Abstract

The utility model discloses an outdoor antifreezing water valve which can prevent the phenomenon of frost crack or ice blockage of outdoor water pipes in winter. The utility model is characterized in that the valve is composed of an upper valve body and a lower valve body, and a movable valve sheet and a fixable valve sheet in a valve body inner cavity are stacked together; a deflector rod below a catch plate is inserted into a deflector rod slot which is arranged on the upper surface of the movable valve sheet, and the movable valve sheet is poked to open and close the water valve. The fixable valve sheet is clamped in a groove which is arranged on an inner wall opening of the lower valve body, and the fixable valve sheet is also provided with a back water gap. After water is used in winter, a valve handle is switched to a back water position or an antifreezing position, which can cause the packing water in tapping pipes exposed out of the ground to go back into wells. The utility model avoid the ice blockage or frost crack of the water pipes, which saves water resource and expenses of users as well as brings convenience of using water for northern users in winter, and many troubles are reduced.

Description

Outdoor Anti-freezing water valve door

The utility model relates to the Liquid valve device, and the outdoor tap water water pipe winter that particularly is used to prevent northern country is by a kind of outdoor Anti-freezing water valve door of bursting by freezing.

In the winter of northern China, the weather is cold and the ground is frozen, and the time is longer, and particularly the running water pipe in rural area all is mounted in the open air, after using up water, at one section vertical some water of water pipe internal memory, winter, temperature one was to subzero at every turn, the water that is stored in the water pipe will freeze, cause running water pipe to stop up, can't water, even with the running water pipe bursting by freezing, for it is frozen, often take the tap water permanent current continuous, tap water then bleeds off in vain, causes the waste of material resources, financial resources and water resources.

The purpose of this utility model provides and can prevent to be installed in winter outdoor running water pipe by bursting by freezing or the stifled a kind of outdoor Anti-freezing water valve door of ice.

The purpose of this utility model is achieved in that a kind of outdoor Anti-freezing water valve door, form by upper valve body, following valve body and spool, it is characterized in that: affiliated spool is cover one elastic ring on the rotating handle above the dial, the driving lever groove of moving valve plate is enclosed within on the driving lever of dial, in the upper valve body of packing into then; Fixed valve plate snaps in down in the valve body, adds seal ring between upper and lower valve body, links into an integrated entity with screw.

Described spool is to put elastic ring 4 and three seals cushion rubber 2 on the rotating handle 1 on dial 5 tops, have two driving levers 22 to insert in the driving lever groove 21 above the moving valve plates 12 in its lower section, having the one side of positioning groove 24 to aim at upper valve body 3 inwalls at moving valve plate 12 edges has the orientation of ball 6 to pack in the upper valve body 3; The convex tendon 20 on fixed valve plate 13 both sides snaps in down on the valve body 18 inwall mouths in the corresponding grooves, 19 pairs in its three holes and be placed on down on the sealing gasket 14 of valve body 18 bottoms the hole and align.

The inwall middle part of described upper valve body 3 is left and is mutually 120 ° of locating bumps 23, is provided with location ball 6 in inwall bottom, locating bump 23 opposite, places top spring 7 in the hole of location ball 6, and is fixed in this hole by screw 8.Six fixing screw holes 9 are set on the outer disc of upper valve body 3 five equilibrium.

Intake pipe 17 is left in the described bottom of valve body 18 down, backwater mouth 16 and outlet pipe 15, and its position is corresponding with 19 positions, equally distributed three holes on fixed valve plate 13 and the sealing gasket 14.

The utility model compared with prior art, when its advantage is boiling water, as long as rotate 60 ° of rotating handles, water valve is just opened, when the weather is cold and the ground is frozen to winter, use up water, behind the throttle down, change 60 ° toward the opposite direction of driving valve again and just backwater mouth is opened, the water on the ground in the running water pipe, flows in the well by backwater mouth toward refluxing by self gravitation, avoid long-term unlatching in winter water tap to realize antifreeze, both the conserve water resource reduced user's spending again, most importantly made family, rural water water in winter the same with summer convenient.

Below in conjunction with accompanying drawing the utility model is illustrated.
