[0002] There are many types of safety valves on the market, which can be divided into spring-type safety valves, lever-type safety valves, etc. according to their structural forms. The design of these safety valves mainly focuses on the accuracy and reliability of their pressure control, but less on the convenience of installation and maintenance. In actual application, the installation and removal of safety valves often require the use of special tools, and in some narrow spaces, it is very inconvenient to operate. In addition, when replacing or repairing the safety valve, if appropriate measures are not taken, the safety valve may fall from a height, causing the risk of personal injury or equipment damage. Therefore, the existing safety valves have certain safety hazards during installation, removal and transportation. Summary of the invention

[0003] Purpose of the utility model: In order to improve the safety and convenience of the safety valve during installation, disassembly and transportation, it is necessary to improve the existing safety valve. The utility model provides a safety valve with a lifting hook, and in particular, adds a function of facilitating lifting in its structural design to reduce the risk of manual operation and improve work efficiency.

[0005] By adopting the above technical solution, by setting a lifting hook, it is convenient to use lifting equipment to install and disassemble the safety valve, reducing the need for manual operation, thereby reducing the risk of accidents caused by human factors, especially for safety valves with large diameters and large weights; and, the triangular cross-section of the lifting hook provides a stable and firm support point, while the arc-shaped groove increases the contact area between the lifting rope and the lifting hook, and guides the lifting rope to approach the outer peripheral surface of the valve cover, preventing the lifting rope from detaching from the lifting hook, making the lifting process more stable and reliable.

[0006] In a possible design, the lifting hook evenly distributed ring is arranged on the outer periphery of the valve cover and is arranged close to the top of the valve cover.

[0007] With the above design, the uniform distribution of the lifting hooks is conducive to the uniform distribution of the force on the safety valve during the lifting process, avoiding deformation or damage of the safety valve due to local uneven force; and the lifting hooks are arranged close to the top of the valve cover, which can be away from the main operating parts of the valve, reducing the possibility of collision with other pipelines or equipment during the lifting process, facilitating the operation of the lifting equipment, especially in an environment with limited space, it is easier to find a suitable lifting angle, making the lifting operation more convenient and efficient.

[0008] In a possible design, the lifting hook is integrally provided with reinforcing rib side plates on both sides along the circumferential direction of the valve cover, and the plate surface of the reinforcing rib side plates is perpendicular to the axial direction of the valve cover.

[0009] With the above design, the setting of the reinforced rib side plate increases the overall structural strength of the lifting hook, which can withstand a larger lifting load, thereby improving the stability and safety of the safety valve during the lifting process; and the reinforced rib side plate is perpendicular to the axial direction of the valve cover, which can effectively resist the bending moment generated during the lifting process, and avoid deformation or breakage of the lifting hook due to excessive load.

[0010] In a possible design, a ring is further provided on the outer periphery of the valve cover, the ring is coaxially arranged with the valve cover and integrally connected, and the cross section of the ring is "7"-shaped to form a rectangular groove between the ring and the outer periphery of the valve cover.

[0011] With the above design, the ring can be used as a mounting point for auxiliary lifting tools, which facilitates the use of other lifting tools to assist in adjusting the position or direction of the safety valve during the lifting process, ensuring that the safety valve is accurately installed in place, and the rectangular groove provides a stable mounting point for the lifting tool, thereby improving the lifting flexibility.

[0012] In a possible design, a plurality of in-groove reinforcing ribs are fixedly connected in the rectangular groove.

[0013] With the above design, the reinforcing ribs increase the structural strength of the ring, forming a more solid lifting structure.

[0014] In a possible design, a flange is provided at the bottom of the valve cover, a plurality of lifting ears are provided on the flange, lifting holes are provided in the lifting ears, the cross section of the lifting ears is triangular, and two sides of the lifting ears are respectively integrally formed with the flange and the valve cover.

