[0006] Preferably, a cross groove is provided at the inner bottom of the plug body.
[0007] Preferably, a first sealing ring is nested on the ceramic plate, and a second sealing ring is nested on the plug body.
[0008] Preferably, a cap is sleeved on one end of the plug body.
[0009] Preferably, a first annular boss is fixed to one end of the plug body.
[0010] Preferably, a sealing gasket is sleeved on the plug body, and the sealing gasket is tightly against the first boss.
[0011] Preferably, an annular second boss is fixed on the first boss, a screw is sleeved on the second boss via a thread, a pressure plate is fixed to one end of the screw, and a knob is fixed to the other end of the screw.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] 1. In the utility model, the plug body is made of metal, which has higher strength and is not easy to crack. The plug body with a sleeve-shaped structure can save materials. The threaded section is used to connect with the water pipe through threads, which is convenient for disassembly and assembly. The ceramic plate has heat-resistant and frost-resistant properties and a longer service life. The heat insulation board can reduce the heat transfer to the plug body, which helps to reduce the heating and freezing of the plug body and helps to increase the life of the plug body.
[0014] 2. In the utility model, the cross groove facilitates the screwdriver to rotate the plug body, thereby facilitating the disassembly and assembly of the plug body. The first sealing ring and the second sealing ring can improve the airtightness and reduce leakage. The cap is used to cover the port of the plug body. The sealing gasket can improve the airtightness of the port when the plug body is installed in the water pipe. The screw is rotated by turning the knob, and the screw pushes the pressure plate to press tightly on the water pipe, which can improve the stability of the connection of the plug body and reduce looseness.
