s7, open electronic air pump 15, electronic air pump 15 ventilates in to mount pad 11 through air duct 16, the accessible is attached in the state that detects the outside soap lye of casing 6, carry out short-term test to the gas tightness that detects casing 6, if it has the continuation bubble to check out the gas leakage point to detect outside certain department of casing 6, mark, simultaneously owing to install second connecting spring 25 in flexible brush 5 one end of smearing, flexible brush 5 of smearing can change according to the shape that detects the casing 6 outside and scribble, the degree of consistency and the validity of scribbling have been guaranteed.
The working principle is as follows: firstly, a detection shell 6 of water supply equipment needing to detect the sealing performance is installed, a positioning pin shaft 185 is pulled upwards directly through a pull ring 181, so that the positioning pin shaft 185 is separated from a positioning hole 20 in a base 9, at the moment, an installation seat 11 is automatically ejected out under the action of an outer ejection spring 14, the detection shell 6 of the water supply equipment is installed in the installation seat 11, after the installation, a second driving motor 7 is started, the second driving motor 7 can drive a driving gear 17 to rotate, the driving gear 17 can be effectively meshed with outer meshing teeth 23 of a sealing inner pad 12, so that the sealing inner pad 12 is driven to rotate rapidly, the sealing inner pad 12 can rub with the detection shell 6, and as a thermal expansion matrix 22 is filled in the sealing inner pad 12, heat can be generated during rubbing, the thermal expansion matrix 22 is heated to expand rapidly, so that the sealing inner pad 12 expands to be attached to the detection shell 6 more tightly, the tightness is kept, the liquid spraying pipe 2 is opened to spray the soap liquid in the liquid storage tank 19 to the telescopic smearing brush 5 through the liquid spraying pipe 2, the first driving motor 3 is started, the first driving motor 3 drives the installation turntable 4 to rotate, the installation turntable 4 drives the telescopic smearing brush 5 to rotate, the telescopic smearing brush 5 is made to rotate to evenly smear the soap liquid on the detection shell 6, the electric air pump 15 is started, the electric air pump 15 ventilates the installation seat 11 through the air duct 16, and the soap liquid can pass through the state of the soap liquid attached to the outer part of the detection shell 6, the air tightness of the detection shell 6 is rapidly detected, if a continuous bubble exists at a certain position outside the detection shell 6, an air leakage point can be detected and marked, meanwhile, as the second connecting spring 25 is arranged at one end of the telescopic smearing brush 5, the telescopic smearing brush 5 can be smeared according to the change of the shape of the outside of the detection shell 6, and the smearing uniformity and effectiveness are ensured.
It should be noted that: the outer side surface of the inner sealing pad 12 is made of hard plastic materials, so that the rotating effect after meshing connection with the driving gear is guaranteed, the inner side surface is made of soft rubber materials and can expand, the tightness of the fit of the inner sealing pad with the detection shell is guaranteed, and the thermal expansion matrix 22 is expanded graphite particles.
Because the rotation speed of the inner seal pad 12 is not high, the generated clockwise friction force is not large enough to reach the degree of abrasion of the inner seal pad 12, and the thermal expansion matrix 22 fills the gap between the inner seal pad 12 and the detection shell 6 after being heated and expanded, thereby realizing the sealing effect.
The mounting seat 11 is a hollow structure above the main body, when the detection shell 6 is mounted, the caliber of the detection shell 6 is consistent with the hollow area above the mounting seat 11, when the detection shell 6 is mounted, only the detection shell 6 needs to be directly clamped and embedded on the mounting seat 11, the detection shell 6 can be stably mounted on the mounting seat 11 due to the gravity of the detection shell 6 without being mounted by an external mounting structure,
the foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are given by way of illustration of the principles of the present invention, and that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims. The scope of the invention is defined by the appended claims and equivalents thereof.
