[0023] See also Figure 1-5 The utility model discloses a three-way ball valve for a temperature and pressure sensor, comprising a valve body 4, wherein the valve body 4 is provided with an outlet 2 at the upper end, an inlet 1 at the lower end, and a pressure outlet 3 at the side, wherein the inlet 1, the outlet 2, and the pressure outlet 3 are interconnected; a rotatable valve ball 12 for connecting or closing a water channel between the inlet 1, the outlet 2, and the pressure outlet 3 is installed inside the valve body 4 and near the pressure outlet 3, wherein the outlet 2 has an internal thread, which is used to connect a temperature sensor, and the pressure outlet 3 is threadedly connected with a bushing 5, which is used to connect a pressure sensor.

[0024] Furthermore, the outlet 2 and the pressure outlet 3 open in the same direction.

[0025] Furthermore, the outer portion of the valve ball 12 is provided with a valve ball upper sealing gasket 10 and a valve ball lower sealing gasket 11 .

[0026] Furthermore, the outlet position of the pressure outlet 3 is provided with a second internal thread, and the second internal thread is used for threaded connection to the outside of the bushing 5 .

[0027] Furthermore, the bushing 5 has a hexagonal prism-shaped hole at its center which penetrates the bushing 5 longitudinally.

[0028] Furthermore, one end of a valve stem 8 is plugged and connected to the side of the valve ball 12 , and the valve stem 8 is fixedly connected to the handle 6 after extending out of the valve body 4 .

[0029] Furthermore, the valve body 4 and the handle 6 are fixedly connected via a handle fixing screw 7 .

[0030] Furthermore, the valve stem 8 is cylindrical, and a sealing ring 9 is sleeved on the outside of the cylinder. The sealing ring 9 is used to seal the portion where the valve stem 8 is connected to the valve body 4 .

[0031] Embodiment: The valve body 4 is in the form of a three-way. The lower opening is the inlet 1 of the fluid. There are two openings in the upper part, and the outlet 2 just above the lower part is used to install the temperature sensor. The other pressure outlet 3 is used to install the pressure sensor. The outlet 2 is threaded, and the temperature sensor or the water pipe is connected through the thread to block the liquid from flowing out of this outlet. The direction of the valve ball 12 can be changed by turning the handle 6 to connect or close the inlet 1 and the pressure outlet 3 to achieve fluid pressure detection.

[0032] The inlet 1 of the valve body 4 is provided with an external thread for connecting the liquid inlet channel. The valve ball 12 is a three-way ball. Compared with the valve ball with an L-shaped flow channel, the three-way form reduces the difficulty of processing and saves production costs. The liquid enters the inner cavity from the lower opening of the valve ball 12, and then passes through the valve ball upper sealing gasket 10 with a middle through hole. The other side hole is blocked by the valve ball lower sealing gasket 11, and no liquid flows out.

[0033] The valve ball 12 is connected to the valve stem 8 to achieve synchronous rotation of the valve ball 12 and the valve stem 8. The lower part of the valve stem 8 has an arc-shaped protrusion connected to the valve ball 12. The middle part of the valve stem 8 has two sealing ring grooves, and the top cylinder has a notch for matching and fixing with the groove on the handle 6. The top surface of the valve stem 8 is a threaded hole for installing screws to fix the valve stem 8 and the handle 6 as a whole.

[0034] The bushing 5 is threadedly connected to the valve body 4, and the thread is sealed by applying thread glue. The function of the bushing 5 is to apply pre-tightening force to the sealing gasket 10 on the valve ball, and further compress the valve ball 12. There is a hexagonal hole in the center of the bushing 5, which serves as a passage for the liquid to reach the pressure sensor after flowing through the valve ball 12. The hole is also the force hole of the hexagonal wrench for installing the bushing.

[0035] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
