Detailed Description

As shown in fig. 1-3, an angle hydraulic system ball valve, including valve body 1 and three-

way valve ball

7, 1 top of valve body has bellied installation department 12, be equipped with again on the installation department 12 with three-way valve ball 7 linkage complex hand (hold) subassembly, installation department 12 lateral wall is equipped with the stiffening rib 13 of integral type structure. Installation department 12 is used for assembling the convenient control of hand (hold) subassembly and opens and close, and the protruding structure of installation department 12 is favorable to improving this department structural strength. The mounting portion 12 is designed to allow the valve rod 2 and other components to be mounted, and also has a limiting function to prevent excessive penetration. Here, reinforcing ribs 13 are also designed to further increase the structural strength.

The valve body 1 extends along the radial side face back to form a first connecting part 14 and a second connecting part 15 of an integrated structure, and the first connecting part 14 and the second connecting part 15 are located on the same axis but are respectively arranged at two ends of the valve body 1, which are opposite to each other in the radial direction. The design of the second connecting part 15 is convenient for assembling internal parts such as the three-way valve ball 7 and the like, so that the structure is simple and closed. In contrast, the first connecting portion 14 simplifies the assembly structure to ensure sealability and also prevents a series of problems. The first connecting portion 14 is connected with a lock nut 10 through threads and sleeved with an O-shaped sealing ring 11, the first connecting portion 14 is provided with external threads, and an annular groove 16 for installing the O-shaped sealing ring 11 is formed between the initial end and the tail end of the external threads. The first connecting part 14 is used for connecting other parts, and the lock nut 10 is designed to be beneficial to locking the O-shaped seal ring 11, so that the sealing performance is further improved, and the assembly and the use are convenient. After other parts are screwed tightly, the position of the O-shaped sealing ring 11 is adjusted and then locked by the locking nut 10. It should be noted that the lock nut 10 itself also serves a certain limiting function.

Threaded connection has valve cap 9 on the second 15 of connecting portion, connecting portion 14 communicates with each other with valve body 1 is inside to constitute the right angle valve way, the corner of right angle valve way in the valve body 1 is located to three-way valve ball 7. The inside is the valve way of right angle type, and three-way valve ball 7 sets up the control at the corner and opens and shuts. The bonnet 9 is provided with a regular hexagon rotating part 17, and the bonnet 9 is driven to be unscrewed through the rotating part 17.

The handle component comprises a valve rod 2, a sealing gasket 3, a pressing cap 4, a handle 5 and a nut 6 which are arranged in sequence. And sealing rings 8 are arranged between the three-way valve ball 7 and the first connecting part 14 and between the three-way valve ball 7 and the second connecting part 15, so that the sealing property is further improved, and local gaps can be filled. Valve rod 2 inserts installation department 12 and three-way valve ball 7 linkage cooperation, and valve rod 2 uses the axis as the center respectively with three-way valve ball 7 and handle 5 butt normal running fit, be equipped with on the three-way valve ball 7 with valve rod 2 linkage complex lead to groove 18, thereby valve rod 2 is in leading to 18 groove wall contacts butt rotations in groove. Likewise, the valve stem 2 and the handle 5 are also the abutting engagement structure, and are not illustrated or limited herein. The handle 5 is in threaded connection with the valve rod 2 through the nut 6 for clamping and limiting, and only the handle 5 is limited to be separated from the valve rod 2 in the axial direction.
