Analyze the principle advantages of electric and pneumatic valves
In fact, many companies in China are not very familiar with water treatment and environmental protection equipment in sewage treatment projects. Nowadays, environmental pollution is so severe that many environmental protection colleagues are working hard for the sustainable development of China's environmental protection industry. The basic knowledge in the following environmental water treatment book is briefly disseminated for everyone. Below is an analysis of the principles and advantages of electric and pneumatic valves in the production pipeline process in the workshop.

Do you know the principle of a one-way throttle valve and where it is usually used?
This article mainly introduces the working principle of throttle valves. Before introducing the principle, let's briefly understand what a throttle valve is. Simply put, a throttle valve is a structure that regulates fluid pressure, regulating the amount of air entering the engine and adjusting the engine's output. What is a one-way throttle valve called? The throttle valve and one-way valve are connected in parallel to form a one-way throttle valve. A one-way throttle valve is a combination of a one-way valve and a throttle valve in parallel. The throttle valve does not function in the direction of the valve. In the opposite direction, the oil cannot pass through the check valve and has a throttling effect. It is usually used to control the return oil adjustment of the double acting cylinder. The throttle valve of China Electromechanical Industry Network is a type of valve that controls fluid flow by changing the throttle part or length of the throttle valve. Throttle valves and one-way throttle valves are simple flow control valves. In the hydraulic system of a fixed pump, the throttle valve and safety valve cooperate to form three throttle speed control systems, namely the throttle valve throttle speed adjustment system, the return oil throttle control system, and the bypass throttle speed control system.
Precautions for selecting corrosion-resistant pumps
The anti-corrosion pump should reasonably determine basic parameters such as pump flow and head based on the process summary. Usually, normal wear and speed changes of the pump are considered, which may lead to a decrease in lift. Therefore, when selecting a pump, the lift of the pump can have a margin of 2% to 5%.
How does a threaded check valve work
Thread check valve refers to a valve that automatically opens and closes the valve disc by relying on the flow of the medium itself to prevent medium backflow. It is also known as a check valve, one-way valve, backflow valve, and backpressure valve. The threaded check valve is an automatic valve that mainly functions to prevent medium backflow, prevent pump and drive motor reverse rotation, and discharge the container medium. The threaded check valve can also be used to supply pipelines to auxiliary systems where the pressure may rise above the system pressure. Thread check valves can be mainly divided into swing type thread check valves (rotating according to the center of gravity) and lift type thread check valves (moving along the axis).

Introduction to the classification of threaded fittings
Types of threaded fittings: a. Screw thread is a type of connection, where the connection is threaded. b. Screw thread fittings are divided into two categories: inner thread and outer thread c. Thread and threaded pipe fittings have the same meaning and are named differently.

Introduction to the structural features of threaded pipe fittings
The strength and toughness indicators of threaded pipe fittings are among the best among various steels, and their outstanding advantage is corrosion resistance. Stainless steel must be used in highly corrosive situations such as chemical papermaking, and of course, the cost is also high! The product is not born with this appearance, but has undergone continuous evolution and upgrading to make it so high-quality and widely used.
Three Correct Selection Methods for Quick Couplers
About the Correct Selection of Quick Couplers 1. Determine the joint based on the type and temperature of the fluid. The type and temperature of the fluid have a significant impact on the quality of the joint, so the selection should be tailored to local conditions. If the fluid is air, a quick coupling made of steel can be used. If the fluid is liquid, a quick coupling made of brass or stainless steel can be used. 2. Select appropriate joints based on the pressure of the fluid. The pressure of the fluid is also the key to selecting a stainless steel quick connector, and the pressure resistance of different structures of the connector varies. Correct usage of quick connectors 1. Conditions. The humidity of the working environment
