進(jìn)口低溫焊接球閥品牌廠家-德國洛克LOCKE-JQ4 

一、進(jìn)口低溫焊接球閥結(jié)構(gòu)特點(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 pressure reducing hole on valve core is adopted.

2. The gasket is made of ceramic filling material with stable sealing property.

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 with light weight and small size is specially designed.

4. The long shaft valve has a valve with low temperature fluid flowing through. It adopts the form of long stem, which can avoid the effect of external heat and 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 experiment.

三、進(jìn)口低溫焊接球閥產(chǎn)品簡介： 

德國洛克進(jìn)口低溫焊接球閥，也叫LNG焊接球閥，低溫不銹鋼焊接球閥，深冷低溫球閥，是指采用焊接的連接方式，指主要用于乙烯，液化天然氣裝置，天然氣LPG LNG儲(chǔ)罐，接受基地及衛(wèi)星站，空分設(shè)備，石油化工尾氣分離設(shè)備，液氧、液氮、液氬、二氧化碳低溫貯槽及槽車、變壓吸附制氧等裝置上，用來對(duì)低溫介質(zhì)進(jìn)行開啟和關(guān)閉的閥門。

 LOCKE低溫焊接球閥經(jīng)特殊的低溫處理，將粗加工的零件置于冷卻介質(zhì)中數(shù)小時(shí)（2-6小時(shí)），以釋放應(yīng)力，確保材料的低溫性能，保證精加工尺寸，以防閥門在低溫工況時(shí)，因溫度變化造成變形而導(dǎo)致的泄漏。閥門的裝配與普通閥門也不同，零件需經(jīng)過嚴(yán)格的清洗，除去任何油污，以保證使用性能。

Low temperature welding ball valve imported from Germany, also known as LNG welding ball valve, low temperature stainless steel welding ball valve and cryogenic low temperature ball valve, refers to the welding connection mode, which is mainly used for ethylene, liquefied natural gas device and natural gas LPG Valves used to open and close low temperature medium on LNG storage tank, receiving base and satellite station, air separation equipment, petrochemical tail gas separation equipment, low temperature storage tank of liquid oxygen, liquid nitrogen, liquid argon and carbon dioxide, tank car, pressure swing adsorption oxygen production device, etc.

After special low-temperature treatment, the rough machined parts are placed in the cooling medium for several hours (2-6 hours) to release the stress, ensure the low-temperature performance of the material, and ensure the finishing size, so as to prevent the leakage caused by the deformation caused by the temperature change in the low-temperature working condition of the valve. Valve assembly and ordinary valve is also different, parts need to be strictly cleaned to remove any oil, in order to ensure the use of performance.
