The device you're looking for is called a vacuum regulator and sits between the vacuum source and the process. This page from Equilibar shows some examples and provides links that explain how they work. You can also use a vacuum breaker, which operates more or less like a pressure relief valve, but a vacuum regulator will offer more precise ...

2018年8月24日 · But if for other reasons (e.g. the tank being heated by sunlight) the pressure rises, the relief valve will disengage, releasing the excess build-up; a vacuum regulator works similar to the relief valve, except its set point is somewhere below 1 bar, while a typical relief (safety) valve will open when internal pressure rises considerably above ...

2017年10月18日 · A commercially available spring, with an OD of 9mm, a length of 19mm, and a wire dia. of 1mm has a rate of 3.15 N/mm, with 11.5 mm compression length. Putting the lowest possible regulator in front of your homemade regulator, set a large diaphragm across a 1m diameter expansion chamber.

$\begingroup$ Here is an example, look at this circuit, ibb.co/jjyPTK, if you replace the pressure relief valve with pressure regulator, then you have to set the outgoing pressure of pressure regulator to zero, it means no flow passes through the valve, even if the pressure exceeds the maximum allowed pressure in the circuit, if you set the outgoing pressure say to the maximum …

2021年7月9日 · Pilot operated valves have the limitation of only being able to shut off flow one direction and like you noticed they require a pressure above vacuum to stop flow. This site on vacuum valves mentions that they can be used for high flow vacuum applications, but there are some limitations. So depending on what vacuum pressures you are trying to ...

2021年7月14日 · (edit: Currently can't use a flow regulator in this application, any other suggestions instead of changing number of holes are welcome as well) I am not trying to achieve the exact same suction pressure for each area, but …

2019年10月20日 · I've done some calculations with the perfect gas law and got a volumetric flow rate of 415.943 SCCM based on the inlet pressure. The Cv's I've calculated thus far does not seem correct as they are very small numbers. I'm wondering how to properly choose a pressure regulator that can fit these parameters and how to calculate the Cv properly.

2023年2月13日 · You could use a pressure regulator on the inlet side, but you wouldn't want to. This would mean that your pump would always be working hard. When the inlet pressure is 200 bar, theoretically your compressor should have to do 0 work. A better solution would be to add some kind of control system to your compressor.

2020年2月2日 · It would be necessary to have an external vacuum pump to evacuate the air prior to the quick release. Auto tire houses use the reverse concept to seat a new tire on the rim. A cylindrical tank is loaded to substantial pressure by a compressor.

2024年2月21日 · $\begingroup$ There is a difference between "pressure loss" and "pressure difference". In order to get the fluid moving through a pipe with constant cross section, you need to create pressure difference. When the fluid is moving through the pipe, some of the internal energy is lost due to friction, which leads to pressure drop.
