Do you know the internal valve of the fully enclosed high and low temperature cycle device integrated machine?

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
