高壓氣孔針閥安裝要注意什么?

高壓針閥一種耐壓高,通徑小的高壓截止閥。
High pressure needle valve is a high-pressure stop valve with high pressure resistance and small diameter.
1. 安裝高壓針閥前,檢查針閥外形有否損壞,若有損壞將可能導致針閥不能正常使用,此時可向技術人員或者供應商咨詢。
1. Before installing the high-pressure needle valve, check whether the appearance of the needle valve is damaged. If it is damaged, the needle valve may not work normally. At this time, consult the technician or supplier.
2. 安裝前,檢查閥接口、閥內部以及閥表面是否干凈,如果不干凈的話,可以用氣槍吹掃(注意:如果有鐵屑之類的,務必先將鐵屑等固體顆粒傾倒出來再吹掃,以免損傷閥體內部甚至密封面)。
2. Before installation, check whether the valve interface, the inside of the valve and the valve surface are clean. If they are not clean, they can be purged with an air gun (Note: if there are iron filings and the like, be sure to pour out the iron filings and other solid particles before purging, so as not to damage the inside of the valve body or even the sealing surface).
3.按照針閥結構,正確安裝針閥于管路或系統上。對于進出口有標識的針閥,按照標識(進口Inlet,出口Outlet)連接。對于進出口沒有標識的針閥,按照低進高出的原則連接,即處于低位的連接口是進口,處于高位的連接口是出口。注意管路和系統也須是清潔的,并且系統中應安裝有過濾器以保護系統元器件。
3. Correctly install the needle valve on the pipeline or system according to the needle valve structure. Needle valves with marks at the inlet and outlet shall be connected according to the marks (inlet inlet and outlet). For needle valves with no identification at the inlet and outlet, they shall be connected according to the principle of low inlet and high outlet, that is, the low connection port is the inlet and the high connection port is the outlet. Note that the pipeline and system must also be clean, and a filter shall be installed in the system to protect the system components.

4. 安裝完畢后,啟/閉針閥2-3次,以檢查其性能是否良好。注意,開啟或關閉閥門時,忌用力過猛(用力過猛可能造成造成密封失效)。通常,我們關閉閥門時,只要能關閉并耐住系統壓力即可,不能強蠻旋轉手柄。
4. After installation, open / close the needle valve 2-3 times to check whether its performance is good. Note: when opening or closing the valve, do not use excessive force (excessive force may cause seal failure). Usually, when we close the valve, as long as we can close and withstand the system pressure, we can't forcibly rotate the handle.
高壓針閥有以下特點:
High pressure needle valve has the following characteristics:
1.閥芯與閥體之間連接螺紋在密封墊片的后部,避免流體進入螺紋區,保證有好的外密封
1. The connecting thread between the valve core and the valve body is at the rear of the sealing gasket to avoid fluid entering the threaded area and ensure a good external seal
2.非旋轉閥芯(NRT Tip)結構,使得閥芯與閥體之間無旋轉磨損,閥芯與閥座僅存在上下運動,并保證每一次開關密封線位置不變,密封嚴密性強、閥門的壽命長。
2. The non rotating valve core (NRT tip) structure ensures that there is no rotating wear between the valve core and the valve body, the valve core and the valve seat only move up and down, and ensures that the position of the sealing line of each switch is unchanged, with strong sealing tightness and long service life of the valve.
3.專門的壓合密封墊螺母設計,使得外密封更可靠,無外泄漏。
3. The special compression gasket nut design makes the external seal more reliable without external leakage.
