Abstract

The invention discloses a manual adjustment device for a natural gas boiler. The manual adjustment device for the natural gas boiler comprises a housing and a soft sealing core, wherein the housing comprises a cylindrical housing body; an 'L'-shaped locking groove is formed in the side wall of the housing body; the sealing core comprises a cylindrical core body; and a locking slot hole is formed in the side wall of the core body. According to the manual adjustment device, a temperature control knob can be restricted in the preset opening and prevented from being out of service by utilizing the 'L'-shaped locking groove in the housing and the locking slot hole in the sealing core body; natural gas is saved; and the manual adjustment device is simple and practical.

Description

technical field [0001] The invention relates to a natural gas equipment, more precisely, a manual adjustment device for a natural gas boiler. Background technique [0002] Natural gas boilers use natural gas to heat water to a certain temperature, and realize heating requirements and various industrial production needs through heating pipes and radiators. The temperature control knob of the existing gas-fired boiler does not have any limiting device, and workers can easily over-twist the knob and become ineffective, making the gas-fired boiler unusable. Contents of the invention [0003] The invention mainly solves the technical problems existing in the prior art, thereby providing a manual adjustment device for a natural gas boiler. [0004] Above-mentioned technical problem of the present invention is mainly solved by following technical scheme: [0005] A manual adjustment device for a natural gas boiler, the manual adjustment device for a natural gas boiler includes ...
