Description

Technical Field

[0001] The utility model belongs to the technical field of valve structures, and mainly relates to a valve combination structure for a crane pipe. Background Art

[0002] The crane pipe is a special equipment for loading and unloading materials into tank trucks. When in use, connect the end of the crane pipe to the interface on the tank truck, and then open the process valves and pumps on the pipeline to transport materials.

[0003] Depending on the location of the tanker connection, loading and unloading cranes can be divided into bottom loading and unloading cranes and top loading and unloading cranes. Bottom loading and unloading cranes are commonly used for loading and unloading petrochemical raw materials such as liquefied hydrocarbons and liquid ammonia. These raw materials rely on pressure filling, and the filling pressure is relatively high, generally between 1.2MPa and 2.5MPa.

[0004] The bottom loading and unloading crane pipe is connected to the tank truck with a quick connector at the end, and the liquefied hydrocarbon tank truck is connected to the tank truck with a KJB female end interface. The liquid hydrocarbon crane pipe is connected to the tank truck with a D-type female end quick connector. In order to seal the material inside the crane pipe, a ball valve is installed behind the quick connector. In practice, in order to reduce the labor intensity of the crane pipe operator, the quick connector and the ball valve are usually connected by a pipe thread, and the threaded connection itself has a great risk of loosening and falling off. The pipe section between the quick connector and the ball valve is affected by the processing machine tool fixture, and the length is generally greater than 100mm. Therefore, after being separated from the tank truck, a large amount of material is discharged into the atmosphere, thereby causing environmental pollution. Since the country is currently vigorously promoting energy conservation and environmental protection, the applicant has made corresponding improvements to the existing equipment, which can completely solve the above technical problems. Utility Model Content

[0005] In order to solve the technical problems in the background technology, the utility model provides a valve combination structure for a crane pipe, and the technical solution adopted is as follows:

[0006] A valve combination structure for a crane pipe includes a quick connector and a ball valve. The ball valve includes a valve core, a valve seal, a handle and a valve body. The valve seal is used for sealing. The valve core, valve seal and valve body are all made of corrosion-resistant materials to ensure the service life of the equipment.

[0007] The core improvement of the present invention is that the quick connector and the ball valve are fixedly connected by connecting bolts to form an integrated structure. This design completely solves the technical problem of traditional threaded connections being prone to loosening and falling off, and reduces the problem of material discharge into the atmosphere by shortening the distance between the quick connector and the ball valve. The above design ensures the safety of the equipment during use and reduces potential safety hazards.

[0008] Preferably, in order to quickly and safely transport materials, the quick connector is provided with a quick locking head.

[0009] Preferably, the handle is provided with a handle anti-rotation buckle, which is used to effectively lock the handle from rotating outside.

[0010] This new utility model addresses user pain points with an improved design, integrating the quick connector with the ball valve to eliminate the risk of the intermediate threaded connection falling off. It also shortens the length of the intermediate pipe, effectively reducing residual material discharge. During use, the utility model utilizes a welded connection to the crane pipe, ensuring safety and reliability.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0012] 1. Compact structure, minimizing the length of the pipe between the quick connector and the valve.

[0013] 2. High reliability, no short pipe section between the quick connector and the valve, avoiding the risk of leakage at the connection point.

[0014] 3. The quick connector adopts a safety locking pin with high reliability.

[0015] 4. The ball valve handle is equipped with an anti-rotation buckle to effectively prevent the handle from rotating outside the body.

[0016] 5. The connection with the pipeline is welded, which is safe and reliable. BRIEF DESCRIPTION OF THE DRAWINGS
