Description
Technical field
The present invention relates to valve technology field, is specially a kind of double check valve.
Background technology
Check-valves refers to flow in itself by medium and automatic open and close flap, for preventing the valve of medium refluence, non-return
Valve belongs to a kind of automatic valve, its main function is to prevent medium from flowing backwards, prevent pump and drive motor reversion, and container to be situated between
Matter is released, and when water pump is cut off the water, sealing flows back not in time existing check-valves, often has current and is back in water pump, this
Sample does not just reach the effect of sealing reflux, influences task under water pump.
Existing water check valve is all that one-way water stop flows back, and use scope is limited, and winter exposed pipeline, works as water pump
, can be freezing by pipeline if do not discharged the liquid in pipeline in time during shutdown, so need current being isolated in outside valve body,
Prevent the current in valve body from penetrating into water pump.
The content of the invention
It is an object of the invention to provide a kind of double check valve, to solve the problems mentioned in the above background technology.
To achieve the above object, the present invention provides following technical solution：A kind of double check valve, including valve body, the first valve
Lid and the second valve deck, described valve body one end are connected with the first valve deck by bolt thread, and the valve body other end passes through bolt spiral shell
Line is connected with the second valve deck, and the first valve deck bottom is fixedly connected with first flange disk, is provided with the ring flange center
Water inlet, the second valve deck top are fixedly connected with second flange disk, water outlet are provided with the second flange disk center,
The first valve deck inner wall is symmetrically fixedly connected with into water spring, the described one end of water inlet spring away from the first valve deck and is fixedly connected
Have into water valve plate, the second valve deck inner wall is symmetrically rotatably connected to water outlet valve plate by hinge, at the water outlet valve plate center
Water outlet spring is fixedly connected with, the described one end of water outlet spring away from water outlet valve plate is fixedly connected with the second valve deck.
Preferably, the crevice place of first valve deck and first flange disk is fixedly connected with the first gasket.
Preferably, the crevice place of second valve deck and second flange disk is fixedly connected with the second gasket.
Preferably, the first valve deck both sides are symmetrically fixedly connected with convex block, and the valve body both sides are symmetrically arranged with cooperation
The groove of convex block.
Preferably, it is fixedly connected with fixed frame inside first valve deck.
Compared with prior art, the beneficial effects of the invention are as follows：
The present invention can quickly block current to flow back in water pump by adding water inlet spring, when in use, open water pump, water
Pump makes current be flowed in pipeline, and hydraulic pressure enters water inlet, opens water inlet valve plate by hydraulic pressure, water inlet spring is upheld, such water
Stream is put into valve body, and after water pump closing, hydraulic pressure is smaller, spring contraction of intaking, so as to drive inlet valve sheet reset, thus
It can be very good to block current reflux.
The present invention can be blocked in current return valve body by adding water outlet valve plate, in pump working, the water in valve body
Miscarriage unboiled water pressure, rotates, current pass through water check valve, after water pump is stopped, valve body so as to press water outlet valve plate around hinge
Interior current stop, and water outlet recoil of spring simultaneously drives water outlet valve plate to be rotated around hinge, and then outlet valve sheet reset, blocks current to return
Flow into valve body, which prevent there is water to penetrate into water pump in valve body, avoiding has water in winter valve body, so that freezing pipeline.

Embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment, belongs to the scope of protection of the invention.
- 3 are please referred to Fig.1, the present invention provides a kind of technical solution：A kind of double check valve, including valve body 1, the first valve deck 2
With the second valve deck 14, described 1 one end of valve body is threaded with the first valve deck 2 by bolt 11, and 1 other end of valve body passes through spiral shell
Bolt 11 is threaded with the second valve deck 14, and 2 bottom of the first valve deck is fixedly connected with first flange disk 5, in the ring flange 5
Water inlet 3 is provided with the heart, the top of the second valve deck 14 is fixedly connected with second flange disk 6,6 center of second flange disk
Place is provided with water outlet 4, and 2 inner wall of the first valve deck is symmetrically fixedly connected with remote into water spring 15, the water inlet spring 15
One end of first valve deck 2 is fixedly connected with into water valve plate 13,14 inner wall of the second valve deck and is symmetrically rotatablely connected by hinge 18
There is water outlet valve plate 16, water outlet spring 17 is fixedly connected with 16 center of water outlet valve plate, the water outlet spring 17 is away from water outlet
One end of valve plate 16 is fixedly connected with the second valve deck 14.
The crevice place of first valve deck 2 and first flange disk 5 is fixedly connected with the first gasket 7, by adding the first pad
Piece 7 adds the leakproofness between the first valve deck 2 and first flange disk 5, the crack of second valve deck 14 and second flange disk 6
Place is fixedly connected with the second gasket 8, is added by the second gasket 8 of addition close between the second valve deck 14 and second flange disk 6
Feng Xing, so as to improve the leakproofness of check-valves, 2 both sides of the first valve deck are symmetrically fixedly connected with convex block 9, the valve body 1
Both sides are symmetrically arranged with the groove 10 for coordinating convex block 9, are used cooperatively by convex block 9 and groove 10, facilitate the dismounting of check-valves,
Fixed frame 12 is fixedly connected with inside first valve deck 2, will not be by water into water spring 15 by adding that fixed frame 12 protects
Stream washes out, and improves the service life into water spring 15.
Operation principle：When in use, water pump is opened, water pump makes current be flowed in pipeline, and hydraulic pressure enters water inlet 3, leads to
Cross hydraulic pressure open water inlet valve plate 13, water inlet spring 15 uphold, such current are put into valve body 1, water pump closing after, hydraulic pressure compared with
Small, water inlet spring 15 is shunk, so as to drive water inlet valve plate 13 to reset, thus can be very good to block current reflux, in water pump
During work, current in valve body 1 produce hydraulic pressure, are rotated so as to press water outlet valve plate 16 around hinge 18, current by water check valve,
After water pump is stopped, current stop in valve body 1, and water outlet spring 17 springs back and drives water outlet valve plate 16 around 18 turns of hinge
Dynamic, then water outlet valve plate 16 resets, and blocks in current reflux inlet valve body 1, which prevent there is water to penetrate into water pump in valve body 1,
Avoiding in winter valve body 1 has water, so that freezing pipeline.
