Abstract
The utility model relates to an oil outlet detector, which is composed of an oil inlet valve body, a valve rod, an oil outlet pipe and a valve sleeve, wherein, one end of the valve rod is an oil through cavity, and the other end of the valve rod is enlarged into a plunger head which is matched with the large cavity of the valve body; the end of the oil through cavity is provided with an oil outlet on the side direction, the plunger head is provided with a magnet, and the magnet is provided with a spring; a dry reed pipe is arranged between the valve cover and the valve body, and a contact piece in the dry reed pipe is connected with an externally connected circuit. The utility model has the advantages of fast and sensitive reaction to the flow-out state, stable and reliable work and long service life, and is especially suitable for large machine devices with centralization lubrication.
Description
Whether normally the utility model relates to a kind of oil circuit detecting sensor, be a kind of each lubricant passage way utensil of circulation that detects.
For keeping working well of mechanical motion part, between movement parts, must apply profit oil at regular time and quantity, to arranging corresponding lubricant passage way on each movement parts contact point,, and oil circuit circulation sensor is set in each fuel-displaced pipeline so that centralized oil supply is lubricated.Current to adopt sensor be a kind of contact microswitch, and it is a kind of reed-type contact switch, and inertia is big, poor stability, sensitivity are low, easily aging malfunctioning, and difficulty debates not that certain oil circuit stops up live.In case generation mechanical fault, component wear are quite serious.This sensor directly drives by oil pressure in addition, and oil circuit must turn to, and Installation and Debugging and maintenance are very inconvenient, in case lubricant passage way is out of order, repairs certain oil site and must spend many times, influence production efficiency.
The purpose of this utility model is at above-mentioned shortcoming, designs a kind of lubricating oil appliance of highly sensitive stable performance, and can reach the fast and convenient purpose of Installation and Debugging maintenance.
Design proposal of the present utility model is, a kind of fuel-displaced detecting device, it is made up of oil inlet pipe, flowline, valve body, valve rod and valve pocket, valve rod one end is logical oil pocket, the other end is to expand the stopper head that matches with the big chamber of valve body, and logical oil pocket end side is established spring to oil outlet is arranged on the stopper head, between valve pocket and the valve body tongue tube is arranged, the contact in the tongue tube links to each other with external circuits.
Fig. 1 is a sectional view of the present utility model.
Structure and the course of action of embodiment are described below in conjunction with accompanying drawing.
The oil inlet pipe of fuel-displaced detecting device (1) links to each other with divider, and flowline (11) joins with oil site.Flowline (11) and oil inlet pipe (1) are fastened in the valve body (2) by double-deck chock plug (10) sealing.The valve body chamber enlarges for ladder from left to right, oil inlet pipe (1) joint is a loculus, valve rod (4) and valve body lumen are and are slidingly matched, valve body (4) one ends have logical oil pocket (3), the other end expands and becomes the stopper head (15) that matches with the big chamber of valve body (7), and stopper head (15) is gone up build-in magnet (6), and magnet (6) is fixed a volute spring (9), spring (9) other end be placed in adapter (13) around, logical oil pocket (3) end has side direction oil outlet (5).When unlubricated oil entered valve body chamber (7), because spring (9) elastic force effect makes stopper head (15) be limited in the big chamber of valve body (7) left end, valve rod (4) matched with the valve body lumen, and oil outlet (5) is just in time sealed by the lumen wall.Valve pocket (14) is placed in the outer wall of valve body (2), between valve pocket (14) and the valve body (2) tongue tube (8) is arranged, contact in the tongue tube (8) links to each other with external circuit, oil pressure is pushed valve rod (4) to the right side when lubricating oil flows into the valve body chamber, magnet (6) also to the right, and the interior contact adhesive of tongue tube (8), make external circuit conducting output electric signal, lubricating oil is flowed through the big chamber of valve body (7) to flowline (11) inflow oil site through oil outlet (5), when no oil entered valve-rod cavity (3), spring (9) was with valve rod (4) pop into position, and oil circuit is closed, contact separates in the tongue tube, and external circuit is cut off.Because the center line of oil inlet pipe (1), valve body chamber, valve-rod cavity (3) and flowline (11) is on same straight line, the convection current of this detecting device does well and reacts responsive fast.Adopt closed tongue tube contact, the magnet adhesive, working stability is reliable, and prolong serviceable life.
Claims (4)
1, fuel-displaced detecting device, it is made up of oil inlet pipe (1), flowline (11), valve body (2), valve rod (4) and valve pocket (14), it is characterized in that valve rod (4) one ends become the stopper head (15) that matches with the big chamber of valve body (7) for logical oil pocket (3) other end for expanding, logical oil pocket (3) end side is to oil outlet (5) is arranged, establish magnet (6) on the stopper head (15), establish spring (9) on the magnet (6), between valve pocket (14) and the valve body (2) tongue tube (8) is arranged, the contact in the tongue tube (8) links to each other with external circuits.
2, fuel-displaced detecting device as claimed in claim 1, the center line that it is characterized in that oil inlet pipe (1), logical oil pocket (3), valve body chamber and flowline (11) is on same straight line.
3, fuel-displaced detecting device as claimed in claim 1, it is characterized in that volute spring (9) one ends be placed in adapter (13) around.
4, fuel-displaced detecting device as claimed in claim 1 or 2 is characterized in that oil inlet pipe (1) and flowline (11) are tightened up by double-deck chock plug (10) sealing.
