The characteristics of waterproof casing

1. Materials are more commonly used.
Before installing the waterproof casing, be sure to read the instruction manual carefully, double-check the model and specification of the solenoid valve, and install it step by step according to the instructions. The part material specified on the design drawing, by and large, determines the type of blank. For example, the part material is cast iron to use the casting method to manufacture the blank. For steel parts, the mechanical properties required for the material should be considered when selecting the blank. For example, the manufacture of waterproof casing parts should generally choose forgings or welded parts to ensure that the material has good mechanical properties.

2. Simple production process.
Waterproof casing structure switch is an important factor affecting the choice of blank, for example, the structure switch complex waterproof casing can be selected from castings. Size of the large waterproof casing can be selected sand casting; small size is used in the investment casting. Working waterproof casing in the half-open position, waterproof casing in the natural state. Connected to the power supply, waterproof casing full open. The medium flows from the direction of the arrow into the main waterproof casing, through the waterproof casing to the storage heat box for heating.
3. Protection of pipes.
When the temperature rises to the corresponding set value, the waterproof casing that produces the corresponding linear signal into the intelligent actuator, followed by driving the valve stem, waterproof casing displacement, close the waterproof casing to stop heating. When the temperature is lower than the set value, the waterproof casing that produces a linear signal into the actuator, drive the waterproof casing gradually open, so that the medium flows into the heat storage tank according to the parabolic characteristics, heating until the set value. Thus the controlled medium is always controlled within the set temperature range, thus achieving the purpose of temperature control.
4. Compact structure, easy installation.
Waterproof casing compact structure, small size, easy to move, easy to install, no need to build waterproof casing room, submerged in water can work, greatly reducing the cost of the project. Waterproof casing using double under the suction structure low water absorption level, due to the use of double suction double runner single worm shell structure, waterproof casing without axial tension, reduce and balance the light force, greatly improving the service life of waterproof casing 3 times, improve the use of efficiency 0.15.
