Description

Connecting Rod Pivot Point Regulator for LPG

technical field

The utility model relates to a voltage regulator, in particular to a connecting rod fulcrum type voltage regulator for LPG.

Background technique

At present, power-assisted bicycles are widely used in many cities. The original gasoline-burning power-assisted bicycles, because the fuel is added with engine oil to lubricate the engine, make the exhaust gas after combustion extremely serious and pollute the air. Now in order to reduce the burning of gasoline A large number of fuel-assisted bicycles are replaced by burning LPG. However, since LPG is stored in high-pressure cylinders, the high-pressure LPG needs to be depressurized before it can be mixed with air and sent to the cylinder for combustion. However, some existing decompression regulators mostly use the decompression regulator on the steel cylinder used in the liquefied gas stove. Because of its complex structure, it is afraid of vibration and the pressure regulation range is small. When used for gas-assisted bicycles, prone to failure.

Contents of the invention

The purpose of this utility model is to solve the problems of complex structure, fear of vibration and small pressure regulation range in the decompression regulator in the prior art, and provide a connecting rod for LPG with simple and reliable structure, convenient installation and good stability Fulcrum regulator. The utility model is designed for a connecting rod fulcrum type pressure regulator for LPG, including a shell, an air inlet, a filter screen, and an air outlet. There is a connecting rod in the middle of the lower part of the movable sealing plate, and the connecting rod is connected with a rotating arm. There is a rotating shaft on the top of the rotating arm connected to the wall of the cavity. There is a sealing plate on the top surface of the rotating arm. The sealing plate Relative to the air inlet on the inner wall of the cavity, a spring is connected to the upper middle of the movable sealing sheet, and the upper top of the spring is opposite to the upper top surface of the cavity. There is a convex slope at the air inlet on the inner wall of the cavity. The utility model has the advantages of simple and reliable structure, convenient installation and good stability.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is described in detail,

Accompanying drawing 1 is the structural representation of the open state of the utility model,

Accompanying drawing 2 is the closed state structure schematic diagram of the utility model,

Detailed ways

The figure includes a housing 1, an air inlet 2, a filter screen 3, and an air outlet 4. It is characterized in that: there is a cavity 5 in the housing 1, and there is a movable sealing piece 6 in the cavity 5, and the movable sealing piece 6 seals the cavity The lower part of the body 5, the lower middle part of the movable sealing plate 6 has a connecting rod 7, the connecting rod 7 is connected with a rotating arm 8, and a rotating shaft 9 is arranged on the top of the rotating arm 8 to be connected on the wall of the cavity 5, and the top surface of the rotating arm 8 Sealing sheet 10 is arranged, and sealing sheet 10 is connected with spring 11 at the upper middle part of movable sealing sheet 6 relative to the air inlet 2 on the inner wall of cavity 5 , and the upper top of spring 11 is opposite to the upper top surface of cavity 5 . There is a convex slope 12 at the air inlet 2 on the inner wall of the cavity 5 . When in use, the gas in the high-pressure steel cylinder enters the air inlet 2 through the filter screen 3 and is injected into the cavity 5. At this time, the pressure in the cavity 5 gradually increases, and the high air pressure pushes the movable sealing piece 6 to compress the spring 11 and then moves upward. The connecting rod 7 fixed on the lower middle part of the movable sealing sheet 6 also moves up at the same time, driving the rotating arm 8 to rotate around the rotating shaft 9, and as the pressure in the cavity 5 rises, the rotating arm 8 rotates to the sealing sheet 10 of the rotating arm 8 Block the air inlet 2 on the inner wall of the cavity 5, stop the input of high-pressure gas, but at the same time, the gas after adjusting the pressure is released from the gas outlet 4, mixed with air and sent to the engine for combustion, and once the gas is released from the gas outlet 4 Afterwards, the pressure in the cavity 5 decreases, and the movable sealing plate 6 is moved down by the anti-thrust effect of the spring 11, and the air inlet 2 is reopened, and the high-pressure gas is put in again, so as to maintain a gradual pressure regulation process.
