        Imported high sensitivity steam pressure reducing valve (high precision pressure reducing valve)
        1. Imported high-sensitivity steam pressure reducing valve (high-precision pressure reducing valve) Product Overview
        Brand: US Ouke OKE
        High sensitivity steam valve reducing valve, also called high-precision steam valve reducing valve, is mainly used for steam pipelines. It is suitable for steam pipelines with large inlet pressure changes and large flow changes. By adjusting the adjustment spring pressure to set the outlet pressure, using the diaphragm to sense the outlet pressure change, the pilot valve is opened and closed by the pilot valve to adjust the overflow area of ??the throttle portion of the main valve to achieve the decompression and pressure reduction function, and the imported high sensitivity steam is reduced. The pressure valve (high-precision pressure reducing valve) increases the piston area in the ordinary pressure reducing valve, changes the throttling structure, changes the sealing form, improves the pilot valve structure and adjusts the spring form, and can be more sensitive and effective after the induction valve steam Pressure, effective high-precision pressure reduction of the post-valve pressure.
        Imported high sensitivity steam pressure reducing valve (high precision pressure reducing valve) features:
        1. Improve the sensing efficiency of the change of outlet pressure, improve the sensitivity, and greatly reduce the pressure deviation caused by the upstream pressure change, flow change and other factors.
        2. Improved streamline distribution and reduced noise.
        3. The sealing surface structure is improved and the life of the sealing surface is prolonged.

        Five, import high sensitivity steam pressure reducing valve installation instructions
        1. The steam pressure relief valve must be flushed and cleaned before installation. In order to prevent the welding slag, oxide scale and other sputum from flowing into the valve, affecting the normal operation of the valve.
        2. The steam pressure reducing regulator should be installed in a place convenient for operation and maintenance, and must be installed upright on the horizontal pipe. It should be noted that the flow direction of the medium in the pipeline is consistent with the direction indicated by the arrow on the valve body. .
        3. When the steam pressure reducing regulator valve is installed and used, the shut-off valve of the bypass pipe should be opened to eliminate the mixture of condensed water and soda water in the pipeline to prevent the garbage valve from being damaged when the pressure reducing valve is opened. When there is no abnormality, slowly rotate the adjusting screw clockwise to adjust the outlet pressure to the required pressure (based on the valve back pressure). After adjustment, tighten the lock nut and tighten the protective cover.
        4. A filter should be installed before the steam pressure reducing regulator to prevent debris in the medium from entering the pressure reducing valve and affecting its performance.
        5. There should be a straight pipe before and after the installed pressure reducing valve. The length of the straight pipe in front of the valve is about 600 mm, and the length of the straight pipe behind the valve is about 1000 mm.
        6. The steam pressure reducing regulator requires the inlet and outlet pressure difference to be ≥0.2Mpa.
        7. The pipe network of the steam pressure reducing regulator valve must be equipped with a safety valve to prevent damage to the system or equipment caused by the failure pressure of the pressure reducing valve.
