the utility model provides a one-way drain valve for in water treatment plant's source water equalizing basin, includes tubular structure's valve body, the valve body bottom is equipped with the connector, connector department is connected with connecting portion, the valve body is inside to be hollow structure, and is equipped with the gravity closing cap in the valve body is inside, the upper end of valve body is connected with spacing closing cap, the valve body lower extreme is equipped with a plurality of horizontally distributed's apopore, gravity closing cap bottom covers on the connector.
Further, the surface of the connecting part is provided with an external thread.
Furthermore, the gravity closing cover is made of cement concrete.
Furthermore, the limiting sealing cover is in threaded connection with an opening at the upper end of the valve body.
Furthermore, the side wall of the gravity seal cover is abutted to the water outlet.
Furthermore, a rubber water stop ring is connected between the bottom end inside the valve body and the bottom of the gravity sealing cover.
Further, the anti-floating force of the gravity sealing cover is smaller than that of the bottom plate of the source water adjusting tank.
Furthermore, the connecting part is made of PVC material.
Furthermore, the valve body is made of PVC materials.
Furthermore, the limiting sealing cover is made of PVC materials.
Compared with the prior art, a one-way drain valve for in water purification treatment plant source water equalizing basin have following advantage:
a one-way drain valve for in water purification treatment plant source regulation pond set up the gravity closing cap in the valve body, rely on the gravity of gravity closing cap as the effort that the drain valve resets, and no longer rely on the spring, the device life is longer in the environment under water, also effectively prevents that source water regulation pond from receiving buoyancy too big and arousing structural damage, water source loss.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are used merely for convenience of description and for simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention. In addition, in the description of the present invention, "a plurality" means two or more unless otherwise specified.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
As shown in fig. 1, a one-way drain valve for a source water regulating reservoir of a water purification treatment plant comprises a valve body 3 with a tubular structure, wherein a connecting port is arranged at the bottom of the valve body 3, the connecting port is connected with a connecting part 1, the inside of the valve body 3 is of a hollow structure, a gravity sealing cover 5 is arranged inside the valve body 3, the upper end of the valve body 3 is connected with a limiting sealing cover 6, a plurality of water outlet holes which are horizontally distributed are arranged at the lower end of the valve body 3, and the bottom of the gravity sealing cover 5 covers the connecting port.
The surface of the connecting part 1 is provided with external threads.
The gravity seal cover 5 is made of cement concrete, and the material is stable, high in density and free of obvious change of gravity along with time.
And the limiting sealing cover 6 is in threaded connection with an opening at the upper end of the valve body 3.
The side wall of the gravity sealing cover 5 is abutted to the water outlet 4.
And a rubber water stop ring 2 is connected between the bottom end inside the valve body 3 and the bottom of the gravity seal cover 5.
