Control regulating valve

Electronic temperature control regulating valve： The ZZWPE type self operated electronic temperature control valve (suitable for large caliber and heat transfer oil control), the biggest feature of this valve is that it only requires a regular 220V power supply, and utilizes the energy of the regulated medium to directly adjust and control the temperature of steam, hot water, hot oil, gas and other media.

Structure and principle of electronic temperature control regulating valve:
1. The regulating valve consists of three parts: the main valve, intelligent actuator, and sensor. According to user needs, there are two types of structures: heating type and cooling type.

2. The structure and principle of the heating type regulating valve are shown in the attached diagram:Before operation, the main valve core is in the semi open position, and the sensor is in State of nature. Connect the power supply and the main valve core heats the heat storage box. When the temperature rises to the corresponding set value, the sensor generates a linear signal input to the actuator, driving the valve core to gradually open, causing the medium to flow into the heat storage box according to parabolic characteristics, and heating until the set value. In this way, the controlled medium is always controlled within the set temperature range, thus achieving the purpose of temperature control.

Installation of electronic temperature control regulating valve:
(1) Before installation, the pipeline should be strictly cleaned and debris such as welding slag should be blown away, otherwise the valve will be severely damaged.

(2) The temperature regulating valve should be installed vertically on a horizontal pipeline, and the flow direction of the medium should be consistent with the arrow on the valve body.

(3) To ensure continuous operation of the automatic control system or valve maintenance, a bypass valve should be installed. A filter and pressure gauge should be installed in front of the valve, and a thermometer should be installed near the sensor for on-site monitoring and temperature setting.

(4) The sensor must be completely immersed in the controlled medium and installed horizontally or tilted upwards.

Debugging of electronic temperature control regulating valve:

(1) Connect to a 220V AC power supply. Open the main valve and slowly open the shut-off valve in front of the valve.

(2) Connect the bulb wire to the designated terminal post.

(3) Observe whether the change in set temperature is within the allowable range. If it is found to be too high or too low, the drive casing can be removed and the temperature setting switch can be turned (fine adjustment is sufficient). Repeatedly adjust. Until the temperature is controlled within the allowable range.

Gate Valve opens shuts is the damper plate, the damper plate heading and the fluid direction is vertical, the gate valve only can do all starts with the entire pass, cannot make the adjustment and the throttle. The damper plate has two packing surfaces, but the most commonly used pattern gate valve two packing surfaces form, the wedge-shaped angle wedge-shaped along with the valve parameter different, usually is 50, medium temperature not Gao Shiwei 2°52'.The wedge type gate valve damper plate may make a whole, the named rigid damper plate; Also may make can produce the micro distortion damper plate, improves its technology capability, the atonement packing surface angle the deviation which produces in the processing process, this kind of damper plate named elastic damper plate.The stainless steel gate valve material quality divides into 304 stainless steel gate valves, 316 stainless steel gate valves, 321 stainless steel gate valves.Expressed the method is: Z41H-16P.