[0015] With the above design, the lifting lug provides a lifting point at the bottom of the valve cover, which can lower the center of gravity of the lifting, which is beneficial to improving the stability of the lifting process, reducing the risk of shaking or tilting, and allowing the safety valve to select the most suitable lifting point according to different lifting requirements. It is suitable for a variety of lifting methods and different types of lifting tools. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] like Figure 1-4 A safety valve with a lifting hook is shown, comprising a valve cover 1, and a plurality of lifting hooks 2 are arranged on the outer periphery of the valve cover 1, and the lifting hooks 2 are integrally cast with the valve cover 1; the cross section of the lifting hook 2 is in the shape of a right triangle, and the right-angled side of the bottom surface of the lifting hook 2 is provided with an upwardly concave arc groove 21, and the arc groove 21 is adjacent to the outer periphery of the valve cover 1, so that the arc groove 21 is close to the surface of the valve cover 1, and the outer side of the arc groove 21 is convex, and the lifting rope is not easy to escape from the arc groove 21. The above-mentioned cross section refers to the cross section passing through the center of the valve cover 1, and the same applies to the following. The integrated design of the lifting hook 2 and the valve cover 1 simplifies the processing flow of the safety valve, does not require additional assembly, ensures structural strength, and improves manufacturing efficiency. Due to the special design of the lifting hook 2, the safety valve of the utility model is not only suitable for lifting operations under conventional environments, but also can adapt to the lifting needs in narrow or confined spaces, increasing the scope of application of the product.

[0022] The lifting hooks 2 are evenly distributed around the outer periphery of the valve cover 1 and are arranged close to the top of the valve cover 1. The number of lifting hooks 2 is preferably two to eight. If there are more than eight, the lifting effect is not obvious, and if there are less than two, it will be skewed. The lifting hooks 2 are arranged close to the top of the valve cover 1, which can keep the lifting tools away from the main operating parts of the valve, reducing the collision with other pipelines or equipment during the lifting process.

[0023] In order to enhance the overall structural strength of the lifting hook 2, reinforcing rib side plates 22 are integrally arranged on both sides of the lifting hook 2 along the circumferential direction of the valve cover 1, and the plate surface of the reinforcing rib side plates 22 is perpendicular to the axial direction of the valve cover 1. This improves the bearing capacity of the lifting load, and the setting direction of the reinforcing rib side plates 22 can improve the bending resistance of the lifting hook 2, avoiding deformation or fracture of the lifting hook 2 due to excessive load.

[0024] like Figure 2-4 As shown, a whole ring 3 is also provided on the outer periphery of the valve cover 1. The ring 3 is coaxially arranged with the valve cover 1 and connected as one piece. The cross section of the ring 3 is in the shape of a "7" to form a rectangular groove 31 between the ring 3 and the outer peripheral surface of the valve cover 1. Any position of the ring 3 can be used as a lifting point, mainly as a mounting point for auxiliary lifting tools, which is used to assist in adjusting the position or direction of the safety valve and facilitate flexible adjustment of the lifting operation. A number of groove reinforcing ribs 32 are fixedly connected in the rectangular groove 31 to strengthen the structural strength of the ring 3.

[0025] A flange 11 is provided at the bottom of the valve cover 1, and a plurality of lifting ears 4 are provided on the flange 11. A lifting hole 41 is provided in the lifting ear 4. The cross-section of the lifting ear 4 is in a triangular shape, and the two sides of the lifting ear 4 are respectively formed integrally with the flange 11 and the valve cover 1. The lifting hole 41 can be directly used for the connection of lifting tools, which simplifies the preparation work before lifting and improves the lifting efficiency. The lifting ear 4 provides a lifting point at the bottom of the valve cover 1, which can lower the center of gravity of the lifting, help to better control the posture of the safety valve during the lifting process, improve the stability of the lifting process, reduce the risk of shaking or tilting, and enable the safety valve to select the most suitable lifting point according to different lifting requirements, which is suitable for a variety of lifting methods and different types of lifting tools.
