What are the advantages of directly buried welded ball valves and where are they used

Release date: June 4, 2020

Directly buried all welded ball valve Compared with ordinary valves, ordinary valves and pipelines need flanges, screws and gaskets. The connection between valves and pipelines wastes a lot of material resources, which is not conducive to the global environment and energy conservation and emission reduction. The directly buried all welded ball valve does not need flange, screw, gasket, and is connected with the pipeline in the form of welding. Good airtightness and simple operation.

Application of directly buried all welded ball valve:

City gas: gas export pipeline, trunk line and branch supply pipeline, etc.

Central heating: output pipeline, trunk line and branch line of large heating equipment.

Heat exchanger: opening and closing of pipes and circuits.

Iron and steel plant: all kinds of fluid pipeline, waste gas selective discharge pipeline, gas and heat supply pipeline, fuel supply pipeline.

All kinds of industrial gas pipeline and heat treatment equipment.

 Directly buried welded ball valve

Advantages of direct buried all welded ball valve:

1. The directly buried all welded ball valve can be directly buried in the ground, without the need to build a large valve well, so as to reduce the project cost, and at the same time, it can also avoid personal injury when operating the valve.

2. When the directly buried all welded ball valve is opened, the valve ball completely surrounds the valve seat. Although the medium has impurities, it can not wash the valve seat and the sealing surface of the ball. Because of this special structure, the valve tightness has the same service life as the pipeline.

3. The closed direct buried welded ball valve will damage the ball and the sealing valve seat when the medium is still. During the opening process, the ball will scrape off the foreign matters deposited when the medium is still. There is a spring compensation under the valve seat, which can compensate the change of pressure and temperature, so as to ensure no leakage.

4. The directly buried all welded ball valve can be directly welded to the pipeline, which saves flange, screw and gasket, and saves a lot of material resources.

5. Direct buried all welded ball valve is better than butterfly valve. When the butterfly plate flows in the middle medium, the debris in the medium will wash the butterfly plate, resulting in damage to the butterfly plate and make the valve not closed tightly;

6. Direct buried all welded ball valve is better than gate valve. In addition to the medium impurities, it washes the sealing surface, causing damage to the sealing surface and making it not tightly closed. When the medium is still, the debris in the medium will be accumulated in the valve gate groove, resulting in the gate not closing in place, so that the valve is not closed tightly.

6. It is light in weight, beautiful in appearance and easy to keep warm, which makes the appearance of matching equipment more exquisite.

7. Due to the special structure, the valve has a long service life and a 10-year warranty for normal use.
