Abstract

The utility model discloses a self-closing water pipe outer connector which is composed of a sub connector, a female connector and a sealing plate, wherein the sub connector is straight-pipe-shaped, and the external diameter of the sub connector is large in one end and small in another end; a screw thread is formed in an inner hole, and an external thread is formed at the end with the small external diameter; the sealing plate is arranged on the end face of the small end of the sub connector, and an ejector pin is arranged on the sealing plate and extends into the inner hole of the sub connector; the female connector is also straight-pipe-shaped, the external diameter of the female connector is consistent with the large end of the sub connector, the internal diameter of the female connector is large in one end and small in another end, and internal threads are formed at the large end and the small end; the internal thread at the large end of the female connector is matched with the external diameter at the small end of the sub connector, and the internal thread at the small end of the female connector is the same with the internal thread of the sub connector in size. The self-closing water pipe outer connector is used for being connected with a water tap. When the water tap is damaged and needs to be dismounted, a tap water total valve does not need to be closed, and the self-closing water pipe outer connector can automatically close a water source so as to provide convenience for dismounting and mounting of the water tap. The self-closing water pipe outer connector is convenient to use and safe and reliable.

Description

A kind of self-closing water male union
Technical field
The utility model relates to a kind of hydraulic engineering accessory, specifically a kind of self-closing water male union.
Background technique
Before a kind of self-closing water male union of the utility model is made, there is not yet report and the use of identical innovation and creation.
Water is Source of life.No matter modern society is cities and towns or rural area, people's water all be unable to do without tap water, the conveying of tap water relies on water pipe, and as the water pipe adapter of one of main accessory in hydraulic engineering, be divided into spigot and socket, water pipe spigot Main Function is to extend length of pipe, the effect of water pipe socket is except extending length of pipe, most important effect is being connected for water tap and water pipe, water tap is attrition component, be easy to damage, in the time that certain water tap damages replacing water tap, tap water main valve must cut out and cuts off the water supply, otherwise cannot dismantle water tap, but water outlet and the use of other water taps are so just affected, the tap water that likely also can affect other people uses.
Summary of the invention
The purpose of this utility model is to provide a kind of self-closing water male union, damages and changes when water tap at water tap, and without closing tap water main valve, self-closing water male union can be closed water source voluntarily, like this, and just dismounting and change water tap easily.
The purpose of this utility model is achieved through the following technical solutions: a kind of self-closing water male union, it is characterized in that, it is made up of sub-joint, female joint and sealing plate institute, described sub-joint is straight tube-like, and its large one end, external diameter one end is little, and endoporus is shaped with screw thread, sub-joint small end outer radius is shaped with outside thread, on sub-joint small end end face, a sealing plate is set, is provided with a thimble on sealing plate, thimble stretches in sub-joint endoporus; Female joint is all straight tube-like, and its external diameter is consistent with the large end of sub-joint, and large one end, internal diameter one end is little, is all shaped with internal thread, and the large end internal thread of female joint and sub-joint small end outside thread match, female joint small end internal thread and sub-joint internal thread same size.
Adopt a kind of self-closing water male union of the utility model to carry out connecting tap, in the time that water tap is screwed into sub-joint, just thimble is backed down together with sealing plate, make water route unimpeded, in the time that water tap damage is unloaded, under tap water pressure effect, sealing plate is pressed on sub-joint small end end face, has shut water route, and water just can not flow out from joint, facilitate removing and installing of water tap, easy-to-use, safe and reliable.
Brief description of the drawings
Fig. 1 is a kind of self-closing water male union of the utility model straight pipe type structural representation.
Fig. 2 is a kind of self-closing water male union of the utility model bent tube type structural representation.
In Fig. 1, Fig. 2: 1. sub-joint, 2. sealing plate, 3. female joint, 4. thimble.
Embodiment
Below in conjunction with accompanying drawing 1, the utility model self-closing water male union is further described:
In Fig. 1 embodiment, self-closing water male union is straight pipe type, be made up of sub-joint 1, female joint 3 and sealing plate 2, endoporus is shaped with screw thread, and sub-joint 1 large one end, external diameter one end is little, sub-joint 1 small end outer radius is shaped with outside thread, on sub-joint 1 small end end face, a sealing plate 3 is set, sealing plate 3 is circular, and its diameter is slightly less than sub-joint 1 end diameter, on sealing plate 3, be provided with a thimble 4, thimble 4 stretches to sub-joint 1 endoporus; Large one end, internal diameter one end of female joint 3 is little, is all shaped with internal thread, and the large end internal thread of female joint 3 and sub-joint 1 small end outside thread match, female joint 3 small end internal threads and sub-joint 1 internal thread same size.
In Fig. 2 embodiment, self-closing water male union is bent tube type, formed by sub-joint 1, female joint 3 and sealing plate 2, described sub-joint 1 is tube shape, and sub-joint 1 structure is identical with Fig. 1's, and female joint 3 is bent tube type, its large one end, internal diameter one end is little, all be shaped with internal thread, the large end internal thread of female joint 3 and sub-joint 1 small end outside thread match, female joint 3 small end internal threads and sub-joint 1 internal thread same size.
The structural principle of a kind of self-closing water male union of the utility model, female joint 3 can also be three-way pipe, in actual applications, between sealing plate 2 and sub-joint 1 small end end face, sealing material can be set, and ensures that sealing is better.
It needs to be noted, the mode of above-described embodiment only limits to describe embodiment, but the utility model is confined to aforesaid way incessantly, and those skilled in the art can modify easily not departing from scope of the present utility model accordingly, therefore scope of the present utility model should comprise principle that the utility model discloses and the maximum magnitude of new feature.
