Abstract

The invention relates to a simple anti-freeze tap water cock, which is formed by frame, sealing piston, and piston control handle, wherein it is characterized in that: the piston control handle can adjust the position of sealing piston to switch cock and control the flux; when using, turning one the sealing piston, the tap water, via level difference, is discharged via the inner chamber of cock; when not using, the sealing piston is turned down, the inner chamber will not store tap water, to avoid freezing and hurting. The invention has simple structure and high reliability.

Description

Simple anti-freezing water tap

Technical field the invention belongs to valve classification, particularly water tap.

Background technique ordinary tap water tap is frozen even housing takes place to freeze break accident be often busy when severe cold.Trace it to its cause, except that water tap itself exists the flaw with the improper workmanship of material, just be to have born the water tap of high hydraulic pressure, be subjected to tap water that the water tap bore seal the power of dilating difficult to the appraisal that volumetric expansion produces when freezing again, in case this power is concentrated at structure organization weakness stress, has caused water tap to be damaged by bursting by freezing.Chinese patent ZL200520023433.5 " rural area outdoor water faucet anti-icer ", though related to the antifreeze problem of water tap, but this apparatus structure is multiple assorted, and its main inventive point is not how to eliminate expansion at the above-mentioned reason that causes pressure-bearing water tap freeze damage, and the anxiety that scratches every boots is seemingly arranged.

Summary of the invention the object of the invention provides a kind of simple anti-freezing water tap, can fundamentally solve the problem of pressure-bearing water tap frozen and easy damage under the severe cold environment condition.

Concrete technological scheme of the present invention is such: a kind of simple anti-freezing water tap, constituted by tap shell, packed-piston, piston Joystick, it is characterized in that: this water tap is realized switch water tap and control flow rate with after water supply pipe is connected with the position of piston Joystick regulation and control packed-piston; During water, packed-piston is opened, and the tap water in the pipeline is emitted through water tap because of water-head; During water, packed-piston is not closed, and the water tap inner chamber then becomes not to be subjected to any pressure also not accumulate the cavity of tap water.

For make this structure for water tap, making can both be simple and easy, described housing, is made by fit dimension requirement gold machining after casting technique is made blank with metallic material again; Described packed-piston is made the circular cone that matches with housing inner conical sealing surface with rubber or plastics through mould-forming; Described piston Joystick is made up of Joystick handle, Joystick rotating shaft two-part, and rotating shaft top is shaped on screw thread and is connected with housing, and lower end and packed-piston are movingly.

The prerequisite precondition of antifreezing faucet is that the material of manufacturing water tap must be antifreeze.For this reason, this programme requires to select suitable made component parts for use by the extreme minimum temperature of this water tap territory of use and environment.

For preventing water tap leakage, manufacturing adds man-hour, should suitably improve the quality of fit of housing and the rotating shaft of piston Joystick, housing inner conical sealing surface and packed-piston; The employing trapezoidal thread that is connected of housing and Joystick rotating shaft.

This water tap is after installing on the water supply pipe, and the circular cone bigger diameter end face of packed-piston is the hydraulic pressure bearing surface all the time.For guaranteeing that switch is flexible under the piston pressurized situation, reliable operation, and improve working life, this programme adopts and establishes cross-drilled hole in the rotating shaft lower end, be connected movingly with the packed-piston that is inlaid with metal ring with built-in spring roof pressure both sides ball type, become the straight line of piston to move the rotational transform of rotating shaft, packed-piston falls when preventing simultaneously that water supply pipe is anhydrous.

Simple anti-freezing water tap of the present invention not only structure is very simple, easy to manufacture, and the reason of frozen damage under the ordinary faucet severe cold environment of eliminating prior art tightly, water tap is opened when discharging water only as the flow channel that does not bear hydraulic pressure, close stop water after, not only without any pressure, and become not have the cavity of ponding in the housing, thereby structurally avoided the possibility that causes water tap to freeze and damage.

Description of drawings Fig. 1 is the simple anti-freezing water tap structural representation; Fig. 2 is the tap shell schematic representation; Fig. 3 is the packed-piston structural representation; Fig. 4 is a piston Joystick structural representation.

Each mark is as follows among the figure: the 1-housing; The 2-packed-piston; 3-piston Joystick; Embedded with metal ring in the 4-piston; 5-Joystick handle; The rotating shaft of 6-Joystick; 7-rotating shaft top screw thread; 8-rotating shaft lower, transverse hole; 9-ball top pressure spring; The 10-ball that is dynamically connected; 11-water tap interface thread

Embodiment elaborates below in conjunction with the mode of execution of accompanying drawing to the simple anti-freezing water tap:

QT350-22L or QT400-18L spheroidal graphite cast iron are the casting material of housing 1 preferably to select resistance to low temperature for use.After blank was cast, the conical seal (contact) face that matches of trapezoidal thread, interface thread 11 and housing 1 that housing 1 matches with rotating shaft top screw thread 7 and packed-piston 2 was made in gold machining; Make Joystick rotating shaft 6 and Joystick handle 5 with Ni-Cu alloy or aluminum bronze, manganese brass bar; With resistance to low temperature preferably natural rubber or teflon be the materials of packed-piston 2, adopt mold pressing or injection moulding to make packed-piston 2, during making and with internal diameter and rotating shaft 6 works metal ring 4 movingly, be embedded in path one side of packed-piston 2 simultaneously; Stainless steel ball top pressure spring 9 and wear resistant and rustproof ball 10 that commercial elastic force is suitable.With the correctly assembling in regular turn of above-mentioned component parts, the simple anti-freezing water tap is just made and has been finished then.During use, only need the vertical mouth of pipe of water tap tipping, but just normal switch has been used at the tap water pipe network.If needing the water supply pipe of installation water tap is that level is laid, for easy to operate, can connect a quarter bend earlier at the running water pipe interface of level, this water tap just can have been installed and used equally with vertical water pipe.

Simple anti-freezing water tap of the present invention only has very simple several spare and accessory parts, cost Low and practicality is good, as long as the tap water pipe network that connects is not frozen, tap just never Freeze. Really having cracked the frozen flimsy difficult problem of tap under the severe cold condition, is desirable Can be at the simple anti-freezing tap of cold district penetration and promotion.
