The type of civil valve.

Civil valves of domestic valve manufacturers can be divided into civil gate valves, globe valves, ball valves, right angle valves (triangular valves), etc. according to their structure. In the connection between pipelines and water meters, gate valves are commonly used, while ball valves are the connections between pipelines. Since ball valves are easier to start than gate valves, ball valves are mostly used for connections between pipelines and water meters, while right-angle valves are generally sanitary ware. Connection of heating pipe hoses and pipes. Civil valves are generally made of iron or copper. Because copper alloys have good mechanical properties, corrosion resistance and corrosion resistance, the current production and sales of through solenoid valves far exceed iron valves.

Civil valve purchase

Users can choose different types of civilian valves according to their needs. Because the valve controls the pipeline medium, if a poor quality valve is selected, it is easy to cause leakage of other media such as water, causing leakage in the house, and causing property losses. Therefore, it is very important to choose a good quality water pump solenoid valve. Pay special attention to the following points:

When buying a valve, check that the valve surface should be free of blisters; the electroplating surface should be bright and uniform, and attention should be paid to whether there are peeling, cracking, scorching, bottoming, peeling, dark spots, and obvious pitting defects; the spraying surface should be fine, smooth and uniform , There must be no defects such as sagging and bottoming. The above shortcomings will directly affect the service life of the valve.

The pipe thread of the valve is connected with the pipeline. When purchasing, check whether there are obvious defects such as thread surface depression, broken teeth, etc., especially note that the effective length of the tightening between the pipeline thread and the connector will affect the reliability of the seal , Pay attention to the effective length of the pipeline when purchasing. The effective length of ordinary DN15 cylindrical pipe thread is about 10 mm.

Gate valves and ball valves are generally marked with a nominal pressure on their valve body or handle. You can purchase them according to your needs.

If consumers want to replace the existing gate valve or ball valve, they must figure out the length of the structure, so as not to be unable to install it after purchase.

5. The triangle valve pipe thread has two types: internal thread and external thread. Consumers can choose and buy according to their needs. It should also be noted that some of the triangle valves made of zinc alloy on the market are sold at a lower price than ordinary valves. It is easy to corrode and cause breakage. After long time use, the pipeline will rot and make maintenance difficult.
