Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically a novel five-way valve. Background Technology

[0002] In agricultural production, to ensure normal crop growth and achieve high and stable yields, it is essential to supply crops with sufficient water. Under natural conditions, insufficient or uneven rainfall often fails to meet the water requirements of crops. Therefore, artificial irrigation is necessary to compensate for the lack of natural rainfall. In farmland where agricultural irrigation water supply pipelines are installed, water is introduced into the fields when irrigation is needed, and the water supply is controlled by valves. However, most current control valves are single-inlet / single-outlet two-way valves or single-inlet / two-outlet three-way valves, which are inconvenient for branching the main water supply pipeline into multiple irrigation lines, resulting in inconvenience and low efficiency in diversion irrigation. Utility Model Content

[0003] In view of the problems existing in the prior art, this utility model discloses a novel five-way valve. The technical solution adopted is to use an integrally formed five-way structure shell, with a water inlet pipe in the middle of the shell. An air inlet is fixedly connected to the upper end of the water inlet pipe, and a one-way air inlet valve is fixedly installed on the air inlet. A first spherical valve body, a second spherical valve body, a third spherical valve body, and a fourth spherical valve body are respectively connected to the upper two sides of the water inlet pipe. Water pipe joints are respectively connected to the sides of the first spherical valve body, the second spherical valve body, the third spherical valve body, and the fourth spherical valve body. The first and second spherical valve bodies are connected and have a connecting liner installed in the middle of their inner cavities. The opening in the middle of the connecting liner is connected to the water inlet pipe. The openings at both ends are hemispherical and are respectively snapped together with hemispherical liners. The third and fourth spherical valve bodies are connected and have the connecting liner installed in the middle of their inner cavities. The opening in the middle of the connecting liner is connected to the water inlet pipe. The hemispherical liners are snapped together at both ends. A water outlet is provided in the middle of the hemispherical liners. The water outlet is snapped together with the water pipe connector. A valve core sealing ring is snapped together on the inner side of the water outlet. The connecting liner and the hemispherical liners are spliced ​​together to form an inner valve body, in which a valve core is installed by a rotating snap. The upper end of the valve core protrudes from the outer shell and is fixedly connected to a valve handle. Rotating the valve handle to turn the valve core causes the valve plate to engage with the valve core sealing ring, blocking the outlet. At this point, the valve is closed. Rotating the valve core 90 degrees disengages the valve plate from the valve core sealing ring, and the valve is fully open. Connect the inlet pipe to the water pipe, and connect the water inlet pipe to the water pipe connector. This opens the valve, allowing water to enter from the inlet pipe and flow out from the four water pipe connectors. A one-way air valve prevents water from flowing out. When the water pipe connected to the inlet pipe is closed, stopping the water supply, air is introduced into the inlet pipe through the one-way air valve, allowing the water inlet pipe connected to the water pipe connector to drain outwards, preventing negative pressure from forming in the inlet pipe and thus preventing water from draining from the water inlet pipe.

[0004] As a preferred embodiment of this utility model, the inner wall of the lower port of the water inlet pipe is provided with an internal thread to facilitate connection with the water supply pipeline.

[0005] As a preferred embodiment of this utility model, the valve core includes a valve plate, the outer side of which is spherical and fits the hemispherical inner liner and the inner side of the valve core sealing ring. A rotating connecting shaft is fixedly connected to the lower part of the valve plate, and a valve stem is fixedly connected to the upper end. The rotating connecting shaft and the valve stem are coaxial.

[0006] As a preferred embodiment of this utility model, the bottom of the inner valve body cavity formed by splicing the connecting inner liner and the hemispherical inner liner is provided with a snap-fit ​​groove, and the top is provided with a valve stem hole. The rotating connecting shaft is installed in the snap-fit ​​groove with a rotating snap-fit. The valve stem rotates through the valve stem hole and the outer shell and is fixedly connected to the valve handle.

