Recommendation points



A positive feature of Soviet gas taps is their long service life and maintainability. However, such a valve requires regular maintenance, since the tightness of such a device is ensured by lapping the valve plug to the body, read more about this in our article.

The smell of gas in the area of ​​the plug valve is by no means a reason to replace it, but you still have to call a gas service representative to eliminate the cause of the leak.

This article describes step by step the process of revising two of the most popular gas cork cone taps: coupling and tension. Note that this article is not a call to action, but is offered solely for informational purposes, since gas hazardous work must be performed by specialized organizations that have the necessary permits. It will be useful to those who wish to personally verify the quality of the valve audit performed by the gas service.

Preparatory work

Before proceeding with the audit of the gas valve, it is necessary to find out whether the valve is really the source of the leak. To do this, wash the tap by applying foam to the connections. We find the places where gas passes to make sure that the valve is really the cause of the leak.

Note.The hose leading to the gas equipment was deliberately removed to show that a gas leak from the outside very often means a leak in the valve itself. Therefore, options to grease the case with grease on the outer surface, seal with clay and other folk methods do not completely solve the problem, but only create the illusion of safety.

There is no need to remove the gas valve from the pipeline to carry out an audit. In this article, this is done solely for clarity of the process. However, it is necessary to shut off the gas supply to the gas pipeline and release the pressure, as well as warn the neighbors to turn off all gas-consuming appliances.!

Required tool

To perform a revision, you need the following tool:

  • wide flat screwdriver
  • open-end wrench No. 17
  • gas valve grease
  • rags
