Abstract
The invention discloses a low return difference structure for a vertical rotor gas solenoid valve. A rubber sealing ring between an original rotor shaft and a valve shell is canceled, and the gas control return difference can be reduced exponentially, so that the gas quantity of the vertical rotor gas solenoid valve is accurately adjusted. Therefore, a leakproof cover is arranged between the periphery of a vertical rotor electromagnet and the valve shell, the rubber sealing ring is arranged between the leakproof cover and the valve shell, two wiring terminals are arranged to penetrate a side wall of the leakproof cover, insulating sealing rings are arranged between the wiring terminals and the side wall of the leakproof cover, and the two wiring terminals are electrically connected with a stator coil winding lead respectively.
Description
Technical field
The present invention relates to the gas electromagnetic valve technical field, particularly a kind of low return difference structure of vertical rotor type gas electromagnetic valve.
Background technique
The Chinese patent communique discloses a kind of " vertical rotor type gas electromagnetic valve ", its publication number is CN101493157A, should " vertical rotor type gas electromagnetic valve " have the saving material, advantage of simple structure, but since between its rotor shaft and the valve casing be adopt the seal ring sealing method gas sealing in valve casing, though it is simple in structure, but in order to guarantee not produce gas leakage after the long-term work, between seal ring and the rotor shaft enough magnitude of interference must be arranged, thereby seal ring can produce bigger frictional force and viscosity to rotor shaft, simultaneously, because seal ring is a rubber product, has rebound elasticity, thereby rotor just can produce bigger action displacement return difference when regulating back and forth, and its rotor return difference value is at 0.2 ° more than the angle, thereby occurs bigger return difference in the gas quantity adjustment process.This backlash phenomena are more apparent outstanding when little and gas quantity needs accurately to regulate in stator iron core material magnetic hysteresis.Therefore, when above-mentioned vertical rotor type gas electromagnetic valve will accurately be regulated gas quantity, just must solve the viscous problem that above-mentioned seal ring causes.
Summary of the invention
The object of the present invention is to provide a kind of low return difference structure of vertical rotor type solenoid valve, it does not have the rubber seal between rotor shaft and the valve casing, thereby just there is not elasticity viscous by rubber seal produced yet, can reduce combustion gas exponentially and regulate return difference, the gas quantity of vertical rotor type gas electromagnetic valve is regulated accurately.
Technical solution proposed by the invention is such: a kind of low return difference structure of vertical rotor type gas electromagnetic valve, comprise and being provided with into, the valve casing of air outlet and valve port, by stator iron core, the stator coil winding, the stator lateral plate, the upper rotor part fixed plate, rotor, the vertical rotor type electromagnet that rotor shaft and rotor controlling mechanism are formed, rotor shaft flexibly connects by bearing and valve casing, the axis hole of rotor shaft upper end portion and upper rotor part fixed plate flexibly connects, between described vertical rotor type electromagnet periphery and described valve casing, be provided with the leakproof cover, between leakproof cover and valve casing, rubber seal is housed, in the perforation of leakproof cover sidewall two tenminal blocks are housed, between tenminal block and the leakproof cover sidewall insulated enclosure circle is housed, two tenminal blocks are electrically connected with described stator coil winding leads respectively.
Compared with prior art, the present invention has following remarkable result:
(1) owing to the leakproof cover covers in the vertical rotor type electromagnet that comprises the rotor controlling mechanism that Regulation spring, adjusting nail, rotor adjusting screw, adjusting screw support are formed in it, again and rubber seal is housed between the valve casing, stator coil winding two lead-in wires of vertical rotor type electromagnet are electrically connected with two tenminal blocks that are contained in leakproof cover sidewall sealed insulation respectively, thereby not be used between rotor shaft and the valve casing seal ring is installed, just can guarantee that the combustion gas in the valve casing can be to the gas electromagnetic valve external leakage.Thereby thoroughly eliminated the gas leakage phenomenon that existing vertical rotor type gas electromagnetic valve causes because of fretting wear between rotor shaft and the seal ring.
(2) cancelled seal ring between rotor shaft and the valve casing after, the action displacement return difference problem of rotor, with regard to the caused adjusting return difference of magnetic hysteresis that only produces between remaining rotor and the stator iron core, select the soft magnetic material and the preferred heat treatment process of high-quality for use when rotor, stator, and its Magnetic flux density is controlled on the linearity range away from saturation point, the action displacement return difference of vertical rotor type electromagnet just can be controlled in 0.1 ° of angle.Because the action displacement return difference of vertical rotor type electromagnet reduces at double, the combustion gas of adopting the present invention to hang down the vertical rotor type gas valve of return difference structure is regulated can be more accurate, and governing speed can be faster.
