Electric valve repair guide

First, the three fine motorized valve does not work after power Check the power supply connection is not good → re-wiring and connector connection Check the power supply voltage is within the scope of work → → tune the normal position of the coil is not desoldering → re-welding coil short circuit → replace the coil Working pressure difference is not appropriate → adjust the pressure difference → or replace the appropriate electric valve fluid temperature is too high → replace the electrically-driven valve is equivalent to the impurities so that the main valve core and the moving core stuck → cleaning, seal damage Should replace the seal and install the filter Liquid viscosity is too high, the frequency is too high and life has been to → replace the product Second, the electric valve can not close the main spool or iron core seal has been damaged → Change the seal fluid temperature, viscosity is too High → replace the electric valve counterparts have impurities into the valve to produce electric valve or moving core → cleaning spring has reached or deformed life → replace the orifice balance hole blocked → promptly clean the working frequency is too high or life has been to → re-election of products Or update the product Third, the other leaks → Check the seal is damaged, the spring assembly is not good External leakage → Loose connections or seals have been → screws or fasteners replace the head of the noise → loosening the seal is energized, tighten. Voltage fluctuation is not within the allowable range, adjust the voltage. Core suction surface impurities or uneven, timely cleaning or replacement.

Heat Meters

Jingcheng heat meters are measuring devices for a precise consumption metering. For measuring the heat which, in a heat-exchange circuit, is absorbed or given up by water called the heat-conveying liquid.From the start, we have developed innovative products based on the technology in dialogue with our customers. The result is a collection of well-engineered measuring instruments proved time and again in practice, because exact consumption values are only possible with precise measuring technology.

With our sophisticated line of products, we have set the standards in heat metering technology for years – and have done so with an eye on quality, the needs of our customers and an awareness for absolute precision.

The flowsensor measures the flow rater of the hot water passing through the heat exchange system and transfer the result to the calculator by pulse.The temperature sensor measures inlet temperature and outlet temperature of the heat exchange system.

There are three types of heat meters: woltman heat meter, multi-jet heat meter and ultrasonic heat meter.

1.Woltman heat meter:

.ultra reliable metering

.Excellent long-term stability and reliability

.Battery powered -10 years life expectancy

.AMR and cellular networks ready with various output model

.Programmable Display (units and outputs resolution)

2.Multi jet heat meter:

. ultra reliable metering

. Excellent long-term stability and reliability

. Battery powered -10 years life expectancy

. AMR and cellular networks ready with various output model

. Programmable Display (units and outputs resolution)

3.Ultrasonic heat meter

.Components: flow sensor,temperature sensor and calculator.
.No moving parts permitting the most reliable and longer term life;
.High accuracy in Class 2;
.Installation method:supply or return flow at horizontal.
