Abstract
The utility model relates to an anti-scald safety valve which comprises a valve body, a base, a fixed valve plate, a moving valve plate and a valve rod, wherein the base is arranged at an opening at the bottom end of the valve body, and a cold water inlet, a hot water inlet and a water outlet are formed on the base; the fixed valve plate, the moving valve plate and the valve rod are arranged in the valve body from bottom to top, the upper part of the valve rod extends out of the upper end of the valve body and the lower part of the valve rod is in drivable fit with the moving valve plate; and the anti-scald safety valve is characterized in that a limiting mechanism for limiting the valve rod to rotate within a certain range is arranged between the valve rod and the inner wall of the valve body. The beneficial effects of the anti-scald safety valve are that due to the arrangement of the limiting mechanism in the valve core, and the limitation on the range of the valve rod and the valve plate, the control process corresponding to the rotation range of the valve rod can be as follows: closing-cold water-mixed water-hot water or hot water-mixed water-cold water-closing by pre-setting in advance. Therefore, when the anti-scald safety valve is opened for water supply, the cold water and the mixed water are firstly supplied, and then the hot water is supplied, thereby realizing anti-scald property and improving the safety.
Description
Technical field
The utility model relates to hot-water heating device technical field.
Background technique
In some easy water supply spools, heat responsive element and temperature control assembly are not set, just the operation of valve rod is controlled the ratio of hot and cold water inlet by the user.For example, No. 200520082444.0 utility model patents of China disclose a kind of novel water filling water-mixing valve core, this spool comprises moving valve plate and fixed valve plate, offer cold water hole, hot water hole and mixing water hole on the fixed valve plate, moving valve plate is provided with and can and mixes the water control hole that the water hole cooperates with fixed valve plate cold water hole, hot water hole.
Yet, lack anti-ironing mechanism in the above-mentioned easy water supply spool, do not know the spool principle and control under the situation of rule user (especially children), very likely reached the hot water end once supplying water, scald easily, there is potential safety hazard.
Summary of the invention
The purpose of this utility model is that limting mechanism is set in spool, the process that makes the user open water supply is: close → cold water → mixing water → hot water, the process of closing water supply is: hot water → mixing water → cold water → close, avoiding a water supply is exactly hot water, reaches the anti-scald purpose of safety.
Above-mentioned purpose is realized by following technological scheme: a kind of scalding preventing protection valve comprises: valve body, base, fixed valve plate, moving valve plate and valve rod; Base is arranged on valve body bottom end opening place, offers cold water intake, hot water intake and water outlet on it; Fixed valve plate, moving valve plate and valve rod are arranged in the valve body from bottom to up, and the valve body upper end is stretched out on the top of valve rod, and the bottom can cooperate drivingly with moving valve plate; It is characterized in that: be provided with the limting mechanism that the restriction valve rod rotates within the specific limits between valve rod and valve interior wall.
Described limting mechanism is the projection that the curve bath offered on the valve rod and valve interior wall are provided with, and projection embeds in the curve bath.
The beneficial effects of the utility model are: by limting mechanism is set in spool, the scope of restriction valve rod and fixed valve plate, by preestablishing, can so that the control procedure of the slewing area correspondence of valve rod be: close → cold water → mixing water → hot water, perhaps be: hot water → mixing water → cold water → close.Therefore, the utility model is when opening water supply, and inevitable cold water outlet of experience earlier and mixing water outlet are only hot water outlet at last, and be anti-scald, improved Security.
