阅读说明：本技术 永磁引流放大电空阀 (Permanent-magnet drainage amplifying electro-pneumatic valve ) 是由 钟芳顺 于 2019-10-08 设计创作，主要内容包括：电空阀的操控是用线圈、磁轭、衔铁组成,线圈通电产生磁场,吸合衔铁,用衔铁推动阀门。本发明是在衔铁位置改用鼓膜,用一个小小的线圈驱动小小的永磁体推动一组与阀座一样的微缩的上、下阀门,引出一股小小气流作用于鼓膜,用鼓膜推动阀门,完全替代了线圈,磁轭、衔铁功能；体积小,省料省电,彻底消除释放的脉冲过电压和剩磁危害,寿命延长百倍以上。(The electric pneumatic valve is controlled by a coil, a magnetic yoke and an armature, the coil is electrified to generate a magnetic field, the armature is attracted, and the valve is pushed by the armature. The invention changes the eardrum at the armature position, uses a small coil to drive a small permanent magnet to push a group of miniature upper and lower valves which are the same as the valve seat, leads out a small airflow to act on the eardrum, and uses the eardrum to push the valves, thereby completely replacing the functions of the coil, the magnet yoke and the armature; small volume, material and electricity saving, thoroughly eliminating the pulse overvoltage and residual magnetism hazards and prolonging the service life by more than one hundred times.)

1. A permanent magnetic drainage amplifying electro-pneumatic valve consists of a drainage part A and an amplifying part B, and is characterized in that an upper valve 9 of the amplifying part B is provided with a film-bulging chamber 11, a film plate 20 and a tympanic membrane support 10; the drainage part A drives a small permanent magnet to operate an upper valve A15 and a lower valve A19 to charge and discharge air to the tympanic membrane chamber 11 by using a small coil to get and lose electricity, and the upper valve 9 and the lower valve 4 of the amplifying part B are closed, opened and closed.

2. Claim 1 covers two-position three-way models and two-position two-way models.

3. The drainage part A and the amplification part B can be made into a one-piece type and a split type, the hidden channel 12 and the hidden channel A22 can be replaced by an open tube, and the one-piece type and the split type are covered by claim 1.

Technical Field

The present invention belongs to a control element for track traction pipeline

Background

The existing technique uses a large coil to control the armature to open and close the upper and lower valves, so as to achieve the goal of charging and discharging gas.

The invention content is as follows:

the valve in available technology is added with one film-blowing chamber to constitute one amplifying part, and one permanent magnet with small magnetic force line opposite to the small coil is used to open one group of miniature upper and lower valves and valve ports to constitute one drainage part. No residual magnetism harm, saving electric energy and prolonging the service life by more than one hundred times.
