進口直埋式全焊接球閥德國洛克產(chǎn)品中心

進口直埋式全焊接球閥結(jié)構(gòu)特點：

1、直埋式全焊接球閥可以直埋于地下，無需建造高大閥門井，以減少工程造價，在此同時也可以避免操作閥門時造成人員的傷害。

2、直埋式全焊接球閥打開時，閥球把閥座完全包圍，盡管介質(zhì)有雜質(zhì)也沖刷不到閥座及球體密封面，由于這種特殊結(jié)構(gòu)使閥門密閉性與管道具有相同壽命。

3、關(guān)閉的直埋式焊接球閥介質(zhì)靜止對球體及密封閥座產(chǎn)生損害，打開的過程球體又把介質(zhì)靜止時沉積下來的雜物刮掉，閥座下有彈簧補償對壓力和溫度的變化有補償作用，保證不會產(chǎn)生任何泄露。

4、直埋式全焊接球閥可以直接焊于管道節(jié)省了法蘭、螺絲、墊片，節(jié)約大量物質(zhì)資源。

5、閥桿防飛結(jié)構(gòu)：在閥桿下部設(shè)置臺階，從閥體內(nèi)部下裝閥桿，防止閥桿飛出。

6、可根據(jù)管道的施工及設(shè)計要求，調(diào)整閥體的長短和閥桿的高度。

Structural features of imported 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. Anti flying structure of valve rod: steps are set at the lower part of the valve rod, and the valve rod is installed from inside the valve body to prevent the valve rod from flying out.

6. The length of valve body and the height of valve rod can be adjusted according to the construction and design requirements of pipeline.
