Signal gate valve principle Suiyou: The electrical equipment data signal device is a fully enclosed high-precision electromechanical engineering box structure, and stainless steel parts and domestic electrical components are selected in the box body. The device sits on the valve cap under the operating blind wheel, and is not easy to be hit.

The internal structure has a toggle switch and a promoter organization, and the transmission gear and the tooth mill spike wheel fixed in the valve stem are engaged in the transmission system. When the spindle is rotated to open and close the signal gate valve, the signal gate valve data signal device will "open" and "close" the electronic signal corresponding to the opening and closing parts of the gate valve.

A signal gate valve is a type of valve that can control the flow of fluid media by controlling the electrical or pneumatic signals of the control bucket. The principle is that the valve can be opened or closed under different electrical or pneumatic signals by receiving external signals.

Specifically, a signal gate valve is usually composed of an electromagnet, a valve body, and a control instrument, and its working principle is as follows:

1. When the control instrument sends out an electrical or pneumatic signal, the signal will be transmitted to the electromagnet or pneumatic actuator;

2. The electromagnet or pneumatic actuator generates the corresponding movement according to the force of the signal, so that the valve core or valve plate inside the valve body changes its position

3. The position change of the valve core or valve plate leads to the opening or closing of the valve, thereby controlling the flow of fluid medium.

The signal gate valve has the advantages of simple structure, high control accuracy and fast response speed, and is widely used in chemical industry, metallurgy, petroleum, water treatment and other fields.

Principle of signal gate valve: the data signal device of electrical equipment is a fully enclosed mold source high-precision mechanical and electrical engineering box structure, and stainless steel parts and domestic electrical components are selected in the box body. The device sits on the valve cap under the operator's wheel and is not easily hit.

The internal structure consists of a toggle switch and a promoter organization, and the transmission gear and the gear fixed in the valve stem are engaged in the transmission system. When the spindle is rotated to open and close the signal gate valve, the signal gate valve data signal device will "open" and "close" the electronic signal corresponding to the opening and closing parts of the gate valve.

The working principle of the magnetic locking valve is shown in the following figure:

It is composed of a spring, a lock, and a valve body, and the valve lock can be set on the valve casually, but can not be taken down casually

Four spring holes are arranged at equal intervals at the side end of the lock, and there is a spring that rests on the magnetic pin (ball) inside, and the letter "c" is placed on the lock valve key"Align with the magnetic lock cover"c"Plugged into the lock, then the lock valve key and the lock are fixed on the end of the lock and the lock on the corresponding magnetic pneumat, the valve stem on the valve body is provided with a rotary valve sleeve and the valve hole opened at the lower part of the lock coincides.

Gently press the magnetic lock with your hand, and you can open the magnetic lock with a light lift, and then you can operate the valve [door switch. When closing, simply insert the magnetic lock directly into the valve. Valve magnetic lock is a valve magnetic lock, which consists of a bonnet, a stem, a bonnet cap and a handle.

There is a connecting device on the bonnet cap and the stem, the bonnet is provided with a steel pin groove, a magnet is placed at the bottom, the magnet is sleeved in the spring, the steel pin is placed on the spring, and the bonnet.

The groove is provided on it, the handle is ring-shaped, there is no at least one pair of grooves and the corresponding bump on the outside of the bonnet cap and the handle, and the groove and the bump are consistent, and the opposite surface of the built-in magnet on the handle and the magnet in the steel pin groove is different magnetic poles. The valve magnetic lock has simple structure, reasonable design, convenient use, and effectively prevents abnormal opening and closing operation of the valve.

The working principle of the gate valve The opening and closing parts of the gate valve are the gate plate, the direction of movement of the gate plate is perpendicular to the direction of the fluid, and the gate valve can only be fully opened and closed, and can not be adjusted and throttled. The ram has two sealing surfaces, and the most commonly used mode gate valve has two sealing surfaces forming a wedge, and the wedge angle varies with the valve parameters, usually 5°, and 2°52 when the medium temperature is not high'。The gate plate of the wedge gate valve can be made into a whole, which is called a rigid gate; It can also be made into a ram that can produce a slight amount of deformation to improve its manufacturability and make up for the deviation of the sealing surface angle in the processing process, which is called an elastic ram.

When the gate valve is closed, the sealing surface can only rely on the medium pressure to seal, that is, the sealing surface of the ram plate is pressed to the valve seat on the other side by relying on the medium pressure to ensure the sealing of the sealing surface, which is self-sealing. Most gate valves are forcibly sealed, that is, when the valve is closed, the ram should be forcibly pressed against the valve seat by external force to ensure the tightness of the sealing surface. The gate plate of the gate valve moves in a straight line with the valve stem, which is called the lifting rod gate valve and also called the open rod gate valve.

Usually there is a trapezoidal thread on the lifting rod, which changes the rotary motion into linear motion through the nut at the top of the valve and the guide groove on the valve body, that is, the operating torque into operating thrust. When the valve is opened, when the ram lift height is equal to 1:1 times the valve diameter, the flow of the fluid is completely unobstructed, but this position cannot be monitored during operation.

In actual use, it is marked by the apex of the valve stem, that is, the position that cannot be opened, as its fully open position. In order to account for the lock-up phenomenon of temperature changes, it is usually rewound back to the apex position and then reverses 1 2 1 turns as the position of the fully open valve. Therefore, the fully open position of the valve is determined by the position of the ram, that is, the stroke.

Some gate valves, the stem nut is located on the gate, and the handwheel rotates to drive the valve stem to rotate, and the gate is lifted, this valve is called the rotary rod gate valve or the dark rod gate valve.

Through the transmission of the lead screw nut, the valve plate is driven to move up and down in a linear line to open and close the valve.

The gate valve is connected to the pipeline, when it needs to be closed, use your hand to twist or pull the valve handle runner above the gate valve clockwise, and the screw connected to the lower end of the runner will push the gate plate in the valve body down until the pipeline is completely blocked. If you want to open the valve, you need to turn the stem runner counterclockwise.

Understand the working principle of the gate valve in one minute.

Gate valve structure.

How the gate valve works:

The gate valve can only be fully opened or closed, and cannot be used as a valve to regulate the flow rate. Its working principle is that the ram plate rises and falls with the valve stem to do linear motion, and there is a trapezoidal thread on the valve stem, and the up and down movement of the valve stem is realized through the nut at the top of the valve and the guide groove on the valve body, and the valve stem drives the gate to move. The direction of movement of the ram is perpendicular to the direction of the fluid medium of the pipeline.
