Gate valve in the use of occasions and manufacturers in the choice of factors

Choice of gate valve In recent years, the gate valve as a tool to control the direction of water flow and water, its form has also changed. In the past commonly used flashlight dual-purpose gate valve is gradually replaced by flashlight dual-use butterfly valve, butterfly valve has the advantages of small size, light weight, easy installation, drag coefficient. The disadvantage is that if the processing and installation accuracy is not enough, or when the water is more likely to lead to the butterfly valve is not tight, there is leakage phenomenon, while the traditional gate valve is not easy to leak, but the bulky; especially large diameter gate valve, large and bulky, installation and removal Are inconvenient; more importantly, due to bulky, resulting in increased pump room area, the project cost increases. Therefore, pumping station design, bidding and selection of valves should consider the following two issues: a use of occasions not subject to site restrictions, more debris in the water, easy to plug the important position of the valve, dual-use flashlight valve can be used; otherwise it can be used In particular, the butterfly valve can be used as a butterfly valve in the pumping station reconstruction project in order to effectively utilize the space of the original pumping station and achieve the purpose of increasing the water supply and discharge volume under the premise of unchanged original pumping station area. Two manufacturers choose a larger, longer production life, stresses credibility, quality clearance and is responsible for installation and commissioning of the valve manufacturer. With the continuous improvement of the precision of the butterfly valve, the quality will get better and better, and the water leakage problem will be solved. At that time, the butterfly valve will replace the old gate valve, which is the development trend of valves.
Nozzle Cap is also called filter cap, drain cap, water cap, and backwash filter. It is used in the filter water distribution system and filter.

The stainless steel nozzle cap is a perfect replacement of the traditional plastic water cap in water treatment equipment. Our nozzle cap is a new generation of products in the water treatment equipment industry. The stainless steel nozzle cap enjoys the advantages of large circulation area (about 2-3 times of the same size plastic slot cap), long service life, safe and reliable, low comprehensive cost.
