Description
Technical field
The utility model relates to heavy oil refining equipment field, is specifically related to heavy oil storage tank special valve.
Background technique
At present, due to the particularity of heavy oil, valve common on the market for during heavy oil feedstock tank or the waste heat of heavy oil can not be born, or due to furol viscosity too high, valve easily blocks, and after using one end time, switch gets up difficultly.
Model utility content
The purpose of this utility model is exactly at present, due to the particularity of heavy oil, valve common is on the market for during heavy oil feedstock tank or can not bear the waste heat of heavy oil, because furol viscosity is too high, valve easily blocks, use switch after the time of one end to get up hard deficiency, and heavy oil storage tank special valve is provided.
The utility model comprises valve body, A abutted flange, adjusting screw rod, tapered piston, rectangular tube and B abutted flange, valve body is respectively equipped with entrance, tapered channel, outlet and tapped hole, A abutted flange is respectively equipped with oil seal groove and one group of flange mounting hole, A abutted flange is fixedly mounted on and is arranged on valve body inlet end, and the inner ring of A abutted flange communicates with the entrance of valve body, adjusting screw rod is positioned at the tapped hole of valve body, tapered piston is arranged on adjusting screw rod and is positioned at body cavity one end, and tapered piston is positioned at the tapered channel of valve body, one end of rectangular tube communicates with the outlet of valve body, B abutted flange is respectively equipped with oil seal groove and one group of flange mounting hole, B abutted flange is fixedly mounted on the other end of rectangular tube, and the inner ring of B abutted flange communicates with the outlet of valve body.
It also has valve handle, and valve handle is fixedly mounted on adjusting screw rod and is positioned at one end outside valve body.
The utility model advantage is: adopt mechanical structural design, and install simple, resistance to heat is good, and the piston not also being afraid of switch after using one end time is corroded by heavy oil and clings.
