Abstract

The utility model relates to a cold and hot water mixed regulating control valve. A valve core is rotated to alter a relative position between a cold, a hot and a mixing water holes on a valve seat and a combined hole in the valve core for enabling the three holes to be totally communicated with each other, to be communicated two by two or to be totally not communicated with each other, and thereby, the purpose of using one valve to control a cold, a hot and a mixing water conduits can be achieved. The valve is especially suitable to be used for occasions using mixed cold and hot water for shower bath and washing.

Description

Hot and cold water mixing adjusting control valve

The utility model belongs to liquid distribution technique field, specifically a kind of hot and cold water mixing adjusting control valve.

At present, it generally is to carry out with two valves that the hot and cold water that shower is used is regulated mixing, and cold valves is transferred cold water, water valve is transferred hot water, is mixed into the warm water of using for bathing after the adjusting again, and its shortcoming is that two valves must be regulated respectively, the adjusting time is long, wastes water in the adjusting, and it is very not convenient to use.

The purpose of the present utility model is to overcome the deficiency of above technology and the novel hot and cold water mixing adjusting control valve that provides valve of a kind of need promptly can regulate cold water and hot water simultaneously and their are mixed.

The purpose of this utility model is achieved in that a kind of hot and cold water mixing adjusting control valve, comprise: have the valve seat (1) in A, B, three holes of C, the spool (2) that has D, E, three holes of F, handle (3), nut (4), packing ring (5), the central axis in A, the B that it is characterized in that being opened, C, D, E, six holes of F is on same cross section.Like this, when spool (2) rotates on valve seat (1), spool (2) is gone up the combined hole be made up of D, E, F three holes and the relative position between three paddle holes of A, B, C on the valve seat (1) is changed, and leads it: perhaps A, B, C three holes communicate or A, B, C three holes in two holes communicate and with another hole obstructed or A, B, C three holes not connected.When reality is used, hot and cold, mixed water conduit is inserted in A, B on the valve seat (1), C three holes respectively, rotational valve core (2), go up the relative position in A, B, C three holes to change spool (2) upper combined hole and valve seat (1), A, B, when C three holes communicate, be that hot and cold water is mixed into warm water, this moment adjustable orifice aperture, to regulate the ratio of hot and cold water, change the temperature of mixing water, A, B, when C three holes communicate in twos, then be single heat supply water, or single cooling water, A, B, when C three holes are not connected, cut off whole inlet and outlet pipe lines.

Adopt the utility model only need can realize that hot and cold water mixes, regulates, the purpose of control, save trouble, save time, convenient with a valve.

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

Fig. 1 is the utility model structure diagram

Fig. 2 is the K-K sectional drawing of Fig. 1

By accompanying drawing 1 as seen, valve seat (1) is a threeway that has A, B, C three holes, and its center has a taper axis hole that matches with spool (2).Spool (2) be one one little, the bearing pin of a big middle band tapering, the microcephaly is the screw thread spindle nose, by means of tightening of nut (4) spool (2) is fixed on the valve seat (1), and spool (2) can freely be rotated in the taper hole of valve seat (1), the effect of packing ring (5) is the axial clearance of sealed valve core (2).The major part of spool (2) stretches out outside the valve seat (1), and a handle (3) is housed, and people can make spool (2) rotation by pulling handle (3).By accompanying drawing 2 as seen, A on the valve seat (1), B, D on three holes of C and the spool (2), E, the combined hole that F three holes are formed is on same radial cross section, A, B, C three holes are connected on cold respectively, heat, on the pipeline of mixing water, D, E, one is straight hole in F three holes, two is inclined hole in addition, the relative position in these six holes has determined A, B, logical and obstructed between C three holes, communicate obstructed with the C hole for the A hole shown in Fig. 2 with B, if rotate counterclockwise spool (2), as seen following variation the: A takes place in their relative position, B, C all communicates, and the aperture between A and the combined hole from large to small, and the aperture between B and the combined hole is changed from small to big; Continue to be rotated counterclockwise spool (2), then the A hole is blocked, and only surplus B communicates with C; When spool (2) forwarded 100 °-150 ° to, this moment, A, B, C three holes were not connected, and all water routes are cut off.

Claims

A kind of hot and cold water mixing adjusting control valve, comprise: have the valve seat (1) in A, B, three holes of C, the spool (2) that has D, E, three holes of F, handle (3), nut (4), packing ring (5), the central axis in A, the B that it is characterized in that being opened, C, D, E, six holes of F is on same cross section.
