Leakproofness；It is also cased with elastic protecting sleeve outside cylinder type tank body, elastic protecting sleeve can be used for shockproof.
Further, it is set on the sealing shroud there are four the L shape pressing plate for pushing down sealing shroud, each L shape pressing plate passes through spiral shell
Bolt is fixed.Sealing shroud is fixed by L shape pressing plate, so that it will not fall off.
Further, the junction of the elastic protecting sleeve and sealing shroud is fixed equipped with ring-shaped clip.Pass through annular snap
Fixing seal set is bound round, so that it will not fall off.
Further, the end cap is equipped with thermometer, and cylinder type tank body is protruded into thermometer test side.Thermometer is used for
Detect the temperature of cylinder type tank interior.
Further, pressure gage is additionally provided on the end cap, cylinder type tank body is protruded into pressure gage test side.Pressure gage is used
In the pressure of detection cylinder type tank interior.
The advantages of liquefied ammonia intermediate storage tank of this high leakproofness, has：
1. being connected with sealing shroud at the end cap of the holding vessel and cylinder type tank body, and sealing shroud inside air is evacuated and made
The sealing shroud is fitted in end cap and cylinder type tank body, further lift-off seal.
2. liquefied ammonia intermediate storage tank is exclusively used in reaching the storage of the high-purity ammon of 7N (99.99999%) standard, it is dedicated to full
The quality requirement of the industries such as sufficient photovoltaic, LED, OLED, liquid crystal display.
