Inox valves, cast inox material of the valve, has certain corrosion resistance, but met too much strong hydrochloric acid and other corrosive medium, inox 316 l is generally used only a few months or a few weeks, if there is a corrosive medium, suggest to buy four fluorine valve, cast steel liner than 316 l not only cheap, and the use of time will ... Inox valves, cast inox material of the valve, has certain corrosion resistance, but met too much strong hydrochloric acid and other corrosive medium, inox 316 l is generally used only a few months or a few weeks, if there is a corrosive medium, suggest to buy four fluorine valve, cast steel liner than 316 l not only cheap, and the use of time will greatly increase and valve factory tend to one year warranty.The fluorine valve is made of ordinary steel valves with special moulding process, and the four-fluorine sealing surface of the valve is increased by four fluorine. The sealing surface is compact and good, and the v-type PTFE packing combination is used to achieve zero leakage. The valve and stem are cast into one body, so as to avoid the possibility of the valve stem bursting out of the pressure part due to the pressure change, and the safety in use is guaranteed. Full plastic lining process, strong corrosion resistance of medium. View Details
Under what circumstance does urea pump solenoid valve not work?

The conveyor capacitance shrink or swell breaking, (start winding under this state does not work, work, running winding fingers pluck blade can rotate, shun dial clockwise rotation, backwash inversion. Replaced with capacitive) 2. Bearing wear, (after bearing wear makes the rotor shaking, rotor rotating magnetic field on the central axis, produces the phenomenon of reluctance rotor to rotate, must replace the bearing).Electricity is not changed hands does not turn, motor burning or without any movement: 1. The plug is not electricity, check whether the power cord in good condition, check whether the timer is not transferred to channel state 2. Winding overheating protection insurance on open circuit, apart of the stator end cover, where the tap density has little fingernail insurance, to pick out it will be short on both ends meet. 3. The rotor card dies, showing a clear blocking feeling for the rotating blade of the unplugged hand. When rotating the fan blade, stop, add lubricating oil or replace the bearing. 4. Winding circuit, even in the absence of anxious burnt flavour is also likely to make the winding damage, often appear the tap of the cause of the problem is due to the high temperature makes the solder oxide or other reasons, winding of copper clad aluminum wire poor contact directly disconnect, even be welding tap or replace the stator winding.

Installation of 4v solenoid valve:1. Before use, check whether the component is damaged during transportation and then install it;2. Please pay attention to the direction of gas flow and whether it is correct when installing. The medium must be filtered through a 40um filter;3.

Before use, check whether the component is damaged during transportation and then install it;2. Please pay attention to the direction of gas flow and whether it is correct when installing. The medium must be filtered through a 40um filter;3. Please pay attention to whether the installation conditions meet the technical requirements and then install them;4. Pay attention to the direction of gas flow during installation,P is the inlet port, A(B) is the working port, and R(S) is the exhaust port;5. Try to avoid using in a vibrating environment, and pay attention to anti-freeze measures at low temperature;6. When connecting to the pipe, pay attention to the winding of the stop belt should not exceed the end face of the joint, pay attention to remove the dust and iron dust in the pipe joint, and avoid impurities or foreign bodies into the valve body;7. Please pay attention to the dustproof, and suggest that the exhaust port should be installed with muffler or silencer. Remove the need to be in the inlet and outlet of the dust jacket.8. When the whole machine is debugged, it is recommended to use the manual device for debugging, and then the commissioning of the machine. View Details
Solenoid drain valve

Solenoid drain valve working principle: 1, when there is no pressure in the water, float close the inner chamber, by spring pressure, the condensate drain through 2, glass with pressure, when pressure is more than 1 KGF/cm2, overcomes the spring upward pressure, thus drain off, glass partition inside and the outside world. 3, water cup in condensat... Solenoid drain valve working principle: 1, when there is no pressure in the water, float close the inner chamber, by spring pressure, the condensate drain through 2, glass with pressure, when pressure is more than 1 KGF/cm2, overcomes the spring upward pressure, thus drain off, glass partition inside and the outside world. 3, water cup in condensate, when condensate collection to a certain extent, the float rises due to buoyancy and open the inner cavity hole, pressure inside the cavity, is under pressure and spring pressure, condensate through drainage catheter drainage.

1. The spring is damaged, and the spring on the pulse valve core is easily damaged, resulting in the appearance that the pulse valve is blowing in the nozzle for a long time, and the treatment is to replace the spring.2.

The spring is damaged, and the spring on the pulse valve core is easily damaged, resulting in the appearance that the pulse valve is blowing in the nozzle for a long time, and the treatment is to replace the spring.2. When the rubber pad is damaged, after long use, the rubber pad on the pulse valve core can be easily damaged, resulting in the appearance that the pulse valve has long been blowing into the nozzle, and the treatment method is to replace the rubber pad.Dirt 3, valve core, due to the air inlet is not clean, cause the valve core of dirt to accumulate knot, causing the appearance of injection port is long-term intake or after electric pulse valve not action, processing way is to clean the valve core.4. The diaphragm is damaged. After a long period of work, the diaphragm is easy to be tired and oxidized. The appearance of the diaphragm is the long-term release of the pressure relief valve. The pulse valve does not work.5. The throttle hole is blocked or damaged, and the air intake is not clean and easy to cause the blockage of throttling holes. The appearance is that the pulse valve has long been injected into the nozzle, and the treatment mode is to clean the throttle orifice. Orifice damaged or missing, the orifice loss of intercept, result in normal pressure and the appearance is some action after electric pulse valve, pressure relief vent mouth, but not for injection pulse valve, handling is a change of orifice.
