1. (1), a kind of spiral hollow frost valve comprise 1 valve gap, 2 valve gap walls, 3 caping middle part circular hole 4 inside threads 5 valve gap rubber cushions 6 upper water pipe thread 7 frost valve top water pipes 8 spools 9 spools outside trapezoidal thread 10 valve inner core thread grooves 11 spools bottom control water column plug, 12 water inlets, 13 elastic mounting axles, 14 rubber cushions, 15 octagon valve cylinders, 16 valve cylinder upper outer edge screw threads, 17 valve cylinder inner trapezoidal threads, 18 valve cylinder lower tube joints(2), valve gap 1 is that interlock by inside thread 4 and valve cylinder upper edge screw thread 16 tightens together, and plays the spatial rotation of control spool in design, reaches the purpose that discharges water and close water.Guan Shuihou, the above ponding of valve is discharged from the slit between spool top and the valve gap rubber cushion 5 through crack, circular hole 3 limit, caping middle part.(3), valve cylinder 15 is put in place pipeline about connecting, realize discharging water Guan Shui and the ponding of getting rid of in the above standpipe of valve by the interlock control spool 8 of upper outer edge screw thread 16 and valve gap inner thread 4.(4), spool 8 is by the interlock of outside screw 9 and valve cylinder inside thread 17, and it is rotated according to scope of design, change counterclockwise, water flows in the upper tube by the spool central space, change clockwise, spool bottom control water column plug 11 is blocked the screwed pipe joint 18 of valve cylinder bottom, cuts off the water source, bottom.Spool moves down, and between its top and the valve gap space has been arranged, and the ponding in the uprise of frost valve top is discharged immediately, forms blank pipe, realizes antifreeze purpose.(5), rotate and when the dewatering outlet is opened, to have closed water-leaking hole, closed the dewatering outlet and opened water-leaking hole.The valve gap of this product, valve cylinder, spool rotate mutual restriction, and closely linked is reasonably combined, reaches optimal effect.
