DETAILED DESCRIPTION

[0023] The utility model is described in detail below in conjunction with the accompanying drawings.

[0024] Embodiment: A pressure reducing valve with flow regulating function, see Figure 1-Figure 4 As shown, it includes a valve body 1, a valve bonnet 2, an adjusting bolt 3, a valve stem 4, a valve core 5, a piston 6, a pressure regulating spring 7, a fixing rod 9, a latch 901, a contact rod 10, an inlet pressure gauge 11, an outlet pressure gauge 12, a protective plate 13, a sealing ring 14, and an exhaust pipe 15. The valve bonnet 2 is installed on the valve body 1 through the adjusting bolt 3. The valve stem 4 is vertically slidably arranged on the upper part of the valve body 1. The valve stem 4 passes through the top of the valve bonnet 2 and is slidably connected thereto. The bottom of the valve stem 4 is connected to the valve core 5. The valve core 5 blocks the inside of the valve body 1. The valve core 5 can automatically adjust the flow and water pressure by moving up and down. The valve stem 4 is connected to a piston 6. The piston 6 is slidably connected to the valve body 1. A pressure regulating spring 7 is connected between the piston 6 and the valve bonnet 2. A card hole 8 is arranged in an array on the outer wall of the valve stem 4. The card hole 8 on the valve bonnet 2 is close to the card hole 8. A fixing rod 9 is connected to one side, and a latch 901 is slidably arranged inside the fixing rod 9. The latch 901 is inserted into the clamping hole 8, and the size of the clamping hole 8 is adapted to the size of the latch 901. The latch 901 clamps the valve stem 4 to fix the flow rate and water pressure. Contact rods 10 are welded symmetrically on the valve body 1. An inlet pressure gauge 11 with the value facing forward is threadedly installed on the contact rod 10 on the left side, and an outlet pressure gauge 12 with the value facing forward is threadedly installed on the contact rod 10 on the right side. A protective plate 13 is arranged in front of the inlet pressure gauge 11 and the outlet pressure gauge 12. The protective plate 13 is made of transparent material. Sealing rings 14 are arranged on both sides of the left and right sides of the valve body 1. The sealing ring 14 is used to prevent water leakage. An exhaust pipe 15 is connected to the right side of the upper part of the valve body 1, and the exhaust pipe 15 is arranged in an inverted L shape.

[0025] When the device is needed, people first install the device at the designated position so that the left and right sides of the valve body 1 are connected to the water inlet pipe and the water outlet pipe respectively, and the sealing ring 14 plays a sealing role to avoid water leakage. Then people pull the latch 901 outward so that the latch 901 no longer blocks the clamping hole 8. When water flows in to the right through the water inlet pipe on the left, the valve core 5 will move downward under the action of water pressure, so that it will no longer block the inside of the valve body 1, so that water can flow out to the right through the water outlet pipe. At the same time, the downward movement of the valve core 5 will drive the valve stem 4 to move downward, and the downward movement of the valve stem 4 will drive the piston 6 to move downward, and the pressure regulating spring 7 will stretch. When the water pressure changes repeatedly, the valve core 5 will repeatedly move up and down to achieve In order to automatically adjust the flow rate and water pressure, the exhaust pipe 15 is used to discharge the internal gas through the water outlet pipe. During use, people can know the water pressure values ​​of the water inlet and outlet by watching the values ​​displayed on the inlet pressure gauge 11 and the outlet pressure gauge 12. The protective plate 13 can play a protective role to prevent the values ​​and pointers on the inlet pressure gauge 11 and the outlet pressure gauge 12 from being damaged. When the flow rate and water pressure need to be fixed, people can manually push the valve stem 4 downward to drive the valve core 5 and the piston 6 to move downward. After moving to the appropriate position, push the pin 901 inward so that the pin 901 is reinserted into the clamping hole 8, and the valve stem 4 can be fixed, thereby achieving the purpose of fixing the flow rate and water pressure.
