Product Name: ZCZP steam solenoid valve
Product model: ZCZP-16C
Product category:
Solenoid valve

purpose
ZCZP steam solenoid valve applies to the steam as the heating medium, automatic temperature control of the implementation of the agency. The steam boiler, radiator, dryer and other steam equipment and all kinds of temperature control instrument, steam shaping machine, steam dye machine, steam resurgence machine and other complete sets of equipment steam boiler pipe two position automatic control and remote control area. Widely used in automatic control system of dyeing, textile, food, medicine, tobacco, cement, petrochemical, metallurgy and other departments.

main features
Heat resistance: electromagnetic parts, seals part of the special resistance to temperature control electrical materials and sealing materials, and applied a variety of insulation measures.
Wear resistance: material selection is reasonable, valve cup and guide sleeve skillfully use fluid lubrication, reduce wear and tear.
Condensation resistance: the condensed water of steam pipe is an important factor affecting the operation of steam solenoid valve, and the valve is not affected by condensate water.

Structure principle
ZCZP steam solenoid valve is composed of two main parts of auxiliary valve and main valve, which is the pilot type two times opening solenoid valve. It depends on the opening and closing of the auxiliary valve to control the on-off of the main valve. According to the switch state when the power switch is different, it can be divided into normally closed solenoid valve and normally open solenoid valve. Normally closed solenoid valve, the power of normal position, the auxiliary valve port is closed, the main valve is cut off, when the signal into the pilot valve coil, the movable iron core is driven by electromagnetic force vice valve open suction mouth, rapid disappearance of the main valve valve cup pressure, medium pressure to the main valve valve cup holder, open the main the valve port, hard working medium circulation. But when the electric signal disappears, the movable iron core is reset, closing the auxiliary valve port, and the working medium self balancing hole enters into the valve cup. When the pressure tends to balance, the valve cup is moved down by the main valve spring, the valve cup self weight and the medium pressure, and the main valve port is tightly sealed, and the valve is closed. Normally open solenoid valve, in the power off position, by the role of the spring, vice valve opening, the main valve circulation. When the signal into the auxiliary valve coil, the movable iron core electromagnetic suction effect, the auxiliary valve port is closed, the working medium by balancing hole into the valve cup, when the pressure tends to balance, on the main valve spring, valve cup self weight and the medium pressure valve sealing cup down, close the main valve port, the valve is closed state. When the main valve is powered off, the electromagnetic force disappears, the vice valve opens, the main valve cup pressure disappears rapidly, the medium pressure will be the main valve cup support, open the main valve port, medium circulation, the valve is open.

Installation instructions
1, install the solenoid valve coil up and maintain the vertical position, solenoid valve on the arrow or marker should be consistent with the pipeline flow, shall not be installed in a splash of water or Water Leakage place.
2, the electromagnetic valve work without particle impurities, solenoid valve on the surface of the dirt and filter, need to regularly clean.
3, in the solenoid valve failure, in order to isolate the solenoid valve in time, and ensure the normal operation of the system, good installation of bypass devices (Figure 1).
4, in the pipeline system, the solenoid valve installed on the branch should be smaller than the diameter of the main pipeline valve (Figure two).
5, before the installation of solenoid valve, the pipeline must be cleaned. It is recommended to install filter in front of valve and install drain valve in steam pipe.
6, can not be concave valve installed in the pipeline, so as to avoid condensation of water vapor, impurities deposited on the valve and prevent action.
7, ordinary type can not be used in explosive dangerous occasions.
8, in the case of lack of rigidity of the pipeline, it is recommended to fix the pipeline before the valve, so as to avoid the vibration caused by the solenoid valve working.
9, before installation, should pay attention to see the product signs, carefully read the instructions, to determine whether the product meets the conditions of use.
10, solenoid valve before and after the installation of pressure gauges on the pipeline, in order to observe the pipeline pressure.
