Problems solved by technology

Since the tipping bucket of the tipping bucket check valve itself has a counterweight, the cross-sectional area of ​​the check valve is relatively large, and the floor drain core formed by it cannot be used to make up for the above-mentioned defects of the floor drain due to its large volume.
The bucket type floor drain is therefore also not suitable for relatively small occasions

Embodiment Construction

[0013] The preferred embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0014] The pulley type tipping bucket or flap type check valve provided by the present invention, such as the pulley type tipping bucket check valve 100 shown in FIG. The first bucket 101 is connected with a first bearing 103, and the first shaft 104 of the first funnel 105 forms a first valve bearing pair to connect the first bucket 101 and the first funnel 105, so The first bucket 101 and the first funnel 105 of the seat 102 constitute a one-way valve; the seat 102 has a pulley 106 and a counterweight 107, and the pulley 106 and the seat 102 pass through the first pulley bearing pair connected, the pulley 106 has a groove 109, and the groove 109 is used to prevent the first wire rope 108 from falling off from the pulley 106; The pulley 106 is connected to the counterweight 107, and the counterweight 107 is used for the first du...

Abstract

The invention discloses a pulley type tipping-bucket one-way valve, which comprises a tip bucket and a base. The tip bucket is connected with the base through a valve bearing pair; the base comprises a hopper, and the tip bucket and the hopper form the one-way valve, wherein the base is provided with a pulley and a balance weight, the pulley is connected with the base through a pulley bearing pair, the tip bucket is provided with a projection which is connected with a cord, the cord rounds the pulley with a groove to be connected with the balance weight, and the balance weight is applied to the tip bucket to plug the hopper. The pulley type tipping-bucket one-way valve has small sectional area, thus the pulley type tipping-bucket one-way valve can be manufacture into a floor drain having smaller sectional area, and a floor drain core placed in a straight through floor drain and used for reforming a bell jar type floor drain. The pulley type tip bucket one-way valve can use a platform trap door to replace the tip bucket.

Description

technical field [0001] The invention relates to a pulley-type tipping bucket or flap-type one-way valve, in particular to a pulley-type tipping bucket-type one-way valve that drains water downwards and blocks upward movement of a medium, and is used in the fields of non-pressurized liquids and the like. Background technique [0002] In the process of human production and life, it is necessary to discharge the unpressurized liquid such as sewage on the ground downwards, and to block the odor of the medium such as the water pipe from rising up. The bell-type floor drains, straight-through floor drains with traps, and side wall floor drains that were widely used in the past did not form a water seal due to lack of water, or the water seal did not work due to the fluctuation of the gas pressure in the drain pipe, or absorbed water. And evaporation makes the water seal fail to block the sewer. The tipping bucket floor drain with tipping bucket check valve can drain smoothly and ...
