Embodiment

[0020] like figure 1 As shown, a pneumatic pipe pinch valve, the main components include three parts: valve body, clamping assembly and pneumatic assembly.

[0021] The valve body is composed of upper valve body 10 and lower valve body 3, which are connected by bolt II 31 and nut V33. There is also a washer IV here to enhance the locking torque of the upper and lower valve bodies. This detachable The split design makes the maintenance of the valve more convenient. The inside of the valve body is provided with a sleeve 6 as a medium flow channel.

[0022] The clamping assembly includes a small valve stem 11, a large valve stem 12, a bracket 8, a pull rod 4, an upper pressing rod 7 and a lower pressing rod 1. The small valve stem 11 is movably installed in the large valve stem 12, and is connected with the large valve stem. Rod 12 constitutes a threaded pair to facilitate the relative movement of the two. The upper pressing rod 7 is arranged at the lower end of the small valv...

Abstract

The invention relates to a pneumatic tube clamping valve which comprises a valve body, a pneumatic component and a clamping component. A sleeve used as a medium flowing channel is arranged in the valve body, the pneumatic component is arranged on the valve body, the clamping component is arranged in the valve body and is connected with the pneumatic component, and the clamping component is controlled by the pneumatic component to clamp or loosen the sleeve. Compared with the prior art, the pneumatic tube clamping valve has the advantages of being long in service life, low in cost, convenient to maintain and the like.

Description

technical field [0001] The invention relates to a valve, in particular to a pneumatic pipe pinch valve. Background technique [0002] Pneumatic pipe pinch valve is suitable for conveying ore slurry, abrasive material, fine granular dry and wet dust slurry, etc., on the pipeline of general corrosive medium with working temperature ≤ 80 ℃, and controls the opening and closing mechanism of medium flow. At present, domestic and foreign control devices for conveying granular slurry and chemical media in low-pressure pipelines have traditionally basically adopted wear-resistant metal and PTFE sealing methods. This method has a short service life and high cost. Contents of the invention [0003] The object of the present invention is to provide a pneumatic pipe pinch valve with long service life, low cost and convenient maintenance in order to overcome the above-mentioned defects in the prior art. [0004] The purpose of the present invention can be achieved through the followin...
