Abstract
The utility model relates to a water flow switch, comprising a valve seat and a valve body. The utility model is characterized in that the valve seat is provided with a water inlet channel and a water outlet channel, and the water inlet channel is communicated with the water outlet channel via a water opening. The valve body is rotatablely fixed on the valve seat, a piston which is arranged in the valve body and is provided with a magnet is butted on the water opening of the water inlet channel of the valve seat, a return spring is arranged between the valve body and the piston, and a dry reed pipe is arranged on the valve body. When water flows by, water pressure can eject the piston can drive the magnet to upwards move in line, and magnetic lines can trigger the dry reed pipe to move, on or off. Owing to the linear movement of the magnet, the utility model can trigger the dry reed pipe to act in a small range, and the utility model has the advantage of good sensitivity.
Description
The utility model relates to a kind of water flow switch.
Existing water flow switch is widely used on gas heater or the pipe pressurizing, and its primary structure is the hinge-type leaf door that is provided with a carry magnet in the chamber of valve seat, and Ye Men is enclosed in the porch of valve pocket, and has installed a tongue tube on valve seat.When current are flowed through the valve pocket porch, back down Ye Men, the magnet of Ye Menshang triggers the tongue tube action, and current flow out through an outlet of valve pocket.This water flow switch weak point is that the leaf door becomes the hinge-type design, and the magnet travel path of fixing on it becomes arcuation, often will make the tongue tube action need walk bigger stroke.
The purpose of this utility model is that designing a kind of is that magnet shift motion track is the water flow switch of linearity.
Task of the present utility model is achieved in that a kind of water flow switch of being made up of valve seat and valve body, it is characterized in that valve seat is provided with an inlet channel and a water outlet water channel, inlet channel is communicated with the water outlet water channel through the mouth of a river, valve body is rotated with on valve seat, the piston that is arranged in the valve body and has magnet contacts on the mouth of a river of valve seat inlet channel, valve body and piston space are provided with back-moving spring, have installed a tongue tube on the valve body.When flowing water is flowed through place, the inlet channel mouth of a river, hydraulic pressure backs down the piston that is enclosed on the mouth of a river, piston drives the magnet compression reseting spring and moves on the slideway of valve body is in line, be located at the outer tongue tube action of valve body this moment, control conducting or disconnecting two states, the motion because magnet is in line is so can trigger the tongue tube action in less stroke.
The utlity model has simple in structure, reasonable in design, the reliable characteristics that is active in one's movements, and offer convenience for maintenance or replacing parts.
Below in conjunction with concrete legend the utility model is described further:
Fig. 1 water flow switch profile
Fig. 2 is Figure 1A-A profile
Fig. 3 is Figure 1B-B profile
With reference to Fig. 1, Fig. 2 and Fig. 3, a kind of main body of water flow switch is made up of valve seat 1 and valve body 2 two parts, wherein on valve seat 1, be provided with an inlet channel 11 and a water outlet water channel 12, inlet channel 13 is communicated with water outlet water channel 12 through the mouth of a river, valve body 2 is rotated with on valve seat 1, the piston 3 that is arranged in the valve body 2 and has magnet 31 contacts on the mouth of a river 13 of valve seat 1 inlet channel, 3 in valve body 2 and piston are provided with back-moving spring 32, installed a tongue tube 21 on the valve body 2, when current are that tongue tube is subjected to the variation of magnetic force to produce state exchange by water flow switch, or be switched on or switched off, offer back level one switch controlling signal.3 one-tenth frustums of piston among the figure are inserted and are touched on valve seat 1 mouth of a river 13, and water sealing property is better, as long as there is weep can promote piston action.
Claims (2)
1, a kind of water flow switch of forming by valve seat and valve body, it is characterized in that valve seat is provided with an inlet channel and a water outlet water channel, inlet channel is communicated with the water outlet water channel through the mouth of a river, valve body is rotated with on valve seat, the piston that is arranged in the valve body and has magnet contacts on the mouth of a river of valve seat inlet channel, valve body and piston space are provided with back-moving spring, have installed a tongue tube on the valve body.
2, a kind of water flow switch according to claim 1 is characterized in that piston becomes frustum, inserts and touches on the valve seat mouth of a river.
