Number in the figure: 1 oil nozzle, 2 valve switch, 3 oil nozzle protecting covers, 4 adapter sleeves, 5 break valves, 6 secondarys are got on oil nozzle 7 seal covers 8 lower seal 9 guide rods 10 15 handwheels, 16 water inlet pipes, 17 first chambeies, sealing ring 12 springs 13 valve bodies, 14 second chambeies, 18 baffle plates, 19 inner chambers on the sealed loop-pad 11.
Embodiment
Outer switching regulator transformer described in the utility model is got fuel tap, comprise oil nozzle 1, mounted valve switch 2 on the oil nozzle 1, the periphery of oil nozzle 1 is installed adapter sleeve 4, the inner diameter of adapter sleeve 4 is greater than the outer end diameter, offer inner chamber 19 in the inner of adapter sleeve 4, offer internal thread in the inner chamber 19, the periphery of oil nozzle 1 is offered external screw thread, and the external screw thread of the internal thread of inner chamber 19 and oil nozzle 1 cooperates, and adapter sleeve 4 is threaded with oil nozzle 1, valve switch 2 is positioned at inner chamber 19, adapter sleeve 4 outer ends are provided with external screw thread, and the outer end of adapter sleeve 4 is connected with break valve 5 threaded one ends, and the other end of break valve 5 is got oil nozzle 6 with secondary and is threaded.During use, valve switch 2 is in open mode all the time, and promptly oil nozzle 1 is in all the time and gets oil condition, and at this moment, the switching of fuel tap, is rotated handwheel 15 and oil can be emitted when need are got oil by break valve 5 controls, and 15 of reversing handles can cut out break valve 5, and oil sealing is deposited.Valve switch 2 is the nuts that are installed on oil nozzle 1 periphery.
As shown in Figures 2 and 3, break valve 5 can be by valve body 13, guide rod 9, handwheel 15, seal cover 7, spring 12, last sealed loop-pad 10 and last sealing ring 11 connect and compose, offer cavity in the valve body 13, cavity is provided with baffle plate 18 and water inlet pipe 16, water inlet pipe 16 is connected with baffle plate 18 cavity is divided into first chamber 17 and second chamber 14, guide rod 9 is installed on the valve body 13, the axis conllinear of the axis of baffle plate 18 and guide rod 9, one end of guide rod 9 passes outside the valve body 13 and is connected with handwheel 15, the other end of guide rod 9 is connected with seal cover 7, offer annular groove on the seal cover 7, water inlet pipe 16 is positioned at annular groove, the periphery of guide rod 9 is installed sealing ring 11 and last sealed loop-pad 10, last sealing ring 11 is between last sealed loop-pad 10 and valve body 13, the periphery mounting spring 12 of guide rod 9, an end of spring 12 contacts with last sealed loop-pad 10, and the other end of spring 12 contacts with seal cover 7.When break valve 5 is in the pass closed state, as shown in Figure 3, water inlet pipe 16 cooperates with seal cover 7, water inlet pipe 16 is positioned at the annular groove of seal cover 7, at this moment, water inlet pipe 16, seal cover 7 and baffle plate 18 are divided into 14 two the complete independent cavity in first chamber 17 and second chamber with the inner chamber of valve body 13, and be not connected, can prevent effectively that oil is by flowing out in the break valve 5; When need are got oil, rotate handwheel 15, guide rod 9 drives seal cover 7 to be separated with water inlet pipe 16, and at this moment, first chamber 17 and second chamber 14 communicate, and break valve 5 is opened and can normally be got oil.After break valve 5 uses a period of time, last sealing ring 11 can partly be worn and torn, its sealing function to guide rod 9 can descend, but, under the elastic force of spring 12, last sealed loop-pad 10 can push sealing ring 11 fits tightly it all the time with guide rod 9, thereby, can guarantee the upward sealing effectiveness of 11 pairs of guide rods 9 of sealing ring.After break valve 5 uses a period of times, between being threaded of guide rod 9 and valve body 13 gap may appear, still, 12 pairs of seal covers 7 of spring have pretightning force all the time, guarantee seal cover 7 and water inlet pipe 16 sealings closely, thereby, the sealability of break valve 5 further improved.
For further guaranteeing the sealing effectiveness of 16 of seal cover 7 and water inlet pipes, lower seal 8 can be installed in the annular groove of seal cover 7.
