Detailed Description

In order to reduce the use of internal parts of the pressure release valve, realize automatic pressure release and reduce cost, the one-way automatic pressure release valve is specially provided. 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.

Example 1

Please refer to fig. 1-2, the embodiment provides an one-way automatic pressure release valve, which includes a pipeline body 1, a sealing cover 2 is connected to the top of the pipeline body 1 through a hinge, one side of the sealing cover 2 close to the pipeline body 1 is provided with a circle of magnetic stripe 3, a sealing groove 4 matched with the magnetic stripe 3 is arranged at the top of the pipeline body 1, a pressure discharge pipe 5 is integrally arranged at the outer side of the top of the pipeline body 1, a pressure discharge hole 6 is arranged on the side wall of the pressure discharge pipe 5, and a sealing sleeve 7 made of rubber is sleeved at the outer side of the pressure.

The size of the sealing cover 2 is matched with that of the pipeline body 1, and the thickness of the sealing cover 2 is 0.5-1 cm.

The bottom side of the sealing groove 4 is provided with a second magnetic strip 41 which is matched with the magnetic strip 3 in polarity, and the size of the second magnetic strip 41 is the same as that of the magnetic strip 3.

The pressure discharge pipe 5 is of a sealed cylindrical shape.

The thickness of the sealing sleeve 7 is 0.05-0.3mm, the inner diameter of the sealing sleeve 7 is matched with the outer diameter of the pressure discharge pipe 5, the height of the sealing sleeve 7 is 10-15cm greater than that of the pressure discharge pipe 5, and the bottom of the sealing sleeve 7 is flush with that of the pressure discharge pipe 5.

In this embodiment, the inside atmospheric pressure of pipeline body 1 can produce a pressure to sealed lid 2, when the pressure that sealed lid 2 received is greater than the adhesive force between magnetic stripe 3 and the second magnetic stripe 41, sealed lid 2 and the top separation of pipeline body 1, the fluid flows to the pressure pipe 5 of pushing away through the gap between sealed lid 2 and the pipeline body 1 top, when the inside fluid of pipeline body 1 is less than the adhesive force between two magnets to sealed lid 2's pressure, realize sealed between the top of sealed lid 2 and pipeline body 1.

After the fluid enters the pressure exhaust pipe 5, the fluid passes through the pressure exhaust hole 6 and applies a pressure to the sealing sleeve 7, so that the connection part between the sealing sleeve 7 and the pressure exhaust hole 6 is deformed, and the fluid in the pressure exhaust pipe 5 is exhausted to the outside of the pressure exhaust pipe 5 through the deformed position of the sealing sleeve 7.

Through the cooperation of above each device use, can realize fluidic automatic pressure release to do not have the use of accurate part, the cost is reduced also makes things convenient for the maintenance in later stage to overhaul.

Example 2

Referring to fig. 1-2, a further improvement is made on the basis of embodiment 1: the pressure discharge hole 6 is provided with a plurality ofly, a plurality of pressure discharge holes 6 evenly distributed are at the outer wall of pressure discharge pipe 5, the side view of pressure discharge hole 6 is waist drum-shaped, and the bottom side of the pressure discharge hole 6 of one row that is closest to pipeline body 1 apart from the bottom distance of pressure discharge pipe 5 between 5-10cm, the shape of pressure discharge hole 6 can enough make things convenient for fluid discharge to the outside of pressure discharge pipe 5, can prevent again that the fluid from liquefying when the temperature reduces, and influence the normal clear of pressure release, and the position of pressure discharge hole 6 can also avoid pressing the inside fluid flow of pipe 5 because of the pressure discharge, normally open closed production influence to sealed lid 2.
