Abstract
The utility model provides a valve with a Y-shaped sealing part and belongs to the technical field of valves. The valve comprises a valve body, an upper sleeve, a lower sleeve, a valve core, a valve cover and a sealing part, wherein the upper sleeve and the lower sleeve are sealed through the Y-shaped sealing part; the section of the Y-shaped sealing part is in a Y-shaped structure; the end face of the Y-shaped sealing part is provided with a V-shaped groove; a V-shaped spring is arranged in the V-shaped groove; the Y-shaped sealing part provided with the V-shaped spring is arranged in a sealing groove of the upper sleeve; and a polytetrafluoroethylene (PTFE) flat gasket is arranged between the Y-shaped sealing part and the sealing groove. The V-shaped spring is arranged in the V-shaped groove of the Y-shaped sealing part in the valve, and the sealing wear in the using process can be properly compensated, so that the service life of the sealing part is prolonged; and moreover, due to the Y-shaped sealing structure, the phenomenon that the sealing part is damaged due to the axial shear action of the valve core on the sealing part is avoided in the process of assembling the valve core and the sleeves, and the service life of the sealing part is prolonged.
Description
Technical field
The utility model relates to valve technology field, specifically a kind of valve that has Y shape sealed member.
Background technique
General, the sealed member of the built-in ordinary construction of spool outer wall trench is generally adopted in sealing between conventional valves spool and the sleeve, can't compensate after the sealed member wearing and tearing and cause seal failure, produces the dielectric leakage phenomenon.
Summary of the invention
The technical assignment of the utility model is the deficiency that solves existing technology, and a kind of valve of the Y of having shape sealed member is provided.
The technological scheme of the utility model realizes by following mode; This has the valve of Y shape sealed member; Its structure comprises valve body, upper bush, lower sleeve, spool and valve gap, and this valve also comprises sealed member: seal through Y shape sealed member between upper bush and the lower sleeve.
The section of Y shape sealed member is a Y shape structure, and the end face of Y shape sealed member is provided with vee-cut, is provided with the V-arrangement spring in the vee-cut.
The Y shape sealed member that is provided with the V-arrangement spring places in the seal groove of upper bush, is placed with the PTFE plain cushion between Y shape sealed member and the seal groove.
The section of Y shape sealed member is a Y shape structure; The upper-end surface processes vee-cut; The V-arrangement spring is placed in the vee-cut, the V-arrangement spring is pressed in the vee-cut, then the Y shape sealed member that assembles is placed in the seal groove of upper and lower sleeve with plain cushion; V-arrangement spring Y shape sealed member produces lateral extrusion power, thereby reaches the purpose of sealing.Seal with Y shape sealed member between sleeve, sleeve and the spool up and down.
The valve of band Y shape sealed member; Y shape sealed member is installed in the seal groove of upper bush; There is a PTFE plain cushion upper-end surface, through valve gap, upper bush Y shape sealed member is compressed and makes it to produce extruding force and extrusion-deformation, and the V-arrangement spring produces lateral extrusion power to Y shape sealed member simultaneously.
The beneficial effect that the utility model is compared with prior art produced is:
This has in the vee-cut of the Y shape sealed member in the valve of Y shape sealed member the V-arrangement spring is housed, and behind the sealing wear an amount of compensation can be arranged in the using process, thereby prolong the working life of sealed member.
The Y shape sealing configuration of Y shape sealed member, make spool with the sleeve assembly process in, avoided spool that the axial shear action of sealed member is caused the damage of sealed member, prolong the working life of sealed member.
This have the valve design of Y shape sealed member reasonable, simple in structure, safe and reliable, easy to use, be easy to safeguard, have good value for applications.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model;
Accompanying drawing 2 is local structure for amplifying schematic representation of A part in the accompanying drawing 1.
