Abstract
The utility model discloses a plumbing current limiting device which is mounted in an inner cavity of bathroom equipment. The plumbing current limiting device comprises an outer cover and a movable sheet. The outer cover is in a barrel shape, a hollow cavity is disposed inside the outer cover, and a water outlet hole is disposed at the bottom end of the outer cover. The movable sheet is arranged in the hollow cavity of the outer cover, and the external outline of the movable sheet is matched with the hollow cavity of the outer cover in corresponding mode. The middle of the movable sheet is provided with a water inlet hole which is matched with the water outlet hole to form a flow passageway, and the bottom of the movable sheet is provided with a protruding part which is used for adjusting a gap between the outer cover and the movable sheet by means of temperature sensing and deformation. The movable sheet is made of ethylene propylene diene monomer (EDPM) material. The plumbing current limiting device has the advantages of being automatic in flow adjustment, simple in structure, easy to produce, low in cost, small in size, long in service life and the like.
Description
Technical field
The utility model relates to the bathroom technical field, relates in particular to a kind of medium current-limiting apparatus that is applied in the hot-water heating equipment.
Background technique
The medium current-limiting apparatus of traditional water heating equipment is divided into mechanical type current-limiting apparatus and electronic type current-limiting apparatus.The mechanical type current-limiting apparatus is main with stage clip mechanism, and its preparation process is many and complicated, and required accessory is many, and manufacturing efficiency is low, and volume is big, and cost of production is high, makes tap or gondola water faucet moulding limited.It is main that the electronic type current-limiting apparatus adopts the electronic closed loop technology, and it must be controlled through electric power resource, complex process, and cost is high, and technical difficulty is bigger, and volume is big, restriction tap or gondola water faucet moulding.
The model utility content
The purpose of the utility model is the deficiency to existing technology, and a kind of hot-water heating current-limiting apparatus is provided, and has automatic adjusting flow, and is simple in structure, is prone to produce, and cost is low, and volume is little, advantages such as long service life.
In order to achieve the above object, the utility model adopts following technological scheme:
A kind of hot-water heating current-limiting apparatus is installed in the sanitary bath equipment inner chamber, and it comprises:
One enclosing cover, it is tubbiness, and its inside is provided with a cavity and the bottom is provided with an osculum;
One movable plate, it is located in the enclosing cover cavity and exterior contour is corresponding with the enclosing cover cavity cooperates, and the center is provided with and cooperates the water inlet that forms circulation road, bottom to be provided with one to regulate the jut in gap between enclosing cover and the movable plate with osculum through temperature distortion;
The movable plate of said movable plate for processing by the EDPM material.
Said movable plate is provided with at least one water inlet.
Said movable plate is provided with at least one jut, and said jut is taper.
Said enclosing cover upper end is provided with defining flange.
A kind of hot-water heating current-limiting apparatus of the utility model is fit in other water heating products such as water tap, gondola water faucet, and water gets into after the osculum of enclosing cover compiles outflow from the water inlet of movable plate.When the constant water temperature of hydraulic pressure raise, movable plate expanded, under the reaction extruding of enclosing cover; The aperture of movable plate water inlet diminishes, and the deliquescing of movable plate absorption heat, and jut is squeezed under the effect of pressure; Gap smaller between movable plate and the enclosing cover reaches the effect of automatic minimizing flow.When the constant water temperature of hydraulic pressure reduces; Movable plate is absorbed the part heat and shrinks, and the reaction force of enclosing cover diminishes, and the suffered extruding force of movable plate diminishes; The aperture change of movable plate water inlet is in greatly and returns to form; It is big that gap between movable plate and the enclosing cover becomes, and owing to the gap smaller that makes after the jut cooling hardening between movable plate and the enclosing cover, reach the effect of automatic increase flow.
A kind of hot-water heating current-limiting apparatus of the utility model volume is less, and it makes hot-water heating device modelings such as water tap or gondola water faucet unfettered.
The utility model has automatic adjusting flow through adopting said structure, and is simple in structure, is prone to produce, and cost is low, and volume is little, advantages such as long service life.

Embodiment
To shown in Figure 5, a kind of hot-water heating current-limiting apparatus of the utility model is installed in the sanitary bath equipment inner chamber like accompanying drawing 1, and it comprises:
One enclosing cover 1, it is tubbiness, and its inside is provided with a cavity 10 and the bottom is provided with an osculum 11;
One movable plate 2; It is located in the enclosing cover cavity 10 and exterior contour and 10 corresponding cooperations of enclosing cover cavity; The center is provided with and cooperates the water inlet 22 that forms circulation road, bottom to be provided with one to regulate the jut 21 in gap between enclosing cover 1 and the movable plate with osculum 11 through temperature distortion;
The movable plate of said movable plate 2 for processing by the EDPM material.
Said movable plate 2 is provided with at least one water inlet 22.
Said movable plate 2 is provided with at least one jut 21, and said jut 21 is taper.
Said enclosing cover 1 upper end is provided with defining flange 12.
A kind of hot-water heating current-limiting apparatus of the utility model is fit in other water heating products such as water tap, gondola water faucet, and water gets into after the osculum 11 of enclosing cover 1 compiles outflow from the water inlet 22 of movable plate 2.When the constant water temperature of hydraulic pressure raises; Movable plate 2 expands, and under the reaction extruding of enclosing cover 1, the aperture of movable plate water inlet 22 diminishes; And movable plate 2 absorbs the heat deliquescing; Jut 21 is squeezed under the effect of pressure, and the gap smaller between movable plate 2 and the enclosing cover 1 reaches the effect of automatic minimizing flow.When the constant water temperature of hydraulic pressure reduces; Movable plate 2 is absorbed the part heat and shrinks, and the reaction force of enclosing cover 1 diminishes, and movable plate 2 suffered extruding forces diminish; The aperture change of movable plate water inlet 22 is in greatly and returns to form; It is big that gap between movable plate 2 and the enclosing cover 1 becomes, and owing to the gap smaller that makes after the jut 21 cooling hardening between movable plate 2 and the enclosing cover 1, reach the effect of automatic increase flow.
A kind of hot-water heating current-limiting apparatus of the utility model volume is less, and it makes hot-water heating device modelings such as water tap or gondola water faucet unfettered.
The utility model has automatic adjusting flow through adopting said structure, and is simple in structure, is prone to produce, and cost is low, and volume is little, advantages such as long service life.
Above-mentioned listed concrete implementation is nonrestrictive, and concerning the personnel of present technique field, in not departing from the utility model scope, various improvement and the variation carried out all belong to the scope that the utility model is protected.
