A quick-opening valve exhaust muffler and its application method

Abstract

The present invention is applicable to the technical field of quick-opening valves, and provides a quick-opening valve exhaust silencing device and a method of use thereof, including a straight pipe part, a first silencing part, a telescopic pipe part and a second silencing part, the straight pipe part One end is connected with a connecting flange, the connecting flange is connected with the flange of the valve, the other end of the straight pipe part is connected to the front end of the first muffler part, the rear end of the first muffler part is connected to the front end of the telescopic pipe part, and the rear end of the telescopic pipe part The end is connected to the second muffler part, the second muffler part has muffler one, muffler two and muffler three, to realize the multi-stage exhaust noise reduction of the second muffler, and also includes telescopic pipe section, which can effectively absorb the exhaust of the device The huge impact force received during the process; the exhaust muffler device of the present invention can produce a relatively good muffler effect when discharging high-pressure gas, greatly reducing noise, and at the same time the muffler device can better absorb the impact force generated by air vibration and protect other components , and each component can be replaced, which improves the economy of the device.

Description

technical field [0001] The invention relates to the field of valves, in particular to an exhaust muffler device for quick-opening valves and a method of using the same. Background technique [0002] In the prior art, when the pressure of some pipeline systems is relatively large, the pipeline system has a fault or the high-pressure gas in the pipeline needs to be discharged in time, the usual operation method is to gradually operate the exhaust valve to slowly release the gas in the pipeline system. High pressure, if the pipeline pressure is released too quickly and the high pressure gas is discharged directly into the atmosphere, it will cause noise pollution and personal injury in an instant, and the exhaust device will be subjected to huge impact force, especially when the pressure in the pipeline exceeds 30Mpa , even when it reaches 38Mpa, the above-mentioned exhaust process may take as long as 30 minutes. Only in this way can the noise of the exhaust process not be too ...

[0002] In the prior art, when the pressure of some pipeline systems is relatively high, when there is a fault in the pipeline system or the high-pressure gas in the pipeline needs to be released in time, the usual operation method is to gradually operate the exhaust valve to slowly release the gas in the pipeline system. High pressure, if the pipeline pressure is released too quickly, the high-pressure gas will be discharged directly into the atmosphere, which will instantly cause noise pollution and personal injury, and the exhaust device will be subjected to a huge impact, especially when the pressure in the pipeline exceeds 30Mpa , even when it reaches 38Mpa, the above-mentioned exhaust process may take up to 30 minutes. Only in this way can the noise of the exhaust process not be too loud, and at the same time, it will not cause too much impact on the existing exhaust device, so as to avoid damage However, in the existing working conditions, there are working conditions that require rapid release of high pressure in the pipeline. When the system fails or is dangerous, the pressure in the pipeline needs to be released immediately, such as in Release the pressure to zero within 1 second. Although the existing valves will be properly equipped with certain noise reduction devices, most of the current noise reduction devices are single-stage noise reduction devices, and the noise reduction effect is poor. When the pressure is released, the huge impact force will also cause damage to the noise reduction device, which will affect the use effect of the noise reduction device, increase the cost of use, and the noise reduction effect is not ideal
