Flow adjustable nozzle

Abstract

This utility model relates to the field of chemical technology and discloses an adjustable flow nozzle, including a nozzle seat with an internal threaded interface in its inner cavity. A distribution cone is installed inside the nozzle seat, and a fixing nut is threaded to the surface of the nozzle seat. The conical surface of the distribution cone and the nozzle seat form an adjustable flow channel gap. This utility model, through the coordinated use of the fixing nut, nozzle seat, and distribution cone, allows adjustment of the spray liquid flow rate by rotating the distribution cone to change the flow channel gap between it and the nozzle seat. After adjustment, the fixing nut locks the position of the distribution cone, ensuring a stable gap. This solves the problem of traditional nozzles where the position of the cone and nozzle is relatively fixed after flow calculation, which cannot guarantee optimal spraying effect in actual use, and requires replacement with nozzles of different specifications whenever operating conditions change.

Description

Technical Field

[0001] This utility model belongs to the field of chemical technology, and in particular relates to a flow-adjustable nozzle. Background Technology

[0002] Chemical engineering is an industrial field that applies the principles of basic sciences such as chemistry, physics, and biology to transform raw materials into products with specific functions through engineering techniques. It covers industries such as energy, medicine, materials, and environmental protection, and involves links such as material synthesis, process design, equipment optimization, and safety control. It is one of the core pillars driving the development of modern industrial systems and technological innovation.

[0003] The temperature of the spray liquid in the chemical system is generally above 150℃, and the flow rate varies depending on the real-time production capacity of the unit. The problem with the above technology is that the position of the cone and nozzle is relatively fixed after the flow rate is calculated. In actual use, it is impossible to guarantee the best spraying effect. Moreover, as long as the operating conditions change, it is necessary to replace the nozzle with a different specification. Utility Model Content

[0004] In view of the problems existing in the prior art, the present invention provides a flow-adjustable nozzle that can overcome or at least partially solve the above problems.

[0005] This invention is implemented as follows: a flow-adjustable nozzle includes a nozzle seat, a distribution cone, and a fixing nut. The nozzle seat has an internal threaded interface in its inner cavity. The distribution cone is installed inside the nozzle seat. The fixing nut is threaded to the surface of the nozzle seat. The cone surface of the distribution cone and the nozzle seat form an adjustable flow channel gap.

[0006] To control the flow rate, preferably, the flow rate of the nozzle seat is 1-5 m / s. 3 / h.

[0007] For ease of connection, preferably, the nozzle seat adopts a standard threaded interface G1 / 2.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] This invention utilizes a combination of a fixing nut, a nozzle seat, and a distribution cone. By rotating the distribution cone, the flow channel gap between it and the nozzle seat is changed, thereby adjusting the spray liquid flow rate. After adjustment, the fixing nut locks the distribution cone in place, ensuring a stable gap. This solves the problem of traditional nozzles where the position of the cone and nozzle is relatively fixed after flow calculation, making it impossible to guarantee optimal spraying effect in actual use. Furthermore, it eliminates the need to replace nozzles with different specifications whenever operating conditions change. Attached Figure Description

[0013] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0014] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0015] like Figures 1 to 2 As shown, the present invention provides an adjustable flow nozzle, including a nozzle seat 2, an internal threaded interface in the inner cavity of the nozzle seat 2, a distribution cone 3 installed inside the nozzle seat 2, a fixing nut 1 threadedly connected to the surface of the nozzle seat 2, and the cone surface of the distribution cone 3 and the nozzle seat 2 forming an adjustable flow channel gap.

[0016] The flow rate of nozzle seat 2 is 1-5 m / s. 3 / h.

[0017] Nozzle seat 2: It is equipped with an internal threaded interface for connecting to the liquid inlet pipe in order to control the flow rate.

[0018] Distribution cone 3: Located inside nozzle seat 2, it forms an adjustable flow channel gap with nozzle seat 2 through the cone surface.

[0019] Fixing nut 1: Sleeve onto the outer wall of nozzle seat 2, and lock the relative position of distribution cone 3 and nozzle seat 2 through threaded engagement.

[0020] For easy connection, nozzle seat 2 adopts standard threaded interface G1 / 2 or NPT1 / 2, which is convenient to connect to the pipeline and has high maintenance efficiency.

[0021] Reduce replacement costs: One sprayer can be used for multiple purposes, eliminating the need to purchase multiple nozzles of different specifications for different flow conditions, thus reducing spare parts inventory and replacement frequency;

[0022] Extended service life: Made of high-temperature resistant materials (such as stainless steel or alloys), it can adapt to long-term high-temperature environments and reduce the need for replacement due to corrosion or deformation.

[0023] Vibration-resistant design: The fixing nut 1 adopts a double-thread locking structure to prevent gap displacement caused by pipeline vibration;

[0024] High temperature adaptability: After the flow channel gap is adjusted, thermal expansion is compensated by the preload of fixing nut 1 to ensure the gap stability under high temperature conditions;

[0025] Flexible adjustment: Supports 1-5m 3 The flow rate can be continuously adjusted within a range of / h to adapt to the capacity requirements of different chemical plants.

[0026] Quick assembly and disassembly: Nozzle seat 2 adopts a standard threaded interface (such as G1 / 2 or NPT1 / 2), which makes it easy to connect to the pipeline and provides high maintenance efficiency;

[0027] Visualized debugging: The spray pattern can be observed by adjusting the distribution cone 3 at room temperature. After determining the optimal parameters, they can be directly applied to high-temperature conditions, simplifying the debugging process.

[0028] The working principle of this utility model:

[0029] During use, the flow channel gap between the distribution cone 3 and the nozzle seat 2 is changed by rotating the distribution cone 3, thereby adjusting the spray liquid flow rate. After adjustment, the position of the distribution cone 3 is locked using the fixing nut 1 to ensure the gap is stable.
