Description
Technical field
The utility model relates to the valve arrangement technical field, specifically a kind of streamlined eccentric intercept sphere valve with the cam sealed member.
Background technique
Valve is the controlling component in the fluid delivery system, has cut-off, adjusting, water conservancy diversion, prevents the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief.The valve that is used for liquid control system, from the simplest stop valve to very complicated robot control system(RCS) used various valves, its kind and specification are quite various.Conventional valves spool and valve base sealing increase constantly by eccentric spool turning radius that the extruding valve seat realizes, in the valve closing process, the wearing and tearing of spool and valve seat increasing in the working life of having reduced spool and valve seat, has increased the user cost of valve.Simultaneously simple eccentric force sealing effect is not good enough.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of streamlined eccentric intercept sphere valve with the cam sealed member is provided.
The technical solution of the utility model realizes in the following manner, should be with the streamlined eccentric intercept sphere valve of cam sealed member, its structure comprises valve rod, valve body, spool and valve seat, stretch on the valve rod of valve inner and be connected with cam, cam is arranged in the cam letter, cam letter oral area has been threaded connection connecting sleeve, slide in the connecting sleeve and be provided with the cross piston, the end of cross piston in the cam letter is provided with pulley, be provided with Returnning spring between cross piston and the connecting sleeve, Returnning spring presses the cross piston that pulley is matched with cam by the top, and the cross piston the other end connects the spool arm of force, the spool arm of force connects spool, and spool one side is provided with valve seat.
Be provided with stop screw on the cam letter wall.
Be provided with jackscrew between connecting sleeve and the cam letter oral area.
Be provided with the O RunddichtringO in the connecting sleeve and between the cross piston.
Be provided with the driving mechanism that two covers are made of cam, cam letter, pulley, cross piston, connecting sleeve, Returnning spring on the valve rod in the valve body, this two sets of transmission mechanism connects respectively the spool arm of force.
The beneficial effect that the utility model compared with prior art produces is:
Should be with structural feature of the streamlined eccentric intercept sphere valve of cam sealed member: spool be opened, in the closing process, the frictional force of moment, spool and valve seat that valve rod drives spool is very little, reached reduce cost, improve working life, the purpose of enhancing sealing effect.
When valve closing, valve rod drives valve core movement under the effect of actuator, when spool contact with valve seat cooperate after, cam promotes the cross piston and promotes spool and valve seat closely cooperates, impel spool and valve seat to produce seal pressure, acting in conjunction realizes the purpose of valve excellent sealing.The cross piston drives valve core movement under the effect of cam, realize between spool and the valve seat that less friction cooperates, and has reduced the wearing and tearing of spool valve seat, has greatly improved the working life of spool valve seat.Therefore, the camflex valve that driving moment is relatively traditional reduces greatly, has reached purpose energy-conservation and the reduction cost.The cross piston promotes spool and cooperates the generation seal pressure with valve seat under the effect of cam, it and eccentric force acting in conjunction make the valve seal effect more remarkable.
Should be reasonable, simple in structure, safe and reliable, easy to use with the streamlined eccentric intercept sphere valve design of cam sealed member, be easy to safeguard, have good value for applications.
