Technical field
The utility model is related to a kind of valve, the water attack direct acting Drainage valve of more particularly to a kind of balancing sleeve structure.
Background technology
In pipe network system operation, there is manifold pressure suddenly change and produce water in particularly long range pipe network system
The risk of hammer, water hammer has destructive power to pipe network equipment, and spread speed is quickly, close to sound wave in water transmission speed.
In the prior art, for pipe network water attack protection valve more than the pilot-operated type structure type of pilot valve added using main valve, pass through in operation
First moving for pilot valve drives the rear dynamic of main valve, so as to realize that main valve opens the decompression that sluices, it is impossible to which realization is opened immediately in real time, there is water
Break up bad risk.Also spring direct action type is used, operation is sensitive, be swift in response, but because spring is to directly act on valve
Plate, is only adapted to the operating mode that pressure is relatively low, bore is little, when system pressure is high, valve aperture is big, it is necessary to many sturdy bullets
Spring, structure bulky, and many spring linkages, performance-adjustable are poor, and bore more then can not almost be produced greatly.
Utility model content
Technical problem to be solved in the utility model is to provide one kind and adapts to heavy caliber, high pressure operating mode, in water attack
It can rapidly react, be active in one's movements in real time during generation, ensureing that the balanced type Direct Action Type water attack that pipe network system is safely and effectively run is released
Valve.
In order to solve the above-mentioned technical problem, the balanced type Direct Action Type water attack release valve that the utility model is provided, including valve body
And bonnet, it is provided with valve seat, the valve seat described in described valve body and fills between the entrance point and the port of export of described valve body

It is raw to close valve water hammer.
Because using columnar adjustment barrel, as opening and closing element, cylindrical shape adjustment barrel is without blind plate thrust, and running resistance is small, opens
Close torque small, valve event can be driven using less piston area and spring force, compared with prior art, both with straight
Dynamic formula sensitive and retain pilot-operated type and can make high pressure, bigbore feature.
The thrust of spring can be adjusted by spring cup by rotating regulation screwed pipe, reached after setting value and to be locked with lock nut.
Communicating pipe, top was provided with the indicating arm through regulation screwed pipe, and described indicating arm is to show valve opening.
Meanwhile, the V-arrangement flowing hole on sleeve makes valve opening linear with flow, valve is flowed in operation is opened and closed
Amount is steady, it is to avoid " chatter " phenomenon of relief valve.
The back taper runner that one angle is R is set to by valve body import end, expands lumen flow channels, adjustment barrel is existed
Full runner area of passage is just can reach under the smaller smaller decrement of amount of movement and spring, the adjustable of valve pressure release value can be effectively increased
Scope, and extend the service life of spring.
In summary, the utility model is that one kind adapts to heavy caliber, high pressure operating mode, can be fast in real time when water attack occurs
The steady controllable Slow Close of energy, is active in one's movements, operating pressure is adjustable, can ensure that pipe network system is safe and effective after speed unlatching, pressure release are finished
The balanced type Direct Action Type water attack release valve of operation.
