Description
Technical field
The utility model relates to a kind of ducted refrigerating ball valve of refrigeration system that is used for.
Background technique
The ducted ball valve of refrigeration system is a kind of fluid control member, and the application of valve more and more widely and requires also more and more higher.At present, China produces small-sized valve, and technology content is not high, and based on manual poor efficiency valve.So, traditional refrigeration valve is because its welding procedure of valve and connecting tube employing argon arc welding in process of production, earlier ball valve interface and connecting tube are compressed with screw thread, again with the argon arc welding, in welding process, because temperature is too high, the pad of being located in the valve body melts easily, aging, as spilehole appears, also can't keep in repair.
Summary of the invention
The purpose of this utility model is to provide a kind of quality assurance at the existing shortcoming of above-mentioned refrigerating ball valve, New Refrigerating ball valve easy to maintenance.
In order to achieve the above object, the utility model is mainly finished by the following technical solutions.The utility model mainly is made up of valve body and the valve seat be located in the valve body, in valve seat, be provided with ball sealer, ball sealer is provided with swing arm, above valve body, be provided with block, swing arm is in block, be provided with the O RunddichtringO between block and the valve body, be provided with the O RunddichtringO between swing arm and the valve body, in block, also be provided with packing ring and swing arm lining ring between block and the swing arm, the both sides of described valve body are provided with joint, joint on one side is provided with internal thread, spins mutually with being provided with externally threaded connecting tube, and uses nut compressing, connecting tube is provided with the liquid-filling valve valve body, and the liquid-filling valve valve body is provided with valve inside.The joint of the another side of valve body is connected with connecting tube, and described joint is provided with locking nut, is provided with reducing in the joint and connects, and also is provided with packing ring and the sealing of O type circle in reducing and joint joint.
The utility model compared with prior art has following tangible advantage and progress.(1) technology is simple.Threaded adjusting technology is adopted in connecting tube of the present utility model joint, and adopts seal ring, pad to do sealing and flexible compensation, thereby guarantees the sealing and the handle rotation torque uniformity of valve body.(2) the valve body assembly technology adopts valve body and connecting tube to weld earlier and afterwards assembles necking down process again, has avoided the Sealing distortion that causes because of weld heating.(3) easy to maintenance.Traditional weld-end fittings can't keep in repair, and the interface that the utility model adopts reducing to connect, convenient disassembly is convenient to maintenance.
The utility model is applicable to uses such as refrigerator, refrigeration equipment.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
