Abstract
The utility model discloses a pressure adjustment device used for a gas burner. The pressure adjustment device used for the gas burner comprises an outer shell, a sealing cylinder body is arranged in the outer shell, a sealing rod is arranged in the sealing cylinder body, an adjustment valve strip is arranged on the tail portion of the sealing cylinder body, and a limit cylinder and a fastening nut are arranged on the head portion of the sealing cylinder body. The sealing rod in the sealing cylinder body is used, a cone-shaped sealing head is arranged at the front end of the sealing rod, and the sealing head is matched with the limit cylinder, so that sealing performance of the pressure adjustment device is greatly improved, and the pressure adjustment device used for the gas burner is especially suitable for pressure adjustment on the gas burner.
Description
Technical field
The utility model relates to a kind of natural gas equipment, more precisely, is a kind of regulator for natural gas combustor.
Background technique
Natural gas combustor is a kind of a kind of equipment that material is converted into heat energy by this chemical reaction mode of burning, and is about to air and fuel and converts so that it fully burns by proper proportion is mixed by pre-mixing apparatus, is mainly used in industrial production.Existing natural gas combustor, particularly high pressure burner, the sealability of its pressure regulator are still waiting to improve.
Summary of the invention
The utility model mainly is to solve the existing technical problem of prior art, thereby a kind of regulator for natural gas combustor is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of regulator for natural gas combustor, comprise a shell, be provided with a sealed cylinder in the described shell, be provided with a seal bar in the described sealed cylinder, the afterbody of described sealed cylinder is provided with a modulating valve bar, and the head of sealed cylinder is provided with a positioning cylinder and a tightening nut.
As preferred embodiment of the present utility model, described seal bar comprises a bar main body, the front end of described bar main body is provided with the sealing head of a taper, and described bar main body is provided with the position limit cycle of an annular, and the outer side wall of described position limit cycle is provided with a restriction protrusion.
As preferred embodiment of the present utility model, described positioning cylinder is that rubber is made.
Regulator for natural gas combustor of the present utility model utilizes the seal bar in the sealed cylinder, because the front end of seal bar is provided with the sealing head of a taper, by cooperating of sealing head and positioning cylinder, greatly improve the sealability of regulator, be particularly suitable for the pressure regulation on the natural gas combustor.
