connected to an external warning component (the controller 38 can emit an alarm signal). One end of the servo asynchronous motor 28 facing the sliding rod 36 is provided with a push-button switch 39. After the push-button switch 39 is pressed, it needs to be manually pressed again to pop out. Thus, in cooperation with the controller 38 and the push-button switch 39, an alarm signal is emitted, and the safety of the explosion-proof valve body can be better improved.

[0029] Working principle: In cooperation with the protection cover 21 and the cover door 22, the valve body 23 is better protected. When the servo asynchronous motor 28 on the L-shaped frame 27 is started, the rotating shaft 29 rotates, so that the rotating sleeve 26 rotates synchronously, so that the valve rod 24 drives the valve plate 25 to rotate. At the same time, in cooperation with the servo hydraulic rod 212, the moving rod 211 rotates outside the rotating rod 210, and the reset spring 213 deforms. Thus, in cooperation with the arc-shaped block 215, the cogs 214 are selectively engaged into different card slots 216, so that the valve plate 25 can be better fixed at different positions, and the explosion-proof valve body can be better adjusted to control the flow rate of the conveyed gas medium. Further, when gas leakage occurs at the connection between the valve body 23 and the pipeline body 1, the gas density inside the protection cover 21 increases. Thus, in cooperation with the fixing plate 31 and the rectangular box 32, the gas enters between the rectangular plate 34 and the rectangular box 32 through the through holes 33, so that the airbag 35 is squeezed and deformed, so that the sliding rod 36 slides inside the fixing seat 37, and in cooperation with the controller 38 and the push-button switch 39, an alarm signal is emitted, and the safety of the explosion-proof valve body can be better improved.

[0030] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements that do not depart from the spirit of the present utility model are within the protection scope of the present utility model.
