angle valves   float valves   wall mount stop valve 6. When the solder in a viscous state, with brushes to clean and remove excess solder. Solder cooling after a valve in the Qiantiao around the port.

Silver brazing

If the different soldering materials, the brazing strength of the connection does not seem to be very good strength depends on the size of the pipe and valve shell casing between the normal and large-scale maintenance of cleanliness. Silver brazing of the valve casing of the internal diameter of the mechanical tolerances and surface smoothness require very precise in order to ensure adequate adhesion.

Note: in the clean-up and removal process, should be careful to observe the cleaning medium residues. In dirty or do not have the right to carry out cleansing of the surface, brazing, welding satisfactory results will be very difficult, because the silver brazing alloys will not flow or bond in the oxide, while the oil patches on the surface and exposed, Easily oxidized and led to the exclusion of debris and the gap flux.

Connecting thread

Hard residue, dirt or any external material accumulated in the pipeline may hinder the efficiency of valves and severe damage to key parts of the valve. Must be on the air or steam pipes to conduct a thorough internal cleansing.

When the tapping of pipelines to carry out, determined to pipe thread size and length of the pipeline will be filled to avoid valve seat and valve.

Thread the end of a thorough cleaning to remove any harmful steel or iron sediments. If you want a more solid when welding, it is necessary to use Teflon tape or channels adhesive. In the pipe thread on the pipeline can only use a small amount of adhesive, but in the thread on the valve can not use the pipeline adhesive. Do not let any adhesive into the pipe valve in the body so as to avoid damage to the valves and valve seat.

Pre-installed, to cut off the flow through the valve so that the normal work of the valve. To complete the installation before the closure of the valve. Wrench sets will be in the pipeline near the hexagonal bolt head to avoid possible deformation. After the installation of valves, it is necessary to support the pipeline to live: down the pipeline will have a valve failure caused by the deformation.

Flange connection

In order to ensure that the right to carry out the installation of valve-lan connection, the need to follow the following steps. First of all, carefully cleaning junction, and then, the base in the Department of loosely fitted with two or three bolts. Next, carefully insert the gasket junction. Contribute to the pads on the bottom of the bolts to locate and maintain appropriate. And then insert the bolt used to cross tightened up the way, do not tightened up around the use of the way, help to eliminate this over-concentration of pressure). In normal use for some time, to check whether or not to check all the bolts tightened up and tightened .Fore more information ,please visit http://www.bossgoo.com/
