Abstract

The utility model discloses a halogen gas leak detection device comprising a machine body, a probe and a connecting line, wherein the connecting line is connected between the probe and the machine body, the probe is provided with a cathode and an anode which are used for detecting halogen gases, the shell of the probe is composed of a pipeline and an air cavity located behind the pipeline, a filter screen is arranged at the pipe orifice of the pipeline, the cathode and the anode are located on the front end of the pipeline, an air outlet is formed in the side face of the air cavity, a foam board is arranged at the bottom of the air cavity, and a fan is arranged on the outer side of the air outlet. The halogen gas leak detection device has the advantages that the fan is located on the outer side of the probe, so that when at work, the fan can stably suck out air from the air cavity, and since the volume of the air cavity is large, after the air in the air cavity is sucked out, the pipeline can more quickly suck external air for the detection of the cathode and the anode, and thus, the measurement accuracy is effectively improved. The filter screen is arranged at the pipe orifice of the pipeline to prevent foreign matters from entering the pipeline to damage the cathode and the anode.

Description

A kind of halogen gas leakage detection apparatus
Technical field
The utility model relates to a kind of detecting instrument, especially a kind of halogen gas leakage detection apparatus.
Background technology
The manufacture maintenance of existing refrigeration, air-conditioning equipment and the halogen gas that is all widely used various chlorides and fluoride in fields such as chemical industry, pharmacy, medical treatment, as CFC, HCFC, HFC, R11 etc., these gases must be stored in the container of sealing, if occur, leak and not only can cause loss economically, also can work the mischief to environment.Whether halogen gas leak locator leaks for detection of these gases exactly.
Existing halogen gas leak locator, comprise body, probe and connecting line, described connecting line is connected between probe and body, in described probe, be provided with negative electrode and anode for detection of halogen gas, between negative electrode and anode, there is halogen gas through out-of-date, negative electrode and anode can discharge, thereby realize, detect.This halogen gas leak locator has a fan at probe, and it is inner that fan is positioned at probe, air draught weak effect, the accuracy that impact detects, a kind of probe scheme as disclosed in Chinese patent ZL99225504X just adopts.
Owing to there being such problem, so be necessary existing halogen gas leakage detection apparatus to improve.
Summary of the invention
The purpose of this utility model is a kind of fan air draught better effects if, the more accurate halogen gas leakage detection apparatus of measurement designing in order to solve the deficiency of above-mentioned technology.
The halogen gas leakage detection apparatus that the utility model is designed, comprise body, probe and connecting line, described connecting line is connected between probe and body, described probe is provided with for detection of the negative electrode of halogen gas and anode, its housing of described probe is that root pipeline and a wind chamber that is positioned at pipeline rear form by one, mouth of pipe place at pipeline is provided with screen pack, described negative electrode and anode are positioned at the front end of described pipeline, in side, wind chamber, be provided with air outlet, in bottom, wind chamber, be provided with cystosepiment, in described air outlet outside, be provided with fan.
As preferably:
Described negative electrode is cylindric, and the cross section of described anode is annular, and anode is positioned at negative electrode outside;
In described wind chamber, be provided with the timing device that a control fan rotates;
Described timing device is the time relay;
Described fan is embedded in the housing of described probe, in fan outside, is provided with protection network;
The halogen gas leakage detection apparatus that the utility model is designed, its beneficial effect is: fan is positioned at probe outside, can be by wind from stably sucking-off in wind chamber during work, because wind chamber volume is larger, therefore after the air in wind chamber is sucked away, pipeline can detect outside air intake more quickly for negative electrode and anode, thereby effectively improves measurement precision.Mouth of pipe place at pipeline is provided with screen pack, can prevent that foreign material from entering pipeline and damaging ring negative electrode and anode.
