Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water pump accessories, and particularly relates to a splash-proof packing gland. Background Art
[0002] Circulating water pumps are used to continuously circulate water or other fluids in a system, and are commonly found in cooling systems, heating systems, and air conditioning systems. Its main function is to keep the fluid flowing continuously to achieve uniform heat distribution or remove heat from the system. During the operation of the circulating water pump, a packing gland is often needed to seal the packing.
[0003] At present, when the circulating water pump is running, leakage water at the packing is used to keep the packing lubricated and cooled. However, due to the small flow-through area formed by the gap between the packing gland and the stuffing box body, the packing water splashes, causing the surrounding environment to be humid, affecting the working environment, and accelerating the corrosion of some parts. Content of the Utility Model
[0004] (1) Technical Problems to be Solved
[0005] The technical problem to be solved by the utility model is to provide a splash-proof packing gland that reduces the water flow speed by increasing the flow-through area of the packing leakage water, thereby preventing the packing leakage water from splashing, in view of the current situation of the prior art.

[0007] The utility model is realized through the following technical solutions: The utility model provides a splash-proof packing gland, which includes a left packing gland. A right packing gland is arranged on one side of the left packing gland. Connecting flanges are installed at both the upper and lower ends of the left packing gland and the right packing gland. A fastening bolt is installed between the two connecting flanges on the same side. Pressure relief holes are correspondingly formed on one side of the inner walls of the left packing gland and the right packing gland.
[0008] Furthermore, the aperture of the pressure relief hole is 12 mm, and the number of the pressure relief holes is 2 - 4.
[0009] By adopting the above technical solutions, the pressure relief holes can increase the water discharge area inside the packing gland, so as to reduce the pressure and speed of the packing leakage water when flowing out, and avoid the packing leakage water from splashing.
[0010] Furthermore, the positions of the pressure relief holes on the left packing gland and the right packing gland are both arc-shaped concave structures.
[0011] By adopting the above technical solutions, the reserved grooves can ensure the convenient docking and installation of the external pipeline connected to the water pump.
[0012] Furthermore, the left packing gland and the right packing gland have the same structure, and the connecting convex edge is correspondingly formed on the left packing gland and the right packing gland.
[0013] By adopting the above technical solution, the connecting convex edge can ensure the reliable butt joint installation of the left packing gland and the right packing gland.
[0014] Furthermore, the fastening bolt penetrates through two connecting convex edges on the same side, and the free end of the fastening bolt is provided with a fastening nut.
[0015] By adopting the above technical solution, it can be ensured that the fastening bolt can be reliably locked and fixed when passing through the corresponding connecting convex edge.
[0016] (III) Beneficial effects
[0017] Compared with the prior art, the present utility model has the following beneficial effects:
[0018] To solve the problem that there is leakage water at the packing during the operation of the current circulating water pump to keep the packing lubricated and cooled, but due to the small flow-through surface formed by the gap between the packing gland and the stuffing box body, the packing water splashes, causing the surrounding environment to be humid, affecting the working environment, and accelerating the corrosion of some parts. The present utility model respectively opens pressure relief holes on the left packing gland and the right packing gland, so that the packing gland can increase the flow-through area of the packing leakage water by means of the pressure relief holes during use, thereby reducing the water flow velocity, preventing the packing leakage water from splashing, and avoiding the humidity of the surrounding environment of the circulating water pump and the corrosion and damage of the parts around the circulating water pump.

[0019] Figure 1 is a schematic structural diagram of a splash-proof packing gland of the present utility model.
[0020] The description of the reference numerals is as follows:
[0021] 1. Left packing gland; 2. Right packing gland; 3. Fastening bolt; 4. Pressure relief hole; 5. Connecting convex edge. Specific embodiments
[0022] In order to make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0023] Such as Figure 1As shown in the figure, a splash-proof packing gland in this embodiment includes a left packing gland 1. A right packing gland 2 is arranged on one side of the left packing gland 1. Connecting flanges 5 are installed at both the upper and lower ends of the left packing gland 1 and the right packing gland 2. A fastening bolt 3 is installed between two connecting flanges 5 on the same side. On one side of the inner walls of the left packing gland 1 and the right packing gland 2, pressure relief holes 4 are correspondingly provided. The aperture of the pressure relief hole 4 is 12 mm, and the number of the pressure relief holes 4 is 2 - 4. The specific number of the pressure relief holes 4 needs to be determined according to the inner diameter of the packing gland. When the inner diameter of the packing gland is less than 100 mm, the number of the pressure relief holes 4 is 2. At this time, one pressure relief hole 4 is respectively provided on the left packing gland 1 and the right packing gland 2. When the inner diameter of the packing gland is greater than 100 mm, the number of the pressure relief holes 4 is 4. At this time, two pressure relief holes 4 are respectively provided on the left packing gland 1 and the right packing gland 2. The pressure relief holes 4 can increase the water drainage area inside the packing gland, so as to reduce the pressure and speed when the leaked water of the packing flows out, and avoid the splashing of the leaked water of the packing.
[0024] As Figure 1 As shown in the figure, in this embodiment, the positions of the left packing gland 1 and the right packing gland 2 where the pressure relief holes 4 are located are both arc-shaped concave structures. The reserved grooves can ensure the convenient butt joint installation of the external pipeline connected to the water pump. The left packing gland 1 and the right packing gland 2 have the same structure. The connecting flanges 5 are correspondingly formed on the left packing gland 1 and the right packing gland 2. The connecting flanges 5 can ensure the reliable butt joint installation of the left packing gland 1 and the right packing gland 2. The fastening bolt 3 passes through two connecting flanges 5 on the same side. The free end of the fastening bolt 3 is provided with a fastening nut, which can ensure that the fastening bolt 3 can be reliably locked and fixed when passing through the corresponding connecting flanges 5.
[0025] The specific implementation process of this embodiment is as follows: During use, first butt-join the left packing gland 1 and the right packing gland 2, and use the fastening bolt 3 to lock and fix the left packing gland 1 and the right packing gland 2. Then, just install the packing gland at the corresponding position on the circulating water pump, and the packing gland can be put into use. During the use process, by respectively providing the pressure relief holes 4 on the left packing gland 1 and the right packing gland 2, the packing gland can increase the flow-through area of the leaked water of the packing by means of the pressure relief holes 4 during use, thereby reducing the water flow speed, preventing the splashing of the leaked water of the packing, and avoiding the humidity of the environment around the circulating water pump and the corrosion and damage of the parts around the circulating water pump.
