The principle of the pressure release valve with the structure is as follows: when the pressure in the air inlet channel is larger than the pressure of the valve plate, the valve plate leaves the narrow opening, and the pressure in the air inlet channel enters the valve plate installation channel through the narrow opening and is released from the air release channel. The cover has a complex structure and high cost, and when the cover is applied to a normal pressure water tank, when the pressure in the normal pressure water tank is too large, the air leakage channel discharges water and releases pressure.
Disclosure of Invention
An object of the utility model is to provide a relief valve for water dispenser rational in infrastructure, with low costs.
The purpose of the utility model is realized like this:
the utility model provides a relief valve for water dispenser, includes the valve body, the valve body is equipped with inlet channel and loses heart passageway, its characterized in that: the air inlet channel points up and down, the air outlet channel is positioned above the air inlet channel and is communicated with the air inlet channel through a tapered hole, the tapered hole is narrow at the top and wide at the bottom, the inner wall of the tapered hole is provided with an air outlet groove, and the air outlet groove points up and down along the tapered surface of the tapered hole; the air inlet valve is characterized in that a silica gel ball and a supporting plate are arranged in the air inlet channel, the lower end of the air inlet channel is led out of the valve body, the silica gel ball and the supporting plate are sequentially arranged in the air inlet channel, air inlet holes penetrating through the upper end and the lower end of the supporting plate are formed in the surface of the supporting plate, the supporting plate is connected with the air inlet channel, and the silica gel ball is movably arranged on the supporting plate.
The purpose of the utility model can also adopt the following technical measures to solve:
more specifically, the air inlet holes are hexagonal and are arranged in the center of the supporting plate, and the supporting plate is in threaded connection with the inner wall of the air inlet channel. The hexagonal air inlet hole has the air inlet function, the hexagonal air inlet hole is convenient to be matched with a hexagonal screwdriver to conveniently screw the supporting plate, and the stroke of the silica gel ball can be changed by adjusting the supporting plate; the hexagonal shape of the structure is also considered to be equivalent if replaced by other hole patterns which can be matched with a screwdriver.
As a further scheme, the valve body is in an elbow shape, a hexagonal surface is arranged on the surface of the valve body corresponding to the outer wall of the air inlet channel, and an external thread is arranged on the outer wall of the lower end of the air inlet channel; the air release channel is transversely arranged and led to the outside of the valve body, and anti-skidding insections are arranged on the surface of the valve body corresponding to the outer wall of the air release channel.
As a further scheme, more than two air leakage grooves are arranged.
As a further proposal, the depth H of the air leakage groove is 0.3 MM. The air-escape groove of this depth is similar to a capillary tube, which is not conducive to water outflow, but the air pressure can thereby escape.
The utility model has the advantages as follows:
(1) the pressure release valve for the water dispenser only comprises the valve body, the silica gel ball and the supporting plate, and is simple in structure and convenient to install;
(2) the pressure release valve for the water dispenser is suitable for a normal pressure type heating container of the water dispenser, the air inlet channel of the valve body is connected with the top of the normal pressure type heating container, and the silica gel ball freely falls under the action of gravity and covers the air inlet hole of the supporting plate in a normal state, so that the air release channel is closed, the heat loss in the heating container is reduced, and meanwhile, dust is prevented from entering the heating container; when the water in the heating liner is heated to form pressure, and the pressure is greater than the gravity of the silica gel ball, the silica gel ball rises, the air inlet hole of the supporting plate is opened, and the air exhaust and pressure relief are realized; when the water level in the heating liner is contacted with the silica gel ball, the silica gel ball floats to be contacted with the taper hole, and only the air release groove is opened at the moment, so that the pressure can be continuously released.
