The utility model relates to the field of sleeve regulating valves, and in particular to a soft-sealed sleeve regulating valve. It comprises a valve body, a valve body sealing ring, a sleeve, a valve core and an O-ring, wherein the sleeve is arranged in the valve body, the valve core is arranged in the sleeve, the valve body sealing ring is arranged between the valve core and the sleeve, and the O-ring is arranged between the valve body and the sleeve. A groove is arranged inside the sleeve, the O-ring is arranged in the groove, and the inner ring of the O-ring is in compression contact with the valve core. The utility model improves the leakage level of the sleeve regulating valve from the original IV level to VI level by improving the sleeve structure, effectively improving the leakage level of the whole machine, and can meet the use of most working conditions.
Description
Technical Field
The utility model relates to the field of sleeve regulating valves, in particular to a soft sealing sleeve regulating valve.
Background
Because the sleeve regulating valve core and the sleeve are of a hard sealing structure between inclined planes, grinding is needed during assembly, the leakage grade is only IV at present, and the requirements of some working conditions requiring high leakage grade are hardly met.
Disclosure of Invention
In order to solve the problem that the leakage grade cannot meet the requirement due to the fact that the inclined surface is sealed firmly between the valve core of the sleeve adjusting valve and the sleeve, the utility model provides the soft sealing sleeve adjusting valve, a groove is additionally arranged in the sleeve, a fluororubber O-shaped sealing ring is arranged, a soft sealing structure is additionally arranged on the basis of the original hard sealing between the valve core and the sleeve, the leakage grade of the whole machine is effectively improved, and most of working conditions can be met.
The technical scheme adopted by the utility model is as follows: the utility model provides a soft seal sleeve governing valve, includes the valve body, valve body sealing washer, sleeve, case and O type sealing washer, the sleeve sets up in the valve body, the case sets up in the sleeve, the valve body sealing washer sets up between case and sleeve, sets up O type sealing washer between valve body and sleeve.
Further, a groove is formed in the sleeve, an O-shaped sealing ring is arranged in the groove, and an inner ring of the O-shaped sealing ring is in compression contact with the valve core.
In the above technical scheme, the O-shaped sealing ring is made of fluororubber.
The beneficial effects of the utility model are as follows: through improving sleeve structure, install fluororubber O shape sealing washer additional in sleeve inside for need not grind when sleeve and case assembly also can improve sleeve governing valve's leakage level from original IV level to VI level, the effectual leakage level that improves the complete machine can satisfy most operating mode and use.
Drawings
FIG. 1 is a block diagram of the present utility model;
Fig. 2 is an enlarged view of part of i in fig. 1.
In the figure: the valve comprises a 1-valve body, a 2-valve body sealing ring, a 3-sleeve, a 3-1-groove, a 4-valve core and a 5-O-shaped sealing ring.
Detailed Description
The utility model is further described below with reference to the accompanying drawings.
The soft sealing sleeve regulating valve shown in fig. 1 comprises a valve body 1, a valve body sealing ring 2, a sleeve 3 and a valve core 4,O. The O-shaped sealing ring 5 is made of fluororubber O-shaped sealing ring conforming to GB1235-76, an annular groove 3-1 is formed in the upper portion of the inner wall of the sleeve 3, the valve body sealing ring 2 is placed on a step of a central hole of the valve body 1, the sleeve 3 with the annular groove 3-1 is placed in the valve body 1, the sleeve 3 is pressed tightly to the valve body sealing ring 2, the O-shaped sealing ring 5 is placed in the annular groove 3-1, finally a valve core is installed in the sleeve 3, and the sleeve 3 and the O-shaped sealing ring 5 are in compression contact to form a soft sealing structure, so that the leakage level of the valve is improved. The leakage grade of the sleeve regulating valve is improved from the original IV grade to the VI grade.
