二、進(jìn)口低溫絲扣止回閥結(jié)構(gòu)特點(diǎn)： 

1、流體阻力小，密封面受介質(zhì)的沖刷和侵蝕小。

2、其防水錘性能好，結(jié)構(gòu)簡單，成本低

3、介質(zhì)流向受限制，只允許介質(zhì)向一個方向流動。

4、形體簡單，結(jié)構(gòu)長度短，制造工藝性好，適用范圍廣。

5、流道通暢、流體阻力小

6、動作靈敏、密封性能好

7、閥瓣行程短、關(guān)閥沖擊力小

8、整體結(jié)構(gòu)、簡單緊湊、造型美觀

9、使用壽命長、可靠性高

1. The fluid resistance is small, and the sealing surface is less eroded and eroded by the medium.

2. The hammer has good performance, simple structure and low cost

3. The flow direction of the medium is limited and only one direction is allowed to flow.

4. The utility model has the advantages of simple shape, short structure length, good manufacturing technology and wide application range.

5. The flow channel is unobstructed and the fluid resistance is small

6. Sensitive action, good sealing performance

7. The valve disc stroke is short and the impact force of valve closing is small

8. Overall structure, simple and compact, beautiful shape

9. Long service life and high reliability

三、進(jìn)口低溫絲扣止回閥產(chǎn)品簡介：

德國LOCKE洛克進(jìn)口低溫絲扣止回閥又稱低溫逆止閥、低溫單向閥、低溫逆流閥、和低溫背壓閥，是指采用螺紋的連接方式，在低溫貯槽上或者低溫管道系統(tǒng)，依靠介質(zhì)本身流動而自動開、閉閥瓣，防止低溫介質(zhì)液氧，液氮，液氬，液化天然氣，LO2、LN2、LAR、LNG等倒流的閥門，

LOCKE低溫止回閥結(jié)構(gòu)緊湊、體積小、重量輕，防止倒流零泄露，穩(wěn)定性好。

The low temperature screw thread check valve imported from Germany Locke, also known as low temperature check valve, low temperature one-way valve, low temperature reverse flow valve and low-temperature back pressure valve, refers to the use of threaded connection, in the low-temperature storage tank or low-temperature pipeline system, depending on the flow of the medium itself to automatically open and close the valve disc, to prevent low-temperature medium liquid oxygen, liquid nitrogen, liquid argon, liquefied natural gas, LO2, LN2, LAR, LNG, etc Flow valve,

Locke low temperature check valve has the advantages of compact structure, small volume, light weight, preventing backflow and zero leakage and good stability.
