The one end at the mouth of a river is equipped with the filter screen, and the side of the water inlet is equipped with second recirculation hole, the water inlet it is another
Side is equipped with first recirculation hole, and the other side of the platen is equipped with the spring valve seat, and the other side of the spring valve seat is set
There is the spool, the bottom end of the spool is equipped with the gasket seal, and the other side of the spool is equipped with the valve rod, the valve
The bottom end of bar is equipped with the fastening nut, and the other side of the valve rod is equipped with the fixed frame.
Further, the filter screen is fixedly connected with the water inlet.
Further, the spring valve seat and the spool are closely coupled.
Further, the water inlet is through setting in the valve body.
Further, first recirculation hole, second recirculation hole and the water inlet are through setting.
Compared with prior art, the utility model has the beneficial effects that this kind prevents the ball valve of the stifled card of high temperature, structure compares
Simply, this kind of spring valve seat opens installation using stream, and valve seat and valve core sealed cover easily contact, when high temperature, not will lead to valve seat and
Spool because pressure it is excessive caused by be close together, therefore stuck phenomenon is not present for high temperature, and is equipped in water inlet
Filter screen can prevent biggish sundries from entering device and resulting in blockage.
