Description

Technical Field

[0001] This utility model relates to the field of pipeline pressure regulator technology, and in particular to an adaptive pressure regulator for alcohol-based fuel pipelines. Background Technology

[0002] When liquids are transported in pipelines, the internal pressure of the pipeline increases. This is especially true for pipelines transporting alcohol-based fuels, where it is essential to ensure stable pipeline pressure. If a pipeline ruptures due to pressure, causing an alcohol-based fuel leak, it can easily lead to environmental pollution and safety accidents.

[0003] A document with publication number CN201288916Y discloses an angle-type pipeline pressure stabilizer, which consists of a shell, a cover, a float, an elastic diaphragm, a spring, and an adjusting screw. Its key features are: an inlet at the bottom of the shell, an outlet on the side of the shell perpendicular to the inlet, and a float made of non-toxic, heat-resistant plastic inside the shell along the inlet direction. The float is divided into upper and lower parts. The lower part of the float is fitted into the conical outlet of the shell, located inside the inlet, and its bottom is elliptical. The upper part of the float presses against the elastic diaphragm, which is located between the shell and the cover and fixed by bolts. The up-and-down movement of the float under the elastic diaphragm changes the flow cross-sectional area of ​​the water, thus stabilizing the pressure outside the outlet. It has advantages such as simple structure, convenient installation and debugging, and stable outlet pressure.

[0004] When this type of pressure regulator is in use, it relies on the buoyancy of the float to control the amount of water entering the pipe. If the water pressure in the pipe suddenly increases, the float will rise with a lag and will not rise immediately, reducing the flow area of ​​the water. The pressure at the outlet will rise suddenly, which poses a certain safety hazard.

[0005] Therefore, it is necessary to provide an alcohol-based fuel pipeline pressure adaptive regulator to solve the above-mentioned technical problems. Utility Model Content

[0006] In view of the above situation and to overcome the defects of the existing technology, this utility model provides an alcohol-based fuel pipeline pressure adaptive regulator that can quickly reduce the internal pressure of the regulator body and improve the safety of the device.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] An alcohol-based fuel pipeline pressure adaptive regulator includes: a regulator body and a buffer, with a connecting pipe installed between the regulator body and the buffer body; the buffer body includes a housing and an elastic diaphragm installed inside the housing, the elastic diaphragm dividing the interior of the housing into a gas chamber and a liquid chamber, and an inert gas is injected into the gas chamber to balance the pressure of the gas chamber and the liquid chamber.

[0009] Preferably, the voltage stabilizer body is provided with an inlet, an outlet and a connecting port. The connecting port is connected to one end of the connecting pipe. A conical connecting port is provided on one side of the inlet. A float is installed inside the voltage stabilizer body. The bottom end of the float is conical and a diaphragm is provided at the top of the float. The diaphragm is connected to the top of the float.

[0010] Preferably, a magnet is fixedly installed at the top of the float, and an iron sheet is fixedly installed on the diaphragm.

[0011] Preferably, a top rod is installed above the diaphragm, an adjusting screw is installed on the voltage regulator body, a spring is installed between the adjusting screw and the top rod, and the bottom end of the top rod is pressed tightly against the top of the diaphragm.

[0012] Preferably, an intake and exhaust pipe is installed on the top of the buffer, and a valve is installed on the intake and exhaust pipe.

[0013] Preferably, a pressure gauge is installed on the intake and exhaust pipes.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) This utility model sets up a voltage regulator body and a buffer, and sets an elastic membrane in the buffer to divide the inside of the buffer into a gas chamber and a liquid chamber. By taking advantage of the fact that gas is easier to compress, it can help to quickly reduce the internal pressure of the voltage regulator body and improve the safety of the use of alcohol-based fuel delivery pipeline.

[0016] (2) By installing a float and a diaphragm inside the voltage stabilizer body and connecting and fixing the float and the diaphragm, the voltage stabilizer body no longer relies on the buoyancy of the float to move up and down. This reduces the restriction on the installation direction of the voltage stabilizer body, making the float more sensitive and more conducive to stabilizing pipeline pressure.

