For water supply enterprises on the use of water supply pipe network valve requirements, from the water supply safety, advanced technology, water tightness, the authenticity of the test, the reliability of quality, operational flexibility, the price of reasonableness, after-sales service The guarantee, the consistency of the delivery and the establishment of a more complete inspection, reinspection system, put forward the choice of views on the supply pipe network valve. At the same time, the main problems of water supply valve are also analyzed and discussed with the actual production and the need of using. Water supply pipe network is composed of pipes and valves and other pipe accessories, accessories. According to a variety of needs (water pipe network, water pressure scheduling and deployment, maintenance and repair of water needs, the old and new pipeline connections, pipeline washing, etc.), the valve must be opened and closed every day. The service life and quality of the valve determine the normal operation of the pipe network, plays a decisive role in the pipe network and must be given high priority. As the pipe network is a bridge between the water supply enterprises and the majority of users. Therefore, it can be said that a water supply enterprise management is reflected in the normal operation of the pipe network; and the normal operation of the water supply network, but also with the valve life and quality are closely related. The following valve on the water supply network, make a few comments. The safety of water supply does not affect water quality is an important indicator of the valve selection. The part that the valve contacts with water mainly is the inner side of the valve body, the seal part, the valve plate, etc. At present, the sealing part produced by many manufacturers uses the rubber material. Commonly used rubber materials are NBR, Neoprene (CR) or Ethylene Propylene Rubber (EPDM). These rubbers are synthetic rubbers. In the synthesis process, to add more than 10 kinds of natural rubber and raw materials such as anti-aging agent additives. The final synthesis of rubber can be used for sealing water supply valves, we must look at whether this rubber is non-toxic, is in line with drinking water hygiene standards. As for the valve inside and valve plate and other parts, many manufacturers used the past paint method, only consider the rust problem, without regard to whether toxic. In practice, it has been found that in the water supply pipe network, the lining anticorrosive problem of the pipeline is solved, while the pipe network valve is not lined. Due to the precipitation phenomenon of water and the erosion and deposition of the iron bacteria in the water in the valve cavity and the valve plate, Some body walls appear hill-like accumulation phenomenon. Not only affects the quality of water supply, but also some of the main reasons for the lax valve. Therefore, it is required that these parts in direct contact with water should be sprayed with non-toxic paint, and it is best to spray the non-toxic epoxy powder by electrostatic spraying. In the choice of valves, we should first check whether there is non-toxic rubber and paint certification and inspection certificate, only with the above conditions of the valve, in order to ensure water quality without pollution, to ensure the safety of water supply.
