What is the working principle of the pneumatic submarine valve?

Subsea valve is a general term for all valves applied to underwater pipelines. At present, submarine valves are mainly used in underwater pipelines in underwater manifolds and transmission pipelines of offshore oil and gas projects. At the same time, underwater valves also have certain applications in deep-sea submersibles.

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.

How it works. The subsea valve adopts a single-acting cylinder structure, and the compressed air drives the piston rod to pull out. Open the spring of the middle plunger, open it, the medium passes, the work is completed, close the air source, the middle plug column relies on the spring, the reset seal, and close the valve.

In order to ensure that the valve has good working capacity, the following conditions must be met:

1. When the submarine valve is working, the pressure of the system air source must be guaranteed.

2 The valve body and the middle plunger must be highly sealed.

3 The spring must maintain sufficient elastic force to return.

3. Installation requirements.

1.When the submarine valve is installed on the tanker, it should be balanced with the tank. The gasket connected by the imported flange to the tank is a cork gasket provided by our factory, be careful not to damage it.

2.Pneumatic joints should be protected when installing air source hoses.

b) Use. The submarine valve has been debugged before leaving the factory, and can be used after installation, and shall not be disassembled at will.

Summary. Pneumatic subsea valves work by increasing pressure for control.

Pneumatic subsea valves work by increasing pressure for control.

What should I do if the pneumatic submarine valve can't be opened and the acid can't be discharged, thank you for being in a hurry.

The sausage is to increase his pressure and then open it to give it a try.

I've tried it all, but I can't open it, and the gas is normal. Good.

Summary. A marine subsea valve is a special solenoid switch that controls the water level and flow of a ship in order to provide effective ship management. Its main function is to control the water level of the ship when it enters the port, so that it can adapt to the water level of the port; When the ship leaves the port, the flow of the ship can be controlled to reduce the impact of waves in the port on the ship.

The marine subsea valve is a special solenoid switch that controls the water level and flow of the ship in order to provide effective ship management. Its main function is to control the buried water level of the ship when the ship enters the port, so that it can adapt to the water level of the port; When the ship leaves the port, the flow of the ship can be controlled to reduce the impact of waves in the port on the ship.

How is it on, how is it off.

The opening and closing of the submarine valve of the ship is generally realized by the operator through the Sun Han control system, and the specific operation steps are: 1First of all, the operator needs to open the control system of the submarine valve and enter the corresponding parameters; 2.

Then, according to the prompt, the operator clicks the open or close button, and the control system will open or close the submarine valve according to the operator's operation; 3.Finally, the operator needs to check the open or closed status of the subsea valve to be sure:

That direction is on, and that direction is off.

The opening and closing direction of the submarine valve of the ship usually refers to the opening and closing operation inside the valve, under normal circumstances, the clockwise direction is open, and the counterclockwise direction is off.

The water bottom valve is installed on the water surface at the water inlet of the water pump, the outlet of the valve is installed at the inlet of the water pump, and the inlet of the valve is directly connected to the water with a vertical pipe, which is installed vertically to stop the pump and stop the water, and the pump can be directly drained without water injection, replacing the original underwater bottom valve, and saving energy without blockage and leakage.

Each pump needs to be installed with a foot valve, the foot valve is usually installed underwater, and the SSDF 1 and JM3SSDF-2 water bottom valves are installed above the water surface, and their function is equivalent to a one-way check valve. The product is designed by the professional design institute of the Ministry of Railways, and the exclusive production of the patent bought out by our factory has passed the ministerial appraisal in eight five years, and won the Science and Technology Progress Award of the Ministry of Railways in six years. It is also included in the ninth volume of the "Manual for Careful Rent Planning of Water Supply and Drainage", and is widely used in power generation, pharmaceutical, chemical, textile, metallurgy, papermaking and other industries across the country.
