Butterfly Valve

Butterfly Valve

1. In the process of production and processing, scientific processing technology and advanced processing equipment are used to reduce or eliminate errors generated during processing.

2. Transfer the machining error, that is, transfer the error to the direction and other parts that have little or no impact on the machining accuracy.

3. The errors in the processing can be evenly distributed to the entire processed surface, so as to ensure that the error in a certain part is too large.

4. A new error can be created artificially to offset the original error. For example, if the original error is negative, a new positive error can be created to offset it.

How to repair the damage of the rubber elastic body of the butterfly valve

As a component used to realize the on-off and flow control of the pipeline system, the butterfly valve has been widely used in many fields such as petroleum, chemical industry, metallurgy and hydropower. In the butterfly valve technology that has been publicly employed, its sealing form mostly adopts a sealing structure, and the sealing material is mainly rubber. The continuous use of the rubber elastomer in the butterfly valve will cause tearing, abrasion, aging, perforation and even falling off, which will greatly affect the sealing performance of the butterfly valve. The previous repair method is through the hot vulcanization process, but it is difficult to meet the needs of on-site repair , In addition, special equipment should be used when repairing, which consumes a lot of heat and electricity, which is time-consuming and labor-intensive. Nowadays, the method of polymer composite materials is gradually used to replace the traditional methods, and the repair effect is better.

Types of Metal Seat Gate Valves

According to the sealing surface configuration, it can be divided into wedge gate valve and parallel gate valve. Wedge gate valve can be divided into: single gate, double gate and elastic gate; parallel gate valve can be divided into single gate Plate type and double gate type. Divided according to the thread position of the valve stem, it can be divided into two types: open stem gate valve and dark stem gate valve. 【 Resilient Seat Gate Valve 】 For industrial valves, the opening and closing parts of soft-sealed gate valves are gates. The movement direction of the gates is perpendicular to the direction of the fluid. The gate valves can only be fully opened and fully closed, and cannot be adjusted or throttled. [Principle of Resilient Seat] The resilient seat l gate valve is divided into two types: bright-stem resilient seat gate valve and dark-stem resilient seat gate valve. Usually there is a trapezoidal thread on the lifting rod, through the nut in the middle of the gate and the gui...

What is a knife gate valve?

Image
Knife gate valves are designed primarily for on/off and isolation service in systems with high suspended solids content. Knife gate valves are particularly suitable for handling slurry, viscous, corrosive and abrasive media. These valves have minimal pressure drop in the fully open position, they are easy to start, they have a relatively low weight and are cost effective.   When are knife gate valves used? Knife gate valves are commonly used in mining , power plants and in the paper, chemical and food industries. Knife gate valves have the advantage of being very compact due to the linear movement of the closing flap (the plate that stops the flow of fluid in the closed position). The knife gate valve is primarily a globe valve, although it can also be used as a control valve when the flapper valve is in the partially open position. Knife gate valves can be used for fluids containing solid particles, such as waste water or sludge. Generally, knife gate valves are designed to seal o...

Midline (concentric) The structural characteristics of the midline Centerline (concentric) The structural feature of the centerline is that the shaft center of the valve stem , the center of the gate, and the center of the body are in the same position. The structure is simple and the manufacturing is convenient. Common rubber linings belong to this category. The disadvantage is that the gate and the valve seat are always in a state of squeezing and scratching, large resistance distance, and fast wear. In order to overcome squeezing, scratching, and to ensure the sealing performance, the valve seat is basically made of elastic materials such as rubber, but the sealing material is also limited by temperature in use, which is why people traditionally think that it is not resistant to high temperatures. Applicable to the pipelines of petroleum, chemical, food, medicine, paper, water and electricity, ships, water supply, drainage, smelting and energy, etc., and can be used in a variety of ...
