What conditions do you offer in exchange?

Please tell us about the specific on-site conditions.

The material of the valve body is determined according to the medium, the quality of the forging is better, there is no sand hole in the general forging, the density of the material is large, the cost is high, the casting has molded sand, sometimes the sand hole needs to be welded, in general, the forging and casting can be, only the material of the valve body is suitable for the medium, the wall thickness is guaranteed, there is generally no problem, like the ball valve, the material of the butterfly valve seat is determined according to the medium, such as acid resistance, high temperature resistance The selected materials are different.

There are many aspects to consider when choosing the material of the valve body, such as temperature: carbon steel can be used below 450 degrees, stainless steel can be used above 450 degrees, and high-temperature steel may be used for higher temperatures. Consider the cost as well;

Whether it is a casting or a forging, it depends on the complexity of the valve body structure, the manufacturability, the cost, and whether it is mass produced;

The seat material is generally related to the medium;

Refer to the valve design manual, which is very detailed;

Generally, it is processed in accordance with national standards, and sometimes according to customer requirements. The body material of the valve mainly depends on its use, such as used in chemical, petroleum, shipbuilding, natural gas, and other valves. The material should be determined according to its requirements and industry standards.

The same goes for the material of the seat.

The material of the main parts of the valve should first consider the physical properties (temperature, pressure) and chemical properties (corrosiveness) of the working medium. At the same time, it is important to know how clean the medium is (presence or absence of solid particles). In addition, it is necessary to refer to the relevant regulations and requirements of the state and the use department.

A wide range of materials can be used to meet the requirements of the valve in a variety of different working conditions. However, the correct and reasonable selection of the material of the valve can obtain the most economical service life and the best performance of the valve.

It should depend on his working conditions. The material of the valve body is selected according to the requirements of the working conditions. Every material has its own properties. Strength, elasticity. and so on.

Look at the "Valve Design Manual", which is very comprehensive.

Looks like you're trying to get involved in valve design? This kind of question is asked here, can you believe it?

To get started, it is recommended that you first take a look at the "Valve Design Manual".

Professional valve forum This ** is very good Go and see a lot about valves!

In general, it depends on what you do with it.

If the accuracy requirements are not high, buy two solenoid valves, control them with the same single switch, set up two manual ball valves after the solenoid valve, and adjust the flow rate by controlling the opening to roughly achieve the ratio relationship you require.

If the accuracy is high, you can directly go to the proportional control valve, which is commonly used in the hydraulic system, and you can ask the store that sells hydraulic components.

Using the principle of gear transmission, the gear drives the valve handle or hand lever to open and close the valve. Big gear: Small gear = 20:1

In fact, it is the screw that receives the ampere force, which can be judged according to the left-hand rule, which is found in high school physics.

Generally, it is provided by the design institute. If not, it is generally produced according to the standards of the current standard book.

Basically, they are all provided by design institutes.

It's simple, find a 10A meter. Voltmeter. A 3000w wire can be discharged by the ammeter wire in series, find the position required for the discharge current of the battery, and finally put the voltmeter battery on it.

Use a 500 watt electric stove or heating wire to connect the power consumption.

12V30W or 60W lamp cup, a few batteries are strung together with several lights for discharge.

Use an electric hot water stick However, the electric hot water stick should be soaked in water.

The rule of the left hand: In electromagnetism, the left hand is placed in the magnetic field, so that the magnetic inductance line penetrates vertically into the palm of the hand, the palm of the hand faces the n pole (fork in and out) version, and the four fingers point to the direction of the current right, then the direction of the thumb is the direction of the conductor force.

A simple description of the principle: the energized wire is continuously pushed by ampere force in the magnetic field provided by the magnet to produce rotational motion.

Change the direction of the magnetic field and the direction of the battery, and the wire will be reversed.

Not a concept, an electric valve refers to a valve with an electric actuator, an electric actuator is just an electric device that can be used on the valve, it includes a motor, a deceleration mechanism, a manual mechanism, a control mechanism, and so on.

No, the electric actuator is a component on the electric valve, he is the actuator of the electric valve. An electric valve is a combination of a valve and an electric actuator.

Not exactly a concept. An electric valve is a valve. The electric actuator is the motor and mechanical output mechanism that drives the valve. However, when referring to electric valves, electric actuators are often included.

An electric actuator is a starting device on a valve, while an electric valve is a combination of an electric actuator and a valve.

It's not a concept, it's divided into two parts.

The valve electric device is the driving device of the electric valve, which is used to control the opening and closing of the valve. DZW Z series multi-turn electric device is suitable for gate valves, globe valves, throttle valves, and diaphragm valves. It can be used for open stem valves and can also be used for dark stem valves.

It can accurately act according to the control command, and is an indispensable driving device for remote control, centralized control and automatic control of various valves and dampers.

The electric valve action torque is larger than that of ordinary valves, the electric valve opening and closing speed can be adjusted, the structure is simple, easy to maintain, and can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media.
