Abstract
The utility model provides a pneumatic rotating disc valve which comprises a valve seat. The valve seat is provided with two parallel valve plates, a pneumatic actuator is fixed on the valve seat by abracket, a connecting rod is fixed at one end of the pneumatic actuator, one end of a driving arm is fixed at the connecting rod, and the other end of the driving arm is fixed at a hollow transverseshaft. The hollow transverse shaft is arranged in sunken holes of the two parallel valve plates, and a spring is arranged in a cavity of the transverse shaft. A pneumatic device drives the two valve plates to match the spring between the two valve plates, so as to lead the valve with two gate plates to cling to a valve body. Along with the rotating of the valve plates, mutual grinding is incurredbetween the sealing surfaces of the valve body and the valve plates, which not only can polish the sealing surfaces, but also can remove accumulated substances on the valve seat, thereby enhancing thesealing property of the valve for long-time use and prolonging the service life of the valve.
Description
Technical field
The utility model relates to a kind of plate valve, relates to a kind of pneumatic rotational circle moushroom valve specifically.
Background technique
In the middle of industries such as power station, mine, papermaking and chemical industry, people often need materials such as ash-slag delivery, water, solution or steam.In order effectively to control the flow of carrying, on the pipeline of carrying, one or more keyings or flow control valve are installed usually.Because in this class valve transportation of substances particularity of work, hard lime-ash can make valve part wear and tear easily, acidity or alkaline solution then can make the valve corrosion, water or solution also can make the easy corrosion of pipeline, thereby make the sealability of parts descend, reduced working life, maintain and replace rate height, the also corresponding increase of equipment loss rate.
Summary of the invention
The purpose of this utility model is to disclose a kind of pneumatic rotational circle moushroom valve, and the Pneumatic actuator that is fixed in valve seat drives the bivalve plate, cooperates with the spring between the bivalve plate, makes the double-flashboard valve be close to valve body.Defectives such as along with the rotation of valve plate, the sealing surfaces of valve body and valve plate grinds mutually, and sealing surface is polished, and can also root out the valve seat deposit, has overcome valve and has used sealing effect to descend for a long time, and service time is short.
The technological scheme that the utility model adopted is that described pneumatic rotational circle moushroom valve comprises:
Be provided with the valve seat of parallel double valve plate, pneumatic actuator is fixed in valve seat by support, and an end is fixed with a connecting rod.Driving arm one end is fixed in connecting rod, and the other end is fixed in the hollow transverse axis.The hollow transverse axis is arranged in the counterbore of parallel double valve plate, and spring is arranged in the cavity of transverse axis.
A plane is formed by three bolts in the joint of described support and valve seat.
The axis of pitch of described valve seat departs from the valve body central transverse axis.
Pneumatic actuator drivening rod and driving arm rotated for 1/4 week and drive the motion of bivalve plate, the whole sealing surfaces of two parallel valve plates is close to the sealing surface of valve seat under the effect of spring, but valve plate axial motion under the effect of the spring force of spring, can mend thermal expansion, deflation and the wearing and tearing of tasting valve member, prevent that tiny granule medium from entering sealing surface, guarantee tight closing, equalizing main pressure.
The friction of valve driving arm active force and sealing surface makes valve plate paste sealing surfaces to rotate automatically around self axis, thereby reaches the polishing sealing surface and root out the purpose of valve seat deposit.
The beneficial effects of the utility model:
Pneumatic rotational circle moushroom valve described in the utility model drives the bivalve plate by Pneumatic actuator, cooperates with the spring between the bivalve plate, makes the double-flashboard valve be close to valve body.Along with the rotation of valve plate, the sealing surfaces of valve body and valve plate grinds mutually, and sealing surface is polished, and can also root out the valve seat deposit, has strengthened the long-term sealability of using of valve, has increased working life.
