Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1, the utility model relates to a but pressure regulating formula tee bend structure constitutes including upper cover 1, screw 2, knob 3, mounting 4, pressure regulation shell 5, screw rod 6, spring holder 7, spring 8, pressure regulating piston 9, well core rod 10, sealed pad 11, tee bend body 12 and lower cover 13. The installation mode is that an upper cover 1 is installed on the top of a knob 3 through an O-shaped sealing ring, a screw 2 and a screw rod 6 are fixed in the middle of the knob 3 through thread fit, the screw rod 6 and a pressure adjusting shell 5 are fixed through a fixing piece 4, the pressure adjusting shell 5 is connected with a three-way body 12 through threads and the O-shaped sealing ring, the screw rod 6 penetrates through the pressure adjusting shell 5 to be connected with a spring seat 7 in the pressure adjusting shell 5 through threads, the upper end of a spring 8 is connected with the top of a pressure adjusting piston 9, the upper end of a central rod 10 is connected with the bottom of the pressure adjusting piston 9, a sealing gasket 11 is installed at the lower end of the central rod 10, the three-way body 12 comprises a front water cavity 12-1 and a rear water cavity 12-2, the front water cavity 12-1 is communicated with the rear water cavity 12-2 through a water, the lower cover 13 is installed at the bottom of the tee body 12 through threads and an O-shaped sealing ring.
