Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
A kind of fluorine lining butterfly valve, shown in Fig. 1 and Fig. 2, including valve body 1, valve rod 2 and butterfly plate 3, valve body 1 offers water supply The passage 11 flow through, butterfly plate 3 is arranged in this passage 11, butterfly plate 3 for circular slab with passage 11 in being coaxially disposed.Valve rod 2 wears The upper end of valve body 1 is connected with butterfly plate 3, and the connection fixed above at valve body 1 has mounting shell 7, is provided with driving in mounting shell 7 Mechanism, drive mechanism includes that, in the worm gear being meshed and worm screw, wherein worm gear is in being horizontally disposed with, and valve rod 2 deviates from butterfly plate 3 one end connection Being automatically connected in the middle part of worm gear, worm screw coordinates in the side of worm gear.By driving rotation that worm gear wheel, valve rod 2 can be driven to be subject to Being in linkage with worm gear to rotate in fixed axis, butterfly plate 3, under the driving force of valve rod 2, can rotate in through hole 5, and its scope rotated is 0 In spending ~ 90 degree, then in the range of this, control butterfly plate 3 opens and closes fluorine lining butterfly valve.
Arranging connection outside mounting shell 7 has expansion link 8, worm screw one end to wear mounting shell 7, expansion link 8 one end and worm screw Wearing end to be connected, the other end of expansion link 8 is connected to the middle part of handwheel 9, by stretching or retraction expansion link 8 so that Close or the remotely mounted shell 7 of handwheel 9, the present embodiment is installed in the duct, controls to open and close when staff needs to operate butterfly valve During pipeline, can be by stretching expansion link 8 so that handwheel 9 is away from valve body 1, after handwheel 9 is distance away with valve body 1, work Personnel pinch hold handwheel 9 rotate time be not easy to collide pipeline, it is possible to reach to facilitate rotating effect;And can after operation terminates To make expansion link 8 shrink towards valve body 1 direction Level Promoting handwheel 9, expansion link 8 bounces back, and handwheel 9 is after valve body 1, permissible Reduce taking up room of butterfly valve.
Shown in Fig. 3, when the fluid pressure ratio in pipeline is bigger, in the easy deformation of butterfly plate 3, especially butterfly plate 3 Bottom, when fluid has just enter in pipeline, usually can first impact the lower section of butterfly plate 3, thus cause the bottom of butterfly plate 3 first to occur Deformation, the sealing effectiveness between butterfly plate 3 and valve body 1 after deformation it cannot be guaranteed that.For this problem, the present embodiment is at butterfly plate 3 Side stretches out and is provided with installation portion, and installation position is in the diametric(al) of butterfly plate 3, and installation portion is shaped in butterfly plate 3, butterfly plate 3 connect valve rod 2 by installation portion realizes and the removably connecting of valve rod 2.The diametric(al) being parallel to butterfly plate 3 on installation portion is opened Being provided with through hole 5, through hole 5 can coordinate with valve rod 2, radially offers draw-in groove 6 in through hole 5 simultaneously, and at valve rod 2 Outer wall integrally formed with draw-in groove 6 in being embedded the fixture block 4 coordinated, wherein draw-in groove 6 is dovetail groove;The also bottom at through hole 5 is offered There is circular groove 51, wear the end, one end into through hole 5 integrally formed with the projection coordinated in inlay card with groove 51 at valve rod 2 21.Fixture block 4 being directed at draw-in groove 6, promotes valve rod 2 to wear into through hole 5, when fixture block 4 all blocks and is embedded in draw-in groove 6, projection 21 strikes Well also it is embedded in groove 51, achieves valve rod 2 by the cooperation of draw-in groove 6 and fixture block 4 radially fixed in butterfly plate 3, pass through projection 21 and groove 51 to achieve valve rod 2 two times radially fixed in butterfly plate 3 so that both compact siro spinning technology, during rotation valve rod 2, Butterfly plate 3 can be crossed and rotate in passage 11.
Shown in Fig. 4, when the present embodiment is arranged in the duct, butterfly plate 3 connect valve rod 2 side be butterfly valve go out liquid Mouthful, opposite side is inlet, during in order to prevent the liquid entered to be attached on butterfly plate 3 with sticky contaminant thus corrode butterfly plate 3, The side deviating from valve rod 2 at butterfly plate 3 is provided with drainage screen 10, and drainage screen 10 can be crossed be blocked in butterfly plate by fixing impurity in fluid The outside of 3, thus play the effect preventing solid impurity to be fitted in butterfly plate 3.
This specific embodiment is only that it is not to restriction of the present utility model, ability to explanation of the present utility model The present embodiment can be made after reading this specification by field technique personnel as required does not has the amendment of creative contribution, but As long as all being protected by Patent Law in right of the present utility model.
