Description

Technical Field

[0001] The utility model relates to the technical field of valves, and more specifically to a heterosexual valve with a multi-path conduction structure. Background Art

[0002] Valves are control components in fluid delivery systems, with functions such as shutoff, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems come in a wide variety of varieties and specifications, from the simplest shutoff valves to the various valves used in extremely complex automatic control systems.

[0003] In the use of existing industrial valves, the valve is usually sealed by rotating the lifting rod so that the locking structure inside the valve blocks the valve port in a rotating or lifting manner. However, there are usually multiple locking structures for multi-channel valves, which need to be frequently opened and closed during use, and the operation is very cumbersome. In addition, the valve locking structure of some valves is prone to rust and damage due to long-term use, requiring frequent maintenance by staff, which reduces the work efficiency of the staff and the service life of the valve.

[0004] Therefore, in order to solve the above technical problems, the present application proposes a heterosexual valve with a multi-path conduction structure. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model aims to provide a heterosexual valve with a multi-path conduction structure.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a heterosexual valve with a multi-way conduction structure, comprising a valve cavity, a first channel and a second channel are respectively provided on both sides of the valve cavity, a third channel is provided below the valve cavity, a base flange connected to an external valve interface is provided at the lower end of the third channel, a ball opening valve rotatable in a horizontal circumferential direction is provided inside the valve cavity, a first opening is provided on the side of the ball opening valve, and a second opening is provided at the lower end of the ball opening valve.

[0007] Preferably, the first channel, the second channel, the third channel and the base flange are all provided with openings connecting the channels.

[0008] Preferably, the first opening can be alternately connected with the openings of the first channel and the second channel when rotating along the horizontal circumferential direction.

[0009] Preferably, a fastening structure is provided above the valve cavity, and a rotating handle is provided on the fastening structure. The rotating handle is connected to a connecting rod, and the connecting rod is fixedly connected to the upper end of the spherical opening valve inside the valve cavity. The fastening structure is used to fasten the connecting rod that can rotate inside the valve cavity.

[0010] Preferably, a gasket is provided at the connection between the openings of the first channel and the second channel and the ball opening valve. The gasket is made of sealing material to prevent liquid from leaking from the opening when the ball opening valve rotates.

[0011] Preferably, the base flange is provided with a flange hole, and bolts are inserted into the flange hole to fasten the base flange to the external interface, and the connection between the first channel, the second channel and the valve cavity is fixed by bolts.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. In the utility model, by loosening the fastening structure and then rotating the rotating handle, the rotation of the rotating handle can drive the ball opening valve connected to the rotating handle to rotate in a horizontal circular direction, thereby driving the first opening on the side of the ball opening valve to rotate inside the valve cavity. When the first opening rotates to the opening of the first channel, the ball opening valve is connected to the first channel, and the liquid or gas required to pass can enter the first opening through the first channel, and then pass through the interior of the ball opening valve to the second opening, and finally pass through the third channel to the external interface, thereby realizing the function of a single locking control three-channel valve, with a simple structure, no need for frequent maintenance by staff, simple operation, and improved work efficiency of staff.

[0014] 2. In the utility model, when the valve does not need to be reversed, the nut in the fastening structure is tightened so that the handle cannot be rotated, thereby preventing the valve from suddenly reversing when the valve does not need to be reversed, causing economic losses. At the same time, by controlling the locking and loosening functions of the fastening structure, the flow rate of the fluid inside the valve cavity can be controlled, thereby playing a role in controlling the flow rate.

[0022] It should be noted that: the first channel 2, the second channel 3, the third channel 4 and the base flange 5 are all provided with through openings 6 connecting the channels. The first opening 8 can be alternately connected with the through openings 6 of the first channel 2 and the second channel 3 when rotating along the horizontal circumferential direction. A gasket 10 is provided at the connection between the through openings 6 of the first channel 2 and the second channel 3 and the ball opening valve 7.
