Description

Technical Field

[0001] This utility model relates to the technical field of regulating valves, and in particular to a heat dissipation type valve cover casting device for regulating valves. Background Technology

[0002] Electric control valves are crucial actuators in industrial automation process control. With increasing automation in industry, they are being used more and more in various industrial production fields. Compared to traditional pneumatic control valves, they have significant advantages: electric control valves are energy-saving (consuming electricity only during operation), environmentally friendly (no carbon emissions), and quick and easy to install (no need for complex pneumatic pipelines and air pump workstations). Valves are classified into three types according to the power used by their actuators, and based on their function and characteristics: linear, equal percentage, and parabolic. During the use of control valves, a heat-dissipating valve cover casting device is required.

[0003] However, existing heat dissipation valve covers are prone to internal shrinkage and crack defects. Compared with the heat dissipation fins of valve covers, there are more structures with thin and thick walls intersecting, and internal shrinkage and crack defects are prone to occur at the intersection. The tendency for solidification heat cracking is serious. Heat dissipation valve covers are pressure vessels and are prone to leakage during use, so the internal quality requirements of the product are high. Utility Model Content

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a casting device for a heat-dissipating valve cover of a regulating valve, including a riser 1, a heat-dissipating valve cover 2 installed on the lower surface of the riser 1, an inner sprue 3 fixedly connected to the lower surface of the heat-dissipating valve cover 2, a horizontal sprue 4 fixedly connected to the lower surface of the inner sprue 3, a straight sprue 5 fixedly connected to the outer surface of the horizontal sprue 4, and a sealing mechanism 6 provided on the lower surface of the inner sprue 3.

[0021] Furthermore, the sealing mechanism 6 includes a sleeve 61, a mounting frame 62, a receiving groove 63, a sealing ring 64, a mounting groove 65, a sealing gasket 66, and a fixing component 67. The sleeve 61 is mounted on the lower surface of the ingate 3. The mounting frame 62 is mounted on the inner surface of the sleeve 61. The receiving groove 63 is formed on the inner surface of the mounting frame 62. The sealing ring 64 is mounted on the inner surface of the receiving groove 63. The mounting groove 65 is formed on the outer surface of the mounting frame 62. The sealing gasket 66 is mounted on the inner surface of the mounting groove 65. The fixing component 67 is provided on the outer surface of the mounting frame 62. Through the arrangement of the sleeve 61, mounting frame 62, receiving groove 63, sealing ring 64, mounting groove 65, sealing gasket 66, and fixing component 67... The mounting frame 62 and its internal sealing structure are designed to effectively seal the connection between the ingate 3 and the runner 4, preventing liquid leakage during transport. The sleeve 61 is tightly connected to the lower surface of the ingate 3, providing stable support for the mounting frame 62 and its internal sealing structure. The receiving groove 63 inside the mounting frame 62 can accommodate the sealing ring 64. The elastic material of the sealing ring 64 allows it to fit tightly against the connecting end face of the runner 4, forming the first sealing barrier. At the same time, the sealing gasket 66 installed in the mounting groove 65 serves as the second sealing guarantee, further enhancing the sealing effect. The fixing component 67 is responsible for firmly fixing the entire sealing mechanism 6 to the mounting frame 62, preventing it from loosening or falling off during the casting process.

