Description

A kind of solid foam fire gun

Technical field

The utility model relates to fire-extinguishing apparatus, and particularly one can spicing forming type fast, and the solid foam fire gun that water-out manners changes.

Background technology

Current foam-making branch is in order to ensure that sealing mostly is unitary design, simultaneously in order to ensure that foam mixing liquid ejection effect needs to increase a pipe inner convex platform at solid foam placement section and jet pipe convergence part, but boss herein has often caused solid foam to block permeable mouth, and then affect jeting effect; There is length simultaneously, weight is difficult to control, foams mix flow quantity and the single problem of foaming degree.

Note: mention in literary composition that 90 degree of rotational lock joints refer to patent document: ZL201420186345.6.

Summary of the invention

The utility model is for above-mentioned technical problem, and proposing one can spicing forming type fast, and the solid foam fire gun that water-out manners is modifiable.

For reaching above object, be achieved through the following technical solutions:

A kind of solid foam fire gun, comprising: solid foam rod and the foam spray canister of docking with solid foam rod;

Solid foam rod comprises: the solid foam placing tube of holding solid foam and be arranged at solid foam placing tube one end for the snap joint with cross current; The solid foam placing tube other end is docked and connected by 90 degree of rotational lock joints and foam spray canister one end;

By butt end is initial is disposed with path supercharging spout and turbidity current device with solid foam rod in foam spray canister; Reserved one end axial cavity between supercharging spout and turbidity current device, and foam spray canister is positioned at above-mentioned axial cavity position outer wall is processed with the air admission hole be communicated with axial cavity;

As preferred structure, it is inner that path supercharging spout is detachably assemblied in foam spray canister, and the opening of path supercharging spout selects center to process cross mouth or round mouth;

As preferred structure, turbidity current device selects net type turbidity current device or ripple flow spoiler.

Adopt the utility model of technique scheme, water enters from solid foam rod with cross current end, through solid foam placing tube, form foam mixing liquid, then foam spray canister is entered by foam spray canister and solid foam rod butt end, first by path supercharging spout, the mouth offered due to path supercharging spout is less, and then foam mixing liquid hydraulic pressure increases flow velocity increase, axial cavity position like this between path supercharging spout and turbidity current device just defines negative pressuren zone, now air imports by air admission hole, the air entered and foam mixing liquid are at the abundant mixed foaming in turbidity current device place, then sprayed by the other end of foam spray canister.

Wherein, supercharging spout detachable, is convenient to change the different supercharging spout of opening form, and then affects foam mixing liquid flow and foaming degree herein;

Solid foam placing tube is docked with foam spray canister by 90 degree of rotational lock joints, and docking ensure that sealing fast simultaneously, and effectively shortens single-piece length.

To sum up, the utility model has following advantage: use snap joint to connect, connection speed is fast, and good seal performance, by two sections of splicings, can effectively control single-piece length, be easy to carry, supercharging spout adjustable is convenient to choose the most applicable jeting effect.

Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to technological means of the present utility model can be better understood, and can be implemented according to the content of description, and can become apparent to allow above and other object of the present utility model, feature and advantage, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.

In figure: 1, solid foam rod, 1.1, snap joint, 2, foam spray canister, 2.1, air admission hole, 3,90 degree of rotational lock joints, 4, solid foam placing tube, 5, supercharging spout, 6, turbidity current device, 6.1, axial cavity.

Detailed description of the invention

A kind of solid foam fire gun as shown in Figure 1 to Figure 3, comprising: solid foam rod 1 and the foam spray canister 2 of docking with solid foam rod 1;

Solid foam rod 1 comprises: the solid foam placing tube of holding solid foam 4 and be arranged at solid foam placing tube 4 one end for the snap joint 1.1 with cross current; Solid foam placing tube 4 other end is docked and connected by 90 degree of rotational lock joints 3 and foam spray canister 2 one end;

By 1 butt end is initial is disposed with path supercharging spout 5 and turbidity current device 6 with solid foam rod in foam spray canister 2; Reserved one end axial cavity 6.1 between supercharging spout 5 and turbidity current device 6, and foam spray canister 2 is positioned at above-mentioned axial cavity 6.1 position outer wall is processed with the air admission hole 2.1 be communicated with axial cavity 6.1;

As preferred structure, it is inner that path supercharging spout 5 is detachably assemblied in foam spray canister 2, and the opening of path supercharging spout 5 selects center to process cross mouth or round mouth;
