Abstract
The utility model relates to the technical field of valves, in particular to a muffle check valve, comprising a valve body, a seal ring, a valve flap, a valve rod, a sprig and a valve cover. The valve flap separates the valve body into a first cavity and a second cavity, the first cavity is provided with a first cavity wall, the second cavity is provided with a second cavity wall, and a pressure sensor and a decompression valve are arranged on the valve body. The muffle check valve, being simple in structure and convenient to use, can detect the pressure in the valve based on the pressure sensor, if the pressure is high, the decompression valve can be rotated to perform decompression, so that personal safety of maintenance personnel during the maintenance can be guaranteed; and moreover, fast maintenance can be carried out, maintenance difficulty is reduced, and work efficiency is improved.
Description
Technical field
The utility model relates to valve technology field, especially a kind of damping check valve.
Background technique
Damping check valve refers to and relies on medium itself to flow and automatic open and close flap, is used for preventing the valve that medium flows backwards, and claims again check valve, one-way valve, damping check valve reflux valve and back pressure valve.Safety check belongs to a kind of automatic valve, and its Main Function is to prevent that medium from flowing backwards, preventing the reversion of pump and drive motor, and the releasing of vessel media.Safety check also can be used for to pressure wherein may rise to exceed system press auxiliary system provide on the pipeline of supply.Safety check mainly can be divided into Swing check valve (according to center of gravity rotation) and Lift check valve (moving along axis).
But, common damping check valve, in the time of maintenance, often because valve fluid pressure is excessive, while opening, solution causes liquid to spray, and particularly some corrosive liquids, easily cause huge injury to personal safety.
Model utility content
The technical problems to be solved in the utility model is: in order to overcome damping check valve common in prior art, in when maintenance often because valve fluid pressure is excessive, while opening, solution causes liquid to spray, particularly some corrosive liquids, easily cause the problem of huge injury to personal safety, the utility model provides a kind of damping check valve, can predict valve internal pressure according to pressure transducer, if pressure is large, can carry out pressure release by rotation Decompression valves, in the time of maintenance, just can guarantee maintenance man's personal safety, and can carry out rapid-maintenance, reduce maintenance, improve working efficiency.
The utility model solves the technological scheme that its technical problem adopts: a kind of damping check valve, comprise valve body, flap, valve rod, spring and valve gap, body cavity is divided into the first cavity and the second cavity by described flap, described the first cavity is provided with the first cavity chamber wall, described the second cavity is provided with the second cavity chamber wall, and described in it, valve body is provided with
Pressure transducer, described pressure transducer is arranged in the first cavity through the second cavity chamber wall, the second cavity and the first cavity chamber wall successively, is used for detecting the hydraulic pressure in the first cavity, and
Decompression valves, described Decompression valves comprises the screw rod that screw thread is fixedly connected on guide sleeve on the second cavity chamber wall, is arranged in the cock body on the first cavity chamber wall and is fixedly connected with cock body through guide sleeve.
Optionally, between described valve body and flap, be provided with seal ring.
Optionally, between described guide sleeve and the second cavity chamber wall, be provided with seal ring.
Optionally, between described cock body and the first cavity chamber wall, be provided with seal ring.
Optionally, described screw rod one end is fixedly connected with rotating handles.
The beneficial effects of the utility model are: a kind of damping check valve that the utility model provides, simple in structure, easy to use, can predict valve internal pressure according to pressure transducer, if pressure is large, can carry out pressure release by rotation Decompression valves, in the time of maintenance, just can guarantee maintenance man's personal safety, and can carry out rapid-maintenance, reduce maintenance, improve working efficiency.
