[0002] At present, the impregnating glue is used in the repair of shrinkage cavities and cracks in various fields. The impregnating glue is injected into the shrinkage cavity and cracks and waits for solidification. Therefore, the solidification parameter of the impregnating glue is the main standard for measuring the grade of the impregnating glue. In the process of chemical production of impregnating glue, samples of impregnating glue will be tested for solidification time and sealing after solidification. Continuous injection is required, and there are no pores. At present, impregnating glue is injected into holes of different sizes. , wait for solidification, observe the time and check the tightness. The existing injection method is to drop the colloid into the hole through the dropper, and then wait for the solidification. In the hole, the extrusion force is small, and it is difficult to squeeze the impregnating glue with neutral viscosity, and it is easy to stay in the mouth of the dropper, forming a blockage, affecting the injection speed of the impregnating glue, prone to delamination, and there are tiny pores, which affect Sealing, the existing needle tube is used for injection, but because the injection hole of the needle tube is small and the nozzle is exposed, it is easy to solidify into particles, and the particles will be injected into the small hole during injection, which will affect the detection of sealing
[0003] Publication number CN205165115U discloses a glue injector, comprising: a glue injection tube, the glue injection tube includes a rubber bag for containing glue, one end of the rubber bag is provided with a one-way valve, and the glue injector also includes a base seat, the base is provided with a glue injection hole, after the glue injection tube is installed on the base, the one-way valve is opened, the inner cavity of the rubber bag communicates with the glue injection hole, the The glue in the rubber bag flows out from the glue injection hole through the one-way valve. This device only injects the glue, and does not require the quality of the glue, and there is no requirement for exhaust sealing. It is not applicable Injection of chemical low viscosity impregnating glue

The invention provides a testing injection device for a chemical medium-viscosity impregnating adhesive and discloses a device for injecting the medium-viscosity impregnating adhesive through a built-in channel under matching of extruding exhaust. The device is characterized in that a partition board is arranged in a main cylinder, wherein one end of the partition board is connected with the innerwall of the main cylinder; a buffer channel and an adhesive injection channel are formed between the partition board and two sides of the main cylinder respectively; a communicating channel is formedbetween the other end of the partition board and the top of the main cylinder; the buffer channel and the adhesive injection channel are communicated through the communicating channel; one end of a guide sleeve is located at the bottom of the main cylinder and communicated with the adhesive injection channel, and diameter of the guide sleeve is gradually reduced from one end to the other end; a seal ring is arranged on the guide sleeve, and a rubber gasket is arranged on the surface of the seal ring; a heating plate is arranged on the guide sleeve and located on one side of the main cylinder;filter paper is arranged on the other side of the main cylinder and corresponds to the buffer channel; one end of an outer pipe is arranged at the other end of the guide sleeve and communicated withthe guide sleeve, and multiple external through holes are formed in the other end of the outer pipe.
Description
Technical field [0001] The invention relates to a chemical neutral viscosity impregnating glue inspection and injection device, which relates to a device for evacuating and injecting gas inside the impregnating glue during the inspection process of the neutral viscosity impregnating glue, and belongs to the field of chemical inspection. In particular, it relates to a device for injecting neutral viscosity impregnating glue through a built-in channel, cooperating with extrusion and exhaust. Background technique [0002] At present, impregnating glue is used in the repair of shrinkage holes and cracks in various fields. The impregnating glue is injected into shrinkage holes and cracks and waiting to be solidified. Therefore, the solidification parameters of the impregnating glue are the main criteria for measuring the grade of the impregnating glue. During the chemical production of impregnating glue, the impregnating glue will be sampled for the solidification time and sealing aft...
