Description

Technical Field

[0001] This utility model relates to the field of stainless steel pump and valve casting technology, and in particular to a high-strength wear-resistant stainless steel pump and valve casting. Background Technology

[0002] Pump valves are a general term for pumps and valves. They are industrial equipment used for liquid transportation. Pump valves are usually manufactured by casting. In the existing stainless steel pump valve castings, the valve body and the flange on top are cast together. The connection between the two is relatively weak. The flange on top of the valve body is usually rigidly connected to other parts by bolts. This causes the connection between the flange and the valve body to be subjected to greater stress, which is prone to stress concentration and thus damage to the connection.

[0003] For example, in the prior art, the patent with authorization announcement number CN118208578B discloses a high-strength wear-resistant stainless steel pump valve casting and its preparation method. The device adds a connecting block and a reinforcing ring at the connection between the connecting flange and the valve body, which effectively increases the connection strength between the two, avoids the situation of stress concentration causing damage and detachment, and extends the service life of the stainless steel pump valve casting.

[0004] However, the valve body of the pump valve and the pipe body of the connecting flange are connected in an irregular shape. During the transportation of the valve body, the stability of the valve body partly depends on the stability of the pipe body connected to the connecting flange, which makes the valve body and the pipe body connected to the connecting flange prone to damage. Therefore, a high-strength wear-resistant stainless steel pump valve casting is designed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology and to propose a high-strength wear-resistant stainless steel pump valve casting.

[0006] The technical problem to be solved by this utility model is to provide a high-strength wear-resistant stainless steel pump valve casting, which solves the problem that the connection between the valve body and the pipe body of the connecting flange is prone to breakage in the prior art.

[0007] This utility model provides a high-strength wear-resistant stainless steel pump valve casting, including a valve body, reinforcing ribs, a flange mounting pipe, a connecting flange, reinforcing components, and reinforcing blocks. Multiple reinforcing ribs are evenly spaced on the outer surface of the valve body. A flange mounting pipe is installed through the valve body. A connecting flange is fixedly installed on the top of the flange mounting pipe. A reinforcing component is installed at the connection between the connecting flange and the flange mounting pipe. A reinforcing block is fixedly installed at the connection between the flange mounting pipe and the valve body.

[0008] Preferably, the angle between the flange mounting pipe and the valve body is 45°-60°, and the reinforcing block is triangular.

[0009] Preferably, the bottom of the reinforcing block is fixedly disposed on the valve body, and the side of the reinforcing block is fixedly disposed on the side of the flange mounting pipe.

[0010] Preferably, the reinforcing rib is semi-cylindrical and extends to the outer surface of the flange mounting pipe.

[0011] Preferably, the reinforcing component includes a reinforcing triangular plate, a widening vertical plate, and a widening horizontal plate. The widening vertical plate is fixedly disposed on the side of the reinforcing triangular plate, and the widening horizontal plate is fixedly disposed on the upper surface of the reinforcing triangular plate.

[0012] Preferably, the widening vertical plate is fixedly disposed on the side of the flange mounting pipe, the widening horizontal plate is fixedly disposed on the bottom surface of the connecting flange, and the connection between the widening vertical plate and the flange mounting pipe is an arc shape that matches the flange mounting pipe.

[0013] Preferably, the outer surface of the valve body and the flange mounting pipe is provided with a frosted layer.

[0014] Compared with the prior art, this utility model has at least the following beneficial effects:

[0015] 1. This utility model incorporates a reinforcing block, which strengthens the connection between the flange mounting pipe and the valve body, ensuring the strength of the connection and preventing damage.

[0016] 2. This utility model features reinforcing ribs that strengthen the valve body and flange mounting pipe, further ensuring the strength of the valve body. When the valve body rubs against other objects, the reinforcing ribs are the first to contact the other objects, increasing wear resistance.

