Description

TECHNICAL FIELD

[0001] The utility model relates to a spraying equipment field especially relates to a backflushing nozzle. BACKGROUND

[0002] The nozzle has wide application in many fields, such as spraying dust fall and irrigation etc., and the nozzle is often intermittent operation in the use process.In this case, the nozzle of long-term use can be limited gradually due to rust, scale or external ash into the nozzle, and finally cause the nozzle to be blocked.

[0003] In view of the above situation, the processing mode in the prior art is usually to use a simple through stick type device to dredge, but the internal structure of the nozzle cannot be cleaned, or the nozzle is disassembled for thorough cleaning or replacement, but this mode has complicated working procedure or causes production cost to increase. INVENTION CONTENTS

[0004] The utility model aims at overcoming the prior art's shortcomings, and provides a backflushing nozzle based on valve body rotation, which can rotate the nozzle by 180 degrees, backflush the nozzle by using the original nozzle water pipe, and prevent the nozzle from being blocked.

[0005] The equipment comprises a ball valve, the ball valve comprises a valve core and a valve sleeve;

[0006] The valve sleeve comprises a water inlet and a water outlet;

[0007] A nozzle is fixedly arranged in the valve core, and the nozzle is horizontally arranged in the water channel of the valve core.

[0008] The valve core of the ball valve can be horizontally rotated by 360 degrees in the valve sleeve.

[0009] Further, when the water inlet end of the nozzle faces the water inlet side of the valve sleeve, water is sprayed outward through the nozzle nozzle and the valve sleeve water outlet; when the valve core is rotated by 90 degrees based on the water passing state, the nozzle is closed and stopped; when the valve is rotated by 180 degrees based on the water passing state, the nozzle can be backflushed, and water enters the nozzle nozzle and backflushes the internal nozzle, so that the nozzle is backflushed.

[0010] The utility model has the advantages that the utility model solves the problem of inconvenient cleaning of the nozzle in the prior art, can backflush the nozzle at any time by rotating the valve core, is convenient to operate, greatly improves the nozzle cleaning efficiency, has simple equipment structure, and can correspondingly improve the service life of the nozzle equipment.

[0016] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0017] Reference Figure 1 , Figure 2 Figure 3 The present invention provides a backflushable nozzle, which includes a ball valve 4, wherein the ball valve 4 includes a valve core and a valve sleeve.

[0018] The valve sleeve includes an inlet 1 and an outlet 3;

[0019] A nozzle 2 is fixedly installed inside the valve core, and the nozzle 2 is horizontally installed in the water channel of the valve core.

[0020] The valve core of the ball valve 4 can rotate 360 ​​degrees horizontally within the valve sleeve.

[0021] Furthermore, when the water inlet of the nozzle 2 faces the water inlet 1 of the valve sleeve, water flows through the nozzle of the nozzle 2 and the water outlet 3 of the valve sleeve and sprays outward; when the water is flowing, rotating the valve core ninety degrees will shut off the nozzle 2; when the water is flowing, rotating the valve one hundred and eighty degrees will backflush the nozzle 2, and water will flow through the nozzle of the nozzle 2 and backflush the inside of the nozzle 2, thus achieving backwashing of the nozzle 2.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0023] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
