Abstract

The utility model provides a domestic natural gas leakage control and measurement device. The device consists of a probe 1, a hose 2, an air inlet valve sleeve 3, an air inlet valve ball 4, an air outlet valve ball 5, a cover 6, an oronasal mask 7, a pressing ring 8 and a soft cushion 9. When in use, the nose and mouth cover is used to cover the mouth and nose, the probe is placed near the detected part, the nose is used to slowly suck air, and the air leakage part can be quickly and accurately detected by means of olfaction.

Description

Domestic detector for natural gas leakage

The utility model is the instrument that can search the natural gas leakage rapidly that a kind of family uses.

Natural gas enters family and brings convenience to people life, and leakage phenomenon also can occur frequently simultaneously, sometimes even can be very serious.Cause that leakage factor is a lot, as joint poor sealing when new the installation, the pipeline part has defectives such as sand holes crack, and certain mating surface of kitchen range cooperates bad, air guide rubber hose coupling place cooperate sternly do not reach sebific duct service time long produce aging or the like.People enter and just know when the natural gas smell is smelt in the kitchen and leaked gas, but from where spilling, then easy-to-search not.Have human to smear the way of suds, it is coated in oneself thinks the position of gas leakage, this way is trouble, and can not all be coated with in all places, even be coated in the gas leakage position, also not necessarily just can blow afloat soap bubble.The somebody searches the gas leakage position with methods of printing, and that is breakneck way, and the accident that causes therefrom happens occasionally.

From existing books and periodicals and patent documentation are read, do not find structure similar and usage to the utility model.

The purpose of this utility model is to provide a kind of energy easy and promptly find out the instrument at gas leakage position, so that in time take measures, reduces the loss of natural gas and avoids the generation of serious accident.The method that this instrument is still with common nasil judges whether gas leakage, but it is the extension in people nostril, and is particularly more useful to searching the narrow positions that those nostrils can't arrive and crossing the leakage that exceeds the lower curtate position.

The accompanying drawing drawing is described as follows.

Among the figure: 1, detecting head; 2, flexible pipe; 3, air inlet valve pocket; 4, air inlet valve ball; 5, the valve ball of giving vent to anger; 6, lid; 7, oronasal mask; 8, trim ring; 9, cushion.

Below in conjunction with accompanying drawing usage of the present utility model is described.

Oronasal mask 7 is covered user's mouth and nose by the cushion 9 that is compressed by trim ring 8, hold detecting head 1 with one then and make its entrance point near leaking gas the position.The user is slowly air-breathing with the nostril, the valve ball of giving vent to anger this moment falls to blocking valve opening, the air inlet valve ball move to right and allow the position air of surveying stimulate sense of smell along detecting head 1, flexible pipe 2 inlet port nose cups 7, because gas leakage position natural gas concentration is inevitable greater than other position, thus according to smell promptly as can be known this place whether leak gas.During expiration, the air inlet valve ball moves to left and blocks valve opening, moves on the valve ball of giving vent to anger and makes valve open and allow gas discharge, and blocks ball and can not run away because of covering 6 herein.With this method everywhere search just can in short-term, find out gas leakage the position.

Realization of the present utility model is easy to, wherein flexible pipe 2, cushion 9, air inlet valve ball 4, the valve ball 5 equal buyables of giving vent to anger, and remaining parts is assembled into one then by injection molded.

Claims

1, a kind of family expenses natural gas leak detector, it is characterized in that: it is made up of parts such as detecting head, wireway, oronasal mask.During use oronasal mask is covered mouth and nose, detecting head place near the position of surveying, slowly air-breathing with nose, can find the gas leakage position by sense of smell.

2, family expenses natural gas leak detector as claimed in claim 1 is characterized in that: make the olfactory area of the gas of leakage position by pipe importing people with a kind of power, search the gas leakage position by sense of smell.
