進(jìn)口手動(dòng)截止閥認(rèn)準(zhǔn)德國(guó)洛克

進(jìn)口手動(dòng)截止閥結(jié)構(gòu)特點(diǎn)：

1、選材考究，符合DIN關(guān)標(biāo)準(zhǔn)，結(jié)構(gòu)合理，造型美觀。

2、閥瓣、閥座密封面采用鐵基合金堆焊或司太立(Stellite)鈷基硬質(zhì)合金堆焊而成，耐磨、耐高溫、耐腐蝕、抗擦傷性能好，使用壽命長(zhǎng)。

4、閥桿經(jīng)調(diào)質(zhì)及表面氮化處理，有良好的抗腐蝕性和抗擦傷性。

5、可采用各種配管法蘭標(biāo)準(zhǔn)及法蘭密封面型式，滿足各種工程需要及用戶要求。

6、閥體材料品種齊全，填料、墊片可根據(jù)實(shí)際工況或用戶要求合理選配，能適用于各種壓力、溫度及介質(zhì)工況。

7、倒密封采用螺紋連接密封座或本體堆焊奧氏體不銹鋼而成，密封可靠，更換填料可在不停機(jī)情況下進(jìn)行，方便快捷，不影響系統(tǒng)運(yùn)行。

進(jìn)口手動(dòng)截止閥工作原理：

截止閥一旦處于開啟狀態(tài)，它的閥座和閥瓣密封面之間就不再有接觸，因而它的密封面機(jī)械磨損較小，由于大部分截止閥的閥座和閥瓣比較容易修理或更換密封元件時(shí)無(wú)需把整個(gè)閥門從管線上拆下來(lái)，這對(duì)于閥門和管線焊接成一體的場(chǎng)合是很適用的。介質(zhì)通過(guò)此類閥門時(shí)的流動(dòng)方向發(fā)生了變化，因此截止閥的流動(dòng)阻力較高于其它閥門。

Working principle of imported manual stop valve:
Once the stop valve is in the open state, there will be no contact between the valve seat and the sealing surface of the valve disc, so the mechanical wear of the sealing surface is small. Because most of the valve seats and the valve disc are easy to repair or replace, it is not necessary to remove the whole valve from the pipeline when the sealing elements are replaced, which is very suitable for the occasions where the valve and the pipeline are welded together. When the medium passes through this kind of valve, the flow direction changes, so the flow resistance of the stop valve is higher than that of other valves.
                                                                               

進(jìn)口手動(dòng)截止閥產(chǎn)品簡(jiǎn)介：

德國(guó)洛克《DE LOCKE》進(jìn)口手動(dòng)截止閥也叫截門，是使用最廣泛的一種閥門，它之所以廣受歡迎，是由于開閉過(guò)程中密封面之間摩擦力小，比較耐用，開啟高度不大，制造容易，維修方便，不僅適用于中 低壓，而且適用于高壓。

Introduction to imported manual stop valve products:
The manual stop valve imported by German lock by Locke is also called the shut-off valve. It is the most widely used valve. It is popular because of the small friction between sealing surfaces, durability, small opening height, easy manufacture and convenient maintenance. It is not only suitable for medium and low pressure, but also suitable for high pressure.
