The internal structure and working principle of the faucet

July 19, 2018

We use the faucet almost every day, but do you know the internal structure and working principle of the faucet? Let's take a look at the structure and working principle of the faucet today.

There are roughly three types of faucets commonly found in daily life: kitchen faucets, faucets for bathroom sinks, and bathtub faucets. The following explains the structure and principle of the faucet according to their different types.

1, vegetable basin faucet structure and principle:

The tap of the vegetable basin is mainly composed of a spiral valve core, and mainly relies on the rotation of the valve rod to generate a displacement through the thread to achieve the effect of opening and closing of the water inlet hole.

When we rotate the valve stem, the thread engages to advance and retreat the sealing end of the valve core. When we twist the valve core in, seal the inlet and seal the position of the outlet. Rely on the sealing end of the valve core and seal the outlet. To achieve alternating cold and hot water.

The working principle of the spiral valve core of the faucet is mainly through the rotation of the valve rod, so that the The thread is displaced to achieve the water hole switch. When we rotate the valve stem, the thread engages. The sealing end of the valve plug enters or retreats, and when it enters, the closing effect is achieved, and the retreating is the effect of the discharging water.

2, bathroom basin faucet structure and principle:

Simple basin faucet diagram, it is a single ceramic valve core surface, mainly composed of handle, valve core, water inlet braided pipe and installation gadgets.

Ceramic valve works:

In general, the bottom of the ceramic valve plug consists of three holes. One of the two holes is used to enter and exit the cold water, the other is used to enter and exit the hot water, and the remaining one is used to discharge the water inside the valve plug.

The cold and hot holes of the faucet valve core have seal rings to ensure that the oblique street of the main body is in a sealed state. After the cold and hot water inlet pipes are connected, the hot water pipe and the cold water pipe line correspond to the two holes of the valve core. The spool mainly controls the opening and closing state of the two holes, relying on the movement of the ceramic plate to work.

3, bath faucet structure and principle: The general bathtub faucet is through the S shift to make water into the main body, but first also have to enter the valve core, from the valve core into the main body. Water enters the body

The hole on the left side of the commutator achieves the opening and closing of the water flow by raising the commutator.

The commutator inside the faucet works as follows:

The commutator achieves the function of switching the bubbler and shower channel inside the main body through the seal ring and the main body. Note that in the commutator we see, the centerline must be symmetric, and if it is asymmetric, it will leak.
