Description

Technical Field

[0001] This utility model relates to the field of pressure gauge technology, and in particular to a fluid medium pressure gauge with a quick disassembly and assembly structure. Background Technology

[0002] Fluid pressure gauges are instruments that use elastic elements as sensing elements to measure and indicate pressures higher than ambient pressure. They are widely used in industrial process control and technical measurement. Due to the high mechanical strength and ease of production of the elastic sensing elements in mechanical pressure gauges, they are being used more and more extensively.

[0003] For example, patent application CN202420800332.7 discloses a fluid medium pressure gauge that is easy to install quickly. It includes a fluid pressure gauge body, a first pipe connection section, and a second pipe connection section. The bottom end of the fluid pressure gauge body is integrated with the first pipe connection section, and the middle part of the first pipe connection section is integrated with the second pipe connection section. One-way venting connectors are provided at one end of the first pipe connection section and one end of the second pipe connection section. The two one-way venting connectors are equipped with mounting pipes inside. The tail ends of the two mounting pipes are equipped with conical sealing sleeves. The soft rubber section in the middle of the two mounting pipes is equipped with a semi-circular limiting frame. This solution improves the speed of installation by setting mounting pipes, conical sealing sleeves, arc-shaped pressure plates, linkage pressure rods, and semi-circular limiting frames inside the one-way venting connectors, thus changing the traditional bolt installation method. In addition, the air-filled sealing ring and air-inflating section improve the sealing performance of the installation and prevent leakage.

[0004] The above-disclosed solution changes the traditional bolt installation method. Although it achieves the effect of quick installation, its sealing performance is poor. Air leakage during use of the inflatable sealing ring will increase the contact gap and affect the seal. Therefore, we designed a fluid medium pressure gauge with a quick disassembly and assembly structure. Utility Model Content

A first push rod is installed on the side of the threaded connection cover. A second push rod is installed at one end of the first push rod.

[0007] In the aforementioned fluid medium pressure gauge with a quick-release structure, a ball valve is installed at the end of the pressure gauge mounting tube, and a valve stem extending to the outside of the ball valve is installed at the ball valve core of the ball valve.

[0008] In the aforementioned fluid medium pressure gauge with a quick-assembly and disassembly structure, a pressure relief section interface post is sealed and connected to the valve port of the ball valve section. A sealing clamp is installed at one end of the pressure relief section interface post, and a pressure relief airbag is installed on the pressure relief section interface post through the sealing clamp. A one-way pressure relief port is provided at one end of the pressure relief airbag.

[0009] In the aforementioned fluid medium pressure gauge with a quick-release structure, an adjusting valve stem is installed at one end of the valve stem portion.

[0010] In the fluid medium pressure gauge with a quick-release structure described above, the second push rod extends and retracts relative to the first push rod, but the first push rod does not disengage from the second push rod.

[0011] In the aforementioned fluid medium pressure gauge with a quick-release structure, a pressure gauge dial is installed on the inner side of the fluid medium pressure gauge body, and an indicator needle is provided at the center of the pressure gauge dial.

[0012] The technical effects and advantages of this utility model are as follows:

[0019] This utility model provides, for example Figure 1-3 The figure shows a fluid medium pressure gauge with a quick-release structure;

[0020] Example 1: The pressure gauge includes a pressure gauge mounting tube 1 and a fluid medium pressure gauge body 4. A fastening nut 3 is installed on one side of the top end of the pressure gauge mounting tube 1. The fluid medium pressure gauge body 4 is connected to the pressure gauge mounting tube 1 through the fastening nut 3. A pressure gauge dial 18 is installed on the inner side of the fluid medium pressure gauge body 4. An indicator needle 17 is provided at the center of the pressure gauge dial 18.

A spiral fastening part 6 is installed on the inner side of the threaded connection cover 5. A first push rod 7 is installed on the side of the threaded connection cover 5. A second push rod 8 is installed at one end of the first push rod 7.

[0021] Specifically, the second push rod 8 extends and retracts relative to the first push rod 7, but the first push rod 7 does not detach from the second push rod 8. This design prevents the second push rod 8 from separating from the first push rod 7, thus ensuring a proper pushing effect on the threaded connection cover 5. Furthermore, the relative extension and retraction of the first push rod 7 and the second push rod 8 allows for changes in the lever arm, thereby facilitating easier and more labor-saving operation.

[0022] The above scheme sets up a second push rod 8 and a first push rod 7, and uses the first push rod 7 and the second push rod 9 to realize the rotational connection of the threaded connection cover 5, so as to achieve quick installation, good installation convenience, and easy disassembly.

The fluid medium pressure gauge body 4 is connected to the pressure gauge mounting pipe 1 through the fastening nut 3. A pressure gauge dial 18 is installed on the inner side of the fluid medium pressure gauge body 4. An indicator needle 17 is provided at the center of the pressure gauge dial 18. A pipe connection section 2 is installed in the middle of the bottom end of the pressure gauge mounting pipe 1. The pipe connection section 2 has a spiral installation structure. A ball valve section 10 is installed at the end of the force gauge mounting tube 1. A valve stem section 11 extending to the outside of the ball valve section 10 is installed at the ball valve core of the ball valve section 10. A pressure relief section interface post 12 is sealed and connected to the valve port of the ball valve section 10. A sealing clamp 13 is installed at one end of the pressure relief section interface post 12. A pressure relief airbag 14 is installed on the pressure relief section interface post 12 through the sealing clamp 13. A one-way pressure relief port 15 is provided at one end of the pressure relief airbag 14. An adjusting valve stem 16 is installed at one end of the valve stem section 11.
