改良に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exhaust valve for automatically discharging air mixed in a water pipe, and more particularly to an exhaust valve which is connected to a float via a lever by utilizing the floating of a float housed in a valve chamber. The present invention relates to an improvement of an exhaust valve that opens and closes an exhaust hole with a valve body.

る。2. Description of the Related Art The basic structure of a conventional exhaust valve is that a valve chamber is formed in a valve casing with an inlet opening at a lower portion and an exhaust hole opened at an upper portion. The exhaust hole is opened and closed by a valve body connected to the float.

The valve body closes the exhaust hole via the lever. Then, when air flows into the valve chamber from the inflow port, the float loses buoyancy and descends, and the valve body opens an exhaust hole via the lever, and discharges air in the valve chamber from the exhaust hole. When water flows into the valve chamber due to the discharge of air, the float floats again, and the valve body closes the exhaust hole via the lever. Such an operation is repeatedly performed.

提供することである。However, in the above-described conventional exhaust valve, the valve closing force acting on the valve body is only the fluid pressure on the inflow side when the valve body is in the closed state where the exhaust hole is closed. In addition, there is a problem that the valve closing force is relatively weak, and valve leakage easily occurs. Therefore, a technical problem of the present invention is to provide an exhaust valve that does not cause valve leakage by increasing the valve closing force.

Then, the float is housed in the valve chamber, and the exhaust hole is opened and closed by a valve body connected to the float via a lever. When the valve body closes the exhaust hole, the upper surface of the float comes into contact with the lower end of the valve body. The valve body is pressed against the exhaust hole.

A lid 2 is screwed to the body 1 to form a valve casing having a valve chamber 3 therein. An inflow port 4 is formed in a lower portion of the main body 1, and a valve seat member 6 having an exhaust hole 5 is fixed to the lid 2 by a fastening nut 7, and the inflow port 4 is formed in a lower portion.
Is formed, and a valve chamber 3 having an exhaust hole 5 opened at an upper portion is formed.
The main body 1 has a thread 8 for connection around the inlet 4, and the valve seat member 6 has a connection 9 at the upper end.

排気孔５に押し付けるようにしている。[0008] A float 10 is accommodated in the valve chamber 3. A fulcrum 11 is provided at the lower end of the valve seat member 6, and one end of the lever 12 is swingably connected. A hemispherical valve body 13 for opening and closing the exhaust hole 5 is attached to the fulcrum 11 side of the lever 12 with a snap ring 14, and a connecting member 15 fixed to the float 10 is loosely connected to the other end of the lever 12. As shown in FIG.
When the valve 3 closes the exhaust hole 5, the upper surface of the float 10 abuts on the lower end of the valve 13 via the connecting member 15 to press the valve 13 against the exhaust hole 5.

き、弁漏れを生じることがない。The operation of the air vent of the above embodiment is as follows. FIG. 1 shows a state where water flows into the valve chamber 3 from the inflow port 4, the float 10 floats by receiving buoyancy, and the valve 13 closes the exhaust hole 5 via the lever 12.
In this state, the upper surface of the float 10 contacts the lower end of the valve 13 and presses the valve 13 against the exhaust hole 5, and the buoyancy of the float 10 acts as a valve closing force for the valve 13.
Therefore, the valve body 13 can reliably close the exhaust hole 5 by the fluid pressure on the inflow port 4 side and the buoyancy of the float 10, and no valve leakage occurs.

作動を繰り返して行う。When air flows into the valve chamber 3 from the inflow port 4, the float 10 loses buoyancy and descends, causing the lever 12 to descend.
The valve body 13 opens the exhaust hole 5 through the valve, and discharges the air in the valve chamber 3 from the exhaust hole 5. When water flows into the valve chamber 3 by discharging air, the float 10 floats again, and the valve 13 closes the exhaust hole 5 via the lever 12. Such an operation is repeatedly performed.

る。The present invention has the following specific effects. As described above, in the air vent according to the present invention, when the valve body closes the exhaust hole, the upper surface of the float contacts the lower end of the valve body to press the valve body against the exhaust hole, so that the buoyancy of the float closes to the valve body. Since it acts as a valve force, the valve closing force is increased, and an excellent effect that valve leakage does not occur is produced.
