First, as shown in fig. 1, in the present embodiment, a valve body 1 includes: the inlet pipe 11 and the outlet pipe 12 are disposed opposite to each other, the inlet pipe 11 has a first inlet end 111 and a first outlet end 112, and the outlet pipe 12 has a second inlet end 121 and a second outlet end 122, and the second inlet end 121 is higher than the first outlet end 112 along the first axial direction.
Next, as shown in fig. 1, the balance sleeve 2 is disposed in the valve body 1 along a first axial direction a, and at the same time, the balance sleeve 2 opens a water passage 21 communicating with the second water inlet end 121 along a second axial direction B, and in the present embodiment, as shown in fig. 1, the second axial direction B is perpendicular to the first axial direction a.
As shown in fig. 1, in the present embodiment, the valve flap 3 is provided in the valve body 1 along the first axial direction a, and the valve flap 3 is partially inserted into the balance sleeve 2. In addition, along the first axial direction A, the valve flap 3 is provided with a groove 31 from bottom to top, and along the second axial direction B, the valve flap 3 is provided with a water through hole 32 communicated with the groove 31, and the valve flap 3 is separated from the valve body 1 to form a flow channel 13 communicated with the first water outlet end 112. Meanwhile, the valve flap 3 is slidable in the first axial direction a and serves to connect or disconnect the flow passage 13 and the water passage 21.
Further, as shown in fig. 1, the valve stem 4 is inserted into the valve body 1 in the first axial direction a and connected to the valve flap 3. And a driving assembly 5 is connected to the valve stem 4, the driving assembly 5 being adapted to drive the valve stem 4 to perform a linear movement in the first axial direction a.
It can be seen from the above description that in practical applications, as shown in fig. 1, when the driving assembly 5 drives the valve rod 4 to lift the valve flap 3, the flow channel 13 can communicate with the water outlet pipeline 12 through the water passage 21, and the valve flap 3 can control the cross-sectional area of the water passage 21 during the lifting process to achieve the adjustment effect on the medium flow. When the driving component 5 drives the valve rod 4 to make the valve clack 3 descend to the limit position, the valve clack 3 can cut off the communication relation between the water passage 21 and the flow passage 12 again to achieve the function of cutting off the pipeline. Therefore, the stop regulating valve of the embodiment can realize the functions of throttling and regulating and can also realize the function of cutting off the pipeline, thereby not only simplifying the design of a pipeline system, improving the utilization rate of space, but also reducing the design and production cost of the pipeline.

In the outlet conduit 12, the second inlet end 121 is higher than the second outlet end 122. Therefore, the design requirement that the second water inlet end 121 is higher than the first water outlet end 112 can be met, so that the stop regulating valve of the embodiment can simultaneously realize the flow regulation of the medium and the cutting-off function of the pipeline.
Further, as shown in fig. 1, the cutoff adjustment valve according to the present embodiment further includes: a valve cover 6 and a guide mechanism 7 which are arranged on the top of the valve body 1 along the first axial direction A. In order to satisfy the driving of the valve rod 4 by the driving unit 5, in the present embodiment, as shown in fig. 1, the driving unit 5 includes: the valve rod nut 51 is rotatably arranged in the valve cover 6 and is penetrated by the valve rod 4, the valve rod nut 51 is further in threaded connection with the valve rod 4, in addition, the hand wheel 52 is arranged at the top of the valve cover 6 and is connected with the valve rod nut 51, and the hand wheel 52 is used for driving the valve rod nut 51 to rotate, so that the valve rod 4 can be in threaded connection with the valve rod nut 51, and linear motion along the first axial direction A is realized under the rotating action of the valve rod nut 51, and then the lifting motion of the valve clack 3 in the valve body 1 is completed.
In addition, in order to prevent the valve rod 4 from rotating when the valve rod 4 moves linearly along the first axial direction a, the guide mechanism 7 is disposed on the valve rod 4 and is connected with the bonnet 6 in a sliding manner along the first axial direction a.
Specifically, in the present embodiment, as shown in fig. 1, the guide mechanism 7 includes: a positioning block 71 and a positioning pin 72. The positioning block 71 is sleeved on the valve rod 4, the positioning pin 72 is detachably connected with the positioning block 71 along the second axial direction B, in addition, the valve cover 6 is provided with a slide way 61 along the first axial direction A, and the positioning pin 72 passes through the slide way 61 and is in sliding fit with the slide way 61.
