Abstract
The utility model relates to a sealing structure of an adjusting valve using C-shaped metal sealing rings. The sealing structure comprises a sleeve, a valve core seat, a valve core and a valve seat from top to bottom and is characterized in that the first C-shaped metal sealing ring is arranged at a connecting place between the valve core and the valve core seat to realize the sealing connection between the valve core and the valve core seat; and the second C-shaped metal sealing ring is arranged at a connecting place between the inner wall of the lower part of the sleeve and the outer wall of the lower part of the valve core seat, and the third C-shaped metal sealing ring is arranged at a connecting place between the inner wall of the upper part of the sleeve and the top of the valve core seat so as to realize the sealing connection between the sleeve and the valve core seat. In the sealing structure, the multiple C-shaped metal sealing rings are used as sealing parts; as the C-shaped metal sealing rings have the characteristics of high temperature resistance, high pressure resistance, good sealing performance and the like, the sealing structure provided by the utility model resists higher temperature in comparison with the sealing structure using elastic energy storage rings and can meet the requirement that the adjusting valve conveys high temperature liquid.
Description
Technical field
The utility model relates to the modulating valve field, is specifically related to a kind of sealing configuration that is used in the modulating valve.
Background technique
In traditional modulating valve; Sleeve and valve core case, sleeve and spool all adopt the elasticity accumulation of energy circle of Teflon (PTFE) material to seal, but when being to use Teflon (PTFE) elasticity accumulation of energy circle to seal, because the Teflon material can not withstand high temperatures; Therefore the temperature of conveyance fluid can not be higher than below 250 ℃ in the modulating valve; Otherwise deterioration can take place in the accumulation of energy circle, influences sealing effect, even possibly leak.
Summary of the invention
The technical problem that the utility model will solve provide a kind of be used in the modulating valve, simple and reasonable, be easy to install, favorable sealing property and can satisfy modulating valve and carry the high-temp liquid needs to utilize the modulating valve sealing configuration of C type metal o-ring.
The technological scheme that the utility model addresses the above problem is:
A kind of modulating valve sealing configuration that utilizes C type metal o-ring; Comprise sleeve from top to bottom, valve core case, spool and valve seat; It is characterized in that: a C type metal o-ring is established in the jointing place of said spool and said valve core case, realizes being tightly connected of said spool and said valve core case; The 2nd C type metal o-ring is established in the jointing place of the bottom outer wall of the inwall of the bottom of said sleeve and said valve core case; The 3rd C type metal o-ring is established in the jointing place at the inwall on the top of said sleeve and the top of said valve core case, to realize being tightly connected of said sleeve and said valve core case.
The utility model utilizes a plurality of C type metal o-rings as sealed member; Because C type metal o-ring has characteristics such as high temperature resistant, high pressure, good airproof performance; Therefore to use elasticity accumulation of energy circle to compare more high temperature resistant for the sealing configuration of the utility model, can satisfy modulating valve and carry the high-temp liquid needs.

Specific embodiments
Below in conjunction with accompanying drawing the utility model is done further explain.
As shown in Figure 2, a kind of modulating valve sealing configuration that utilizes C type metal o-ring of the utility model comprises sleeve 9 from top to bottom, valve core case 8, spool 2 and valve seat 1.A C type metal o-ring 3 is established in the jointing place of spool 2 and valve core case 8, realizes being tightly connected of spool and valve core case; The 2nd C type metal o-ring 5 is established in the jointing place of the bottom outer wall of the inwall of the bottom of sleeve and valve core case, and the 3rd C type metal o-ring 10 is established in the jointing place at the inwall on the top of sleeve and the top of valve core case, to realize being tightly connected of sleeve and valve core case
In this example as shown in Figure 1, spool is positioned at the valve seat top, and valve core case is pressed to spool downwards through connecting rod and the pressure spring that is located on the connecting rod, and being tightly connected of sleeve and valve core case all realized through C type metal o-ring and block in the upper and lower part of sleeve.The sealing principle of modulating valve as shown in Figure 1 is: valve rod 13 moves downward; Drive valve core case to pressing down spool, spool is to pressing down valve seat, and valve seat contacts with spool; Valve rod move downward the downward pressure that produces then for pressure spring 7; The pressure spring pressurized shrinks, and forms the sealing between valve core case and the spool through a C type metal o-ring, and this is a primary seal; The downward pressure of valve rod further drives flap and covers 11 downwards, realizes the sealing between sleeve and the valve core case through the 2nd C type metal o-ring and the 3rd C type metal o-ring, and this is a secondary seal.
Modulating valve in this example is the mazy type flow control valve; But the sealing configuration of the utility model is not limited to this kind modulating valve; In order on the basis that guarantees sealing effect, to make modulating valve satisfy the needs of carrying high temperature fluid; When the sealing of carrying out spool and valve core case, valve core case and sleeve, can adopt the mode of C type metal o-ring to seal for the modulating valve of any kind of, make that to be used for the C type metal o-ring application that balanced type seals originally more extensive.
The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Every technical spirit according to the utility model all still belongs to the protection domain of the utility model technological scheme to any simple modification, equivalent variations and modification that above embodiment did.
