Description

A kind of valve hard sealing structure of the spare encapsulation scheme of band
Technical field
The invention patent relates to a kind of sealing structures, and in particular to a kind of valve of the spare encapsulation scheme of band seals knot firmly Structure.
Background technique
In the hard sealed valve of reaction-type, relied primarily between spool and valve body sealing surface pressure medium and spring force into Row sealing, when pressure oscillation, sealing performance is unstable, and there is a degree of internal leakages.
Meanwhile by the valve of independent a form of hard sealing structure, after acting for a long time, due to the change of valve parts The presence of the factors such as shape and abrasion, frequently results in the failure of valve sealing structure.
Therefore, industry needs the valve mechanism of the superior hard sealing structure of performance.
Summary of the invention
In order to improve the sealing reliability of the hard sealed valve of reaction-type, the invention proposes dual hard sealed sealing knots Structure is reached by the seal form that plate seal and bulb conical surface seal combine and improves reaction-type hard sealing structure reliability Purpose.
In order to realize above-mentioned technical proposal, the valve hard sealing structure of the spare encapsulation scheme of a kind of band of the invention, by valve Core and valve body are constituted；The valve core sealed cover includes two parts, i.e. planar annular sealing surface and ball face sealing face；Valve body sealing surface Including two parts, i.e. planar annular sealing surface and conical seal (contact) face；The planar annular sealing surface of the spool and the valve body ring Shape flat seal face pressure tightly forms plate seal；The ball face sealing face of the spool and the conical seal (contact) face of valve body compress to form ball Head conical surface seal.
Preferably, described two sealing means are hard sealing, are not related to nonmetallic materials.
A kind of valve hard sealing structure of the spare encapsulation scheme of band of the invention, passes through plate seal and bulb conical surface seal The seal form combined achievees the purpose that improve reaction-type hard sealing structure reliability.When plate seal is due to prolonged After work or movement deform or wear, remain to substantially increase valve seal reliability by bulb conical surface seal.
Detailed description of the invention
Fig. 1 is a kind of schematic diagram of the valve hard sealing structure of the spare encapsulation scheme of band of the embodiment of the present invention；
Fig. 2 is seal spool position view of the embodiment of the present invention；
Fig. 3 is valve seal position view of the embodiment of the present invention.
Specific embodiment
A kind of valve hard sealing structure of the spare encapsulation scheme of band of the embodiment of the present invention it is as shown in Figs. 1-3.
A kind of valve hard sealing structure of the spare encapsulation scheme of band of the embodiment of the present invention specifically includes that spool 1, valve body 2 Composition.1 sealing surface of spool includes two parts, i.e. planar annular sealing surface and ball face sealing face；2 sealing surface of valve body includes two Part, i.e. planar annular sealing surface and conical seal (contact) face；
Sealing means are as follows: during valve working, the planar annular sealing of the planar annular sealing surface and valve body 2 of spool 1 Face pressure tightly forms plate seal；The ball face sealing face of spool 1 and the conical seal (contact) face of valve body 2 compress to form bulb conical surface seal. By the synergy of two kinds of seal forms, guarantee the leakproofness of valve.When plate seal is due to working for a long time or acting After deforming or wearing, remain to substantially increase valve seal reliability by bulb conical surface seal.
