What is the difference between globe valve and gate valve?

The valve is a control component in the fluid delivery system, with the functions of cut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief. Valves for fluid control systems, from the most simple cut-off valve to a very complex automatic control system used in a variety of valves, its varieties and specifications quite a wide range. Globe valves, gate valves, butterfly valves, check valves and ball valves, etc. These valves are now indispensable control components in various piping systems. Each valve is different in appearance, structure and even functional use. However, there are some similarities between the cut-off valve and the gate valve in appearance, and both have the function of cutting off in the pipeline. Therefore, there will be many friends who have little contact with the valve to confuse the two. In fact, if you look closely, the difference between the globe valve and the gate valve is quite large.

China's valve industry has become a must for many industries in the production process

With the progress and development of science and technology, the speed of social and economic development continues to increase, and competition in various industries is becoming increasingly fierce. After decades of development, China's valve industry has made great progress in product development, performance, quality, reliability, and service. The valve industry is also developing in the direction of high automation, intelligence, multi-function, high efficiency and low consumption, and has become a necessary part of the production process of many industries. In recent years, China's valve industry has entered a period of rapid development, and the threshold of the valve industry has risen to become Asia's largest valve processing center and one of the world's largest valve markets. However, the per capita consumption level of China's valve products is not high in the world, currently only $22 per capita. However, with the rise of power station valves, chemical valves, valve building materials and food valves, we can see that the valve industry has broad prospects and the market is attractive.

Energy-saving regulating valve Low energy consumption Development direction

Energy saving to reduce energy consumption, improve energy efficiency is a development direction of the control valve. There are mainly the following development directions. 1. The use of low pressure drop ratio of the control valve. The proportion of the control valve in the entire system pressure drop is reduced, thereby reducing energy consumption. Therefore, the design of low pressure drop ratio of the control valve is one of the development directions, and the other development direction is the use of low impedance control valve. For example, a butterfly valve, an eccentric rotary valve, and the like are used. 2, the use of self-regulating valve: for example, the direct use of the pressure of the medium after the valve to form a self-control system, with the energy of the controlled medium to achieve pressure control after the valve. 3, the use of electric actuator control valve. Pneumatic actuators need to have a certain pressure during the operation of the entire control valve. Although small consumption amplifiers can be used, the gas consumption is still huge over time. The use of electric actuators, when changing the opening of the regulating valve, power supply is required, and power supply can no longer be supplied when the required opening is reached. Therefore, from the perspective of energy saving, electric actuators have obvious energy-saving advantages over pneumatic actuators.

Electric control valve how to control the various factors of the pipeline medium

Electric control valve is to use the power source to drive the electric actuator and then drive the valve to throttle, it is an important implementation unit instrument in industrial automation process control. With the increasing degree of automation in the industrial field, it is being used more and more in various industrial production fields. Compared with the traditional pressure regulating valve series, the electric regulating valve has obvious advantages: the electric single-seat regulating valve is energy-saving, environmentally friendly, and the installation is more quick and convenient. The electric control valve drives the differential pressure control valve series by receiving the signal from the industrial automation control system to change the cross-sectional area between the valve core and the valve seat to control the flow, temperature, pressure and other process parameters of the pipeline medium to realize the automatic adjustment function.

Issues to pay attention to when using manual valves

Manual valves are control components in fluid transport systems, used to change the cross-section of the passage and the direction of medium flow. They have functions such as guiding flow, shutting off, regulating, throttling, preventing backflow, diverting, or relieving pressure. Valves used for fluid control can range from very small instrument valves to industrial pipeline valves with a nominal diameter of up to 10m. 1. Opening and closing of manual valves: Manual valves are the most widely used type of valve. Their handwheels or handles are designed for ordinary human strength, taking into account the strength of the sealing surface and the necessary closing force. Therefore, long levers or wrenches should not be used to operate them. Some people are accustomed to using wrenches, but it is important to be careful not to apply excessive force, as this can easily damage the sealing surface or break the handwheel or handle.
