進(jìn)口高壓止回閥德國洛克各種參數(shù)以及說明

一、進(jìn)口高壓止回閥特點：

1.產(chǎn)品設(shè)計制造按ANSIB16.34、E101標(biāo)準(zhǔn)，可與國產(chǎn)設(shè)備配備使用。

2.閥門中腔采用壓力自緊式密封結(jié)構(gòu)，內(nèi)腔壓力越高密封性能越好。支管兩端為3.支管兩端為對焊連接，適應(yīng)不同的接管要求。

4.閥門耐壓部件選用優(yōu)質(zhì)耐熱合金鋼制造，高溫性能好，承受壓力高，耐用、安全、可靠。

5.閥瓣、閥座的密封面采用司太立（stellite）鈷基硬質(zhì)合金堆焊而成，耐磨、耐高溫，抗擦傷性能好、使用壽命長。

6.閥瓣圍繞閥座外的銷軸旋轉(zhuǎn)，減少關(guān)閉時發(fā)生猛烈沖擊。

7.內(nèi)裝式的銷軸結(jié)構(gòu)，減小外泄漏點，使用更可靠。

1. The product is designed and manufactured in accordance with ansib16.34 and E101 standards, and can be used with domestic equipment.

2. The middle chamber of the valve adopts the pressure self tightening sealing structure, and the higher the inner chamber pressure, the better the sealing performance. The two ends of the branch pipe are 3. The two ends of the branch pipe are butt welded to meet different requirements of the connecting pipe.

4. The pressure parts of the valve are made of high-quality heat-resistant alloy steel with good high temperature performance, high pressure, durable, safe and reliable.

5. The sealing surface of valve disc and valve seat is made of Stellite cobalt based hardfacing, which is wear-resistant, high temperature resistant, abrasion resistant and long service life.

6. The disc rotates around the pin shaft outside the valve seat to reduce violent impact when closing.

7. The internal pin shaft structure can reduce the leakage point and make the use more reliable.

二、進(jìn)口高壓止回閥描述：

德國LOCKE洛克進(jìn)口高壓止回閥適用于兩種不同工況，一種是截介質(zhì)處于常溫，但是壓力很高，比如油田采油，注水。另一種是介質(zhì)處于高溫狀態(tài)，壓力亦高，比如熱電廠用的主蒸汽閥門。前者只考慮強度和高度就可以了，后者還應(yīng)考慮高溫下材料的強度和蠕變。

進(jìn)口焊接高壓止回閥主要用于高壓加壓的天然氣加氣系統(tǒng)，防止加壓天然氣倒流的閥門。焊接式高壓單向閥是靠管路中介質(zhì)本身的流動產(chǎn)生的力而自動開啟和關(guān)閉的，屬于一種自動閥門。焊接式高壓單向閥只允許介質(zhì)向一個方向流動，而且阻止方向流動。

The high pressure check valve imported from Locke lock in Germany is suitable for two different working conditions. One is that the cutting medium is at normal temperature, but the pressure is very high, such as oil field production and water injection. The other is that the medium is in high temperature state and the pressure is also high, such as the main steam valve used in thermal power plant. The former only considers the strength and height, while the latter also considers the strength and creep of materials at high temperature.

The imported welded high-pressure check valve is mainly used for the high-pressure natural gas filling system to prevent the backflow of pressurized natural gas. Welded high-pressure one-way valve is automatically opened and closed by the force generated by the flow of the pipeline medium itself, which belongs to an automatic valve. Welded high-pressure check valve only allows the medium to flow in one direction, and prevents the flow in one direction.
