Introduction of one-way butterfly valve
One-way butterfly valves and non-return butterfly valves are one kind of valves, they have different functions but similar shapes. The following will detail the use of these two valves, materials, advantages and disadvantages, maintenance and maintenance and how to choose the manufacturer.
One way butterfly valve
1. Use
The one-way butterfly valve is also called the reverse butterfly valve, which is suitable for controlling the flow direction of the fluid in the one-way flow pipeline to prevent the reverse flow of the fluid resulting in system failure. It is usually installed at the outlet of the pump to prevent backflow.
2. Material
The main materials of the one-way butterfly valve are carbon steel, stainless steel, aluminum, copper and cast iron, etc. The corresponding materials are selected according to the requirements of the actual working scene.
Step 3: Pros and cons
The one-way butterfly valve has the advantages of simple structure, light weight, small starting torque and long service life. However, for scenarios with large fluid viscosity, its service life will be affected to a certain extent.
4. Maintenance
During use, the one-way butterfly valve should be regularly checked and cleaned to prevent impurities from entering and affecting its normal operation. If water leaks, replace components such as sealing gaskets in time.
Two, check butterfly valve
1. Use
The check butterfly valve is also called the check butterfly valve, which is suitable for preventing the reverse flow of fluid in the one-way flow pipeline, and preventing the pump, motor and other equipment from being damaged by the reverse flow.
2. Material
The main materials of the check butterfly valve are carbon steel, stainless steel, aluminum, copper and cast iron, etc. Select the corresponding materials according to the requirements of the actual working scene.
Step 3: Pros and cons
The check butterfly valve has the advantages of simple structure, long service life and small starting torque. However, because its ram can only be kept closed by the medium pressure, the effect is not good in some high temperature and high pressure scenarios.
4. Maintenance
In the process of use, the check butterfly valve should be regularly checked and cleaned to ensure that its ram is free to rise and fall, and the sealing performance is good. If it is found that the gate seal is not tight, it is necessary to replace the sealing washer and other parts in time.
5. Manufacturer selection
likv Valve is a professional valve manufacturing company, its production of check butterfly valve quality stability, excellent leakage performance, economic durability, strong adaptability, is the choice of manufacturers.
To sum up, one-way butterfly valves are suitable for use in one-way pipelines, and check butterfly valves are suitable for use in scenarios requiring counter-current prevention. When choosing a manufacturer, be sure to choose a manufacturer with a certain scale, technical strength and after-sales support, such as likv valve.
