Application |
|
1, J965Y station Y-type high-voltage globe valve with pressure seal from the tight structure, with a tight seal to contain the plates, the use of molding flexible graphite seal ring, the higher the pressure medium, seal the better the performance.
2, the use of percussive hand wheel to reduce the operating force.
3, embedded in valve seat, flat seal, valve and valve seat sealing surface are used cobalt-based alloy plasma spray made of wear-resistant, anti-abrasion, corrosion resistance of the stem surface by nitrogen treatment, media flow from the valve below.

产品外形及结构尺寸示意图

1, the appearance of ammonia and with the cut-off valve works.
The high-pressure chamber with the ammonia cylinder valve connection, low-pressure chamber for gas export, and access to use the system. Table showing the value of high-pressure storage of gas pressure within the cylinder. Low tables adjust screw outlet pressure can be controlled.
When you first open the cylinder using the master switch, then turn clockwise low pressure gauge pressure adjustment screw to compress the main spring and transmission film, pad and ejector spring the trap door open. This high-pressure gas imports from high-pressure chamber through the throttle decompression into the low pressure chamber and the exit leading to the work system. Turn the adjusting screw to change the valve opening height, thereby regulating the amount of high-pressure gas through the pressure to achieve the required value.
Ammonia valves are equipped with safety valve. It is to protect and make safe use of ammonia valve device, but also ammonia valve failure signal device. If, living doormat, valve damage, or due to other reasons, led to increased exports and more than a certain pressure on their own license value, the exhaust valve opens automatically.
Maintenance:
(1) Clean the valve: the general media for cleaning, wash with water as long as you can. However, the cleaning media is harmful to health, we must first understand its nature, and then choose the appropriate cleaning methods.
(2) the removal of ammonia with a valve: the exposed surface of the first rust rusty parts, but in the rust before, to protect the seat, plug, stem and putting other precision parts processing surfaces. Removable seat should use special tools.
(3) seat: there is a smaller sealing surface rust and wear, available machining methods, such as serious damage must be replaced. But regardless of repair or replacement of the seal surface must be ground.
