Basic introduction to Check Valve
The Check Valve regulates the flow of the medium and reduces the pressure of the medium by controlling the opening and closing degree of the opening and closing components in the valve body, and adjusts the opening and closing degree of the opening and closing components through the effect of the pressure behind the valve to keep the pressure behind the valve at a certain level. Within the range, when the inlet pressure changes continuously, the outlet pressure is maintained within the set range to protect subsequent life and production equipment.
Characteristics and applications of Check Valve
Simply put, the Check Valve uses an electric actuator to control the Universal Valve to open and close the Universal Valve. It can be divided into upper and lower parts, the upper part is the electric actuator, and the lower part is the Universal Valve. The operating force distance is larger than that of the electric Universal Valve. The opening and closing speed of the Check Valve can be adjusted. It has a simple structure and is easy to maintain. Due to the buffering characteristics of the gas itself during the operation, it is not easily damaged by jamming, but there must be a gas sou
Introduction to knowledge about Globe Valve
The closing part of the Globe Valve is a sphere, and the center line of the Globe Valve is rotated to achieve opening and closing of a Universal Valve. 1. Friction-free opening and closing: completely solves the problem of traditional Universal Valve affecting sealing due to mutual friction between sealing surfaces; 2. Top-mounted structure: The Universal Valve installed on the pipeline can be directly
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 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.
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.
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
What is the structural principle of the Relief Valve?
The Relief Valve is a general-purpose valve that uses the force of the elastic element and the action of the mechanical device to maintain the medium pressure within a certain range for protection. The Universal Valve consists of an actuator (also known as a control mechanism) composed of diaphragms, pistons or levers, a positioner connected to the adjusting screw, and an exhaust port connected to the housing; the function of t
