Embodiment 1

[0017] A Venturi tube with a safety valve includes a pipe body 6, which is divided into an inlet section 1, an adsorption chamber 2, a contraction section 3, a throat 7 and a diffusion section 4, and a safety valve 5 is provided inside the pipe body 6.

[0018] The safety valve 5 includes a safety valve inlet 53 and a safety valve outlet 54. There is a spring 52 inside the safety valve 5. One end of the spring 52 is in contact with the top of the safety valve 5, and the other end is in contact with the piston 51. The upper part 12 of the inner wall of the safety valve 5 is a mesh 11. Both ends of the throat 7 are provided with a left transition section 10 and a right transition section 13 respectively, and the left transition section 10 and the right transition section 13 are fixedly connected with the conical shrinkage tube 8 and the conical diffuser tube 9 . The left transition section and the right transition section can protect the throat from deformation during installati...

Abstract

The invention relates to a Venturi tube with a safety valve. The Venturi tube comprises a tube body. The internal portion of the tube body includes an inlet section, an adsorption cavity, a contraction section, a throat portion and a diffusion section. The safety valve is arranged inside the tube body and comprises a safety valve inlet and a safety valve outlet, a spring is arranged inside the safety valve, one end of a spring is connected with the top of the safety valve, the other end of the spring is connected with a piston, the safety valve outlet is the empty portion between an inner wall and an outer wall of the upper half portion of the safety valve, and the inner wall of the upper half portion of the safety valve is meshy. When pressure of the inlet section and the contraction section inside the Venturi tube is overlarge, the piston is gradually pressed by the pressure towards the top direction of the safety valve. When the piston is pressed to the meshy inner wall portion, gas or liquid overflows from mesh holes gradually and then flows towards the outside through the safety valve outlet, the pressure reduction effect is achieved, burst and even explosion is prevented, and a safety guarantee function is played well.

Description

technical field [0001] The invention relates to a Venturi tube, in particular to a Venturi tube with a safety valve. Background technique [0002] Venturi tubes are widely used in the control and measurement of large-diameter fluids in petroleum, chemical, metallurgy, electric power and other industries. They have the characteristics of wide application range, convenient installation and long-term maintenance. However, the design lacks safety guarantees, and it is prone to bursting or even explosion accidents due to excessive pressure. Contents of the invention [0003] Aiming at the shortcoming that the existing Venturi tube explodes due to excessive pressure, the present invention proposes a Venturi tube with a safety valve. [0004] In order to solve the above technical problems, the present invention is solved through the following technical solutions: [0005] A Venturi tube with a safety valve includes a pipe body, which is divided into an inlet section, an adsorpt...
