Problems solved by technology

[0002] In the known technology, the opening and closing of the valve usually adopts a spiral lift, which has many exposed parts, and is easy to rust and get stuck in the harsh working environment.
Moreover, it relies on manual operation, which is laborious to lift, and it is not easy to realize long-distance remote control operation.
Chinese patent ZL93233727.9 discloses a technical scheme of "no leakage and labor-saving logistics switch valve", which adopts a fluid channel on the valve body, which makes it difficult to realize the processing technology of the valve body, and there are as many as 4 micro-adjustment control valves. Not only makes the operation too complicated, but also the corresponding valve mechanism is complicated, which affects the reliability of the mechanism operation
At the same time, there are many through holes in the valve body, which is easy to cause leakage.

Embodiment Construction

[0009] The present invention will be specifically described below in conjunction with the accompanying drawings. The examples are used to illustrate the present invention, but not to limit the present invention in any way.

[0010] The controllable automatic on-off valve includes a valve body (14) and a valve cover (13), and the position corresponding to the valve through hole (15) in the valve body (14) is provided with a piston consisting of an upper piston (4) and a lower piston (2). Piston group, the upper piston (4) and the lower piston (2) are coaxially connected by the valve stem (3), the valve stem (3) is provided with a hollow fluid channel, and the upper end of the hollow fluid channel is equipped with a diversion tube (5), and the diversion The other end of the pipe (5) passes through the bonnet (13) and is closed by the control valve (9) to open the valve through hole or communicate with the piston chamber (12) through the fluid channel of the control valve (9) and...

Abstract

The invention is a kind of controllable automatic switch valve, which includes a valve body, a cover, the character lies in: there set a piston group made up of a upper piston and a subjacent piston on position correspondent to the valve aperture, the upper piston and the subjacent piston are connected coaxially with valve pole, there has a hollow flow channel in the valve pole, there covers a flow guiding pipe on top of the hollow flow channel, another end of the flow guiding penetrates the valve cover and being closed through the control valve, and start the valve hole or connects to the piston cavity through the control valve flow channel, and pushes the piston group to close the valve hole.

Description

Technical field: [0001] The invention belongs to a valve, and in particular relates to a controllable automatic on-off valve by fluid action. Background technique: [0002] In the known technology, the opening and closing of the valve usually adopts a spiral lift, which has many exposed parts, and is prone to rust and stagnation under the harsh working environment. And it depends on manual operation, it is laborious to lift, and it is difficult to realize long-distance remote control operation. Chinese patent ZL93233727.9 discloses a technical scheme of "no leakage and labor-saving logistics switch valve", which adopts a fluid channel on the valve body, which makes it difficult to realize the processing technology of the valve body, and there are as many as 4 micro-adjustment control valves. Not only makes the operation too complicated, but also the corresponding valve mechanism is complicated, which affects the operational reliability of the mechanism. At the same time, t...
