[0003] However, the prior art has the following defects:

[0004] However, the sampling hose of the sampling equipment has a simple structure and limited corrosion resistance. When sampling in radioactive waste liquid, the hose is prone to aging and has a poor service life. Bumps and impacts during the sampling process can cause the sampling tube to deform and break or loosen the connection with the sampling equipment, resulting in poor sealing performance and easy leakage of sampled materials. Utility Model Content

[0005] The purpose of the utility model is to provide a corrosion-resistant sampling hose with an improved structure to solve the problems raised in the above background technology.

[0011] By adopting the above technical solution, the second anti-slip sheet can tightly connect the sampling tube opening and the second connecting tube opening, prevent loosening, ensure sealing, and avoid sample leakage.

[0012] The first connecting pipe mouth includes a connecting piece, and a flange is fixedly installed on the outside of the hose body away from the sampling pipe mouth. The middle part of the flange and the middle part of the connecting piece are connected through a connecting pipe.

[0015] By adopting the above technical solution, the first anti-slip sheet is clamped between the first connecting pipe opening and the sampling device connecting opening, thereby reinforcing the connection between the two, preventing slipping and loosening, and improving the sealing performance.

[0016] A number of reinforcing blocks are evenly arranged inside the filling layer, and the gaps inside the filling layer are filled with fillers. The material of the fillers is rubber, the outer tube is made of PVC, and the inner tube is made of braided metal wire.

[0017] By adopting the above technical solution, the reinforcing block of the solution strengthens the strength of the hose body, the rubber has a certain elasticity, the PVC material is soft and bendable, and the metal wire is woven to form the inner tube, which has strong stability.

[0018] The first corrosion-resistant layer and the second corrosion-resistant layer are both coated with epoxy coal tar paint, and the inner walls of the first threaded through hole and the second threaded through hole are both bonded with sealing gaskets.

The reinforcing block improves the strength of the hose, the anti-slip sheet ensures a tight connection and prevents loosening, and the sealing gasket improves the sealing performance to avoid sample leakage.
