　　(1) Types of valves


　　1. Classified by role and use


　　(1) cut-off valve: cut-off valve is also known as closed circuit valve, shut-off valve, its role is to connect or cut off the medium in the pipeline. Cut-off valve types include gate valves, globe valves, plug valves, ball valves, butterfly valves and diaphragm valves, etc.


　　(2) Check valve: check valve is also known as one-way valve or check valve, its role is to prevent the backflow of media in the pipeline. Its main role is to prevent the backflow of the medium, to prevent the pump and drive motor reversal, as well as the release of the container medium. Water pump suction off the bottom valve also belongs to the check valve category.


　　(3) Safety valves: the role of safety valves is to prevent the pipeline or device in the medium pressure exceeds the specified value, so as to achieve the purpose of safety protection.


　　(4) Regulating valves: regulating valves include regulating valves, throttling valves and pressure reducing valves, whose role is to regulate the pressure of the medium, flow and other parameters.


　　(5) Diverter valves: Diverter valves include a variety of distribution valves and traps, etc., whose role is to distribute, separate or mix the media in the pipeline.


　　(6) Exhaust valves: Exhaust valves are essential auxiliary components in piping systems and are widely used in boilers, air conditioning, oil and gas, and water supply and drainage pipelines. They are often installed at high points or elbows to remove excess gas from the pipeline, improve the efficiency of the pipeline and reduce energy consumption.


　　2. Classified by nominal pressure


　　(1) Vacuum valve: refers to the valve whose working pressure is lower than the standard atmospheric pressure.


　　(2) Low pressure valve: refers to the nominal pressure PN ≤ 1.6Mpa valve.


　　(3) Medium pressure valve: refers to the nominal pressure PN 2.5, 4.0, 6.4Mpa valve.


　　(4) High pressure valve: refers to the valve with a nominal pressure PN of 10~80Mpa.


　　(5) ultra-high pressure valve: refers to the nominal pressure PN ≥ 100Mpa valve.


　　3. classified by working temperature


　　(1) ultra-low temperature valve: for the medium working temperature t<-100 ℃ valve.


　　(2) low-temperature valve: for the medium working temperature -100 ℃ ≤ t ≤ -29 ℃ valve.


　　(3) room temperature valve: for medium working temperature -29℃


　　(4) medium temperature valve: for the medium working temperature 120 ℃ ≤ t ≤ 425 ℃ valve.


　　(5) high temperature valve: for the medium working temperature t>450℃ valve.

The drip head is divided into three basic types according to its energy dissipation characteristics: (1) long runner drip head: the runner diameter is generally less than 1.0mm, length 50~60cm, or even longer, the water flow in the process of overcoming the side wall friction and energy dissipation. (2) Orifice drip head: generally inserted on the capillary tube, inlet and outlet diameter is very small, there is a large cavity in the middle, pressure water flow through the diffusion, contraction or rotation and other ways to consume the remaining energy. (3) Microporous capillary: there are two types of single-walled tubes and double-walled tubes. The former is drip irrigation through the micro-hole on the wall of the tube, the latter has two layers of wall, water from the main wall of the water outlet orifice into the auxiliary cavity, and then by the auxiliary wall of the orifice seepage, the auxiliary wall of the orifice is the main wall of the number of orifices 5 ~ 10 times. This is a special form of capillary pipe which has both water delivery and water discharge functions. It is mostly made of plastic. Due to the small size of the outlet orifice, it is easy to block.

On September 3, the 80th anniversary of the victory of the Chinese People’s War of Resistance Against Japanese Aggression and the World Anti-Fascist War, our company organized all employees to watch the grand military parade. The impeccably aligned formations, powerful and rhythmic strides, dignified and heroic troops, and advanced sophisticated equipment filled every employee with immense pride and excitement.


This magnificent parade not only demonstrated the nation’s strong defense capabilities but also highlighted the unity, determination, and uplifting spirit of the Chinese people. Each precise formation reflected countless hours of rigorous training, and every seamless coordination embodied unwavering dedication to excellence. This pursuit of perfection and meticulousness resonates deeply with the professional values we uphold in the water-saving irrigation industry.


Just as the parade exemplified precision and coordination, our company remains committed to providing accurate and efficient irrigation solutions. Every drop of water saved is our response to the national policy of energy conservation and emissions reduction; every optimized irrigation system is our contribution to agricultural development. We understand that water-saving irrigation is not only crucial for agricultural productivity but also integral to national food security and the sustainable utilization of water resources.


Watching the parade has strengthened our determination to contribute to the advancement of national agriculture. Inspired by the spirit of the parade, we will approach our work with even greater passion and professionalism. We are dedicated to developing and producing high-quality water-saving irrigation products, providing robust support for modern agriculture, and contributing to the national cause of water conservation.


In this new era and journey, we, as water-saving irrigation professionals, will stay true to our mission, embrace hard work, and create a brighter future through relentless efforts!
