Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Referring to fig. 1-3, a mechanical seal convenient to change sealing ring, includes transmission pipe 1 and switching pipe 3, the welding of 1 one end of transmission pipe has first flange 2, the welding of 3 bottom of switching pipe has sleeve pipe 4, the sleeve pipe 4 inside callipers is equipped with flexible pipe 5, the welding of 5 one end of flexible pipe has second flange 6, and the welding of 5 one end of flexible pipe has apron 9, the card is equipped with second sealing ring 10 between apron 9 and the sleeve pipe 4 one end, and the welding of 5 skin joints of flexible pipe has snap ring 8, the welding of 8 outsides of snap ring has cardboard 11, and flexible pipe 5 surface is located cardboard 11 both sides are overlapped respectively and are equipped with third sealing ring 12 and fourth sealing ring 13.
The telescopic pipe is characterized in that a first sealing ring 7 is clamped between the first flange 2 and the second flange 6, the first flange 2 is connected with the second flange 6 through bolts, the cover plate 9 is connected with one end of the sleeve pipe 4 through screws, a clamping groove matched with the clamping plate 11 is formed in one end of the sleeve pipe 4, the outer sides of the third sealing ring 12 and the fourth sealing ring 13 are in close contact with the inner side of one end of the sleeve pipe 4, and a circulation hole is formed in the surface of the telescopic pipe 5 and is positioned in the sleeve pipe 4.
In this embodiment, the cover plate 9 is effectively fixed to one end of the sleeve 4 by screws, the second seal ring 10 is disposed between the cover plate 9 and the end of the sleeve 4 to prevent leakage of the internal transmission material, and after the fixation, the clamping plate 11 is clamped in a clamping groove in one end of the sleeve 4, the third sealing ring 12 and the fourth sealing ring 13 are clamped between the clamping ring 8 and the inner side of one end of the sleeve 4 to prevent the leakage of the transmission material in the sleeve 4, then the second flange 6 at the end part of the extension tube 5 is connected with the first flange 2 at the end part of the transmission tube 1 through bolts, the first sealing ring 7 between the second flange 6 and the first flange 2 prevents the leakage in the transmission process, after the transmission material in the transmission tube 1 enters the extension tube 5, flows out from the circulation hole on the surface, enters the sleeve 4, then flows through the adapter tube 3, and flows in from the circulation hole on the surface of the extension tube 5 at the other end, thus completing the transmission work.
