Description

Technical Field

[0001] The utility model relates to the technical field of globe valves, and particularly relates to a pneumatic rubber-lined angle globe valve. Background Art

[0002] A globe valve, also known as a stop valve, belongs to a forced-sealing valve. Therefore, when the valve is closed, pressure must be applied to the valve flap to force the sealing surface not to leak. When the medium enters the valve from below the valve flap, the resistance that the operating force needs to overcome is the friction between the valve stem and the packing and the thrust generated by the pressure of the medium. The force to close the valve is greater than the force to open the valve, so the diameter of the valve stem needs to be large, otherwise the valve stem will be bent. A pneumatic rubber-lined angle globe valve is a type of globe valve. The size of a pneumatic rubber-lined angle globe valve is generally fixed. When the distance between two pipelines is greater than the length of the pneumatic rubber-lined angle globe valve or the positions of the two pipelines are offset, it is impossible to connect the pneumatic rubber-lined angle globe valve to the two pipelines. Content of the Utility Model

[0003] Aiming at the problems in the prior art, the utility model provides a pneumatic rubber-lined angle globe valve.

[0004] The technical solution adopted by the utility model to solve its technical problems is a pneumatic rubber-lined angle globe valve, which includes a pneumatic rubber-lined angle globe valve body and two connecting pieces. Expansion pipes are arranged on one side and below the pneumatic rubber-lined angle globe valve body. Flanges are fixed at both ends of the two expansion pipes. The flange near one end of the pneumatic rubber-lined angle globe valve body is connected to the pneumatic rubber-lined angle globe valve body through a bolt with a nut, and the flange near the other end of the pneumatic rubber-lined angle globe valve body is connected to the pneumatic rubber-lined angle globe valve body through a bolt with a nut. The connecting piece includes a support rod and a connecting bolt. Clamping blocks are integrally formed at both ends of the support rod. The clamping block near the pneumatic rubber-lined angle globe valve body is sleeved on the pneumatic rubber-lined angle globe valve body. Two screw holes adapted to the connecting bolt are formed on each of the two clamping blocks. A support member is arranged on one of the connecting pieces.

[0005] By adopting the above technical solution, the setting of the expansion pipe facilitates adjusting the position of the flange far from the pneumatic rubber-lined angle globe valve body according to the position of the pipeline. Even when the position of the pipeline is offset or the distance between the two pipelines is greater than the length of the pneumatic rubber-lined angle globe valve body, it is convenient to install the pneumatic rubber-lined angle globe valve body. After sleeving the two clamping blocks far from the pneumatic rubber-lined angle globe valve body on the two pipelines and tightening the connecting bolts, the support rod and the clamping blocks can support the pneumatic rubber-lined angle globe valve body, improving the stability of the pneumatic rubber-lined angle globe valve body.

[0006] Specifically, the support member includes a support seat and a locking bolt. One end of the support seat is provided with a card slot adapted to the support rod, the other end of the support seat is sleeved with a card holder, screw holes adapted to the locking bolt are formed on both sides of the card holder and the support seat, and four mounting holes arranged in a rectangular array are formed on one side of the card holder away from the support seat.

[0007] By adopting the above technical solution, when there is a wall or equipment beside the pneumatic rubber-lined angle stop valve body, pull out the card holder and tighten the locking bolts on both sides of the card holder, the position of the card holder can be adjusted according to the position of the wall surface or equipment, and the card holder is fixed on the wall surface or equipment by bolts. The support seat and the card holder can support the support rod, further improving the stability of the pneumatic rubber-lined angle stop valve body.

[0008] Specifically, protective pads are fixed in both of the clamping blocks.

[0009] By adopting the above technical solution, the setting of the protective pads can prevent the clamping blocks from scratching the pneumatic rubber-lined angle stop valve body.

[0010] Specifically, both of the telescopic tubes are metal telescopic tubes.

[0011] Specifically, a sealing pad is fixed on each flange.

[0012] By adopting the above technical solution, the setting of the sealing pads can improve the sealing performance between the flange and the pipeline and between the flange and the pneumatic rubber-lined angle stop valve body.

[0013] The beneficial effects of the present utility model:

[0014] (1) For the pneumatic rubber-lined angle stop valve described in the present utility model, the setting of the telescopic tubes facilitates adjusting the position of the flange away from the pneumatic rubber-lined angle stop valve body according to the position of the pipeline. Even when the position of the pipeline is offset or the distance between two pipelines is greater than the length of the pneumatic rubber-lined angle stop valve body, it is convenient for the installation of the pneumatic rubber-lined angle stop valve body. After sleeving the two clamping blocks away from the pneumatic rubber-lined angle stop valve body on the two pipelines and tightening the connecting bolts, the support rod and the clamping blocks can support the pneumatic rubber-lined angle stop valve body, improving the stability of the pneumatic rubber-lined angle stop valve body.
