zczp solenoid valve manual, zczp solenoid valve principle structure

The function of zczp solenoid valve zczp solenoid valve is suitable for actuators that use steam as the heating medium for automatic temperature control. It can carry out two-position automatic control and remote control zone for boiler steam pipelines of steam heaters, radiators, dryers and other steam equipment as well as various types of temperature controllers, steam setting machines, steam dyeing machines, steam resurgence machines and other complete sets of equipment. Zczp solenoid valves are widely used in automatic control systems in dyeing, textile, printing and dyeing, food, medicine, cigarettes, cement products, petrochemicals, metallurgy and other departments. The characteristics of zczp solenoid valve are corrosion resistance: the main components, valve plug, valve body, etc. are made of stainless steel and cast steel, with good anti-corrosion performance. Heat resistance: Special temperature-resistant electrical materials and sealing materials are used for the electromagnetic part and sealing parts, and various heat insulation measures are applied. Wear resistance: reasonable material selection, the valve cup and guide sleeve cleverly utilize the lubrication effect of fluid to reduce wear. Condensation resistance: The condensation water in the steam pipeline is an important factor affecting the action of the steam solenoid valve, but this valve is not affected by the condensation water. zczp solenoid valve principle structure The solenoid valve is a pilot-operated secondary opening solenoid valve composed of two parts: the auxiliary valve and the main valve. It relies on the opening and closing of the auxiliary valve to control the on and off of the main valve. According to the different switching states when the power is off, it can be divided into normally closed solenoid valves and normally open solenoid valves. Normally closed solenoid valve, when the power is off and in the normal position, the auxiliary valve port is closed and the main valve is open circuit. When the electrical signal enters the pilot valve coil, the movable iron core is attracted by the electromagnetic force to open the auxiliary valve port. The pressure disappears quickly, and the medium pressure lifts the main valve cup, opens the main valve port, and the working medium can flow. But when the electrical signal disappears, the movable iron core resets and seals the auxiliary valve port. The working medium enters the valve cup from the balancing hole. When the pressure tends to be balanced, the main valve spring, the valve cup's own weight and the medium pressure make the valve cup lower. Move, sealing the main valve port tightly, and the valve is closed again. The normally open solenoid valve is in the normal position when the power is turned off, and the auxiliary valve port is opened by the action of the spring, allowing the main valve to flow. When the electrical signal enters the auxiliary valve coil, the movable iron core is sucked down by the electromagnetic effect, the auxiliary valve port is closed, and the working medium enters the valve cup through the balance hole. When the pressure tends to be balanced, the main valve spring, the valve cup's own weight and the medium The pressure causes the valve cup to move downward, sealing the main valve port tightly, and the valve is closed. When the valve is powered off, the electromagnetic force disappears, the auxiliary valve opens, the pressure in the main valve cup quickly disappears, the medium pressure holds the main valve cup, opens the main valve port, the medium flows, and the valve is open. zczp solenoid valve technical parameters item description working medium steam and other non-corrosive gas medium temperature (℃) ≤ 200 nominal pressure (MPa) 1.6 working pressure difference (MPa) 0.05 ~ 1.60.10 ~ 1.6 power supply voltage AC220V other specifications can be made special Ordering service life (10,000 times) ≥ 10 ≥ 5 ≥ 3 Nominal diameter (mm) 1520253240506580100125150 Rated flow coefficient (KV) 2.858.51218284570110180250 Leakage volume (ml/min) 1.534.569172840 Power consumption 50VA Explosion-proof mark DIIBT4 Explosion-proof certificate number CE991 010 qualifying Orifice connector internal thread M20×1.5 Ambient temperature -40～+60℃zczp solenoid valve connection size Nominal diameter DN internal thread connection Flange connection outline size -Φ1425148110121012611585651634 -Φ143218212011/4221152140100761834-Φ184018214011/2230165168110841834-Φ18501921622252190165125992034-Φ18652652411851451 182034-Φ18802763102001601322038-Φ181003733502201801562238-Φ181254163802502101842238-Φ18150440400285240211243 8-Φ22 z CZP solenoid valve installation instructions 1. When installing, the solenoid valve coil is upward and kept in a vertical position. The arrow or mark on the solenoid valve should be in line with the The pipes must flow in the same direction and must not be installed in places with splashing or leaking water. 2. The working medium of the solenoid valve should be clean and free of particle impurities.
