Abstract
The utility model introduces a water driven safety valve with an ignition lock; on the basis of an existing water driven safety valve, a membrane switch, or a small light touch switch, or a thin keyboard switch is arranged in the valve; a lead wire of the switch is separated from a wiring end of a coil. Because the size of the switch is small, the operating distance is very short, the structure of the valve is simplified, the size of the valve is shrunk, and the disadvantages of a microswitch of larger operating distance and inconsistent operation can be overcome; the water pressure for starting is reduced. The utility model has the conspicuous advantages of simple structure, easy fabrication, low cost, small size, high safety and large valve opening.
Description
The utility model relates to a kind of safety valve, particularly a kind of water-driven safety valve with ignition switch.
Existing water-driven safety valve does not generally have ignition switch.Unique water-driven valve that the band ignition switch that a family produces is arranged, its ignition switch is also independent, but with the shared tenminal block of magnetic core coil, also want adapted special ignition controller, so this valve body amasss bigger.
In view of the present situation that the water-driven safety valve exists, the purpose of this utility model is the water-driven valve that carries ignition switch in a kind of valve of design, with simplified structure, and reduced volume, convenient production and use.
For realizing above-mentioned purpose of design, the utility model has been taked following structure, it comprises magnetic core coil, magnetic sheet, axle, pull bar, spring, Sealing, shell and tenminal block, it is characterized in that having in the valve thin film switch or small-sized touch-switch or slight keyboard switch, this switch and magnetic core coil are connected as a single entity, and between switch and the housing spring-loaded are arranged.
Carry ignition switch in this valve; saved external igniting sensitive switch; because sensitive switch adopts thin film switch, its ignition switch operating distance is minimum, therefore; it is big not only to have overcome the sensitive switch operating distance; the inconsistent shortcoming of operating distance has reduced starting hydraulic pressure, has also simplified valve body structure simultaneously; having dwindled the volume of valve, is the safety valve of superior performance of functions such as realizing automatic control ignition, flame-out, blowout protection of matching with the pulse igniting controller in the aqueous vapor continuous action device.
Describe the utility model in detail below in conjunction with accompanying drawing:
Fig. 1 is this valve assembly structure schematic representation.
As seen from Figure 1, the water-driven safety valve of this band ignition switch is made of tenminal block 1, thin film switch 2, magnetic sheet 3, axle 4, spring 5,13, magnetic core 6, coil 7, seal ring 9,12, shell 8,10, sealing gasket 11, pad 14, push rod 15 and valve seat 16, magnetic sheet 3 is riveted together with axle 4, pad 14, sealing gasket 11 are through with axle 4, by housing 10 and spring 13 location, magnetic core 6, coil 7 connect as one by bonding or fastening piece with thin film switch, and spring 5 is supported between thin film switch and the housing.Seal ring 9 sealings are arranged between two-part shell 8,10, and seal ring 12 is used for location and the sealing between axle 10 valve shells.Thin film switch two terminal pins and winding wiring in the safety valve are independently of one another, are applicable to dissimilar ignition controlers, promptly can be used for the power cutoff positive pole, also can be used for the power cutoff negative pole.When being used for the power cutoff negative pole, minus earth can reduce by a tenminal block.
Originally the Water-driven safety valve that carries ignition switch has simple in structure, make easily, cost is low, volume is little, Operating voltage is low, the remarkable advantage that valve opening is big.
