Abstract
A flanged valve with a copper pipe comprises a valve body and a flared connecting pipe, wherein the flared connecting pipe is connected to the valve body and utilizes a tapered copper pipe fitting with a throat structure, and the minor-diameter end of the flared pipe is welded with the valve body. The flanged valve with a copper pipe resolves problems that the existing flanged valves are poor in welding sealing property, inconvenient in welding, low in flanged valve cleanliness and rough in products, prevents solder skips or melting on welding portions, is uniform in color of the surface of the valve body without burn or oxidation, and has the advantages of convenient welding, saving welding materials, increasing cleanliness of the flanged valve and the system thereof.
Description
Technical field the utility model relates to a kind of flange valve with copper pipe, belongs to refrigeration plant auxiliary products technical field.
The flange valve that background technique is used on refrigeration system semi-closed compressor group intake and exhaust pipeline at present, the enlarging connecting tube that it is connected with semi-closed compressor is to be welded by steel pipe, and the flange valve of this material and structure exists the defective that welded seal is poor, welding is inconvenient, the flange valve turbidity test are low and the finished product welding is coarse for refrigeration system.
Summary of the invention the utility model provides a kind of flange valve of band copper pipe of novelty, adopts copper tubing and bronze integral solder technology, realizes the purpose that improves refrigeration system turbidity test, good welds performance and save welding consumables.
The technical solution adopted in the utility model is:
A kind of flange valve with copper pipe comprises: valve body, enlarging connecting tube, on valve body, be connected with the enlarging connecting tube, and the enlarging connecting tube is throat structure for becoming the copper tubing of diameter, and the smaller diameter end and the valve body of enlarging connecting tube are welded to connect.
The utility model beneficial effect is:
Owing to adopted the flange valve of band copper pipe of the present utility model, solved the problem that existing flange valve welded seal is poor, welding is inconvenient, the flange valve turbidity test are low and finished product is coarse, the welding part does not have the weldering of leakage, lack weldering and fusing, the valve body surface color is even, nothing is burnt, snperoxiaized phenomenon, has the characteristics of convenient welding, saving welding consumables, raising flange valve and system's turbidity test.

Embodiment
As shown in Figure 1 and Figure 2.
A kind of flange valve with copper pipe, comprise: valve body 1, enlarging connecting tube 2, on valve body 1, be connected with enlarging connecting tube 2, enlarging connecting tube 2 is for becoming the copper tubing of diameter, be throat structure, the smaller diameter end of enlarging connecting tube 2 and the bronze welding wire of valve body 1 usefulness carry out being welded to connect in the whole stove.
Flange valve valve body 1 and enlarging connecting tube 2 and employing furnace brazing, the welding part does not have the weldering of leakage, lacks bad phenomenon such as weldering and fusing, flange valve valve body 1 surface color is even, there are not bad phenomenon such as burn, peroxidating, through air tight test, weld and sealing part must not have leakage phenomenon, and overlay coating is Sn.
After qualified the opening of enlarging connecting tube 2 is closed dustproofly with special-purpose plug, just flange valve can be applied to then on the refrigeration system semi-closed compressor group, during use special-purpose dust plug taken off and get final product.
