Abstract
The utility model discloses a rotational circle poppet valve sealing device. Including valve body, valve plate and cylinder, the valve port has in the valve body, and the valve port passes through the valve plate is sealed, and the cylinder is through even axle and crank one end swing joint, the crank other end and rotation axis swing joint, the rotation axis with valve plate fixed connection, there is annular separation blade in valve port department through dead lever fixed connection, and annular separation blade external conjugate diameter is greater than a plurality of through -holes have been seted up to the diameter of valve port on the annular separation blade, every equal sliding connection has cylindrical connecting rod in the through -hole, and the connecting rod is close to the one end tip of valve port is provided with a plurality of brush hairs, and other end tip is provided with the connection piece, the connection piece with be provided with the spring between the annular separation blade outer wall. The utility model discloses a fluid is to the thrust of cylindrical connecting rod for the setting is cleaned at the automatic impurity to valve port edge of the brush hair of its tip, thereby the protection valve plate and is guaranteed that the valve plate can be closed and is put in place by the impurity wearing and tearing.
Description
Technical field
The utility model relates to a kind of rotating disk valve sealing means.
Background technique
Plate valve is widely used in the fields such as chemical industry, metallurgy, hydraulic engineering, existing plate valve, when gate valve is opened, flashboard leaves valve port, flowing medium flows out, but when containing more impurity in flowing medium, impurity easily cannot be discharged in time in the attachment of valve port edge, when valve plate close port, valve plate can first contact with this part impurity, and this part impurity can, to wearing and tearing valve plate, get off to cause valve plate normally cannot seal up valve port for a long time on the one hand, flashboard can be made not close on the other hand to put in place, reduce the sealing of plate valve.
Summary of the invention
The utility model is for deficiency of the prior art; provide a kind of rotating disk valve sealing means; it is by the thrust of fluid to cylindrical connecting rod; the bristle being arranged on its end is cleaned the impurity of valve port edge automatically; thus protection valve plate is not worn and torn by impurity, and ensure that valve plate can be closed and put in place.
For solving the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of rotating disk valve sealing means, comprise valve body, valve plate and cylinder, in described valve body, there is valve port, described valve port is sealed by described valve plate, described cylinder is flexibly connected with crank one end by connecting shaft, the described crank the other end is flexibly connected with running shaft, described running shaft is fixedly connected with described valve plate, described valve port place is fixedly connected with annular catch by fixing rod, described annular catch outer diameter is greater than the diameter of described valve port, described annular catch offers some through holes, cylindrical connecting rod is all slidably connected in each described through hole, described cylindrical connecting rod is provided with some bristles near the end, one end of described valve port, the other end end is provided with connecting sheet, spring is provided with between described connecting sheet and described annular catch outer wall.
During use, valve plate enters between annular catch and valve port by the gap location between two fixing rods, and seal up valve port, and annular catch can stop most impurity, but still have partial impurities and be attached to valve port edge, this part impurity is by the bristle cleaning on cylindrical connecting rod, specifically, by the impact of fluid to connecting sheet, cylindrical connecting rod is moved toward valve port side, when the bristle of cylindrical connecting rod end is near valve port, can first contact with the impurity at this place, by contacting the impact force produced with impurity, the impurity being attached to valve port edge is made to leave valve interior wall, namely valve port edge, thus play the effect of cleaning impurity, simultaneously, by the effect of spring, cylindrical connecting rod can back be retracted, again by the impact of fluid, make cylindrical connecting rod Infinite Cyclic aforesaid operations.
In technique scheme, preferably, described valve body is provided with support, described cylinder is arranged on the bracket.
In technique scheme, preferably, the end, one end that described cylindrical connecting rod arranges bristle is also rotatably connected to ball, and described ball outer wall is also provided with bristle.By arranging the ball be rotationally connected, make the impurity at valve port edge cleaner by what clean.
The beneficial effects of the utility model are: the utility model is by the thrust of fluid to cylindrical connecting rod; the bristle being arranged on its end is cleaned the impurity of valve port edge automatically; thus protection valve plate is not worn and torn by impurity, and ensure that valve plate can be closed and put in place.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram.
Fig. 2 is the schematic cross-section of the utility model valve port and annular catch.
Fig. 3 is the cylindrical connecting rod schematic diagram of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail: see Fig. 1-Fig. 3, a kind of rotating disk valve sealing means, comprise valve body 1, valve plate and cylinder 2, in described valve body 1, there is valve port 3, described valve port 3 is sealed by described valve plate, described cylinder 2 is flexibly connected with crank 22 one end by connecting shaft 21, described crank 22 the other end is flexibly connected with running shaft, described running shaft is fixedly connected with described valve plate, valve plate opens close port by running shaft, identical with conventional plate valve.
Described valve port 3 place is fixedly connected with annular catch 5 by fixing rod 4, namely annular catch 5 is arranged on valve body 1 inwall, and be positioned at valve port 3 edge, annular catch 5 shelters from the valve interior wall being positioned at valve port 3 edge, described annular catch 5 outer diameter is greater than the diameter of described valve port 3, described annular catch 5 offers some through holes 51, cylindrical connecting rod 6 is all slidably connected in each described through hole 51, described cylindrical connecting rod 6 is provided with some bristles near the end, one end of described valve port 3, the other end end is provided with connecting sheet 61, spring 62 is provided with between described connecting sheet 61 and described annular catch 6 outer wall.
Described valve body 1 is provided with support 11, and described cylinder 2 is arranged on described support 11.
The end, one end that described cylindrical connecting rod 6 arranges bristle is also rotatably connected to ball 63, and described ball 63 outer wall is also provided with bristle.By arranging the ball be rotationally connected, make the impurity at valve port edge cleaner by what clean.
During use, valve plate enters between annular catch and valve port by the gap location between two fixing rods, and seal up valve port, and annular catch can stop most impurity, but still have partial impurities and be attached to valve port edge, this part impurity is by the bristle cleaning on cylindrical connecting rod, specifically, by the impact of fluid to connecting sheet, cylindrical connecting rod is moved toward valve port side, when the bristle of cylindrical connecting rod end is near valve port, can first contact with the impurity at this place, by contacting the impact force produced with impurity, the impurity being attached to valve port edge is made to leave valve interior wall, namely valve port edge, thus play the effect of cleaning impurity, simultaneously, by the effect of spring, cylindrical connecting rod can back be retracted, again by the impact of fluid, make cylindrical connecting rod Infinite Cyclic aforesaid operations.
