Abstract
The invention discloses a fuel pressure adjuster. The fuel pressure adjuster comprises an adjuster body, an oil inlet, an oil outlet and the like, and is characterized by further comprising a filter layer and pressure meters; a spring chamber and a combustion chamber are formed in the adjuster body, and are connected through a diaphragm; a spring is arranged in the spring chamber; one side of the spring chamber is connected with a ventilation pipe; and the filter layer is arranged in the ventilation pipe. A thread is arranged on the outer wall of the oil outlet, so that the assembly is tighter and more stable; as the pressure meters are respectively arranged on the oil inlet and the oil outlet, operators can judge the equipment working state through data displayed on the pressure meters, and the convenience is provided for maintenance when the equipment is broken down; and the filter layer is added in the ventilation pipe for filtering impurities in gas to prevent the impurities from entering to cause loose matching between the diaphragm and an oil return valve or work failure of the oil return valve.
Description
Technical field
The present invention relates to a kind of pressure regulator, more particularly to a kind of fuel pressure regulator.
Background technology
Fuel pressure regulator is to ensure that automobile oil-way intermediate fuel oil pressure is normal, avoid the too low fuel injector oil spout of oil pressure too weak or the too high part for causing fuel injector to damage of oil pressure.Existing fuel pressure regulator is provided with breather line to improve degree of regulation in the side of spring housing, but the portable impurity in the gas of pipeline, impurity is entered, and causes diaphragm with oil return valve loose contact or blocking so that oil return valve operational failure；And pressure value directly can not be shown by traditional fuel pressure regulator in the course of the work, during failure, staff needs unit test in turn to judge whether to damage at the equipment, and maintenance work is carried out slowly；Additionally, oil-out is connected by bolt hole with fuel injector, sealing is poor, fluid is revealed and easily causes energy waste and cause potential safety hazard.
The content of the invention
According to above technical problem, the present invention provides a kind of fuel pressure regulator, including governor body, oil-in, oil-out, spring housing, spring, combustor, diaphragm, breather, oil return valve, it is characterised in that：Also include filter layer, pressure gauge, the governor body is internally provided with spring housing and combustor, the spring housing and combustor are connected by diaphragm, spring is provided with the spring room, the side of the spring housing is connected with breather, filter layer is provided with the breather, the bottom of the spring housing is connected with diaphragm, oil return valve is installed on the diaphragm, the bottom connection combustor of the diaphragm, the side of the combustor offers oil-in, and bottom to offer and be provided with pressure gauge on the inwall of oil-out, the oil-in and oil-out.
Beneficial effects of the present invention are：The present invention provides a kind of fuel pressure regulator, original fuel pressure regulator is improved, screw thread is provided with the outer wall of oil-out, dual fixed form is fixed with fixing hole using being screwed, so that assembling is more tight, stable, it is to avoid fluid is revealed and causes energy waste and cause potential safety hazard；Pressure gauge is provided with oil-in and oil-out, the data difference that operator can pass through to show on pressure gauge judges equipment working state, is maintenance provides convenient when equipment is out of order；Filter layer is set up in the inside of breather, the impurity in gas is filtered, it is to avoid impurity is entered causes diaphragm to coordinate not tight or oil return valve operational failure with oil return valve.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 positions external structure schematic diagram of the present invention.
Specific embodiment
According to Fig. 1, the present invention is further described：
Such as Fig. 1, governor body -1, oil-in -2, oil-out -3, spring housing -4, spring -5, combustor -6, diaphragm -7, breather -8, filter layer -9, pressure gauge -10, oil return valve -11.
Embodiment 1
The present invention provides a kind of fuel pressure regulator, including governor body 1, oil-in 2, oil-out 3, spring housing 4, spring 5, combustor 6, diaphragm 7, breather 8, filter layer 9, pressure gauge 10, oil return valve 11, the inside of governor body 1 arranges spring housing 4 and combustor 6, spring housing 4 and combustor 6 are connected by diaphragm 7, spring 5 is set in spring housing 4, the side of spring housing 4 is connected with breather 8, filter layer 9 is set in breather 8, the bottom of spring housing 4 is connected with diaphragm 7, oil return valve 11 is installed on diaphragm 7, the bottom connection combustor 6 of diaphragm 7, the side of combustor 6 opens up oil-in 2, bottom offers oil-out 3, pressure gauge 10 is installed on the inwall of oil-in 2 and oil-out 3.
Embodiment 2
Fuel oil is entered by oil-in 2, and when oil pressure exceeds standard value, high pressure fuel can be pushed, oil return valve 11 is opened, and unnecessary fuel oil Jing oil-outs 3 backflow fuel tank internal, when pressure is less than standard value, spring 5 can push diaphragm 7 and close oil return valve 11, stop oil return.Pressure gauge 10 is provided with oil-in 2 and oil-out 3, the data difference that operator can pass through to show on pressure gauge 10 judges equipment working state, is maintenance provides convenient；Filter layer 9 is set up in the inside of breather 8, the impurity in gas is filtered, it is to avoid impurity is entered causes diaphragm 7 to coordinate not tight or 11 operational failure of oil return valve with oil return valve 11.
The above is only the preferred embodiment of the present invention, it is noted that for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvement, and these improvement also should be regarded as protection scope of the present invention.
