How to solve the problem of manual butterfly valve leakage? Likv told you.

Manual butterfly valve is a type of valve, because of its simple structure, easy operation, easy installation, low cost and other advantages, is widely used in industrial pipelines. However, in the actual use of the manual butterfly valve may appear impact, corrosion, aging and other problems, resulting in its airtight performance is affected, resulting in leakage phenomenon. This article will explain how to solve the problem of manual butterfly valve leakage.

1. Cause analysis of air leakage

Before solving the problem of manual butterfly valve leakage, it is necessary to understand the cause of leakage. The main reasons for manual butterfly valve leakage are as follows:

(1) gasket aging: manual butterfly valve selection of different sealing materials, some of which in normal use will produce aging, hardening phenomenon, thereby losing the sealing performance, resulting in gas leakage.

(2) Valve body deformation: In the process of use, the manual butterfly valve body is affected by factors such as external force impact or pipeline temperature change, resulting in valve body deformation, and the compression force between the sealing gasket is no longer balanced, resulting in air leakage problems.

(3) Valve stem leakage: The manual butterfly valve stem uses the traditional sealing structure, which will cause loose seals or damaged seals, and it is more likely to cause air leakage.

2. The method to solve the problem of manual butterfly valve leakage

(1) Replace the gasket: If the manual butterfly valve gasket is found to be aging or damaged, it is necessary to replace the new gasket in time to ensure the sealing performance. When replacing the new gasket, you need to pay attention to the selection of materials, according to the pipeline medium and working conditions and other factors to select the corresponding gasket material.

(2) Adjust the valve body: If it is found that the manual butterfly valve body is deformed, resulting in uneven pressure distribution, it is necessary to adjust the valve body or replace the new valve body to ensure the flatness of the entire valve body.

(3) Replace the valve stem seal: When the seal of the manual butterfly valve stem is loose or damaged, resulting in air leakage, it is necessary to replace the valve stem seal in time to ensure the sealing performance. When replacing the new valve stem sealing material, it is necessary to choose a material with good quality, corrosion resistance and better sealing performance.

3. Measures to prevent air leakage of manual butterfly valve

In order to extend the service life of the manual butterfly valve and ensure the smooth progress of the project, the following measures should be paid attention to in the process of using the manual butterfly valve:

(1) Choose high-quality manual butterfly valve products to ensure that product materials, manufacturing processes and other aspects meet the corresponding standards.

(2) Regularly check the airtight performance of the manual butterfly valve, check whether the gasket, valve body, valve stem, etc., is aging, deformation, loosening and wear problems, if the problem is found, timely measures are taken to solve.

(3) Pay attention to prevent the impact and corrosion damage of the manual butterfly valve, avoid additional loads during operation, and ensure the structural integrity and airtight performance of the manual butterfly valve.

(4) When installing the manual butterfly valve, it is necessary to follow its design and installation specifications. In particular, the manual butterfly valve with large caliber needs to use accessories such as support and calming device during installation to ensure its normal installation and operation.

In short, while ensuring the daily maintenance of the manual butterfly valve, it is also necessary to pay attention to its installation and use process. Choosing the right manual butterfly valve products, mastering maintenance skills and standardized installation are important measures to prevent air leakage problems. For the problem of air leakage, it is necessary to start with the sealing gasket, valve body, valve stem and other aspects, and take effective solutions to eliminate hidden dangers in time to ensure the normal and stable operation of industrial pipelines and systems. likv Valve as a professional engaged in valve manufacturing enterprises, with advanced production equipment and technology, committed to providing high-quality manual butterfly valve and Hongcheng valve solutions and services, welcome users to inquire.
