1) installation location, height, import and export direction must meet the design requirements, threaded connection should be firmly tight. 2) All kinds of manual valves installed on the insulation pipe, the handle must not be down.

1) Remove the protective cover on both sides of the flange end and rinse and clean the valve in a fully open state. 2) Before installation should be in accordance with the specified signal (electricity or gas) for the whole machine test...

Flange connections are widely used in various industrial piping systems to join pipes, valves, pumps, and other equipment. However, like any mechanical joint, flanges are prone to certain faults that can affect the integrity and performance of the system. Understanding these common faults is essential for proper maintenance and timely repair.

The dielectric pressure before and after the check valve is close to equilibrium and "sawing" each other, the disc is often slapped with the seat, and some brittle materials (such as cast iron, brass, etc.) are broken by a disc.

Since ball valves are usually made of rubber, nylon and PTFE as seat sealing rings, the temperature at which they are used is limited by the material of the seat seal ring. The cutoff effect of the ball valve is accomplished by pressing the...

Advantages: (1) has the lowest flow resistance (the actual is 0); (2) because in the work will not get stuck (in the absence of lubricant), it can be used reliably in corrosive media and low boiling liquid;

In the complex system of modern industry, the precise control of fluids plays a pivotal role in the stable operation and efficient development of many fields. As one of the key components in the field of fluid control, the development history of check valve industry not only reflects the evolution of industrial technology, but also closely connects with the changes in the global economic pattern, environmental requirements and the needs of various industries. The following will provide an in-depth analysis of the development status, technological breakthroughs, market dynamics, challenges and opportunities faced by the check valve industry, and comprehensively demonstrate the vigorous vitality and future trend of this industry in the industrial wave.

Ball valve has long been washed by materials, resulting in friction, resulting in serious impact wear, can not meet the normal production, at the same time resulting in the shortening of equipment use period.

1. No friction between opening and closing. This feature completely solves the problem that the traditional [wiki] valve [/wiki] affects sealing due to friction between the sealing surfaces. 2. Mounted structure.

(1) The cut-off valve structure is simpler than the gate valve, manufacturing and maintenance are more convenient. (2) Sealing surface is not easy to wear and abrasion, good sealing, opening and closing disc and valve body...

In recent years, the ball valve has witnessed remarkable advancements, incorporating a host of new features that enhance its performance, durability, and versatility. These innovations have been driven by the ever-evolving demands of various industries, including oil and gas, chemical processing, water treatment, and more.

A strainer is a crucial component in many fluid systems, serving the essential function of removing solid particles and debris from the flowing fluid. Understanding its working principle is vital for ensuring the proper operation and longevity of the associated equipment and the overall system.