[0022] Furthermore, the fixing component 67 includes a semi-circular clamp 671, an anti-slip pad 672, a rotating shaft 673, a through-hole pad 674, a through hole 675, a bolt 676, a washer 677, and a nut 678. The semi-circular clamp 671 is mounted on the outer surface of the mounting frame 62, the anti-slip pad 672 is mounted on the inner surface of the semi-circular clamp 671, the rotating shaft 673 is mounted on the outer surface of the semi-circular clamp 671, the through-hole 674 is provided on the outer surface of the through-hole 674, the bolt 676 is provided on the inner surface of the through hole 675, the washer 677 is mounted on the outer surface of the bolt 676, and the nut 678 is mounted on the outer surface of the bolt 676. The mounting frame 62 is secured by the semi-circular clamp 671, the anti-slip pad 672, the rotating shaft 673, and the through-hole pad 674. The design of the through hole 675, bolt 676, washer 677, and nut 678 allows the semi-circular clamp 671 to tightly wrap around the outside of the mounting frame 62. The anti-slip pad 672 on its inner side increases friction with the mounting frame 62, ensuring the semi-circular clamp 671 is not prone to slipping or loosening after installation, thus enhancing stability. The rotating shaft 673 allows the semi-circular clamp 671 to open and close flexibly, facilitating installation and disassembly and improving operational efficiency. The through pad 674 and through hole 675 allow the bolt 676 to pass through, achieving a tight connection of the semi-circular clamp 671. The cooperation of the bolt 676 and nut 678 allows the clamping force on the semi-circular clamp 671 to be gradually increased by rotating the nut 678, ensuring the sealing mechanism 6 is firmly fixed to the mounting frame 62. Simultaneously, the washer 677 effectively disperses the pressure generated by the bolt 676, protecting the surface of the mounting frame 62 from damage and further enhancing the sealing and stability of the connection.

[0023] Furthermore, the outer surface dimensions of the mounting frame 62 match the inner surface dimensions of the sleeve 61, and the outer surface dimensions of the sealing ring 64 match the inner surface dimensions of the receiving groove 63. The sealing ring 64 enables the mounting frame 62 to be sealed.

[0024] Furthermore, the mounting grooves 65 are equally spaced on the outer surface of the mounting frame 62, and the outer surface dimensions of the sealing gasket 66 match the inner surface dimensions of the mounting grooves 65. The sealing performance of the mounting frame 62 can be increased by setting the sealing gasket 66.

[0025] Furthermore, the anti-slip pads 672 are installed at equal intervals on the inner surface of the semi-circular clamp 671, and the inner surface dimensions of the semi-circular clamp 671 match the outer surface dimensions of the sleeve 61. The anti-slip pads 672 increase the friction during installation.

[0026] Furthermore, the through pads 674 are installed symmetrically at equal intervals around the central axis of the semicircular clamps 671, and the outer surface dimensions of the bolts 676 match the inner surface dimensions of the through holes 675. The semicircular clamps 671 can be fixed by the bolts 676.

[0027] Furthermore, the outer surface dimensions of the bolt 676 match the inner surface dimensions of the washer 677. The bolt 676 and the nut 678 form a threaded structure. The nut 678 is designed to cooperate with the bolt 676 for fixing.

[0028] Working principle: It can effectively seal the connection between the ingate 3 and the runner 4 to prevent liquid leakage during transportation. The sleeve 61 is tightly connected to the lower surface of the ingate 3, providing a stable support for the mounting frame 62 and its internal sealing structure. The receiving groove 63 opened on the inner side of the mounting frame 62 can accommodate the sealing ring 64. The elastic material of the sealing ring 64 allows it to fit tightly against the connection end face of the runner 4, forming the first sealing barrier. At the same time, the sealing gasket 66 installed in the mounting groove 65 serves as the second sealing guarantee, further enhancing the sealing effect. The fixing component 67 is responsible for firmly fixing the entire sealing mechanism 6 to the mounting frame 62 to prevent it from loosening or falling off during the casting process.

[0029] The semi-circular clamp 671 tightly wraps around the outside of the mounting frame 62, while its inner anti-slip pad 672 increases friction with the mounting frame 62, ensuring that the semi-circular clamp 671 is not prone to slipping or loosening after installation, thus enhancing the stability of the fixation. The rotating shaft 673 allows the semi-circular clamp 671 to open and close flexibly, facilitating the installation and disassembly process and improving operational efficiency. The design of the through-hole 674 and through-hole 675 allows the bolt 676 to pass through, achieving a tight connection of the semi-circular clamp 671. The use of the bolt 676 and nut 678 allows the clamping force on the semi-circular clamp 671 to be gradually increased by rotating the nut 678, ensuring the sealing mechanism 6 is firmly fixed on the mounting frame 62. At the same time, the gasket 677 effectively disperses the pressure generated by the bolt 676, protecting the surface of the mounting frame 62 from damage and further enhancing the sealing and stability of the connection.
