In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
Example (b):
as shown in fig. 1, 2, 3, 4, 5, 6 and 7, a pneumatic distribution valve sealing structure includes:
the valve comprises a valve body 1, a main air channel 101 and a plurality of installation cavities 102 communicated with the main air channel 101 are arranged in the valve body 1, and an air inlet 103 communicated with the main air channel 101 and a plurality of air outlets 104 communicated with the installation cavities 102 one by one are further arranged on the valve body 1;
and the control parts 10 are used for controlling the on-off of air paths between the air outlets 104 and the main air channel 101, and one control part 10 is arranged in one mounting cavity 102.
Wherein the control member 10 comprises:
a coil former 2, one end of which is provided with an air tap 201, the air tap 201 is located in the installation cavity 102, the air tap 201 and the wall of the installation cavity 102 are sealed by a first O-ring 202 and a second O-ring 203 which are sleeved outside the air tap, a branched air passage 204 and a movable cavity 205 which are communicated with each other are arranged in the air tap 201, the branched air passage 204 is communicated with the main air passage 101, the wall of the movable cavity 205 is provided with an air vent 206 which is communicated with the air outlet 104, and the air vent 206 is located between the first O-ring 202 and the second O-ring 203;
