Description
technical field:
The utility model relates to a kind of one-way valve.
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.During traditional non-return valve operational, spool and one-way valve inwall can produce shock, under clashing into for a long time, easily cause damage to spool, affect the working life of one-way valve.And the spring of traditional one-way valve inside often contacts with fluid-phase, after a protracted use, the easy rust corrosion of spring, affects the working life of spring.
summary of the invention:
The purpose of this utility model is to solve the problems of the prior art, provides that a kind of structure is simple, spring does not contact with fluid-phase, and the operationally one-way valve that do not collide of spool and valve body.
In order to achieve the above object, the technical solution of the utility model is:
One-way valve, comprises and screws togather connected upper valve base and lower valve base, forms cavity between described upper valve base and lower valve base, is provided with spool in described cavity, and described spool comprises plug and pedestal, and described plug and pedestal are integrated manufacture and form; Described pedestal offers the first row water hole and second row water hole that are interconnected, described pedestal is also provided with the first seal ring, described first seal ring is connected with the inwall of upper valve base; Described pedestal is connected with connecting tube, and described connecting tube screws togather with upper valve base and is connected, and described connecting tube is provided with set screw nut; The inwall of described upper valve base is provided with snap ring, and described plug engages with snap ring and is connected; Described lower valve base offers through hole, in described through hole, offers screw thread.
Described pedestal comprises top base and is socketed in the bottom base outside described top base, offers circular groove in described top base, and described circular groove inside is provided with spring, and the two ends in described spring are fixedly linked with top base, bottom base respectively.
Described bottom base is provided with the second seal ring and the 3rd seal ring, described second seal ring is connected with the outer side wall of top base, and described 3rd seal ring is connected with the madial wall of top base.
Described plug offers projection, described snap ring offers the draw-in groove matched with described convex shape.
Described lower valve base offers groove, in described groove, buffer ring is installed.
The beneficial effects of the utility model are: one-way valve of the present utility model, and upper valve base screws togather with lower valve base and is connected, and is convenient to the laid-up of valve body; Spring fitting in circular groove, and is sealed by the second seal ring and the 3rd seal ring, avoids spring and fluid contact; Plug, snap ring are connected with draw-in groove engaging by protruding, avoid the collision of spool to valve body, add the working life of one-way valve.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
embodiment:
Embodiment 1
One-way valve as shown in Figure 1, comprise and screw togather connected upper valve base 1 and lower valve base 2, between described upper valve base 1 and lower valve base, form cavity 3, in described cavity 3, spool 5 is installed, described spool 5 comprises plug 6 and pedestal 7, and described plug 6 is integrated manufacture with pedestal 7 and forms.Described pedestal 7 offers the first row water hole 78 be interconnected and second row water hole 79, described pedestal 7 is also provided with the first seal ring 75, described first seal ring 75 is connected with the inwall of upper valve base 1.
Described pedestal 7 comprises top base 71 and is socketed in the bottom base 72 outside described top base 71, circular groove 73 is offered in described top base 71, described circular groove 73 inside is provided with spring 74, and the two ends in described spring 74 are fixedly linked with top base 71, bottom base 72 respectively.Described bottom base 72 is provided with the second seal ring 76 and the 3rd seal ring 77, described second seal ring 76 is connected with the outer side wall of top base 72, and described 3rd seal ring 77 is connected with the madial wall of top base 72.Second seal ring 76 and the 3rd seal ring 77 can slide along the inwall of top base 72, and stop fluid to enter in figure circular groove 73.
Described pedestal 7 is connected with connecting tube 8, and described connecting tube 8 screws togather with upper valve base 1 and is connected, and described connecting tube 8 is provided with set screw nut 9.Connecting tube 8 can promote bottom base 72, changes the elasticity coefficient of spring 74, thus regulates fluid by impact force requirement required during one-way valve.The inwall of described upper valve base 1 is provided with snap ring 4, and described plug 6 engages with snap ring 4 and is connected.Described plug 6 offers protruding 61, described snap ring 4 offers the draw-in groove 41 with described protruding 61 mating shapes.Described lower valve base 2 offers through hole 21, in described through hole 21, offers screw thread.Described lower valve base 2 offers groove 22, in described groove 22, buffer ring 23 is installed.Buffer ring 23 can increase the sealing of one-way valve, also can play buffer function when upper valve base 1 and lower valve base 2 screw togather.
