Abstract

The utility model discloses a gas solenoid valve, including valve body, iron core coil pack and sliding valve cover, install the sliding valve core that stretches into in the valve body in the lower extreme of sliding valve cover, the screw thread post is installed to the upper end, installs elastic buffer between screw thread post and the sliding valve core, and elastic buffer can effectively cushion the impact of sliding valve core and screw thread post, eliminates or reduces the impact between sliding valve core and the screw thread post, is favorable to reducing operational environment's noise pollution.

Description

A kind of gas solenoid valve

Technical field

This utility model relates to a kind of switch valve, particularly a kind of gas solenoid valve.

Background technology

Gas solenoid valve of the prior art does not has buffer structure between sliding spool and threaded post, and core-coil assembly leads to After electricity, in the moment of sliding spool adhesive, loud metal strike sound, this strike note meeting between sliding spool and threaded post, can be produced Bring noise pollution.

Summary of the invention

In order to overcome the deficiencies in the prior art, this utility model provides the gas solenoid valve that a kind of noise is little.

This utility model solves its technical problem and be the technical scheme is that

A kind of gas solenoid valve, including valve body, core-coil assembly and slide valve buckle, is provided with in the lower end of described slide valve buckle Stretching into the sliding spool in described valve body, upper end is provided with threaded post, is provided with elasticity between described threaded post and described sliding spool Bolster.

Described resilient snubber is rubber ring.

The upper end of described sliding spool is provided with the step post inside contracted, and the diameter of described step post is less than the described rubber ring heart Diameter, the height of described step post is less than the height of described rubber ring axial cross section.

Between described threaded post and described sliding spool, spring is installed.

The upper end end face of described sliding spool is provided with spring cavity, and the lower end of described spring is positioned in described spring cavity, upper end It is against on the lower end surface of described threaded post.

Between described slide valve buckle and described valve body, sealing ring is installed.

The outer wall of described slide valve buckle is provided with twice bulge loop, and the position between twice bulge loop forms annular groove, described close Seal is arranged in described annular groove.

The beneficial effects of the utility model are: be provided with elastic buffer between threaded post of the present utility model and sliding spool Part, resilient snubber can the impact force of effectively snubber slide spool and threaded post, eliminate or reduce between sliding spool and threaded post Strike note, advantageously reduce the noise pollution of working environment.

Accompanying drawing explanation

With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

With reference to Fig. 1, a kind of gas solenoid valve, including valve body 1, core-coil assembly 2 and slide valve buckle 3, described slide valve buckle 3 Being provided with the sliding spool 4 stretched in described valve body 1 in lower end, upper end is provided with threaded post 5, described slide valve buckle 3 and described valve body 1 Between sealing ring 8 is installed, the outer wall of described slide valve buckle 3 is provided with twice bulge loop 9, and position between twice bulge loop 9 forms ring Connected in star, described sealing ring 8 is arranged in described annular groove, and described valve body 1 is provided with fixed plate 12 by screw, described Fixed plate 12 pushes down the bulge loop 9 of upside, is fixed on described valve body 1 by described slide valve buckle 3, and core-coil assembly 2 is by installing Nut 13 in threaded post 5 is fixed on slide valve buckle 3.

Being provided with spring 10 between described threaded post 5 and described sliding spool 4, the upper end end face of described sliding spool 4 is provided with Spring cavity 11, the lower end of described spring 10 is positioned in described spring cavity 11, and upper end is against on the lower end surface of described threaded post 5, After core-coil assembly 2 power-off, sliding spool 4 resets under the elastic force of spring 10, seals the air flue in valve body 1.

Being provided with resilient snubber 6 between described threaded post 5 and described sliding spool 4, described resilient snubber 6 is rubber Circle, the upper end of described sliding spool 4 is provided with the step post 7 inside contracted, and the diameter of described step post 7 is less than the described rubber ring heart Diameter, the height of described step post 7 is less than the height of described rubber ring axial cross section, and the effect of step post 7 is to prevent rubber ring Excessive deformation and fragmentation, resilient snubber can effectively snubber slide spool and the impact force of threaded post, eliminate or reduce sliding spool And the strike note between threaded post, advantageously reduces the noise pollution of working environment.
