    The fully enclosed high and low temperature cycle device is a machine and equipment used in industry to control temperature.
    Its main purpose is to ensure that the temperature is within a reasonable range, which provides great help for industrial production
    .

    It is mainly a heat conduction device, which can transfer heat in time
    .

    When it is necessary to close or open the fully enclosed high and low temperature circulation device integrated machine, a valve is required
    .

    The main function of the valve is to control the flow and direction of the refrigerant, and the valve should be installed where it is easy to disassemble and maintain
    .

    When installing various valves, please pay attention to the flow direction of the refrigerant and do not install them backwards
    .

    Among them, the thermal expansion valve must also be installed horizontally.
    Pay attention to the connection of the inlet and outlet of the valve.
    Usually, a filter screen is installed at the end of the valve
    .

    If the thermal expansion valve is properly controlled, the position of the temperature sensing bulb is very important, and the bulb should be securely attached to a clean straw to allow good contact between the bulb and the straw
    .

    When installing a flanged valve in a fully enclosed high-low temperature cycle device integrated machine, high-pressure asbestos plates should be used to buffer the flange and valve flange.
    The thickness of the high-pressure asbestos plates should be determined according to the depth of the flange groove on the valve.
    When the groove is large and the groove is deep, a thicker asbestos plate should be used to prevent the gap between the concave and convex interface between them and the seal is not tight
    .

    When assembling the flange valve, please ensure that all bolts are evenly stressed, otherwise, the concave-convex interface is prone to deflection
    .

    Globe valves are installed so that the working fluid should flow from the bottom of the valve to the top
    .

    When installed on a horizontal pipe, the valve stem should be vertically upward or inclined at a certain angle, and the valve stem should not be downward
    .

    If the valve position is difficult to access or the position is high, the stem can be installed horizontally for ease of operation
    .

       When the check valve is installed in the fully enclosed high and low temperature cycle device, the valve core must be able to open automatically
    .

    For lift check valves, the centerline and horizontal plane of the spool valve should be perpendicular to each other
    .

    For swing check valves, the spool plate should be rotated and installed horizontally
    .

       Of course, when we buy a fully enclosed high and low temperature cycle device integrated machine, we need to take comprehensive consideration, such as technical strength, manufacturing capacity and after-sales service and many other factors
    .

    Don't just think about the price
    .
