Description

Technical Field

[0001] This utility model relates to a nozzle, and more particularly to a nozzle that is adaptive to pipeline pressure, which adjusts the opening of the nozzle to regulate and stabilize the pipeline pressure, specifically a nozzle with a pressure-stabilizing structure. Background Technology

[0002] Traditional nozzles only have a simple spraying function. Spraying systems employ pressure stabilizing components to ensure pressure meets operating requirements without damaging the entire system. Without a pressure stabilizing control element, these nozzles cannot achieve pressure stabilization. Therefore, there is a need for a nozzle with an adaptively adjustable pressure stabilizing structure to ensure relative pressure stability in the spraying system and protect it. Utility Model Content

[0003] The purpose of this invention is to address the pressure stabilization problem of existing nozzles in systems without pressure stabilization control components. It designs a method that adjusts the nozzle opening amount by changing the system pressure to achieve pressure stabilization of the system and protect the system pressure stability.

[0004] The technical solution of this utility model is:

[0005] A pressure-stabilizing nozzle includes a housing and a pressure-stabilizing nozzle head. The pressure-stabilizing nozzle head includes a spray cap, a suspension, a valve core, and an adjusting rod, all coaxially mounted. The spray cap is a hollow cylindrical shape, with its sidewalls sealed and fixed within the housing. A spray hole is opened at the top of the spray cap, and the suspension is fixed to the rear end of the top of the spray cap. A spray hole is opened at the top of the suspension, and an opening at the bottom of the suspension allows the bottom of the valve core to be inserted. The valve core includes a cylindrical bottom and a bullet-shaped head, the diameter of which is larger than the diameter of the cylindrical bottom, forming a stepped surface. A compression spring is fitted into the cylindrical bottom of the valve core and abuts against the bottom of the suspension and the stepped surface of the valve core. The adjusting rod is a hollow cylinder, its outer wall threaded to the bottom of the spray cap. Under the action of the compression spring, the bullet-shaped head of the valve core contacts the inner wall of the adjusting rod.

[0006] Preferably, the bullet-shaped head of the valve core is provided with a transverse groove, and a sealing ring is embedded in the groove, so that the sealing ring contacts and seals the inner wall of the adjusting rod.

[0007] Preferably, there are multiple pressure-stabilizing nozzles, which are evenly distributed and installed on the outer casing.

[0008] Preferably, the nozzle is further provided with a spray head.

[0009] Preferably, the nozzles are configured as multiple nozzles, evenly distributed and installed on the housing.

[0010] Beneficial effects of this utility model

[0011] 1. This solves the long-standing problem that sprinkler systems can only rely on pressure-stabilizing control elements to stabilize the pipeline system. Using this type of pressure-stabilizing nozzle helps to further improve the safety and pressure stabilization capability of the sprinkler system.

[0012] 2. The structure is simple and easy to manufacture, and can be realized using existing technologies, without affecting the existing sprinkler system. Attached Figure Description

[0015] Figure 3 This is a schematic diagram of each side of the present invention. Detailed Implementation

[0016] The present invention will be further described below with reference to embodiments, but the scope of protection of the present invention is not limited thereto:

[0017] A nozzle with a pressure-stabilizing structure, combined with Figure 1 and Figure 3 It includes a housing 1, a nozzle 2 (there can be zero or several nozzles 2, and there can be one or several pressure-stabilizing nozzles 3), and a pressure-stabilizing nozzle 3. The nozzles 2 and pressure-stabilizing nozzles 3 are evenly distributed and installed on the housing 1. Its innovation is that the pressure-stabilizing nozzles 3 are installed on the housing 1.

[0018] Combination Figure 2 The pressure-stabilizing nozzle 3 includes a spray cap 301 mounted on the housing 1, a suspension 302 mounted on the top of the spray cap 301, a valve core 306 with a compression spring 303 mounted on one end and a sealing ring 305 mounted on the other end, the valve core 306 and the suspension 302 being coaxially mounted, the valve core 306 and the adjusting rod 304 being coaxially mounted, the sealing ring 305 being mounted on the valve core 306 and making sealing contact with the adjusting rod 304, the adjusting rod 304 and the spray cap 301 being coaxially mounted and connected by threads.

[0019] Parts not covered in this utility model, such as pipelines and electrical control, are the same as those in the prior art.

[0020] The working process of this utility model is as follows: Figure 3 As shown. Install nozzle 2 and pressure-stabilizing nozzle 3 on the housing as needed, and connect housing 1 to the main pipeline using thread 101.

[0021] When liquid flows into the nozzle, if there is a nozzle 2, the nozzle 2 will spray. When the pipeline pressure continues to increase, the pressure stabilizing nozzle 3 will open and spray. When the pipeline pressure drops, the pressure stabilizing nozzle 3 will close and stop spraying.

[0022] The specific structural principle of the pressure-stabilizing nozzle 3 is as follows: When liquid flows into the nozzle housing 1, when the axial pressure of the liquid applied to the valve core 306 is greater than the axial thrust of the compression spring 303, the valve core 306 moves inward along the axial direction. The inward movement of the valve core 306 drives the sealing ring 305 away from the adjusting rod 304. At this time, the pressure-stabilizing nozzle 3 opens and sprays liquid outward. Conversely, when the axial thrust of the compression spring 303 is greater than the axial pressure of the liquid applied to the valve core 306, the compression spring 303 pushes the valve core 306 to press the sealing ring 305 tightly against the adjusting rod 304. At this time, the pressure-stabilizing nozzle 3 is in a sealed state and stabilizes the pressure. The adjusting rod 304 can adjust the compression amount of the compression spring 303, thereby adjusting the thrust of the compression spring 303.

[0023] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
