Technical Field

The invention relates to a spray cap, in particular to a spray cap capable of adjusting the opening pressure of a nozzle, and belongs to the field of agricultural machinery, food machinery or mining machinery.

Background

The spraying operation is widely applied to the fields of cleaning, fire fighting, chemical engineering, pharmacy, surface spraying, ink-jet printing, plant protection, food preservation, drying and the like. According to different principles, the spraying operation mainly comprises ultrasonic spraying, pressure spraying, centrifugal spraying and the like.

In pressure spraying, the spray pressure has a significant effect on droplet diameter, coverage, penetration, etc. Depending on the spray pressure, the pressure spray can be classified into a high pressure spray and a low pressure spray, and accordingly, the nozzle can be classified into a high pressure nozzle and a low pressure nozzle. Therefore, in pressure spraying, various types of nozzles can only be used in specific situations, and proper atomization effect cannot be obtained by adjusting the opening pressure according to different operation objects and different spraying requirements of the same operation object, so that the problems of poor universality, low application range and the like exist.

Disclosure of Invention

In view of the above-mentioned disadvantages of the existing pressure nozzles, the present invention provides a new nozzle product which can be used to obtain a suitable atomization effect (droplet diameter, coverage, penetration effect) and high versatility by timely and convenient adjustment of the nozzle opening pressure according to different operation objects or different spraying requirements of the same operation object.

In order to solve the problems, the invention is realized by the following technical scheme:

The utility model provides a can be used to adjust nozzle opening pressure spout the cap, by spouting cap main part (1) and sealing ring (2) constitute, its characterized in that: the main body of the spray cap is a stepped cylinder, the diameter of a small-end cylinder of the stepped cylinder is equal to the inner diameter of the compression spring (3), the outer surface of a large-end cylinder is provided with threads and a groove for installing a sealing ring, a regular hexagonal blind hole is milled inside the large-end cylinder, the small-end cylinder is used as a rotating shaft on the end surface of a cylinder at the other end of the blind hole, and atomization micropores are uniformly distributed on the end surface of the cylinder at the other end; the spray cap main body is arranged in an inner hole at the outlet end of the nozzle seat (4) through threads, the sealing plug (5) is arranged at the liquid inlet end of the nozzle seat through a compression spring, and the sealing ring is a 2-3 circular ring which can only compress plastic or nylon materials.

The invention has the beneficial effects that: the utility model provides a can be used to adjust nozzle opening pressure spout cap, can spout the meshing length of cap and nozzle holder outlet end screw thread through the adjustment according to the different spraying requirements of different operation objects or same operation object, changes the compression length (rigidity) of spring, and then adjusts the opening pressure of nozzle, reaches the function that changes atomization effect, has advantages such as simple structure, pressure regulating convenience, novel practicality, dependable performance.

FIG. 1 is a schematic diagram of a spray cap that can be used to adjust the opening pressure of a spray nozzle.

Detailed Description

The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description serve to explain the principles of the invention.

As shown in the attached drawings, the spray cap capable of adjusting the opening pressure of the nozzle consists of a spray cap main body (1) and a sealing ring (2), and is characterized in that: the main body of the spray cap is a stepped cylinder, the diameter of a small-end cylinder of the stepped cylinder is equal to the inner diameter of the compression spring (3), the outer surface of a large-end cylinder is provided with threads and a groove for installing a sealing ring, a regular hexagonal blind hole is milled inside the large-end cylinder, the small-end cylinder is used as a rotating shaft on the end surface of a cylinder at the other end of the blind hole, and atomization micropores are uniformly distributed on the end surface of the cylinder at the other end; the spray cap main body is arranged in an inner hole at the outlet end of the nozzle seat (4) through threads, the sealing plug (5) is arranged at the liquid inlet end of the nozzle seat through a compression spring, and the sealing ring is a 2-3 circular ring which can only compress plastic or nylon materials.

When the pressure of liquid in the pipeline is larger than the elastic force of the spring, the nozzle is opened to carry out spraying operation; when the atomizing effect of the nozzle cannot meet the operation requirement and the opening pressure of the nozzle needs to be changed, the meshing length of the external thread of the spray cap and the internal thread of the nozzle holder can be adjusted, so that the compression length (rigidity) of the spring is changed, the opening pressure of the nozzle is adjusted, and the purpose of changing the atomizing effect is achieved.

The above embodiments do not limit the present invention in any way, and all technical solutions obtained by taking equivalent substitutions or equivalent changes fall within the scope of the present invention.
