Description

Rotation type fire extinguishing tap

Technical field

The utility model relates to fire-fighting equipment technical field, specifically, relates to a kind of rotation type fire extinguishing tap.

Background technology

Fire-fighting fire extinguishing hydraulic giant is one of fire-fighting equipment of fire-fighting indispensability, but, due to the limitation of existing fire-fighting fire extinguishing hydraulic giant existence, fireman can only spray water to the scene of a fire by hand-held Fire water syringe outside the scene of a fire, the water that ejection is gone, can only rely on the deadweight of water to be landed, expect that again water spills to surrounding, to reach fire extinguishing object, well-known, the intensity of a fire is generally to vertical spread, if after the combustible ignition of the interior eminence of building, Fire water syringe just cannot be sprayed water to it in run-home, and spray just can not be fallen temperature less than water, is easy to burn down ceiling.That is to say, there is the many defects in water spray dead angle in existing fire-fighting fire extinguishing hydraulic giant.

Summary of the invention

The purpose of this utility model is, provides a kind of rotation type fire extinguishing tap, to solve above-mentioned technical problem.

For achieving the above object, the technical scheme that the utility model adopts is:

A kind of rotation type fire extinguishing tap, is characterized in that: comprise the rotation water jet, central shaft and the water inlet pipe that are flattened cylindrical shape; Two discs of described rotation water jet are former and later two longitudinal sides; On the outer wall of described water inlet pipe, be fixed with annular Ka Tai, the top of water inlet pipe extend into rotation water jet inner chamber from the bottom of rotation water jet; The bottom of described rotation water jet contacts on the end face of Ka Tai; Described central shaft runs through rotation water jet downwards from the center at rotation water jet top, and its bottom is fixedly connected with the lateral frame being fixed on water inlet pipe inwall, and lock by clamp nut on its top; On the arcwall face of described rotation water jet, be provided with several hole for water sprayings.

say further:

Described in the arcwall face of rotation water jet, centered by central shaft, be divided into left cambered surface and right cambered surface, described hole for water spraying comprises the left side hole for water spraying that is arranged in left cambered surface and is arranged on the right side hole for water spraying in right cambered surface, and the number sum of described left side hole for water spraying and right side hole for water spraying is 5 or 7; Described left side hole for water spraying is arranged at the left side of left cambered surface center line, described right side hole for water spraying is arranged at the left side of right cambered surface center line, and the circle center line connecting of each left side hole for water spraying equates to the distance L 2 of right cambered surface center line to the distance L 1 of left cambered surface center line and the circle center line connecting of each right side hole for water spraying.

Described water inlet pipe is connected with connector on bottom.

In the hole that the top of described rotation water jet and central shaft join, be provided with upper sealing washer; In the hole that the bottom of described rotation water jet and water inlet pipe join, be provided with lower sealing washer.

beneficial effect:compared with prior art, the utility model can be put out a fire in the middle of the scene of a fire, to traditional one innovation of putting out a fire in outside, the scene of a fire, in the time that reality is used, only the utility model need be put in the middle of the scene of a fire, connect behind water source, water just can spray from hole for water spraying, simultaneously, the pressure of water impels rotation fire extinguisher to rotate around central shaft, like this, the water of each hole for water spraying ejection will be circumference and strafe, the water of each hole for water spraying ejection just almost forms spherical injection, not only can not leave any dead angle, and, fire-fighting efficiency improves greatly, have a good application prospect.

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is the right view of Fig. 1.

the specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

With reference to Fig. 1-Fig. 3, rotation type fire extinguishing tap described in the utility model, comprise the rotation water jet 1, central shaft 2 and the water inlet pipe 4 that are flattened cylindrical shape, be connected with rotation described in connector 5 on described water inlet pipe 4 bottoms, described connector 5 is general water pipe joint.

Two discs of described water jet 1 are former and later two longitudinal sides; On the outer wall of described water inlet pipe 4, be fixed with annular card platform 6, the top of water inlet pipe 4 extend into rotation water jet 1 inner chamber from the bottom of rotation water jet 1; The bottom of described rotation water jet 1 contacts on the end face of card platform 6; Described central shaft 2 runs through rotation water jet 1 downwards from the center at rotation water jet 1 top, its bottom is fixedly connected with the lateral frame 8 being fixed on water inlet pipe 4 inwalls, lateral frame 8 be two with the perpendicular plate body of the internal diameter of water inlet pipe 4, symmetry is fixedly installed on the both sides of central shaft 2 bottoms, to 2 fixations of central shaft, meanwhile, can not make the cross-sectional area of water inlet pipe 4 be affected.Lock by clamp nut 3 on the top, top of described central shaft 2; On the arcwall face of described rotation water jet 1, be provided with several hole for water sprayings.

Described in the arcwall face of described rotation water jet 1, centered by central shaft, be divided into left cambered surface and right cambered surface, described hole for water spraying comprises the left side hole for water spraying 11 being arranged in left cambered surface and is arranged on the right side hole for water spraying 12 in right cambered surface, and described left side hole for water spraying 11 is 5 or 7 with the number sum of right side hole for water spraying 12; Described left side hole for water spraying 11 is arranged at the left side of left cambered surface center line, described right side hole for water spraying 12 is arranged at the left side of right cambered surface center line, and the circle center line connecting of each left side hole for water spraying 11 equates to the distance L 2 of right cambered surface center line to the distance L 1 of left cambered surface center line and the circle center line connecting of each right side hole for water spraying 12.

In order to improve the sealing of rotation water jet 1, avoid the situation of leaking to occur, in the hole that the top of described rotation water jet 1 and central shaft 2 join, be provided with upper sealing washer 71; In the hole that the bottom of described rotation water jet 1 and water inlet pipe 4 join, be provided with lower sealing washer 72.

In reality when operation fire extinguishing, for guarantee rotation water jet 1 in the time rotating, be not subject to around the stopping of foreign material, should be in outer cup of the present utility model a bearer bar, rotation water jet 1 and foreign material are around kept apart.

Connect behind water source by connector 5, water is entered the inner chamber of rotation water jet 1 by water inlet pipe 4, and via each hole for water spraying ejection, under the reaction force of hole for water spraying water outlet, can form moment, this moment will make rotation water jet 1 rotate and (be noted that around central shaft 2, total vectorial force of the reaction force of each hole for water spraying should equal zero, otherwise rotation water jet 1 just has very big bang, namely, rotation water jet 1, outside central shaft 2 rotations, can not have other relative motions again).Like this, the water of each hole for water spraying ejection will be circumference to be strafed, and the water of each hole for water spraying ejection just almost forms spherical injection, not only can not leave any dead angle, and fire-fighting efficiency improves greatly.
