Abstract
A tap water pipe automatic vent valve comprises a valve cap and a valve core, the valve cap is mounted outside the valve core in a sleeved mode, the valve core is mainly composed of an upper cover, a valve pipe and a valve plug, wherein the upper cover and the valve plug are respectively arranged on two end openings of the valve pipe, a breather pipe is arranged in the valve pipe in a sleeved mode, a pull spring is arranged in the breather pipe, one end of the pull spring is connected with a pull spring rod fixedly connected to the upper portion of the inner wall of the valve pipe, and the other end of the pull spring is connected with the valve plug. The tap water pipe automatic vent valve is simple in structure, the valve is directly mounted at the tail end of a tap water pipe through a three-way connecting pipe, and automatic and timely air discharging can be achieved after water is used, water level in the tape water pipe can be decreased to be under a freezing layer, water stored in the tap water pipe can be discharged completely, self heat preservation can be achieved, anti-freezing effect is good, manual operation is not needed, and water resource can be saved.
Description
Technical field
The utility model relates to a kind of valve, specifically a kind of running water pipe valve air relief that can realize tap-water pipe defrosting.
Background technique
In vast rural area, general running water pipe all is installed in outdoor, in temperature lower winter, if after having water to be frozen in the running water pipe, not only causes the water difficulty, and serious meeting causes the running water pipe bursting by freezing to leak.There is now the antifreeze facility of a lot of running water pipes to emerge gradually, but they just are incubated for running water pipe itself, water in the anti-water stopping tube is endured cold, or water carried out water conservancy diversion, remaining water in the running water pipe behind the throttle down is emptying, and the heat insulation effect that these measures have is undesirable, some waste water resources, operating method is complicated, can not be accepted and be widely used by vast rural residents.
The model utility content
The utility model is for defective of the prior art, and a kind of good freezing protection effect is provided, and can automatically carry out exhaust to running water pipe, water level is dropped to freeze the following running water pipe valve air relief of layer.
The utility model is by the following technical solutions: a kind of running water pipe valve air relief, comprise bonnet and spool, and bonnet is sleeved on the spool outside, and described spool mainly is comprised of loam cake, valve pipe and valve plug, and loam cake and valve plug are separately positioned on the two-port of valve pipe; Valve pipe internal sleeve is equipped with breathing pipe, and breathing pipe inside arranges an extension spring, and extension spring one end is connected with the extension spring bar that is fixed in valve inner tube wall top, and the other end is connected with valve plug.
Compare with traditional antifreezing measure, this new structure is simple, only need to this valve be directly installed on by the connecting tube of threeway form the tail end of running water pipe, after being finished water, can be automatically, in time exit, not only can freeze below the layer the water level in the running water pipe is dropped to, water in the emptying water pipe, and can realize oneself's insulation, good freezing protection effect, need not increase manual operation, save water resources.
Description of drawings
Fig. 1 is the utility model overall structure schematic diagram.
Among the figure: loam cake 1, extension spring bar 2, bonnet 3, extension spring 4, valve pipe 5, breathing pipe 6, sealing rubber ring 7, rust-preventing film 8, valve plug 9, water intake 10, connecting tube 11, valve plug thickening layer 12, air insulated thermal insulation layer 13.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
This novel disclosed this running water pipe valve air relief comprises bonnet 3 and spool, and bonnet 3 is sleeved on the spool outside.Spool mainly is comprised of loam cake 1, valve pipe 5 and valve plug 9, and loam cake 1 and valve plug 8 are separately positioned on the two-port of valve pipe 5; Valve pipe 5 internal sleeve are equipped with breathing pipe 6, and breathing pipe 6 inside arrange an extension spring 4, and extension spring 4 one ends are connected with the extension spring bar 2 that is fixed in valve pipe 5 upper inside wall, and the other end is connected with valve plug 9, and extension spring bar 2 is fixedly connected with the inwall of valve pipe.Breathing pipe 6 is generally rubber pipe, can play insulation effect.The center portion of loam cake 1 arranges a relief opening A who is communicated with valve core inside.
This bleed valve is communicated with running water pipe by connecting tube 11, and connecting tube 11 is three-way pipe, and the valve plug end of bleed valve is arranged on the connecting tube 11 ports inside relative with water intake 10.
As preferred version: bonnet 3 and connecting tube 11 joints of bleed valve are set with sealing rubber ring 7, and this sealing rubber ring 7 is arranged between bonnet and the connecting tube joint, is sleeved on the outside of valve pipe.
Be provided with rust-preventing film 8 on the end face of valve pipe 5 and valve plug 9 contacting points, not only can be antirust, can also play seal action.
Be provided with valve plug thickening layer 12 on the bottom surface of valve plug 9, this valve plug thickening layer is generally wax, can strengthen sealing.
One drain opening is set respectively on valve pipe and the bonnet, and the drain opening on the valve pipe 5 is the B mouth, and the drain opening on the bonnet is the C mouth.
Using method of the present utility model is: after the installation, after having water to be entered the water intake 10 of connecting tube by tap water, because hydraulic pressure upwards pushes up valve plug, close spool, water is flowed out by another outlet of three-limb tube; After closing aqueduct valve, because water by pumpback, under the effect of reaction force, can pull down valve plug, open spool, like this, the air that is evacuated formation in the running water pipe is discharged by valve.In the process of exhaust, also can flow to the valve pipe along valve plug by some water, these water are discharged from by the drain opening B on valve pipe and the bonnet and C.Because between breathing pipe and the valve pipe space is arranged, breathing pipe is quality of rubber materials, can fully be incubated, the air insulated thermal insulation layer between bonnet and the valve pipe also can be incubated simultaneously, therefore valve body self can realize that the oneself is incubated, prevents that valve body self from enduring cold.
