Abstract
The utility model relates to an oil pressure indicating valve used on diesel engines. The oil pressure indicating valve is characterized in that distinguished from the existing oil pressure indicating valve whose valve core and valve scale are fixed into a whole, the valve core and the valve scale of the oil pressure indicating valve of the utility model is respectively closed; when working, the simultaneous motion of the valve core and the valve scale is realized by the induction of the magnet of the valve core and the magnet of the valve scale. The oil pressure indicating valve used on diesel engines has the advantages that the phenomena of oil seepage and oil leakage is avoided; the valve scale can not be polluted by oil and dust by being sealed in a transparent casing; the observation is convenient and obvious; the durability is permanent.
Description
The utility model relates to a kind of liquid pressure measurement device, especially for the engine oil pressure indicating valve of agricultural vehicle diesel engine.
Now to mark be by the fixing all-in-one-piece of valve rod for the spool of the engine oil pressure indicating valve of installing and using on the diesel engine and valve.During work, valve rod slides up and down at the housing center hole, the oil impregnate oil leakage phenomenon that this structure produces in valve rod and body clearance is difficult to avoid, after working after a while, the greasy dirt that seepage oil produces makes whole valve mark and transparent cover wall polluting serious, can't observe the valve mark, lose deixis.
The purpose of this utility model is to provide a kind of magnetic field principle that is used in, and spool and valve mark that each is self-enclosed, no leakage of oil oil impregnate phenomenon, and sign is obviously observed engine oil pressure indicating valve easily.
The working principle of model utility is achieved in that the engine oil pressure indicating valve is made up of mangetic core assembly and valve mark assembly two-part, and mangetic core assembly has: spool 1, valve rod 2, spring 3, guide pin bushing 4, magnet 5, jump ring 6, housing 7.Valve mark assembly has: magnet valve mark 8, transparent sealed cover 9, diaphragm seal 10.Housing 7 has up and down two not connected cavitys, above cavity internal thread is arranged, spring 3, guide pin bushing 4 are housed on the valve rod 2, guide pin bushing 4 is fixed in the cavity below the housing 7, valve rod 2 one ends are connected with spool 1, the interior magnet 5 of the other end and housing 7 following cavitys is connected.Transparent sealed cover 9 one ends have outside thread, and magnet valve mark 8 is equipped with in inside, by diaphragm seal 10 sealings.Valve mark assembly and mangetic core assembly are by the end outside thread of transparent sealed cover 9 and the female connection of housing 7 top cavitys.When designing by housing 7 end outside threads and diesel engine, engine oil pressure indicating valve integral body gives the female connection on the oil pocket top of staying.The oil pocket wall has one apart from the high 10 millimeters overflow hole of oil pocket bottom oil inlet hole, during work, pressure machine oil promotes spool 1, valve rod 2 moves up with magnet 5, magnet valve mark 8 is also moved up under the effect in magnetic field synchronously, pressure machine oil begins overflow when the bottom plane of spool 1 surpasses the overflow hole of oil pocket wall, the pressure in the oil pocket and the equalization of strain of spring 3, spool 1 and coupling component all stop to move up, reach steady state, at this moment can observe valve mark 8 and be suspended in the transparent sealed cover, realize the engine oil pressure indication.
This device has simple in structure, and observation is convenient and do not have oil impregnate, oil leakage phenomenon, and price is low holds concurrently advantages such as long service life.
The structure that model utility is concrete is provided by following examples and accompanying drawing.
Fig. 1 is engine oil pressure indicating valve structural drawing.
Provide an embodiment in conjunction with the accompanying drawings.
As shown in Figure 1, the engine oil pressure indicating valve is made of mangetic core assembly and valve mark assembly, utilizes the same sex mutually exclusive principle in magnetic field to carry out work.Housing 7 has two cavitys that do not communicate up and down, and the magnet valve mark 8 that constitutes valve mark assembly is to make with magnet, is contained in the cavity above the housing 7.The magnet 5 that constitutes the core member assembly is connected with valve rod 2, is contained in the following cavity of housing 7.
Claims (1)
1, a kind ofly constitutes the engine oil pressure indicating valve that utilizes the same sex mutually exclusive ability in magnetic field to carry out work by mangetic core assembly and valve mark assembly, it is characterized in that: the magnet valve mark (8) that constitutes valve mark assembly is made with magnet, and the valve rod (2) that magnet (5) also are housed with the formation mangetic core assembly is to be contained in respectively in the cavity that two do not communicate up and down of housing (7).
