Embodiment
With reference to accompanying drawing, the slow automatic drainage valve that opens and closes of a kind of pipeline irrigation adjustable-pressure, comprise valve body 8, valve body 8 utilizes bolt 6 and valve body joint 1 to link together by flange plate 4, between flange plate 4, be provided with flange rubber pad 16, in valve body joint 1, be provided with connection supports muscle 5, the central position of connection supports muscle 5 has joint axis hole 18, between connection supports muscle 5, form joint spilled water hole 17, the front end of valve body joint 1 arranges filter screen 3, the rear end of valve body 8 is provided with valve body supporting rib 19, between valve body supporting rib 19, form valve body spilled water hole 20, the central position of valve body supporting rib 19 has valve body axis hole 21, sliding axle 2 is installed in joint axis hole 18 and valve body axis hole 21, valve body axis hole 21 is provided with screw thread 22, coordinate and be provided with leading screw 10 with screw thread 22, leading screw 10 is sleeved on sliding axle 2, a spring bearer plate 23 is fixed in one end of leading screw 10, the other end of leading screw 10 arranges sluicing pressure regulating handle 9, on sliding axle 2, fix a spring dead plate 12, on sliding axle 2, be set with rubber ring fixed plate 14, rubber ring fixed plate 14 is provided with watertight rubber circle 13, rubber ring fixed plate 14 utilizes pin 15 to be fixed on sliding axle 2, between spring dead plate 12 and spring bearer plate 23, spring 11 is set, on the valve wall of the front end of valve body 8, have arcuation leak-off chute 7, the end of leak-off chute 7 is provided with limited post 24.Watertight rubber circle 13 and sliding axle 2 can be free to slide under the adjusting of sluicing pressure regulating handle 9 in valve body 8.
Working procedure of the present utility model is: regulate sluicing pressure regulating handle 9, make the neutral position of watertight rubber circle 13 in leak-off chute 7, and watertight rubber circle 13 can horizontally slip in valve body 8, pressure has regulated.When pipeline internal water pressure exceedes the pressure maximum that drain valve can bear, rubber ring fixed plate 14 and watertight rubber circle 13 can move right along sliding axle 2 directions, in the time that watertight rubber circle 14 arrives leak-off chute 7 rightmost side, under the effect of limited post 24, stop moving right, drain valve stops leaking.When pipeline stops supplying water, when manifold pressure reduces, when the elastic force of spring 11 is greater than water pressure, rubber ring fixed plate 14 and watertight rubber circle 13 can be along sliding axle directions to left movement, drain valve is reopened, water is from joint spilled water hole 17, through leak-off chute 7, leaked into outside pipe-line system by valve body spilled water hole 20 again, in pipeline, hydraulic pressure further reduces, rubber ring fixed plate 14 and watertight rubber circle 13 continue along sliding axle direction to left movement, until spring is in home position, till in pipe-line system, water has been let out.Try water by pipe network system, if can not automatic drainage, then by regulating sluicing pressure regulating handle 9, drive rubber ring fixed plate 14 and watertight rubber circle 13 to be moved to the left, improve reduction length and the elastic force of spring, realize automatic drainage.
