Description

Technical Field

[0001] This utility model belongs to the field of flange technology and relates to water pump sealing flanges. Background Technology

[0002] Water pumps are widely used tools. Currently, for stationary water pumps, flanges are generally used for connection and installation when connecting pipelines.

[0003] Traditional flanges do not provide a tight enough seal at pipe connections, relying solely on the sealing ring. Over time, the aging of the sealing ring can easily lead to water leakage at the flange connection, affecting the sealing performance of the flange connection. To address this issue, we designed a water pump sealing flange to solve the above-mentioned technical problems. Summary of the Invention

[0004] The purpose of this invention is to provide a water pump sealing flange to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solution: a water pump sealing flange, including a first flange and a second flange, wherein the first flange is fixedly connected to the water pump outlet end, and the second flange is fixedly connected to the end of a water pipe. Multiple threaded holes are equidistantly spaced along the circumference of the surfaces of the first and second flanges, and fixing bolts are inserted into the interior of each of the multiple threaded holes. A hexagonal nut is threaded to one end of each fixing bolt. Multiple concave grooves are equidistantly spaced in the middle of the sides of the first and second flanges, and a convex strip is provided between adjacent concave grooves. The convex strip on the surface of the first flange presses against the concave groove on the surface of the second flange, and the convex strip on the surface of the second flange presses against the concave groove on the surface of the first flange. A sealing collar is fitted at the connection between the first and second flanges. The purpose of this design is to achieve a tight seal at the connection between the first and second flanges through the cooperation of multiple concave grooves and multiple convex strips on the pump flange. Furthermore, the sealing ring fitted at the connection between the first and second flanges further seals the gap between them, effectively improving the sealing performance at the connection between the pump and the water pipe.

[0006] In the aforementioned water pump sealing flange, the first flange has T-shaped grooves at both its top and bottom. T-shaped sliders are slidably connected inside each of the two T-shaped grooves, and these sliders are fixedly connected to the sides of the inner wall of the sealing ring. This arrangement is intended to move the sealing ring to the connection point between the first and second flanges via the T-shaped sliders.

[0007] In the aforementioned water pump sealing flange, the inner wall of the sealing collar has an annular mounting groove, and an annular sealing strip is nested and fixed within the inner wall of the annular mounting groove. The inner wall of the annular sealing strip abuts against the connection between the first flange and the second flange. This arrangement aims to further seal the connection gap between the first flange and the second flange using the annular sealing strip.

[0008] In the aforementioned water pump sealing flange, the outer wall of the sealing collar is threaded with multiple locking bolts at equal intervals along the circumference, and the surface of the second flange is provided with multiple locking screw holes at equal intervals along the circumference, and the multiple locking bolts are threadedly connected to the corresponding locking screw holes.

[0009] In the aforementioned water pump sealing flange, each of the locking bolts has a cross-shaped slot at its tip, and a gasket is fitted at the connection between the locking bolt and the locking screw hole. This arrangement facilitates the fixing of the sealing ring by locking the bolts with the locking screw hole.

[0010] In the aforementioned pump sealing flange, the inner diameter of the sealing ring is adapted to the outer diameter of the first flange and the second flange. This arrangement aims to reduce the gap between the sealing ring and the first and second flanges.

[0011] Compared with the prior art, the advantages of the water pump sealing flange of this utility model are as follows: the water pump flange achieves the sealing performance at the connection between the first flange and the second flange through the cooperation of multiple concave pressure grooves and multiple convex pressure strips, and further seals the connection gap between the first flange and the second flange through the sealing sleeve fitted at the connection between the first flange and the second flange, effectively improving the sealing performance at the connection between the water pump and the water pipe.

