Description

Technical Field

[0001] This utility model relates to a pressure-opening nozzle, which is applicable to petrochemical, food, and industrial fields. Background Technology

[0002] In the petrochemical industry, during air-cooled cooling projects, the high ambient temperature in summer often results in insufficient cooling load for dry air-cooled systems, causing the outlet material temperature to exceed the design temperature. This has led to the development of auxiliary cooling systems such as dry air-cooled spray systems. Refineries use various types of nozzles to spray water onto the dry air-cooled systems. The air-cooled systems then evaporate the water to achieve heat dissipation.

[0003] Currently, refineries use water spraying to lower the temperature of dry air coolers. However, this method has several problems. The water spray volume is difficult to control. Due to continuous water spraying, when the spray volume is too high, the dry air cooler cannot evaporate so much water, causing water to fall below the air cooler. The accumulated water will accelerate the corrosion of the metal platform. If the accumulated water drips into the power source, it may lead to more serious consequences. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this utility model discloses a pressure-opening nozzle. The nozzle includes a nozzle, a universal ball head, a universal ball head housing, a check valve housing, a sealing cone, a spring, and a support base. The nozzle is characterized in that: the nozzle is connected to the universal ball head via an external thread at the nozzle inlet end; the universal ball head housing is connected to the check valve housing via an internal thread at one end; the universal ball head is clamped between the check valve housing and the universal ball head housing; and the sealing cone, spring, and support base are sequentially installed inside the check valve housing from left to right.

[0005] The check valve housing integrates a check valve consisting of a sealing cone, a spring, and a support base.

[0006] The outer circle of the support base has an external thread that mates with the internal thread of the check valve housing, and the position of the support base is adjusted by using a threaded connection.

[0007] Advantages of the device described in this utility model:

[0008] 1. Compared with traditional nozzles, this nozzle can achieve intermittent spraying, which is more environmentally friendly, saves water resources, and can make full use of water resources.

[0009] 2. This nozzle can achieve precise control, controlling whether the nozzle opens according to the set opening pressure, which is unprecedented compared to traditional nozzles.

[0010] 3. This nozzle has a strong environmental adaptability. In addition to the pressure-activated function, it also has an adjustable angle nozzle, making it more widely applicable. If the spray position needs to be changed during use, it can be adjusted directly.

[0011] 4. This nozzle can be used with an automatic control system to achieve automatic operation, greatly saving manpower and material resources.

[0012] The device described in this utility model is applicable not only to newly built devices, but also to the renovation of existing devices. Attached Figure Description

[0015] The scope of protection of this utility model patent is not limited to the following embodiments. All improved technologies made based on the technical principles of this utility model are within the scope of protection of this patent.

[0016] To further illustrate the spirit of this patent, the following embodiments will be described in further detail:

[0017] like Figure 1 The diagram shown is a typical structural diagram of the device, including a nozzle (7), a universal ball head (6), a universal ball head housing (5), a check valve housing (1), a sealing cone (2), a spring (3), and a support base (4). The nozzle (7) is connected to the universal ball head (6) via the external thread at the nozzle inlet end. The universal ball head housing (5) is connected to the external thread at the outlet end of the check valve housing (1) via one end of its internal thread. The universal ball head (6) is clamped by the check valve housing (1) and the universal ball head housing (5). The sealing cone (2), spring (3), and support base (4) are installed in the check valve housing (1) in order from left to right, as shown in the attached diagram. Figure 1 As shown.

[0018] When the incoming water pressure reaches the pressure setting value, the sealing cone is popped open, and the incoming water passes through the check valve composed of the sealing cone (2), spring (3), and support base (4). Then the incoming water enters the inlet end of the nozzle (7), and after being guided by the internal guide of the nozzle, the incoming water is sprayed out through the nozzle spray hole to complete the entire process. In addition, the universal ball head (6) can adjust the spray direction of the nozzle. When the incoming water pressure is lower than the pressure setting value, the sealing cone will not open and the nozzle will not work.

[0019] In practice, the incoming liquid pressure can be controlled via DCS or PLC to achieve intermittent spraying from the nozzles, preventing excessive water flow and water accumulation under the air cooler. This also saves manpower and resources. Using a reasonable control program, by controlling the incoming water pressure and adjusting the spray interval and duration based on the temperature of the dry-type air cooler, automatic control can be achieved. This solves the problem of insufficient cooling load on the air cooler in summer.
