Direct acting timed drainage solenoid valve

Electromagnetic valve is an industrial equipment controlled by electromagnetism, which is an automation basic component used to control fluids. It belongs to the actuator and is not limited to hydraulic or pneumatic systems. It is used in industrial control system to adjust the direction, flow, speed and other parameters of medium. The solenoid valve can be combined with different circuits to achieve the expected control, and the accuracy and flexibility of the control can be guaranteed. There are many types of solenoid valves, and different solenoid valves play a role in different positions of the control system. The most commonly used ones are one-way valves, safety valves, directional control valves, speed regulating valves, etc.

The solenoid valve has a sealed chamber with through holes at different positions, each connected to a different oil pipe. The middle of the chamber is a piston, and there are two electromagnets on both sides. The magnetic coil on which side is energized will attract the valve body to which side. By controlling the movement of the valve body, different oil discharge holes can be opened or closed. The oil inlet hole is usually open, and hydraulic oil will enter different oil discharge pipes, and then push the piston of the oil cylinder through the pressure of the oil, The piston drives the piston rod, which drives the mechanical device. In this way, mechanical motion is controlled by controlling the current flow of the electromagnet.

An electromagnetic valve is a fluid control element that is controlled by the moving piston of an electromagnetic coil to attract electromagnetic force. It is an actuator for automated equipment pipelines. Below are illustrated working principles of a direct piston type electromagnetic valve and a pilot piston type electromagnetic valve, with manual reset electromagnetic network working principles and self holding electromagnetic valve and gas emergency cut-off electromagnetic valve working principles.

The 200X pressure reducing valve mainly controls the outlet pressure of the main valve by adjusting the pressure reducing pilot valve. The outlet pressure of the main valve does not change due to changes in inlet pressure and flow rate. The outlet pressure is safely and reliably maintained at the set value of the pilot valve, and the set value can be adjusted to achieve the purpose of reducing pressure in the pipeline. This valve has precise pressure reduction, stable performance, convenient adjustment, and long service life. Suitable for domestic water supply, fire water supply, and other industrial water supply network systems.

Brief introduction of 900X emergency shut off valve: 900X emergency shut-off valve is a kind of valve which is used in the water supply system of fire fighting water and domestic water in parallel, and is used in the direction of water supply by users. In case of fire, a large amount of water is urgently needed for fire fighting. Domestic water should be cut off immediately to ensure sufficient water for fire fighting; When the fire stop water pressure decreases, the valve will automatically open, in a normally open state, to restore domestic water supply. The system does not need to set up a separate fire water supply network, which greatly saves the construction cost and water consumption. The valve has high control sensitivity, safety and reliability, simple debugging and long service life.

The VB7000 electric two-way regulating valve is used for industrial and industrial fluid control in air conditioning, thermal ventilation, and heat treatment plants. There are two-way and three-way forms.

The telescopic butterfly valve has the function of automatically compensating for the thermal expansion and contraction of pipelines for easy loading and unloading. It is the best device for regulating flow and breaking fluid on industrial pipelines such as petroleum, chemical, power, papermaking, water supply and drainage, and municipal construction with temperatures below 425 ℃ and nominal pressures below 1.6 MPa. Features 1. Unique structure, flexible design, light weight, labor-saving, and quick opening and closing. 2. Telescopic butterfly valves not only have the function of compensating for thermal expansion and contraction caused by pipeline temperature difference contraction, but also provide convenience for valve installation and replacement during maintenance. 3. The sealing part can be adjusted and replaced, and the sealing performance is reliable.

Q47H ash discharge ball valve/Q947H electric ash discharge ball valve/Q647H pneumatic ash discharge ball valve are used in the extraction, refining, processing, and pipeline transportation systems of petroleum, natural gas, coal, and ore; In the production of chemical products, pharmaceuticals, and food; In the power production systems of hydropower, thermal power, and nuclear power; In the water supply, drainage, heating, and gas supply systems of cities and industrial enterprises; In the drainage and irrigation system of farmland; Widely applied in the metallurgical production system, it is an important mechanical product closely related to production construction, national defense construction, and people's lives. Ball valves are used in various pipeline systems to cut off or connect the flow of media, allowing the media to be transported to designated points according to predetermined procedures.

Product introduction: Emergency shut-off valve, also known as safety shut-off valve, means that in the event of an emergency, the valve will be quickly closed or opened to avoid accidents. The emergency shut-off valve is a normally open pulse-triggered solenoid valve, which has the functions of self-locking and manual reset.
