Abstract
The utility model is related to a kind of High Pressure Difference pilot valve part of regulating valve, is mainly used in High Pressure Difference pilot valve.Including valve rod, pin, pilot valve, disc spring, main valve plug, nut, it is characterised in that：Also include disc spring pad；Main valve plug is ring-type, and two annular protrusions of diameter of different sizes are provided with the dividing plate in the chamber of main valve plug upper end, and several balance pipes are equidistantly provided with the ring-type platform in minor diameter annular protrusion, and main valve plug lower end is equidistantly provided with six raised valves.Valve rod is connected by pin with pilot valve one end, and disc spring pad is arranged in disc spring, and in main valve plug, the pilot valve other end sequentially passes through the disc spring equipped with disc spring pad, main valve plug minor diameter annular protrusion to disc spring, is fixed on main valve plug by nut.Advantage is：When pilot valve is opened, the pressure medium that balance pipe makes to act on main valve plug on main valve plug is reduced rapidly, so when pressure difference before and after valve increases, valve can be with normally-open, it is adaptable to High Pressure Difference pilot valve.
Description
Technical field
The utility model is related to a kind of High Pressure Difference pilot valve part of regulating valve, is mainly used in High Pressure Difference pilot valve.
Background technology
At present, there is the occasion in High Pressure Difference, valve in the fields such as oil, chemical industry, in universal pilot valve product
Cannot be normally-open.
The content of the invention
In view of above-mentioned existing technical problem, a kind of High Pressure Difference pilot valve core of the utility model there is provided regulating valve
Part, when pressure difference before and after valve increases, valve can be with normally-open.
To achieve the above object, the technical scheme for being used is the utility model：A kind of High Pressure Difference guide of regulating valve
Valve hole part, including valve rod, pin, pilot valve, disc spring, main valve plug, nut, it is characterised in that：Also include disc spring pad；
The main valve plug is ring-type, and two convex annulars of diameter of different sizes are provided with the dividing plate in the chamber of main valve plug upper end
Rise, several balance pipes are equidistantly provided with the ring-type platform in minor diameter annular protrusion, main valve plug lower end is equidistantly provided with six projections
Valve；
Valve rod is connected by pin with pilot valve one end, and disc spring pad is arranged in disc spring, and disc spring is mounted in main valve plug, guide
The valve element other end sequentially passes through the disc spring equipped with disc spring pad, main valve plug minor diameter annular protrusion, and main valve plug is fixed on by nut
On.
Advantage of the present utility model is：When pilot valve is opened, balance pipe makes to act on Jie on main valve plug on main valve plug
Matter pressure is reduced rapidly, so when pressure difference before and after valve increases, valve can be with normally-open, it is adaptable to High Pressure Difference pilot valve.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of the utility model main valve plug.
Specific embodiment
As shown in Figure 1, 2, a kind of High Pressure Difference pilot valve part of regulating valve, including valve rod 1, pin 2, pilot valve 3,
Disc spring 4, main valve plug 6, nut 7, also including disc spring pad 5.
Main valve plug 6 is ring-type, and two convex annulars of diameter of different sizes are provided with the dividing plate in the upper end chamber of main valve plug 6
Rise, several balance pipe 6-3 are equidistantly provided with the ring-type platform in minor diameter annular protrusion 6-1, the lower end of main valve plug 6 is equidistantly provided with six
Individual raised valve 6-4.
Valve rod 1 is connected by pin 2 with the one end of pilot valve 3, and disc spring pad 5 is socketed in disc spring 4, and disc spring 4 is mounted in into main valve
On major diameter annular protrusion 6-2 in the chamber of core 6, the other end of pilot valve 3 is sequentially passed through into the disc spring 4 equipped with disc spring pad 5, master
Minor diameter annular protrusion 6-1 in the chamber of valve element 6, is fixed on main valve plug 6 by nut 7.
Valve rod 1, pin 2, pilot valve 3 and main valve plug 6 are stainless steel.
When pilot valve 3 is opened, several balance pipe 6-3 make the pressure medium acted on main valve plug 6 fast on main valve plug 6
Prompt drop is low, so when pressure difference before and after valve increases, valve can be with normally-open, it is adaptable to High Pressure Difference pilot valve.
