Abstract
The utility model discloses a can prevent water hammer's pressure pipeline, include: pipeline under pressure, ball valve, pneumatic valve and governing valve, ball valve, pneumatic valve and governing valve set up the department in pipeline under pressure, wherein, the ball valve sets up in the upper reaches of pneumatic valve, the governing valve sets up in the below of pneumatic valve, the quantity of governing valve is two and just establishes ties in the air inlet pipeline of the pneumatic valve of control. Through above -mentioned mode, the utility model discloses can prolong the time that the pneumatic valve valve was driven the valve and was closed the valve to restrict pressure rising suddenly or reduction and lead to the pipeline fracture.
Description
Technical field
The utility model is related to pipeline engineering field, more particularly to a kind of pressure piping that can prevent water hammer effect.
Background technology
In the prior art, the control mode of the pneumatic ball valve switching speed for being used in pressure piping：Enter in tracheae
Gas direction collocation one-way speed-regulating valve, the control to pneumatic ball valve folding speed is reached by controlling air inflow.But this scheme
Produced without water hammer when pneumatic operated valve can only be controlled to open, but water hammer scene is still had when pneumatic operated valve is closed and produced.
Utility model content
The utility model, can mainly solving the technical problems that provide a kind of pressure piping that can prevent water hammer effect
The time of extension pneumatic operated valve valve valve opening and pass valve, pipeline is caused to be broken to limit unexpected being raised and lowered of pressure.
In order to solve the above technical problems, the technical scheme that the utility model is used is：There is provided one kind can prevent water
Hammer the pressure piping of effect into shape, including：Pressure pipeline, ball valve, pneumatic operated valve and flow speed control valve, the ball valve, pneumatic operated valve and flow speed control valve set
It is placed at pressure pipeline, wherein, the ball valve is arranged at the upstream of pneumatic operated valve, and the flow speed control valve is arranged at the lower section of pneumatic operated valve,
The quantity of the flow speed control valve be two and be series at control pneumatic operated valve air inlet pipeline.
Preferably, gas supply contact is provided with below the flow speed control valve, for connecting external air source.
The beneficial effects of the utility model are：The utility model controls extension pneumatic operated valve valve valve opening and pass by flow speed control valve
The time of valve, cause pipeline to be broken to limit unexpected being raised and lowered of Fluid pressure, improve the service life of pressure piping.
Brief description of the drawings
Fig. 1 is that a kind of stereochemical structure of the preferred embodiment of pressure piping one that can prevent water hammer effect of the utility model is shown
It is intended to；
The mark of each part is as follows in accompanying drawing：1st, ball valve, 2, pneumatic operated valve, 3, flow speed control valve, 4, gas supply contact, 5, pressure
Pipeline.
Specific embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that advantage of the present utility model
Can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear and definite so as to be made to protection domain of the present utility model
Define.
Fig. 1 is referred to, the utility model embodiment includes：
A kind of pressure piping that can prevent water hammer effect, including：Pressure pipeline 5, ball valve 1, pneumatic operated valve 2 and flow speed control valve 3,
The ball valve 1, pneumatic operated valve 2 and flow speed control valve 3 are arranged at pressure pipeline 5, wherein, the ball valve 1 is arranged at the upper of pneumatic operated valve 2
Trip, the flow speed control valve 3 is arranged at the lower section of pneumatic operated valve 2, and the quantity of the flow speed control valve 3 is for two and is series at control pneumatic operated valve 2
Air inlet pipeline.
Further, the lower section of the flow speed control valve 3 is provided with gas supply contact 4, for connecting external air source.
The utility model is the design for avoiding pneumatic operated valve from producing water hammer to cause pipeline to be broken in switch.Including：Ball
Valve 1, the flow speed control valve 3, gas of pneumatic operated valve 2 supply contact 4.External air source supplies contact 4 and pneumatic operated valve 2 by flow speed control valve 3 with gas
Connection, to control the action of the valve switch of pneumatic operated valve 2, fluid is transmitted to startup ball valve 2 by ball valve 1.Opened when pneumatic operated valve 2 is needed
Or when closing, it is to avoid the valve folding excessive velocities of pneumatic operated valve 2, the size of air inflow is adjusted by adjusting flow speed control valve 3, and then control gas
The folding speed of the dynamic valve of valve 2, wherein two flow speed control valves 2 arranged in pairs or groups are series at the air inlet pipeline of control pneumatic operated valve 2, a control
Induction air flow ratio processed, another control exhaust flow rate, is reached to pneumatic ball valve folding speed by controlling air inflow/capacity
Control, it is to avoid pipeline is broken because of the water attack being mutated.
Embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited, it is every
The equivalent structure or equivalent flow conversion made using the utility model specification and accompanying drawing content, or be directly or indirectly used in
Other related technical fields, are similarly included in scope of patent protection of the present utility model.
