The utility model aims to provide a stop valve capable of realizing fluorine filling in a valve rod so as to solve the problems in the background technology.
The technical scheme adopted by the utility model is as follows:
the utility model provides a can realize filling stop valve of fluorine in valve rod, includes the valve body, be equipped with the valve rod in the valve body inner chamber, be equipped with the valve core in the valve rod inner chamber, the valve rod left end cover is equipped with the stopping circle, the valve rod outside cover is equipped with O type circle, the valve body right-hand member is equipped with the copper pipe, the valve body upper end is equipped with the sealing cap to it is fixed through the cross nut, the valve body left end has connect the upper cover nut soon.
Preferably, the copper pipe extends into the inner cavity of the valve body.
Preferably, the valve rod extends into the left side of the inner cavity of the valve body.
Preferably, the copper pipe is connected with the valve body by brazing.
Preferably, the valve body is provided with a fluorine filling port communicated with the inner cavity, so that the fluorine filling is convenient.
In summary, due to the adoption of the technical scheme, the beneficial effects of the utility model are as follows:
according to the utility model, on one hand, a fluorine filling port which is independently arranged in the prior art is removed, a new fluorine filling port is arranged in the valve rod, a small Kong Chong injection is required to be drilled at the side part of the valve rod, the structure is simple and easy to realize, and the requirements on the processing precision are not high, so that the requirements on fluorine filling and sealing performance can be realized; on the other hand, the structure of the stop valve is optimized, the material cost and the processing cost can be reduced, and meanwhile, the product performance can be ensured. Energy saving and material saving, excellent performance, reasonable structural design and strong practicability.
