  • What do you need to notice when selecting a flat gate valve?
    What do you need to notice when selecting a flat gate valve?
    Special attention shall be paid to the following points when selecting the flat gate valve:First, select the proper valve according to the actual application. For example, single or double gate valves are required for oil and gas transmission pipelines, and rising stem gate valves with guide holes can be selected if pipeline cleaning is required. For product oil transmission pipelines and storage equipment, single or double gate valves without diversion orifices are more appropriate.Second, consider the material of the valve. Different media have different corrosion, oxidation, abrasion and other properties on the valve. Therefore, proper valve materials shall be selected. For example, for corrosive media such as strong acid and alkali, the valve material with corrosion resistance shall be selected; For severe working conditions such as high temperature and high pressure, the valve material with good heat resistance and mechanical property shall be selected.In addition, the structure o...

  • Why is gate valve installation important in industrial piping?
    The installation of gate valves in industrial pipelines is very important for the following reasons:Control flow: the gate valve can accurately control the medium flow in the industrial pipeline and vessels to meet the requirements of industrial process and conditions. Fine control of flow can be realized by adjusting the opening of gate valve, which is helpful to optimize the production process and improve the product quality.Regulated pressure: According to the characteristics and working conditions of the medium, the gate valve can regulate the pressure of the medium to ensure the safe operation of the industrial equipment. In case of pressure fluctuation or abnormal conditions, the gate valve can quickly cut off or adjust the medium flow, so as to stabilize the system pressure and prevent damage to the equipment or affecting the product quality due to too high or too low pressure.Cut-off medium: the gate structure of the gate valve can cut off the flow of the medium and ensure the ...

    How to correctly select the flat gate valve?
    When selecting the flat gate valve, first understand the structure and characteristics of the flat gate valve. Flat gate valve is a kind of sliding valve with parallel gate, and the gate can be single gate or double gate with opening mechanism. The pressing force of the gate to the valve seat is controlled by the medium pressure acting on the floating gate or the floating valve seat. If it is a double-ram flat gate valve, the opening mechanism between the two rams can supplement this pressing force.The selection of flat gate valve shall be comprehensively considered according to the actual application requirements and working conditions. For example, the oil and natural gas transmission pipeline needs to select the gate valve with single gate or double gate. If the pipeline needs to be cleaned, the rising stem gate valve with single gate or double gate with diversion hole can be selected. For the transmission pipeline and storage equipment of refined oil products, the gate valve with s...

  • Does the opening and closing time of the gate valve affect the pipeline flow?
    Yes, the opening and closing time of the gate valve affects the pipeline flow. When the flow of medium in the pipeline needs to be adjusted, the flow can be controlled by opening or closing the gate valve. If the time to open or close the gate valve is too short, the flow will change too much, which will lead to the pressure fluctuation of the pipeline and the rapid change of the flow rate, and may cause impact and damage to the pipeline and the valve. If the gate valve is opened or closed for a long time, the change range of flow will be too small, resulting in inconspicuous regulation effect and affecting the stability and production efficiency of the process.Therefore, proper opening and closing time shall be selected according to actual conditions during operation. For some large valves, electric or pneumatic opening and closing are required to improve the accuracy and efficiency of adjustment. At the same time, when adjusting the flow, attention shall be paid to the relationship b...
