Abstract
The invention discloses a quick closing check valve. The quick closing check valve comprises a valve body, a valve clack and a valve cover, wherein the valve body comprises a water inlet, a water outlet and a valve cavity positioned between the water inlet and the water outlet; the axial direction of the water inlet overlaps with the axial direction of the water outlet; the valve cover is hermetically connected with the valve body; the valve cover is arranged, parallel to the axial direction of the water inlet; the valve clack is positioned inside the valve cavity; valve seats are fixedly arranged in the positions, in the valve cavity, of the valve body; the axial direction of the valve seats and the axial direction of the water inlet form included angles from 45 degrees to 60 degrees; the upper end of the valve clack is hinged to the lower part of the left end of the valve cover; the valve clack is in seal fit with the valve seats; and the lower part of the right side of the valve clack is hinged to an inner arm at the upper part of the right side of the valve body through a hydraulic damper. According to the quick closing check valve, an ideal effect of a water hammer is achieved, the reverse flowing time of a medium is short during pump stop or sudden outage, and the damage to a water pump due to the action of the water hammer can be effectively reduced.
Description
Technical field
The present invention relates to a kind of speed closed type check valve.
Background technology
In discharge pipe line, form " water hammer " in order to the fluid in pipeline when preventing termination of pumping or suddenly power-off refluxes suddenly equipment is damaged, speed closed type check valve is generally installed on pump outlet pipeline.The effect that existing speed closed type check valve eliminates " water hammer " is undesirable, and when termination of pumping or power-off suddenly, medium refluence duration is longer, is easy to cause damage water pump in the case of pipeline pressure is relatively big.
Summary of the invention
The problem existed for above-mentioned prior art, the present invention provides a kind of speed closed type check valve, this speed closed type check valve water is satisfactory for result except " water hammer ", and the time that medium flows backwards when termination of pumping or power-off suddenly is short, can effectively reduce the infringement that water pump causes because of " water hammer " effect.
To achieve these goals, the present invention 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 between water inlet and outlet, water inlet axially and outlet axially coincident, described valve gap is connected with valve seal, valve gap is arranged with the axial of water inlet with paralleling, described flap is positioned at valve pocket, described valve body has been fixedly disposed valve seat in the inside of valve pocket, the axial Cheng Du of the axial and water inlet of described valve seat is to the angle of degree, the upper end of described flap and the left end lower hinge of valve gap, described flap coordinates with valve base sealing, the lower right side of flap and the inner arm of described valve body right upper portion are hinged by hydraulic damper.
In this technical scheme, by making the lower right side of flap and the inner arm of described valve body right upper portion hinged by hydraulic damper, suddenly can shut down or in the case of power-off suddenly at water pump, the water of hydraulic damper and refluence acts on the right flank of flap simultaneously rapidly, and then flap can be made promptly to coordinate near valve seat and with valve base sealing.This speed closed type check valve can effectively shorten the refluence time of medium in valve pocket, thus can effectively reduce the infringement that water pump causes because of " water hammer " effect.
Further, the weight overall in order to reduce this speed 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.So can accelerate flap stop suddenly at water pump or in the case of power-off, be adjacent to the time of valve seat.

Detailed description of the invention
The invention will be further described 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, outlet 5 and the valve pocket between water inlet 4 and outlet 56, water inlet 4 axially and outlet 5 axially coincident, described valve gap 3 is tightly connected with valve body 1, valve gap 3 is arranged with the axial of water inlet 4 with paralleling, described flap 2 is positioned at valve pocket 6, described valve body 1 has been fixedly disposed valve seat 7 in the inside of valve pocket 6, the angle axially becoming 45 degree to 60 degree of the axial and water inlet 4 of described valve seat 7, the upper end of described flap 2 and the left end lower hinge of valve gap 3, described flap 2 seals with valve seat 7 and coordinates, the lower right side of flap 2 and the inner arm of described valve body 1 right upper portion are hinged by hydraulic damper 8.
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, suddenly can shut down or in the case of power-off suddenly at water pump, hydraulic damper 8 acts on the right flank of flap 2 with the water flow backwards simultaneously rapidly, and then flap 2 can be made promptly to coordinate near valve seat 77 envelopes close with valve seat.This speed closed type check valve can effectively shorten the refluence time of medium in valve pocket, thus can effectively reduce the infringement that water pump causes because of " water hammer " effect.
The weight overall in order to reduce this speed 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.So can accelerate flap 2 stop suddenly at water pump or in the case of power-off, be adjacent to the time of valve seat 7.
