Abstract

The invention provides an odorizing device for city gas. The odorizing device comprises a support. An alarm and a controller are fixed to a cross rod in the middle of the support, and the controller is located on the right side of the alarm. An odorizing agent barrel is a cylindrical bucket, an end cover sealed through threads is arranged at the top of the odorizing barrel, and an odorizing agentcan be added into the odorizing agent barrel after the end cover is opened. A through hole is formed in the right side of the end cover, and the hole is a threaded hole. A one-way valve is in sealed connection with the through hole of the end cover at the top of the odorizing agent barrel through a thread. An odorizing agent pipe is made from a transparent material, and connected to the right sideof the odorizing agent barrel through an upper pipe and a lower pipe, and the odorizing agent pipe communicates with the odorizing agent barrel. Pressure in the odorizing agent pipe is kept consistent with pressure in the odorizing agent barrel, and an odorizing agent at the same liquid level can be obtained. By arranging the one-way valve, when negative pressure in the odorizing agent barrel reaches the pressure value of the one-way valve, external air can enter the odorizing agent barrel to maintain the internal pressure, so that the pressure value in the odorizing agent barrel is larger than the air pressure value in an air conveying pipe all the time, and it is guaranteed that the pressure difference exists, and so that the oxidizing agent enters the air conveying pipe.

Description

technical field [0001] The invention belongs to the technical field of natural gas machinery, and more specifically relates to an odorizing device for urban natural gas. Background technique [0002] At present, a large number of urban households in my country use natural gas. Natural gas is a colorless, odorless gas. During the years of use throughout the country, numerous gas leakage accidents have occurred, causing varying degrees of loss to people's lives and property. Therefore, natural gas supply units all add odorant in natural gas as a warning agent for natural gas leakage. [0003] The Chinese patent with the application number CN201720817796.9 discloses an automatic odorizing device for monitoring natural gas leakage, including: an odorant supply mechanism, which includes an odorant storage tank, and odorizers in the odorant storage tank A heat exchanger for vaporizing the gasified odorant, a supercharger for pressurizing the gasified odorant, and an odorant buff...