Detailed Implementation

[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] like Figure 1-4 As shown, the water pump sealing flange of this utility model includes a first flange 1 and a second flange 2. The first flange 1 is fixedly connected to the water outlet end of the water pump, and the second flange 2 is fixedly connected to the end of the water pipe. Multiple threaded holes 5 are equidistantly opened on the surface of the first flange 1 and the second flange 2 along the circumference. Fixing bolts are inserted into the multiple threaded holes 5, and a hexagonal nut is threaded to one end of each fixing bolt. Multiple concave pressure grooves 3 are equidistantly opened in the middle of the side of the first flange 1 and the second flange 2. A convex pressure strip 4 is provided between two adjacent concave pressure grooves 3. The convex pressure strip 4 on the surface of the first flange 1 is pressed against the concave pressure grooves 3 on the surface of the second flange 2, and the convex pressure strip 4 on the surface of the second flange 2 is pressed against the concave pressure grooves 3 on the surface of the first flange 1. A sealing collar 6 is sleeved and connected at the connection between the first flange 1 and the second flange 2.

[0019] Specifically, the pump flange achieves a tight seal at the connection between the first flange 1 and the second flange 2 through the cooperation of multiple concave grooves 3 and multiple convex strips 4. The sealing ring 6 fitted at the connection between the first flange 1 and the second flange 2 further seals the connection gap between the first flange 1 and the second flange 2, effectively improving the sealing performance at the connection between the pump and the water pipe.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the water pump sealing flange of this utility model has T-shaped grooves 7 at both the top and bottom of the first flange 1. T-shaped sliders 12 are slidably connected inside the two T-shaped grooves 7. The two T-shaped sliders 12 are fixedly connected to the side of the inner wall of the sealing ring 6.

[0021] Specifically, the T-shaped slider 12 slides inside the T-shaped groove 7, thereby driving the movement of the sealing collar 6.

[0022] The inner wall of the sealing ring 6 is provided with an annular mounting groove 10, and an annular sealing strip 11 is nested and fixed on the inner wall of the annular mounting groove 10. The inner wall of the annular sealing strip 11 abuts against the connection between the first flange 1 and the second flange 2.

[0023] Specifically, by having the annular sealing strip 11 abut against the gap between the first flange 1 and the second flange 2, the sealing performance at the connection between the first flange 1 and the second flange 2 is further improved.

[0024] The outer wall of the sealing ring 6 is threaded with multiple locking bolts 8 at equal intervals along the circumference. The surface of the second flange 2 is provided with multiple locking screw holes 9 at equal intervals along the circumference. The multiple locking bolts 8 are threadedly connected to the corresponding locking screw holes 9.

[0025] Specifically, the sealing ring 6 is secured by threaded connection between the locking bolt 8 and the corresponding locking screw hole 9.

[0026] The top of each of the multiple locking bolts 8 is provided with a cross-shaped slot, and a washer is provided at the connection between the locking bolt 8 and the locking screw hole 9.

[0027] Specifically, the cross-shaped slot makes it easy to tighten the bolt 8 by rotating it with a cross-shaped screwdriver.

[0028] The inner diameter of the sealing ring 6 is adapted to the outer diameter of the first flange 1 and the second flange 2.

[0029] Specifically, by matching the inner diameter of the sealing ring 6 with the outer diameter of the first flange 1 and the second flange 2, the gap at the connection between the sealing ring 6 and the first flange 1 and the second flange 2 is reduced.

[0030] In specific implementation, when using this flange for connecting the water pump and the water pipe, firstly, fix the first flange 1 at the outlet of the water pump and fix the second flange 2 at the end of the water pipe. Then, fit the first flange 1 and the second flange 2 together. When the first flange 1 and the second flange 2 are fitted together, the convex pressure strip 4 and the concave pressure groove 3 are pressed together. Then, thread the fixing bolts to the threaded holes 5 and thread the hexagonal nuts to the fixing bolts to complete the connection between the first flange 1 and the second flange 2. Then, manually push the sealing ring 6 towards the second flange 2 so that the locking bolts 8 on the surface of the sealing ring 6 are aligned with the locking screw holes 9 on the surface of the second flange 2. Then, thread the locking bolts 8 and the locking screw holes 9 to further seal the connection gap between the first flange 1 and the second flange 2, thereby improving the sealing effect of the connection between the water pump and the water pipe.
