CN2112734U - Regulating valve for hot and cold water - Google Patents

Abstract

The utility model discloses a regulating valve for hot and cold water, comprising a valve body, and a valve core which can rotate in the valve body. The recesses of the cold and the hot water and a water-supply recess are distributed on the periphery of the valve body. The regulating valve for hot and cold water is characterized in that the accesses of the cold and the hot water and a channel which is communicated with the accesses of cold and the hot water and the water-supply recess are arranged in the valve core, and the accesses of the cold and the hot water and the channel are respectively corresponding to the recesses of the cold and the hot water and the water-supply recess. The centers of the inlet ends of the accesses of the cold and the hot water are respectively over against the counter-clockwise directional side edge of the recess of the cold water and the clockwise directional side edge of the recess of the hot water. When the valve core of the regulating valve for hot and cold water is rotated by a single hand, the sectional areas of the cold and the hot water can be changed in inverse proportion to realize the regulation of water outlet temperature.

Description

Regulating valve for hot and cold water

The utility model relates to a kind of hot water or cold water's modulating valve.

At present, change hot water or cold water's water output in order to regulate supply water temperature, people normally are respectively equipped with cold water modulating valve and hot water modulating valve on left and right of "T"-shaped three-way union, and its shortcoming is: 1, cost height; Two modulating valve of user's turn simultaneously are obviously inconvenient when 2, regulating water temperature.

The purpose of this utility model is that a kind of hot water or cold water's modulating valve will be provided, when the spool of singlehanded this valve of turn of user can make variations that be inversely proportional to of hot water or cold water's area of passage, with the adjusting of realization water-exit temperature.

The utility model is to constitute like this, and it comprises valve body and the spool that can rotate in valve body.Be laid with hot water or cold water's port and water supply port on the perimembranous of valve body, the characteristics of its structure are to be provided with in the valve core respectively and hot water or cold water's port and the corresponding hot water or cold water's access of water supply port and the passage that is connected with hot water or cold water's access and water supply port, the center of cold water access entrance point faces the counter clockwise direction lateral margin of cold water port, and the center of hot water access entrance point faces the clockwise direction lateral margin of hot water port.

Below in conjunction with drawings and Examples the utility model is specifically described:

Fig. 1 is embodiment's one organigram, and Fig. 2 is the A-A sectional view of Fig. 1, and Fig. 3 is the B-B sectional view of Fig. 1.

Fig. 4 is embodiment's two organigrams, and Fig. 5 is the A-A sectional view of Fig. 4, and Fig. 6 is the B-B sectional view of Fig. 4.

Referring to embodiment one structure view Fig. 1, Fig. 2, Fig. 3,25 is the valve bodies with taper inner chamber among the figure; The 1st, the cold water port; The 2nd, the hot water port; The 3rd, the water supply port; The 4th, spool; The 5th, operating handle; The 6th, tighten up nut; The 7th, be placed in the pad with square through hole of spool bottom; The 8th, tighten up nut, its construction features are: this valve core is provided with respectively and corresponding hot water or cold water's access 9,10 of hot and cold water port and the water channel 13 that is connected with hot water or cold water's access and water supply port, and the center of hot water or cold water's access entrance point faces the counter clockwise direction lateral margin 11 of cold water port and the clockwise direction lateral margin 12 of hot water port respectively.This valve body top inner edge offers spool corner limited ring groove 14, and valve core top outer rim is provided with corresponding with it spacing short column 15.

When our dextrorotation movable valve plug, the cold water area of passage increases, and the hot water area of passage reduces, and the current temperature that the water supply port flows out reduces, and the spacing short column 15 on spool goes to an end of limited ring groove 14, and hot water or cold water's modulating valve cuts out.

Referring to 19 being valve bodies among Fig. 4, Fig. 5, Fig. 6 figure with hot water or cold water's port 22,23 and water supply port 24; The 20th, spool; The 16th, rubber pad, embodiment two is identical with embodiment one working principle, constructs similarly, and the main distinction is that the spool bottom is the spheroid 21 with hot water or cold water's access and water channel; Spool corner limited ring groove 17 is located on the thin bar on spool top; Corresponding with it spacing short column 18 is located on the valve body.

The utility model is novel, and compact structure is easy to use, and its market prospects are considerable.

Claims (1)

1, a kind of hot water or cold water's modulating valve comprises a valve body and the spool that can rotate in valve body, be laid with hot water or cold water's port and water supply port on the perimembranous of valve body, it is characterized in that: be provided with in the valve core respectively and hot water or cold water's port and the corresponding hot water or cold water's access of water supply port and the passage that is connected with hot water or cold water's access and water supply port, the center of cold water access entrance point faces the counter clockwise direction lateral margin of cold water port, and the center of hot water access entrance point faces the clockwise direction lateral margin of hot water port.
