Detailed Description
Fig. 1 and 2 show structural diagrams of a flow controller. In the figure, the flow controller comprises a body 6 and a combination body, wherein the combination body comprises a lifting rod 2, an upper cover 3, an upper control body 4 and a lower control body 5. The lower end of the lifting rod 2 is provided with a disc 2a, the disc 2a is inserted into a long groove 4a on the upper control body 4, the upper control body 4 is arranged in the inner cavity of the upper cover 3 in a sliding mode, and the lower part of the upper control body 4 is provided with a lower cylinder 4b, an inverted V-shaped groove 4c for adjusting flow and a circular ring groove 4e. The lifting rod 2 fixedly connected with the disc 2a passes through the upper part of the upper cover 3, the lifting rod 2 is in threaded connection with the upper cover 3, the lower control body 5 is in threaded fixed connection with the lower end of the upper cover 3, and the small sealing conical surface 4d on the upper control body 4 and the large sealing conical surface 5a on the lower control body 5 form a sealing conical surface. The assembly is arranged in the body 6 and is fixedly connected with the internal thread on the body 6 by adopting the external thread on the upper cover 3. O-shaped ring seals are arranged between the upper cover 3 and the body 6, between the upper control body 4 and the upper cover 3 and between the lower control body 5 and the body 6. The top end of the lifting rod 2 is provided with a spanner 1 connected by a square hole. The lower cylinder 4b of the upper control body 4 is matched with an inner hole on the lower control body 5, and the circular ring groove 4e is matched with an upper end ring body of the lower control body 5. The upper part of the upper cover 3 is provided with a hexagonal boss 3a through which the lifting rod 2 passes.
Fig. 3 shows a state diagram of a flow controller when it is on. The lifting rod is rotated by the wrench 1, the lifting rod 2 drives the upper control body 4 to move upwards, the small sealing conical surface 4d on the upper control body 4 is separated from the large sealing conical surface 5a on the lower control body 5, when the tip part of the inverted V-shaped groove 4c is higher than the upper plane of the lower control body 5, the fluid in the fluid inlet cavity flows from the upper part to the lower part of the fluid outlet cavity through the inverted V-shaped groove 4c, the flow area is gradually increased along with the gradual upward movement of the inverted V-shaped groove 4c, and the fluid in the fluid inlet cavity gradually increases from the upper part to the lower part of the fluid outlet cavity through the inverted V-shaped groove 4c, so that the flow rate adjusting function is realized. When the bottom plane of the inverted V-shaped groove 4c is higher than the upper plane of the lower control body 5, the annular flow area formed between the two is larger than the through hole area of the lower control body 5, and the flow rate is not regulated any more.
