Embodiment
The present invention has designed a kind of Novel check valve, as shown in Figure 1, comprise valve body 110, spool 120 and spring 130, wherein, also comprise spring stop 141 and at least 2 draw-in grooves 142, described valve body 110 is whole unidirectional valve housing, is used for all inner members of encapsulation, valve body 110 inside are provided with liquid entering hole 111, valve chamber 112 and liquid outlet 113, are used for the out-of-date zones of different of difference flow and the flow direction of fluid.
Described spool 120 comprises valve core head 121, spool filler opening 122 and spool sidewall 123, valve core head 121 is used for cooperating with liquid entering hole 111 and spring 130, control the flowing velocity of switch and the fluid of one-way valve, fluid is by spool filler opening 122, flow into spool 120 inside from valve chamber 112, spool sidewall 123 is main bodys of spool 120, and the mobile and control that is used for the guiding fluid stretches along fixed-direction.
Described spool 120 is arranged on described valve body 110 inboards, described spring 130 is arranged on described spool 120 inboards, 130 1 on described spring is connected with described valve core head 121, the other end is connected with spring stop 141, when valve core head 121 was subject to hydrodynamic pressure, pressure conduction shrank spring 130 and shortens to spring 130, spool 120 and spring 130 integral body retreat the one-way valve conducting.
Described draw-in groove 142 is arranged on described liquid outlet 113 internal surfaces, described draw-in groove 142 has the internal diameter of stepped change, the length that described spring stop 141 is regulated described spring 130 by being stuck in described draw-in groove 142 inside is controlled the conducting pressure of one-way valve and the velocity of liquid assets of fluid by the length of Regulation spring 130.
Described a kind of Novel check valve wherein, also is provided with valve seat 151 and seal ring 152 at described liquid entering hole 111, is used for better preventing that fluid from refluxing.
Described a kind of Novel check valve, wherein, corrosion-resistant and heat-resisting processing has all been carried out on the surface of described valve body 110, spool 120, spring 130 and spring stop 141, by processing so that whole one-way valve is more durable, increase working life, reduced maintenance cost.
