Abstract
The utility model belongs to a low-pressure small discharge gas switch, which includes a gas inlet, a gas outlet, a valve body, a bonnet, a knob arranged on the bonnet and a driven element of the knob. The utility model is characterized in that an integrative sealed rubber ring with a boss is arranged inside the valve body. The completely sealed rubber ring is fixed to the joint between the valve body and the bonnet. The driven element is made into a hollow body. The boss of the sealed rubber ring is mounted inside the hollow body of the bottom of the driven element. In addition, the sealed rubber ring and the driven element are connected with some bolts from the inner side of the driven element. The under part corresponding to the convexo platform of the sealed rubber ring is designed into a cone. The utility model has the following advantages: Since this structure is adopted, no metalwork is provided inside the gateway that directs to the gas inside the switch, which not only can avoid dysfunction of the switch due to the erosion of the metalwork, but also effectively improves the sealing property. The utility model can be used in the control valve for the gas-feeding gateway in the domestic gas utensils.
Description
Technical field
The utility model belongs to a kind of improved burnt gas switch, relates in particular to a kind of low pressure small flow burnt gas switch.
Background technique
Existing low pressure small flow burnt gas switch, its outlet passageway opens and closes by rotating cylindrical body or spheroid, is difficult to guarantee tightness when closure; The outlet passageway that also has be pressured go up and withdraw seal rubber pad open and close, for guaranteeing rubber cushion pressing and withdrawing and moving with drivening piece, need in switch rubber cushion contact combustion gas one side to guarantee that with screw or spring rubber cushion is close to drivening piece, but the hydrogen sulfide in the combustion gas will cause corrosion to screw or spring, if adopt anticorrosion screw or spring, then will increase cost.In addition, the existing low pressure small flow burnt gas switch that adopts rubber cushion to open and close outlet passageway, Shang Wuke are independently controlled the structural type of the two paths of giving vent to anger that open and close.
Summary of the invention
The purpose of this utility model provides a kind of low pressure small flow burnt gas switch of anticorrosion, good airproof performance.
Another purpose of the present utility model provides a kind of low pressure small flow burnt gas switch that can independently control two outlet passageways of switching.
The utility model is to realize like this, comprise suction port, air outlet, valve body, valve gap, be located at the knob on the valve gap and the drivening piece of knob bottom, it is characterized in that in valve body, being provided with the integral sealing rubber cushion of band boss, whole seal rubber pad is fixed in the joint of valve body and valve gap, drivening piece is made hollow body, the boss of seal rubber pad is installed in the hollow body of drivening piece bottom, and seal rubber pad and drivening piece is connected together with screw in the drivening piece inboard.The bottom of the double polarizing keys corresponding position of its seal rubber pad is designed to cone shape.
The novel main points of this reality also are to set up knob, drivening piece and an air outlet again on described switch, in valve body seal rubber pad on set up a boss, constitute two outlet passageway switches that two independent controls open and close.
The utility model has the advantages that: owing to adopted said structure, in switch, there is not metalwork in the path of contact combustion gas, the switching function Problem of Failure of not only having avoided the corrosion because of metalwork to cause, and improved sealability effectively, it is simple in structure, compact, be easy to make assembling, easy for operation, be suitable for use as the control valve of all kinds of household gas utensils air feed paths.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is the two outlet passageway structural representations of the utility model.
Embodiment
Below in conjunction with accompanying drawing to this reality and novel being described further.
Referring to accompanying drawing 1, comprise suction port 4, air outlet 1, valve body 5, valve gap 7, be located at the knob 9 on the valve gap and the drivening piece 8 of knob bottom, it is characterized in that in valve body, being provided with the integral sealing rubber cushion 6 of band boss, whole seal rubber pad 6 is fixed in the joint of valve body 5 and valve gap 7, drivening piece 8 is made hollow body, the boss of seal rubber pad 6 is installed in the hollow body of drivening piece 8 bottoms, and screw 3 is set in the drivening piece inboard, seal rubber pad 6 and drivening piece 8 are linked together, lean on screw rib-loop and boss and drivening piece endoporus stiction that seal rubber pad 6 and drivening piece 8 are fixed together like this.
The bottom of the boss corresponding position of seal rubber pad 6 of the present utility model is designed to thicker cone structure, and the tightness when making its shutoff air outlet is better.
Referring to accompanying drawing 2, a boss is set up in a novel threaded knob, drivening piece, the air outlet of having additional again on described switch of this reality on the seal rubber pad 6 in valve body 5, constitutes two outlet passageway switches that two independent controls open and close.When combustion gas is entered in the switch by gas-entered passageway 4,, control the output state of combustion gas from two outlet passageways 1 by rotating two independent knobs 9 respectively.When knob to backspin, rubber cushion is pressed on the air outlet this path of giving vent to anger of shutoff by drivening piece 8; When knob upwards revolves, previous compressed spring is upwards pressed drivening piece, makes it be close to the knob bottom, and drivening piece by screw and and the rubber cushion boss between stiction, rubber cushion is mentioned, allow this path of giving vent to anger outwards export combustion gas.
The utility model is simple in structure, compact, is easy to make assembling, and is easy for operation, is suitable for use as the control valve of all kinds of household gas utensils air feed paths.
