Abstract
The utility model provides a manually reset two position and three-way electromagnetic change valve. The manually reset two position and three-way electromagnetic change valve is composed of a valve body, a sliding valve installed inside the cavity of the valve body, an electromagnet installed on one end of the valve body, an end cover installed on the other end of the valve body, and a reset button. One inlet and two outlets are arranged on the valve body. After the electromagnet acts, when a power supply is disconnected, the sliding valve can not automatically reset, and the sliding valve needs to be pushed by the reset button to realize resetting. Thereby, the equipment of an accumulator, a charger, etc. is not needed to be arranged, and cost is reduced.
Description
The utility model belongs to and is used for the improvement that passing through on the motor changes the valve that working fluid controls.
General two-position three way solenoid directional control valve is and automatically resets at present; when it is used for diesel engine oil circuit protective system; electromagnet action back machine oil flows into oil return trap or fuel tank; the oil pump oil-break; but can hard stop because of the effect of inertia diesel engine but run slowly; this moment is for preventing automatically reseting of valve; electromagnet must keep energising greater than one minute; must dispose storage battery power supply for this reason; and fixtures such as charger, time delay relay, auxiliary reclay need be arranged, thus make the device of oil circuit protective system many, the cost height; the installation and maintenance difficulty, versatility is poor.
The purpose of this utility model provides a kind of two-position three way solenoid directional control valve of hand reset.
The utility model is the improvement to existing two-position three way solenoid directional control valve, it has a valve body that has a filler opening and two oil outlets on it, the thick cylindrical slide valve in thin two ends in the middle of in valve body, being equipped with one, in the endoceliac groove of valve, seal ring is housed, one end of valve body is equipped with electromagnet coil, electromagnet core is installed in the electromagnet coil, and end cap with holes in the middle of the other end of valve body is fixed with is equipped with in the end cap and makes guiding valve hand reset button.
Because the utility model adopts hand reset; need not dispose devices such as storage battery, charger, relay; be applied in the diesel engine oil circuit protective system; can make the cost of protective system reduce by 3/4; and on second-hand machine, install easily; easy to maintenance, the power supply applicability is strong, all can be general from the diesel engine of any types of 50 horsepowers to 800 horsepowers.
Accompanying drawing has provided concrete structure of the present utility model.Longitudinal sectional view of the present utility model when Fig. 1 is the diesel engine normal working; Fig. 2 is a diesel engine oil-break state longitudinal sectional view of the present utility model; Fig. 3 is the A-A sectional drawing among Fig. 1.
The embodiment that the utility model is applied to diesel engine oil circuit protective system is; filler opening (5) is connected with the oil outlet tube of oil strainer; oil outlet (6) is connected with the return tube of oil return trap (or fuel tank), and oil outlet (7) is connected with the oil inlet pipe of Injection Pump.When diesel engine normally moved, diesel oil entered the valve body chamber by filler opening (5), and oil outlet this moment (6) is closed by valve body (4), and diesel oil enters oil pump through oil outlet (7).When barrier causes in the oil circuit pressure low for some reason; electromagnet coil (9) is switched on power supply; with electromagnet core (10) adhesive; promotion guiding valve (4) cuts out oil outlet (7) and opens oil outlet (6); make diesel engine enter the state of running slowly, this moment is if disconnect electromagnet power supply, owing to lack automatic reset mechanism; guiding valve (4) still keeps this state, until shutdown.During if will reset, press the reset button (1) that is installed in the end cap (2), make it promote guiding valve (4) and close oil outlet (6) and open oil outlet (7) with hand.Respectively there is an annular groove at two ends in valve body (3) chamber, and O-ring seal (8) is housed in the groove.
Claims (1)
1, a kind of hand reset two-position three way solenoid directional control valve, comprise the valve body (3) that has a filler opening (5) and two oil outlets (6), (7) on it, the thick cylindrical slide valve (4) in thin two ends in the middle of being equipped with on the valve body (3), in the groove in valve body (3) chamber seal ring (8) is housed, one end of valve body (3) is equipped with electromagnet coil (9), electromagnet core (10) is installed in the electromagnet coil (9), it is characterized in that: end cap (2) with holes in the middle of the other end of valve body is fixed with is equipped with reset button (1) in end cap (2).
