This is the gate valve of the power station. z represents: gate valve 9 represents: electric.

Summary. It should be that the valve plate is bitten, the reason may be that a foreign object has been trapped between the valve plate and the valve housing, or it has not been rusted for a long time.

If the stem is a screw, you can try turning the handwheel with an extension rod. If you really can't do it, you have to remove the valve and check it.

What does the gate valve Z561Y model mean.

Gate valve Z561Y model, 5 is bevel gear transmission according to the provisions of the "JB T 308-2004 valve model preparation method of the world": Z== gate valve 5== drive mode: bevel gear 6== connection form:

Pick-up welded type 1== Structural form: Gangchun reversible single ram y== Sealing surface material: cemented carbide.

Thank you for your understanding. Now the valve can't be opened, the handwheel can easily rotate, but the ram and lead screw don't move!

What is the reason, please.

You know. It should be that the valve plate is bitten to death, and the original Huai waiter may have a foreign object sandwiched between the valve plate and Lu Ming's valve shell, or it has not been rusted for a long time. If the stem is a screw, you can try it with an extension rod to turn the handwheel.

If you really can't do it, you have to remove the valve and check it.

Summary. Possible causes: debris or poor meshing between the stem and the stem nut, separation of the stem and disc, corrosion of the stem and stem nut, excessive force on the disc and pressure of the packing material.

2) Treatment method: Lubricate the valve stem and valve stem nut frequently and remove debris; The valve stem is separated from the valve disc and should be disassembled and overhauled; When the disc is stressed too much, the valve is opened when the pressure is reduced.

What does the gate valve Z561Y model mean.

For you to inquire: z== gate valve 5== drive Dan opening mode: bevel gear 6== connection form: welded type 1== structural form: rigid Sun Yi single ram y== sealing surface material: hard clamping Kai Sui gold.

Now the valve can't be opened, and the handwheel opens easily, but the ram does not move.

Possible causes of original volt regression: debris or poor meshing between the stem and the stem nut, separation of the stem and disc, corrosion of the stem and stem nut, excessive force of the disc and packing pressure. (2) Solution:

Lubricate the stem and stem nut frequently and remove debris; The valve stem is separated from the valve disc and should be disassembled and overhauled; When the valve disc is stressed too much, the valve will be opened after the pressure is lowered.

PZ73Y Gate Valve Model Meaning refers to a specific type of gate valve. The specific meaning is as follows:

1.pz: indicates that the gate valve is a gate valve product, and according to the international standard naming convention, p stands for gate valve.

2.Z: This is a gate valve made of cast iron, and according to the international standard naming convention, Z stands for cast iron.

3.73: indicates that the nominal pressure of the gate valve is, according to the international standard naming rules, 73 means.

4.Y: It means that the sealing structure used by the gate valve is an elastic seal, and according to the first liquid rule of the international standard nomenclature convention, Y represents an elastic seal.

To sum up, the meaning of the PZ73Y gate valve model is a gate valve product with nominal pressure, made of cast iron, and elastic seal structure.

The selection and application of the PZ73Y gate valve model can be determined according to the specific engineering needs and working environment. According to different engineering requirements, different gate valve models and materials can be selected to ensure that the gate valve has good sealing performance, pressure resistance and corrosion resistance during the working process.

In addition, care should be taken to select the appropriate gate valve size and connection method to ensure compatibility with the piping system. In the process of installation and use, it is necessary to pay attention to maintenance, regularly check the sealing performance and operational flexibility of the gate valve, and deal with the failure or abnormal situation of the gate valve in time to ensure the normal operation of the gate valve and the safety of the project.

In short, the meaning of PZ73Y gate valve model is a gate valve product with specific pressure, material and sealing structure, and the appropriate model and application are selected according to actual needs to ensure the smooth progress of the project and the normal operation of the equipment.

An electric gate valve simply controls the valve with an electric actuator, which opens and closes the valve. It can be divided into two parts, the upper part is the electric actuator, the lower part is the valve action force distance is larger than the electric valve, the electric valve switch action speed can be adjusted, the structure is simple, easy to maintain, the action process is not easy to be damaged due to the buffer characteristics of the gas itself, but there must be a gas source, and its control system is also more complex than the electric valve. The electric gate valve is sensitive, safe and reliable, and many factories with high control requirements set up compressed air stations for pneumatic instrument control components.

The electric one is to be electric. and a device that can control its flow. The electric gate valve is widely used in petrochemical industry, thermal power plant and other oil products, water vapor pipelines as an opening and closing device for connecting or cutting off the medium in the pipeline.

Features: 1. Compact structure, reasonable design, good valve rigidity, smooth passage and small flow coefficient.

2. The sealing surface is made of stainless steel and cemented carbide, which has a long service life.

3. Flexible graphite filler is used, the sealing is reliable, and the operation is light and flexible.

4. The driving mode is manual, pneumatic, electric and gear transmission.

5. The structural form is elastic wedge single ram, rigid wedge single ram and double ram type.

Z94H-100 is a representative model of the back bar 100 refers to the pressure of 100 kg] reference.

This is a special electric gate valve for power stations, do you want to disassemble it?

z gate valve 9 electric 6 welded 2 runner y seal -0?

There are two standard forms of high-pressure gate valves for power stations, one is the introduction type that follows the JISL1E101 standard, and the other is the national standard type according to the JB3595 standard. The temperature-pressure levels they follow are consistent, and there is some interchangeability in some pipes. The middle part adopts the pressure self-tightening type without bonnet, which has good sealing performance under high temperature and high pressure conditions.

The self-sealing ring is made of two materials, one is mild steel and the other is flexible graphite 316 wire (mesh). The upper layer of the sealing surface is welded with drill-based cemented carbide, and the pure metal layer after processing is 3mm, which has wear resistance, high temperature resistance, corrosion resistance, scratch resistance and long service life. The two ends of the branch pipe are welded structures, and the welding groove can be made according to the standard or user requirements.

It is suitable for high-temperature and high-pressure water in thermal power plants, petrochemical industry, metallurgy, and metallurgical water, steam, oil, and superheated steam pipelines.

Product structure features:

The middle part is self-tightening without bonnet pressure.

2. The ram is a wedge-type elastic single ram or wedge-type double ram structure.

3. The gate seat is double-sided surfacing drill-based cemented carbide.

4. Anti-high temperature creep design.

5. The valve stem is made of nitriding precipitation hardening stainless steel.

6. There are manual, gear (bevel gear and spur gear) transmission, electric.

The wedge electric gate valve is a valve that operates in a straight line, which is matched with the Z-type multi-turn actuator, and there are on-off type and intelligent type. This type of valve is very simple to operate and is the most common type of open-close valve, which uses the up-and-down operation of the ram to turn on and off the fluid medium in the pipeline. It is widely used in chemical, papermaking, petroleum, electric power, metallurgy, sewage treatment and other sectors.
