Detailed Description

The following description and the drawings sufficiently illustrate specific embodiments of the invention to enable those skilled in the art to practice them. Other embodiments may incorporate structural, logical, electrical, process, and other changes. The examples merely typify possible variations. Individual components and functions are optional unless explicitly required, and the sequence of operations may vary. Portions and features of some embodiments may be included in or substituted for those of others. The scope of embodiments of the invention encompasses the full ambit of the claims, as well as all available equivalents of the claims.

A block resistant vacuum evacuation system as shown in fig. 1 and 2, comprising: water tank 1, gravity drain pipe 2, its characterized in that still includes: the automatic water draining device comprises a tail end water draining system 3, a pneumatic control system 4, a vacuum station 5 and an air pressure stabilizing device 6, wherein the gravity water draining pipes 2 are located on two sides of the water tank 1, the tail end water draining system 3 is arranged above the water tank 1, the pneumatic control system 4 is connected with the tail end water draining system 3 through an air pipe, the vacuum station 5 is located on the right side of the tail end water draining system 3, and the air pressure stabilizing device 6 is located above the water tank 1. When the internal air pressure of the water tank 1 is insufficient after vacuum discharge and normal air pressure cannot be provided for next drainage, the air pressure stabilizing device 6 can provide stable air pressure for the water tank 1.

Further, the terminal drain system 3 includes: the vacuum interface valve 7 is positioned above the water tank 1, a drain pipe a8, a drain pipe b9 and a vacuum pipe 10 sequentially penetrate through the upper portion of the vacuum interface valve 7, the right side of the vacuum pipe 10 is connected with the vacuum station 5, the drain pipe a8 is vertically placed, and the drain pipe b9 is horizontally placed.
