Technical Field
The utility model relates to a water purification and water heater part field, in particular to prevent pipeline pressure-bearing tee bend structure.
Background
The tee joint is also called a pipe fitting tee joint, a three-way pipe fitting, a tee joint and the like, is mainly used for changing the direction of fluid and is used at a branch pipe of a main pipeline. The existing tee joint structure in the market at present is only for the effect of shunting, and back end water closes back pressure and can transmit to the back end product, makes the back end product pressure-bearing, because of there is the change in running water pressure, easily makes the product pressure-bearing impaired.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a prevent pipeline pressure-bearing tee bend structure, solve present tee bend structure rear end water effectively and close the back pressure and can transmit to the rear end product, make the rear end product pressure-bearing, have the change because of running water pressure, easily make the impaired problem of product pressure-bearing.
In order to achieve the above object, the utility model provides a following technical scheme:
a three-way structure for preventing a pipeline from bearing pressure comprises an upper cover, a spring, a pressure regulating piston, a central rod, a sealing gasket, a three-way body and a lower cover; the upper cover passes through the screw thread and the O type sealing washer is installed tee bend body top, the upper cover is connected to the upper end of spring, the top of pressure regulating piston is connected to the lower extreme of spring, the bottom of pressure regulating piston is connected to well core rod's upper end, well core rod's lower extreme installation is sealed to fill up, the tee bend body includes preceding water cavity and back water cavity, and preceding water cavity and back water cavity pass through the delivery port intercommunication, well core rod is located in the middle of the delivery port, the lower cover passes through the screw thread and the O type sealing washer is installed tee bend body bottom.
According to an aspect of the invention, the central rod is movable up and down under the action of the spring.
According to an aspect of the present invention, the sealing gasket may open or seal the water outlet along with the up-and-down movement of the central rod.
Due to the adoption of the scheme, the beneficial effects of the utility model are that:
the utility model discloses a tee bend structure is equipped with a water inlet, and many delivery ports when the delivery port is in the closed condition, the passageway is closed in the meeting of tee bend in time, makes the rear end product not bear the pressure, prevents that the running water pressure change from causing the rear end product impaired, and simultaneously, the tee bend adopts high strength material, can bear the running water pressure of change.

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 figure 1, the utility model relates to a prevent pipeline pressure-bearing tee bend structure constitutes including upper cover 1, spring 2, pressure regulating piston 3, well core rod 4, sealed pad 5, tee bend body 6 and lower cover 7. The mounting mode is that the upper cover 1 is mounted at the top of the tee body 6 through threads and an O-shaped sealing ring, the upper end of the spring 2 is connected with the upper cover 1, the lower end of the spring 2 is connected with the top of the pressure regulating piston 3, the upper end of the central rod 4 is connected with the bottom of the pressure regulating piston 3, the lower end of the central rod 4 is provided with a sealing gasket 5, the tee body 6 comprises a front water cavity 6-1 and a rear water cavity 6-2, the front water cavity 6-1 and the rear water cavity 6-2 are communicated through a water outlet 6-3, the central rod 4 is positioned in the middle of the water outlet 6-3, and the lower cover 7 is mounted at the.
The working principle of the present invention refers to fig. 2 and 3.
As shown in fig. 2, the water passage state: the central rod 4 moves downwards under the action of the spring 2, the water outlet 6-3 is opened, when the product is filled with water, the water flows from the front water cavity 6-1 to the rear water cavity 6-2 through the water outlet 6-3, the pressure of the rear water cavity 6-2 is gradually increased to force the pressure regulating piston 3 to move upwards, and the aperture of the water outlet 6-3 is reduced to be balanced in pressure.
As shown in fig. 3, the water-off state: when the water at the rear end of the tee joint is closed, the pressure of the rear water cavity 6-2 is gradually increased to force the pressure regulating piston 3 to continuously move upwards to the sealing gasket 5 below the central rod 4 to seal the water outlet 6-3, so that the water path at the rear end of the tee joint is protected.
The embodiments described above are described to facilitate understanding and application of the present patent to those of ordinary skill in the art. It will be readily apparent to those skilled in the art that various modifications to these embodiments may be made, and the generic principles described herein may be applied to other embodiments without the use of the inventive faculty.