[0007] The beneficial effects of this utility model are as follows: The outer shell of this utility model is integrally molded, and it is equipped with an inlet pipe for water intake and four outlet pipes connected to it. Each outlet pipe is equipped with a spherical valve body. An inner valve body is formed within the spherical valve body by splicing a connecting inner liner and a hemispherical inner liner, and a valve core is installed in conjunction with it, thus forming a five-way valve structure with one inlet and four outlets. The on / off state of each outlet pipe is controlled by the rotation of the valve core, thus facilitating independent control of the opening and closing of each outlet pipe. This valve structure facilitates the branching of multiple irrigation branch pipes from the water supply pipe, thereby improving the efficiency of water distribution irrigation. The branches are symmetrically arranged, ensuring uniform water output, and the independent on / off control of each branch makes operation convenient. Attached Figure Description

Detailed Implementation

[0015] Example 1

[0016] like Figures 1 to 6As shown, this utility model discloses a novel five-way valve, which adopts an integrally formed five-way structure outer shell 1. The middle part of the outer shell 1 is a water inlet pipe 101. The inner side wall of the lower port of the water inlet pipe 101 is provided with an internal thread 1011 for easy connection with the water supply pipeline. An air inlet 102 is fixedly connected to the upper end of the water inlet pipe 101, and a one-way air inlet valve 2 is fixedly installed on the air inlet 102. The upper two sides of the water inlet pipe 101 are respectively connected to a first spherical valve body 103, a second spherical valve body 104, a third spherical valve body 105, and a fourth spherical valve body 106. The sides of the first spherical valve body 103, the second spherical valve body 104, the third spherical valve body 105, and the fourth spherical valve body 106 are respectively connected to water pipe joints 107. A water pipe can be connected to the water pipe joints 107 to divert water to the location where irrigation is needed.

[0017] The first spherical valve body 103 and the second spherical valve body 104 are connected, and a connecting liner 5 is installed in the middle of their inner cavities. The opening in the middle of the connecting liner 5 is connected to the water inlet pipe 101, and the openings at both ends are hemispherical and are respectively snapped together with hemispherical liners 6. Similarly, the third spherical valve body 105 and the fourth spherical valve body 106 are connected, and the connecting liner 5 is installed in the middle of their inner cavities. The opening in the middle of the connecting liner 5 is connected to the water inlet pipe 101, and the hemispherical liners 6 are snapped together at both ends. A water outlet 60 is opened in the middle of the hemispherical liner 6. 1. The water outlet 601 is snapped into the water pipe connector 107. A valve core sealing ring 7 is snapped into the inner side of the water outlet 601. The connecting inner liner 5 and the hemispherical inner liner 6 are spliced ​​to form an inner valve body, and a valve core 4 is rotatably snapped into the inner side. The valve core 4 includes a valve plate 401. The outer side of the valve plate 401 is spherical and fits the inner side of the hemispherical inner liner 6 and the valve core sealing ring 7. A rotating connecting shaft 402 is fixedly connected to the lower part of the valve plate 401, and a valve stem 403 is fixedly connected to the upper end. The rotating connecting shaft 402 and the valve stem 403 are coaxial. The inner valve body cavity formed by splicing the connecting inner liner 5 and the hemispherical inner liner 6 has a snap-fit ​​groove 8 at the bottom and a valve stem hole 9 at the top. The rotating connecting shaft 402 is rotatably snapped into the snap-fit ​​groove 8. The valve stem 403 rotates through the valve stem hole 9 and the outer shell 1 and is fixedly connected to the valve handle 3, so that the valve plate 401 can rotate around the rotating connecting shaft 402 and the valve stem 403 inside the inner valve body.

[0018] When the valve core 4 is rotated by the valve handle 3, the valve plate 401 and the valve core sealing ring 7 are engaged, blocking the outlet 601. At this time, the valve is in the closed state. After rotating the valve core 4 ninety degrees, the valve plate 401 and the valve core sealing ring 7 are disengaged, and the valve is in the fully open state. The inlet pipe 101 is connected to a water pipe, and a water inlet pipe is connected to the water pipe joint 107, so that the valve core 4 is in the open state. Water enters from the inlet pipe 101 and flows out from the four water pipe joints 107 respectively. The one-way air inlet valve 2 can prevent the water from flowing out. When the water pipe connected to the inlet pipe 101 is closed and the water supply stops, air is introduced into the inlet pipe 101 through the one-way air inlet valve 2, so that the water inlet pipe connected to the water pipe joint 107 can drain water outward, avoiding the formation of negative pressure in the inlet pipe 101 that would prevent the water in the water inlet pipe from being discharged.
