[0001] The utility model relates to the technical field of valves, in particular to an anti-splash fitting for an exhaust valve. Background Art

[0002] It is generally necessary to install an automatic exhaust valve on the pressure-bearing integrated equipment for automatic exhaust in order to maintain the stable operation of the pressure inside the equipment and prevent the occurrence of safety accidents. The existing exhaust valve is provided with a blowout prevention structure to prevent the liquid in the equipment from being sprayed out by the exhaust valve, thereby ensuring the safety of the exhaust valve. However, when the exhaust valve is exhausting, scattered water will still be discharged from the exhaust hole of the exhaust valve. After the above-mentioned scattered water is discharged, a large area of ​​splashing and floating water will be formed near the exhaust valve, thereby affecting the surrounding environment and causing problems such as rust on nearby equipment. Since the scattered water is not in liquid but in gaseous state inside the equipment and the exhaust valve, it is converted into liquid as the ambient pressure changes after being discharged from the exhaust hole. Therefore, the existing blowout prevention structure inside the exhaust valve cannot prevent the discharge of scattered water.

[0003] In view of this, the inventor has designed a splash-proof accessory for an exhaust valve based on many years of production design experience in this field and related fields and after repeated experiments, in order to solve the problems existing in the prior art. Utility Model Content

[0032] The splash-proof accessory 100 of the exhaust valve proposed in the utility model is installed on the exhaust valve 200 through the connecting pipe 30. The high-pressure gas exhausted by the exhaust valve 200 enters the water collecting chamber 11 through the connecting pipe 30. After entering the water collecting chamber 11, as the ambient pressure decreases, the moisture in the high-pressure gas condenses in the water collecting chamber 11 and is then uniformly discharged through the drain port 12, thereby avoiding the scattered water generated by the exhaust valve 200 from forming large splashes and floating water near the exhaust valve.

[0033] The anti-splash accessory 100 of the exhaust valve proposed in the utility model can collect the scattered water generated by the exhaust valve 200 and discharge it in an organized manner, reducing the splashing of water around the exhaust valve 200 and the pollution and corrosion of the equipment, and the collected scattered water can be discharged into a return water pool or other wastewater collection pool through a drainage pipe, effectively saving water resources.

[0034] The splash-proof accessory 100 of the exhaust valve proposed in the utility model is also provided with a second shell 20 connected to the first shell 10, and the second shell 20 has an air replenishment port 22. When the exhaust valve 200 needs to be replenished with air, the replenishment air can be introduced into the drain port 12 of the exhaust valve 200 through the air replenishment port 22, the air replenishment chamber 21, the air vent 60, the water collecting chamber 11 and the connecting pipe 30, thereby realizing the air replenishment of the exhaust valve 200, and effectively avoiding the pollution that may be caused by water in the system when the surrounding environment is polluted during air replenishment.

[0035] In an optional embodiment of the utility model, the second shell 20 is sleeved outside the first shell 10, and an air-replenishing chamber 21 is formed between the inner wall of the first shell 10 and the outer wall of the second shell 20. The vent hole 60 is opened on the first shell 10, and the connecting pipe 30 seals and penetrates the second shell 20 and extends out of the second shell 20. With the above structure, the water collecting chamber 11 located in the first shell 10 and the air-replenishing chamber 21 located in the second shell 20 form an inner and outer chamber structure, the inner chamber (i.e., the water collecting chamber 11) collects water, and the outer chamber (i.e., the air-replenishing chamber 21) is ventilated, and steam-water exchange is achieved through the inner and outer chambers, ensuring that the condensed waste water flows out through the drain port 12, and the waste gas can flow out through the air-replenishing port 22, effectively separating the exhaust gas and the scattered water, and ensuring the normal operation of the exhaust valve.

[0036] In an optional example of this embodiment, a drain pipe 40 is connected to the outside of the drain port 12, one end of the drain pipe 40 is fixed to the drain port 12, and the other end of the drain pipe 40 is sealed and passes through the second shell 20 and extends outside the second shell 20, so that the collected scattered water can be discharged to the outside of the splash-proof accessory 100.

[0037] In an optional example, a first matching flange 41 is provided at the other end of the drain pipe 40, and the first matching flange 41 can be detachably connected to the drain pipeline to discharge the scattered water into a return water tank or other wastewater collection tank.

[0038] In an optional example of this embodiment, a second matching flange 23 is provided at the air supply port 22, and the second matching flange 23 can be detachably connected to the air supply pipeline, effectively avoiding possible contamination of water in the system when the surrounding environment is polluted during air supply.

[0039] In an optional embodiment of the present invention, the inner wall surface of the first shell 10 is an arc surface, which utilizes the condensation of water vapor and the diversion of condensed water.

[0040] In an optional example of this embodiment, the connecting pipe 30 and the drain port 12 are arranged adjacent to each other, and the airflow entering the water collection chamber 11 from the connecting pipe 30 is blocked by the inner wall of the first shell 10 opposite to the connecting pipe 30, and the water vapor condenses on the inner wall of the first shell 10, and then flows to the drain port 12 along the arc-shaped inner wall surface of the first shell 10, and the gas changes its flow direction along the first shell 10 and flows into the air replenishment chamber 21 from the multiple vents 60. In this embodiment, the connecting pipe 30 and the drain port 12 are arranged adjacent to each other, and the flow path of the condensed water along the first shell 10 is longer, which is conducive to the accumulation of the condensed water.

[0041] In an optional example of this embodiment, a drainage hole 70 is opened on the first shell 10, and the drainage hole 70 is set at the lowest point of the air replenishing chamber 21, so that the water that escapes into the air replenishing chamber 21 can flow back to the water collecting chamber 11 and be discharged in time, further improving the scattered water collection effect.

[0042] In an optional example, the vent hole 60 is disposed at a position of the first shell 10 adjacent to the drain port 12 or the connecting pipe 30 to extend the flow path of the gas in the water collection chamber 11 and also facilitate the condensation of water vapor.

[0043] In an optional embodiment of the utility model, the other end of the connecting pipe 30 has a radially protruding mounting step 31, and the mounting step 31 is detachably connected to the exhaust valve 200 by bolts. With the above structure, the mounting step 31 is used to replace the original top cover of the exhaust valve 200 (the exhaust port of the exhaust valve 200 is opened on the top cover), so that the gas discharged by the exhaust valve 200 directly enters the connecting pipe 30. The top cover is generally detachably mounted on the valve body of the exhaust valve 200 by bolts 210, and a reserved bolt hole that matches the bolt is opened on the valve body. Using the existing reserved bolt hole position, a mounting through hole that matches the reserved bolt hole is opened on the corresponding mounting step 31, and then the original bolts 210 of the exhaust valve 200 are used to install the mounting step 31, which effectively utilizes the existing conditions of the exhaust valve 200 and does not have a negative impact on the appearance or warranty of the original exhaust valve 200.

[0044] In an optional example of this embodiment, a sealing ring 32 is provided between the installation step 31 and the exhaust valve 200 to further ensure a sealed connection between the splash-proof accessory 100 and the exhaust valve 200 .
