Yet, because welding temperature is too high, and the heat-affected zone is larger, cause easily the distortion, lower hardness of refrigerating ball valve etc. after causing welding when adopting the argon arc welding welding.And because the weld assembly of valve core case and connecting tube and spool and the relatively poor problem of coaxality between valve core case and the valve body occurs easily when tight, so cause easily the failure welding rate after argon arc welding is welded higher.After refrigerating ball valve service time was long, fracture or spilehole etc. appearred in weld easily, can't keep in repair, thereby so that the sealing between valve body and the valve core case reduces, leakage problem occur.
Summary of the invention
The purpose of this utility model is the problems referred to above that exist for prior art, has proposed a kind of difficult leakage, refrigerating ball valve simple in structure.
The purpose of this utility model can realize by following technical proposal: a kind of refrigerating ball valve, comprise valve body, spool, valve core case and take over one and take over two, described valve inner is cavity, above-mentioned spool and valve core case all are positioned at valve body and valve core case is spacing at valve body with spool, described adapter one is positioned at an end of valve body and communicates with its inner chamber, described adapter two is positioned at the other end of valve body and communicates with its inner chamber, it is characterized in that, described valve core case is connected with valve body screw thread, an above-mentioned adapter part is positioned at valve body and takes over an end and is resisted against on the valve core case, and described adapter one and adapter two and valve body are all by being welded and fixed.
This refrigerating ball valve in valve core case is threaded connection by complete screw-in valve body after, will take over again one and stretch in the valve body and lean with valve core case, afterwards again by welding will take over one and valve body between fix.So just so that valve core case, valve body and take over the welding procedure that location between one need not to need to adopt in the conventional construction argon arc welding, and because valve core case is to be located in first in the valve body, just so that the coaxality between valve core case and the valve body is better, therefore can avoid in use the valve core case that causes because coaxality is poor and the leakage problem between the valve body.Also effectively avoided simultaneously because of the poor problem of the higher valve core case that causes of argon arc welding failure welding rate and the sealing between the valve body, so that valve core case, valve body and the connection of taking between are more firm.
In above-mentioned refrigerating ball valve, described adapter one is flared copper tube.
In above-mentioned refrigerating ball valve, has seal ring between described valve core case and the spool.Seal ring can increase the sealing between spool and the valve core case.
In above-mentioned refrigerating ball valve, the contacted end of described valve core case and spool has for the packing holder that seal ring is installed.
In above-mentioned refrigerating ball valve, described valve core case has the joint that can link to each other with the instrument in the valve body that valve core case is packed into the contacted the other end of spool.The instrument that valve core case is installed by joint with can easily valve core case be installed in the valve body after valve core case is connected.
In above-mentioned refrigerating ball valve, described joint is the attachment hole that is prism-shaped.
Compared with prior art, this refrigerating ball valve welds by taking over behind the screw-in valve core case in the insertion valve body and with valve body in valve body first again, reduced the relatively poor problem of coaxality between valve body and the valve core case, improved the sealing between valve body and the valve core case, effectively eliminated the leakage problem between valve core case and the valve body, more stable during use, Security is higher; Simultaneously this refrigerating ball valve has omitted the welding procedure of argon arc welding, so that valve core case, valve body and to take over connection between one more simple and have firmly reduced the reject ratio of welding, has higher use value.
