Abstract

The utility model relates to a micro adjustable flow switch that adopts a new design. The utility model consists of a short flow direction lever, a bottom shell, a spring positioning support, a spring, a pinchcock, a microswitch, a top cover, a pad, a switch support assembly, a main lever, a flow adjusting bolt, a corrugated pipe, a tie-in assembly, and a flow direction chip. The utility model has the advantages that the bulk is reduced 1/3 compared with the original flow switch, the repeatability error is smaller than 2.5%, and the maximum working pressure reaches 24Kg. The utility model reduces raw material consumption and avoids leakage and erosion, which can be widely applied to industries of domestic central air conditioner, water supply equipment, air conditioning, etc.

Description

Miniature adjustable flow switch

Technical field:

The utility model relates to a kind of miniature adjustable flow switch that is used in the industries such as residential central air conditioning, supply equipment, air conditioning, belongs to the flow switch technical field.

Background technology:

The volume of the flow switch of producing both at home and abroad is all bigger at present, flow switch can't be installed to the inside of system equipment, thereby be subjected to rust corrosion easily, the friction of the inner transmission mechanism of flow switch reduces than its sensitivity of ambassador, and make the repeatable accuracy error more greatly more than 3%, operating pressure only in 10kg, seepage easily.

Summary of the invention:

The purpose of this utility model invents exactly that a kind of volume is little, the repeatable accuracy error is little, operating pressure is up to 24kg, non-leakage, incorrosive miniature adjustable flow switch, can be applied to industries such as residential central air conditioning, supply equipment, air conditioning widely.

For realizing above purpose, the technical solution of the utility model is to adopt brand-new design, a kind of brand-new miniature adjustable flow switch is provided, it is by the short lever that flows to, drain pan, the spring locating rack, spring, spring clip, miniature sensitive switch, loam cake, cushion block, the switch bracket assembly, main lever, regulate flow screw, bellows, adapter assembly, flow direction plate is formed, flow direction plate is fixed on short the flow direction on the lever, the two ends of bellows flow to lever with weak point respectively and adapter assembly is welded to connect, adapter assembly is enclosed within on the drain pan and connects with screw, spring housing is being regulated on the flow screw, two ends are all fixed by main lever and spring locating rack, regulating flow screw is clamped by spring clip, play the screw loosening effect that prevents, pad has been gone up the cushion block of insulating effect above the switch bracket assembly, be equipped with miniature sensitive switch on the cushion block, and be screwed on the switch bracket assembly, loam cake and drain pan are closed to be screwed.

The utility model has the advantages that the employing brand-new design, volume is compared with existing flow switch dwindled 1/3 that the repeatable accuracy error is less than 2.5%, raw materials consumption is few, non-leakage, do not corrode, and operating pressure is up to 24kg.

Description of drawings:

Fig. 1 is miniature adjustable flow switch structure chart.

Embodiment:

As shown in Figure 1, miniature adjustable flow switch is by the short lever 1 that flows to, drain pan 2, spring locating rack 3, spring 4, spring clip 5, miniature sensitive switch 6, loam cake 7, cushion block 8, switch bracket assembly 9, main lever 10, regulate flow screw 11, bellows 12, adapter assembly 13, flow direction plate 14 is formed, flow direction plate 14 is fixed on short the flow direction on the lever 1, the two ends of bellows 12 flow to lever 1 with weak point respectively and adapter assembly 9 is welded to connect, adapter assembly 13 is enclosed within on the drain pan 2 and connects with screw, spring 4 is enclosed within to be regulated on the flow screw 11, two ends are all fixing by main lever 10 and spring locating rack 3, regulating flow screw 11 is clamped by spring clip 5, play the screw loosening effect that prevents, pad has been gone up the cushion block 8 of insulating effect above the switch bracket assembly 9, be equipped with miniature sensitive switch 6 on the cushion block 8, and be screwed on switch bracket assembly 9, loam cake 7 and drain pan 2 are closed to be screwed.Loam cake 7 sides have aperture and load onto the India-rubber wire circle.

The loam cake 7 of miniature adjustable flow switch and drain pan 2 usefulness P.C engineering plastic materials are made, it can improve heat insulating ability, again can antirust Wear-resistant, high-temperature resistant, other all parts are stainless steel material and make, and guarantee that miniature adjustable flow switch in any environment can operate as normal.

Before miniature adjustable flow switch is installed, regulate flow screw 11 earlier, be adjusted to and meet the required flow of product, then miniature adjustable flow switch is installed in the threeway of water pipe, flow direction plate 14 is put in the water of water pipe, when flow increases, flow direction plate 14 is subjected to the impulse force of water, and the drive weak point flows to lever 1 and moves, and has promptly driven main lever 10 actions, and passed to miniature sensitive switch 6, make miniature sensitive switch 6 send the Signal Regulation flow automatically to normal level.
