Abstract
The utility model relates to a connecting rod supporting point type pressure regulator for LPG, which comprises a casing, an air inlet, a filter screen and an air outlet. The utility model is characterized in that a cavity is arranged in the casing in which a movable sealing strip is arranged, and the lower part of the cavity is sealed by the movable sealing strip. The middle part of the lower side of the movable sealing strip is provided with a connecting rod which is connected with a rotating arm, and a rotating shaft which is connected to a cavity wall is arranged on the top end of the rotating arm. A sealing strip is arranged on the top end surface of the rotating arm, the sealing strip is opposite to the air inlet arranged on the inner wall of the cavity and a spring is connected with the middle part of the upper surface of the movable sealing strip. The upper top end of the spring is opposite to the upper top surface of the cavity, and a slope which is outwards convex is arranged at the air inlet arranged on the inner wall of the cavity. The utility model has the advantages of simple and reliable structure, convenient installation and good stability.
Description
Technical field
The utility model relates to a kind of pressure governor, particularly a kind of connecting rod pivot formula pressure governor that is used for LPG.
Background technique
Moped is proper in many cities at present uses widely, the moped of original burns gasoline, make the exhaust gas discharged after the burning super accurate serious because added the machine oil of lubricating engine in its fuel oil, contaminated air, now for the pollution of the moped that reduces burns gasoline to atmosphere, a large amount of fuel oil mopeds have changed burning LPG into, but because LPG utilizes high-pressure cylinder storage LPG, need with after the LPG step-down of high pressure could with air mixing after deliver to the cylinder combustion work done, but the decompression pressure governor on the employed steel cylinder of the more employing liquefaction gas of the pressure governor of more existing decompressions kitchen range, because its complex structure is afraid of vibration, and range of regulation is little, when being used for the combustion gas moped, break down easily.
Summary of the invention
The purpose of this utility model is to solve decompression pressure governor of the prior art to exist complex structure to be afraid of vibration, and the little problem of range of regulation, provides a kind of simple and reliable for structure, the connecting rod pivot formula pressure governor that is used for LPG of good stability easy for installation.The utility model is designed for the connecting rod pivot formula pressure governor of LPG, comprise housing, suction port, filter screen, air outlet, it is characterized in that: cavity is arranged in housing, one movable sealing sheet is arranged in the cavity, the bottom of the airtight cavity of movable sealing sheet, there is connecting rod at the following middle part of movable sealing sheet, connecting rod is connected with a pivoted arm, have rotating shaft to be connected on the cavity wall on the top of pivoted arm, on the top end of pivoted arm diaphragm seal is arranged, diaphragm seal is with respect to the suction port on the cavity inner wall, the middle part is connected with spring on the movable sealing sheet, and the last top of spring is relative with the last end face of cavity.There is the inclined-plane of evagination at suction port place on cavity inner wall.The utility model has the advantages that simple and reliable for structure, good stability easy for installation.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated,
Accompanying drawing 1 is an opening state structural representation of the present utility model,
Accompanying drawing 2 is a closed condition structural representation of the present utility model,
Embodiment
Comprise housing 1, suction port 2 among the figure, filter screen 3, air outlet 4, it is characterized in that: cavity 5 is arranged in housing 1, one movable sealing sheet 6 is arranged in the cavity 5, the bottom of movable sealing sheet 6 airtight cavitys 5, there is connecting rod 7 at the following middle part of movable sealing sheet 6, connecting rod 7 is connected with a pivoted arm 8, there is rotating shaft 9 to be connected on cavity 5 walls on the top of pivoted arm 8, diaphragm seal 10 is arranged on the top end of pivoted arm 8, diaphragm seal 10 is with respect to the suction port 2 on cavity 5 inwalls, and the middle part is connected with spring 11 on movable sealing sheet 6, and the last top of spring 11 is relative with the last end face of cavity 5.There is the inclined-plane 12 of evagination at suction port 2 places on cavity 5 inwalls.Combustion gas during use in the high-pressure cylinder is injected in the cavity 5 after filter screen 3 enters suction port 2, this moment, cavity 5 interior pressure progressively raise, highpressure promotes to move on movable sealing sheet 6 pressure springs 11 backs, the connecting rod 7 that is fixed on the following middle part of movable sealing sheet 6 also moves on simultaneously, driving pivoted arm 89 rotates around the shaft, along with the pressure in the cavity 5 raises, the diaphragm seal 10 that pivoted arm 8 turns to pivoted arm 8 stops up the suction port on cavity 5 inwalls 2, stop the input of high-pressure gas, but the combustion gas after adjusting pressure is emitted by air outlet 4 simultaneously, with deliver to engine combustion after the air mixing, in case and after combustion gas discharged from air outlet 4, the pressure in the cavity 5 reduced, movable sealing sheet 6 is moved down by the reaction thrust effect of spring 11, reopen suction port 2, put into the combustion gas of high pressure once more, so keep a gradually voltage regulation of voltage regulation process of section.
Claims (2)
1, the connecting rod pivot formula pressure governor that is used for LPG, comprise housing, suction port, filter screen, air outlet, it is characterized in that: cavity is arranged in housing, one movable sealing sheet is arranged in the cavity, the bottom of the airtight cavity of movable sealing sheet, there is connecting rod at the following middle part of movable sealing sheet, connecting rod is connected with a pivoted arm, have rotating shaft to be connected on the cavity wall on the top of pivoted arm, on the top end of pivoted arm diaphragm seal is arranged, diaphragm seal is with respect to the suction port on the cavity inner wall, the middle part is connected with spring on the movable sealing sheet, and the last top of spring is relative with the last end face of cavity.
2, by the described connecting rod pivot formula pressure governor that is used for LPG of claim 1, it is characterized in that: there is the inclined-plane of evagination at the suction port place on cavity inner wall.
