Abstract
The invention discloses a refrigerating ball valve and a manufacturing process thereof. The refrigerating ball valve mainly comprises a valve body and a valve seat arranged in the valve body, wherein a seal ball is arranged in the valve seat; a rotating rod is arranged on the seal ball; a cap is arranged on the upper part of the valve body; the rotating rod is arranged in the cap; two sides of the valve body are provided with joints; the joint on one side is screwed with a connection tube, pressed by a screw cap and welded and fixed by argon arc welding; the joint on the other side is connected with the connection tube; a necking is arranged at the connection position for connection; and an O-shaped seal ring, a gasket and a disc spring are arranged at the connection position between the necking and the joint. The manufacturing process comprises the following steps of: connecting an interface on one side of the valve body of the ball valve with the connection tube; arranging the gasket on the interface on the other side, and arranging the O-shaped seal ring and the disc spring on the gasket; and sleeving the connection tube on the interfaces, and shrinking the connection tube to a designed specification with a pipe-shrinkage machine, wherein a part of the connection tube on the interfaces of the valve body is shrunk and pressed on the interfaces to form the necking. The refrigerating ball valve is suitable to be used for refrigerating machines, refrigerating apparatuses and the like.
Description
Technical field
The present invention relates to a kind of refrigerating ball valve and preparation process thereof that is used for refrigerant pipe.
Background technique
The ducted ball valve of refrigeration system is a kind of fluid control member, and the application of ball valve more and more widely and requires also increasingly high.At present, China produces small-sized ball valve, and technology content is not high, and is main with manual poor efficiency ball valve.So, traditional refrigerating ball valve since its in process of production ball valve and connecting tube adopt the welding procedure of argon arc welding, first 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 objective of the invention is to defective, a kind of refrigerating ball valve easy to make and preparation process thereof are provided to above-mentioned refrigerating ball valve existence.
In order to achieve the above object, the present invention has mainly adopted following technological scheme to accomplish.The technological scheme of refrigerating ball valve of the present invention is: mainly be 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 provided with the O RunddichtringO between block and the valve body in block; 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, on one side joint be provided with internal thread, and be provided with externally threaded connecting tube and spin mutually; And use nut compressing, fixing with the argon arc welding.The joint of another side is connected with connecting tube, is provided with reducing in the joint and connects, and also is provided with the sealing of O type circle in reducing and joint joint, also is provided with pad and belleville spring, has increased flexible compensation, the sealing of the company's of assurance head.
Described preparation process of the present invention is: earlier one side interface on the valve body of ball valve is connected with connecting tube; The method that connects is on interface, to be provided with internal thread, and connecting tube is provided with outside thread, after connecting tube and interface spin; Compress with nut, fixing with the argon arc welding.On the interface of the another side of the valve body of ball valve; Pad is set, O RunddichtringO and belleville spring are set on pad; On interface, put connecting tube then; With machine for shrinking connecting tube is narrowed down to design specification again, the part of this connecting tube on the valve body interface just dwindled to be pressed on and formed reducing on the interface.
The present invention compared with prior art has following tangible advantage and progress.(1) technology is simple.The present invention adopts necking down process, and the Placement of connecting tube and valve body interface is used the machine for shrinking reducing, and it is firmly connected.Changed traditional argon arc welding welding, owing to the high shortcoming that burns out pad, seal ring of temperature.(2) quality assurance.Owing to adopt necking down process,, guaranteed the requirement of sealing so on interface, can increase pad, belleville spring and O RunddichtringO.(3) easy to maintenance.The present invention is owing to be the reducing sealing, so when needing repairing, can take connecting tube apart and keep in repair, traditional argon arc welding welding is in case there is spilehole just to be difficult to maintenance.
The present invention is applicable to uses such as refrigerator, refrigeration equipment.
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail.
Description of drawings
Accompanying drawing is an overall structure cut-away view of the present invention.
Embodiment
As shown in the figure, the present invention mainly is made up of valve body 2 and 10 of valve seats being located in the valve body 2, in valve seat 10, is provided with ball sealer 9; Ball sealer 9 is provided with swing arm 5, above valve body 2, is provided with block 3, and swing arm 5 is in block 3; Be provided with O RunddichtringO 4 between block 3 and the valve body 2, be provided with O RunddichtringO 8 between swing arm 5 and the valve body 2, in block 3; Also be provided with packing ring 6 and swing arm lining ring 7 between block 3 and the swing arm 5, the both sides of described valve body 2 are provided with joint 15,12, and joint 15 is provided with internal thread; Spin mutually with being provided with externally threaded connecting tube 1, and use nut compressing, fixing with the argon arc welding.Joint 12 is connected with connecting tube 13, is provided with reducing 14 in the joint and connects, and also is provided with O type circle sealing 11 in reducing 14 and joint 12 joints, also is provided with pad 17 and belleville spring 16, has increased flexible compensation, the sealing of the company's of assurance head.
Described preparation process of the present invention is: earlier one side interface 15 on the valve body 2 of ball valve is connected with connecting tube 1; The method that connects is on interface 15, to be provided with internal thread, and connecting tube 1 is provided with outside thread, after connecting tube 1 spins with interface 15; Compress with nut, fixing with the argon arc welding.On the interface 12 of the another side of the valve body 2 of ball valve; Pad 17 is set, O RunddichtringO 11 and belleville spring 16 are set on pad 17; On interface 12, put connecting tube 13 then; With machine for shrinking connecting tube 13 is narrowed down to design specification again, this connecting tube 13 just dwindles to be pressed in the part on the valve body interface 12 and forms reducing 14 on the interface 12.
The present invention is applicable to uses such as central air-conditioner, heating, water treatment, industrial processes industry, refrigerator, refrigeration equipment.