[0017] (3) By installing a magnet block at the top of the float and fixing an iron sheet on the diaphragm, this utility model can facilitate the connection and fixation of the float and the diaphragm.

[0018] (4) By setting a top rod, adjusting screw and spring, this utility model can conveniently adjust the external liquid supply pressure of the water outlet;

[0019] (5) By installing a pressure gauge on the intake and exhaust pipes, this utility model can conveniently control the inflation pressure and conveniently judge the pressure change trend inside the regulator body. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0025] Example 1:

[0026] like Figure 1-3 As shown, the present invention provides an adaptive pressure regulator for alcohol-based fuel pipelines, comprising: a regulator body 1 and a buffer 2, with a connecting pipe 3 installed between the regulator body 1 and the buffer body 2; the regulator body 1 is installed on the alcohol-based fuel delivery pipeline; after the alcohol-based fuel enters the regulator body 1, part of it flows back into the alcohol-based fuel delivery pipeline, and part of it enters the buffer body 2 through the connecting pipe 3; the buffer body 2 includes a shell and an elastic membrane 21 installed inside the shell, the elastic membrane 21 having a thickness of at least 5 mm, and its material can be rubber; the elastic membrane 21 divides the interior of the shell into an upper gas chamber and a lower liquid chamber, the connecting pipe 3 connects to the liquid chamber, and an appropriate amount of inert gas is injected into the gas chamber to balance the pressure of the gas chamber and the liquid chamber. When in use, when the pressure at the outlet of the regulator body 1 suddenly increases, more alcohol-based fuel enters the liquid chamber, forcing the elastic membrane 21 to deform and compress the volume of inert gas in the gas chamber. Through the compression of the inert gas, the internal pressure of the regulator body 1 is reduced, thereby reducing the outlet pressure of the regulator body 1 and improving the safety of the alcohol-based fuel delivery pipeline. Because the gas molecules are widely spaced, they are more easily compressed, and the response speed to changes in the internal pressure of the pipeline is faster and more sensitive, enabling a more rapid reduction in the internal pressure of the pipeline.

[0027] By setting up a pressure regulator body 1 and a buffer 2, and setting an elastic membrane 21 inside the buffer 2, the interior of the buffer 2 is divided into a gas chamber and a liquid chamber. By utilizing the characteristic that gas is easier to compress, it is possible to quickly reduce the internal pressure of the pressure regulator body 1 and improve the safety of the alcohol-based fuel delivery pipeline.

[0028] Example 2:

[0029] like Figure 3 As shown, in this embodiment, the voltage regulator body 1 is provided with an inlet 11, an outlet 12 and a connecting port 13. The inlet 11 and the outlet 12 are connected to the alcohol-based fuel delivery pipeline, and the connecting port 13 is connected to one end of the connecting pipe 3. A conical connecting port 15 is provided on one side of the inlet 11. A float 14 is installed inside the voltage regulator body 1. The bottom end of the float 14 is conical, and a diaphragm 16 is provided at the top end of the float 14. The diaphragm 16 is connected to the top end of the float 14. In use, alcohol-based fuel enters through inlet 11 and passes through the gap between float 14 and connection port 15. Part of it returns to the delivery pipe through outlet 12, while the other part enters the connecting pipe 3 through connection port 13 and then enters the buffer 2. When the pressure in inlet 11 suddenly increases, the liquid flow rate through connection port 13 increases, which inevitably increases the internal pressure on the other side of connection port 13 of the pressure regulator body 1. This forces the middle part of diaphragm 16 to bulge upward and deform, thereby pulling float 14 to move upward rapidly. This reduces the gap between float 14 and connection port 15, decreases the liquid flow rate, and thus reduces the outlet pressure of outlet 12. Conversely, when the pressure inlet 11 decreases, the middle part of diaphragm descends, forcing float 14 to descend, increasing the gap between float 14 and connection port 15, increasing the liquid flow rate, and increasing the outlet pressure of outlet 12. Ultimately, the pressure inlet 11 and outlet 12 reach a balance, playing an adaptive role in stabilizing the liquid pressure. It is worth noting that the float 14 is fixedly connected to the diaphragm 16, and its movement is no longer dependent on the buoyancy of the float 14. This makes the float 14 more responsive and more conducive to stabilizing pipeline pressure.

