Description

Technical Field

[0001] The technical solution relates to the field of valve technology, and in particular to an integrated thermal insulation electric two-way ball valve. Background Art

[0002] A ball valve is a valve whose opening and closing parts are driven by a valve stem and rotate around the axis of the ball valve. It can also be used for regulating and controlling fluids. It can be controlled manually or electrically, or both.

[0003] Chinese patent CN220268752U discloses a valve combination at the water inlet and return ends of a fan coil unit, in which a shut-off valve and a regulating valve are connected via a first flexible joint structure. This connection structure has many leakage points and poor airtightness. Therefore, the present application makes improvements to the connection structure in order to obtain a valve with fewer leakage points and high airtightness. Summary of the invention

[0004] The purpose of this technical solution is to provide an integrated thermal insulation electric two-way ball valve, which solves the problem of many leakage points after the original valve is connected through a flexible joint structure by forming the ball valve pipeline and the electric valve pipeline into one piece.

[0005] The purpose of this technical solution is achieved in this way:

[0006] An integrated heat-insulating electric two-way ball valve comprises: a ball valve assembly, which comprises a ball valve pipeline; and an electric valve assembly, which comprises an electric valve pipeline; wherein the ball valve pipeline and the electric valve pipeline are integrally formed and communicated with each other.

[0007] Preferably, the front end of the ball valve pipeline and the rear end of the electric valve pipeline are both integrally formed with a live joint.

[0008] Preferably, the ball valve assembly further comprises: a valve stem, whose thread is arranged on the ball valve pipe; a valve handle, which is sleeved outside the valve stem; and a valve ball, which is arranged at the lower end of the valve stem and placed in the ball valve pipe.

[0009] Preferably, the electric valve assembly further includes: an electric valve switch, which is arranged on the electric valve pipeline; and an electric valve core, which is movably arranged at the lower end of the electric valve switch and is used to control the opening and closing of the electric valve pipeline.

[0010] Preferably, a mounting position is formed in the ball valve pipeline, and the valve ball is placed in the mounting position; ball valve sealing rings are arranged on both sides of the valve ball, and the ball valve sealing rings abut against the mounting position.

[0011] Preferably, the valve handle has an extension portion.

[0012] Preferably, the ball valve pipeline and the electric valve pipeline are covered with insulation sleeves.

[0013] Preferably, the ball valve further comprises a flexible joint, and the flexible joint is connected to the flexible joint interface through a nut.

[0014] Compared with the prior art, the technical solution has the following outstanding and beneficial technical effects:

[0015] 1. The ball valve pipeline of the ball valve assembly designed in this technical solution and the electric valve pipeline of the electric valve assembly are integrally formed, which can reduce the leakage points between the two and better ensure the overall sealing of the ball valve. In addition, a live joint is integrally formed at the front end of the ball valve pipeline and the rear end of the electric valve pipeline, which can further reduce the leakage points between the pipelines and further improve the sealing of the ball valve.

[0016] 2. The ball valve pipeline and electric valve pipeline designed in this technical solution can be covered with an insulation sleeve on the outside, so that the ball valve can be used in a high temperature and high humidity environment, increasing the applicability of the ball valve.

DETAILED DESCRIPTION

[0020] The specific implementation of the technical solution is further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1 and Figure 2 As shown, the purpose of the present application is to protect an integrated ball valve, which at least has a ball valve, an electric valve and a flexible joint. Forging the three as one piece can effectively reduce the number of leakage points between the three, thereby increasing the overall sealing of the ball valve. An integrated insulated electric two-way ball valve includes a ball valve assembly 1 and an electric valve assembly 3, which are forged as one piece without welds or splicing and are on the same horizontal line. Therefore, the fluid can flow through the ball valve assembly 1 into the electric valve assembly 3 and then flow out. At the same time, the two can work together to control the fluid. The ball valve assembly 1 is manually controlled, and the electric valve assembly 3 is electrically controlled.

[0022] Specifically, the ball valve assembly 1 includes a ball valve pipeline 2, a valve stem 6, a valve handle 7 and a valve ball 8. The valve handle 7 is arranged at the upper end of the valve stem 6, and the valve ball 8 is arranged at the lower end of the valve stem 6. The valve stem 6 is movably arranged on the ball valve pipeline 2 to control the up and down movement of the valve ball 8 to achieve the opening and closing of the ball valve pipeline 2; the electric valve assembly 3 includes an electric valve pipeline 4, an electric valve switch 9 and an electric valve core 10. The electric valve switch 9 controls the electric valve core 10 to rise and fall in the electric valve pipeline 4 to achieve the opening and closing of the electric valve pipeline 4.

[0023] Furthermore, the electric valve conduit 4 has a channel adapted to the lower end of the electric valve core 10. When the electric valve core 10 rises, the channel is open and the fluid can flow, and vice versa.

[0024] like Figure 1 and Figure 2 As shown, a mounting position 11 is formed inside the ball valve pipeline 2, and the valve ball 8 is movably placed in the mounting position 11. Ball valve sealing rings 12 are arranged on both sides of the valve ball 8, and the other side of the ball valve sealing ring 12 rests on the mounting position 11, which can effectively increase the airtightness of the valve ball 8.

[0025] like Figure 1 and Figure 2 As shown, the valve handle 7 has an extension portion 13, so the valve handle 7 is a high-position valve handle 7, which can be conveniently provided with a heat-insulating sleeve outside the ball valve, so that the ball valve can be used in a high-temperature and high-humidity environment.

[0026] like Figure 1 and Figure 2 As shown, the front end of the ball valve pipeline 2 and the rear end of the electric valve pipeline 4 are integrally formed with a flexible joint 5, and the flexible joint 5 can be connected to a variety of pipelines. Compared with other ball valves that need to connect the flexible joint 5 through a nut 15, this application has fewer leakage points and high sealing performance, so the connection method between the ball valve and the pipeline can be PPR or quick and easy, and various water tanks and water pumps can be connected through corresponding connecting threads.

When an element is referred to as being "connected to" another element, it may be directly connected to the other element or may be indirectly connected to the other element through an intermediate element.
