A nozzle for spraying pipe cleaning agents

Abstract

This utility model discloses a nozzle for spraying pipeline cleaning agents, including a head and a tube. A filter screen is installed inside the head. The head and the tube are connected by an insertion joint and fixed together by bolts. The head has several spray holes, and the end of the tube away from the head has an interface. This relates to the field of nozzle technology. By inserting the head and the tube together and then using bolts to connect them, the head and the tube will not be difficult to separate due to rusted threads, thus facilitating the removal of the filter screen for cleaning or replacement. By setting a bridge pipe between the head and the tube, and installing corresponding valves on the head, the tube, and the bridge pipe, the nozzle can spray normally by controlling the opening of several valves. It can also spray the liquid back towards the filter screen, and the liquid washed off the filter screen will be discharged through the drain port at the bottom of the tube, thus cleaning the filter screen.

Description

Technical Field

[0001] This utility model relates to the field of nozzle technology, specifically a nozzle for spraying pipeline cleaning agents. Background Technology

[0002] A sprinkler head, or "nozzle" in English, is very similar in meaning to a spray nozzle, one being a common term and the other a more professional one. A sprinkler head is a crucial, even primary, component in many types of spraying, misting, oil spraying, and sandblasting equipment. Classified by structure, there are closed and open types. Based on the heat-sensitive element, there are glass bulb and fusible element sprinklers. According to installation method and spray pattern, there are upright, pendant, standard, sidewall, and ceiling-mounted types. Special types of nozzles include dry-type and automatically opening / closing sprinklers.

[0003] The existing nozzles have the following shortcomings:

[0004] The nozzle head and the tube are usually connected by threads. The threads are prone to rust, making disassembly difficult and making it inconvenient to clean the filter inside the nozzle. Utility Model Content

[0005] In view of the problems existing in a current nozzle for spraying pipe cleaning agents, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a nozzle for spraying pipeline cleaning agents, which solves the problem that the nozzle head and the pipe are usually connected by threads, which are prone to rust and make disassembly difficult, thus making it inconvenient to clean the filter screen inside the nozzle.

[0014] As a preferred embodiment of the nozzle for spraying pipeline cleaning agent described in this utility model, a sealing ring is provided in both the inlet and outlet.

[0015] Compared with existing technologies:

[0016] By inserting the head and the tube together and then using bolts to connect them, the head and the tube will not be difficult to separate due to rusted threads, making it easy to remove the filter for cleaning or replacement.

[0017] By installing a bridge pipe between the head and the pipe section, and installing corresponding valves on the head, pipe section and bridge pipe section, the nozzle can spray normally by controlling the opening of several valves. It can also make the liquid spray back towards the filter screen. The liquid washed off the filter screen is discharged through the drain port at the bottom of the pipe section, thus cleaning the filter screen. Attached Figure Description

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Example

[0024] This utility model provides a nozzle for spraying pipeline cleaning agents. Please refer to [link / reference]. Figure 1-2 The device includes a head 1 and a tube 2. The head 1 has several spray holes. The tube 2 has an interface 21 at one end away from the head 1. A filter screen 5 is installed inside the head 1. The head 1 and the tube 2 are connected by a plug-in joint and are fixed together by bolts. Since the head 1 and the tube 2 are connected by a plug-in joint rather than a threaded connection, it is easier to disassemble and assemble the head 1 and the tube 2, thus facilitating the replacement and cleaning of the filter screen 5 inside the head 1.

[0025] A first mating block 12 is welded to the outer wall of the head 1, and a second mating block 22 is welded to the outer wall of the tube 2. Internal threaded holes are provided at corresponding positions of the first mating block 12 and the second mating block 22. The first mating block 12 and the second mating block 22 are fixed together by bolts.

[0026] The head 1 has an integral support ring 3 in its inner cavity, and a first sealing ring 4 and a second sealing ring 6 are provided in the inner cavity of the head 1. The support ring 3, the first sealing ring 4, the filter screen 5 and the second sealing ring 6 are distributed in sequence.

[0027] In practical use:

[0028] Place the first sealing ring 4, the filter screen 5, and the second sealing ring 6 in the inner cavity of the head 1 in sequence, insert the end of the tube 2 into the head 1, and use bolts to fix the first mating block 12 and the second mating block 22 together. At this time, the first sealing ring 4 and the second sealing ring 6 are compressed to achieve a seal.

[0029] Remove the bolts securing the first docking block 12 and the second docking block 22, separate the tube 2 from the head 1, and remove the filter screen 5 for cleaning. Example

[0030] See attached document Figure 3-4Unlike Embodiment 1, a bridging pipe 7 is provided between the head 1 and the pipe 2. A first valve 12 is fixedly installed on the head 1, a second valve 11 is fixedly installed on the pipe 2, and a third valve 10 is fixedly installed on the bridging pipe 7. The pipe 2 has a drain port 13, and a sealing cap 14 is threadedly connected to the bottom of the drain port 13.

[0031] The head 1 has an inlet 8, the tube 2 has an outlet 9, the two ends of the bridge tube 7 are respectively inserted into the inlet 8 and the outlet 9, and a sealing ring is provided in both the inlet 8 and the outlet 9. The two ends of the bridge tube 7 are fixed to the inlet 8 and the outlet 9 by bolts.

[0032] The nozzle is not directly connected to the pump. Instead, it is connected to the pump via a flexible hose. The pump's vibration is not transmitted to the nozzle, so there is no issue of bolts loosening and causing the nozzle to separate from the hose under vibration or high pressure.

[0033] In practical use, the first sealing ring 4, the filter screen 5 and the second sealing ring 6 are placed in the inner cavity of the head 1 in sequence, the end of the tube 2 is inserted into the head 1, and the two ends of the bridge tube 7 are respectively inserted into the inlet 8 and the outlet 9. The two ends of the bridge tube 7 are fixed to the inlet 8 and the outlet 9 with bolts.

[0034] When using the nozzle normally, open the second valve 11 and the first valve 12, close the third valve 10, and connect the interface 21 to the liquid supply pipeline.

[0035] When cleaning the filter screen 5, close the second valve 11 and the first valve 12, open the third valve 10, remove the sealing cap 14, and the liquid enters the bridge pipe 7 through the pipe section 2. Then the liquid flows back towards the filter screen 5 and is discharged through the drain port 13, thus cleaning the filter screen 5.

[0036] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
