Description

Flow controller

Technical Field

The utility model belongs to the technical field of liquid flow control, and particularly relates to a flow controller.

Background

The liquid flow controller is a common device in various industries, in the petroleum industry, the flow controller in the dirty oil conveying pipeline is often blocked, after the flow controller is blocked, the blocking needs to be detached, the device is very troublesome, the workload is increased due to frequent detachment, and the leakage probability between the pipeline and the flow controller is increased due to frequent shackle.

Disclosure of Invention

In order to solve the problem that the flow controller on the dirty oil conveying pipeline is blocked and then the blocking is required to be detached, the utility model provides the flow controller which can be blocked on line and is very convenient.

The technical scheme provided by the utility model is as follows: the utility model provides a flow controller, includes shell body and the slip core that is located in the shell body, the shell body has import and export, is provided with the spring between one end of slip core and the shell body, and the slip core has the trend of shutoff with the import under the effect of spring, fixedly connected with keeps off the ring in the slip core, the spring set up between keeping off ring and shell body, the inboard slip seal of the slip core one end that is close to the import is provided with the shutoff board, still is provided with the threaded rod in the slip core, the one end and the shutoff board of threaded rod are connected, the axial displacement of threaded rod drives shutoff board synchronous movement, the middle part and the shutoff ring threaded connection of threaded rod, through rotatory threaded rod, change the position of shutoff board in the slip core; the side wall of the sliding core between the plugging plate and the baffle ring is provided with a plugging opening.

The further technical scheme is as follows: the other end of the threaded rod extends out of the outer shell.

The further technical scheme is as follows: the sliding core is matched with the outer shell through the stop pin, so that the sliding core is prevented from rotating relative to the outer shell.

The further technical scheme is as follows: the end face of the sliding core is provided with a limiting step for preventing the plugging plate from sliding off.

The further technical scheme is as follows: the inner wall of the sliding core at the baffle ring is provided with a step for limiting the baffle ring.

Compared with the prior art, the utility model has the beneficial effects that: according to the utility model, on-line blocking can be realized by changing the height position of the blocking plate, frequent disassembly of the flow controller is avoided, the disassembly workload is greatly reduced, and the leakage probability of the joint of the dirty oil pipeline and the flow controller is also reduced.

Drawings

Fig. 1 is a schematic structural view of the present utility model.

In the figure: 1. an outer housing; 2. a sliding core; 3. a stop pin; 4. a plugging plate; 5. an inlet; 6. an outlet; 7. plugging the opening; 8. a baffle ring; 9. a spring; 10. a threaded rod.

Detailed Description

In order to make the technical problems, technical schemes and beneficial effects to be solved more clear, the utility model is further described in detail below with reference to the accompanying drawings and embodiments.

As shown in fig. 1, the structure of the embodiment includes an outer casing 1 and a sliding core 2 located in the outer casing 1, the upper end of the sliding core 2 is in sliding sealing fit with the outer casing 1, the lower end of the outer casing 1 is an inlet 5, the side end is an outlet 6, a baffle ring 8 is fixedly connected in the sliding core 2, the baffle ring 8 and the sliding core 2 can be in interference fit or screw connection or are welded, a spring 9 is arranged between the baffle ring 8 and the outer casing 1, the sliding core 2 has a tendency of plugging the inlet 5 under the action of the spring 9, a plugging plate 4 is arranged on the inner side of one end of the sliding core 2 close to the inlet 5 in a sliding sealing manner, a threaded rod 10 is further arranged in the sliding core 2, one end of the threaded rod 10 is connected with the plugging plate 4, the axial movement of the threaded rod 10 drives the plugging plate 4 to move synchronously, the middle part of the threaded rod 10 is in threaded connection with the baffle ring 8, and the position of the plugging plate 4 in the sliding core 2 is changed by rotating the threaded rod 10; the side wall of the sliding core 2 between the plugging plate 4 and the baffle ring 8 is provided with a plugging opening 7, and after the plugging plate 4 moves upwards to cross the plugging opening 7, the inlet 5 and the outlet 6 are communicated through the plugging opening 7, so that online plugging can be realized.

The other end of the threaded rod 10 extends out of the outer shell 1, and the end part of the extending section is provided with a rotary handle, so that the threaded rod 10 can be conveniently rotated manually.

The sliding core 2 is matched with the outer shell 1 through the stop pin 3, so that the sliding core 2 is prevented from rotating relative to the outer shell 1.

The end face of the sliding core 2 is provided with a limit step for preventing the plugging plate 4 from sliding down.

The inner wall of the sliding core 2 at the baffle ring 8 is provided with a step for limiting the baffle ring 8.

To sum up, this application can realize on-line unblocking through the high position of change shutoff board 4, avoids frequent dismantlement flow controller, has reduced the dismantlement work load by a wide margin, has also reduced the probability that dirty oil pipeline and flow controller junction revealed.
