1. What is dust explosion preventionWhat is dust explosion prevention? It means that when dust is within the explosion limit and encounters a heat source (open flame or temperature), the flame instantly spreads throughout the entire mixed dust space. The chemical reaction speed is extremely fast, an
As an actuator of automation instruments, the use of solenoid valves has increased dramatically in recent years. This article analyzes the main characteristics of solenoid valves, and briefly summarizes the development trends of mature technologies in China from the perspective of application, exami
Common faults of overflow valves in use include noise, vibration, radial clamping of valve core, and pressure regulation failure.（1） Noise and vibrationThe components that are prone to noise in hydraulic devices are generally considered to be pumps and valves, with relief valves and electromagneti
1. Corrosive media: Plastic king solenoid valves and all stainless steel should be selected; For strongly corrosive media, isolation membrane type must be selected. Example CD-F.Z3CF. Neutral media, it is also advisable to use copper alloy as the valve shell material for solenoid valves, otherwise r
Many people think that electric valves are expensive and have high operating costs. However, this is not the case. If we calculate as a whole, traditional valves require many accessories and pipeline installations, and their prices do not have an advantage. Instead, they have to bear more maintenanc
The malfunction of the solenoid valve will directly affect the operation of the switching valve and regulating valve. Common faults include the solenoid valve not operating, and should be investigated from the following aspects:(1) If the wiring head of the solenoid valve is loose or the wire head f
The piston type steam solenoid valve is a step-by-step direct pilot solenoid valve, which can be divided into normally closed solenoid valves and normally open solenoid valves according to the different open and closed states when the power is cut off. Normally closed solenoid valve, after the coil
An emergency shut-off valve for ammonia is a new type of valve product developed by absorbing the advantages of many other valves. It combines the advantages of globe valves, check valves, solenoid valves, and pneumatic valves, and has the characteristics of simple structure, sensitive response, and
Recently, four types of high-speed railway specialized valves developed by the 695 Factory of Henan Aerospace Industry Corporation of China Aerospace Science and Industry Corporation successfully passed the audit of Beijing Saide High tech Railway Electrical Technology Co., Ltd. with a high score of
Electric valves, manual valves, and pneumatic valves are widely used to save energy consumption, while the latter two types of valves have lower installation costs and efficiency than electric valves. The advantages of electric valves are high operating efficiency and energy-saving consumption.Due t
In recent years, the sales of solenoid valves have surpassed those of regulating valves, mainly due to the sharp increase in demand for various specialized solenoid valves. Below are introductions by media category:(1) Gas solenoid valveDue to the adjustment of fuel structure in our country, the pro
