Description
Technical Field
The invention relates to a detection system, in particular to a convenient and efficient valve airtightness detection system.
Background
The valve is an important control part in a fluid conveying system and has the functions of stopping, adjusting, guiding, preventing counter flow, stabilizing pressure, shunting or overflowing and relieving pressure and the like. With the continuous optimization and upgrading of the infrastructure and manufacturing industry in China, the requirements and requirements of industries such as petrochemical industry, natural gas, metallurgy, electric power, urban construction and the like on valves are higher and higher.
However, in the process of manufacturing and installing equipment, people often focus on main machine equipment, so that the quality requirement of the valve is neglected, especially the failure of the valve at a key part in some systems can cause difficulty in production operation, increase the accident probability, and bring potential accident potential to safe production operation. Therefore, the valve should be tested for strength and sealing performance during the production process and before the installation of the valve. The sealing performance of the valve refers to the capability of each sealing part of the valve for preventing medium leakage, and is the most important technical performance index of the valve. Generally, the sealing position of the valve mainly has three positions: one is the contact position between the opening and closing piece and two sealing surfaces of the valve seat; one is the matching part of the packing, the valve rod and the packing box; one is the joint of the valve body and the valve cover. The first of these is called internal leakage, which affects the valve's ability to shut off the medium. The latter two leaks are called external leaks, i.e. leakage of medium from the inside of the valve to the outside of the valve. Whether the valve leaks internally or externally, the valve is not allowed, the service performance of system equipment is limited, and therefore the valve must have reliable sealing performance. The air tightness detection of the valve is a comprehensive quality control process technology in the production and installation processes of the valve, and the detection process and the detection equipment are required to have good stability and higher economical efficiency.
In practical application, the method for detecting the air tightness of the valve is mainly a pneumatic soaking method, a certain pressure medium (generally compressed air at normal temperature) is filled into the valve to be detected, then the valve is soaked in water or sprayed and coated with soapy water, and whether the workpiece leaks or the degree of leakage is judged according to visual inspection of the soapy water or bubbles in the water. Although the detection method is generally adopted, the detection method is extremely dependent on manual judgment, lacks of scientific rigor, cannot detect the internal leakage and the external leakage of the valve at the same time, and can cause physical or chemical damage to the detected valve, and the workpiece must be dried and subjected to rust prevention after the detection is finished, so that the production efficiency is low. In addition, in the existing technical means for detecting the air tightness of the valve, technical means for simultaneously detecting the air tightness of different types of valves are not shown, so that the universality of the valve air tightness detecting means is not strong. The existing detection system cannot meet the requirements of convenient and efficient production.
