Description
Technical field
The present invention relates 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 add the pilot-operated type structure type of pilot valve 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 step-down that sluices, it is impossible to which realization is opened immediately in real time, there is water
Break up bad risk.Also use spring direct action type, run it 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 cannot almost be produced greatly.
The content of the invention
The technical problems to be solved by the invention are to provide one kind and adapt to heavy caliber, high pressure operating mode, occur in water attack
When can rapidly react in real time, be active in one's movements, ensure pipe network system safely and effectively operation balanced type Direct Action Type water attack release valve.
In order to solve the above-mentioned technical problem, the balanced type Direct Action Type water attack release valve that the present invention is provided, including valve body and valve
Lid, valve seat is provided between the entrance point and the port of export of described valve body, equipped with set on the valve seat described in the described valve body
Cylinder, described sleeve is positioned by described bonnet, is offered on the side wall of described valve seat one end on described sleeve
The described entrance point of connection and the flowing hole of the port of export, are provided with sealing corresponding with the entrance point of described valve body in described sleeve
Adjustment barrel, described flowing hole is connected or blocked when described adjustment barrel moves up and down to connect or block described entrance point
And the port of export, described bonnet is equipped with piston cylinder, piston is provided with described piston cylinder by the inner side of described valve body, described
Adjustment barrel is connected by valve rod with described piston, and one end of communicating pipe is connected with described valve rod, and the other end passes through described
Bonnet is reached and be connected with the outside of bonnet a buffer unit.
The indicating arm through described buffer unit is installed on described communicating pipe top.
The structure of described buffer unit is:Spring cylinder is provided with the outside of bonnet, be provided with described spring cylinder spring base,
Spring cup and the spring between described spring base and described spring cup, described spring base be arranged on through
On the described communicating pipe of described bonnet, the top of described spring cylinder is provided with regulation screwed pipe, and described regulation screwed pipe is passed through
Described spring cylinder one end contacts with described spring cup, and the other end exposes described spring cylinder and is provided with lock nut.
The side wall of described communicating pipe is being provided with the first passage, is being close to described spring cup near described piston end
One end is provided with the second passage, described piston with upper plenum a by described communicating pipe and its it is set described in first lead to
Stomata and the second described passage are connected with described spring cylinder inner spring seat with upper plenum b.
Sealing ring is provided between described spring base and the inwall of described spring cylinder.
Cavity c below the above-described spring base of described bonnet is opened by described spring cylinder by described bonnet end
If the 3rd passage be connected with a check valve, be connected with a regulating valve needle-valve by the 4th passage, described spring
Cavity b more than seat is communicated by the 5th passage on described spring cylinder top with air.
Described flowing hole is V-arrangement flowing hole.
The entrance point of described valve body is set to the back taper runner that an angle is R, is more than the internal diameter of described sleeve
Valve nominal dimension.
Described adjustment barrel, piston cylinder and spring cylinder are on the same central axis of described valve body middle chamber.
Described valve body uses angie type, or is designed as through type.
Using the balanced type Direct Action Type water attack release valve of above-mentioned technical proposal, opened and closed by piston driving adjustment barrel and run,
Piston is directly contacted towards valve body-side with medium, and piston is communicated above by communicating pipe and spring cylinder epicoele with air, and spring passes through
Communicating pipe is directly acted on piston, i.e., spring pressure is directly compared by piston with pressure medium, and spring force can be by regulation
Screwed pipe sets, once pressure exceedes spring setting value, piston passes through to be moved on communicating pipe push the spring seat, and spring is rapid compression,
The check valve that cavity c following with spring base is connected is opened, and air quickly sucks cavity c, and piston is driven in adjustment barrel synchronization simultaneously
Remove and open, valve event is sensitive rapidly.Spring push the spring seat and adjustment barrel are descending after the completion of pressure release, with the following cavity of spring base
C connected closed check valve, air realizes valve slowly closing, prevents from itself from producing via the controllable slow discharge of metering pin valve
It is raw to close valve water hammer.
Because using columnar adjustment barrel, used as opening and closing element, without blind plate thrust, running resistance is small, opens for cylindrical shape adjustment barrel
Close torque small, valve event can be driven with spring force using less piston area, compared with prior art, both with straight
Dynamic formula sensitive and retain pilot-operated type and can make high pressure, bigbore feature.
Rotating regulation screwed pipe can adjust the thrust of spring by spring cup, be locked with lock nut after reaching setting value.
Communicating pipe, top was provided with the indicating arm through regulation screwed pipe, and described indicating arm is used 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 smaller amount of movement and the smaller decrement of spring, the adjustable of valve pressure release value can be effectively increased
Scope, and extend the service life of spring.
In sum, the present invention is that one kind adapts to heavy caliber, high pressure operating mode, can be opened rapidly in real time when water attack occurs
Open, pressure release finish after can steady controllable Slow Close, be active in one's movements, operating pressure is adjustable, can ensure that pipe network system is safely and effectively run
Balanced type Direct Action Type water attack release valve.
