Abstract
The invention is a solenoid valve used in a gas meter. An upper shell is equipped with a gas inlet pipe and a gas outlet. Slots are arranged at the upper end and the lower end of a pin shaft respectively, and through-holes are arranged in the middle section. An external circle of the pin shaft is fit with a copper sleeve. The pin shaft moves upwards and downwards along the copper sleeve. A spring is arranged in the slot at the lower end of the pin shaft. A small shaft is arranged above the pin shaft. One end of the small shaft is connected with a plug cap, while the other end is connected with the slot at the upper end of the pin shaft. The small shaft in the slot is equipped with a buffering spring, and a shaft sleeve fits with the small shaft dynamically. The shaft sleeve fits with the slot at the upper end of the pin shaft in a way of interference. The upper end of a seal sleeve is connected with the small shaft, and the seal sleeve is clamped between two bosses arranged on the small shaft. The lower end of the seal sleeve is arranged between the upper shell and a seal cover. The middle section of the seal sleeve is corrugated. The upper shell and the lower shell are fixed together. The advantage of the invention is that the invention is provided with the high working sensitivity, the long usable life and good seal performance, and impact force to the parts is reduced at work.
Description
Technical field
The present invention relates to a kind of gas meter electromagnetic valve.
Background technique
At present, gas meter adopts IC-card to carry out toll administration, and the solenoid valve blanking cover of use is with the sealing of air outlet is poor, working sensitivity is low, work box is lacked qualitative poor, working life.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, a kind of gas meter electromagnetic valve is provided.
Technological scheme of the present invention is: a kind of gas meter electromagnetic valve is characterized in that: the bearing pin upper end is provided with hole slot, and little axle one end is connected with blanking cover, and 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 present invention has the following advantages: when working sensitivity height, part time job impact force reduce, long service life, good seal performance.
