[0003] A two-way valve is a type of valve that is designed to seal both medium flow directions. Current two-way valves regulate flow by the degree of valve opening and closing during actual use. This is also a common method used by many valves. However, this method is not enough for two-way valves. How to improve the comprehensiveness of flow regulation based on the degree of valve opening and closing is the problem to be solved by this application. Utility Model Content

The front side of the middle part of the channel is connected with a valve pipe, and the two ends are spliced ​​with the pipeline through the splicing flange and the splicing screw hole. Two mounting cylinders are fixed symmetrically on the top of the channel, and an operating button is installed on the top of the mounting cylinder in a rotating manner. A sealing sleeve is fixed on the side of the channel, and an adjusting button is installed on the outside of the sealing sleeve in a rotating manner. The adjusting button adjusts the flow rate of the valve pipe arranged in the channel. The flow regulating part is driven, and the sealing sleeve provides a sealing effect for the installation of the regulating button and the flow regulating part. Fixed plates are fixed on the left and right sides of the channel. The area between the two fixed plates on the left and the two fixed plates on the right corresponds to the valve plate. The valve plate is installed through a lifting mechanism. The lifting mechanism is driven by an operating button. The lifting mechanism is driven by the rotation of the operating button to drive the valve plate to rise and fall. A groove is opened on the top of the channel in the installation cylinder, and the valve plate extends into the channel from the groove. The valve plate descends and is inserted between the fixed plates to close and block the internal passage of the channel. When lifted, the channel passes the medium smoothly.

[0005] As a preferred technical solution of the utility model, an annular groove is opened on the wall of the splicing flange, and a sealing ring is arranged through the annular groove. The sealing ring is a rubber sealing ring to improve the sealing performance of the connection.

[0006] As a preferred technical solution of the utility model, anti-slip grooves are distributed on the side walls of the operating button to facilitate operation.

[0007] As an optimal technical solution of the utility model, the lifting mechanism includes a wing plate, a fixed column and a rotating stud. The wing plates are fixed on both sides of the top of the valve plate. The rotating stud is rotatably installed in the installation cylinder, and the fixed column is fixedly installed. The wing plates are respectively movably mounted on the fixed column and installed in cooperation with the rotating stud. The rotating stud is driven by an operating button.

[0008] As a preferred technical solution of the utility model, the flow regulating part includes a through groove, an adjustable baffle and an adjusting stud. The adjusting stud is rotatably installed on the side wall of the channel between the two fixed plates. The adjusting stud is driven by an adjusting button. An adjustable baffle is placed between the fixed plates and is installed in cooperation with the adjusting stud. The outer wall of the adjustable baffle is covered with a rubber layer, and the rubber layer fits tightly against the inner wall of the fixed plate.

[0009] The beneficial effects of the utility model: the valve plate is stably lifted and lowered by the lifting mechanism to cooperate with the fixed plate in the channel to realize the opening and closing of the pipeline. During use, the flow regulating part increases the range of flow regulation on the basis of utilizing the different lifting heights of the valve plate to realize flow control. During the actual use of the two-way valve, the regulation is more flexible and comprehensive, and the regulation of smaller flow changes can be achieved without operating the valve plate.

The front side of the middle part of the channel 1 is connected with the valve tube 101, and the two ends are spliced ​​with the pipeline through the splicing flange 2 and the splicing screw hole 3. Two mounting tubes 6 are fixed symmetrically on the top of the channel 1, and the operating button 7 is rotatably installed on the top of the mounting tube 6. A sealing sleeve 9 is fixed on the side of the channel 1, and an adjusting button 8 is rotatably installed outside the sealing sleeve 9. The adjusting button 8 drives the flow regulating part arranged in the channel 1. Fixed plates 14 are fixed on the left and right sides of the channel 1, and the area between the two fixing plates 14 on the left and the two fixing plates 14 on the right corresponds to the valve plate 10. The valve plate 10 is installed by the lifting mechanism, and the lifting mechanism is driven by the operating button 7. A groove is opened on the top of the channel 1 in the mounting tube 6, and the valve plate 10 extends into the channel 1 from the groove.
