Description

Technical Field

[0001] This utility model relates to the field of blank casting technology, and in particular to a valve cover blank casting. Background Technology

[0002] With the development of industrial manufacturing technology, such devices are used in the manufacturing and assembly of various fluid, liquid, and gas control equipment. As a key component in the valve system, the valve cover blank casting plays a role in sealing, supporting, and protecting. It is a preliminary form manufactured through the casting process and is usually not finished. Further processing is required to meet technical requirements. The blank casting not only provides the basis for subsequent processing, but also plays an important role in the design and manufacturing process, ensuring the overall quality and performance of the valve system.

[0003] Existing devices may not fully consider the fluidity and filling properties of materials during casting. For example, complex geometries may prevent molten metal from completely filling the mold cavity during casting, resulting in defects such as porosity and shrinkage. These defects weaken the strength and sealing of the casting. For valve cover blanks, this may lead to leakage or failure to withstand normal operating pressure during use. The structural shape of existing devices may also lead to uneven stress distribution, such as sharp corners or complex stress concentration areas. When subjected to external forces, these areas will bear excessive stress. Even under normal operating pressure, stress concentration may induce the formation of microcracks. As the service time increases, these cracks will gradually expand, eventually leading to the cracking of the casting. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a valve cover blank casting.

[0005] This utility model is achieved by the following technical solution: a valve cover blank casting, including a base, wherein a first reserved hole is provided inside the base.

[0006] Through the above technical solution, the base and its first reserved hole provide the basic structure for the entire device. The beneficial effect is that it provides a basic framework, which allows subsequent components to be connected to it. It is the starting point for the construction of the entire valve cover blank casting and lays the foundation for realizing the overall function of the device.

[0007] As a further improvement to the above solution, the base is made of cast iron.

[0008] The above technical solution uses cast iron as the base material. Cast iron has the characteristics of low cost, good wear resistance and excellent casting performance. Its beneficial effect is that while ensuring that the base has a certain strength, it reduces the manufacturing cost and can adapt to a certain working environment, thus ensuring the durability of the entire valve cover blank casting.

[0009] As a further improvement to the above solution, an arc-shaped outer shell is fixedly connected to the top of the first reserved hole, and a communicating outer shell is fixedly connected to the top of the arc-shaped outer shell.

[0010] Through the above technical solution, the top of the first reserved hole is connected to the arc-shaped outer shell, and the top of the arc-shaped outer shell is connected to the connecting outer shell. This connection structure constructs a material transmission channel. The beneficial effect is that a material transmission path from the base to the connecting outer shell is gradually constructed, enabling the material to flow between these components, and providing structural support for the entire device to realize the material transmission function.

[0011] As a further improvement to the above solution, the interior of the base is connected to the interior of the arc-shaped outer shell, and the arc-shaped outer shell is connected to the connected outer shell.

[0012] Through the above technical solution, the base is connected to the inside of the arc-shaped outer shell, and the arc-shaped outer shell is connected to the connected outer shell. The beneficial effect of this connection is to ensure that the material can flow smoothly between these components, and to avoid the increase of local pressure caused by the lack of structural connection.

[0013] As a further improvement to the above solution, a transmission channel is fixedly connected inside the communicating shell, and a semi-circular shell is fixedly connected to the back of the transmission channel.

[0014] Through the above technical solution, the internal structure of the outer shell is connected to the transmission channel, and the back of the transmission channel is connected to the semi-circular outer shell. The beneficial effect of this structure is that it further extends the path of material transmission. The semi-circular outer shell plays a role in protecting the transmission channel during the transmission process, while enriching the internal structure of the entire valve cover blank casting and providing a path for realizing the material transmission function.

[0015] As a further improvement to the above solution, a connecting plate is fixedly connected to the front of the transmission channel, and a second reserved hole is provided inside the connecting plate.

