Abstract
The utility model discloses a one-way throttle valve, which belongs to a fluid-control device, solves the problem that a blocking phenomenon can often occur due to pollution generated by a driving fluid and an element of the one-way throttle valve in the prior art, and comprises a joint body A and a joint body B, wherein the joint body A and the joint body B are mutually and fixedly connected, and a sealing ring is arranged between the joint body A and the joint body B; the inner parts of the joint body A and the joint body B are provided with a valve core, the inner part of the valve core is provided with a spring, and one end of the spring is fixed on the joint body A; a through hole is arranged on the valve core; and a throttling groove is arranged on the conical surface of the valve core. The one-way throttle valve is mainly used for fluid control.
Description
Technical field
The utility model belongs to a kind of fluid control device, specifically, relates in particular to a kind of one-way throttle valve.
Background technique
Traditional one-way throttle valve generally is the circular thin-walled throttle orifice of processing on spool.When power transmitting fluids when spool one end flows to spring one end, can open spool, can throttling; When power transmitting fluids flowed to spool one end by spring one end, spool was closed, and fluid can only pass through from the thin-walled throttle orifice on the spool, realizes the effect of throttling with this.But the power transmitting fluids and the element of a lot of systems can produce pollution, when contamination particle size during greater than the size of thin-walled throttle orifice, will produce obstruction, thereby cause whole system to break down cisco unity malfunction easily.At present, also there is not a kind of one-way throttle valve that can effectively avoid blocking phenomenon.
Summary of the invention
Because power transmitting fluids and element produce to be polluted, tend to occur the defective of blocking phenomenon in order to solve one-way throttle valve in the prior art, the utility model provides a kind of one-way throttle valve.
The utility model is achieved through the following technical solutions:
A kind of one-way throttle valve comprises fittings body first and fittings body second, is mutually permanently connected between fittings body first and the fittings body second; Fittings body first and fittings body second inside are provided with spool, and valve core inside is provided with spring, on the end permanent joint body first of spring; Spool is provided with through hole; The conical surface of spool is provided with throttling groove.
Preferably be provided with seal ring between fittings body first and the fittings body second.
Compared with prior art, the beneficial effects of the utility model are: be processed with throttling groove on the spool conical surface, when power transmitting fluids normally circulated, the power of surging of fluid can effectively be cleaned spool, thereby had effectively avoided the generation of blocking phenomenon.

Fig. 2 is throttle figure of the present utility model;
Fig. 3 is the partial enlarged drawing of the A-A of Fig. 2 to sectional view;
Fig. 4 is normal circulation phase diagram of the present utility model;
Fig. 5 is the B place partial enlarged drawing of Fig. 2.
Fittings body first in the drawings, 1; 2, spring; 3, spool; 4, seal ring; 5, through hole; 6, throttling groove; 7, fittings body second.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
A kind of one-way throttle valve comprises fittings body first 1 and fittings body second 7, is mutually permanently connected between fittings body first 1 and the fittings body second 7 and is provided with seal ring 4; Fittings body first 1 is provided with spool 3 with fittings body second 7 inside, and spool 3 inside are provided with spring 2, on the end permanent joint body first 1 of spring 2; Spool 3 is provided with through hole 5; The conical surface of spool 3 is provided with throttling groove 6.
When power transmitting fluids when fittings body first 1 flows to fittings body second 7, spool 3 under the effect of fluid power and spring 2 and fittings body second 7 closely cooperate, the throttling groove 6 on the spool 3 and fittings body second 7 cooperates and forms throttle orifices, power transmitting fluids can only pass through from throttling groove 6, produces restriction effect with this; When power transmitting fluids when fittings body second 7 flows to fittings body first 1, spool 3 promotes spool 3 pressure springs 2 under the effect of fluid power, spool 3 and fittings body second 7 are separately.Power transmitting fluids can pass through around spool 3 and fittings body second 7, and is big by the space, and this moment can be so that fluid normally circulates; When power transmitting fluids can be around spool 3 and the fittings body second 7 by the time, the throttling groove 6 on spool 3 conical surfaces is open, the power of surging can effectively be cleaned the throttling groove 6 on spool 3 conical surfaces, reaches with this to prevent the effect stopped up.
