Description
Technical field
The present invention relates to a kind of check-valves.
Background technology
In discharge pipe line, form " water in order to the fluid in pipeline when preventing termination of pumping or suddenly power-off refluxes suddenly
Hammer " equipment is damaged, check-valves is generally installed on pump outlet pipeline.Existing check-valves eliminates the effect of " water hammer "
The most undesirable, when termination of pumping or power-off suddenly, medium refluence duration is longer, holds very much in the case of pipeline pressure is relatively big
Easily water pump is caused damage.
Summary of the invention
The problem existed for above-mentioned prior art, the present invention provides a kind of check-valves, and this check-valves water is except " water hammer "
Satisfactory for result, the time that medium flows backwards when termination of pumping or power-off suddenly is short, can effectively reduce water pump and make because of " water hammer " effect
The infringement become.
To achieve these goals, the present invention provides a kind of check-valves, including valve body, flap and valve gap, valve body include into
The mouth of a river, 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, and valve gap is arranged with the axial of water inlet with paralleling, and described flap is positioned at valve pocket, described valve body
Valve seat it has been fixedly disposed in the inside of valve pocket, the angle of the axial Cheng Du of the axial and water inlet of described valve seat to degree, described
The upper end of flap and the left end lower hinge of valve gap, described flap coordinates with valve base sealing, described valve body valve on the right side of valve seat
Intracavity edge is provided with the protuberance that section is inverted V-shaped with being perpendicular to the axial restraint of water inlet, and the upper end of described protuberance is less than into water
The horizontal plane at the axis place of mouth.
In this technical scheme, by being provided with the protuberance in inverted V-shaped on the right side of valve seat, fortune can be stopped suddenly at water pump
Turning or in the case of suddenly power-off, make the water of refluence when flowing through protuberance, protuberance reduces the latus rectum of valve pocket, thus the water flow backwards
Speed can be accelerated, then swings to effect by protuberance right flank, makes the water noted act on flap right flank rapidly, and then permissible
Flap is made promptly to coordinate near valve seat and with valve base sealing.This check-valves 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 check-valves, described flap is made up of nitrile rubber.
Further, in order to improve the susceptiveness of flap action, the lower end upper surface of described flap has been fixedly disposed counterweight
Block, so can accelerate flap and stop suddenly at water pump or be adjacent to the time of valve seat in the case of power-off.
Further, the left surface of described protuberance can subtract in drainage procedure horizontal by 45 degree of angles, such water pump
Little protuberance is to the resistance formed in exiting water process, and the right flank of protuberance, so can be at medium horizontal by 135 degree of angles
During refluence, the flow direction to medium plays good guide effect, such that it is able to change the flow direction of medium and act rapidly on flap
Right flank.

Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of check-valves, including valve body 1, flap 2 and valve gap 3, valve body 1 includes water inlet 4, outlet 5
And the valve pocket 6 between water inlet 4 and outlet 5, water inlet 4 axially and outlet 5 axially coincident, described valve gap 3
Being tightly connected with valve body 1, valve gap 3 is arranged with the axial of water inlet 4 with paralleling, and 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, described valve seat 7 axially with water inlet 4 axial become 30 degree to 45 degree
Angle, the upper end of described flap 2 and the left end lower hinge of valve gap 3, described flap 2 coordinates with valve seat 7 sealing, described valve body
In 1 valve pocket 6 on the right side of valve seat 7, edge is provided with the protuberance 8 that section is inverted V-shaped with being perpendicular to the axial restraint of water inlet 4, described
The upper end of protuberance 8 is less than the horizontal plane at the axis place of water inlet 4.By being provided with the protuberance 8 in inverted V-shaped on the right side of valve seat 7,
Can shut down suddenly at water pump or in the case of power-off suddenly, make the water of refluence when flowing through protuberance 8, protuberance 8 reduces
The latus rectum of valve pocket 6, thus the water speed flow backwards can be accelerated, then by the effect of swinging to of protuberance 8 right flank, make the water noted rapid
Act on flap 2 right flank, and then flap 2 can be made promptly to coordinate near valve seat 7 sealing with valve seat 7.This check-valves energy
The effectively refluence time of medium in shortening 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 check-valves, described flap 2 is made up of nitrile rubber.
In order to improve the susceptiveness of flap 2 action, the lower end upper surface of described flap 2 has been fixedly disposed balancing weight 9.This
Sample can be accelerated flap 2 and stops suddenly at water pump or be adjacent to the time of valve seat 7 in the case of power-off.
The left surface of described protuberance 8 is horizontal by 45 degree of angles, and such water pump can reduce protuberance 8 in drainage procedure
To the resistance formed in exiting water process, the right flank of protuberance 8, horizontal by 135 degree of angles, so can flow backwards at medium
Time the flow direction of medium is played good guide effect, such that it is able to change the flow direction of medium and act rapidly on flap 2
Right flank.
