Background

In daily life or production, the situation that the liquids need to be mixed is often encountered, and in general, the traditional valve can only meet the mixing mode between two liquids or only connect one liquid. If a plurality of liquids are mixed, the common solution is to connect a plurality of three-way valves in parallel. This way not only causes the waste of manufacturing cost, installation time, but also increases the difficulty of installation space and operation. The method has certain defects, and the actual operation control precision is not enough. In addition, the pipe fittings are complicated to connect, a premixing link is lacked, and the corrosivity of chemicals changed by chemical reaction after mixing lacks protective measures, so that the service life of the chemical medicines is shortened. To realize the mixing of various liquids, a plurality of valves are required to be connected in parallel, the occupied space is large, and the cost is increased.

Detailed Description

In the embodiment, referring to fig. 1 and 2, a control handle 2 is fixedly arranged at the top end of a valve rod 3 by a fastening screw 1, a sealing baffle plate 4 is fixedly arranged on a top plate at the upper end of an upper valve body 5 by a screw matched with the inner circumference of the upper valve body 5, and the valve rod 3 passes through a central hole of the sealing baffle plate 4. The rotary switch baffle 16 is fixed with the outer circumference of the valve rod 3, the valve rod 3 and the upper fan-shaped valve core 15 are of an integral structure, and the lower fan-shaped valve core 10 is arranged at the lower end of the valve rod 3 through a bearing. The connector 7 is arranged on the outer circumference of the lower fan-shaped valve core 10, the water inlet pipe positioning plate 13 is arranged on the inner circumference of the lower fan-shaped valve core 10, and the valve plate positioning column 17 is arranged on the upper surface of the upper fan-shaped valve core 15. The lower fan-shaped valve core 10 is connected with a lower water inlet pipe I9, a lower water inlet pipe II 18 and a lower water inlet pipe III 11 through a water inlet pipe positioning plate 13, and an upper valve body switch valve sliding groove 5-1 and a lower valve body switch valve sliding groove 12-1 are respectively arranged on the upper valve body 5 and the lower valve body 12. The external switch valve 14 is connected in the upper valve body switch valve sliding groove 5-1 and the lower valve body switch sliding groove 12-in a sliding mode, and the external water outlet pipe 14-1 is connected to the external switch valve 14. The upper valve body 5 and the lower valve body 12 are connected with a 360-degree water outlet baffle 6 through a sliding tenon-and-mortise structure, the inner circumferential surface of the lower end of the lower valve body 12 is in threaded connection with a connector positioning block 8, and an upper valve body scale 5-2 and a valve rod scale 3-1 are correspondingly arranged on the top cover of the upper valve body 5 and the valve rod 3.

The utility model discloses a working process is: when two kinds of liquid in the first inlet tube 9 and the second inlet tube 18 need to be mixed, the control handle 2 is rotated anticlockwise, the upper fan-shaped valve core 15 is aligned with the lower fan-shaped valve core 10, and the top plate of the upper valve body 5 is marked with scales. The control handle 2 is continuously rotated to enable the sector valve port to be arranged above the water inlets of the first water inlet pipe 9 and the second water inlet pipe 18. At the moment, the liquid of the first water inlet pipe 9 and the second water inlet pipe 18 are mixed in the valve body, and the handle 2 is rotated clockwise to enable the valve cores 15 and 10 of the upper fan-shaped opening and the lower fan-shaped opening to be staggered. The 360-degree water outlet baffle 6 is rotated to enable the water outlet to be aligned to the position of the external switch valve 14, a pipeline switch on the external water outlet pipe 14-1 is opened, the control handle 2 is pressed downwards to drive the valve rod 3 and the rotary switch baffle 16 to move downwards, the cavities of the upper valve body 5 and the lower valve body 12 are communicated with the 360-degree water outlet baffle 6, and mixed liquid is discharged. When the valve is closed, the control handle 2 is pulled upwards to drive the valve rod 3 and the rotary switch baffle 6 to move upwards, and the rotary switch baffle 6 closes the valve to form sealing. The need to mix inlet pipe one 9 with inlet pipe three 11 or inlet pipe two 18 with inlet pipe three 11 is consistent with the method of mixing the liquids in inlet pipe one 9 with inlet pipe three 11. If a single liquid in the first inlet pipe 9, the second inlet pipe 18 or the third inlet pipe 11 is needed, the fan-shaped opening is only needed to be aligned with one of the pipes, and the rest steps are the same as the liquid mixing method of the first inlet pipe 9 and the second inlet pipe 18.
