Description
Technical field
The utility model relates to a kind of one-way valve, particularly relates to a kind of two logical one-way valves for automobile.
Background technique
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.In prior art, one-way valve is all the single input adopted, single mode exported.But usually need dual output in actual applications, at this moment just need after output terminal shunting, install two one-way valves simultaneously and just can prevent the reverse fluid flow after shunting.Like this, consumptive material is many, uses also inconvenient.
Model utility content
The technical problems to be solved in the utility model is to provide the two logical one-way valves that a kind of structure is simple, consumptive material is few, easy to use, achieves the single input of fluid, dual output, also prevent the reverse flow of the fluid after shunting simultaneously.
For solving the problems of the technologies described above, the technical solution of the utility model is: provide a kind of two logical one-way valves, comprise valve body, two valve gaps and two valve blocks, fluid chamber is formed in valve body, the upper end of valve body forms the import be communicated with fluid chamber, the both sides of valve body form first interface and the second interface, first interface and the second interface include outer shroud and inner ring, two valve gaps are connected with first interface and the second interface respectively, the connecting end of valve gap is stuck between outer shroud and inner ring, the inwall of inner ring is inwardly outstanding forms limited ring, the joint of inner ring and limited ring forms valve block draw-in groove, inner ring is provided with breach, two valve blocks are by maintenance block, contiguous block and lamellar body composition, lamellar body is round structure and the diameter of lamellar body is greater than the internal diameter of limited ring, lamellar body is stuck in valve block draw-in groove and lamellar body is close to limited ring and is arranged, maintenance block is stuck between inner ring and outer shroud, the lamellar body of inner ring both sides is connected with maintenance block through breach by contiguous block, the inner side of two valve gaps is all inwardly outstanding forms limiting stopper, activity space is formed between limiting stopper to lamellar body, the free end of two valve gaps forms the first outlet and the second outlet respectively.When there being fluid to be entered in fluid chamber by the import on valve body, the equal mineralization pressure of the lamellar body of fluid to two valve blocks, originally the lamellar body be close on limited ring is offset to limiting stopper, and the first outlet and the second outlet are all opened, and fluid is flowed out by the first outlet and the second outlet.Limiting stopper restriction lamellar body skew, make lamellar body be unlikely to skew excessive after be difficult to get back to home position.When fluid is from the first outlet and the second outlet input, although two valve blocks all receive the pressure from fluid, but two valve blocks receive the holding power of limited ring simultaneously, limit two valve blocks to offset respectively to respective limited ring direction, reach the effect of the reverse flow of anti-fluid, also achieve the single input of fluid, dual output simultaneously.In single valve body, achieve the single input of fluid, dual output, also prevent the reverse flow of the fluid after shunting simultaneously, whole two logical one-way valve structures are simple, consumptive material is few, easy to use.
Further, the width of described breach equals the width of contiguous block.Be limited in valve block and rocking when offseting occurs, can original position be returned to when making valve block not be subject to hydrodynamic pressure, limited ring is blocked, prevent having fluid to enter in fluid chamber during reverse fluid flow.
Further, described valve block is made up of rubber.Valve block adopts rubber material to make, and makes when valve block is subject to can offseting from during hydrodynamic pressure in fluid chamber, and fluid is more prone to from the first outlet or the second outlet outflow.
Further, described two logical one-way valves also comprise two seal rings, and the first outlet and the second outlet are provided with o-ring groove, and two seal rings are placed in the o-ring groove of the first outlet and the second outlet respectively.The setting of seal ring, improves the first outlet or second and exports the sealing effect after being connected with extraneous pipeline, prevent fluid from the outflow of joint.
Further, described first outlet and the second outlet are provided with some projections.The projection arranged coordinates with nylon tube, and the first outlet or the second outlet are fitted more with the connection of nylon tube.
The beneficial effects of the utility model: when fluid is from the first outlet and the second outlet input, although two valve blocks all receive the pressure from fluid, but two valve blocks receive the holding power of limited ring simultaneously, limit two valve blocks to offset respectively to respective limited ring direction, reach the effect of the reverse flow of anti-fluid, also achieve the single input of fluid, dual output simultaneously, whole two logical one-way valve structures be simple, consumptive material is few, easy to use.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment: as shown in Figures 1 to 4, a kind of two logical one-way valves comprise valve body 1, two valve gaps 2, two valve blocks 3 and two seal rings 4.
Please refer to shown in Fig. 5 to Fig. 9, form fluid chamber 10 in valve body 1, the upper end of valve body 1 forms the import 11 be communicated with fluid chamber 10, and the both sides of valve body 1 form first interface 12 and the second interface 13.First interface 12 and the second interface 13 include outer shroud 121 and inner ring 122, and the inwall of inner ring 122 is inwardly outstanding forms limited ring 123, and the joint of inner ring and limited ring 123 forms valve block draw-in groove, inner ring is provided with breach 124.In the present embodiment, the structure of import 11 be used for rubber pipe with the use of.
Please refer to Figure 10, two valve blocks 3 form by maintenance block 31, contiguous block 32 and lamellar body 33, lamellar body 33 is round structure and the diameter of lamellar body 33 is greater than the internal diameter of limited ring 123, and maintenance block 31 is connected with lamellar body 33 by contiguous block 32, and maintenance block 31, contiguous block 32 and lamellar body 33 are one-body molded.In the present embodiment, the width of described breach 124 equals the width of contiguous block 32.Described valve block 3 is made up of rubber.
Please refer to shown in Fig. 1, Figure 11 and Figure 12, the inner side of two valve gaps 2 is all inwardly outstanding forms limiting stopper 21, and limiting stopper 21 forms activity space between lamellar body 33, and the free end of two valve gaps 2 forms the first outlet 22 and the second outlet 23 respectively.First outlet 22 and the second outlet 23 are provided with o-ring groove 24.Described first outlet 22 and the second outlet 23 are provided with some protruding 25, make the first outlet 22 or the second outlet 23 for nylon tube with the use of.
