When you push a beer tap forward, you are engaging the lever, which in turn controls the opening and closing of the internal valve within the faucet body. This valve is responsible for regulating the flow of beer from the keg to your glass.
The lever itself is a metal piece that is threaded to attach to the faucet knob or tap handle. It is strategically positioned to allow for easy operation and control of the beer flow. When you pull the tap handle forward, it pulls the lever forward as well, causing the lever to push the shaft of the internal valve backwards. This backward motion opens the valve, allowing beer to flow through the faucet and into your glass.
I remember the first time I used a beer tap and pushed it forward. It was during a brewery tour where we got the chance to pour our own pints. As I gripped the tap handle and pulled it towards me, I could feel the resistance of the lever before it engaged the valve. It was a satisfying click, and suddenly the beer started flowing smoothly into my glass. It was a simple yet exhilarating moment, knowing that I had control over the beer flowing into my glass.
Pushing the beer tap forward is a deliberate action that allows you to control the speed and amount of beer being dispensed. The further you push the tap handle forward, the more the lever pushes the valve shaft, resulting in a larger opening and a faster flow of beer. Conversely, if you only partially push the tap handle forward, the valve opens to a lesser extent, resulting in a slower flow of beer.
The responsiveness of the lever and the valve is crucial in ensuring a proper pour. A well-maintained and properly adjusted tap system will have a smooth and consistent flow of beer when the tap handle is pushed forward. This allows for a controlled pour, preventing excessive foam or spills.
In my experience as a brewer, I have encountered situations where a faulty or poorly maintained tap system resulted in inconsistent pours. Sometimes, pushing the tap forward would result in a sluggish flow or even no beer at all. This could be due to various factors such as a clogged or improperly adjusted valve, a worn-out lever, or even a damaged tap handle. It is important to regularly inspect and maintain the tap system to ensure optimal performance.
To summarize, pushing a beer tap forward engages the lever, which in turn opens the internal valve within the faucet body. This action allows for the controlled flow of beer from the keg to your glass. The responsiveness and proper maintenance of the tap system are key in achieving a smooth and satisfying pour.
