Abstract
A valve with a two-way sealing part comprises a valve body, an upper sleeve, a lower sleeve, a valve cover, and a two-way sealing part, wherein the upper and the lower sleeves are sealed by the two-way sealing part. Both the upper end surface and the lower end surface of the two-way sealing part are provided with ring-shaped grooves, and coil springs are arranged in the ring-shaped grooves respectively, when in use, an appropriate amount of compensation can be made after the sealing is abraded, so as to prolong the service life of the sealing part. By adopting the two-way sealing structure, the sealing part has a two-way sealing, which prevents the medium from entering the seal pair, so as to produce an excellent sealing effect and prolong the service life of the sealing part.
Description
Technical field
The utility model relates to a kind of valve, particularly relates to a kind of valve that has the two way sealed parts.
Background technique
The conventional sleeve valve up and down generally adopts Y type Sealing between the sleeve, and impurity easily enters sealing pair from the non-tight direction of Sealing and causes seal failure in the medium, produces the medium leakage phenomenon.
Summary of the invention
The purpose of this utility model is to provide a kind of valve that has the two way sealed parts.On the upper-end surface of two way sealed parts, lower end surface, process annular groove respectively, place two wind springs in the annular groove respectively, respectively two wind springs are pressed in the annular groove with two plain cushions, then the two way sealed parts that assemble are placed the seal groove of sleeve up and down, under the effect of upper bush and valve gap, make wind spring compressive strain that the two way sealed parts are produced extruding force, thereby reach sealing purpose.Seal with the two way sealed parts between upper bush and the lower sleeve.
The purpose of this utility model is achieved through the following technical solutions:
The valve of band two way sealed parts is installed in the two way sealed parts in the seal groove of upper bush, and respectively there is a teflon plain cushion upper and lower end face, by valve gap, upper bush the two way sealed parts is compressed.
Advantage of the present utility model and effect are:
1. be equipped with wind spring in the annular groove of two way sealed parts, behind the sealing wear an amount of compensation can be arranged in the using process, thereby prolong the working life of sealed member.
2. the two way sealed structure makes the Sealing two way sealed, and block media enters in the sealing pair, produces good sealing effect, prolongs the working life of sealed member.
Description of drawings
Fig. 1 is the valve mechanism schematic representation in the utility model.
Fig. 2 is the enlarged view of A part among Fig. 1.
Embodiment
Below with reference to Fig. 1, Fig. 2 the utility model is elaborated.
On the upper-end surface of two way sealed parts 6, lower end surface, process annular groove 9, wind spring is placed in the annular groove 9, the two way sealed component-assembled is good.As shown in the figure, graphite wound gasket 2 is packed in the valve body 1, lower sleeve 3 is pressed on the graphite wound gasket 2, mangetic core assembly 4 is packed in the valve seat in the lower sleeve 3, a teflon plain cushion 5 is placed on the lower sleeve 3, in the seal groove of the upper bush 7 of again the two way sealed parts 6 that assemble and teflon plain cushion 5 being packed into, upper bush is put into valve body 1, compress upper bush 7 by valve gap 8, guarantee that two way sealed parts 6 are stressed, thereby realize sealing.The internal diameter of upper bush and two way sealed parts 6 are drive fit.
Claims (3)
1. a valve that has the two way sealed parts comprises valve body, upper bush, lower sleeve and valve gap, it is characterized in that: described valve also comprises the two way sealed parts, seals with the two way sealed parts between upper bush and the lower sleeve.
2. the valve that has the two way sealed parts as claimed in claim 1 is characterized in that: have annular groove on the upper-end surface of two way sealed parts, the lower end surface, be placed with wind spring in the annular groove respectively.
3. the valve that has the two way sealed parts as claimed in claim 2 is characterized in that: the two way sealed parts that have wind spring place in the seal groove of upper bush, are placed with the teflon plain cushion between two way sealed parts and seal groove.
