Blowoff valve, the stop valve includes valve gap, and the valve gap upper end is provided with T-bolt, handle, institute are provided with outside the T-bolt
State valve gap lateral ends and be provided with mark, straight pin is provided with before and after the other end, the bottom of the straight pin is connected with valve body, the T
Type bolt is extended to inside valve gap, and O-ring is provided with inside the valve gap, and the upper and lower ends of the O-ring are provided with sealing member, and position
Valve rod is provided with the bottom of the sealing member of lower end, the lower end of the valve rod is provided with spherical valve core, the balanced valve, the valve of blowoff valve
Lid and its internal structure are identical with the structure of stop valve, and the balanced valve, blowoff valve all set demountable handle.
Preferably, the front of the valve body is provided with joint, and the joint is provided with pad.
Preferably, the balanced valve is rolled backward tiltedly with the body top set by blowoff valve.
Compared with prior art, the beneficial effects of the utility model are：The utility model simple structure, cost is relatively low, leads to
Arrange after rationally, realize being formed in a valve body four controllable paths of difference and a balance channel or four it is controllable can
The target of path and a direct path is adjusted, by the optimization design to valve rod leak-proof structure, makes spherical valve core streamlined, adjusted
During section operation, by the distance for changing spherical valve core and valve gap, it is possible to change the flow of fluid, change by means of its throttling action
The pressure of fluid.
