At this time, the external air pump is controlled to inflate the air inlet pipe 15, so that the air bags 3 can not be pressed down under the gravity action of the mounting ring 1 and the connecting ring 2 when being inflated, so that the two air bags 3 can be tightly attached to the inner wall of the heating pipeline after the inflation is completed, and the accuracy of the subsequent water injection test is further ensured.
After the two air bags 3 are inflated to be tightly attached to the inner wall of the heating and ventilation pipeline, the motor 11 is started to drive the rotating shaft 10 to start rotating, so that the moving column 27 starts to move circularly by taking the axis of the rotating shaft 10 as the center of a circle, and the moving frame 25 can move reciprocally in the horizontal direction, so that the piston cylinder 19 can move internally, an external water source can be conveyed into a closed space formed between the two air bags 3 and the connecting ring 2 through the water conveying pipe 12, the water pressure sensor 20 can transmit the water pressure in the closed space to an external controller in real time along with the water injection operation in the closed space, and an operator can judge whether the water tightness of the heating and ventilation pipeline reaches the standard or not only by observing the water pressure value displayed by the controller and whether water oozes out of the outer wall of the heating and ventilation pipeline; compared with the traditional two-end plugging of the heating and ventilation pipeline, the water injection pressurizing mode is carried out on the whole heating and ventilation pipeline outside the end, the water injection quantity is smaller, and the accurate test can be carried out on the joint of the two adjacent sections of heating and ventilation pipelines in a targeted manner, so that the operation is simple and convenient, the test effect is good, and the efficiency of the water tightness test of the heating and ventilation pipeline is improved.
Because the lower surface of carousel 9 has seted up the slope opening, under the effect of spring two 30 elastic potential energy, the rotation of carousel 9 then can make arc piece 40 carry out vertical ascending reciprocating motion, in order to make movable block two 24 drive movable disk 17 carry out the reciprocating motion of small distance, because the butt piece 7 of this moment has been with the inner wall butt of warm-way pipeline, the reciprocating motion of movable disk 17 at this moment, then can make movable block one 32 carry out reciprocating motion for butt piece 7, thereby can make the striking piece 38 of connecting rod 34 tip strike the inner wall of warm-way pipeline reciprocally, in order to make the warm-way pipeline shake, can be when carrying out the water injection to above-mentioned airtight space, when carrying out the water tightness test of warm-way pipeline, simulate when the water delivery in the warm-way pipeline is great, the condition when the impact of rivers to the inner wall of warm-way pipeline inner wall and the inner wall that makes adjacent two sections warm-way pipeline junction produced vibrations, the test range of warm-way pipeline of equipment to warm-way pipeline, can make the test result more accurate.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
