Abstract
The utility model relates to an improved generation bonnet thread connection mode flanged gate valve, including valve body, valve gap, valve rod, valve mother, hand wheel and valve plate, the lower tip of valve gap is connected with the axle center with the upper end of valve body, and the valve body adopts threaded connection with the valve gap, the tip that a tip of valve rod penetrated the flashboard in valve mother, valve gap and the valve body is connected, and another tip of valve rod sets up hand wheel and valve rod fastening nut, and hand wheel is pinned at another tip of valve rod to the fastening of valve rod fastening nut, and parallel the system has three annular at the female valve rod outer fringe interval that corresponds of valve, inlays the dress sealing washer in three annular respectively. The application provides a valve in the technique that improved generation bonnet thread connection mode flanged gate valve will have now connects and has left out, directly adopts a valve mother sealed with the upper end of valve gap, saves the accessory, and this application unites two into one female the connecing with the valve of valve, only process when putting into production produce an accessory can, save the time cost, the material cost that produce the valve and connect.
Description
Technical field
The utility model belongs to valve field, is a kind of modified flange sluice valve with screw connected valve cover.
Background technology
Flanged gate valve is that connected mode is the gate valve of flange, and this connected mode is the most common. Flanged gate valve is at pipeReliable and stable while use in road, so often adopt flanged gate valve on pressure duct. The direction of motion of flashboard and streamBody direction is perpendicular, and gate valve can only be made standard-sized sheet and complete shut-down, can not make adjustments and throttling. Flashboard has two sealingsFace, two sealing surfaces of the most frequently used pattern slide valve form wedge shape, key groove is different with valve parameter, logicalBe often 5 °, medium temperature can be 3 ° when not high. The flashboard of Wedge Gate Valves can be made an entirety, is calledRigidity flashboard; Also can make the flashboard that can produce micro-deformation, to improve its manufacturability, make up sealing surfaceThe deviation that angle produces in process, this flashboard is called flexible disc.
By retrieval, find that following patent documentation and the application's correlation are larger, particular content is as follows:
CN2580226A discloses a kind of flange sluice valve with screw connected valve cover, and the upper end of valve body arranges internal threadAnd seam, the bottom of valve gap arranges external screw thread, and the bottom of valve gap is connected with the upper end concentric of valve bodyConnect, valve body adopts and is threaded with valve gap; The bottom of valve gap arranges the edge of a wing, and the bottom on the edge of a wing arranges seam;The upper end of valve gap arranges external screw thread, and the bottom that valve connects arranges internal thread, the upper end of valve gap and valve connect underEnd concentric is connected, and valve connects with valve gap lid and adopts and be threaded; The upper end that valve connects arranges external screw thread, valveFemale bottom arranges internal thread, and the upper end that valve connects is connected with valve mother's bottom concentric, and valve connects and valveFemale employing is threaded; One end of valve rod penetrate valve mother, valve connect with valve gap and valve body in the end phase of flashboardConnect, the other end of valve rod arranges handwheel and valve rod clamp nut, and valve rod clamp nut is fastened on valve rodHandwheel is pinned in the other end.
The application has carried out larger improvement on the basis of above-mentioned patent, has obtained good effect.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide that a kind of cost is low, good seal performance,The convenient modified flange sluice valve with screw connected valve cover of installing.
The technical scheme that the utility model is realized object is as follows:
A kind of modified flange sluice valve with screw connected valve cover, comprises valve body, valve gap, valve rod, valve mother, handwheelAnd valve plate, the bottom of valve gap is connected with the upper end concentric of valve body, and valve body and valve gap adopt screw thread to connectConnect; The bottom of valve gap arranges the edge of a wing, and the bottom on the edge of a wing arranges seam; The upper end of valve gap arranges external screw thread,Valve mother's bottom arranges internal thread, and the upper end of valve gap is connected with valve mother's bottom concentric, valve gap withThe female employing of valve is threaded; One end of valve rod penetrates valve mother, valve gap is connected with the end of the flashboard in valve body,The other end of valve rod arranges handwheel and valve rod clamp nut, and valve rod clamp nut is fastened on the other end of valve rodPin handwheel, be shaped with three annular grooves in the female corresponding valve rod outer rim spaced and parallel of valve, embedding respectively in three annular groovesDress sealing ring.
And, be shaped with three fins in the coaxial one in outer rim interval of the female upper end of valve.
The beneficial effects of the utility model are:
The modified flange sluice valve with screw connected valve cover that the application provides is by existing technology (CN2580226A)In valve connect and omitted, directly adopt a valve mother by the upper end sealing of valve gap, its effect is embodied in:
1, save accessory, by valve, female and valve connects and unites two into one the application, and in the time of production, one of a processing is joinedPart, saves and produces time cost, the material cost that valve connects.
2, simplify installation procedure, valve has no longer been installed and is connect and saved the valve installation time, reduced workman's laborFatigue resistance.
3, improved sealing effectiveness, this examination adopts upper, middle and lower-ranking seal with elastometic washer valve rod and valve mother,Improve the sealing property of valve.
Brief description of the drawings
Fig. 1 is the application's structural representation;
Fig. 2 is valve mother's top view.
Detailed description of the invention
Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail, and following examples onlyBeing descriptive, is not determinate, can not limit successively protection domain of the present utility model.
A kind of modified flange sluice valve with screw connected valve cover, comprise valve body 1, valve gap 3, valve rod 4, valve mother 5,Handwheel 8 and flashboard 2, the bottom of valve gap is connected with the upper end concentric of valve body, and valve body and valve gap are adoptedWith being threaded; The bottom of valve gap arranges the edge of a wing, and the bottom on the edge of a wing arranges seam; The upper end of valve gap arrangesExternal screw thread, valve mother's bottom arranges internal thread, and the upper end of valve gap is connected with valve mother's bottom concentric,Valve gap is threaded with female employing of valve, between valve gap and valve mother, sealing ring 6 is installed; One end of valve rod penetrates valveFemale, valve gap is connected with the end of the flashboard in valve body, and the other end of valve rod arranges handwheel and valve rod fastening screwMother 9, valve rod clamp nut is fastened on the other end of valve rod and pins handwheel.
The application's important innovations point is that described valve sealing means female and valve rod is:
