Abstract
The utility model discloses an inlet valve middle structure and relates to a gas engine component. The inlet valve middle structure comprises an inlet valve body. A stem of the inlet valve body is provided with three first circular grooves and a second circular groove. The inlet valve middle structure is simple in structure. The stem of the inlet valve body is provided with the circular grooves, a seal and a seal ring can be mounted at the grooves during assembly of an inlet valve with a gas valve guide tube, and accordingly tightness of the inlet valve is improved during use and oil and gas are prevented from leaking out of a gap between the gas valve guide tube and the inlet valve. The inlet valve middle structure is high in safety, high in energy utilization rate, and lower in unnecessary waste.
Description
Technical field
The utility model relates to a kind of gas engine assembly, is specifically related to a kind of intake valve central structure.
Background technique
The direct rod shape that present intake valve structurally generally adopts, this intake valve in use sealability is bad, causes the seepage of inflammable gas, and Security is low, has also caused the unnecessary waste of the energy, utilization ratio low simultaneously.
The model utility content
The model utility purpose: the utility model provides a kind of intake valve central structure in order to solve the deficiencies in the prior art.
Technological scheme: a kind of intake valve central structure, comprise the intake valve body, the bar section of described intake valve body from top to bottom is provided with first ring connected in star and the second annular groove.
As preferably, the number of described first ring connected in star is 3.
Beneficial effect: a kind of intake valve central structure described in the utility model, it is simple in structure, because section is provided with annular groove at this body rod of intake valve, when intake valve and the assembling of combustion gas door conduit seal ring and seal ring can be installed at the groove position, improved the sealability in the intake valve use engineering, stopped oil gas and in the gap of combustion gas door conduit and intake valve, oozed out, safe, energy utilization rate is high, has reduced unnecessary waste.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model specific embodiment is described in detail.
As shown in Figure 1, a kind of intake valve central structure comprises intake valve body 1, and the bar section of intake valve body 1 from top to bottom is provided with first ring connected in star 2 and the second annular groove 3; The number of first ring connected in star 2 is 3.
When intake valve body 1 and the assembling of combustion gas door conduit, be arranged with seal ring on the first ring connected in star 2, be arranged with O shape rubber seal on the second annular groove 3.
The above only is preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
