Abstract
A kind of anti-leakage gas switch.Gas range does not in the market cut out main valve, can not stop gas leak from source.The utility model composition comprises: device case (1), device case is connected with one group of heat expansion thimble housing (3) by installing stud (2), heat expansion thimble housing is built with heat expansion thimble (4) and adjusting nut (5), mounting nuts (6) is housed outside heat expansion thimble housing, one group of lever shaft seat (7) is equipped with in device case inside, by pivot pin (8) and primary lever (9) on one group of lever shaft seat, second lever (10), three grades of levers (11) connect, primary lever and second lever, second lever is all connected by connecting rod (12) with three grades of levers, pressing switch (13) is housed in the middle part of device case, jet (14) outside pressing switch and device case, coal gas main valve (15), power supply (16) is electrically connected respectively.The utility model is applied to the safe handling of coal gas.
Description
technical field:
the utility model relates to a kind of anti-leakage gas switch.
background technology:
though gas range in the market has flame-out protection device, the shortcoming of flame-out protection device to close coal gas main valve, so just can not avoid the generation of accident to leak the coal gas from source, makes the use of coal gas in daily life still dangerous hidden danger.
utility model content:
the purpose of this utility model is to provide a kind of anti-leakage gas switch.
above-mentioned object is realized by following technical scheme:
a kind of anti-leakage gas switch, its composition comprises: device case, the upper right side, top of described device case is connected with heat expansion thimble housing by installing stud with lower left side, described heat expansion thimble housing is built with heat expansion thimble and adjusting nut, outside described heat expansion thimble housing, mounting nuts is housed, one group of lever shaft seat is equipped with in described device case inside, by pivot pin and primary lever on lever shaft seat described in one group, second lever, three grades of levers connect, described primary lever and described second lever, described second lever is all connected by connecting rod with described three grades of levers, in the middle part of described device case, pressing switch is housed, jet outside described pressing switch and device case, coal gas main valve, power supply is electrically connected respectively.
described anti-leakage gas switch, described jet is connected with described power electric, and described coal gas main valve is connected with described power electric; Described device case is provided with pressing switch installing hole and one group of thimble stretches into hole, described heat expansion thimble housing is provided with heat conduction elongated hole and screw thread is installed, described primary lever, described second lever, described three grades of levers are provided with axis hole and connecting hole, one end that three grades of described levers coordinate with described pressing switch is provided with anti-tampering slope, described pressing switch is provided with to press and turns round.
the beneficial effects of the utility model:
1. the utility model is according to the principle of expanding with heat and contract with cold, pressing switch is in off-state when gas range cuts out, coal gas main valve is initially located in off-state, during use, first press jet, jet is connected rear coal gas main valve and is opened, point combusting range, cooking stove point then, heat expansion thimble expanded by heating extends, top is to primary lever one end, primary lever is rotated around lever shaft, the primary lever other end drives second lever to rotate, second lever drives again three grades of lever rotation, because the position of lever shaft seat is not in the centre of lever, the displacement that heat expansion thimble promotes primary lever is set to initial displacement, when being transferred to three grades of levers, the displacement that one end that three grades of levers coordinate with pressing switch produces is 50 times of initial displacement, pressing switch is closed, wherein initial displacement can be regulated by adjusting nut, when pressing switch closes, jet just disconnects automatically, and coal gas main valve is in opening under pressing switch closure state, after gas range is flame-out, heat expansion thimble cools, deformation is eliminated, lever playbacks, pressing switch disconnects, coal gas main valve cuts out thereupon.
the utility model is that the use of family gas stove provides safety guarantee, under the prerequisite that ensure that gas range normal usage function, make again coal gas main valve can the used time does not close automatically, gas range is allowed to use user to fasten coal gas main valve because forgetting and worry, this device only needs to press the normal use that a jet can ensure coal gas, convenient succinct, applicability is strong.
