[0022] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. Example 1
[0023] Please see Figure 1-5 As shown, a rain cap for a corrosion-resistant and low-temperature regulating valve that is easy to install includes a fixing base 1. The top of the fixing base 1 has an installation groove 2, and a spring 3 is movably connected to the inner side wall of the installation groove 2. One end of the spring 3 is movably connected to a fixing plate 4, and one side of the fixing plate 4 is movably connected to a pull rod 5, and one end of the pull rod 5 is movably connected to a connecting block 6.
[0024] One end of the pull rod 5 passes through the inner wall of the mounting groove 2 and is movably connected to one side of the connecting block 6, while the other end of the pull rod 5 passes through the spring 3 and is movably connected to one side of the fixing plate 4. This allows the operator to quickly install and disassemble the device, making it more convenient for the operator to inspect and replace the device, thus improving the practicality of the device for the operator.
[0025] In this embodiment, the coordinated use of the fixed base 1, mounting groove 2, spring 3, fixed plate 4, pull rod 5, connecting block 6, sealing ring 8, fixing ring 10, and fixing block 11 allows workers to quickly install and disassemble the device, making maintenance and replacement easier and improving its practicality. Furthermore, the sealing ring 8 ensures a tighter fit during installation, preventing air leakage and water ingress, further enhancing the device's usability.
[0026] In this embodiment, a pressure relief pipe 7 is movably connected to the inner wall of the fixed base 1, and a sealing ring 8 is movably connected to the top of the fixed base 1. An adapter 9 is movably connected to the top of the pressure relief pipe 7, and a fixing ring 10 is movably connected to the outer wall of the adapter 9. The use of the sealing ring 8 makes the device more tightly installed, preventing air leakage or water ingress from gaps during use, making the device more practical for workers and further improving its usability. Example 2
[0027] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution in which a fixing block 11 is movably connected to the bottom of the fixing ring 10, and the bottom of the fixing ring 10 is movably connected to the outer wall of the sealing ring 8. A rain cap body 12 is movably connected to the top of the adapter 9, and an extended brim 13 is movably connected to the bottom of the rain cap body 12.
[0028] The adapter 9 has an inclined vent 14 inside, and a dust baffle 15 is movably connected to the inner wall of the adapter 9. This allows the device to block rainwater when used by the staff. Furthermore, the use of the inclined vent 14 can effectively prevent the backflow of water condensed from the regulating valve, thus preventing water damage to the inside of the regulating valve and improving the practicality of the device during use.
[0029] In this embodiment, the rain cap body 12, the extended brim 13, the angled exhaust port 14, and the dust baffle 15 work together to keep rainwater out when the device is in use. The angled exhaust port 14 effectively prevents water condensation from flowing back into the regulating valve, thus preventing water damage to the inside of the regulating valve and improving the practicality of the device. The dust baffle 15 prevents external dust from entering the regulating valve when it is in the suction position, further improving the practicality of the device.
[0030] The working principle of the rain cap of this easy-to-install corrosion-resistant and low-temperature-resistant regulating valve will be explained in detail below.
[0031] When using the device, the operator first installs the fixing base 1 onto the outer wall of the pressure relief pipe 7, then aligns the fixing block 11 at the bottom of the fixing ring 10 with the mounting groove 2, and inserts the fixing block 11 into the mounting groove 2. When the fixing block 11 is inserted, it will push the fixing plate 4 and the spring 3 backward. When the fixing plate 4 moves backward to a certain position, the fixing block 11 can be inserted into the bottom of the mounting groove 2, and the fixing plate 4 will fix the fixing block 11. In this way, the device can be successfully installed. When the operator needs to disassemble the device, he only needs to pull the pull rod 5 through the connecting block 6. The pull rod 5 will drive the fixing plate 4 backward, so the operator can quickly inspect and replace the device. When the device is installed on the regulating valve, the condensed water from the water vapor can be discharged through the oblique exhaust hole 14, and there is also a dust baffle 15 to prevent dust from entering the regulating valve when air is intake.
