Embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model mainly is made up of valve body 1, temperature controlled valve core assembly 2, Returnning spring 3, oil filter joint 4, oil strainer 5, oil-break spool 6, valve seat 8, pneumatic piston 9, O shape circle 10, screw 11, gland 12, differential pressure switch 13, O shape circle 14, O shape circle 15, the first valve body chamber 16, chamber, the second valve body chamber 17 etc.
The utility model mainly adopts spring 3 to be loaded in the first valve body chamber 16, one end withstands at the bottom of 16 holes, the first valve body chamber, the other end withstands oil-break spool 6, oil-break spool 6 the other ends are equipped with pneumatic piston 9, between oil-break spool 6 and the pneumatic piston 9 valve seat 8 is housed, valve body 1 is provided with O shape circle 7 with valve seat 8 junction planes, seals.Gland 12 is fixed on the valve body 1, and valve body 1 is provided with O shape circle 10 with gland 12 junction planes, seals.Temperature controlled valve core assembly 2 is screwed in the second valve body chamber 17, and valve body 1 is provided with O shape circle 14 with temperature controlled valve core assembly 2 junction planes, seals.Differential pressure switch 13 is screwed into valve body 1, and oil strainer 5 is connected with valve body 1 by oil filter joint 4.O shape circle 15 is set between described valve body 1 and in-line, seals.
Working principle of the present utility model and working procedure:
1, the oil circuit control signal (pressure signal) of main frame row mouth enters multifunction integrated valve from the E mouth, and control oil-break spool 6 is opened and closed, and sees (Fig. 1).When the E mouth had pressure, spool was opened, and oil circuit is opened, and when the disappearance of E mouth pressure, spool is closed under spring force and oil pressure effect, and oil circuit is closed, and plays the function of control oil channel Push And Release.
2, the oil that comes from deaerator enters multifunction integrated valve from A, sees (Fig. 2).By heat-operated valve core 2 oil content is become two-way, the one road goes out into from the B mouth, and cooler, another road enter oil strainer by the heat-operated valve core, see (Fig. 2, Fig. 3).Cold oil through supercooler enters multifunction integrated valve from the C mouth, enters oil strainer again and sees (Fig. 2, Fig. 3).The heat-operated valve in-core has a thermosensitive element, according to the height of temperature, changes channel sized, changes by the oil of cooler and the ratio of cold oil not, makes temperature remain on a stable scope, plays the effect of constant temperature.
3, differential pressure switch 13 directly is loaded on the multifunction integrated valve body, sees (Fig. 4).Accept oil strainer oil-feed and fuel-displaced pressure signal respectively by the inner passage.When the setting value of oil strainer turnover oil pressure difference above differential pressure switch, differential pressure switch just sends alarm signal.
4, oil strainer 5 directly is loaded on the multifunction integrated valve body, sees (Fig. 4).To filter the clean oil in back by the inner passage, and deliver to oil-break spool 6 and see (Fig. 3).Enter main frame from the D mouth then.
The utility model major function is: 1, start, the shutdown of energy random group, in time open, cut off oil circuit; Guarantee unit can normal fuel injection when start, in time oil circuit is cut off when shutting down; Do not have unnecessary long-pending oil in the unit, make when unit starts once more brisk.2, according to the delivery temperature of unit, control sprays into the temperature of unit oil, and the delivery temperature of unit is controlled in the stable scope.3, directly be loaded on oil strainer on the valve body surface oil strainer seat, can tackle the impurity in the oil, the oil of cleaning is supplied with main frame.4, the impurity when the oil strainer interception reaches some, and resistance increases, and its inner differential pressure switch can send the resistance large-signal, and oil strainer is changed in prompting.
