Abstract
The utility model relates to a refeeding stop valve. The utility model is characterized in that a valve cavity of a valve body forms a star shape, and a valve body wall is provided with a convex hole covered by the screw threads of a convex press cover. A push rod is inserted at the center of the press cover and then fixes a thrust plate, and the end face of the valve cavity parallel to a water outlet fixes the press cover through the screw threads. A valve cavity face of a water inlet is provided with a groove, and a floating ball is arranged in the valve cavity. The utility model solves the problem that a water tap which is not closed after the water supply cuts off can not be automatically closed after the water is supplied again. The utility model has the advantages of simple structure, low cost and convenient assembly and disassembly, and the water tap does not need to be changed.
Description
The utility model relates to the match water supply shut-off valve again of usefulness of a kind of water tap.
The water tap or the water supply valve of resident or industrial building use at present, water tap does not cut out and after supplying water again, causes the flowing water phenomenon serious after cutting off the water.Though, the existing automatic stop valve of similarly cutting off the water on the market, effect is not very optimistic, occurs water leakage phenomenon easily after supplying water again, not only causes water resource waste, and brings harm for building, decoration and indoor other facility goods and materials of resident.
The purpose of this utility model is to avoid the deficiency of above-mentioned technology, and a kind of water supply shut-off valve again that can close automatically when supplying water again is provided.
The purpose of this utility model can reach by the following technical programs: this stop valve comprises water intake, water outlet and the valve body of valve pocket arranged, the valve pocket of valve body be "
" type; have a convex hole that covers with convex gland screw thread at valve body wall; fix a thrust plate after the interspersed gland central authorities of push rod; the valve pocket end-face helical stationary gland arranged side by side; the valve pocket face of water intake has a groove; insert ball float in the valve pocket, and wherein the diameter of ball float is greater than the diameter of intake-outlet with water outlet.
The utility model has following advantage than above-mentioned prior art: because the diameter of ball float is less than the diameter of intake-outlet, and have a groove at the valve pocket face of water intake, make and cutting off the water, when coming water, can close water tap automatically; And this stop valve structure is simple, and is easy for installation, is not subjected to the restriction of water tap position, and selection is extensive, and purposes is wide, not only is used for water supply pipe, also can be used on the pipeline of other industry.
Structure when accompanying drawing 1 is the utility model proper functioning is cutd open figure;
Accompanying drawing 2 is that the structure of the utility model when cutting off the water cutd open figure;
Accompanying drawing 3 is that the structure of the utility model when coming water cutd open figure;
Accompanying drawing 4 is that the structure of the utility model when recovering proper functioning cutd open figure.
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, this stop valve comprises water inlet A, water outlet B and the valve body 1 of valve pocket arranged, the valve pocket of valve body 1 be "
" type, having a convex hole at valve body 1 wall, this convex hole is fixed and is covered with convex gland 3 screw threads, fixes a thrust plate 2 after push rod 4 interspersed gland 3 central authorities, make push rod 4 to slide and exercise in the convex hole, and thrust plate 2 matches with the convex hole; The valve pocket end-face helical stationary gland 5 arranged side by side with water outlet B, the valve pocket face of water inlet A has a groove, inserts ball float 6 in the valve pocket, and wherein the diameter of ball float 6 is greater than intake-outlet (A, diameter B).
As shown in Figure 1, stop valve is a normal state, and water flows into from water inlet A, flows out from water outlet B, and ball float 6 is near the gland 5.
As shown in Figure 2, when cutting off the water, ball float 6 leans on the weight of self to slide to the groove of water inlet A along " U " type valve pocket inwall.
As shown in Figure 3, when cutting off the water the back when supplying water, buoyancy by tap water impulse force and ball float 6 is pushed into the water outlet B place with ball float 6, because the diameter of ball float 6 is greater than the diameter of water outlet B, so ball float 6 is blocked water outlet B, makes water not flow out from water outlet B, no matter whether water tap closes, all can not cause the waste of water resources, more can not cause floods.
As shown in Figure 4, when human hand push one lower push-rod 4, the thrust plate of push rod 4 end faces 2 touches ball floats 6, and ball float 6 is pushed into U die cavity opposite side, and ball float 6 rises near the gland 5 by self buoyancy, and water flows out along water outlet B, makes stop valve recover normal state.
As seen, this stop valve has characteristics esy to use, safe and reliable, suitable family, Related pipeline aspect, the field such as office space and industry is used, and promotion prospect is fine.
