Abstract
The utility model relates to an underground double control antifreezing valve which is used in winter. The utility model is composed of a valve rod, a valve body, and a valve core, wherein, the valve rod and the valve body are matched and are connected through screws; the valve rod is provided with an upper valve core and a lower valve core, the upper valve core is provided with an upper valve opening, and the lower valve core is provided with a lower valve opening; the valve body is provided with a discharge orifice, and the length of the valve rod is longer than 1.5 m. When used, the utility model is arranged in a running water pipe and is buried underground. The actions of the upper and lower valve cores are contrary, and water in the running water pipe flows out of the discharge orifice after stopped in the valve. The utility model has the advantages of good antifreezing effect, strong practicability, simple production, convenient use, etc.
Description
The utility model relates to two control antifreezing valves of the underground use of a kind of running water pipe, belongs to the tap-water pipe defrosting device.
Existing running water pipe valve is generally valve port of a spool, and winter, after closing the water source, water was full of water pipe under pressure when using, so very easily bursting by freezing of running water pipe, and waste is economically used and caused in influence.
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, has two valve ports of two spools on a kind of valve rod and provide, and is embedded in undergroundly, guarantees to use winter not two control antifreezing valves of freezing water pipe.
The purpose of this utility model is achieved in that it comprises valve rod, valve body, valve rod and valve body are connected by spiral, and its structure outline is: valve rod is provided with two spools of arranging up and down, and last valve port is arranged on the upper valve core, lower valve port is arranged on the lower valve core, and valve body is provided with discharge orifice.
The purpose of this utility model can also reach by following technical measures: the length of valve rod is greater than 1.5m.
Model utility has following advantage compared to existing technology:
1, practical, good freezing protection effect.When closing the water source, water is dammed in valve, guarantee that running water pipe is interior anhydrous, even also can freezing water pipe in the winter of severe cold.
2, applied widely, both can be used for the rural area users, can use for town dweller and industrial and mining enterprise again.
3, make simply, easy to use.
The explanation of accompanying drawing drawing:
Accompanying drawing is the utility model structural representation.
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
Among the figure, handwheel (1), valve rod (2), spiral (3), spilled water hole (4), upper valve core (5), lower valve core (6), running water pipe (7), lower valve port (3), spiral shell are buckled (9), are gone up valve port (10), valve wall (11), pipe collar (12), welded tube (13).
The utility model is the two control of the underground usefulness of the running water pipe antifreezing valve that uses a kind of winter.During use it is installed on the running water pipe, is embedded in undergroundly, the long 1.5m of its valve rod (2) also can be according to the length of the climatic characteristic in winter design valve rod (2).Handwheel (1) is arranged at the top of valve rod (2), and handwheel (1) is an one with valve rod (2).Valve rod (2) is positioned at welded tube (13), and the spiral (3) by pipe collar (12) cooperates together with valve body (11), and valve body (11) is provided with discharge orifice (4), and the making method of discharge orifice (4) is to go up punching at valve wall (11), makes it constitute discharge orifice (4).Two spools (5,6) are arranged at the bottom of valve rod (2), spool (5,6) is arranged up and down, last valve is made of upper valve core (5), last valve port (11), upper valve core (5) is positioned at the top of lower valve core (6), last valve port (10) is arranged on the upper valve core, and lower valve port is made of lower valve core (6), lower valve port (8), and lower valve port (8) is arranged on the lower valve core (6), spool (5,6) all adopts nylon, rubber material to make, to guarantee sealing effect.The lower inside of valve wall (11) has spiral shell button (9).
Working principle of the present utility model is: valve is formed the double controlling valve door up and down, and it is opposite that the bidirectional control valve core is promptly gone up the action of lower valve core (5,6), and when upper valve core (5) was opened, lower valve core (6) was closed, and when lower valve core (6) was opened, upper valve core (5) was closed.When opening running water valve, last valve port (10) is plugged, and forms the water pipeline of complete closed.After closing the water source, lower valve core (6) is blocked lower valve port (8), simultaneously upper valve core (5) leaves the running water pipe connection of valve port (10) and this valve back, and the water in the running water pipe (7) is flow to valve by the discharge orifice (4) on the valve wall (11) again in the utility model and is seeped into underground outward by counter the flowing to of static pressure.Guarantee that running water pipe (7) is interior anhydrous, play antifreezing effect.The antifreeze phase closes later and closes valve port (10), opens lower valve port (8) and makes it form the flowing water energy circuit of complete closed.
Claims (2)
1, a kind of two control antifreezing valve comprises valve rod, valve body, and valve rod and valve body are connected by spiral, it is characterized in that valve rod is provided with two spools of arranging up and down, and last valve port is arranged on the upper valve core, and lower valve port is arranged on the lower valve core, and valve body is provided with discharge orifice.
2, two control antifreezing valve according to claim 1, the length that it is characterized in that valve rod is greater than 1.5m.
