Abstract
The utility model relates to a valve, especially relate to a check valve can deflect. The utility model discloses the metal check valve can not compensate the displacement in aiming at solving prior art, and has the fragile rigid poor low problem of life -span of the check valve of valve. The utility model discloses a valve body both ends are equipped with the flange, including rubber valve body and valve cartridge, the valve body is made by rubber, is equipped with wave form form bulge loop in the middle part of it, valve cartridge forms axle sleeve complex duckbill valve with the valve body in being in this valve body. The utility model has the advantages of the valve body is rubber, and the shock attenuation is stepped down, and the compensation displacement can flexiblely be warp, use flange joint, installation, easy maintenance, whole the opening of rubber check valve is full -automatic with closed working process, no matter be valve body or valve cartridge, be 3 layers, embedded enhancement layer, intensity is high, wherein the party damages, can change the back rapidly, does not influence holistic reusing, has lengthened life.
Description
Technical field
The utility model relates to a kind of valve, particularly relates to a kind of flexible safety check.
Background technique
Safety check is also known as check valve, one-way valve, one-way valve or check valve, and its effect is the function ensureing medium directional flow in pipeline and unlikely refluence.Open-shut device is opened voluntarily by media flow and strength or closes, and the valve flow backwards to prevent medium is on safety check.Safety check belongs to self-acting valve class, is mainly used on the pipeline of medium one-way flow, only allows medium to flow to a direction, to try to avert accidents.Especially at the outlet pipe section of water pump, existing check valve structure is complicated, and volume is large, and price is high.
In the patent documentation announced of China, publication No. is the model utility of exhibition safety check in CN2578634Y, flexible valve by name, devises a kind of by carrying out the technological scheme of restriction conduit one-way flow by the rubber valve that is out of shape to side of one direction.
But it is as follows that above-mentioned technology exists shortcoming: 1. valve capsule is in safety check inside, with safety check one, after Long-Time Service, mould rigid changing, once inner valve capsule generation embrittlement due to its material surface, overall safety check is just equivalent to scrap, and working life is low; 2. the manufacturing process of valve capsule is complicated, and cost is high.
Summary of the invention
The purpose of this utility model is exactly can not compensate for displacement in order to solve in prior art metal safety check, and with the safety check crisp rigid poor life-span of valve low problem.
Concrete scheme of the present utility model is:
Design a kind of flexible safety check, its valve body two ends are provided with flange, and comprise rubber valve body and valve cylinder, valve body is made up of rubber, and be provided with waveform shape bulge loop in the middle part of it, valve cylinder is in this valve body, are to form the duckbill Valve that axle sleeve coordinates with valve body.
Axle sleeve coordinates for duckbill Valve is bolted in valve body.
It is be interference fit between the external diameter of duckbill Valve and the internal diameter of valve body that axle sleeve coordinates.
Valve body is from comprising outer layer rubber, framework layer, internal layer rubber outside to inside, and framework layer is made up of kiss-coating tyre cord.
Valve cylinder is from comprising outer layer rubber, framework layer, internal layer rubber outside to inside, and framework layer is made up of kiss-coating tyre cord.
Valve body is provided with steel traveler in the cambered surface contacted with duckbill Valve.
The beneficial effects of the utility model are:
1. valve body is rubber, damping step-down, compensate for displacement, can flexible deformation;
2. use Flange joint, install, easy to maintenance;
3. the whole unlatching of rubber check valve is full-automatic with closed working procedure, interferes, save artificial, environment friendly and pollution-free without the need to artificial, electricity, gas equal energy source;
4. no matter be valve body or valve cylinder, be 3 layers, embedded reinforced layer, intensity is high;
5. between valve body with valve cylinder for shaft sleeve coordinates, if wherein a side damages, after can changing rapidly, do not affect overall reusing, extend working life.

Each component names in figure: 1. flange; 2. valve body; 3. valve cylinder; 4. steel traveler.
Embodiment
Embodiment 1: see Fig. 1 ~ Fig. 5, designs a kind of flexible safety check, and its valve body two ends are provided with flange, comprise rubber valve body 2 and valve cylinder 3, valve body 2 is made up of rubber, is provided with waveform shape bulge loop in the middle part of it, valve cylinder 3 is in this valve body 2, is to form the duckbill Valve that axle sleeve coordinates with valve body 2.Valve body is straight-through waveform, can damping noise reduction, and the thrust that extraction duct is expanded with heat and contract with cold, reduces structure-borne noise.As the intermediate muster in Fig. 1 structure very as described in waveform shape bulge loop.
Axle sleeve coordinates for duckbill Valve is bolted in valve body 2.During work, open at one end, one end closes, and when fluid pump is opened, fluid is flowed into by open-mouth end, and under the effect of hydraulic thrust, closed end opens automatically, and fluid passes through.When fluid pump quits work, closed end closes automatically, prevents liquid backflow, damages the equipment such as pump valve.
Valve body 2 is from comprising outer layer rubber, framework layer, internal layer rubber outside to inside, and framework layer is made up of kiss-coating tyre cord.
Valve cylinder 3 is from comprising outer layer rubber, framework layer, internal layer rubber outside to inside, and framework layer is made up of kiss-coating tyre cord.
Valve body 2 is provided with steel traveler 4 in the cambered surface contacted with duckbill Valve.Play the effect of reinforcement.
Flange 1 has two panels, is positioned at safety check two ends, and flange 1 has bolt hole, is connected on pipeline or equipment by bolt hole.
Embodiment 2: the present embodiment principle is with embodiment 1, and see Fig. 6, concrete difference is, it is are interference fit between the external diameter of duckbill Valve and the internal diameter of valve body 2 that axle sleeve coordinates.
Finally it should be noted that, above person is only the utility model part embodiment, and is not used to limit the present invention, and according to structure of the present utility model and feature, the modifications person of forming a little, also should be included within the utility model scope.
