Abstract
The utility model relates to a sensor, in particular to a plastic valve body of a flow sensor. An inlet and an outlet are formed on the plastic valve body and the inlet and the outlet are communicated with each other; and weblike metal sleeve is arranged on the inner part of the wall of the valve body at the inlet and the outlet. The utility model further comprises a flow sensor which comprises the plastic valve body, a magnetic component and a hall sensor component, wherein, the plastic valve body adopts the structure; the magnetic component rotationally arranged in the plastic valve body and between the inlet and the outlet generates magnetic polarity change signals through rotation driven by flow; and the hall sensor component receives the magnetic polarity change signals sent by the magnetic component and converts the signals into electric pulse signals for output. The weblike metal sleeve is arranged on the inner part of the wall of the valve body at the inlet and the outlet in the plastic valve body, thereby greatly improving the self strength of the valve body, and solving the problem that the installation of the prior plastic valve body is easy to split.
Description
Technical field
The utility model relates to a kind of sensor, particularly relates to a kind of plastics valve body and water flow sensing unit of water flow sensing unit.
Background technology
Water flow sensing unit in the market mostly adopts copper to make valve body, and weight is big, the cost height.In order to address the above problem, the manufacturer who has uses PPS plastic production valve body, however PPS plastics insufficient strength, valve body when mounted, ftracture easily in its inlet or exit.
The utility model content
The problem that when technical problem to be solved in the utility model is the plastics valve body installation that solves water flow sensing unit ftracture easily in its inlet or exit.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted provides a kind of plastics valve body of water flow sensing unit, have an inlet and an outlet and described entrance and exit and be communicated with, the valve body wall inside at entrance and exit place is embedded with the net metal cover respectively.
In the such scheme, the material of plastics valve body is the PPS plastics.
The utility model also provides a kind of water flow sensing unit, comprise plastics valve body, magnet assembly and hall sensor component, described plastics valve body adopts said structure, described magnet assembly, rotation is arranged on described plastics valve inner and between entrance and exit, at the drive backspin of the current magnetisation change in polarity signal of changing the line of production; Described hall sensor component, the magnetic polarity variable signal that the reception magnet assembly sends also changes into electric impulse signal output.
The utility model because the valve body wall inside at plastics valve body entrance and exit place is embedded with the net metal cover respectively, has improved the intensity of valve body itself greatly, has solved former plastics valve body the problem of cracking easily is installed.
Description of drawings
Fig. 1 is the plastic valve body structure synoptic diagram of the utility model water flow sensing unit;
Fig. 2 is the structural representation (being unkitted hall sensor component) of the utility model water flow sensing unit;
Fig. 3 is the water flow sensing unit upward view among Fig. 2.
Embodiment
Below in conjunction with accompanying drawing the utility model is made detailed explanation.
As shown in Figure 1, the material of the plastics valve body 2 of the utility model water flow sensing unit is the PPS plastics, has an inlet M and an outlet N and described inlet M and outlet N and is communicated with, and the valve body wall inside at inlet M and outlet N place is embedded with net metal cover 1 and 3 respectively.
As Fig. 2, shown in Figure 3, the utility model also provides a kind of water flow sensing unit, comprise plastics valve body 12, magnet assembly 13 and hall sensor component 15, described plastics valve body 12 adopts said structure, have an inlet M and an outlet N and described inlet M and outlet N and be communicated with, the valve body wall inside at inlet M and outlet N place is embedded with net metal cover 11 and 14 respectively; Described magnet assembly 13, rotation are arranged on described plastics valve body 13 inside and are entering the mouth between M and the outlet N, at the drive magnetic assembly 13 rotation generation magnetic polarity variable signals of current; Described hall sensor component 15 is arranged on the outside surface of plastics valve body 12, and the magnetic polarity variable signal that the reception magnet assembly sends also changes into electric impulse signal from plug 16 outputs.
The utility model can be used on the water heater, and current drive magnet assembly and rotate, and produces magnetic polarity, and by hall sensor component the variable signal of magnetic polarity is changed into electric impulse signal and remove to control water heater to controller, thereby reaches the water heater anti-dry.When the water reverse direction flow is fashionable, magnet assembly can not rotate, and does not just produce any signal yet.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, all fall within the protection domain of the present utility model.
Claims (3)
