Abstract
The utility model discloses a non-pressure plate sparse-teeth type butterfly valve, which is provided with a valve body and a sparse-teeth type butterfly plate, wherein a valve shaft is arranged on the valve body, the sparse-teeth type butterfly plate is arranged in the valve body through the valve shaft, a valve body sealing ring is arranged on the inner circumference of the valve body, a matched butterfly plate rubber sealing ring is arranged on the outer circumference of the sparse-teeth type butterfly plate, the cross section of the butterfly plate rubber sealing ring is in a dovetail zigzag shape, a mounting groove capable of accommodating the dovetail zigzag butterfly plate rubber sealing ring is correspondingly arranged along the outer circumference of the sparse-teeth type butterfly plate, and the cross section of the mounting; drainage holes are uniformly distributed and communicated at intervals at the bottom of the dovetail zigzag mounting groove, and pressure guide holes communicated with the drainage holes are correspondingly formed in the plate surface of the thinning-tooth butterfly plate. For traditional sparse tooth formula butterfly valve, the utility model discloses a manufacturing cost is lower relatively, sealed effect is also better relatively.
Description
Technical Field
The utility model relates to a dredge tooth formula butterfly valve, specifically speaking relate to a tooth formula butterfly valve is dredged to non-pressure plate.
Background
The tooth-thinning butterfly valve in the prior art is provided with a valve body and a tooth-thinning butterfly plate, wherein a valve shaft is arranged on the valve body, the tooth-thinning butterfly plate is arranged in the valve body through the valve shaft, a valve body sealing ring is arranged on the inner circumference of the valve body, and a matched butterfly plate rubber sealing ring is arranged on the outer circumference of the tooth-thinning butterfly plate. According to the sparse-teeth butterfly valve in the prior art, the butterfly plate rubber sealing ring is arranged on the sparse-teeth butterfly plate through the pressing plate and the bolt, the butterfly plate rubber sealing ring is fixedly arranged, the sealing force between the butterfly plate rubber sealing ring and the valve body sealing ring matched with the butterfly plate rubber sealing ring is fixed, when the pressure of a fluid medium is large, a slight leakage phenomenon exists, and in addition, the butterfly plate rubber sealing ring is arranged through the pressing plate and the bolt, so that the manufacturing cost of the valve is relatively increased.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a relative lower, the sealed effect of manufacturing cost is better not have clamp plate and dredge tooth-like butterfly valve relatively.
In order to solve the technical problem, the utility model discloses a non-pressure plate sparse tooth formula butterfly valve has valve body and sparse tooth formula butterfly plate, is equipped with the valve shaft on the valve body, and sparse tooth formula butterfly plate is adorned in the valve body through the valve shaft, has the valve body sealing washer on the inner circumference of valve body, is equipped with matched with butterfly plate rubber seal on the outer circumference of sparse tooth formula butterfly plate, the cross-section of butterfly plate rubber seal is the forked tail zigzag, follows correspondingly the outer circumference of sparse tooth formula butterfly plate seted up the mounting groove that can hold forked tail zigzag butterfly plate rubber seal, and the cross-section of mounting groove also is the forked tail zigzag; drainage holes are uniformly distributed and communicated at intervals at the bottom of the dovetail zigzag mounting groove, and pressure guide holes communicated with the drainage holes are correspondingly formed in the plate surface of the thinning-tooth butterfly plate.
Adopt above-mentioned structure's non-pressure plate to dredge tooth-like butterfly valve because forked tail zigzag butterfly plate rubber seal has certain elasticity, therefore accessible extrusion mode lay in the matched with mounting groove that the outer circumference of sparse tooth-like butterfly plate was seted up, again because forked tail zigzag mounting groove's tank bottom interval equipartition intercommunication has the drainage hole, dredge on the face of tooth-like butterfly plate corresponding seted up with the drainage hole is linked together lead the pressure hole, therefore fluid medium pressure is used on forked tail zigzag butterfly plate rubber seal through leading pressure hole and drainage hole, fluid medium pressure is big more, the sealed effect between forked tail zigzag butterfly plate rubber seal and the valve body sealing washer is better, can not have the seepage phenomenon, simultaneously the utility model discloses need not cooperate by the clamp plate, has reduced manufacturing cost.

Detailed Description
Referring to fig. 1-3, the utility model discloses a non-pressure plate sparse tooth type butterfly valve has valve body 1 and sparse tooth type butterfly plate 2, is equipped with valve shaft 3 on the valve body, and sparse tooth type butterfly plate 2 is adorned in valve body 1 through valve shaft 3, has valve body sealing washer 4 on the interior circumference of valve body 1, is equipped with matched with butterfly plate rubber seal 5 on the outer circumference of sparse tooth type butterfly plate 2, the cross-section of butterfly plate rubber seal 5 is the forked tail zigzag, correspondingly along the outer circumference of sparse tooth type butterfly plate 2 seted up the mounting groove 6 that can hold forked tail zigzag type butterfly plate rubber seal 5, the cross-section of mounting groove 6 is the forked tail zigzag too; drainage holes 7 are uniformly distributed and communicated at intervals at the bottom of the dovetail zigzag mounting groove 6, and pressure guide holes 8 communicated with the drainage holes 7 are correspondingly formed in the plate surface of the thinning-tooth butterfly plate 2.
