Description

TECHNICAL FIELD

[0001] The utility model relates to the field of pipeline pressure relief, especially to a water supply and drainage pressurization anti-explosion pressure relief device. BACKGROUND

[0002] Water supply and drainage pressurization anti-explosion pressure relief refers to the safety measures taken in the water supply and drainage system to prevent excessive pressure in the pipeline. When the water pressure in the system exceeds the set safety range, it may cause damage to the pipeline, pump and other components, and even lead to serious accidents such as explosion or rupture. Therefore, the anti-explosion pressure relief mechanism is an important part of ensuring the safe operation of the system.

[0003] The existing water supply and drainage pressurization pipeline pressure relief is usually achieved through a pressure relief device installed on the pipeline. When the water pressure acts on the device, the internal spring deforms under stress, thereby opening the valve for pressure relief. However, the current pressure relief equipment only uses a single spring for repeated pressure relief operations, which can easily cause the spring to break due to fatigue, shorten the service life of the spring, and affect the efficiency of pressure relief, making it inconvenient to use.

[0004] Therefore, it is necessary to design a water supply and drainage pressurization anti-explosion pressure relief device that can switch the opening or closing of the baffles on both sides for intermittent pressure relief, facilitate switching, prevent the spring from breaking due to long-term use fatigue, prolong the service life of the spring, and use flexibly and conveniently. SUMMARY

[0005] In order to overcome the shortcomings of the current pressure relief equipment, which only uses a single spring for repeated pressure relief operations, easily causes the spring to break due to fatigue, shortens the service life of the spring, and affects the efficiency of pressure relief, making it inconvenient to use, the utility model provides a water supply and drainage pressurization anti-explosion pressure relief device that can switch the opening or closing of the baffles on both sides for intermittent pressure relief, facilitate switching, prevent the spring from breaking due to long-term use fatigue, prolong the service life of the spring, and use flexibly and conveniently.

[0006] The technical scheme of the utility model is: a water supply and drainage pressurization anti-explosion pressure relief device, comprising a water inlet pipe, a turbocharger pump, a pipeline, a flange, a bolt and a pressure relief assembly, the water inlet pipe is connected with the turbocharger pump on the front side, the pipeline is placed on the ground, the pipeline is located on the right side of the water inlet pipe, the turbocharger pump right side and the pipeline left side are both connected with the flange, six bolts are arranged between the flanges, the flanges are fixed by the bolts, and the pipeline is provided with a pressure relief assembly for pressure relief when the pipeline pressure is large.

[0007] Further, the diameter of the left part of the pipeline is smaller than that of the right part.

[0008] Furthermore, the pressure relief assembly includes a protective shell, a pressure relief pipe, a rotating frame, a limit block, a missing gear, a connecting block, a moving block, a spring, a piston, a rotating rod, a bevel gear and a baffle. The upper side of the pipeline is connected to the protective shell, and the upper sides of the left and right parts of the pipeline are connected to the pressure relief pipe, and the pressure relief pipes are connected to the protective shell. The upper part of the protective shell is rotatably connected to the rotating frame, and the limit block is connected to the rotating frame. The limit block is rotatably connected to the protective shell, and the lower side of the rotating frame is connected to the missing gear. The left and right parts of the protective shell are both slidably connected. There are pistons, which are all slidingly connected to the pressure relief pipe on the same side. There are connecting blocks slidingly connected to the pistons, and the sides of the connecting blocks close to each other are connected with moving blocks. The moving blocks are slidingly connected to the limit blocks. Springs are connected between the pistons and the connecting blocks on the same side. The lower part of the protective shell is rotatably connected to a rotating rod, and the pressure relief pipes are rotatably connected to the rotating rod. The middle part of the rotating rod is connected to a bevel gear, and the bevel gear is engaged with the missing gear. Baffles are connected to the left and right parts of the rotating rod, and the baffles are in contact with the pressure relief pipe on the same side.

[0009] Furthermore, the protective shell is made of transparent material.

[0010] Furthermore, a handle is provided on the upper portion of the rotating frame.

[0011] Furthermore, the pistons are all I-shaped.

[0012] The beneficial effect is that the utility model rotates the rotating frame to rotate the rotating rod, thereby switching the baffle to open or close, and then allowing water to enter the corresponding pressure relief pipe. Under the action of water, the piston moves, so that the water is discharged to relieve the pressure, thereby being able to switch the baffles on both sides to open or close for intermittent pressure relief, which is convenient for switching and use, prevents the spring from being fatigued and broken due to long-term use, extends the service life of the spring, and is flexible and convenient to use.