[0030] By installing a float 14 and a diaphragm 16 inside the pressure regulator body 1 and connecting and fixing the float 14 and the diaphragm 16, the buoyancy of the float 14 is no longer relied upon to make it rise and fall, thereby reducing the restriction on the installation direction of the pressure regulator body 1. This makes the float 14 more sensitive and more conducive to stabilizing pipeline pressure.

[0031] Example 3:

[0032] like Figure 3 As shown, in this embodiment, a magnet block 141 is installed at the top of the float 14, and an iron sheet is fixedly installed on the diaphragm 16. The iron sheet can be installed on the top of the diaphragm 16 or embedded in the diaphragm 16. The magnet block 141 attracts the iron sheet, so that the diaphragm 16 and the float 14 are magnetically attracted and fixed.

[0033] By installing a magnet block 141 at the top of the float 14 and fixing an iron sheet on the diaphragm 16, the connection and fixation between the float 14 and the diaphragm 16 can be easily achieved.

[0034] Example 4:

[0035] like Figure 3 As shown, in this embodiment, a top rod 17 is installed above the diaphragm 14. The top rod 17 is slidably installed inside the pressure regulator body 1. An adjusting screw 18 is installed on the pressure regulator body 1. A spring 19 is installed between the adjusting screw 18 and the top rod 17. The bottom end of the top rod 17 is pressed tightly against the top of the diaphragm 16. In use, the adjusting screw 18 is rotated to lower it, thereby compressing the spring 19 and forcing the top rod 17 to lower. The lowering of the top rod 17 pushes the float 14 to lower, thereby increasing the gap between the float 14 and the connection port 15, and increasing the external liquid supply pressure of the outlet 12 on the pressure regulator body 1.

[0036] By setting the top rod 17, adjusting screw 18 and spring 19, the external liquid supply pressure of the outlet 12 can be easily adjusted.

[0037] Example 5:

[0038] like Figure 2 As shown, in this embodiment, an air inlet / outlet pipe 22 is installed on the top of the buffer 2, and a valve 23 is installed on the air inlet / outlet pipe 22. When in use, inert gas is injected into the gas chamber of the buffer 2 through the air inlet / outlet pipe 22 until the pressure inside the gas chamber is balanced with the pressure at the outlet 12.

[0039] By installing an intake and exhaust pipe 22 on the top of the buffer 2, the intake and exhaust of the buffer 2 can be facilitated.

[0040] Example 6:

[0041] like Figure 2 As shown, a pressure gauge 24 is installed on the inlet and outlet pipes 22. During use, the pressure change of the gas chamber can be observed through the pressure gauge 24, which facilitates the inflation process and prevents the gas chamber pressure from becoming too high. At the same time, the direction of the pointer swing of the pressure gauge 24 can be used to easily determine the pressure change trend inside the voltage regulator body 1.

[0042] By installing a pressure gauge 24 on the intake and exhaust pipes 22, the inflation pressure can be easily controlled, and the pressure change trend inside the regulator body 1 can be easily determined.

[0043] Working principle: When in use, when the pressure at the outlet of the pressure regulator body 1 suddenly increases, the amount of alcohol-based fuel entering the liquid chamber increases, forcing the elastic membrane 21 to deform and compressing the volume of inert gas in the gas chamber. Through the compression of the inert gas, the internal pressure of the pressure regulator body 1 is rapidly reduced, thereby reducing the outlet pressure of the pressure regulator body 1 and improving the safety of the alcohol-based fuel delivery pipeline.
