Background
The trace exhaust valve is a valve which is used for discharging trace air accumulated in a pipe in the pressure operation process of the pipe network and is an indispensable device for ensuring the normal and effective operation of a water supply pipe network.
Function of the micro-vent valve: when the water flow is full of the valve body of the micro exhaust valve, the micro exhaust hole is closed, so that the water in the pipe network is prevented from leaking. Along with the air is gathered at the upper part of the cavity of the valve body, water in the valve is replaced by the air, so that the liquid level of the water is gradually reduced, and when the liquid level is reduced to be insufficient for supporting the floating ball, the floating ball descends and opens the micro exhaust hole to release the gathered air. Along with the discharge of air, the water flow returns to the valve body cavity and acts on the floating ball, so that the exhaust hole is closed after the air is emptied, and the process is repeated in a circulating way.

Detailed Description
The invention is further described with reference to the following figures and examples.
This novel multisection lever trace discharge valve. As shown in figure 1, the valve comprises a valve cover 1, an exhaust plug 2, a sealing seat 3, a support 4, a lever I5, a lever II6, a lever III7 and a sealing piece 8.
The multi-section lever micro exhaust valve comprises a valve cover 1, an exhaust plug 2, a sealing seat 3 and a support 4.
The multi-section lever micro exhaust valve is characterized in that the central lines of the exhaust plug 2 and the sealing seat 3 on the valve cover 1 are superposed, and the sealing seat hole is communicated with the exhaust plug hole.
In the multi-section lever micro exhaust valve, the exhaust plug 2 and the sealing seat 3 are connected with the matched threads on the valve cover 1 through threads.
The multi-section lever micro exhaust valve is characterized in that the support 4 is provided with a lever I5, a lever II6 and a lever III7.
As shown in figure 2, the lever I5 is provided with a thread 5-1 connected with the floating ball; a fulcrum pin hole 5-2 connected with the bracket 4 is arranged; a pin shaft hole 5-3 connected with the lever II6 is arranged.
In the multi-section lever micro exhaust valve, as shown in fig. 2, a distance L1 from a center line of a floating ball connecting thread of the lever I to a center line of a fulcrum pin hole is greater than a distance L2 from the center line of the fulcrum pin hole to a center line of a pin hole connected with the lever II.
The multi-section lever micro exhaust valve is characterized in that, as shown in figure 3, the lever II6 is provided with pin shaft holes 6-1 and 6-2 which are respectively connected with the lever I5 and the lever III7.
As shown in figure 4, the lever III7 is provided with a pin shaft hole 7-1 connected with the lever II 6; a fulcrum pin shaft hole 7-2 connected with the bracket is arranged; a thread 7-3 is provided which is matched with the sealing element.
In the multi-section lever micro exhaust valve, as shown in fig. 4, a distance L3 between a central line of a pin shaft hole connected with the lever II and a central line of a fulcrum pin shaft hole on the lever III is greater than a distance L4 between the central line of the fulcrum pin shaft hole and a central line of a thread matched with the sealing element.
