Embodiment
Figure of description is the optimal way that the utility model is implemented, and describes the utility model in detail below in conjunction with accompanying drawing.
As shown in Figure 1: the utility model is by turn-knob 1, a kind of antifreezing valve, comprise turn-knob 1, valve rod 2, gland 3, valve body 5, seal ring, it is characterized in that: at the end assembling turn-knob 1 of valve body 5, valve rod 2, gland 3, first seal ring 4, the other end at valve body 5 assembles second seal ring 7 and spool connecting head 8, spool connecting head 8 links together with valve body 5, end assembling at valve rod 2 stops up 6, the other end of valve rod 2 and turn-knob 1 link together, middle part suit first seal ring 4 and the gland 3 of valve rod 2, one end of gland 3 is screwed onto with valve body 5, gland 3 the other ends are screwed onto with turn-knob 1, be provided with the valve body die cavity in the valve body 5, the valve body die cavity is T-shaped die cavity, is provided with valve rod 2 in the valve body die cavity, and valve rod 2 is joined work with the valve body die cavity; Described spool connecting head 8 middle parts are provided with hexagon nut, the hexagon nut both sides of spool connecting head 8 are provided with male-pipe, wherein an end male-pipe extends and undergauge formation spool, and the spool end assembles second seal ring 7 and cooperates with the valve body die cavity, and the spool termination cooperates with obstruction 6; Described gland 3 is a tubular shape, and axially the middle part is provided with annular boss, and the both sides of annular boss are provided with outside thread, and wherein Yi Bian outside thread cooperates with valve body 5, and wherein the outside thread of another side cooperates with turn-knob 1; Described obstruction 6 is a hemisphere, is provided with mushroom-like head cavity in the center portion, and the mushroom-like head cavity in the obstruction cooperates with the mushroom-like head 25 on the valve rod 2.
As shown in Figure 2: valve body 5 is T-shaped two siphunculus body, in the valve body 5 is T-shaped die cavity, the side at valve body die cavity middle part is provided with female union 52, the upper end portion of valve body die cavity is an internal thread pore 51, internal thread pore 51 is joined work with the male connector on the gland 3, the underpart of valve body die cavity is a female union 53, and female union 53 cooperates with spool connecting head 8.
As shown in Figure 3: described valve rod 2 upper end portions are first cylindrical body 21, cylindrical 21 bottoms are boss shoulder section 22, the bottom of boss shoulder section 22 is provided with second cylindrical body 23 of suit first seal ring 4, the underpart of valve rod 2 is provided with stops up boss 24, stop up boss 24 underparts and be provided with mushroom-like head 25, assembling stops up 6 on the mushroom-like head 25, stops up 6 and cooperates with mushroom-like head 25.
The utility model working principle: when rotating turn-knob 1, promoting valve rod 2 moves upward, the lower end of valve rod 2 is stopped up 6 and is moved up with valve rod 2, opened the water inlet of the underpart of valve, water enters valve body 5 from water inlet and flows, and first seal ring 4 at valve rod 2 middle parts is pushed down boss when valve opening is big, in order to avoid when fluid pressure is big in the pipeline, liquid overflows from the gap location of valve rod 2 with gland 3, also guarantees the movement velocity appropriateness of valve rod 2.During valve closing, valve rod 2 moves downward, and the lower end of valve rod 2 and stop up 6 and move down with valve rod 2 is stopped up 6 water inlets with the underpart and blocked, and cuts off the liquid in the pipe.If valve is closed, the hydraulic pressure of valve water inlet disappears when stopping to supply water.Water beyond the water outlet presses down the obstruction 6 of valve rod 2 lower ends under the effect of atmospheric pressure, opens valve, and the water in the valve outlet pipe arrives in the valve water intake water pipe in addition by valve return.If supply water suddenly again after cutting off the water, hydraulic pressure upwards pushes up first seal ring 4, makes valve closing, and it is excessive to avoid water to take place.
More than explanation is just illustrative for the utility model; and nonrestrictive, those of ordinary skills understand, under the situation of the spirit and scope that do not break away from claim and limited; can make many modifications, variation or equivalence, but all will fall within the protection domain of the present utility model.
