Abstract
The utility model discloses a gas protector, and particularly relates to a gas protector capable of preventing gas leakage, belonging to gas appliances. The gas protector comprises a gas inlet pipe, a gas outlet pipe and a knob, wherein the gas inlet pipe and the gas outlet pipe are arranged at two sides of the valve body, the gas protector is characterized in that a conical hole is arranged at the bottom of the valve body and is internally provided with a conical piston, the conical hole is connected with a buffer air chamber which is provided with a pressure spring, a gas protection chamber is arranged at one side of the upper part of the vavle body, the gas protection chamber and the conical hole are communicated by a bleeding pipe, the knob is connected with the conical piston through a shaft hole, an elastic rubber sheet is arranged at an outer opening of the gas protection chamber, a thread thimble is fixedly arranged at the center of the elastic rubber sheet, and the front end of the thread thimble is clamped on the thread of a knob rod. The gas protector has the beneficial effects that if only a switch before the stove is closed, due to self pressure of the gas, gas in the gas inlet pipe enters the gas protection chamber through the bleeding pipe so as to force the thread thimble outside the elastic rubber sheet to separate from the thread of the knob rod, the conical piston ascends under the action of the pressure spring so as to block off the gas inlet pipe and further prevent accidents due to gas leakage from occuring.
Description
Technical field
The utility model belongs to gas appliance, particularly a kind of gas protector that can prevent gas leakage.
Background technique
Usually reduction valve can not be realized the combustion gas protection when improper operation, the low inconvenient operation of remolding sensitivity.
The model utility content
Can not realize the deficiency of combustion gas protection in order to overcome existing reduction valve in improper when operation; the utility model provides a kind of gas protector; this gas protector not only has the characteristics of reduction valve, and can prevent gas leakage when improper operation, reduces the generation of accidental event.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of gas protector; comprise the turnover tracheae that is installed in the valve body both sides; be positioned at the knob at valve body center; it is characterized in that: the valve body bottom is provided with cone shape hole; tapered piston is housed in the cone shape hole; cone shape hole is connected with the buffer air chamber that pressure spring is housed; valve body top one side is provided with guarantor's air chamber; protect between air chamber and the cone shape hole and be communicated with by breathing pipe; knob is that axis hole is connected with the cone column piston; protect the air chamber collar extension elastic sheet rubber is housed; the elastic sheet rubber center is fixed wtih the screw thread thimble, and screw thread thimble front end is stuck on the screw thread of rotary knob rod.
The described tapered piston conical surface and central shaft angle are the 2-3 degree.
Described steam outlet pipe diameter is greater than suction tude diameter 3-8mm.
The beneficial effects of the utility model are, if only close kitchen range preceding switch gas-tank valve when not being closed, because the pressure of combustion gas self, coal gas in the suction tude enters guarantor's air chamber by breathing pipe, coal gas in protecting air chamber forces elastic sheet rubber external drum screw thread thimble to break away from the rotary knob rod screw thread when reaching certain pressure, the cone column piston rises under the effect of pressure spring suction tude is blocked, stop gas leakage to prevent contingency, the utility model is again a good reduction valve, its highly sensitive good airproof performance, time saving and energy saving, market potential is huge.
Description of drawings
Fig. 1 is structural representation of the present utility model,
Among the figure, 1. knob, 2. O-ring seal, 3. valve body, 4. cone column piston, 5. suction tude, 6. pressure spring, 7. buffer air chamber, 8. steam outlet pipe, 1 0. breathing pipes, 11. elastic sheet rubbers, 12. screw thread thimbles, 13. protect air chambers.
Embodiment
Embodiment of the present utility model is, as shown in the figure:
Embodiment 1, and a kind of gas protector comprises that the suction tude 5 that is installed in valve body 3 both sides, steam outlet pipe 8, steam outlet pipe diameter are greater than suction tude diameter 3-8mm.Between knob 1, valve body and the rotary knob rod at valve body center, O-ring seal 2 is housed, it is characterized in that: the valve body bottom is provided with is equipped with tapered piston 4 in cone shape hole, the cone shape hole, cone shape hole is connected with the buffer air chamber 7 that pressure spring 6 is housed, valve body top one side is provided with protects air chamber 13, protect between air chamber and the cone shape hole and be communicated with by breathing pipe 10, knob is that axis hole is connected with the cone column piston, protect the air chamber collar extension elastic sheet rubber 11 is housed, the elastic sheet rubber center is fixed wtih screw thread thimble 12, and screw thread thimble front end is stuck on the screw thread of rotary knob rod.The tapered piston conical surface and central shaft angle are the 2-3 degree.
