Many people prioritize stainless steel pumps when pumping seawater or saturated salt water. They feel that the stainless steel material is durable and does not require much maintenance, but it is faster to detect damage when used, and the stainless steel pump is severely corroded. Seawater is a very complex multi-component aqueous solution. The main elements in seawater include Na ions, K ions, CL...

1. Introduction to Y-type Filter Y-type filters are an indispensable filtering device in pipeline systems that transport media. Y-type filters are usually installed at the inlet of pressure reducing valves, relief valves, constant water level valves, or other equipment to remove impurities from the media and protect the normal use of valves and equipment. The Y-type filter has the characteristics ...

The small hole floating ball valve has the function of automatically opening and closing pipelines to control water level. This valve is made of high-quality copper material, with a small size and easy installation, high sensitivity for use, low head loss, and no water hammer phenomenon. It can greatly improve the utilization rate of the water tower (pool). For new water towers (pools), due to the...

Classification Divided by power Automatic valve: A valve that operates by relying on the force of the medium itself. Such as check valves, pressure reducing valves, drain valves, safety valves, etc. Drive valve: a valve that relies on external forces such as manpower, electricity, fluid power, and pneumatic power to operate. Such as globe valves, throttle valves, gate valves, butterfly valves, bal...

Shut-off valve Also known as a shut-off valve, it belongs to the forced sealing type valve and is a type of shut-off valve. There are three types of connection methods: flange connection, screw connection, and welding connection. The "three modernizations" of valves in our country once stipulated that the flow direction of shut-off valves should be from top to bottom, so there is directional insta...

The classification of valves can be divided by function, material, structure, pressure, diameter, connection method, and transmission method. The classification based on valve material is a common method of classification. According to the material of the valve body, valves can be divided into metal valves, non-metallic valves, and metal valve body lined valves. And metal valves are the most commo...

The installation and maintenance of butterfly valves should pay attention to the following matters: During installation, the valve disc should be stopped in the closed position. 2. The opening position should be determined according to the rotation angle of the butterfly plate. 3. For butterfly valves with bypass valves, the bypass valve should be opened before opening. 4. Installation should be c...

The flow rate and flow rate of a valve mainly depend on the diameter of the valve, and are also related to the resistance of the valve structure to the medium. At the same time, they are inherently related to various factors such as valve pressure, temperature, and medium concentration. The flow channel area of a valve is directly related to the flow rate and flow rate, which are interdependent qu...

As a throttling element, flow limiting orifice plates have the advantages of simple structure, easy processing, low manufacturing cost, and convenient installation. Under the premise of meeting the process requirements, using flow limiting orifice plates instead of regulating valves to limit flow or reduce pressure will greatly reduce investment and operation and maintenance costs. Therefore, they...
