進(jìn)口低溫球閥德國洛克產(chǎn)品詳情參數(shù)尺寸圖片

一、進(jìn)口低溫球閥描述：

德國《LOCKE》洛克進(jìn)口低溫球閥(Low temperature valve)主要分為：低溫長桿球閥、低溫短軸球閥、低溫焊接球閥、低溫法蘭球閥、低溫螺紋球閥等。

允許根據(jù)客戶實(shí)際要求搭配不同閥軸長度、連接方式以及驅(qū)動(dòng)方式等。密封性能好，在超低溫工作時(shí)擁有優(yōu)良的理化性能。廣泛應(yīng)用于LNG系統(tǒng)、低溫液態(tài)氣體儲(chǔ)運(yùn)、制冷系統(tǒng)等。

The low temperature ball valve imported by Locke in Germany is mainly divided into: low temperature long rod ball valve, low temperature short shaft ball valve, low temperature welded ball valve, low temperature flange ball valve, low temperature threaded ball valve, etc.

It is allowed to match different valve shaft length, connection mode and driving mode according to the actual requirements of customers. It has good sealing performance and excellent physical and chemical properties at ultra-low temperature. It is widely used in LNG system, low temperature liquid gas storage and transportation, refrigeration system, etc.

三、進(jìn)口低溫球閥結(jié)構(gòu)優(yōu)點(diǎn)：

1、采用了在閥芯上開設(shè)減壓孔的構(gòu)造。

2、墊片是使用了含有具有穩(wěn)定密封性的陶瓷填充材料。

3、閥體輕、尺寸小。為了減少閥體的熱損失，特別是為了保證閥門超低溫下的使用，特意設(shè)計(jì)成重量輕、尺寸小的閥體。

4、長軸閥有低溫流體流經(jīng)的閥，采用長閥桿形式，可以避開外部熱的作用使壓蓋保持常溫，以防止蓋密封件的性能降低。此長度是通過計(jì)算、試驗(yàn)而得出的最佳長度。

1. The structure of opening a pressure reducing hole on the valve core is adopted.

2. The gasket is a ceramic filler material with stable sealing performance.

3. The valve body is light and small in size. In order to reduce the heat loss of the valve body, especially to ensure the use of the valve at ultra-low temperature, the valve body is specially designed to be light weight and small size.

4. The long shaft valve has a valve with low-temperature fluid flowing through, and adopts the long stem form, which can avoid the effect of external heat to keep the gland at normal temperature, so as to prevent the performance of the cover seal from decreasing. This length is the best length obtained by calculation and test.
