Abstract

The utility model discloses an explosion stack connects, it is installed on the water pipe, makes ordinary water pipe become the explosion stack. Base and water piping connection are passed through to explosion stack connects's one end, its other end then with the help of nut and water source for example tap meet. Explosion stack connects is located explosion stack water inlet nut, comprises an inner core, a spring and a shell. The effect of inner core is that the delivery port is plugged up to the inner core when the water pipe bursts, cuts rivers, the inner core is propped up in the effect of spring, prevents that water pipe inner core under the nothing condition of bursting from blockking up the water inlet, the water pressure is adjusted in the effect of shell to support the inner core, fixed spring and inner core. Its water pipe injection water that can prevent effectively to burst, but wide application place outside family, school, mill, warehouse and office building etc. Are indoor.

Description

A kind of explosion-proof pipe joint

Technical field

The utility model relates to water pipe adapter, particularly a kind of Petrochemical Pipe Joints that effectively can prevent explosion water pipe water-spraying.

Background technique

The function of present market water inlet is generally only to guide current, usual not tool anti-water stopping tube explosion function, its quality of product is also uneven, even if water pipe quality is enough good, because the external factor such as Environmental Conditions and service time has uncertainty, there is the possibility of explosion in water pipe, causes occurring that the situation that current direction surrounding is sprayed occurs, and easily causes flood, the person and property loss.At present, although market there is the similar explosion-proof device product preventing explosion water pipe, its complex structure, consumptive material is more, and the effect of anti-water stopping tube explosion is not ideal, installs and uses inconvenience.

Model utility content

The purpose of this utility model to provide a kind of explosion-proof pipe joint, to overcome existing water pipe product not tool anti-water stopping tube explosion function and the existing defect preventing the effect of the explosion-proof device product anti-water stopping tube explosion of explosion water pipe bad, thus effectively can prevent explosion water pipe water-spraying, to avoid causing flood, the person and property loss.

The purpose of this utility model is achieved in that a kind of explosion-proof pipe joint of the utility model, is made up of an inner core, a spring and a shell.Be provided with inner core in described shell, described spring then packs on described inner core.The effect of described inner core is that inner core blocks water outlet when water pipe bursts, and blocks current; Inner core is propped up in the effect of described spring, and anti-water stopping tube is blocking water inlet without inner core under burst conditions; The effect of described shell regulates water entry pressure, and support inner core, fixing spring and inner core.

Further, the utility model preferably adds seal ring between described shell and base.

The utility model is reasonable in design, compact structure, easily installs, easy to use, safe and reliable, effectively can prevent explosion water pipe water-spraying, can be widely used in the indoor and outdoor places such as family, school, factory, warehouse and office building.

Accompanying drawing explanation

Fig. 1, be according to the structural representation that the utility model proposes.

Embodiment

Mark in figure: 1, shell; 2, inner core; 3, spring; 4, seal ring; 5, base.

Below in conjunction with drawings and Examples, structure of the present utility model is further described:

In the drawings, a kind of explosion-proof pipe joint of the utility model is arranged on water pipe, makes common water pipe become explosion stack.One end of described explosion-proof pipe joint is connected with common water pipe by base 5, and its other end then connects with water source such as water tap by nut.

Described explosion-proof pipe joint is positioned at explosion stack water inlet nut, and it is made up of an inner core 2, spring 3 and a shell 1.Be provided with inner core 2 in described shell 1, described spring 3 then packs on described inner core 2.The effect of described inner core 2 is that inner core 2 blocks water outlet when water pipe bursts, and blocks current; Inner core 2 is propped up in the effect of described spring 3, and anti-water stopping tube is blocking water inlet without inner core under burst conditions 2; The effect of described shell 1 regulates water entry pressure, and support inner core 2, fixing spring 3 and inner core 2.

In addition, between described shell 1 and base 5, seal ring 4 is preferably added.

The working principle of described explosion-proof pipe joint utilizes the burst change of the upper and lower joint pressure difference of forward and backward connecting tube of water pipe to design.Before water pipe explosion, current are less through the pressure of described explosion-proof pipe joint, and described spring 3 is in relaxation state, and thus described inner core 2 is motionless, and current enter in water pipe through the hole of described shell 1, flow to water outlet; When after water pipe explosion, current increase through the pressure of described explosion-proof pipe joint, cause hydraulic pressure to push down inner core 2 and move to water outlet direction, block water outlet, close current, thus avoid water pipe explosion water-spraying, reach the object preventing flood from occurring.

Above-described is only preferred embodiments of the present utility model.It should be pointed out that to those skilled in the art, under the prerequisite not departing from the utility model principle, can also make some modification and improvement, this is also considered as belonging to protection domain of the present utility model.

Claims

1. an explosion-proof pipe joint, is characterized in that: it is made up of an inner core (2), a spring (3) and a shell (1); Be provided with inner core (2) in described shell (1), described spring (3) then packs on described inner core (2); The effect of described inner core (2) is that inner core (2) blocks water outlet when water pipe bursts, and blocks current; Inner core (2) is propped up in the effect of described spring (3), and anti-water stopping tube is blocking water inlet without inner core under burst conditions (2); The effect of described shell (1) regulates water entry pressure, and support inner core (2), fixing spring (3) and inner core (2).

2. a kind of explosion-proof pipe joint according to claim 1, is characterized in that: between described shell (1) and base (5), add seal ring (4).
