Description
Technical field
The utility model relates to a kind of valve, and more particularly, it relates to a kind of hand sluice valve.
Background technique
Gate valve (gate valve) is an open-shut device flashboard, and moving direction and the flow direction of flashboard are perpendicular, and wear-resistant hand sluice valve can only make standard-sized sheet and complete shut-down, uncomfortable door parameter and different, is generally 5 °, be 2 ° 52 when medium temperature is not high '.Improve its manufacturability, make up the deviation that sealing surface angle produces in course of working, this flashboard is called Flexible disc.
At present, (application number is that the Chinese patent of CN201020201003.9 discloses the anticorrosive gate valve of a kind of high temperature resistance to erosion) on market, it comprises gate valve, gate valve is formed primarily of valve body, flashboard, valve rod, valve gap, handwheel, before flashboard, on medium contact face, heap is welded with hard alloy layer, on rear medium contact face, also heap is welded with hard alloy layer, and sealing surface is designed to whole plane, the also surfacing hard alloy layer in the lower end of flashboard; Be provided with dust-proof cover being positioned at the position that leaks outside of the valve rod above handwheel, dust-proof cover is made up of the Stainless Steel Tube of an end closure, and dust-proof cover is arranged on valve rod support, and what cover on valve stem top leaks outside on position; At the valve rod of valve rod support and the valve gap position that leaks outside, tubulose dust-proof cover is installed; Be provided with sink at valve gap, sink is made up of one group of radiating fin, and one group of radiating fin is welded on valve gap.
As gate valve, one end of valve rod is connected with Spool rotating, rotation hand wheel makes valve rod rise, declines, thus drive valve core movement to play the effect of unlatching, closing gate valve by valve rod, and one end of valve rod constantly rubs with spool in the process of band movable valve plug, cause the contact jaw of valve rod, spool to occur wearing and tearing, cause the stroke of spool not enough, make gate valve occur leaking.
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of valve rod anti abrasive wear-resistant hand sluice valve.
For achieving the above object, the utility model provides following technological scheme: a kind of wear-resistant hand sluice valve, comprise valve body, described valve body top is provided with valve gap, and described valve gap is equipped with valve rod, and described valve rod and valve gap rotate and link, also spool is provided with in described valve body, one end that described valve rod stretches into valve body is linkage portion, and described linkage portion is connected with Spool rotating, wherein: described linkage portion and valve rod removably connect.
By adopting technique scheme, described linkage portion and valve rod removably connect, when linkage portion Long-Time Service, with spool wear and tear for a long time, dismounting and change linkage portion can be passed through, thus ensure that spool has enough strokes, ensure the sealability of gate valve, extend the working life of described gate valve.
The utility model is set to further: described valve rod offers axial tapped hole towards one end of spool, and described linkage portion is provided with outside thread, and described linkage portion is connected with threaded stem.
By adopting technique scheme, make described linkage portion simple, convenient, be effectively connected with valve rod.
The utility model is set to further: the hand of spiral of described tapped hole is contrary with the opening direction of valve rod.
By adopting technique scheme, ensureing that described valve rod not only can not drive the screw connection structure in linkage portion during the course, more can reinforce being threaded of linkage portion and valve rod, the connection tightness effectively between guarantee linkage portion and valve rod.
The utility model is set to further: described valve rod is provided with rubber wear-resisting layer towards the end face of one end of spool.
By adopting technique scheme, at linkage portion and valve rod constantly mutually in fastening effect situation, described rubber wear-resisting layer effectively prevents linkage portion or valve rod from occurring plastic deformation, prevents linkage portion or valve rod from occurring wearing and tearing, effectively extends the working life of linkage portion, valve rod.

Embodiment
Referring to figs. 1 through Fig. 3, the wear-resistant hand sluice valve embodiment of the utility model is described further.
A kind of wear-resistant hand sluice valve, comprise valve body 1, described valve body 1 top is provided with valve gap 2, described valve gap 2 is equipped with valve rod 3, described valve rod 3 rotates with valve gap 2 and links, spool 4 is also provided with in described valve body 1, one end that described valve rod 3 stretches into valve body 1 is linkage portion 5, the one end extended in outside valve body 1 is then connected with handwheel 6, described linkage portion 5 is rotatably connected with spool 4, valve body 1 is separated into inlet part 9 and outlet part 10 by described spool 4, wherein: described linkage portion 5 removably connects with valve rod 3, this preferably described valve rod 3 of removably connecting offers axial tapped hole towards one end of spool 4, described linkage portion 5 is provided with outside thread, described linkage portion 5 is threaded with valve rod 3.
Principle of the present utility model is: described linkage portion 5 removably connects with valve rod 3, when linkage portion 5 Long-Time Service, wear and tear for a long time with spool 4, dismounting and change linkage portion 5 can be passed through, thus ensure that spool 4 has enough strokes, ensure the sealability of wear-resistant hand sluice valve, extend the working life of described wear-resistant hand sluice valve.
In order to ensure the connective stability between linkage portion 5 and valve rod 3, the hand of spiral of described tapped hole is contrary with the opening direction of valve rod 3, ensure that described valve rod 3 not only can not drive the screw connection structure in linkage portion 5 during the course, more can reinforce being threaded of linkage portion 5 and valve rod 3, effectively ensure the connection tightness between linkage portion 5 and valve rod 3.
As the further optimization of technological scheme, described valve rod 3 is provided with rubber wear-resisting layer 11 towards the end face of one end of spool 4, in the constantly mutual fastening effect situation of linkage portion 5 with valve rod 3, described rubber wear-resisting layer 11 effectively prevents linkage portion 5 or valve rod 3 from occurring plastic deformation, prevent linkage portion 5 or valve rod 3 from occurring wearing and tearing, effectively extend the working life of linkage portion 5, valve rod 3.
Finally, in order to ensure that the connection between linkage portion 5 and valve rod 3 ensures fastening, as shown in Figure of description 3, valve rod 3 is offered the fastener hole 7 just right with the male thread portion in linkage portion 5, fixing further by being selected into Cock screw 8 in fastener hole 7, locking described linkage portion 5, prevent the connection between linkage portion 5 and valve rod 3 from loosening.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
