Description

Technical Field

[0001] This utility model relates to the field of valve casting technology, and more specifically to a combined valve casting. Background Technology

[0002] Valve castings refer to cast parts used in the manufacture of valves. These castings are typically made by pouring molten metal (such as iron, steel, copper or their alloys) into a mold of a specific shape, allowing it to cool and solidify to form the desired shape and size.

[0003] When manufacturing valve castings, in order to improve accuracy, two parts of the valve casting are usually cast as one piece. However, in order to simplify the casting process and facilitate casting, the two parts of the valve casting are made first and then assembled into one piece.

[0004] The two valve castings assembled in this way, as shown in the application number CN201420144034.3, "Rising Stem Gate Valve with Limit Indicator Position", are connected and combined into one piece by bolts. However, when assembling the "valve body and valve stem support", the bolt holes need to be aligned, which has the disadvantage of inconvenient assembly operation. Utility Model Content

[0005] The purpose of this utility model is to provide a combined valve casting in order to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] This utility model proposes a combined valve casting, including a valve body and a bracket, wherein the valve body is provided with a valve cavity and the bracket is provided with a through hole;

[0008] The valve body is provided with several sets of first connection holes, and the bracket is provided with several sets of second connection holes;

[0009] The valve body is provided with at least one set of slots, and the bracket is fixed with at least one set of blocks;

[0010] When the card block is inserted into the card slot and fits, the first connecting holes of several groups correspond one-to-one with the second connecting holes of several groups, and the through holes are centered and opposite to the valve cavity.

[0011] As a preferred embodiment of this utility model, a soft wear-resistant layer is attached and fixed inside the card slot and is attached to the card block.

[0012] As a preferred embodiment of this utility model, the first connecting hole connects to the card slot, and the second connecting hole penetrates both sides of the card block.

[0013] As a preferred embodiment of this utility model, a gasket groove is provided on one side of the first connecting hole and the second connecting hole.

[0014] As a preferred embodiment of this utility model, a washer is fitted inside the groove.

[0015] The beneficial effects of this utility model are as follows:

[0016] By shifting the bracket towards the valve body and inserting it into the slot via the locking block, positioning can be achieved. Multiple sets of first connecting holes can be directly aligned with multiple sets of second connecting holes, and the through hole can be centered and aligned with the valve cavity. This ensures fast alignment and facilitates subsequent assembly and fixation using bolts or other components passing through the first and second connecting holes. Furthermore, the first connecting holes, locking slots, and gaskets on the valve body, as well as the second connecting holes, locking blocks, and gaskets on the bracket, are all integrally cast, simplifying manufacturing.

[0022] like Figures 1-4 As shown, this utility model proposes: a combined valve casting, including a valve body 1 and a bracket 2. The valve body 1 is provided with a valve cavity 3, and the bracket 2 is provided with a through hole 4. The valve body 1 and the bracket 2 are pre-cast separately, and the bracket 2 is positioned above the valve body 1.

[0023] The valve body 1 is provided with several sets of first connecting holes 5. The first connecting holes 5 on the valve body 1 are arranged vertically and vertically, and multiple sets of first connecting holes 5 are provided. The multiple sets of first connecting holes 5 are integrally formed during the casting of the valve body 1, which facilitates manufacturing.

[0024] The bracket 2 is provided with several sets of second connection holes 6. The second connection holes 6 on the bracket 2 are arranged vertically and vertically, and multiple sets of second connection holes 6 are provided. The multiple sets of second connection holes 6 are integrally formed during the casting of valve body 1, which facilitates manufacturing.

[0025] The valve body 1 is provided with at least one set of slots 7. The slots 7 are set at the top of the valve body 1, and multiple sets of slots 7 are set. The multiple sets of slots 7 are integrally formed during the casting of the valve body 1, which facilitates manufacturing.

[0026] At least one set of locking blocks 8 are fixed on the bracket 2. The locking blocks 8 are set at the bottom of the bracket 2, and multiple sets of locking blocks 8 are set. The multiple sets of locking blocks 8 are integrally formed during the casting of the valve body 1, which facilitates manufacturing.

[0027] When the card block 8 is inserted into the card slot 7 and fits together, several sets of first connecting holes 5 are connected to several sets of second connecting holes 6 one by one, and the through hole 4 is centered and opposite to the valve cavity 3. Multiple sets of first connecting holes 5 are connected downwards to one set of second connecting holes 6 one by one. The through hole 4 is located directly above the center of the top of the valve cavity 3. The card slot 7 and the card block 8 are both tapered from top to bottom to facilitate the insertion of the card block 8 into the card slot 7.

[0028] By moving the bracket 2 toward the valve body 1 and inserting it into the slot 7 via the locking block 8, positioning can be achieved so that multiple sets of first connecting holes 5 are directly aligned with multiple sets of second connecting holes 6 and the through hole 4 is centered and aligned with the valve cavity 3. The alignment is fast and it is convenient to use bolts and other components to pass through the first connecting holes 5 and the second connecting holes 6 for subsequent assembly and fixation.

[0029] In addition: After the first connecting hole 5 and the second connecting hole 6 are integrally cast, they are reshaped using turning and grinding equipment to ensure good connectivity when the first connecting hole 5 and the second connecting hole 6 are connected; at the same time, after the slot 7 and the block 8 are integrally cast, they are also reshaped using turning and grinding equipment to improve the stability and accuracy when the slot 7 and the block 8 are fitted together.

[0030] The slot 7 has a soft wear-resistant layer attached to it and is attached to the card block 8. The soft wear-resistant layer can be a rubber layer, which provides good wear resistance. When the card block 8 is attached to the soft wear-resistant layer, it can provide flexible pressing, good stability, and can make slight adjustments to the relative communication space between the first connecting hole 5 and the second connecting hole 6.

[0031] The first connecting hole 5 connects to the slot 7, and the second connecting hole 6 passes through both sides of the block 8. The top of the first connecting hole 5 connects to the slot 7, and the second connecting hole 6 passes through the top and bottom sides of the block 8. When the valve body 1 and the bracket 2 are fixed by connecting the first connecting hole 5 and the second connecting hole 6 at this position, better clamping force can be provided to the slot 7 and the block 8.

[0032] like Figure 3 As shown, a gasket 9 is provided on one side of the first connecting hole 5 and the second connecting hole 6. The gasket 9 can be integrally formed during the casting of the valve body 1, which is convenient for manufacturing.

[0033] A washer 10 is fitted inside the groove 9. The washer 10 is made of rubber. The position of the groove 9 provides a positioning effect for the washer 10 when it is installed, improving the convenience of installation. The washer 10 can flexibly and wear-resistantly support the wear when subsequent components such as bolts are tightened.

[0034] Furthermore, the thickness of the washer 10 is greater than that of the groove 9 and is partially exposed, which can provide support when tightening larger bolts and other components, and has a good anti-wear effect.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