[0017] By incorporating reinforcing components, the reinforcing triangular plate strengthens the connection between the flange mounting pipe and the connecting flange. Furthermore, the widened vertical and horizontal plates increase the contact area between the reinforcing components and the flange mounting pipe and connecting flange, thereby enhancing stability, preventing the connecting flange from detaching from the flange mounting pipe, and ensuring service life.

[0018] 3. This utility model has a frosted layer, which increases the friction on the outer surface of the valve body, making it easier to handle. Attached Figure Description

[0026] Example: Figures 1-4 As shown, an embodiment of this utility model provides a high-strength wear-resistant stainless steel pump valve casting, including a valve body 1, reinforcing ribs 2, a flange mounting pipe 3, a connecting flange 4, reinforcing components, and reinforcing blocks 6. Multiple reinforcing ribs 2 are evenly spaced on the outer surface of the valve body 1. A flange mounting pipe 3 is inserted through the valve body 1. A connecting flange 4 is fixedly installed on the top of the flange mounting pipe 3. A reinforcing component is installed at the connection between the connecting flange 4 and the flange mounting pipe 3. A reinforcing block 6 is fixedly installed at the connection between the flange mounting pipe 3 and the valve body 1.

[0027] In this embodiment, the angle between the flange mounting pipe 3 and the valve body 1 is 45°-60°, and the reinforcing block 6 is triangular to ensure the stability of the reinforcing block 6 and the reinforcement effect.

[0028] In this embodiment, the bottom of the reinforcing block 6 is fixedly disposed on the valve body 1, and the side of the reinforcing block 6 is fixedly disposed on the side of the flange mounting pipe 3. The reinforcing block 6 can increase the contact area when the valve body 1 is connected to the flange mounting pipe 3, thereby increasing stability.

[0029] By providing a reinforcing block 6, the connection between the flange mounting pipe 3 and the valve body 1 can be strengthened, ensuring the strength of the connection between the valve body 1 and the flange mounting pipe 3 and preventing damage to the connection between the valve body 1 and the flange mounting pipe 3.

[0030] In this embodiment, the reinforcing rib 2 is semi-cylindrical and extends to the outer surface of the flange mounting pipe 3.

[0031] By providing reinforcing ribs 2, the valve body 1 and flange mounting pipe 3 can be strengthened, further ensuring the strength of the valve body 1. When the valve body 1 rubs against other objects, the reinforcing ribs 2 will contact other objects first, increasing wear resistance.

[0032] In this embodiment, the reinforcing component includes a reinforcing triangular plate 5, a widening vertical plate 501, and a widening horizontal plate 502. The widening vertical plate 501 is fixedly disposed on the side of the reinforcing triangular plate 5, and the widening horizontal plate 502 is fixedly disposed on the upper surface of the reinforcing triangular plate 5.

[0033] In this embodiment, the widening vertical plate 501 is fixedly disposed on the side of the flange mounting pipe 3, and the widening horizontal plate 502 is fixedly disposed on the bottom surface of the connecting flange 4. The connection between the widening vertical plate 501 and the flange mounting pipe 3 is an arc shape that matches the flange mounting pipe 3, so as to ensure the contact area between the widening vertical plate 501 and the flange mounting pipe 3.

[0034] By incorporating reinforcing components, the reinforcing triangular plate 5 can strengthen the connection between the flange mounting pipe 3 and the connecting flange 4. Furthermore, by widening the vertical plate 501 and the horizontal plate 502, the contact area between the reinforcing components and the flange mounting pipe 3 and the connecting flange 4 can be increased, thereby enhancing stability and preventing the connecting flange 4 from detaching from the flange mounting pipe 3, thus ensuring service life.

[0035] In this embodiment, a frosted layer 101 is provided on the outer surface of the valve body 1 and the flange mounting pipe 3.

[0036] The frosted layer 101 increases the friction on the outer surface of the valve body 1, making it easier to handle.

[0037] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
