Abstract
A switch controller for gas appliance is composed of timer, drive axle, cam, roller, plunger, valve body and spring, and features that when the timer is not working, the cam is at the top, the plunger is at the top under the action of spring force, the inlet and outlet of valve body are not communicated with the radial straight hole of plunger, when the timer is working, the cam is at the bottom, the plunger is at the bottom, and the inlet and outlet of valve body are communicated with the plunger.
Description
The utility model relates to the switch controlling device of combustion gas tool, particularly a kind of be contained on the combustion gas tool switch and with the safety shutdown devices of three interlocks.
Progressively raising along with living standards of the people, Gas appliance has been that cities and towns and part urban residents institute generally adopt, meanwhile, the problem safe in utilization of Gas appliance also causes people's great attention day by day, but still have quite a few user to lack necessary security consciousness at present, especially behind each use Gas appliance, all forgotten to close the total threshold switch on the fuel gas pipeline, cause great accident potential thus, bring serious threat for resident's the person and property safety.Building 4 104 Wang Jin great waves invention of bright western village, Nantong City, Jiangsu Province " the combustion gas tool reminds switch to set up music alarm circuit (patent No. ZL97236755.1) automatically; concrete structure is; the switch of stove and valve body are provided with tongue tube and are serially connected with music integrated circuit in the warning circuit; music integrated circuit is connected to battery; timer circuit and buzzer, Light-Emitting Diode.Basic functional principle is: after opening the fuel gas pipeline burnt gas switch, can normally use combustion gas, can normally open or close the burnt gas switch on the stove, this moment, warning circuit can not produce any actuation of an alarm, when burnt gas switch is all closed, and the fuel gas pipeline switch is not when being closed, and warning circuit will send warning will and warning passage of scintillation light, remind the user in time to close the fuel gas pipeline burnt gas switch.Owing to the fuel gas pipeline switch does not cut out under the situation that burnt gas switch is all closed and sends warning will and warning passage of scintillation light, therefore, at that time if under the situation about being absent from the scene, warning and warning passage of scintillation light do not produce effect to it, add and adopt the power supply of direct current as alarm and luminescent device, moment in opening and closing can produce bigger electric current, sometimes even can produce spark; Even under people's situation on the scene, the stopping using of short time, alarm also can be reported to the police, and causes interference so for a moment, and two can allow people be accustomed to, and can produce paralysis to later warning, and more some user feels very tired, and it is unfavorable that the safe handling of Gas appliance is brought.
The purpose of this utility model provide a kind of simple in structure, cost is low, and is safe and reliable, can in time close the combustion gas tool time switch of fuel gas pipeline switch.
The utility model is achieved in that a special service valve is set on fuel gas pipeline, top one timer of valve body, and timer is a mechanical type, and a timer and a power transmission shaft link, and the power transmission shaft lower end connects firmly disc cams, and disc cams contacts with the roller of plunger head.Plunger can pump in valve body, and the lower end of plunger has a through hole, and the hole wall of valve body also has corresponding hole.The lower end of valve body is provided with a spring, and an end of spring contacts the other end with the valve body bottom and contacts with plunger; When timer is inoperative, spring promotes that plunger moves up, valve body hole is not ganged up with consent firmly, gas cannot flow, after adjusting time switch, timer drives camming movement by power transmission shaft, and after entering the high edge of cam, plunger moves down gradually, thereby ganged up the string hole of valve body and plunger, gas can pass through.Because timer is mechanical type, the mutual motion of power transmission shaft, cam, plunger is mechanical movement, can not produce any spark, thereby be perfectly safe.
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing 1 is the structural representation of valve.
Valve body schematic diagram when accompanying drawing 2 is connection.
Accompanying drawing 3 is cam groove schematic diagrames.
In the accompanying drawing, the 1st, timer, the 2nd, power transmission shaft, the 3rd, cam, the 4th, roller, the 5th, plunger, the 6th, valve body, the 7th, spring, the 8th, the hole on the valve body, the 9th, the hole on the plunger, the 10th, the pit on the cam.
When timer is inoperative, spring (7) promotes plunger (5) and moves up, make hole (9) and the dislocation of the hole (8) on the valve body on the plunger, main body can not by valve body to two holes, when people need use the combustion gas tool, open time switch, and definite service time, timer (1) is started working, the transmission of power transmission shaft 2, driving cam (3) rotates, cam (3) contacts with roller (4), and makes the upper/lower positions of contact point board of cam (3) and roller (4), and the power that plunger (5) overcomes spring (7) moves down, hole (9) on the plunger is linked up with the hole (8) on the valve body, and gas can be by two holes between valve body; Variation along with timer (1) position, power transmission shaft (2) drives cam (3) and rotates, and until fixing time then, roller (4) is in the pit 10 on the cam, plunger (5) is by mobile on the power of spring 7, and the hole of closing on the valve body (6) (8) reaches the purpose of closing system-wide.The installation of timer can be decided according to the structure of combustion gas tool.
Claims (1)
- A kind of combustion gas tool switch controlling device, it is characterized in that having the valve body of turnover gas outlet and have the radially plunger composition valve idol part of straight hole, be provided with spring between the bottom of plunger and body cavity bottom, the upper end of plunger connects firmly a rotating roller, roller contacts with cam, the upper end and the power transmission shaft of cam link, and power transmission shaft can rotate around the direction of timer appointment.
