In this technical solution, the rotation of the handwheel drives the fixing screw to rotate and move downward, and the fixing screw moves downward while pressing the fixed valve stem and the adjusting nut, and the adjusting nut moves downward to compress the spring and drive the fixed valve stem and the diaphragm to move downward, and at the same time, the fixed valve stem moves downward to drive the movable valve stem to move downward synchronously, and the movable valve stem moves downward with the main sealing gasket synchronously, so that the main sealing gasket moves downward and contacts with the gasket seat, and the pressure relief port is closed, thereby achieving the effect of closing the pressure relief port. When performing maintenance, it is not necessary to close the main valve for maintenance, and by setting up three ports of one inlet and two outlets, it can meet the requirements of simultaneous installation of multi-functional outlets during use, which is convenient for installation and use.

[0004] However, the above technical solution does not facilitate the staff to check the opening and closing status of the valve body, which may cause the staff to make mistakes due to ignorance and cause confusion in the opening and closing of the valve body, thereby affecting the use effect of the technical solution. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a pressure reducing valve, and the opening and closing state of the valve body can be known by the position change of the detection plate. When the fluid medium flows through the stamping detection plate to move outward, the staff can know that the valve body is in an open state. On the contrary, when there is no position change of the detection plate, it indicates that the valve body is in a closed state. At the same time, with the help of the position change of the detection plate and the compression degree of the spring, the flow rate change of the fluid medium can be known, thereby improving the convenience of the staff in observing the opening and closing state of the valve body and the flow rate change, so as to solve the problems arising from the above-mentioned background technology.

When the fluid medium flows through the stamping detection plate and moves outward, the staff can know that the valve body is in the open state. On the contrary, when the detection plate does not change its position, it means that the valve body is in the closed state. At the same time, the change in the position of the detection plate and the degree of compression of the spring can be used to know the change in the flow rate of the fluid medium, thereby improving the convenience of the staff in observing the opening and closing state of the valve body and the change in flow rate;

[0016] 2. Through the threaded connection between the connecting ring and the fixed column and the supporting column, the connecting ring can connect and fix the fixed column and the supporting column to avoid the situation where the supporting column is suspended in the air without a supporting point. When the staff rotates the connecting ring to separate the supporting column, it is convenient for the staff to remove the supporting column, spring and detection plate, so that it is convenient for the staff to disassemble and replace the spring, thereby improving the convenience of the staff to replace the spring.

[0024] Refer to the instruction manual Figure 1-5 The utility model provides a pressure reducing valve, comprising a valve body 1 and a water inlet pipe 2 and a water outlet pipe 3 installed on both sides of the valve body 1, wherein the water outlet pipe 3 is provided with a functional component for conveniently checking the opening and closing state and the flow rate;

[0025] like Figure 2-5 As shown, the functional component includes a mounting seat 4, which is installed on the top of the water outlet pipe 3. A transparent visual box 5 is provided on the top of the mounting seat 4. Two spaced support columns 6 are provided inside the transparent visual box 5. The two support columns 6 are externally sleeved with the same detection plate 7, and the support columns 6 are externally sleeved with a spring 13; a through hole 8 is opened on one side of the top of the water outlet pipe 3 close to the mounting seat 4, and the bottom end of the detection plate 7 passes through the through hole 8 and extends to the inside of the water outlet pipe 3.

[0026] like Figure 4 and 5 As shown, both ends of the support column 6 are provided with a fixing column 9, and the fixing column 9 is installed inside one end of the transparent visual box 5. The fixing column 9 is close to the support column 6. One end of the fixing column 9 is externally threadedly connected with a connecting ring 10, and the end of the connecting ring 10 away from the fixing column 9 is sleeved on the outside of the support column 6. The end of the connecting ring 10 away from the fixing column 9 is threadedly connected with the external support column 6. A side plate 11 is provided on the side of the connecting ring 10 close to the support column 6, and the side plate 11 is sleeved on the outside of the support column 6. The end of the connecting ring 10 close to the support column 6 is movably connected to the side plate 11 through a bearing. The connecting ring 10 is threadedly connected with the fixing column 9 and the support column 6, so that the connecting ring 10 can connect and fix the fixing column 9 and the support column 6 to avoid the situation that the support column 6 is suspended without a supporting point. When the staff rotates the connecting ring 10 to separate the support column 6, it is convenient for the staff to remove the support column 6, the spring 13 and the detection plate 7, so that it is convenient for the staff to disassemble and replace the spring 13, and the convenience of replacing the spring 13 is improved.

[0027] like Figure 4 As shown, a plurality of fastening bolts 12 are provided on the outside of the bottom end of the transparent visual box 5, and the plurality of fastening bolts 12 are evenly spaced. The bottom ends of the fastening bolts 12 penetrate the transparent visual box 5 and extend to the inside of the mounting seat 4. The fastening bolts 12 are threadedly connected to the mounting seat 4. Through the threaded connection between the fastening bolts 12 and the mounting seat 4, it is convenient for the staff to install the transparent visual box 5 on the mounting seat 4, and it is also convenient for the staff to disassemble the fastening bolts 12 and remove the transparent visual box 5 for inspection and maintenance.

[0028] like Figure 4 and 5As shown, the width of the side plate 11 is greater than the diameter of the spring 13, and the end of the spring 13 away from the detection plate 7 is in contact with the side plate 11. By setting the width of the side plate 11 to be greater than the diameter of the spring 13, the side plate 11 can limit and fix the spring 13 to ensure the telescopic stability of the spring 13. The diameter of the fixing column 9 is equal to the diameter of the supporting column 6, and the inner diameter of the connecting ring 10 is equal to the diameter of the fixing column 9 and the diameter of the supporting column 6.

[0030] By setting the water inlet pipe 2 and the water outlet pipe 3, the fluid medium can circulate with the help of the opening and closing of the valve body 1. At the same time, in order to improve the staff's understanding of the opening and closing status of the valve body 1, it can be known through the position change of the detection plate 7. When the valve body 1 is opened to allow the fluid medium to circulate, the fluid medium flows and presses the detection plate 7 to move outward, so that the staff can know that the valve body 1 is in the open state. On the contrary, if there is no position change of the detection plate 7, it means that the valve body 1 is in the closed state. At the same time, with the help of the position change of the detection plate 7 and the compression degree of the spring 13, the flow rate change of the fluid medium can be known, thereby improving the convenience of the staff in observing the opening and closing status of the valve body 1 and the flow rate change.
