Abstract
The utility model discloses a three-ring-fire safety valve, which comprises a valve body integrally formed through cast. A gas channel is arranged in the valve body, a three-ring-fire pipeline communicated with a gas stove head is arranged on the valve body, and the three-ring-fire pipeline is communicated with the gas channel. A safety valve core is installed in the gas channel and is provided with a gas inlet hole communicated with the three-ring-fire pipeline. Rotating shafts enabling the safety valve core to rotate are installed in the safety valve core and in the gas channel and are connected with the safety valve core through a valve core pin, and the bottom of the valve core pin is contacted with a lever connected with a solenoid valve. The valve body is of an integral structure, and the flow direction of a gas source is reasonable. Gas enters from the air inlet, passes through a flame failure protection device, is controlled by the safety valve core, and flows to a stove from the air inlet hole. Therefore, the three-ring-fire safety valve is high in using safety and is widely applied to gas stove equipment.
Description
Technical field
The utility model relates to a kind of safety valve, a kind of especially three ring fire safety valves that are applied on the gas-fired boiler.
Background technique
At present, gas-fired boiler is equipped with the Safety control valve of control burnt gas switch and flow usually, in actual use; Docking between safety control valve body and the stove and accessory is to adopt independently to connect copper pipe, connects between copper pipe and the valve body through scyewed joint, and the mode of structure fabricating cost of independent copper pipe is high; In addition; Adopt Flow valve to control the flow of combustion gas, gas flow is unstable, influences firing effect.
Summary of the invention
In order to overcome the deficiency of existing function technology, the utility model provides a kind of stability of flow, the three ring fire safety valves that cost is low.
The utility model solves the technological scheme that its technical problem adopted:
A kind of three ring fire safety valves; Comprise valve body, be provided with blast tube in the described valve body, it is characterized in that the integrated casting of described valve body; Described valve body is provided with the three ring fire pipelines that are communicated with gas burner; Three ring fire pipelines communicate with blast tube, and safe spool is installed in the described blast tube, and safe spool is provided with the inlet hole that communicates with three ring fire pipelines; In described safe spool and the blast tube rotating shaft that can make safe valve core rotation is installed, rotating shaft connects with safe spool through the spool pin, and the bottom of spool pin contacts with lever, and lever connects with solenoid valve and flame-out automatic safety device.
The further design of the utility model: described three ring fire pipelines are divided into interior endless tube road, middle endless tube road and outer shroud pipeline, and the inlet hole on the said safe spool is three, and are communicated with three pipelines of three ring fire pipelines respectively.
The beneficial effect of the utility model is: the valve body of the utility model adopts integral structure, distributes the firm discharge combustion gas that is communicated with three ring fire pipelines through the safety spool, and gas flow is stable, and manual operation is simple, and is easy for installation, and fabricating cost is low; The source of the gas flow direction structure is reasonable, goes into gas from suction port earlier, arrives safe spool control again through flame-out automatic safety device; Arrive nozzle again and flow into stove and accessory, the flame-out automatic safety device that Safety valve body is installed can cut out source of the gas automatically in 25 seconds, guarantee the Security that the user uses; Avoid the generation of the accident of meeting accident, and Safety valve body uses 0 degree to start the solenoid valve assembling, directly opens flame-out automatic safety device; Need not Time Delay Opening, be widely used on the gas-fired boiler equipment.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is preferential embodiment's a split structural representation;
Fig. 2 is the structural representation of preferential embodiment's safe spool;
Fig. 3 is preferential embodiment's a safe spool cross-sectional view.
Embodiment
Referring to figs. 1 through Fig. 3, a kind of three ring fire safety valves, the preferential embodiment of the utility model comprises valve body 1; Be provided with blast tube in the described valve body 1; Described valve body 1 integrated casting, valve body 1 are provided with three ring fire pipelines, 8, the three ring fire pipelines 8 that are communicated with gas burner and communicate with blast tube; Safe spool 2 is installed in the described blast tube, and safe spool 2 is provided with the inlet hole 3 that communicates with three ring fire pipelines 8; The rotating shaft 4 that safe spool 2 is rotated is installed in described safe spool 2 and the blast tube, and rotating shaft 4 connects with safe spool 2 through spool pin 5, and the bottom of spool pin 5 contacts with lever 6, and lever 6 connects with solenoid valve 7 and flame-out automatic safety device.Described three ring fire pipelines 8 are divided into interior endless tube road 81, middle endless tube road 82 and outer shroud pipeline 83, and the inlet hole 3 on the said safe spool 2 is three, and are communicated with three pipelines of three ring fire pipelines 8 respectively.
The working procedure of the utility model: behind the air inlet source, rotating shaft 4 is depressed, and presses 4 to spool pin 5 through rotating shaft, and spool pin 5 is pressed onto lever 6, and lever 6 backs down solenoid valve 7.To unscrewing 90 when spending, three inlet holes 3 of safe spool 2 are maximum fire with the turnover gas through turn-knob, and to anticlockwise, a ring fire is put out gradually, is two sections firepower, rotate to left again in the time of can not turning, and be three sections firepower, promptly little fire.
The valve body 1 of the utility model adopts integral structure, distributes the firm discharge combustion gas that is communicated with three ring fire pipelines 8 through safety spool 2, and gas flow is stable, and manual operation is simple, and is easy for installation, and fabricating cost is low.The source of the gas flow direction structure is reasonable, goes into gas from suction port earlier, arrives safe spool 2 controls again through flame-out automatic safety device; Arrive inlet hole 3 again and flow into stove and accessory, the flame-out automatic safety device that Safety valve body 2 is installed can cut out source of the gas automatically in 25 seconds, guarantee the Security that the user uses; Avoid the generation of the accident of meeting accident, and Safety valve body uses 0 degree to start solenoid valve 8 assemblings, directly opens flame-out automatic safety device; Need not Time Delay Opening, be widely used on the gas-fired boiler equipment.
Combined accompanying drawing that the specific embodiment of the utility model has been carried out exemplary description above, obviously the utility model is not limited thereto, and the details of other not specified (NS) is also in the protection domain of the utility model.
