Abstract

The present invention provides an expansion gate valve which is composed of a valve body, a valve cover, a valve stem, a valve stem bracket, a bearing bracket, a valve core and a valve plate, wherein the valve core and the valve plate are connected by a dovetail structure and are arranged in the valve body and the valve cover, the lower end of the valve stem is connected with the valve core through screw threads, the upper part of the valve stem is connected with the upper part of the valve cover by the bearing bracket, the valve stem bracket and a sealing press cover, the lower end of the valve cover is fixed with the lower end of the valve body together by a flange bolt screw bolt, and a hand wheel is connected with the upper end of the valve stem. Compared with the prior art, the expansion gate valve of the present invention has the characteristics of reasonable design, easy machining, flexible opening and closing, convenient operation and use, reliable seal, long service life, reduction of many trouble such as air stop and water stop of pipelines, etc. because the valve is overhauled and replaced, etc. Thus, the present invention has good popularization and use value.

Description

Expansion sluice valve
1, technical field
The present invention relates to a kind of pipeline valve processing technique, specifically a kind of expansion sluice valve.
2, technical background
The pipeline valve of known technology mainly divides gate valve, stopcock and ball valve etc., the in use existing deficiency of above-mentioned pipeline valve is that sealing is poor, between valve plate and the valve body mutually friction to have reduced the whole service life of valve low, open and close dumbly in addition in addition, be difficult to the automation control of pipeline etc.In actual applications, because processing technique and structure is unreasonable, employed various gate valves in the oil gas conveying in town water supply, air feed, oil field and the equipment of oil-refining chemical enterprise, just mean stopping production as long as valve overhauled or change, especially chemical enterprise, in order to guarantee the production safety operation, use low-quality valve not only will waste a large amount of financial resources, manpower, the more important thing is the safety that can have influence on production.To the normal life of the maintenance of city pipeline valve or the direct image of replacing meeting to the resident.Up to the present, the expansion sluice valve that have high leak tightness, does not have machinery wearing and tearing, a long service life does not also have bibliographical information and product to ask the city.
3, goal of the invention
The purpose of this invention is to provide a kind of good airproof performance, fluid medium fast shut-off, open and close flexibly, do not have mechanical wearing and tearing, long service life, easy to operate expansion sluice valve.
The objective of the invention is to realize in the following manner, the centre of spool is provided with screw thread and valve rod joins, spool moves up and down by the rotation of valve rod, the vertical section of spool is taper, pass through the valve plate on dovetail groove connecting band inclined-plane in the both sides of spool, be inlaid with seal ring on the face that the inwall of valve plate and valve body joins.The working principle of closing valve during use is: when valve rod rotates when promoting the spool band and valve plate and move down into the bottom of valve body, section is that the spool of taper just begins to promote valve plate and moves horizontally and draw close the turnover that compresses valve body to valve interior wall and close.When driving valve, rotary valve rod, valve rod drive on the spool and move, and valve plate prolongs the inclined-plane that joins with spool by dovetail groove to be made level earlier and shrink and separate with valve body, moves in the continuation along with spool, and valve plate and spool one the same moving all connect the import and export of valve body.
Accompanying drawing 1 is the overall structure schematic representation of expansion sluice valve;
Accompanying drawing 2 is that the A-A of expansion sluice valve valve body, spool and valve plate is to the cross-sectional configuration schematic representation.
4, description of drawings
Explain below with reference to Figure of description expansion sluice valve of the present invention being done.
Expansion sluice valve of the present invention, as accompanying drawing 1, shown in 2, its structure is by valve body 3, valve gap 9, valve rod 7, valve rod support 11, bearing bracket 10, spool 5, valve plate 4 constitutes, spool 5 and valve plate 4 are connected by the dovetail structure and are arranged among valve body 3 and the valve gap 9, the lower end of valve rod 7 and spool 5 join by screw thread, the top of valve rod 7 is by bearing bracket 10, valve rod support 11 and sealing gland 12 join with the top of valve gap 9, the upper end of the lower end of valve gap 9 and valve body 3 by flange bolt bolt admittedly together, in the middle of bearing bracket 10 and the valve rod support 11 bearing 14 is set, 15 join with valve rod 7, and handwheel 13 is connected on the upper end of valve rod.
As shown in Figure 1, the centre of spool 5 has perpendicular screwed hole, the both sides of spool 5 are processed with two narrow down wide inclined-planes, the dovetail groove that the inclined-plane is provided with on dovetail and the valve plate 4 joins identical, valve plate 4 is provided with O-ring seal 17 with the face that valve body 3 joins, and also is provided with the elasticity shrinking device of being made up of spring 6, spring housing 18 and spring capping 19 on the top of spool 5 and valve plate 4.
As shown in Figure 1, at the bottom of the bottom of valve body 3 is provided with valve 2,2 centre is provided with the bolt 1 that discharges water at the bottom of the valve, and 2 top is provided with valve plate holder lid 16 at the bottom of the valve.
5, mode of execution
Its processing and fabricating of expansion sluice valve of the present invention is very simple and convenient, shown in the by specification accompanying drawing routinely the process for machining processing and fabricating of processing and fabricating gate and valve get final product.
Expansion sluice valve of the present invention uses operation also very simple and convenient, during use, by the handwheel rotation valve rod, the screw thread on the screw thread of valve rod lower end and spool top joins and drives the spool oscilaltion, when the needs Open valve, rotate counterclockwise handwheel, spool moves up, and valve plate shrinks to the centre along the inverted cone inclined-plane of spool both sides and separates with the inwall of valve body, valve plate leaves valve port, along with moving on the spool, valve plate is in company with the top that moves to valve body on the spool, and valve just is in open mode; When closing, clockwise rotate handwheel, spool drives valve plate and moves down, and when valve plate moved to the valve body bottom, valve plate was stifled tight with the turnover sealing valve port on the valve body under the thrust of inverted cone spool expands.
Expansion sluice valve of the present invention can be used for various in the conveying and the cut-out of flowing medium under the low temperature because this valve is in opening-closing process, there are not mechanical friction in valve plate and valve body, thereby be more than ten times of common valve working life.
Expansion sluice valve of the present invention is compared with prior art, have reasonable in design, be easy to processing, open and close flexible, easy to operate, sealing is reliable.Owing to do not have friction between valve plate and the valve body, thereby, there is not the valve plate wear phenomenon of traditional gate valve, the whole service life of valve is prolonged greatly, the more important thing is to have reduced because of maintenance and change many troubles such as valve stops the supple of gas or steam pipeline to cut off the water, thereby, have good value for applications.
