The outer side of the lower part of the rotating rod 6 passes through the upper part of the housing 10 and is fixedly connected with the first bevel gear 14. The outer side of the first bevel gear 14 is meshed with the second bevel gear 15. The inner side of the second bevel gear 15 is fixedly connected with a threaded rod 16. The outer side of the threaded rod 16 is spirally connected to the inner side of the baffle 13. In this way, the distance between the sealing gasket 31 and the water inlet network 9 can be accurately adjusted by utilizing the spiral connection between the threaded rod 16 and the baffle 13 and the meshing of the first bevel gear 14 and the second bevel gear 15. In order to solve the problem that traditional special valves with precision fine-tuning functions are generally controlled by circuits, which will increase the cost of use of the enterprise on the one hand, and on the other hand On the one hand, there is a problem that the turntable 8 cannot be used during a power outage. A positioning groove 17 is provided on the inner side of the turntable 8, and a telescopic rod 18 is slidably connected to the inner side of the turntable 8. A positioning block 19 is fixedly connected to the outer side of the telescopic rod 18, and the outer side of the positioning block 19 is slidably connected to the positioning groove 17. One end of a first spring 20 is fixedly connected to the inner side of the positioning groove 17, and the other end of the first spring 20 is slidably connected to the positioning block 19. A clamping block 21 is slidably connected to the inner side of the upper part of the turntable 8, and the lower part of the clamping block 21 is engaged with one end of the telescopic rod 18, and the other end of the telescopic rod 18 is flush with the outer end surface of the turntable 8. In this way, the clamping block 21 and the telescopic rod 18 can be engaged and disengaged, so that when the rotation resistance of the turntable 8 is too large, the telescopic rod 18 can be lengthened to lengthen the torque, thereby The resistance of the turntable 8 is reduced, and the practical performance of the entire device is improved. The upper end surface of the block 21 is fixedly connected to the handle 22, and the outer side of the handle 22 is fixedly connected to the handle sleeve 23 and the second spring 24. The other end of the second spring 24 is fixedly connected to the upper end surface of the turntable 8. The thickness of the handle sleeve 23 is 3 mm, which can facilitate the extension of the telescopic rod 18. The upper end surface of the arc-shaped protrusion 5 is fixedly connected to the sleeve rod 25, and the inner side of the sleeve rod 25 is inlaid with a first ball 26. The outer side of the first ball 26 contacts the rotating rod 6. The lower inner side of the fixed block 7 is inlaid with a second ball 27. The outer side of the second ball 27 contacts the upper end surface of the sleeve rod 25. In this way, the first ball 26 and the second ball 17 can be used to reduce the friction of the rotating rod 6 and improve the service life of the rotating rod 6.This reduces the company's operating costs and has good promotional value. There are two telescopic rods 18, positioning slots 17, positioning blocks 19, and first springs 20. The two telescopic rods 18, positioning slots 17, positioning blocks 19, and first springs 20 are symmetrically distributed on the left and right sides of the central axis of the clamping block 21. This makes the force on the entire device more balanced. The outer curved surface of the shell 10 and the inner curved surface of the arc-shaped raised portion 5 have the same curvature. The distance between the outer curved surface of the shell 10 and the inner curved surface of the arc-shaped raised portion 5 is 2 to 4 centimeters. The width of the baffle 13 is equal to the width of the sealing gasket 31. The width of the baffle 13 and the width of the sealing gasket 31 are both two-fifths of the width of the water inlet net 9. This makes the overall device more reasonable.

[0031] This embodiment also discloses a method for preparing a special composite valve, comprising the following steps:

[0032] Step 1: First, the valve body 1, the arc-shaped protrusion 5, the shell 10, the telescopic rod 18, the block 21 and the baffle 13 are stamped into shape; Step 2: Then, the first ball 26 and the second ball 27 are respectively installed on the inner side of the sleeve rod 25 and the fixed block 7, and the telescopic rod 18, the positioning block 19, the first spring 20 and the block 21 are installed on the inner side of the turntable 8; Step 3: Then, the heating plate 28 is embedded in the left part of the shell 10, the temperature detector 29 is installed on the left end surface of the shell 10, and the water inlet net 9 is fixed to the inner side of the right valve body 1 On the other side, fix the limit block 11 on the housing 10, fix the rotating rod 6 on the fixing block 7, and then pass through the sleeve rod 25, the arc-shaped protrusion 5 and the housing 10 in sequence, install the first bevel gear 14 and the second bevel gear 15, screw the threaded rod 16 into the inner side of the baffle 13, and then fix it on the second bevel gear 15; Step 4: Weld the left and right valve bodies 1 to the arc-shaped protrusion 5 respectively; Step 5: Install the controller 2, weld the flange 3 to the valve body 1, and finally open the mounting hole 4 on the flange 3.

[0033] Working process: Each component is connected to an external power supply when electricity is needed, and the device is controlled by the controller 2. When the special composite valve needs to be slightly adjusted, the turntable 8 is rotated, thereby driving the first bevel gear 14 to rotate with the cooperation of the first ball 26 and the second ball 27, and then driving the threaded rod 16 to rotate through the second bevel gear 15, and finally moving the baffle 13 and the sealing gasket 31, so that the gap between the water inlet net 9 and the sealing gasket 31 is changed, so that the flow inside the valve body 1 is better adjusted. When it is found that the resistance of the turntable 8 is too large during the rotation of the turntable 8, hold the handle 23 and pull the handle 22 to disengage the block 21 from the engagement with the telescopic rod 18. At this time, the telescopic rod 18 will extend outward under the elastic recovery of the first spring 20 and the auxiliary cooperation of the positioning block 19. At this time, the extended telescopic rod 18 can be used to rotate the turntable 8.

[0034] Example 2:

[0035] See also Figure 1-6 Based on Example 1, a heating plate 28 is fixedly connected to the inner left side of the housing 10, and a temperature detector 29 is fixedly connected to the left end face of the housing 10. The outer end face of the heating plate 28 is flush with the outer end face of the housing 10, thereby preventing ice from forming inside the valve body 1. When the temperature detector 29 detects that the water temperature is too low and may freeze, the controller 2 controls the heating plate 28 to start heating the water.
