The utility model is for solving above technical problem, adopt following technological scheme: a kind of hand lever relief valve, mainly comprise valve seat, spool, valve gap, adjustable cap, spring, handle, valve gap one end is fixedly connected with valve seat by clip, the joint of valve gap and valve seat is also provided with O type circle, the other end is threaded with adjustable cap, it is characterized in that: the head of spool is positioned at valve seat, and on head, be also provided with seal ring, the afterbody of spool is through valve gap and adjustable cap, the joint of spool and valve gap is provided with the shaft sealing sealing and the bearing housing playing the role of positioning successively, the joint of spool and fixing bolt is provided with the clip bearing that plays the role of positioning, spring housing is at the middle part of spool, and one head is fixed on the flange place of spool, and other end is positioned on spring seat, and fixes by fixing bolt, handlebar head end connecting handle, tail end connects the tail end of spool by pin.
As further setting of the present utility model, described handlebar is eccentric fulcrum design, its one end is small cylindrical, be connected with handle, the other end is large cylinder, in cylindrical body central vertical direction, be provided with square groove, and depart from cylindrical center line and be provided with through hole, this through hole connects the tail end of spool by pin.
As further setting of the present utility model, between described handlebar and pressure regulating cover, be also provided with abrasionproof effect pad.
As further setting of the present utility model, described adjustable cap and valve gap threaded connection place are also provided with the locking nut of its locking effect.
The utility model adopts above technological scheme, compared with prior art has following technique effect:
1. the bias adopting due to handlebar of the present utility model connects fulcrum design, in the time of the state of emergency, when handle with sleeve, pin eccentric on handle can be with movable valve plug to move up, start fast spool, the spool of sealing is opened rapidly, and the dielectric fluid of pipeline is known from experience release rapidly, again handle with sleeve valve rod, spool resets under the elastic force effect of spring.
2. the utility model has increased the locking nut of locking gear, prevents adjustable cap) loosening, and can rotate adjustable cap and adjust relative position between adjustable cap and valve gap and can adjust the size of sealing load, realize sealing load pre set force.
