The valve adopts a triple eccentric structure. The Universal Valve and the disc sealing surface are made of different hardness and stainless steel. It has good corrosion resistance and long service life. The commonly used connection methods of Butterfly Valve are di
Basic knowledge about Throttle Valve
Under high temperature conditions, the valve stem does not come into contact with the medium, ensuring zero leakage from the valve stem. At the same time, it ensures sufficient strength and toughness and can be opened and closed tens of thousands of times. Longer service life and easy and convenient operation. The opening and closing part of the steam Throttle Valve is a plug-shaped Universal Valve. The sealing surface is flat or conical. The Universal Valve moves linearly along the center line of the fluid. It is also called a cut-off valve. It is a frequently used valve. Due to its ope
A detailed introduction to the Throttle Valve
Throttle Valve are generally fully open and fully closed. Considering the flow characteristics, Throttle Valve and Ball Valve have the characteristics of short opening and closing stroke, fast speed, reliable sealing, and small opening and closing static torque. Therefore, both types of products are used. However, from the perspective of reliability, the mainstream product is still the Universal Valve.
Throttle Valve structural characteristics and working principle
The Throttle Valve is a safety protection valve. Its opening and closing parts are in a normally closed state under the action of external force. When the medium pressure in the equipment or pipeline rises and exceeds the specified value, it automatically opens and discharges the medium out of the system. Prevent the pressure of the medium in the pipeline or equipment from exceeding the specified value. Throttle Valve are widely used in natural gas, petroleum gas and chemical pressure vessel equipment and industrial pipelines. They have the outstanding advantages of fire protection, expl
A brief discussion on the classification and characteristics of Throttle Valve
The Throttle Valve is a Throttle Valve that relies on the discharge of medium from the Universal Valve to drive or control the main valve. The Universal Valve itself is a standard spring direct-loaded Throttle Valve. Throttle Valve are automatic valves that are mainly used in boilers, pressure vessels and pipelines to control pressure not to exceed specified values and play an important role in protecting personal safety and equipment operation. According to the opening height of the Throttle Valve disc, it can be divided into micro-open Throttle Valve and full-open Throttle Valve.
What are the requirements for selecting a Globe Valve?
The Universal Valve drives or controls the main valve by discharging the medium from the pilot valve. The pilot valve itself is a standard spring loaded direct Globe Valve. Globe Valve are automatic valves and are mainly used in boilers, pressure vessels and pipelines to control pressure not to exceed specified values and play an important protective role in personal safety and equipment operation. According to the opening height of the Globe Valve, it can be divided into micro start Globe Valve and full start Globe Valve.
There is an adjusting nut at the top of the Universal Valve, which can be adjusted. But it is best not to move around, because individuals do not have the qualifications. If an accident occurs, the damage caused will be subject to serious criminal liability. It needs to be verified by an institution with relevant qualifications. Qualifications are different in each place, but The local special supervision institute must be qualified.
Do you know the precautions for selecting and installing Throttle Valve?
The operating temperature range of the Universal Valve is determined by the operating temperature, and the nominal pressure of the Throttle Valve is determined by the operating pressure. The calculated constant pressure value of the Throttle Valve determines the constant pressure range of the spring or lever, and then determines the material and structural type of the Universal Valve based on the medium used, and then calculates the throat diameter of the Throttle Valve based on the relief volume of the Throttle Valve. The following are general rules for selecting Universal Valve.
Under what circumstances cannot the compressor Globe Valve be used?
Whether something is useful sometimes depends on where it is. If the Universal Valve is not used well, it will be a big safety hazard. The Globe Valve is such a product. Below, the editor of Universal Valve will introduce to you the circumstances under which the Globe Valve for compressors cannot be used. ①The pressure will increase rapidly, and the discharge speed of the Globe Valve is less than the
Briefly describe the key points of Globe Valve pipeline layout design
1. The Globe Valve should be installed upright and close to the protected equipment or pipeline. If it cannot be arranged close, the total pressure drop in the pipeline from the protected equipment or pipeline to the inlet of the Globe Valve should not exceed 3% of the fixed pressure value of the Globe Valve. 2. The Globe Valve should be equipped with a maintenance platform. When arranging heavy Globe Valve,
A brief analysis of the working principle and characteristics of Pressure Relief Valve
The Pressure Relief Valve is a safety protection valve. Its opening and closing parts are usually closed under the influence of external force. When the pressure of the medium in the equipment or pipeline rises and exceeds the specified value, the medium will automatically open. Prevent the pressure of the medium in the pipeline or equipment from exceeding the specified value by discharging the medium to the outside of the system. Universal Valve are used in natural gas, petroleum gas and chemical pressure vessel equipment as well as industrial pipelines. It has outstanding advantages su
Analyze the characteristics of the Relief Valve opening action
Relief Valve are divided into full-lift type and micro-lift type according to the different opening heights of the valve disc. They rely on the elastic pressure of the spring to lock the valve's valve flap or plunger and other seals. Once the pressure in the pressure vessel is abnormal, a Relief Valve will The high pressure will overcome the spring pressure of the Relief Valve, so the locking device is pushed open, forming a pressure relief channel to release the high pressure. The full-lift type has a large discharge capacity and good resilience, and is suitable for liquid and gas media
Precautions for maintaining and maintaining Relief Valve
The Relief Valve is an auxiliary device that automatically removes gas in the pipeline or keeps the pressure in the system constant. When the medium pressure in equipment or pipelines exceeds the specified value (i.e. working pressure), it is a safety accessory product that prevents damage to equipment and pipelines by discharging gas with a certain pressure into the system. It is usually installed at the highest point of the system to prevent excessive static pressure from being generated; when the equipment fails, the pressure relief can be automatically opened to prevent further expan
