The working principle is as follows: in the drainage process of the multi-air-retention blocker, when wastewater flows in through the liquid inlet 2-11 of the shell 2, the wastewater enters the liquid storage cavity 2-3 through a plurality of intersections between the lower water holes 5-1 of the sealing cover base 5 and the water permeable holes 4-1 of the sealing cover rotating body 4 (in the process, the sealing cover base 5 and the sealing cover rotating body 4 play roles of guiding and filtering large foreign matters), when the wastewater in the liquid storage cavity 2-3 enters the connecting body 7-1, a certain weight is formed after the water level reaches a certain height, the valve body 7-2 is opened by overcoming the elasticity of the pressure spring 7-4 under the action of gravity, and the wastewater flows out along the discharge channel (the opening of the valve body 7-2 is larger along with the higher water level and the larger water pressure).
In the process, the sealing switch pin 3-1 is driven to slide downwards by a human or an air cylinder, the sealing switch pin 3-1 drives the connecting rod 3-2 to slide downwards, the connecting rod 3-2 drives the cover rotating body 4 to rotate and slide (the rotating distance is determined by the stroke of the sealing switch pin 3-1, and the cover rotating body 4 rotates and slides around a boss on the cover base 5), so that the cover rotating body 4 and the cover base 5 rotate relatively, the originally separated water permeable hole 4-1 and the originally separated water drainage hole 5-1 are superposed to achieve the maximum water drainage effect, and the pin shaft plays a role in sliding and steering. When the drainage is finished, the sealing switch pin 3-1 is driven to slide upwards by a person or an air cylinder, the sealing switch pin 3-1 drives the connecting rod 3-2 to slide upwards through the shaft pin, the connecting rod 3-2 drives the cover rotating body 4 to rotate and slide through the shaft pin, so that the cover rotating body 4 and the cover base 5 rotate relatively, and the water permeable hole 4-1 and the water drainage hole 5-1 which are originally overlapped are separated to achieve a sealing effect.
When the multi-protection air blocker is used without water drainage, the valve body 7-2 is in a closed state under the elastic action of the pressure spring 7-4, and plays a good sealing role under the assistance of the PTFE pad 7-3, so that the phenomena of 'reverse water, reverse gas, reverse odor' and the like which are reflected by a sewer can be effectively isolated, and the part plays a first protection role of the multi-protection air blocker. When the valve body 7-2 or related parts cannot play an effective blocking role due to aging or other reasons, a small amount of gas leaks into the liquid storage cavity 2-3, a liquid sealing surface is formed in the liquid storage cavity 2-3 by the sleeve 5-2 of the sealing cover base 5, so that the gas can be effectively prevented from passing through, the part plays a second protection role of the multi-air-protection blocking device, and the part can also provide disinfectant for the multi-air-protection blocking device through the liquid sealing inlet 1-1 formed in the sealing cover 1 so as to achieve the effects of blocking the liquid seal and sterilizing.
The protection effect of the multi-protection air blocker can effectively block the phenomena of 'water return, gas return, odor return' and the like of a sewer, wherein the first protection mainly plays a role in blocking 'water return, gas return and odor return', the second protection mainly plays a role in blocking 'gas return, odor return and sterilization' after the first protection is aged, and the third protection mainly plays a role in blocking 'water return, gas return, odor return, water discharge regulation and filtration'.
The air blocking device is protected more can be designed as lower drainage type, left drainage type, right drainage type according to the demand, also can carry out the corresponding change of size according to the difference of connecting line.
The multi-protection air blocker can be connected with a floor drain for use, can be connected with a pipeline for use, and can be buried underground for use.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
