Description
Technical field
The utility model is related to valve technology fields, and damping check valve is buffered more particularly, to a kind of liquid-ring type.
Background technology
In the prior art, damping check valve is typically that spring member is arranged on flap.After valve closing, water flow velocity
Degree becomes smaller, and water reduces the active force of flap, and spring member is more than water to the active force of flap, spring structure to the active force of flap
Part starts to restore deformation, drives flap to move together during spring member restores deformation.Due to the resistance of return water in valve body
Force effect is restored the starting stage of deformation in spring member, and the speed that spring member restores deformation is low, and the speed of flap is low；
After the resistance of return water gradually decreases, spring member meeting quick traction flap valve body abuts valve body due to inertia in flap
Moment can cause larger water attack sound, or even there are the risks of valve body damage.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of liquid-ring type buffering damping check valve.
In order to solve the above technical problems, the technical solution adopted in the utility model is：A kind of liquid-ring type buffering noise elimination non-return
Valve, including valve body, flap component and spring, the flap component are arranged in the inner cavity of the valve body, it is characterised in that：It is described
Flap component includes that the water inlet of valve body described in the first sliding axle, flap and the second sliding axle of integrally connected is provided with
One valve seat；It is provided with leading truck on first valve seat, the first pilot hole is provided in the middle part of the leading truck, described first slides
Moving axis is arranged in first pilot hole；The water outlet of the valve body is provided with the second leading truck, second leading truck
Middle part be provided with the second pilot hole, second sliding axle is arranged in second pilot hole；The spring is set to second
On sliding axle, and between flap and the second leading truck；The flap is arched, and is provided in the both ends of the surface of the flap
One water ring, opposite first water ring location is provided with the second water ring, first water ring and second on the first valve seat inner face
Water ring forms closed water ring structure when flap is abutted with the first valve seat, and perforation described first is provided on second water ring
The osculum of valve seat.
The utility model by being arranged spring on the second sliding axle, spring be located at the second sliding axle and the second leading truck it
Between, be conducive to after water pump stops supplying water, under the action of the spring, flap quickly abuts the first valve seat；By the two of flap
The first water ring is arranged in end face, and the position of opposite first water ring is arranged the second water ring on the inner face of the first valve seat, the first water ring and
Second water ring forms closed water ring structure when flap is abutted with the first valve seat, and the first valve seat of perforation is provided on the second water ring
Osculum, since the effect of spring and flow makes flap be moved to the water inlet direction of valve body, due to the first water ring and
The setting of two water rings, before flap soon abuts the first valve seat, flap can compress the water in the second water ring, the water in the second water ring
It is discharged by osculum, since the aperture of osculum is smaller, the water in the second water ring can play the movement of flap in the work of buffering
With to make the speed of flap reduce, that finally realizes between flap and the first valve seat steady abuts.First sliding axle, flap
And the second sliding axle integrally connected, advantageously ensure that the stability of the first sliding axle, flap and the second sliding axis connection, tool
There are good physical property, while installation easy to disassemble.
Preferably, primary sealing area and are both provided between the inner face of the both ends of the surface of the flap and the first valve seat
Two sealing surfaces.The setting of primary sealing area and secondary sealing area advantageously ensures that the leakproofness between flap and the first valve seat.
Preferably, the inclination angle of the primary sealing area is 30 ° to 45 °.It is certain to the abutting force of primary sealing area in flap
In the case of, the inclination angle of primary sealing area is 30 ° to 45 °, it is possible to reduce flap to the active force of primary sealing area vertical direction,
It advantageously reduces flap and abuts the water attack sound generated when primary sealing area and vibration.
Preferably, first water ring and the second water ring are separately positioned on the primary sealing area.
Preferably, it is provided with O-ring seal on the secondary sealing area of first valve seat.The setting of O-ring seal is advantageous
Volume leakproofness between guarantee flap and the first valve seat, anti-non-return water are flow backwards.
Preferably, it is provided with limited step on second sliding axle.The limited step being arranged on second sliding axle, a side
Face can ensure that flap is opened to maximum stream flow, on the other hand can be the second sliding axle can be prevented to be detached from from the second guiding.
Preferably, first valve seat is connect with the valve body screw thread.First valve seat is connect with valve body screw thread, it is ensured that
Secured connection between first valve seat and valve body.
Preferably, second leading truck is connect with the valve body screw thread.Second leading truck is connect with valve body screw thread, can be with
Ensure the secured connection between the second leading truck and valve body.
Preferably, the first axle sleeve and the second axle sleeve are respectively arranged in first pilot hole and the second pilot hole.
Axle sleeve is set in first pilot hole and the second pilot hole, advantageously reduces the resistance that the first sliding axle slides in the first pilot hole
Power advantageously reduces the resistance that the second sliding axle slides in the second pilot hole.
Preferably, the aperture of the osculum is 2mm to 5mm, and the pore size of osculum is 2mm to 5mm, is conducive to
When squeezing the second water ring, return water is discharged flap from osculum, the osculum setting of smaller aperture due so that return water is to flap speed
Slow down effect it is more obvious.
Compared with prior art, the utility model has the beneficial effects that：
The utility model is that a kind of liquid-ring type buffers damping check valve, by the way that spring, spring are arranged on the second sliding axle
Between the second sliding axle and the second leading truck, be conducive to after water pump stops supplying water, under the action of the spring, flap is quick
Abut the first valve seat；By the way that the second water ring is arranged on the first valve seat, the first water ring is set on flap, is arranged on the second water ring
The osculum for penetrating through the first valve seat, before flap soon abuts the first valve seat, flap compresses the water in the second water ring, the second water ring
In water be discharged by osculum, since the aperture of osculum is smaller, the water in the second water ring can play the movement of flap slow
The effect of punching, to make the speed of flap reduce, finally realize between flap and the first valve seat it is steady abut, be conducive to eliminate
Echo when flap is abutted with the first valve seat.The utility model, which realizes, to close slowly after liquid-ring type buffering damping check valve elder generation quick closing valve
Effect has not only achieved the effect that eliminate water hammer, but also has achieved the purpose that increase check-valves service life.
