Problems solved by technology

[0004] 1. The packing and other components of the ammonia valve are exposed to the outside, and it is impossible to prevent the external liquid from flowing into or seeping into the cavity of the valve. The sealing performance is low, the service life is short, and if it is not replaced in time when it expires, the probability of leakage will increase and cannot be detected in time.
[0005] 2. After a certain period of ammonia leakage, the nose, throat, and eyes of the human body will be irritated, which may lead to blindness of the eyes, and the rainy weather will burn the human skin
There is no place to place the ammonia sensor, and the ammonia sensor cannot be exposed outdoors for a long time

Abstract

The invention provides an intelligent ammonia leakage control valve which can be provided with an ammonia sensor and can also sense ammonia leakage and reduce pollution to parts. An upper valve deck is located on a lower valve deck, and the bottom of the upper valve deck is fixed to the top of the lower valve deck. The lower valve deck is fixed to a valve body. A gland nut is arranged in a gland nut mounting hole. A valve rod nut is arranged in a valve rod nut mounting hole. A guide sleeve is arranged in a guide sleeve mounting hole. A filler gland is arranged in a filler gland mounting hole, and filler is arranged in a filler mounting hole. The intelligent ammonia leakage control valve further comprises an anti-explosion box and an ammonia sensor assembly. The ammonia sensor assembly comprises a control panel and the ammonia sensor which are connected. An ammonia sensor joint is arranged in the upper valve deck, communicates with the valve rod mounting hole and is located below the filler mounting hole. The ammonia sensor is installed in the ammonia sensor joint. The control panel is installed in the anti-explosion box, and the anti-explosion box is installed on the upper valve deck and covers the ammonia sensor.

Description

technical field [0001] The invention relates to an ammonia leakage intelligent control valve. Background technique [0002] Ammonia valves are widely used in the fields of controlling ammonia, ammonia liquid and gas, such as the Chinese patent application number 201610553111.0. [0003] The ammonia valve of the prior art has the following disadvantages: [0004] 1. The packing and other components of the ammonia valve are exposed to the outside, and it is impossible to prevent the external liquid from flowing into or seeping into the valve cavity. The sealing performance is low, the service life is short, and if it is not replaced in time when it expires, the probability of leakage will increase and cannot be detected in time. [0005] 2. After a certain period of ammonia leakage, the nose, pharynx, and eyes of people will be irritated, which may lead to blindness of the eyes, and the skin of the human body will be burned in rainy weather. At present, to monitor whether th...
