As further improvement of the utility model, the circular opening groove is coaxial with its through hole on the described sealing gasket, can guarantee that sealing gasket through hole lateral wall thickness is even.
As further improvement of the utility model, described sealing gasket upper shed fluted shaft is in the shape of the letter V to the cross section, guarantees that its root structure is more firm when can guarantee sealing gasket through hole lateral wall deformation behavior.
As further improvement of the utility model, through hole is a conical through-hole on the described sealing gasket, and its madial wall and open slot further guarantee fitting tightly of sealing gasket and gas pipeline group near the parallel sidewalls in axle center, guarantee its sealing property, and make things convenient for the assembling of gas pipeline group and sealing gasket.
As further improvement of the utility model, described sealing gasket can be dismantled the structure that seals in the open slot that is fixedly arranged on the combustion chamber: the sealing gasket axial side wall is provided with a circle inner groovy, perforate sidewall on the sidewall of combustion chamber be able to sealed card place in the inner groovy of sealing gasket, make things convenient for the installation of sealing gasket, and can guarantee the sealing of sealing gasket and combustion chamber.
As further improvement of the utility model, the perforate on the described sidewall of combustion chamber is the U type structure that a side is in communication with the outside, and sealing gasket also is the U type structure with combustion chamber hole shape coupling.
As further improvement of the utility model, the open side that is positioned at the U type on the described sealing gasket is provided with an otch that axially connects, this radial slot self sealss pad lateral wall extends in the through hole, makes things convenient for the gas pipeline assembling to join, and effectively utilizes the elasticity of gasket material to guarantee the incision sealing.
Useful technique effect of the present utility model is: the utility model is established the axial circular opening groove of a circle by the through hole radial outside that passes for the gas pipeline group on sealing gasket, make axial side of this through hole lateral wall and sealing gasket overall separation, when there is decentraction in the gas pipeline group with being connected of combustion chamber, the through hole lateral wall of sealing gasket guarantees to fit tightly with gas pipeline group lateral wall by distortion, guarantee the gas pipeline group of gas heater and the sealing and the stability of combustion chamber sealing structure, it is safer, more reliable that water heater is used.
