Abstract
The utility model discloses a check valve applied to a fireplace. The check valve is characterized by comprising a valve body in which a channel for gas to pass through is arranged. A valve core and a valve plug are arranged in the channel which is further provided with a spring capable of propping the valve plug and enabling the valve plug to seal a valve core vent. The spring props the valve plug and enables the valve plug to seal the valve core vent, so that the gas can only push the valve plug open from a gas inlet and pass through the channel. On the contrary, the gas entering from a gas outlet can not flow out through the gas inlet due to the fact the valve plug can only move in one direction. Accordingly, the function of the check valve is fulfilled. The check valve applied to the fireplace is simple in structure.
Description
[technical field]
The utility model relates to a kind of one-way valve that is applied to fireplace.
[background technique]
The fireplace that has now can use two kinds of sources of the gas, is provided with two source of the gas incoming ends in the bottom of fireplace, and wherein a kind of is rock gas, and a kind of in addition is exactly liquid gas, and this fireplace can make corresponding source of the gas according to user's needs.But, be not provided with one-way valve at the source of the gas incoming end of the bottom of fireplace, use like this and dangerous.
The one-way valve of the utility model designs to this kind situation patent.
[model utility content]
The utility model purpose is to have overcome deficiency of the prior art and a kind of one-way valve safe, easy to use, simple in structure is provided.
In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposal:
Be applied to the one-way valve of fireplace, it is characterized in that including valve body, in valve body, be provided with the passage that lets gas pass through, in passage, be provided with spool and valve plug, in passage, also be provided with and can valve plug withstood and makes valve plug seal the spring of spool pore.
The aforesaid one-way valve that is applied to fireplace is characterized in that said spool includes suction port and air outlet, and said air outlet is horn-like, and said valve plug passes through the spring roof pressure on the air outlet.
The aforesaid one-way valve that is applied to fireplace is characterized in that on said spool, being provided with outside thread, in passage, is provided with internal thread, and spool is threaded with passage, between spool and passage, is provided with O type circle.
The utility model compared with prior art has following advantage:
The utility model makes valve plug seal the spool pore because spring withstands valve plug, and gas can only pass through from passage after suction port is pushed valve plug open.Conversely, gas gets into from the air outlet, because valve plug can only move towards a direction, so gas can not flow out, realizes the function of one-way valve from suction port.There is the utility model simple in structure again.
[description of drawings]
Fig. 1 is the cut-away view of the utility model.
[embodiment]
Below in conjunction with accompanying drawing the utility model is described in detail:
As shown in the figure, be applied to the one-way valve of fireplace, include valve body 1, in valve body 1, be provided with the passage 2 that lets gas pass through.In passage 2, be provided with spool 3 and valve plug 4, in passage 2, also be provided with and can valve plug 4 withstood and makes valve plug 4 seal the spring 5 of spool 3 pores.
Specifically, said spool 3 includes suction port 31 and air outlet 32, and said air outlet 32 is horn-like, and said valve plug 4 passes through spring 5 roof pressures on air outlet 32.Because spring withstands valve plug, makes valve plug seal the spool pore, gas can only pass through from passage after suction port is pushed valve plug open.Conversely, gas gets into from the air outlet, because valve plug can only move towards a direction, so gas can not flow out, realizes the function of one-way valve from suction port.
As the optimal way of present embodiment, on said spool 3, be provided with outside thread, in passage 2, be provided with internal thread, spool 3 is threaded with passage 2, between spool 3 and passage 2, is provided with O type circle 6.
Like this, the bottom that the utility model is respectively installed to fireplace is provided with two source of the gas incoming ends, and when using rock gas, the another one source of the gas incoming end of fireplace is under the one-way valve effect, and rock gas can not overflow from this end.When using liquid gas, the another one source of the gas incoming end of fireplace is under the one-way valve effect, and liquid gas can not overflow from this end.
