Description
Technical field
The utility model relates to the pressure limiting valve of motor car engine, specifically is a kind of pressure limiting valve pick-up unit.
Background technology
At present, in motor car engine when work,, the pump oil pressure of lubricating oil pump increases with engine speed, and silts up or the engine oil viscosity that uses when excessive when oil circuit in the lube system, and charge oil pressure will be increased.Therefore; In the oil duct of engine lube system, be provided with pressure limiting valve, when the oil pressure of engine lube system oil duct surpassed predetermined pressure, oil pressure overcame the pressure valve spring acting force; Back down valve; Part machine oil passage from the side flows in the oil sump, make oil pressure in the oil duct drop to the normal value of setting after, valve closing.In the present group process of assembling; Pressure required value according to oil circuit in the lube system directly is installed to corresponding pressure limiting valve on the engine; Check exists error and transportation reason to cause the pressure limiting valve fault when dispatching from the factory owing to pressure limiting valve; Directly pressure limiting valve is installed on the engine, will produces and make in the engine operation process engine oil pressure excessive because of the pressure limiting valve quality problems, engine capacity consumes excessive.Summary of the invention
The utility model technical matters to be solved is: a kind of pressure limiting valve pick-up unit is provided, can before installation, detects pressure limiting valve, minimizing is excessive because of the pressure limiting valve quality problems consume engine capacity.
The technical scheme that the utility model is taked is: a kind of pressure limiting valve pick-up unit is provided; It comprises hydraulic pump, be used to tensimeter and the flowmeter regulating the valve of flow and be used to show pressure and flow; The endpiece of said hydraulic pump is communicated with the entrance point of the entrance point of said valve and pressure limiting valve to be detected respectively through pipeline; The endpiece of described valve is communicated with fuel tank through pipeline; The endpiece of said pressure limiting valve is communicated with through pipeline and fuel tank, and described tensimeter is located at the endpiece of hydraulic pump, and described flowmeter is located at the endpiece of pressure limiting valve.
After adopting above pick-up unit, compared with prior art, the utility model has following advantage: through hydraulic pump to the pipeline transferring oil; Regulate the valve on the pipeline, make that the flow through valve reduces gradually on the pipeline, and the line pressure at pressure limiting valve place increases gradually; When confirming that through tensimeter pressure arrives the opening pressure of pressure limiting valve, observe flowmeter, confirm whether pressure limiting valve is opened; Thereby judge whether pressure limiting valve is qualified, this device can detect it before pressure limiting valve is installed once more, and simple in structure; Easy to operate, can avoid not limiting because of the pressure limiting valve quality problems have timely pressure to oil duct, make the oil duct hypertonia make power consumption excessive.
As preferably, described valve is a stop valve, the valve rod of stop valve open or shutoff stroke shorter relatively, and have and cut off function very reliably, the variation of valve seat port and the stroke of flap are proportional, are very suitable for the adjusting to flow.
As further preferred, also be provided with pressure indicator between the endpiece of said pressure limiting valve and the return line, pressure indicator is that numeral shows force value, can judge more accurately that the pressure limiting valve unlatching is to deny.
Preferred as further, the endpiece of described hydraulic pump also is provided with spill valve, and spill valve is set, and can play the effect of qualification to the pressure of pipeline, avoids pressure to exceed the pressure limit of pressure limiting valve.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Shown in accompanying drawing; A kind of pressure limiting valve pick-up unit; It comprises hydraulic pump 1, be used to tensimeter 3 and the flowmeter 5 regulating the valve 7 of flow and be used to show pressure and flow; Entrance point and the entrance point of to be detected pressure limiting valve 4 of the endpiece of said hydraulic pump 1 through pipeline and said valve 7 is communicated with, and the endpiece of described valve 7 is communicated with through pipeline and fuel tank, and the endpiece of said pressure limiting valve 4 is through pipeline and fuel tank connection; Described tensimeter 3 is located at the endpiece of hydraulic pump 1, and described flowmeter 5 is located at the endpiece of pressure limiting valve 4.
In this specific embodiment; Entrance point and the entrance point of to be detected pressure limiting valve 4 of the endpiece of described hydraulic pump 1 through pipeline and said valve 7 is communicated with; Just the pipeline at pressure limiting valve 4 places is parallelly connected with the pipeline at valve 7 places, and the entrance point of pressure limiting valve 4 all is communicated with the endpiece of hydraulic pump 1 with the entrance point of valve 7.
Described valve 7 is a stop valve, and stop valve is the valve of using always, because of its structure is highly suitable for regulating flow, and has directivity; The endpiece of the entrance point of described stop valve and hydraulic pump 1 passes through pipeline connection; The endpiece of described stop valve is communicated with through pipeline and fuel tank; Described oil flows out from hydraulic pump 1 and arrives stop valve, from the endpiece process pipeline arrival fuel tank of stop valve, thereby constitutes a loop.
The endpiece of said pressure limiting valve 4 also is provided with pressure indicator 6; Described pressure indicator 6 is located at the endpiece of flowmeter 5; Pressure indicator 6 is that numeral shows force value; Can judge more accurately whether oily process is arranged in the pipeline, described pressure indicator 6 is used for jointly judging with flowmeter 5 whether pressure limiting valve 4 is opened.
The endpiece of described hydraulic pump 1 also is provided with spill valve 2, avoids pressure to exceed the pressure limit of pressure limiting valve.
