Abstract
The utility model relates to a flat-plate gate valve, which comprises a valve body, a valve stem, a gate plate and a hand wheel. The two ends of the valve stem are respectively connected with the connection end of the gate plate and the hand wheel. The valve body is formed by a medium passage and a holding chamber. In the holding chamber, a valve stem supporting seat is arranged on the outer wall of the medium passage, a nut seat is arranged at the connection end of the gate plate and a valve stem nut is arranged in a nut seat chamber; the valve stem nut is sheathed on the body of the valve stem and the end part of the valve stem is ejected against the valve stem supporting seat; and the other end of the valve stem is fixedly connected with the hand wheel. The utility model has the advantages that good valve stem stability, good sealing performance, flexible opening and closing and compact structure.
Description
[technical field]
The utility model belongs to a kind of plate valve.
[background technique]
At present, the valve rod of plate valve all exposes outside valve body, and an end connects with the handwheel screw-thread fit, and the connecting end of the other end and flashboard is direct-connected.There is following problem in the plate valve of this structure: the one, and the valve rod poor stability.Valve rod connects with the handwheel screw-thread fit, and the gap is big, and the other end and flashboard are direct-connected, and swing is big, and therefore, when throttle down, valve rod and flashboard are very easily crooked, causes handwheel rotation difficulty even damages valve.The 2nd, physical dimension is big, narrow application range.The 3rd, seal structure complex is easy to generate and leaks and the switch difficulty.
[summary of the invention]
For overcoming the problems referred to above that prior art exists, the utility model aims to provide a kind of plate valve, and this gate valve has good stability, sealability height, compact structure and advantage applied widely.
For achieving the above object, the utility model has adopted following technological scheme, this construction of parallel gate valve, comprise valve body, valve rod, flashboard, handwheel, the valve rod two ends are connected with handwheel with the flashboard connecting end respectively, it is characterized in that: described valve body is made of two-part, and a part forms medium channel, another part forms holding cavity, and valve rod, flashboard connecting end are located in the holding cavity; In holding cavity, the outer wall of medium channel is provided with the valve rod supporting base, and the flashboard connecting end is provided with a nut seat, and nut seat is provided with Stem Mut in the chamber; Described Stem Mut is set on the valve rod shaft, and the valve rod end withstands on the described valve rod supporting base; The other end of valve rod is fixedlyed connected with handwheel.
Beneficial effect: compared with prior art, the utility model is designed to two-part with valve body, makes a part of valve pocket as medium channel, and another part then forms the holding cavity of valve rod and flashboard connecting end, and the plate valve that changes exposed valve rod is a dark rod flat plate gate valve.The valve rod two ends, one end is fixedlyed connected with handwheel, the other end is then by valve rod supporting base, nut seat and Stem Mut structure thereof, realize that feed screw nut's formula connects, during operation, utilize the lifting of Stem Mut on the valve rod shaft, drive the flashboard switch, reached the valve rod good stability, switch flexibly and the purpose of compact structure.Moreover, adopt dark bar structure after, can omit sealing configuration of the prior art again, adopt O shape rubber seal to realize the holding cavity sealing, simple in structure, sealing reliability good.
[description of drawings]
Fig. 1 is an embodiment's of the utility model a sectional structure schematic representation.
Among the figure: handwheel 1, rubber seal 2, valve rod 3, nut seat 4, Stem Mut 5, valve rod supporting base 6, flashboard 7, flashboard connecting end 71, medium channel 81, holding cavity 82.
[embodiment]
Referring to Fig. 1.Valve body is by the pipeline that forms medium channel 81, and the housing two-part composition that forms holding cavity 82, and two-part are welded into integral body.The pipe ends that forms medium channel 81 is a connecting flange, and flashboard 7 radially is located on the medium channel 81, constitutes sealing pair with valve seat.Flashboard connecting end 71 passes tube wall and stretches in the holding cavity 82, and nut seat 4 is welded on the flashboard connecting end 71 admittedly, and Stem Mut 5 is built in the chamber of nut seat 4.After the shaft of valve rod 3 passed nut seat 4 and built-in Stem Mut 5 thereof, pushed up mutually with valve rod supporting base 6 its end.The structure of valve rod supporting base 6 is actually a solid axle sleeve that welds, and after the valve rod end diameter is dwindled, gets final product in the insertion axle sleeve, and valve rod 3 is played the position rotating effect.Fixedly connected with handwheel 1 in the upper end of valve rod 3, valve rod 3 adopts 2 sealings of O shape rubber seal with the sealing part of holding cavity 82.During operation, the rotation of handwheel 1 can make Stem Mut 5 lifting on the screw mandrel shaft of valve rod 3, thereby drives the nut seat 4 and the flashboard 7 of one with it, lifting in holding cavity 82, opening and closing gate valve.
