Problems solved by technology
The former relies on the floating ball to drive the lever to control the opening and closing of the overflow port. Its installation is complicated and the control position is inaccurate; the latter requires electricity and is matched with the water level control, which is expensive and low in reliability.

Embodiment Construction
[0011] As shown in the figure, the anti-leakage overflow valve of the present invention includes an overflow pipe joint 1 and a float 2. The float 2 is hingedly connected to the pipe joint 1, and the contact surface between the overflow pipe joint 1 and the float 2 is an inclined surface. The float is made of plastic or other lightweight materials to ensure that the float can open the nozzle of the overflow pipe joint 1 under the buoyancy of water, so that water can flow out of the overflow pipe joint.
[0012] Use status as figure 2 with image 3 As shown, P1 is the water level line and P2 is the overflow line. The position of the float when the water level is low, such as figure 2 , The overflow valve is closed to prevent the steam in the water tank from being lost to the outside. When the water level reaches a certain height, such as image 3 , The float is floated, the valve is opened, and the excess water is drained out of the water tank.

The invention discloses an air leakage resistance overflow valve comprising an overflow pipe joint. The invention is characterized in that a floater is hinged to the pipe orifice of the overflow pipe joint; the floater opens the overflow pipe orifice under the buoyancy action of water; since the contact surface of the overflow pipe joint and the floater is an inclined surface, the sealing effect of steam is good; the weight of the floater is well calculated and can prevent the water steam from scattering effectively; the height of the water level can be accurately reflected to the switching value of the valve at the same time; a block-shaped weighing body is arranged in the plastic floater; the floater is formed through the injection molding by adopting a mold; the sealing surface is smooth, and the integral shape and the weight are stable and reliable; the weight of the floater can be accurately controlled so that the overflow position of the overflow valve can also be accurately controlled; and the sealing surface is provided with a certain inclined angle, which is beneficial to the sealing and the opening of the floater according to the change of the buoyancy.
Description
Technical field: [0001] The invention relates to an overflow valve for a water tank, which is used to control the overflow of water. Background technique: [0002] The overflow port on the box generally does not need to be shielded or controlled. It is only needed to prevent the loss of heat and storage medium in a high temperature environment. The usual processing method is to use a lever float or an electric / electromagnetic control valve to achieve. The former relies on the floating of the floating ball to drive the lever to control the opening and closing of the overflow. Its installation is complicated and the control position is inaccurate; the latter requires electricity and is matched with the water level control, with high price and low reliability. Summary of the invention [0003] The technical problem to be solved by the present invention is to address the above-mentioned shortcomings of the prior art, and provide an anti-leakage overflow valve with convenient installat...
