Description

Technical Field

[0001] The present invention specifically relates to the technical field of valves, and in particular to a mechanical valve capable of adjusting flow. Background Art

[0002] A valve is a control component in a fluid delivery system with functions such as cutoff, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion or overflow pressure relief.

[0003] A flow control valve is a valve that controls the flow of a throttle port by changing the size of the fluid resistance of the throttle port under a certain pressure difference, thereby adjusting the movement speed of the actuator (hydraulic cylinder or hydraulic motor). Traditional flow control valves have complex internal structures, with many structures and many parts in contact with water. They are prone to damage after long-term use. For this reason, we provide a mechanical valve with adjustable flow. When adjusting the flow, the flow is controlled by the size of the contact between the flow control rod and the flow control hole. The mechanical transmission parts inside will not come into contact with water, thereby ensuring its normal transmission. Secondly, the mechanical transmission valve has a longer life. Summary of the invention

[0004] The object of the present invention is to provide a mechanical valve capable of adjusting flow rate, so as to solve the problems mentioned in the background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A flow-adjustable mechanical valve comprises a water outlet pipe, wherein the water outlet pipe is cooperatively connected with a water inlet pipe and a flow control hole is provided on the water outlet pipe; the water outlet pipe is cooperatively connected with an outer shell, a flow rate control rod is provided inside the outer shell; a circular hole is provided on the water outlet pipe for facilitating the insertion of the flow rate control rod, and the water outlet pipe and the outer shell are cooperatively welded.

[0007] As a further technical solution of the present invention, a connecting seat is fixed to the outer side of the flow rate control rod by bolts, a guide seat is welded to the bottom of the connecting seat, and the guide seat is sleeved on the outer side of the guide rod.

[0008] As a further technical solution of the present invention, the flow rate control rod is configured in a conical shape at one end close to the water outlet pipe, and the other end is connected to the linkage pipe through a thread, the linkage pipe is connected to the large gear, and the large gear is connected to the seat bearing installed on the outer shell.

[0009] As a further technical solution of the present invention, the large gear is meshedly connected with the small gear, and the small gear is cooperatively connected with the seat bearing installed on the inner mounting frame.

[0010] As a further technical solution of the present invention, the pinion is cooperatively connected with a driving shaft of a driving motor, and the driving motor is fixed to the outer shell by bolts.

[0011] As a further technical solution of the present invention, both ends of the guide rod are fixed to the inner mounting frame by bolts, and the inner mounting frame is fixed to the inner wall of the outer shell by bolts.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. In the present invention, water flows in through the water inlet pipe and enters the water outlet pipe through the flow control hole. When controlling the flow, the flow rate control rod moves. One end of the flow rate control rod is tapered. The flow rate is controlled by the contact distance between the flow rate control rod and the flow control hole. When the flow rate control rod is closer to the flow control hole, the liquid resistance is greater, so the water flow is smaller. The farther away, the opposite is true. Only the flow rate control rod is in contact with the water flow, and the parts that control the movement of the flow rate control rod do not contact the water, so the service life is longer.

[0014] 2. In the present invention, the flow rate control rod is connected with the linkage pipe through a thread, and the flow rate control rod is sleeved on the outside of the guide rod through a guide seat. The large gear drives the linkage pipe to rotate, and the flow rate control rod moves along the guide rod;

[0015] 3. In the present invention, the large gear is meshed with the small gear, and the driving motor drives the connected small gear to rotate, thereby providing power for the movement of the flow rate control rod. Secondly, the small gear drives the large gear to rotate, which can achieve a deceleration effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] By adopting the above technical solution, water flows in through the water inlet pipe 1 and enters the water outlet pipe 3 through the flow control hole 2. When controlling the flow, the flow rate control rod 4 moves. One end of the flow rate control rod 4 is tapered. The flow rate is controlled by the contact distance between the flow rate control rod 4 and the flow control hole 2. The closer the flow rate control rod 4 is to the flow control hole 2, the greater the liquid resistance, and thus the water flow is small. The farther they are from the flow control hole 2, the opposite is true. Only the flow rate control rod 4 is in contact with the water flow, and the parts that control the movement of the flow rate control rod 4 do not come into contact with the water, thereby extending the service life.

[0024] In this embodiment, a connecting seat 5 is fixed to the outer side of the flow rate control rod 4 by bolts, a guide seat 7 is welded to the bottom of the connecting seat 5, and the guide seat 7 is sleeved on the outer side of the guide rod 8.

[0026] By adopting the above technical solution, the flow rate control rod 4 is connected to the linkage tube 6 through a thread, and the flow rate control rod 4 is sleeved on the outside of the guide rod 8 through the guide seat 7. The large gear 9 drives the linkage tube 6 to rotate, and the flow rate control rod 4 will move along the guide rod 8.

[0027] In this embodiment, the large gear 9 is meshedly connected with the small gear 10 , and the small gear 10 is cooperatively connected with a seat bearing installed on the inner mounting frame 11 .

[0028] Furthermore, the pinion 10 is cooperatively connected with the driving shaft of the driving motor 13, and the driving motor 13 is fixed to the outer shell 12 by bolts.

[0029] By adopting the above technical solution, the large gear 9 is meshed and connected with the small gear 10, and the driving motor 13 drives the connected small gear 10 to rotate, thereby providing power for the movement of the flow rate control rod 4. Secondly, the small gear 10 drives the large gear 9 to rotate, which can achieve a deceleration effect.

[0030] In this embodiment, both ends of the guide rod 8 are fixed to the inner mounting frame 11 by bolts, and the inner mounting frame 11 is fixed to the inner wall of the outer shell 12 by bolts.

[0031] By adopting the above technical solution, the inner mounting frame 11 can play a connecting and supporting role.

[0032] The working principle of the present invention is as follows: when in use, the large gear 9 is meshed with the small gear 10, and the driving motor 13 drives the connected small gear 10 to rotate, thereby providing power for the flow rate control rod 4 to move. Secondly, the small gear 10 drives the large gear 9 to rotate, which can play a deceleration effect; the flow rate control rod 4 is connected with the linkage pipe 6 through a thread, and the flow rate control rod 4 is sleeved on the outside of the guide rod 8 through the guide seat 7.

When controlling the flow rate, the flow rate control rod 4 moves, and one end of the flow rate control rod 4 is conical. The flow rate is controlled by the contact distance between the flow rate control rod 4 and the flow control hole 2. When the flow rate control rod 4 is in contact with the flow control hole 2, the liquid resistance is greater, so that the water flow is small, and the farther the flow rate control rod 4 is, the opposite is true; only the flow rate control rod 4 is in contact with the water flow, and the parts that control the movement of the flow rate control rod 4 do not contact with the water, so that the service life is longer.
