Description
Technical field
The utility model belongs to valve technology field, relates to a kind of self closing stop valve, particularly a kind of gas self-closing valve.
Background technique
In recent years, combustion gas acted as a fuel and entered family more and more, and various household gas utensils also increase thereupon.Between gas range and gas pipeline, often directly connect, and such gas range often can not remove to cut off the main switch of gas pipeline again after being used to complete, thereby the accident that combustion gas leaks outside, poisons or explodes happens occasionally by pipe.
Summary of the invention
The purpose of this utility model is to have above-mentioned problem at prior art, and gas self-closing valve a kind of simple in structure, easy and simple to handle, safe in utilization is provided.
The purpose of this utility model can realize by following technical proposal: gas self-closing valve, be arranged between gas pipeline and the gas range, comprise valve body with suction port and air outlet, in valve body, has the cavity that communicates with suction port and air outlet, it is characterized in that, be provided with in the described cavity when the pressure of combustion gas in the cavity surpasses 1.5MPa and just can lean ball on the air outlet automatically, described ball employing rubber material is made.
The suction port of this gas self-closing valve is that the pipeline with combustion gas links, and the air outlet links with gas range.Under the normal state that uses, open gas range, combustion gas is come in by suction port, is gone out by the air outlet and enters into gas range.After gas range is used to complete, close gas range, like this pressure in the valve body of gas self-closing valve slowly reach 1.5MPa, at this moment, the ball that is in the cavity just can lean on the air outlet automatically, blocks the circulation of combustion gas, guarantees the safety of using.When opening gas range once more, pressure recovery is normal, leans at the ball on the air outlet can fall back to automatically under action of gravity in the cavity again, and suction port and air outlet are continued conducting again.And the ball of this gas self-closing valve adopts rubber material to make, and makes the sealability of ball when leaning on the air outlet better, need not to be provided with on the air outlet Sealing.
In above-mentioned gas self-closing valve, described valve body is provided with and can makes the ball that leans on the air outlet detach the resetting-mechanism of gas port.
In above-mentioned gas self-closing valve, described resetting-mechanism comprises bonnet, valve rod, is enclosed within valve rod outer connecting body and spring, connecting body is fixed on the valve body, above-mentioned valve rod and connecting body are slidingly connected, and cavity can be stretched in the inner of valve rod, and the outer end of valve rod passes connecting body and above-mentioned bonnet is connected, and is with spring outside valve rod, one end of described spring acts on the bonnet, and the other end acts on the connecting body.
When needing to use kitchen range once more, and ball does not fall back in the cavity automatically, can ball be carried out hand reset by this mechanism, and be arranged on in-house spring, and resetting-mechanism is resetted.
In above-mentioned gas self-closing valve, be provided with filter screen between the suction port of described valve body and the cavity.Filter screen can filter out other impurity in the combustion gas, prevents that impurity from stopping up this gas self-closing valve.
Compared with prior art, this combustion gas is self-closing has the following advantages:
1, is provided with the ball that to close the air outlet automatically, coefficient height simple in structure, easy to use, safe in the cavity in the valve body of this gas self-closing valve.
2, the ball of this gas self-closing valve adopts rubber material to make, and need not Sealing is set on the air outlet, makes the sealability of ball when leaning on the air outlet better, but also provides cost savings.
3, the valve body of this gas self-closing valve is provided with resetting-mechanism, and ball can be fallen back in the cavity smoothly, and is easy to use, simple.

Among the figure, 1, valve body; 2, suction port; 3, air outlet; 4, cavity; 5, ball; 6, valve rod; 7, bonnet; 8, spring; 9, connecting body; 10, filter screen.
Embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1, this gas self-closing valve, be arranged between gas pipeline and the gas range, comprise valve body 1 with suction port 2 and air outlet 3, in valve body 1, has the cavity 4 that communicates with suction port 2 and air outlet 3, be provided with in the described cavity 4 when the pressure of combustion gas in the cavity 4 surpasses 1.5MPa and just can lean ball 5 on air outlet 3 automatically, described ball 5 employing rubber materials are made.
Can make the ball 5 that leans on air outlet 3 detach the resetting-mechanism of gas port 3 being provided with on the valve body 1.Particularly, resetting-mechanism comprises bonnet 7, valve rod 6, is enclosed within connecting body 9 and spring 8 outside the valve rod 6, connecting body 9 is fixed on the valve body 1, above-mentioned valve rod 6 is slidingly connected with connecting body 9, and cavity 4 can be stretched in the inner of valve rod 6, and the outer end of valve rod 6 passes connecting body 9 and is connected with above-mentioned bonnet 7, is with spring 8 outside valve rod 6, one end of described spring 8 acts on the bonnet 7, and the other end acts on the connecting body 9.
When needing to use kitchen range once more, and ball 5 does not fall back in the cavity 4 automatically, can ball 5 be carried out hand reset by this mechanism, and be arranged on in-house spring 8, and resetting-mechanism is resetted.
Between the suction port 2 of valve body 1 and cavity 4, be provided with filter screen 10.Filter screen 10 can filter out other impurity in the combustion gas, prevents that impurity from stopping up this gas self-closing valve.
