Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically a 45° rotary three-way valve. Background Technology

[0002] The 45° rotary three-way valve (also known as a Y-type three-way valve or a 45° three-way ball valve) is a commonly used fluid control element used to switch flow paths, mix two fluids, or split a single fluid into two paths. Its core features are low flow resistance and good sealing performance.

[0003] However, the existing 45° rotary three-way valve still has shortcomings in terms of reliability, sealing performance, and ease of operation.

[0004] In view of this, we propose a 45° rotary three-way valve. Utility Model Content

[0005] The purpose of this utility model is to provide a 45° rotary three-way valve to solve the shortcomings of existing 45° rotary three-way valves mentioned in the background art, such as in reliability, sealing performance, and ease of operation. To achieve the above objective, this utility model provides the following technical solution: a 45° rotary three-way valve, including a valve body, the valve body being designed with a Y-shaped structure, valve sleeves being fixedly connected to the three ports of the valve body, and connection ports being connected through the axial centers of the three valve sleeves, a valve stem being connected through the interior of the intersecting side of the Y-shape of the valve body, and an electric rod being sleeved on one end surface of the valve stem.

[0006] Preferably, the valve seat inside the valve body is provided with a soft seal and a metal seal structure, and the valve stem adopts a multi-stage, combined packing structure.

[0007] Preferably, the connection between the valve body and the valve sleeve is a nested structure.

[0008] Preferably, the connection port includes a socket, the side surface of which is engaged with the axis of the valve sleeve, a main spring is fixedly connected inside the socket, a receiving groove bracket is fixedly connected to the other end of the main spring, a pressure sleeve is fixedly connected to the outer groove of the socket, a retaining ball is fixedly connected to the other end of the pressure sleeve, and a pressure rod is inserted into the inside of the socket.

[0009] Preferably, the valve stem includes a sleeve, with one side of the two sleeves connected through to the side of the valve body, and a valve shaft connected through to the one side of the two sleeves, with a branch rod fixedly connected to the side surface of the valve shaft.

[0010] Preferably, the electric lever includes a lever, one end of which is internally sleeved on the side surface of the valve shaft extending to the side of the valve body, the other end of which is connected to an arc rod, the other end of the top of the arc rod is connected to a moving seat, the other end of the moving seat is fixedly connected to a telescopic rod, and the other end of the telescopic rod is axially connected to a motor.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] In this invention, a double sealing structure is implemented on the valve seat sealing structure. The soft seal provides initial sealing, while the metal seal can still provide a certain sealing strength under high temperature conditions. The valve stem seal increases the depth of the stuffing box. The electric propulsion method avoids the need for force to open and close the valve, which could lead to excessive force or difficulty in handwheel operation after high pressure or long-term inactivity.

[0013] In this invention, the quick-replacement structure eliminates the need to replace the entire valve. The modular design allows for replacement without completely removing the valve from the pipeline, greatly reducing maintenance time and costs. Furthermore, the nested structure incorporates an anti-erosion design and optimizes the flow channel geometry. Attached Figure Description
