Abstract
The utility model relates to a throttle valve which comprises a valve body, a reset spring and a valve element. An annular groove is formed in the valve body, a corresponding annular groove is further formed in the outer end portion of the valve element, sealing rings are arranged inside the annular grooves, a filter screen is arranged at a liquid inlet of the valve body, and the sealing rings are O-shaped sealing rings. The throttle valve is simple and reasonable in structure, convenient to manufacture, high in sealing performance and capable of effectively filtering colloid, asphalt, carbon residues and other dirt in oil liquid.
Description
Technical field
The utility model relates to the valve parts field, relates in particular to a kind of throttle valve.
Background technique
Throttle valve is by changing throttling cross section or chock length with the valve of control fluid flow, it is streamlined that the open-shut device of throttle valve mostly is greatly circular cone, change channel cross-sectional area by its and reach adjust flux and pressure, throttle valve can be divided into two kinds of straight-through type and angie types by channel mode; Shape by open-shut device is divided, and three kinds of aciculiform, ditch shape and window shapes are arranged.
Throttle valve of the prior art, sealing is relatively poor, and the dirt such as the mechanical admixture in the fluid or the colloid of separating out because of oxidation, pitch, carbon slag easily is deposited in the throttle chink place, affects the using effect of throttle valve.
The model utility content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, provides that a kind of sealability is high, the throttle valve of good filtration effect.
The utility model is to be achieved through the following technical solutions: a kind of throttle valve, comprise valve body, Returnning spring and spool, described valve inner be provided with annular groove, described spool outer end also is provided with corresponding annular groove, in the described annular groove seal ring is set, the ingress of described valve body liquid is provided with filter screen.
Further, described seal ring is " O " shape seal ring.
Compared with prior art, the beneficial effects of the utility model are: the utility model is simple and reasonable, the convenient manufacturing, and sealability is high, can cross the dirts such as colloid in effective filtration fluid, pitch, carbon slag.
Description of drawings
Fig. 1 is the structural representation of a kind of throttle valve of the utility model.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
See also Fig. 1, Fig. 1 is the structural representation of a kind of throttle valve of the utility model.
Described a kind of throttle valve, comprise valve body 1, Returnning spring 2 and spool 3, described valve body 1 inside be provided with annular groove, described spool 3 outer ends also are provided with corresponding annular groove, seal ring 4 is set in the described annular groove, described seal ring 4 is " O " shape seal ring, and the ingress of described valve body 1 liquid is provided with filter screen 5.
By in the groove of spool 3 and valve body 1, seal ring 4 being set, improved the sealing effect of throttle valve, be provided with filter screen 5 in the ingress of valve body 1 liquid simultaneously, can effectively filter the dirts such as colloid in the fluid, pitch, carbon slag.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
