Description
Technical field
This utility model is related to a kind of valve, and specifically, it is related to a kind of stop valve.
Background technology
Stop valve（stop valve,Globe Valve）Opening and closing element be stopper flap, sealing is above in plane or sea
The conical surface, flap is for linear motion along the centrage of valve seat, the forms of motion of valve rod,（Adopted name：Dark bar）, also there is lifting rotation
Rod-type can be used to control empty gas and water, steam, various Korrosionsmediums, mud, oil product, liquid metal and radiating medium etc. respectively
The flowing of type fluid, therefore, such stop valve valve that dams is highly suitable as cutting off or adjusting and throttle
With, due to the valve rod of such valve, to be turned on and off stroke relatively short, and with very reliable cutting function, and due to
The change of valve seat port and the stroke direct proportionality of flap, are very suitable for the regulation to flow.
Existing technology is suffered from the drawback that：
1st, fluid resistance is big, and required power is larger during opening and closing；
2nd, it is not suitable for granule, viscosity is larger, easy coking medium；
3rd, regulation performance is poor.
The content of the invention
Goal of the invention：In order to overcome the problem of conventional generation, this utility model to provide a kind of stop valve.
Technical scheme：This utility model discloses a kind of stop valve, including valve body, guide rod, valve seat, flap, valve rod, flap
Lid, spirotallic gasket, upper seal support, stud, nut, flexible graphite packing, filler pressing sleeve, hold-down grid, valve stem nut, screw,
Handwheel, valve body is connected with valve seat, and seat bottom portion centre position is provided with guide rod, and valve seat is connected with flap, flap inner side and valve rod
Connection, the bottom outside of valve rod is fixed by valve clack cover, and the mid portion of valve rod is fixed by stud, and stud is connected with nut, nut
It is connected with upper seal support, flexible graphite packing is provided with the top of stud, flexible graphite packing is connected with filler stone set, filler stone set
It is connected with hold-down grid, hold-down grid has nut to fix, valve rod upper end is connected with valve stem nut, valve stem nut and mode connects for screw,
Valve stem tip is connected with handwheel, and handwheel is fixed with valve rod by nut, and the bottom of nut is provided with packing ring, and this utility model uses the longevity
Life length, reduces maintenance frequency, reduces operating cost, robust Seal Design, it is ensured that the zero leakage of valve rod, there is provided without the need for dimension
The condition of shield.
Further, valve body adopts plastic material, environment friendly and pollution-free.
