Abstract
The utility model relates to a wedge gate valve, which comprises a valve body, a gate plate, a valve rod, a middle flange gasket, a screw nut (5), a screw stud, a valve cover, a packing gasket, a packing material, a pin shaft, a screw bolt (11), a screw nut (12), a packing gland, a screw bolt (14), a screw cap, a bracket, a bearing, a valve rod screw nut, an oil cup, a bearing gland, a terminated screw, a hand wheel, a bearing sleeve, a nameplate and a locknut. The wedge gate valve is characterized in that: the gate plate is mounted at a middle chamber of the valve body, and the valve rod, the valve cover, the packing gasket, the packing material, the packing gland, the bracket, the valve rod screw nut, the bearing, the bearing sleeve, the hand wheel and the locknut are successively mounted; the valve body is fixedly connected with the valve cover through the screw stud and the screw nut (5); and the bracket is connected with the valve cover through the screw bolt (14). As the planar gate plate which is vertical to the flowing direction of a medium is arranged in the valve body, a passage of the medium is opened or closed through the ascending/descending of the gate plate. The structure is simplified and the sealability is improved. Thus, the wedge gate valve has the characteristics of simple and reliable structure, good sealability, small volume, light weight, lower cost of production, and the like.
Description
Technical field
The utility model belongs to the control of fluid circuit such as water, oil, gas and uses valve, particularly a kind of Wedge gate valve.
Background technique
Conventional Wedge gate valve comprises tape guide rib and fluid valve body, the valve gap into and out of the duct; Gland and be located at valve gap and Gland between the filler microcephaly of band filler chamber, stuffing box packing, T-shape valve rod and be located at the wedge-type flashboard (flap) of valve rod lower end and the handwheel of end provided thereon.This type of gate valve one is because fluid is cylindrical (straight-through type) duct into and out of the hole, corresponding flashboard and body cavity size are big, material expends many and use in required moment also bigger; The 2nd, between valve gap and Gland, establish a filler microcephaly independently, in order to axial restraint valve rod and filling stuffing box packing, both there had been complex structure, its sealing is relatively poor again.Therefore, above-mentioned gate valve exists that structure and processing technology are complicated, volume is big, consumptive material is many, sealing is relatively poor and the more high disadvantage of cost of production.
Summary of the invention
The purpose of the utility model is the defective that exists to background technique, improves a kind of Wedge gate valve of design, simplifies structure and processing technology to reach, and reduces consumptive material and valve weight and cost of production, improves sealing, reduces purposes such as valve volume.
The solution that realizes the utility model is:
A kind of Wedge gate valve comprises that valve body, flashboard, valve rod, middle flange gasket, nut, double-screw bolt, valve gap, Packing seat, filler, bearing pin, bolt, nut, Gland, bolt, spiral shell emit, support, bearing, Stem Mut, lubricating cup, bearing gland, stopping screw, handwheel, bearing housing, nameplate, locking nut; It is characterized in that: flashboard is contained in the valve body lumen, the valve rod of packing in succession, valve gap, Packing seat, filler, Gland, support, Stem Mut, bearing, bearing housing, handwheel, locking nut.Valve body is fixedly connected with double-screw bolt, nut with valve gap.Support, valve gap connect with bolt.
Further specify, described flashboard and valve body seal, and described valve rod plays valve gearing up and down, and described middle flange seals between valve body and valve gap.
A kind of Wedge gate valve, groundwork principle in valve body, establish one with MEDIA FLOW to the plane flashboard that becomes Vertical direction, lean on the up-down of this flashboard to open or close the path of medium.
The usefulness of the utility model is:
Because with flashboard design plane shape, and with MEDIA FLOW to becoming vertical, when Wedge gate valve was closed, plane flashboard and valve body sealed fully, opened or close the path of medium through the up-down of flashboard.Simplify the structure and improved sealing; Keying moment during it uses also can reduce 5～20%.Therefore, the utlity model has simple in structure, reliable, good airproof performance, characteristics such as volume is little, in light weight, and cost of production is lower.
