Description

Technical Field

[0001] The utility model relates to the technical field of large-displacement float traps, in particular to a large-displacement float trap. Background Art

[0002] In modern industrial production, steam is widely used as an important energy medium in various fields, such as chemical industry, textile, food processing, electricity, etc. During the use of steam, a large amount of condensate will inevitably be produced. In order to effectively discharge this condensate and prevent steam leakage, steam traps came into being.

[0003] After searching, the applicant discovered a Chinese patent for "a large-displacement float-type steam trap" with the publication (announcement) number "CN219712621U." This patent primarily achieves a quick connection by connecting the outlet and inlet pipes to a first flange, adjusting the position of a rubber block by turning a screw, sliding the flange onto a fixed pipe, inserting a guide post onto the fixed pipe, and clamping the guide post with a rubber block. However, this patent fails to effectively filter impurities in the water flow. During actual use, impurities may gradually accumulate inside the steam trap, blocking the valve port and affecting the normal operation of the equipment. Therefore, we propose a large-displacement float-type steam trap. Utility Model Content

[0004] The purpose of the present utility model is to provide a large-displacement float steam trap to solve the problem proposed in the above-mentioned background technology that impurities in the water flow cannot be effectively filtered. During actual use, impurities may gradually accumulate inside the steam trap, resulting in blockage of the valve port, thereby affecting the normal operation of the equipment.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a large-displacement float steam trap, comprising a steam trap body and a connecting plate, a filter assembly being provided inside the steam trap body, the filter assembly comprising a filter screen, the top of the filter screen being fixedly connected to a support block, the support block being connected to a rotating wheel via a rotating rod, the rotating wheel being connected to a fixed block via a connecting plate and bolts, a threaded hole being provided on the top of the fixed block, and a plurality of groups of circumferentially distributed plugs being fixedly connected to the back of the connecting plate.

[0006] As a preferred solution, a float is fixedly mounted on the bottom of the steam trap body, and a bolt hole is opened on the surface of the steam trap body.

[0007] As a preferred solution, the inner walls of both sides of the support block are fixedly connected to the two ends of the rotating rod, the inner wall of the rotating wheel is rotatably connected to the outer wall of the rotating rod, and one side of the rotating wheel is fixedly connected to one end of the connecting plate.

[0008] As a preferred solution, the outer wall of the bolt is threadedly connected to the inner wall of the threaded hole, and the bottom of the fixing block is fixedly connected to the top of the steam trap body.

[0009] As a preferred solution, the bolt hole is connected through both sides of the filter screen, and the inner wall of the bolt hole is adapted to the outer wall of the plug.

[0010] As a preferred solution, a flow limiting component is provided inside the steam trap body, and the flow limiting component includes a torsion plate and a second nut. A first nut is provided on the upper surface of the torsion plate, and a torsion rod is threadedly connected to the inner wall of the first nut. The surface of the second nut is fixedly connected to the inner top wall of the steam trap body, and a flow limiting plate is fixedly installed on the outer wall of the torsion rod.

[0011] Technical effects and advantages of this utility model:

[0012] 1. Through the filter assembly, when the staff uses the steam trap body to drain water, the filter screen installed inside the steam trap body can effectively filter out solid particles, rust, scale and other impurities in the water flow, preventing these impurities from entering the steam trap body and causing valve port blockage, affecting the normal operation and drainage efficiency of the steam trap.

[0021] The surface of the filter screen 201 is also provided with a hole of the same size as the bolt hole 6. The bolt 209 can pass through the hole on the surface of the filter screen 201 and the bolt hole 6 on the surface of the steam trap body 1 to initially fix the filter screen 201 in a position between the connecting plate 5 and the steam trap body 1.

[0022] Specifically, through the provided filter assembly 2, when the operator uses the steam trap body 1 to perform drainage operations, the filter screen 201 configured inside the steam trap body 1 can effectively filter out solid particles, rust, scale and other impurities in the water flow, preventing these impurities from entering the steam trap body 1, thereby avoiding valve port blockage, ensuring the normal operation of the steam trap, and maintaining drainage efficiency. At the same time, through the connection relationship between the connecting plate 205 and the bolt 206, the filter screen 201 can be replaced or impurities on the filter screen 201 can be cleaned from time to time. Example 2

[0023] Please see the attached Figure 1 , Attachment Figure 2 And attached Figure 4 On the basis of Example 1, it is further obtained that a flow limiting component 3 is provided inside the steam trap body 1, and the flow limiting component 3 includes a torsion plate 301 and a second nut 303.

When the staff uses the drain valve body 1 to drain water, the filter screen 201 arranged inside the drain valve body 1 can effectively filter out solid particles, rust, scale and other impurities in the water flow. When the filter screen 201 needs to be replaced or the impurities on it need to be cleaned, the staff can twist the connecting plate 205 and rotate it to the upper end of the fixed block 207, and then fix or remove it through the bolt 206 and the threaded hole 208. Secondly, when the staff needs to meet specific drainage needs, they can manually twist the torsion rod 304, and the torsion rod 304 will drive the flow limiting plate 305 to rotate. At this time, the staff can adjust the angle of the flow limiting plate 305 according to needs, thereby realizing control of the drainage flow.
