Background technique
One-way valve is that fluid can only flow along water intake, and water outlet medium but cannot reflux, and is commonly called as one-way valve.One-way valve is also known as safety check or check valve.For preventing oil stream reverse flow in hydraulic system, or for preventing pressurized air reverse flow in pneumatic system.One-way valve has straight-through type and right-angle type two kinds.Straight check valve is arranged on pipeline with being threaded.Angle check valve is threaded, board-like connection and Flange joint three kinds of forms.Wherein angle check valve use process in, when the water flow in valve body and water flow pressure excessive time can cause one-way valve clamping stagnation, unnecessary damage is caused to one-way valve, so design a kind of Novel check valve just seem particularly important.
Summary of the invention
To the defect that above-mentioned background technology exists, the problem to be solved in the present invention is by arranging overflow ducts and relief valve makes the design have the function of self-protection, prevent one-way valve to be damaged when excessive water flow and water flow pressure, decrease potential safety hazard; A kind of Novel check valve is provided.
For solving above-mentioned technical problem, structure of the present invention comprises valve body and flange, described valve body is by flow orifice plate, internals, Sealing and outer member connect to form successively, the outside of described flow orifice plate and outer member is connected to a flange, threaded connector is provided with between two described flanges, two described flanges are threaded connection part to flow orifice plate, internals, Sealing and outer member clamp, Inner guide passage is offered in described internals, described Inner guide passage is connected with the metering orifice in flow orifice plate, frustoconic shape through hole is offered in described outer member, one end of described Sealing stretches in the frustoconic shape through hole of outer member, outer guide channel is formed between the inwall of the frustoconic shape through hole of described outer member and the sidewall of Sealing, in described internals Inner guide passage sidewall on offer pod apertures, described pod apertures is connected with outer guide channel through Sealing, also overflow ducts is offered in described internals, described Inner guide passage is connected with outer guide channel by overflow ducts, relief valve is provided with in described overflow ducts.
Further: described relief valve comprises valve cylinder, spool, spring and valve gap, described valve cylinder is arranged in overflow ducts, described valve gap is fixedly connected on the outlet end of valve cylinder, described spool is movably connected in valve cylinder, described spool is connected with valve gap by spring, the sidewall of described valve cylinder offers the first overflow hole, described valve gap offers the second overflow hole relative to the position of the first overflow hole, the first described overflow hole is connected with outer guide channel by the second overflow hole.
Further again: between described flow orifice plate and internals, to be provided with the first sealing gasket, described flow orifice plate and be provided with the second sealing gasket between outer member and flange.
Adopt after said structure, the present invention, by arranging overflow ducts and relief valve makes the design have the function of self-protection, prevents one-way valve to be damaged when excessive water flow and water flow pressure, decreases potential safety hazard; And the design has the advantage that structure is simple, be easy to manufacture and practicality and high efficiency.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of relief valve.
Embodiment
A kind of Novel check valve as shown in Figure 1, comprise valve body and flange 1, described valve body is by flow orifice plate 3, internals 5, Sealing 6 and outer member 7 connect to form successively, the outside of described flow orifice plate 3 and outer member 7 is connected to a flange 1, threaded connector is provided with between two described flanges 1, two described flanges 1 are threaded connection part to flow orifice plate 3, internals 5, Sealing 6 and outer member 7 clamp, Inner guide passage 8 is offered in described internals 5, described Inner guide passage 8 is connected with the metering orifice in flow orifice plate 3, frustoconic shape through hole is offered in described outer member 7, one end of described Sealing 6 stretches in the frustoconic shape through hole of outer member 7, outer guide channel 9 is formed between the inwall of the frustoconic shape through hole of described outer member 7 and the sidewall of Sealing 6, in described internals 5 Inner guide passage 8 sidewall on offer pod apertures 10, described pod apertures 10 is connected with outer guide channel 9 through Sealing 6, overflow ducts 11 is also offered in described internals 5, described Inner guide passage 8 is connected with outer guide channel 9 by overflow ducts 11, relief valve 12 is provided with in described overflow ducts 11.Be provided with the first sealing gasket 4 between described flow orifice plate 3 and internals 5, described flow orifice plate 3 and be provided with the second sealing gasket 2 between outer member 7 and flange 1, described Sealing 6 offers guide channel relative to the position of pod apertures 10.By two side flanges 1, one-way valve is connected as in pipeline system during work, current are flowed in Inner guide passage 8 by metering orifice, then flows in outer guide channel 9 by pod apertures 10, finally flow out from outer guide channel 9; When the water flow flowing through one-way valve is excessive or hydraulic pressure is excessive, relief valve 12 can start voluntarily, and the current in Inner guide passage 8 can also be flowed in outer guide channel 9 by overflow ducts 11.The present invention makes it have the function of self-protection by arranging overflow ducts and relief valve, prevent one-way valve to be damaged when excessive water flow and water flow pressure, decrease potential safety hazard.
