Description

Technical Field

[0001] The utility model relates to the technical field of flow direction control valves, and more specifically to a liquid flow direction control valve. Background Art

[0002] A liquid flow control valve is a valve used to control the outflow direction of liquid. It can direct the liquid to the correct pipeline or equipment to achieve control and regulation of the flow direction of the liquid. There are usually three types of liquid flow control valves: angle flow control valve, straight-through flow control valve and ball flow control valve. The ball flow control valve structure consists of a valve body, a valve ball, a valve stem wrench and other parts;

[0003] However, the existing ball-type flow control valve lacks flow control and positioning measures when in use. For example, when a worker accidentally hits the wrench of the control valve, the wrench can easily drive the valve ball to rotate through the valve stem, thereby changing the direction of liquid flow inside the control valve and affecting the use of the control valve. This needs to be improved. Utility Model Content

[0012] Technical effects and advantages of the utility model:

[0013] 1.

[0023] In this embodiment, by providing the valve ball 21 and the L-shaped guide channel 22, it is convenient to guide the liquid at the liquid inlet 4 of the valve body 1. By providing the wrench 27 and the valve stem 25, it is convenient to rotate the valve ball 21 and the L-shaped guide channel 22, thereby adjusting the direction of the guide of the L-shaped guide channel 22 inside the valve ball 21, so that the liquid can be discharged into the first liquid outlet 5 or the second liquid outlet 6 of the valve body 1 through the L-shaped guide channel 22, thereby realizing the control of the liquid flow direction.

[0024] Embodiment 2:

[0025] like Figure 1-4 As shown, a flow control positioning mechanism 3 is provided above the valve body 1, and the flow control positioning mechanism 3 includes a positioning rod 31, the outer wall of the positioning rod 31 is movably sleeved on one side of the inside of the wrench 27, and a magnetic block 34 is fixedly embedded at the bottom of the positioning rod 31. A No. 1 positioning socket 35 is provided on the right side of the top of the valve body 1, and the No. 1 positioning socket 35 is located directly below the positioning rod 31. An No. 1 iron block 36 is fixedly embedded at the bottom of the inner cavity of the No. 1 positioning socket 35. A baffle 32 is fixedly sleeved at the bottom of the outer wall of the positioning rod 31, and an elastic wire 33 is movably sleeved on the outer wall of the positioning rod 31. The bottom end of the elastic wire 33 is fixedly connected to the top of the baffle 32, and the elastic wire 33 is fixedly connected to the top of the baffle 32. The top end of the force wire 33 is fixedly connected to one side of the bottom of the wrench 27, and a No. 2 positioning socket 37 is opened at the front end of the top of the valve body 1. A No. 2 iron block 38 is fixedly embedded at the bottom of the inner cavity of the No. 2 positioning socket 37. The No. 2 positioning socket 37 and the No. 1 positioning socket 35 are centered at a counterclockwise angle of 270 degrees with the middle of the top of the valve body 1 as the center. A No. 1 stopper rod 39 is fixedly connected to the right side of the top of the valve body 1, and the back of the No. 1 stopper rod 39 is overlapped on one side of the front of the wrench 27. A No. 2 stopper rod 391 is fixedly connected to the front end of the top of the valve body 1. The No. 2 stopper rod 391 and the No. 1 stopper rod 39 are centered at a counterclockwise angle of 270 degrees with the middle of the top of the valve body 1 as the center.

[0026] In this embodiment, the first stopper rod 39 and the second stopper rod 391 are provided to facilitate limiting the position of the wrench 27 during rotation. When the wrench 27 is located at the first stopper rod 39, the positioning rod 31 is pressed to insert the bottom end of the positioning rod 31 into the first positioning socket 35, and the magnetic block 34 is magnetically adsorbed with the first iron block 36 to fix the bottom of the positioning rod 31. At the same time, the positioning rod 31 is used to fix the wrench 27. At this time, the wrench 27 cannot drive the valve stem 2 5 and the valve ball 21 rotate. When the wrench 27 rotates 270 degrees counterclockwise, the wrench 27 can drive the valve ball 21 to rotate through the valve stem 25, thereby changing the diversion direction of the L-shaped diversion channel 22. At this time, the second stop rod 391 is used to limit and block the wrench 27, and the bottom end of the positioning rod 31 is inserted into the second positioning socket 37 in the same way, and the magnetic block 34 and the second iron block 38 are magnetically adsorbed together, and the wrench 27 can be limited and fixed again by the positioning rod 31.

[0027] In summary, if Figure 1-4As shown, this kind of liquid flow control valve, when in use, when the liquid needs to be discharged from the first liquid outlet 5 of the valve body 1, the wrench 27 is rotated to the back of the No. 1 stopper 39, and the positioning plug rod 31 is pressed downward, and the positioning plug rod 31 and the elastic wire 33 are stretched through the baffle 32, and the bottom end of the positioning plug rod 31 is inserted into the No. 1 positioning socket 35, and the magnetic block 34 and the No. 1 iron block 36 are magnetically adsorbed together, and the magnetic adsorption force of the magnetic block 34 and the No. 1 iron block 36 is greater than the resilience of the elastic wire 33. , to prevent the elastic wire 33 from driving the positioning rod 31 to rebound through the baffle 32, so that the bottom of the positioning rod 31 can be limited and fixed, and the wrench 27 can be limited and fixed by the positioning rod 31. At this time, the wrench 27 cannot drive the valve stem 25 and the valve ball 21 to rotate. When the liquid flows into the L-shaped guide channel 22 of the valve ball 21 through the liquid inlet 4 of the valve body 1, and flows into the first liquid outlet 5 through one end of the L-shaped guide channel 22, the flow direction of the liquid is controlled. When the liquid needs to be discharged from the second liquid outlet 6 of the valve body 1, the positioning rod 31 is moved upward so that the bottom end of the positioning rod 31 is moved out from the inside of the No. 1 positioning socket 35. At this time, the elastic wire 33 drives the positioning rod 31 to rebound through the baffle 32 to reset. Then the wrench 27 is rotated 270 degrees counterclockwise. The wrench 27 drives the valve ball 21 to rotate through the valve stem 25, so that one end of the L-shaped guide channel 22 rotates to the second liquid outlet 6, and the other end of the L-shaped guide channel 22 is located at the liquid inlet. At the opening 4, the wrench 27 is blocked by the No. 2 blocking rod 391, and then the bottom end of the positioning rod 31 is inserted into the No. 2 positioning socket 37 in the same way, and the magnetic block 34 and the No. 2 iron block 38 are magnetically adsorbed together, so that the positioning rod 31 is used to fix the wrench 27. At this time, the liquid flows into the L-shaped guide channel 22 of the valve ball 21 through the liquid inlet 4 of the valve body 1, and flows into the second liquid outlet 6 through one end of the L-shaped guide channel 22, so that the flow direction of the liquid is controlled.