[0016] With the above technical solution, a connecting plate is connected to the front of the transmission channel, and a second reserved hole is set inside the connecting plate. The beneficial effect of this structure is that the transmission channel can be connected to other components through the connecting plate. The second reserved hole provides an interface for this connection, so that the entire valve cover blank casting can be integrated with other components to realize the overall function of the device, such as connection with external equipment or collaborative work with other functional components.

[0017] As a further improvement to the above solution, the connecting plate is made of cast iron.

[0018] The above technical solution uses cast iron as the material for the connecting plate, similar to the cast iron material for the base. Its advantages are that while ensuring the connecting plate has a certain strength, it reduces manufacturing costs and improves the economy and durability of the entire valve cover blank casting.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This invention utilizes a structure that incorporates threaded holes in the first and second pre-drilled holes on the base and connecting plate. The first pre-drilled hole is used for device fixation, while the second pre-drilled hole facilitates overall connection with other components. This structure ensures stable installation and effective connection with other parts. Furthermore, the connection between the arc-shaped outer shell, the connecting outer shell, and the transmission channel improves the internal flow of materials, thereby achieving stable installation and reliable connection with other components. This ensures that the entire device will not experience loosening or leakage during operation due to unstable connections, guaranteeing a tight seal.

[0021] This invention utilizes the unique geometric structure of the arc-shaped outer shell and the semi-circular outer shell to achieve the beneficial effects of reducing casting defects and improving the quality of the valve cover blank by taking advantage of the smoother flow of molten metal under these shapes during the casting process. Furthermore, it allows the casting to be subjected to external forces more evenly, reducing local stress and thus lowering the risk of deformation and cracking, extending the service life of the valve cover blank casting, and improving its operational reliability.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] Example:

[0031] Please combine Figure 1-5 The valve cover blank casting of this embodiment includes a base 1, and a first reserved hole 2 is provided inside the base 1.

[0032] The base 1 is made of cast iron.

[0033] An arc-shaped outer shell 3 is fixedly connected to the top of the first reserved hole 2, and a connecting outer shell 4 is fixedly connected to the top of the arc-shaped outer shell 3.

[0034] The interior of the base 1 is connected to the interior of the arc-shaped outer shell 3, and the arc-shaped outer shell 3 is connected to the connected outer shell 4.

[0035] A transmission channel 5 is fixedly connected inside the connecting shell 4, and a semi-circular shell 6 is fixedly connected to the back of the transmission channel 5.

[0036] A connecting plate 7 is fixedly connected to the front of the transmission channel 5, and a second reserved hole 8 is provided inside the connecting plate 7.

[0037] The connecting plate 7 is made of cast iron.

[0038] The implementation principle of a valve cover blank casting in this embodiment is as follows: During use, the first reserved hole 2 and the second reserved hole 8 on the base 1 and connecting plate 7 can be machined to create threads inside the first reserved hole 2 and the second reserved hole 8. At this time, the device can be fixed through the first reserved hole 2, and the entire assembly can be connected to other components through the second reserved hole 8. The substance, which may be liquid, gas, etc., enters from the base 1. Since the base 1, the arc-shaped outer shell 3, the connecting outer shell 4, and the transmission channel 5 are interconnected, the substance can flow along these channels, with the base 1 serving as the inlet. In some parts, the arc-shaped outer shell 3 and the connecting outer shell 4 play an initial guiding or stabilizing role for the incoming material. The arc-shaped outer shell 3 and the connecting outer shell 4 gradually guide the material flow to the transmission channel 5, thereby completing the seal. Furthermore, the arc-shaped appearance of the arc-shaped outer shell 3 and the semi-circular appearance of the semi-circular outer shell 6 are designed so that, during casting, the molten metal flows more smoothly due to the absence of sharp corners and overly complex geometry. This results in better filling of the casting and a lower defect rate during casting. At the same time, it optimizes the mechanical properties of the valve cover blank, enabling the force to be distributed along the curved direction when under stress. This makes the casting more uniform when subjected to external forces, reducing local stress and the risk of deformation and cracking.

[0039] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
