Description

Technical Field

[0001] The utility model belongs to the technical field of flow switches, and in particular relates to a baffle type flow switch. Background Art

[0002] The flapper flow switch is a type of mechanical flow switch. Most common flapper flow switches are target flow switches, and their working principle is as follows: when the fluid rushes towards the blade, the blade swings, changing the relative position of the magnet and the reed contactor, stimulating the contactor to close or open it. Once the fluid is interrupted, the blade returns to the starting position, stimulating the reed contactor again, and the mutual repulsion of the two magnets provides the force required to reset the flow switch, and the contactor returns to its previous state.

[0003] After searching CN 203721625U, a baffle type flow switch is disclosed. The baffle type flow switch includes a flow channel and a baffle. The baffle is connected to the upper part of the flow channel and rotates with the connection part of the baffle and the flow channel as the axis; a proximity switch is arranged outside the flow channel, and a trigger medium used as the proximity switch sensing element is installed on the baffle. In the initial state, when no fluid passes through the flow channel, the baffle is located at a position perpendicular to the axial direction of the flow channel. When fluid passes through the flow channel, the baffle can be pushed open only by overcoming the deadweight of the baffle, and the resistance is significantly reduced. After the fluid flow reaches a certain threshold, the trigger medium installed on the baffle will trigger the proximity switch and output the switch value. Compared with the baffle type flow switch in the prior art, the sensitivity is significantly improved. In addition, since the baffle type flow switch is a non-contact induction, the service life is improved.

[0004] However, the inventors have discovered that this technical solution still has at least the following defects:

[0005] According to the above-mentioned baffle type flow switch, when the baffle in the device is subjected to impact force, it will directly collide with the flow channel. Long-term impact will easily cause damage to the baffle.

[0006] In view of this, the present utility model is proposed. Summary of the invention
