Embodiment 1

[0028] refer to Figure 1-Figure 6 , an automatic adjustment butterfly valve, including a valve ball 2, a water outlet connecting pipe 4 and a water inlet connecting pipe 8. The water outlet connecting pipe 4 and the water inlet connecting pipe 8 are respectively welded and fixed with the two ends of the valve ball 2. A rotating base 1 is welded and fixed to the bottom, respectively, the two rotating bases 1 at the top and the bottom are provided with connecting rod chambers 15, and a vertically arranged driving connection is sleeved between the two rotating bases 1 through bearings. The outer wall of the rod 11 and the driving connecting rod 11 is sleeved with a butterfly valve plate 10, and the butterfly valve plate 10 is located on the inner wall of the valve sphere 2, and a vertically arranged on-off valve mechanism is fixed between the two rotating bases 1 by bolts. One side of each rotating base 1 is provided with an on-off valve driving mechanism, a water resistance off...

Abstract

The invention belongs to the technical field of valve manufacturing, particularly relates to an automatic adjusting butterfly valve, and aims to solve the problem that an internal structure of an existing butterfly valve cannot counteract water resistance generated by closing the valve, and provides the following scheme that the automatic adjusting butterfly valve comprises a valve ball body, a water outlet connecting pipe and a water inlet connecting pipe; the water outlet connecting pipe and the water inlet connecting pipe are welded and fixed to the two ends of the valve ball correspondingly, rotating bases are welded and fixed to the top and the bottom of the valve ball correspondingly, and connecting rod cavities are formed in the two rotating bases located at the top and the bottom correspondingly. In the moving process of the water stopping block, the half range of the water inlet connecting pipe can be gradually closed, water impact resistance borne by the second butterfly valve half plate is offset, meanwhile, the switching valve driving mechanism operates to drive the butterfly valve plate to rotate and be closed, flow is guided through a water stopping inclined groove in one end of the water stopping block, and the sealing effect is good. And meanwhile, the water flow is guided in a backflow mode, so that the inflow water flow laterally impacts the second butterfly valve half plate.

Description

technical field [0001] The invention relates to the technical field of valve manufacturing, in particular to an automatic adjustment butterfly valve. Background technique [0002] The valve is a pipeline accessory used to open and close the pipeline, control the flow direction, and adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to its function, it can be divided into shut-off valve, check valve, regulating valve, etc. Among them, the butterfly valve is also called the flap valve, which is a kind of regulating valve with a simple structure. The butterfly valve that can be used for the on-off control of the medium in the low-pressure pipeline means that the closing member (disc or butterfly plate) is a disc, which rotates around the valve shaft to achieve opening and closing. A closed valve, in the current factory area, the use of butterfly valves gradually tends to be automated, and gradually tends to be unmanned manageme...
