Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a high-stability, precision, large-flow angle valve. Background Art

[0002] In modern industry and daily life, angle valves play a vital role, especially in large-scale piping systems that require precise flow control or special application scenarios with extremely high stability requirements. With the development of science and technology, the demand for large-flow angle valves is increasing. These angle valves are often used for fluid transportation in chemical production, large-scale water supply systems or cooling systems of large mechanical equipment. These application scenarios require angle valves to maintain high stability under high flow to ensure the normal operation of the entire system.

[0003] The precision large-flow angle valve has a high-precision valve core and complex sealing components inside. In order to prevent leakage under high-flow impact and ensure its stability, its shell and connection parts are designed to be tighter. The tight shell design can ensure the sealing performance between the angle valve and the connecting pipe, effectively prevent medium leakage, and ensure the normal operation of the system.

[0004] However, traditional angle valves are often designed with an emphasis on accuracy and stability in flow control. For example, a special sealing gasket and an embedded connection structure may be used between the valve seat and the valve body, and the external threaded portion may be designed with a multi-layer anti-loosening structure. While these designs improve stability, they make it difficult to find a suitable fulcrum when disassembling the angle valve, and installation requires extremely high precision and complex operating steps. Moreover, when repairing or replacing the angle valve, this inconvenient disassembly and installation process consumes a lot of time and labor costs, seriously affecting the maintenance efficiency and normal operation time of the entire system. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a high-stability precision large-flow angle valve, which aims to improve the traditional angle valve design, which often focuses on the accuracy and stability of flow control, resulting in a lot of time and manpower costs when repairing or replacing the angle valve, thereby seriously affecting the maintenance efficiency and normal operation time of the entire system.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a high-stability, precision, large-flow angle valve, comprising an upper valve body and a lower valve body, both of which are provided with external threads, a four-leaf handwheel is provided on the upper surface of the upper valve body, a screw is fixedly connected to the inside of the four-leaf handwheel, an external hexagon is provided on the outer wall of the upper valve body, a clamping assembly is provided inside the external hexagon, the clamping assembly is used to rotatably clamp with the lower valve body, the clamping assembly includes a groove, the groove is provided inside the external hexagon, a clamping block is provided inside the external hexagon, the outer wall of the clamping block is slidably connected to the inner wall of the groove, a spring is fixedly connected to the inside of the clamping block, and one end of the spring is fixedly connected to the inner wall of the groove.

[0007] Furthermore, a clamping groove is provided inside the lower valve body, and the clamping groove is used for clamping with the clamping block.

[0008] Furthermore, a sealing disk is fixedly connected to the lower surface of the screw, and the outer wall of the sealing disk is slidably connected to the inner wall of the upper valve body.

[0009] Furthermore, an upper sealing ring is fixedly connected to the interior of the upper valve body, and the upper sealing ring is used to ensure that the angle valve does not leak when outputting.

[0010] Furthermore, a lower sealing ring is fixedly connected to the interior of the upper valve body, and the lower sealing ring is used to ensure the sealing of the angle valve when it is closed.

[0011] Furthermore, an internal thread is provided inside the four-blade handwheel, and the inner wall of the internal thread is threadedly connected to the outer wall of the screw.

[0012] Furthermore, the external thread is used to connect to water-using equipment.

[0013] Furthermore, a rotation groove is provided inside the upper valve body, and a docking groove is provided inside the upper valve body.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the utility model, by rotating the outer hexagon, it is rotated along the outer wall of the rotating groove. During the process, the card block is squeezed by the inner wall of the card slot, thereby realizing the card block moving inward into the groove. At the same time, the spring is squeezed and contracted by the card block until the card block is completely out of the card slot, thereby releasing the lock of the lower valve body. Then, the lower valve body is pulled out to realize the disassembly and maintenance of the angle valve. Then, the lower valve body is inserted into the docking groove until the card block can dock with the card slot. Then, the elastic action of the spring is restored, and the convenient installation of the angle valve can be realized, so that the operator can operate conveniently even in an environment with limited space, saving time and labor costs and improving maintenance efficiency.

[0016] 2. In the utility model, by rotating the four-leaf handwheel, the screw can be moved downward, and the screw drives the sealing disk close to the lower sealing ring, thereby reducing the water flow. The handwheel is turned to move the screw upward, and the sealing disk is away from the internal channel of the lower valve body and close to the upper sealing ring, thereby increasing the water flow. When the angle valve needs to be closed, the four-leaf handwheel is turned to allow the screw to drive the sealing disk downward. When the sealing disk is in full contact with the lower sealing ring, the angle valve can be closed. The setting of the two sealing rings greatly improves the sealing and fluidity of the angle valve.
