How to assemble the gate valve signal box, what is the explosion proof signal gate valve, and how to

Take a look for yourself, I don't understand.

The actuator manufacturer will help install it.

Here are some of the well-known brands recognized in the valve industry, which are widely recognized and have a high reputation. While rankings may vary depending on time and market conditions, the following brands are generally considered to be among the top brands in the valve industry:

The following influential first-line brands of water system valves and industrial valves can be used as a reference, but for reference only: Suzhou Neway Valve, Shanghai Guanlong Valve, Shanghai Qizhong Valve, Sanhua, Su Yan, Shentong, Su Valve, Nanfang, Jiang.

First, the word Yao. The above manufacturers are only estimates and references, and the specific situation may vary or fluctuate at any time due to changes in a series of factors such as changes in the market, the size of the competition pattern, and the stability of product quality. As an indispensable key device in industrial production and civil facilities, the quality and reputation of the valve brand directly affect the satisfaction and trust of users.

These brands are known in the valve industry for their innovative technology, high-quality products and reliability. It is important to note that the market and industry are evolving rapidly, and different rankings may vary depending on time and region. For the most up-to-date ranking information, it is recommended to refer to industry reports, professional organizations or market research data for more detailed and accurate information.

The function of the signal box in the gate valve: under the action of the remote 24VDC power supply, the gate valve is remotely controlled to adjust the opening angle or opening and closing. The gate valve is generally used in the water pipeline of the fire protection system, and there is a group of gears in the signal box, and the main gear in contact with the gate valve screw is driven by the other gears in the box under the drive of the 24V power supply.

Signal butterfly valves, the flange and the valve body are not together and what you normally see is one.

The blue one is single.

The valve body is copied, and the red one is the welded flange on the pipe. There is rubber on the valve body to seal with the flange face. This is determined by the structure of the butterfly valve, which is usually installed in this way for small-diameter butterfly valves below DN150.

There are also those with flanges, but they are much higher. Small-caliber butterfly valves are usually used in places where the pressure is not high and the leakage requirements are not high, so they rarely use their own flanges. The ones with their own flanges are generally used in petrochemical systems and have a much higher pressure level.

The signal valve is installed in accordance with GB50261-2005.

5 4 6 The signal valve should be installed on the pipe in front of the water flow indicator, with.

The distance between the plates of the water flow indicator is right.

It should not be less than 300mm.

For the installation of other valves, the specifications, models and installation positions of the control valves should meet the design requirements, the installation direction should be correct, and the control valves should be clean, no blockage, and no leakage; The main control valve should be marked with opening and closing, and the control valve in the concealed place should be marked with a sign indicating its location in a conspicuous place.

1. The installation of the exhaust valve should be carried out after the pressure test and flushing of the system pipe network are qualified, and the exhaust valve should be installed at the top of the water distribution main pipe and the end of the water distribution pipe, and should ensure that there is no leakage.

2. The water flow direction of the pressure reducing valve should be consistent with the water flow direction of the water supply pipe network, and the filter should be installed on the water inlet side, and the control valve should be installed before and after it; The adjustable pressure reducing valve should be installed horizontally, and the bonnet should be upward; Proportional pressure reducing valves should be installed vertically: when installed horizontally, the orifice of the single breathing port pressure reducing valve should be downward, and the orifice of the double breathing pressure reducing valve should be in a horizontal position.

3.When installing other control valves, a certain distance should be maintained to facilitate maintenance and management, and when installing a multi-functional pump control valve without a pressure gauge, a pressure gauge should be installed in the adjacent parts before and after it; A filter should be installed before the inlet of the backflow preventer or a backflow preventer with a filter should be used, and gate valves should be installed at both ends of the backflow preventer, and flexible joints should be installed at at least one end;

For the clamp type, the two flanges on the pipe are pulled in with studs, and the butterfly valve is in the middle.

Check the instructions that arrived with the goods.

The instruction manual contains an electrical diagram and wiring diagram.

Illustrate the wiring according to the wiring diagram

This one is red, so you have to find a place that specializes in selling firefighting pipe fittings to buy it

With the input module, it is good to connect the normally open contact on the gate valve (when opened) and the water flow to the input module.

If the fire signal valve needs to be wired, the signal valve needs to feed back its signal to the fire alarm controller through the monitoring module when it is moving, and electricity is needed to operate. In addition to the advantages of elastic seat seal gate valve, the special signal gate valve for fire protection can intuitively display the degree of valve opening, so that the opening of the valve can be judged at a distance and corresponding measures can be taken in time. The opening and closing are fast and reliable, so they are often used in fire protection systems.

If the fire signal valve needs a feedback signal, it only needs to connect the input module and the alarm line, which is basically the same as the detector.

This can be installed horizontally, but not on or near the protective wall, because according to the regulations, the pipeline passes through the protective wall, and the protective sleeve and explosion-proof wave valve need to be set, and the fire valve is installed behind the explosion-proof valve.
