Description
Technical field
The utility model relates to a kind of valve, especially relates to a kind of material bin pump that is used for, the pneumatic rotary feeding valve arrangement improvement of occasions such as pipeline switching.
Background technique
At present, the valve great majority that are used on the strength transported substance feed bin pump are pneumatic bivalve plate gate valves, this gate valve adopts the straight reciprocating motion form, mainly by cylinder, valve body and be located at the connecting shaft of valve seat, valve, connection valve and the cylinder of its both sides, the power of cylinder drives the straight reciprocating motion of valve by connecting shaft, thereby realizes the switch motion of valve.For example, Chinese patent literature discloses a kind of fluidized pump Pneumatic butterfly valve (application number: 97242936.0), mainly by cylinder body with place the piston in the cylinder body to form, the two ends of cylinder body are provided with pneumatic head, be respectively equipped with air inlet/outlet on the cylinder body, be provided with 2 cavity volumes in the cylinder body, the piston that is placed in the cylinder body has 2, is connected on the same axle center.
The sealing friction pair of this kind motion mode is shorter working life, and sealability reduces the rate of fault height greatly after use a period of time.And, after long-time the use, in the valve body chamber, pile up dust easily, tightness is also not satisfactory.
Summary of the invention
The utility model mainly is to solve the existing in prior technology complex structure, and the valve pocket design is very unreasonable, piles up dust easily, and cracking pressure is big, the technical problem that valve plate is difficult to put in place etc.; Provide a kind of simple in structure, be difficult for piling up dust, cracking pressure is little, the pneumatic rotary feeding valve of valve plate accurate positioning.
The utility model has simultaneously solved the existing in prior technology poor sealing again, is easy to wearing and tearing, the technical problem that working life is short etc.; The movement locus that a kind of valve plate and seal ring friction pair are provided is a circular arc, good airproof performance, the pneumatic rotary feeding valve of long service life.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: pneumatic rotary feeding valve, comprise the cylinder of being located on the support, valve body and connect thereon valve seat, one side of valve seat endoporus is provided with seal ring, the seal ring formation sealing friction pair that matches with valve plate, it is characterized in that being hinged at described cylinder and fork one end, the other end of described fork is matched with fulcrum one end that is located on the valve seat, the other end of described fulcrum has connected running shaft, and described running shaft is provided with valve plate.Scheme of the present utility model changes the straight reciprocating motion of original valve plate into motion that movement locus is a circular arc, is convenient to its location like this, helps simultaneously reducing wear, and increases the service life, and improves tightness.
For running shaft is carried out two-way support, improve stability, as preferably, described is located on the supporting base, and described supporting base is located at body cavity.
As preferably, described valve body is provided with arc-shaped cavity.Adopt this structure can prevent effectively that dust from piling up in valve body, be convenient to regular maintenance.The arc-shaped cavity here can be made as different shapes such as sphere, hemisphere.
As preferably, described running shaft is provided with the single face valve plate, and running shaft links to each other by connecting body with valve plate, is provided with spring therebetween.Spring helps improving tightness.
As another kind of scheme, described running shaft is provided with two-sided valve plate, and running shaft links to each other by connecting body with each valve plate, is provided with spring therebetween.
In addition, as preferably, the medial axis of described running shaft is vertical mutually with the medial axis of valve plate, and the medial axis of running shaft is vertical mutually with the medial axis of fulcrum.
Therefore, the utlity model has reasonable in designly, simple in structure, adopt valve plate rotary seal form, be convenient to locate and reduce friction, current global mechanism is imported and exported in the two-way support of running shaft, and valve body is provided with the arc inner chamber, be difficult for piling up dust, good airproof performance, cracking pressure is low, characteristics such as long service life.
