In order to solve the problem of above-mentioned proposition, the utility model design is a kind of with machinery, the electrical equipment transmitted power that is combined as a whole, and closes the device that the fuel gas source valve is a purpose to reach timing automatic.
The utility model is to realize with following technical proposal: it is made up of main wheel driving mechanism, timing control mechanism, transmission actuator and shell, its timing control mechanism is to be made of chip of LCD 8, battery 9, adjustment timing key 10, relay 11 and switch 15, and driving mechanism be by main shaft 6 and intermeshing transmission gear 1,2,2 ', 3 constitute, gear 1 is arranged on the main shaft 6, gear 2,2 ' coaxial connection, the gear 3 coaxial ratchets 4 that are provided with; Transmission actuator include the tooth sector 14 that is meshed with gear 1 and ratchet 4 match the ratchet connecting rod 12 that uses and with the gear 1 coaxial plane scroll spring that is connected 5, wherein the ratchet connecting rod is connected with tooth sector is coaxial; Shell is made up of loam cake 19, chassis 20.
One side of tooth sector 14 be provided with boss and and contact switch about in the of 15 the correspondence; The lower end of main shaft 6 is provided with the spliced eye that matches with gas cylinder valve rod profile; Be provided with the reset making leaf spring 16 of manual button 13 and connecting rod non-return ratchet 4 of ratchet connecting rod with ratchet connecting rod 12 corresponding positions on the shell.
The utility model from control source of the gas angle and design, be widely used on gas pipeline valve, the cylinder valves such as liquefied petroleum gas, coal gas, easy for installation, use flexibly, hold one's breath tight, regularly and economize gas, realization is closed the cylinder valve of combustible gas, the timing automatic of pipeline valve, to exempt the unnecessary worry of people
The utility model description of drawings:
Fig. 1 takes down plan view behind the loam cake for the utility model.
Fig. 2 is A-A sectional front view of Fig. 1.
Fig. 3 is that the B of Fig. 1 is to phantom.
Fig. 4 is the time control circuit schematic diagram.。
In conjunction with the accompanying drawings 1～4, overall structure of the present utility model and working principle thereof are described in detail:
Shown in Fig. 1～3: this timing closer is made up of main wheel driving mechanism, timing control mechanism, transmission actuator and shell, and wherein the timing control mechanism is made of chip of LCD 8, battery 9, adjustment timing key 10, relay 11 and switch 15; Driving mechanism be by main shaft 6 and intermeshing transmission gear 1,2,2 ', 3 constitute, gear 1 is installed on the main shaft 6, gear 2,2 ' coaxial connection, with gear 3 coaxial be connected a ratchet 4 arranged; Transmission actuator comprises the tooth sector 14 that is meshed with gear 1, with ratchet 4 match the ratchet connecting rod 12 that uses and with the gear 1 coaxial plane scroll spring that is connected 5, wherein ratchet connecting rod 12 and 14 coaxial connections of tooth sector, shell is made up of loam cake 19, chassis 20, see that from Fig. 2 main shaft 6 is the groundwork axle, its underpart and plane scroll spring 5 inside fix, its middle part is rigidly connected with gear 1, be provided with and the identical hole of gas cylinder valve (or pipeline valve) bar profile in its lower end, be used for and valve grafting location.The plane scroll spring periphery is provided with stop circle 7 and volute spring handing-over.Gear 2,2 ' coaxial, gear 3 are coaxial with ratchet 4, and two groups of gears and gear 1 mesh rotation simultaneously.Shown in Figure 1, one end of ratchet connecting rod 12 be arranged on electromagnet (relay) 11 near, its end that has ratchet matches with ratchet 4, its middle part is coaxial and sway separately with tooth sector 14, side at tooth sector is provided with boss, its effect: the one, touch power switch 15, two, blocking pawl connecting rod 12 falls.The shell of this timing closer is made of loam cake 19 and chassis 20, the dotted line that the making leaf spring 16 of each gear shown in the figure, rotating shaft, battery case, relay, chip of LCD, fixing clamp 18, fixed handle 17, ratchet connecting rod hand reset button 13 and connecting rod is installed on loam cake and the chassis upper end among Fig. 2 respectively by design attitude is represented the handwheel in the former steel cylinder, and the dotted portion of lower end is the suitable for reading and air outlet of former steel cylinder.
Regularly the working procedure and the state thereof of closer at first move the handwheel on the steel cylinder on closer main shaft 6, are connected as a single entity with steel cylinder on the valve rod of the hole of main shaft lower end insertion steel cylinder, fix fixing clamp 18 by handle 17.At this moment rotate counterclockwise handwheel (dotted line on Fig. 2 top) and promptly open cylinder valve, this moment gear 1,2,2 ' along with handwheel rotates counterclockwise, figure middle gear 1,2,2 ', 3 and tooth sector 14 does engagement simultaneously and rotates, but tooth sector 14 clockwise rotates.There is an end of boss to leave contact switch 15, power connection.Time control circuit is started working (timing), and ratchet connecting rod 12 is depressed by reed 16 simultaneously, makes ratchet 4 non-returns, and this moment, plane scroll spring 5 was in energy storage.Shown in Fig. 1,2,4: switch 15 closures, battery supply 9 power supplies, the time is adjusted timing button 10 (K on demand
