Abstract

The utility model relates to a simple type antifreezing water tap, and pertains to the valve gate. The utility model consists of a body case, an obturating piston, a piston handle. The inner wall of the inlet port in the body case is of the cone sealing surface. The sealing piston is of the cone plate whose taper dimension matches with the inner wall cone sealing surface of the body case, and complies with the piston control handle. The handle rotating shaft is manipulated to connect with the worms of the crust by the piston control handle and adjust the position of the sealing piston and control the flow. In using the water, the sealing piston goes downwards and the water tap opens, and the tap water in the pipeline is discharged through the cavity of the water tap. On the contrary, the sealing piston goes upwards and the water tap turns off, and the cavity is free from pressure and dose not reserve the tap water, and thus gets rid off the possibilities of the water tap getting frozen and destroyed in the severe conditions.

Description

Simple anti-freezing water tap

Technical field the utility model 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 utility model purpose 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 utility model 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.

The utility model simple anti-freezing water tap 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: 1-housing; 2-packed-piston; 3-piston Joystick; Embedded with metal ring in 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; 10-ball 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:

Press shown in the accompanying drawing 2, after making housing 1 blank with resistance to low temperature QT350-22L or QT400-18L casting preferably, gold machining is made trapezoidal thread that housing 1 and rotating shaft 6 top screw threads 7 match, is connected the interface thread 11 of usefulness, the feed-water end inwall conical seal (contact) face that matches with packed-piston 2 with pipe network; Make Joystick rotating shaft 6 shown in the accompanying drawing 4 and Joystick handle 5 with Ni-Cu alloy or aluminum bronze, manganese brass bar; With resistance to low temperature natural rubber or teflon preferably, make the garden taper type packed-piston 2 that path side shown in the accompanying drawing 3 is inlaid with metal ring 4 through mold pressing or injection moulding; Stainless steel ball top pressure spring 9 and wear resistant and rustproof ball 10 that commercial elastic force is suitable.Then above-mentioned component parts is pressed assembling shown in Figure 1, the simple anti-freezing water tap has just been made.During use, only need to be connected the interface thread 11 of this water tap just feasible with the vertical mouth of pipe of tap water pipe network.During water, handle with sleeve 5 moves down packed-piston 2, and water tap is opened; During water, will not move on the packed-piston 2, water tap is closed, and the water tap inner chamber has become not to be stressed and also do not accumulate the cavity of tap water.If needing the water supply pipe of installation water tap is that level is laid, can connect quarter bend earlier at the running water pipe interface of level during installation, this water tap just can have been installed and used equally with vertical water pipe.

The utility model simple anti-freezing water tap has only very simple several Component, and cost is low and practicability is good, as long as the tap water pipe network that connects is not frozen, water tap just freezes never.Really cracked the frozen flimsy difficult problem of water tap under the severe cold condition, be desirable can be at the simple anti-freezing water tap of cold area penetration and promotion.
