Abstract
The utility model relates to an anti-'water attack' valve, wherein a 'water attack' phenomenon can be generated when a valve is closed under circumstances of practical application, and 'water attack' can damage pipe network and equipment. The utility model aims at providing a valve which can prevent 'water attack', and comprises a valve, a pressure release valve body, a plane valve flap, a spring, a spring seat, an adjusting screw, a pressure-bearing pipe and a back-pressure pipe. The utility model is characterized in that a water inlet cavity of the valve is connected with a water inlet of the pressure release valve body by the bearing pipe, and a water outlet cavity of the valve is connected with a water outlet of the pressure release valve body by the back-pressure body. When the valve is closed, pressure of flow bodies in the water inlet cavity of the valve is suddenly boosted, and the boosted pressure gets into the water outlet cavity of the valve through the bearing pipe, the pressure release valve body and the back-pressure pipe, thereby leading water-attack pressure to be released by pass, and eliminating the 'water-attack' phenomenon.
Description
Technical field: the utility model relates to a kind of anti-" water attack " valve that uses in industrial pipe network.
Background technique: under some situation of practical application, work as valve closing, the pipeline inner fluid is ended suddenly, fluid is under the effect of coherence power, flap in the valve is formed water attack, and moment produces the huge sound and vibration, and " water attack " can cause damage to pipe network equipment.
Summary of the invention: the utility model will provide a kind of valve that can eliminate " water attack " phenomenon exactly.It is made up of valve, release of pressure valve body, plane flap, spring, spring seat, adjusting screw, pressure-bearing pipe, back pressure pipe.It is characterized in that the valve water-inlet cavity is connected with release of pressure valve body water intake by the pressure-bearing pipe, the valve water chamber is connected with release of pressure valve body water outlet by the back pressure pipe, and when the moment of valve closing, the hydrodynamic pressure in the valve water-inlet cavity raises suddenly under the effect of inertial force.This elevated pressure opens the plane flap in the release of pressure valve body through the pressure-bearing pipe, obtains being close to road release thereby make surge pressure enter the valve water chamber by the back pressure pipe.Eliminated " water attack " phenomenon.
Description of drawings: accompanying drawing is the utility model partial structurtes generalized sections.
Embodiment: as shown in drawings, pressure-bearing pipe (11) one ends are connected with water-inlet cavity (12), the other end is connected with the water intake (10) of release of pressure valve body (5), back pressure pipe (3) one ends are connected with water chamber (2), the other end is connected with the water outlet (4) of release of pressure valve body (5), spring (8) left end is connected with plane flap (9), and right-hand member is connected with spring seat (7).The elastic force of adjusting screw (6) Regulation spring (8) is to adapt to different surge pressures.
