Description
Technical field
The utility model relates to the butterfly plate controlling device of a kind of butterfly valve, particularly a kind of butterfly valve.
Background technique
The butterfly valve that vertical use is arranged in the butterfly valve.Vertical butterfly valve has the valve body of cylindrical cavity, body cavity has the valve seat along circumference, be embedded with valve seals on the valve seat, axial vertical valve shaft with valve body is arranged on the valve body, vertical butterfly valve in use, valve shaft is vertical with horizontal plane, stretch out outside the valve body by the valve shaft hole of valve body upside the upper end of valve shaft, the upper end of valve shaft can be connected with drive unit, the lower end of valve shaft is on the valve shaft seat of valve body downside, valve shaft is connected with butterfly plate a section of body cavity, and the butterfly plate seal ring that matches with valve seals is arranged on the butterfly plate.The valve shaft that is connected with butterfly plate is to act on the valve shaft seat of valve body downside, because it is bigger to be connected with the valve shaft weight of butterfly plate, vertical butterfly valve is after use after a while, the valve shaft that is connected with butterfly plate has certain wearing and tearing to the valve shaft seat, valve shaft can drive the downward sedimentation of butterfly plate, the downward sedimentation of butterfly plate, make butterfly plate seal ring and valve seals lose the relation that matches, for the butterfly plate that butterfly plate seal ring and valve seals is lost the matching relationship butterfly valve is regulated, in the prior art, below the valve shaft seat, interior threaded hole is arranged, be rotary with hexagon cap screw in the interior threaded hole, the hexagon nut of hexagon cap screw is in the valve body outside, after the valve shaft that is connected with butterfly plate makes butterfly plate seal ring and valve seals lose matching relationship because of sedimentation downwards, can be outside valve body the sideway swivel hexagon cap screw, the valve shaft that the is connected with butterfly plate jack-up that makes progress, make butterfly plate seal ring and valve seals recover matching relationship, in order to prevent that the stressed back counterrotating of hexagon cap screw from causing valve shaft to descend, outside hexagon cap screw, be covered with outer cover with the hexagon ring that matches with the screw hexagonal nuts, the screw hexagonal nuts is in the outer cover hexagon ring, outer cover with hexagon ring is connected in the valve shaft seat below in the valve body outside with the screw location, the constraint hexagon cap screw can not counterrotating, keeps the position behind butterfly plate seal ring and the valve seals recovery matching relationship.This have the butterfly valve of butterfly plate controlling device when regulating the matching relationship of butterfly plate seal ring and valve seals, because hexagon nut is subjected to want the constraint of outer cover hexagon ring, the butterfly valve of controlling device is not continuous in the process of the matching relationship of regulating butterfly plate seal ring and valve seals, but want the adjusting at the interval of 60 degree angles at interval at every turn, because this interval is arranged, the matching relationship of butterfly plate seal ring and valve seals can not meticulously be regulated, and the butterfly plate seal ring after feasible recovery the and the matching relationship of valve seals are not very strict.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, and proposing a kind of butterfly plate seal ring and valve seals at butterfly valve can meticulous adjusting butterfly plate seal ring after sinking to losing matching relationship because of valve shaft and the butterfly valve with butterfly plate controlling device of valve seals matching relationship.
The utility model is realized with the following method.
Butterfly valve with butterfly plate controlling device, the valve body that cylindrical cavity is arranged, body cavity has the valve seat along circumference, be embedded with valve seals on the valve seat, axial vertical valve shaft with valve body is arranged on the valve body, stretch out outside the valve body by the valve shaft hole of valve body upside the upper end of valve shaft, the lower end of valve shaft is on the valve shaft seat of valve body downside, valve shaft is connected with butterfly plate a section of body cavity, the butterfly plate seal ring that matches with valve seals is arranged on the butterfly plate, it is characterized in that: the bottom of valve shaft is the less multidiameter shaft of lower end external diameter, the valve shaft seat is the short pipe that links to each other with the valve body downside, the endoporus of short pipe bottom is the bigger shoulder hole of bottom diameter, there is adpting flange the lower end of short pipe, be connected with the flange gland on the adpting flange, be evenly equipped with relative attachment hole respectively between flange gland and the adpting flange, attachment hole on the adpting flange has internal thread, clamping bolt is arranged between the attachment hole, the flange gland has the pressure ring that raises up, the last collar extension of pressure ring has inside annular edge edge, the lower end of valve shaft is in the endoporus of pressure ring, the internal diameter of pressure ring matches with the external diameter of valve shaft lower end, between the ladder end face of the top and valve shaft multidiameter shaft of pressure ring the end face bearing is arranged, between the adjacent attachment hole location interior threaded hole is arranged on the flange gland, be rotary with holding down bolt in the interior threaded hole of location, the shaft end pressure plate that the useful screw in the lower end surface of valve shaft links to each other, the endoporus of flange gland has internal thread, is rotary with the lower end capping on the internal thread.
During use, when the valve shaft that is connected with butterfly plate produces certain wearing and tearing to the valve shaft seat, valve shaft drives the downward sedimentation of butterfly plate, the butterfly plate seal ring is with after valve seals loses the relation that matches, in order to recover the matching relationship of butterfly plate seal ring and valve seals, can screw clamping bolt, make the pressure ring jack-up valve shaft that makes progress, the drive butterfly plate moves upward, regulate butterfly plate seal ring and valve seals to the position of matching, the rotation positioning bolt is tight against on the lower end surface of adpting flange the upper end of holding down bolt then, the position after keeping regulating.
The utility model is with the rotation clamping bolt jack-up valve shaft that makes progress, regulate the relation that the butterfly plate seal ring matches with valve seals, be tight against on the lower end surface of adpting flange with the rotation positioning bolt, keep the position after butterfly plate seal ring and valve seals recover matching relationship.Regulate cooperation with clamping bolt, use the holding down bolt holding position, the matching relationship of meticulous adjusting butterfly plate seal ring of energy and valve seals, the butterfly plate seal ring after feasible recovery the and the matching relationship of valve seals are very strict.
