Description

Plunger type cooling nozzle

Technical Field

The present invention relates to a cooling nozzle, and more particularly, to a plunger type cooling nozzle.

Background

Nowadays, cooling nozzles are more and more widely used, wherein the use of plunger type cooling nozzles is spread over the construction field, and the existing plunger type cooling nozzles generally have the following problems: clogging is likely to occur during work such as excavation, and the reliability is poor; the flow is not controlled and the requirements of low flow and high flow cannot be met simultaneously.

An effective solution to the problems in the related art has not been proposed yet.

SUMMERY OF THE UTILITY MODEL

To the above technical problem in the related art, the utility model provides a plunger type cooling nozzle, difficult jam and can control out the water flow.

In order to achieve the technical purpose, the technical scheme of the utility model is realized as follows:

a plunger type cooling nozzle comprises a shell and a pipeline, wherein one part of the pipeline enters the shell, one part of the pipeline is located outside the shell, a nozzle is arranged at the tail end of the pipeline outside the shell, a flow control valve is arranged at a position, close to the shell, of the pipeline outside the shell, a radial through hole is formed in the pipeline inside the shell, plugs are symmetrically arranged in the radial through hole, the plugs are connected with a plunger, a spring is sleeved on the plunger, a sleeve is arranged outside the spring, and a water inlet is connected at the tail end of the pipeline inside the shell.

Furthermore, sealing rubber is arranged at the joint of the shell and the pipeline.

Further, the plug is spherical.

Further, the plug is made of a material having a certain deformation amount.

The utility model has the advantages that: the two symmetrically arranged plugs are adopted, so that tight blocking can be realized when no water flow pressure exists, and dust, particles and the like are prevented from entering; in addition, through increasing flow control valve, can control the water flow, avoid needing the trouble that can not satisfy when little flow or large-traffic.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required to be used in the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.

Fig. 1 is a schematic structural view of a plunger type cooling nozzle according to an embodiment of the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art all belong to the protection scope of the present invention.

As shown in fig. 1, according to the embodiment of the utility model provides a plunger type cooling nozzle, including casing 1 and pipeline 2, a part of pipeline 2 gets into within casing 1, a part of pipeline 2 is outside

casing

1, 2 ends of pipeline outside casing 1 are equipped with spout 3, pipeline 2 outside casing 1 is equipped with flow control valve 4 near casing 1 department, pipeline 2 within casing 1 is last to have radial through-hole, the symmetry is equipped with end cap 5 in the radial through-hole, end cap 5 even has plunger 6, the cover is equipped with spring 7 on the plunger 6, spring 7 is equipped with sleeve 8 outward, 2 ends of pipeline within casing 1 even have water inlet 9.

In the preferred embodiment, a sealing rubber is arranged at the joint of the shell 1 and the pipeline 2 to prevent impurities from entering the shell 1.

In the preferred embodiment, the plug 5 is spherical; the plug 5 is made of a material with a certain deformation amount, so that better plugging can be realized.

For the convenience of understanding the above technical solutions of the present invention, the above technical solutions of the present invention are explained in detail through the working principle below.

The utility model discloses the theory of operation: when water does not enter the pipeline or the water inlet pressure is smaller than the elasticity of the spring to the plugs, the two plugs are in close contact with each other to block the holes; when the water inlet pressure of the pipeline is greater than the elasticity of the spring to the plugs, the two plugs are separated by the water pressure, and water flow is sprayed out of the nozzles. The flow control valve installed on the pipeline plays a role in controlling flow so as to adapt to different scenes.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
