The start and stop of powder carry processed and conveying capacity.But the effect due to powder body and other foreign bodies, valve is easily stuck by bulky grain thing, often
Failsafe valve can be caused it is therefore desirable to provide a kind of stability higher powder inlet valve, to adapt to the requirement of correlation technique.
Utility model content
According to problems of the prior art, this utility model provides a kind of powder body inlet valve, this charging valve arrangement
Simply, dismounting is easy to maintenance, and stability is higher.
This utility model employs the following technical solutions:
A kind of powder body inlet valve, including valve body, valve seat, valve element, linkage and cylinder, described cylinder is arranged on valve body one
Side, the piston rod of cylinder connects valve element by linkage, and described valve seat is arranged on the discharge outlet of valve body, and close with valve element
Envelope cooperation.
Preferably, described linkage includes connecting rod one and connecting rod two, one end of described connecting rod one and the piston rod of cylinder
It is fixedly connected, the other end is hinged with one end of connecting rod two, connecting rod two other end is hinged with valve element.
Preferably, the longitudinal cross-section of described valve element is small top and big bottom.
It is further preferred that described valve element is bell valve element, described valve seat is closed with valve element matching form.
It is further preferred that being provided with sealing member between described valve seat and valve element.
It is further preferred that described sealing member is close to seat bottom portion setting, and sealing member is trapezoidal with the contact surface of valve element
Or arc.
Preferably, described sealing member is elastomeric material.
Preferably, the direction of motion of described valve element is provided with open guide plate.
Preferably, described connecting rod one is connected with the piston rod thread of cylinder.
Preferably, described cylinder and valve body link position are provided with cylinder mounting seat.
The beneficial effects of the utility model are:
1) this utility model connects the piston rod of cylinder and valve element so that valve is not easily blocked by linkage, stable
Property is higher, and substantially increases the service life of valve.
2) this utility model adopts bell valve element, and the valve seat closing with valve element matching form, improves valve to a greater extent
Matching degree between seat and valve element, can preferably block discharging opening, effectively prevented the problem of material leakage, brought to enterprise
Huge economic benefit.
3) setting of sealing member, further increases the sealing property of valve；Sealing member is designed as with the contact surface of valve element
Trapezoidal or arc, improves itself matching degree and valve element between, better tightness to a greater extent.
