Risk of valve ajar

Harm of 1. valve half open The valve half open is actually the valve is not fully open or closed, partially open the case does not allow all the liquid or gas circulation. An ajar valve can cause the following problems: 1. Water flow is blocked or leaking When the valve is not fully opened, the normal water flow of the pipeline will be blocked or partially leaked, which may cause some water pressure instability and water flow blockage in the pipeline system, which will affect the water pressure and water supply quality, and will also bring water resources. Waste. 2. Reduce the reliability and safety of the pipeline system If the valve is half open, the pipeline system will be in an unstable state, and this unstable state will greatly reduce the reliability and safety of the system. Especially in important situations, this unstable state may cause serious consequences. 2. how to avoid the valve half open The half-open valve is extremely dangerous to the safety of the pipeline system. Therefore, some measures must be taken to avoid this situation: 1. Timely maintenance and inspection of pipeline system The valve half open is often caused by the untimely maintenance of the pipeline system and incomplete detection. Timely maintenance and inspection of the pipeline system can provide a basis for early detection and resolution of problems, thereby avoiding the occurrence of half-open valves. 2. Normal use of the valve Proper use of the valve is the key to preventing a half-open condition. In the valve operation, it is necessary to operate in accordance with the correct procedures and laws, follow the valve switching sequence, and pay attention to the operation essentials. 3. Commissioning before valve installation Before the valve is installed, it needs to be adjusted to ensure that the valve can be fully opened or closed. If it is found that the valve cannot be opened normally, it needs to be adjusted or replaced in time to avoid problems in subsequent use. 4. Strengthen staff training In the enterprise, it is necessary to strengthen the skills training of employees, especially the operators, to ensure that they can operate the valve correctly, and understand the relevant knowledge of the valve, so as to avoid the occurrence of the valve half open.

Why do you want to return a little after the valve is fully opened?

In the process of pipeline use, the role of the valve is to control the flow of fluid. However, before starting to use the valve, the valve needs to be fully opened to ensure smooth fluid flow. However, if the valve is fully opened directly, it is not conducive to the operation and use of the pipeline. Therefore, after the valve is fully opened, it is necessary to return a little, which can protect the valve and the pipeline. Specifically, there are two main reasons for returning a little: 1, to avoid the reverse pressure on the valve sealing surface damage The valve usually uses a sealing surface to control the flow of fluid. When the valve is closed, the sealing surface is used to prevent fluid from passing through the valve. When the valve is fully open, the sealing surface may be subjected to reverse pressure, resulting in damage to the sealing surface. Therefore, it is necessary to return to a point after the valve is fully opened, leaving a gap to reduce the impact of reverse pressure, thereby protecting the sealing surface of the valve. 2. Relieve the impact of pipeline pressure on the valve The fluid in the pipeline will be affected by various pressures during the movement. When the valve is fully open, the fluid pressure in the pipeline will impact the valve, which will adversely affect the valve and the pipeline. Back to a point can alleviate the impact of pipeline pressure on the valve, to protect the safe use of valves and pipelines. 2. back to the specific operation method The specific operation method of returning to a point is as follows: 1. Open the valve fully. 2, slowly close the valve until leaving a small gap. After waiting for a period of time, the valve is completely closed. It should be noted that in the process of returning to a point, it is necessary to operate slowly to ensure that the gap left is appropriate to prevent the normal use of the pipeline from being affected. 3. Summary Valve in the use of the pipeline is a very important part of the valve, the full open and back to a point for the smooth operation of the pipeline and the safe use of valves and pipelines have an important role. When the valve is fully opened, back to the role of a point is to protect the valve sealing surface and ease the impact of pipeline pressure on the valve. When the operation is back to a point, it needs to be carried out slowly and pay attention to leaving appropriate gaps to ensure the safe operation of valves and pipelines.

Valve Maintenance Procedure

1. Cleaning The surface of the valve, the trapezoidal thread on the valve stem and the valve stem nut, the sliding part of the valve stem nut and the bracket, and the gears, worm gears and other components are easy to accumulate a lot of dust, oil and media residues, which will cause wear and corrosion to the valve. Therefore, it is obviously very important to keep the external and active parts of the valve clean and protect the integrity of the valve paint. The dust on the valve is suitable for brush sweeping and compressed air purging. Trapezoidal thread and stolen goods between teeth are suitable for wiping with rag. Oil stains and residues on the valve are suitable for steam purging, even copper wire brushing, until the processed surface and mating surface show metallic luster, and the paint surface shows the natural color of paint. Trap should be responsible for a special person, check at least once per shift, regularly open the flush valve and trap at the bottom of the plug for flushing, or regularly disassemble the flushing, so as to avoid the stolen goods blocking the valve. 2. Lubrication of valve Valve trapezoidal thread, stem nut and bracket sliding parts, bearing parts, gear and worm gear, worm meshing parts and other cooperating parts, all need good lubrication conditions to reduce mutual friction and avoid mutual wear. Some parts are specially equipped with oil cup or nozzle. If it is damaged or lost in operation, it should be repaired and equipped, and the oil circuit should be dredged. Lubrication parts should be regularly refueled according to specific conditions. Often open, high temperature valve is suitable for intervals of a week to a month refueling once; not often open, the temperature is not high valve refueling cycle can be longer. Lubricant organic oil, butter, molybdenum disulfide and graphite. High temperature valve is not suitable for oil, butter, they will be due to high temperature melting and loss, and suitable for injection of molybdenum disulfide and wipe graphite powder. For exposed parts that need lubrication, such as trapezoidal threads, gears and other parts, if grease such as butter is used, it is easy to be contaminated with dust, while molybdenum disulfide and graphite powder are used for lubrication, it is not easy to be contaminated with dust, and the lubrication effect is better than yellow. Graphite powder is not easy to apply directly, a little oil or water can be used to adjust the paste. The plug valve of the oil filling seal should be filled with oil according to the specified time, otherwise it is easy to wear and leak.
