Abstract
The utility model provides a fast closed check valve, includes valve body, valve clack and valve gap, the valve body include water inlet, delivery port and be located the water inlet and the delivery port between the valve pocket, the axial of water inlet and the coincidence of the axial of delivery port, the valve gap is connected with body seals, and the valve gap sets up with the axial of water inlet with paralleling, the valve clack is located the valve pocket, the valve body is provided with the disk seat in the inside of valve pocket regularly, the axial of disk seat and the contained angle of the axial cheng du of water inlet to the degree, the upper end of valve clack is articulated with the left end lower part of valve gap, the cooperation of valve clack and valve seat seal, the right side lower part of valve clack with the inner arm on valve body right side upper portion passes through hydraulic damper and articulates. This fast closed check valve water removes the effect ideal of " water hammer ", in the termination of pumping or when cutting off the power supply suddenly the time of medium refluence short, can reduce the water pump effectively and act on the harm that causes because of " water hammer ".
Description
Technical field
This utility model is related to a kind of speed closed type check valve.
Background technology
In discharge pipe line, for " the water preventing the fluid in pipeline when termination of pumping or unexpected power-off from flowing back suddenly and being formed
Hammer " damages to equipment, installs fast closed type check valve generally on pump outlet pipeline.Existing speed closed type check valve disappears
Except the effect of " water hammer " is undesirable, in termination of pumping or unexpected power-off, medium refluence duration is longer, larger in pipeline pressure
In the case of be easy to water pump is caused damage.
Content of the invention
The problem existing for above-mentioned prior art, this utility model provides a kind of speed closed type check valve, and this fast enclosed is stopped
Return the effect ideal that valve water removes " water hammer ", the time that medium flows backwards in termination of pumping or unexpected power-off is short, can effectively reduce water pump
The infringement causing because of " water hammer " effect.
To achieve these goals, this utility model provides a kind of speed closed type check valve, including valve body, flap and valve gap,
Valve body includes water inlet, outlet and the valve pocket being located between water inlet and outlet, the axial direction of water inlet and the axle of outlet
To coincidence, described valve gap is connected with valve seal, and valve gap is arranged with the axial direction of water inlet with paralleling, and described flap is located at valve pocket
Interior, described valve body has been fixedly disposed valve seat in the inside of valve pocket, and the axial Cheng Du of the axial direction of described valve seat and water inlet is to degree
Angle, the left end lower hinge of the upper end of described flap and valve gap, described flap is coordinated with valve base sealing, under the right side of flap
Portion is hinged by hydraulic damper with the inner arm of described valve body right upper portion.
In this technical scheme, hindered by hydraulic pressure with the inner arm of described valve body right upper portion by the lower right side making flap
Buddhist nun's device is hinged, can water pump shut down suddenly or unexpected power-off in the case of, hydraulic damper is simultaneously fast with the water of refluence
Act on the right flank of flap fastly, and then flap can be made promptly to coordinate near valve seat and with valve base sealing.This speed is closed
Formula check-valves can effectively shorten the refluence time of medium in valve pocket, thus can effectively reduce water pump and make because " water hammer " acts on
The infringement becoming.
Further, the weight overall in order to reduce this fast closed type check valve, described flap is made up of nitrile rubber.
Further, in order to improve the susceptiveness of flap action, the top of described flap is provided with cavity.Flap so can be accelerated
It is adjacent to the time of valve seat in the case of water pump stopping suddenly or power-off.
Brief description
Fig. 1 is structural representation of the present utility model.
In figure: 1, valve body, 2, flap, 3, valve gap, 4, water inlet, 5, outlet, 6, valve pocket, 7, valve seat, 8, hydraulic damping
Device, 9, cavity.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of speed closed type check valve, including valve body 1, flap 2 and valve gap 3, valve body 1 includes water inlet 4, goes out
The mouth of a river 5 and the valve pocket 6 being located between water inlet 4 and outlet 5, the axial direction of water inlet 4 is axially coincident with outlet 5, described
Valve gap 3 is tightly connected with valve body 1, and valve gap 3 is arranged with the axial direction of water inlet 4 with paralleling, and described flap 2 is located in valve pocket 6, institute
State valve body 1 and be fixedly disposed valve seat 7 in the inside of valve pocket 6, the axial direction of described valve seat 7 becomes 45 degree to arrive with the axial direction of water inlet 4
60 degree of angle, the upper end of described flap 2 and the left end lower hinge of valve gap 3, described flap 2 and valve seat 7 sealing cooperation, flap
2 lower right side is hinged by hydraulic damper 8 with the inner arm of described valve body 1 right upper portion.
By making the lower right side of flap 2 and the inner arm of described valve body 1 right upper portion hinged by hydraulic damper 8, can
With water pump shut down suddenly or unexpected power-off in the case of, hydraulic damper 8 is rapidly acted on the water of refluence simultaneously
On the right flank of flap 2, so can make flap 2 promptly near valve seat 7 and close with valve seat 7 envelopes cooperation.This fast enclosed non-return
Valve can effectively shorten the refluence time of medium in valve pocket, thus can effectively reduce the damage that water pump causes because " water hammer " acts on
Evil.
The weight overall in order to reduce this fast closed type check valve, described flap 2 is made up of nitrile rubber.
In order to improve the susceptiveness of flap 2 action, the top of described flap 2 is provided with cavity 9.Flap 2 so can be accelerated exist
It is adjacent to the time of valve seat 7 in the case of water pump stopping suddenly or power-off.
