Abstract
The utility model relates to a component of a gas meter, particularly an electromagnetic valve used by a gas meter. The electromagnetic valve is characterized in that the upper end of a pin shaft is provided with a slotted hole; one end of a small shaft is connected with a blocking cover, and the other end of the small shaft is connected with the slotted hole on the pin shaft via a shaft sleeve; the inner part of the slotted hole is provided with a cushioning spring; the upper end of a sealing sleeve is connected with the small shaft, and the lower end of the sealing sleeve is arranged between a casing and a sealing cover; the middle of the sealing sleeve presents a ripple shape. The utility model has the advantages of high working sensitivity, large upward and downward moving space of the small shaft, small gas resistance inside the sealing sleeve, favorable sealing performance, long service life, etc. The utility model can be used on an IC card gas meter.
Description
The utility model relates to the parts of gas meter, specifically a kind of solenoid valve of using of gas meter.
We know, gas meter extensively adopts IC-card to carry out toll administration now, employed solenoid valve is generally by upper shell on this gas meter, lower shell body, suction tude, the air outlet, blanking cover, bearing pin, the honey big envelope, the honey capping, copper sheathing, spring and skeleton, magnet steel, coil, lid, voltage-stabiliser tube, guide pillar, seat, adjust seat, packing ring, the honey seal, compositions such as adjusting screw, skeleton in the lower shell body, coil, copper sheathing, seat, bearing pin, magnet steel, voltage-stabiliser tube, spring and guide pillar etc. are formed the power unit of solenoid valve, adjust seat, packing ring and adjusting screw are used for the relative position of adjustment seat and bearing pin, the bearing pin upper end is provided with blanking cover, the blanking cover below is provided with stuffing box gland, the stuffing box gland upper end is connected with bearing pin, the stuffing box gland lower end is located between upper shell and the sealing cover, cylindrical or the taper type in stuffing box gland intermediate portion, the effect one of stuffing box gland is to prevent that coal gas from entering in the lower shell body, component are corroded, the 2nd, make bearing pin have certain on, following activity space, the working procedure of solenoid valve is; When outage, on the effect lower bearing pin of spring, move, make blanking cover block the air outlet, to reach the purpose of closing coal gas; When energising, move down at the effect lower bearing pin of electromagnetic force, the pulling blanking cover moves down, and opens the purpose that coal gas is ventilated to reach.The deficiency of this gas meter solenoid valve is that the sealing of blanking cover and air outlet is poor, working sensitivity is low, poor work stability, working life are short.
The purpose of this utility model just is to overcome the deficiencies in the prior art, and a kind of solenoid valve of a kind of working sensitivity height, good seal performance, long service life is provided.
For achieving the above object, the utility model can reach by following measure: a kind of solenoid valve, it is provided with upper shell, upper shell is provided with air outlet, suction tude, lower shell body, sealing cover, copper sheathing, skeleton, coil, lid, voltage-stabiliser tube, magnet steel, bearing pin, spring, guide pillar, seat, seal ring, adjustment seat, packing ring, adjusting screw, blanking cover, stuffing box gland, it is characterized in that the bearing pin upper end is provided with hole slot, little axle one end is connected with blanking cover, the other end warp beam sleeve is connected with the hole slot of bearing pin upper end, and the little axle in the hole slot is provided with damping spring.
The utility model has been owing to adopted said structure, when making it to have working sensitivity height, part time job impact force reduce, advantages such as long service life, good seal performance.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model, also is a kind of embodiment's structural representation.
Fig. 1 is a plan view of the present utility model.
Fig. 2 is the attached view of Fig. 1.
Mark among the figure: lower shell body 1, copper sheathing 2, coil 3, spring 4, skeleton 5, voltage-stabiliser tube 6, lid 7, magnet steel 8, sealing cover 9, suction tude 10, stuffing box gland 11, blanking cover 12, air outlet 13, upper shell 14, little axle 15, axle sleeve 16, damping spring 17, bearing pin 18, guide pillar 19, seat 20, seal ring 21, packing ring 22, adjustment seat 23, adjusting screw 24, lead-in wire 25, screw 26.
Below in conjunction with accompanying drawing the utility model is further described:
As shown in drawings: being provided with of the utility model upper shell 14 and the suction tude 10 that is provided with thereof, air outlet 13 is same as the prior art, and this does not give unnecessary details; The structure and the interconnected relationship thereof of lower shell body, skeleton 5, copper sheathing 2, coil 3, voltage-stabiliser tube 6, lid 7, magnet steel 8, sweet capping 9 and guide pillar 19, seat 20, seal ring 21, adjustment seat 23, adjusting screw 24 are same as the prior art, and this does not give unnecessary details; The top and bottom of bearing pin 18 are respectively equipped with slotted eye, the intermediate portion is provided with through hole, one of effect of through hole is to ventilate, bearing pin 18 cylindricals match with copper sheathing 2, bearing pin 18 can be along on the copper sheathing 2, move down, be provided with spring 4 in the slotted eye of bearing pin 18 lower ends, bearing pin 18 tops are provided with little axle 15, one end of little axle 15 is connected with blanking cover 12, the other end warp beam sleeve 16 is connected with the slotted eye of bearing pin 18 upper ends, in the slotted eye, little axle 15 is provided with damping spring 17, axle sleeve 16 and little axle 15 are for movingly, axle sleeve 16 is an interference fit with the slotted eye of bearing pin 18 upper ends, and the upper end of stuffing box gland 11 is connected with little axle 15, and it is stuck between little axle 15 two boss that are provided with or in the groove, the lower end of stuffing box gland 11 is located between upper shell 10 and the sealing cover 9, the intermediate portion of stuffing box gland 11 is corrugated, and upper shell 10 is connected by screw 26 with lower shell body 1, with fixing seal cover 11 and sealing cover 9.Working procedure of the present utility model is as follows: when outage, under the effect of spring 4, move on the bearing pin 18, drive on the little axle 15 and move, move air outlet 13, envelope position on the blanking cover 18, to reach the purpose of closing coal gas, because stuffing box gland 11 is corrugated, make little axle 15 that bigger up and down space be arranged, resistance of air reduces, the working sensitivity height, blanking cover 18 is good with the air outlet encapsulation; When energising, under the effect of electromagnetic force, bearing pin 18 at first moves down a segment distance, this moment, electromagnetic force was bigger, bearing pin 18 drives little axle 15, blanking cover 12 moves down, after certain distance is opened in blanking cover 12 and air outlet 13, under the effect of gas and damping spring 17, make blanking cover 12 get back to the enable possition, to reach the purpose of air feed, the utility model makes it to have the working sensitivity height owing to adopted said structure, and impact force reduces during component work, working stability, good seal performance, advantages such as long service life can be widely used in using on the IC-card gas meter.
