Imported slurry valve is an efficient and reliable fluid control equipment, which is widely used in petroleum, chemical, metallurgy, electric power, pharmaceutical and other industries. It has the advantages of simple structure, easy operation, good sealing, corrosion resistance, high temperature resistance, etc., and can meet the requirements of various complex working conditions.
Generally speaking, the design of the imported slurry valve is compact, occupies a small space, is light in weight, easy to install, has perfect wear-resistant and anti-blocking measures, is easy to maintain, and has a long service life. It is usually in a clamp-on or monolithic construction, and the body seal is a "U" in a composite configuration"type and "t"type composite structure or "o.""Type composite sealing ring structure. The use of these structures enables the imported slurry valve to maintain high efficiency while also having good sealing and durability.
The wear-resistant and anti-blocking measures of the imported slurry valve include the following aspects:
The body and bonnet are made of high-strength materials, such as high-strength carbon steel, stainless steel, etc., which can withstand high pressure and corrosion resistance.
The seat is made of wear-resistant materials, such as wear-resistant alloys, ceramics, etc., which can effectively resist wear and corrosion.
The valve plate is made of high-strength, wear-resistant materials, such as high-strength carbon steel, stainless steel, etc., which can withstand the impact of high-speed flowing slurry.
The stem is made of high-strength, wear-resistant materials, such as stainless steel, which can withstand large tensile forces and pressures.
The sealing surface is made of wear-resistant and corrosion-resistant materials, such as wear-resistant alloys, ceramics, etc., which can effectively prevent slurry leakage and clogging.
The valve body is equipped with an anti-blocking device, which can effectively prevent the slurry from settling and clogging in the valve body.
The valve body is provided with a sewage hole, which can remove impurities and dirt in the valve body in time and keep the valve body clean and smooth.
Inlet slurry valve and inlet knife gate valve are two different valves, and there are some differences in their structure, working principle and use scenarios.
Structure: The valve seat of the imported slurry valve is rubber, and the edge of the ram is sealed in contact, and the valve can be pressurized in both directions, and there is no groove at the bottom, so that the valve does not block slag. The ram of the imported knife gate valve has a knife edge, and the valve can cut off the slurry in the medium when it is closed, and the ram can be easily closed without jamming.
Working principle: The imported slurry valve is mainly used to control the slurry, mud and other media with particulate matter, and its valve seat is sealed by the edge contact between the rubber and the gate valve, and the whole valve can be pressurized in both directions, and there is no groove at the bottom, which makes it not appear slag plugging during use. The imported knife gate valve is suitable for dry and clean gas or liquid, and its sealing gasket is usually made of metal gasket or elastic material gasket, when the valve is closed, the gasket is squeezed and tightly fitted to the sealing surface of the blade plate and the valve base to prevent the leakage of the medium.
Usage scenario: The structure of the imported slurry valve restricts that it can only be sealed with rubber, and the temperature must be 80, which is suitable for the use of slurry (liquid media such as clean water, sewage, etc.) pipelines. In addition to rubber seals, imported knife gate valves can be sealed with higher temperature fluoroelastomer (180 degrees Celsius), and can be processed into metal seals, which can be used on pipelines of more than 1000 degrees, and it is suitable for use in some pipeline environments with solid media.
In general, there are differences between the imported slurry valve and the imported knife gate valve in terms of structure, working principle and use scenarios, and it is necessary to select the appropriate valve according to the specific use environment and needs.
