優(yōu)質(zhì)進(jìn)口高溫止回閥品牌推薦德國洛克

一、進(jìn)口高溫止回閥結(jié)構(gòu)特點：

1、直通式，介質(zhì)流阻?。?/font>

2、維護(hù)及檢修方便、快捷。

3、閥門中口采用壓力自緊式密封結(jié)構(gòu)，介質(zhì)壓力越高，密封性能越好；

4、閥門開啟和關(guān)閉是靠介質(zhì)的作用力來實現(xiàn)的，介質(zhì)回流時自動快速關(guān)閉

5、密封面采用堆焊司太立鈷基硬質(zhì)合金，具有高硬度、抗腐蝕、抗氣蝕、優(yōu)良的抗擦傷性能，閥門使用壽命長；

1. Straight through type, small medium flow resistance;

2. Maintenance and repair are convenient and fast.

3. The middle port of the valve adopts the pressure self tightening sealing structure. The higher the medium pressure is, the better the sealing performance is;

4. The opening and closing of the valve are realized by the force of the medium, and the valve is automatically and quickly closed when the medium returns

5. The sealing surface is hardfacing Stellite cobalt base hard alloy, which has high hardness, corrosion resistance, cavitation resistance, excellent scratch resistance and long service life of the valve;

二、進(jìn)口高溫止回閥描述：

德國LOCKE洛克進(jìn)口高溫止回閥閥瓣與閥座密封面采用鈷基硬質(zhì)合金等離子噴焊而成，硬度高，抗沖蝕，經(jīng)久耐用，適用于公稱壓力PN1.6～42.0Mpa，工作溫度600℃的石油、化工、水力、火力電站等各種工況的管路上，切斷或接通介質(zhì)。適用介質(zhì)為：水、油品、蒸汽、及氣體、某些腐蝕性液體等。 

The sealing surface of the high temperature check valve disc and valve seat imported from Locke lock, Germany, is made of cobalt based carbide plasma spray welding. It has high hardness, erosion resistance and durability. It is suitable for the pipeline with nominal pressure of pn1.6-42.0mpa and working temperature of 600 ℃ in petroleum, chemical, hydraulic and thermal power stations, etc. to cut off or connect the medium. Applicable medium: water, oil, steam, gas, some corrosive liquid, etc.

三、進(jìn)口高溫止回閥應(yīng)用：

高溫止回閥適用于高溫液體或氣體管路，安裝在泵或風(fēng)機的出口處。它具有快速截斷管路介質(zhì)防止介質(zhì)逆流和保護(hù)泵或風(fēng)機不受損壞。該產(chǎn)品主要由閥體、閥桿、閥瓣、液壓緩沖裝置、氣動執(zhí)行裝置、傳動機構(gòu)、減壓裝置、電磁換向機構(gòu)、電路控制系統(tǒng)等部件構(gòu)造而成。此功能止目閥本廠有兩種外彤結(jié)構(gòu)供用戶選用，除此之外也可根據(jù)用戶要求來目來樣進(jìn)行設(shè)計制造。

High temperature check valve is suitable for high temperature liquid or gas pipeline, which is installed at the outlet of pump or fan. The utility model has the advantages of quickly cutting off the pipeline medium, preventing the medium from reverse flow and protecting the pump or fan from damage. The product is mainly composed of valve body, stem, disc, hydraulic buffer device, pneumatic actuator, transmission mechanism, pressure relief device, electromagnetic reversing mechanism, circuit control system and other components. This function check valve has two kinds of external structures for users to choose. In addition, it can also be designed and manufactured according to users' requirements.
