Abstract

The utility model provides a single-handle mixing valve used for mixing cold and hot water, comprising a valve body, a valve core and a handle. The same cross-section on the middle lower part of the valve body is provided with two coaxial water inlet pipe connecting pieces and a water outlet connecting piece whose axial direction is vertical to the axial line of the water inlet pipe connecting pieces. The water inlet pipe connecting pieces are respectively thread fixed and connected with two L-shaped long and short water inlet connecting pipes, so as to cause the valve body to be connected firmly with the long and short water inlet connecting pipes. The water outlet connecting piece and the water inlet connecting pipe adopt a rubber sealing gasket for seal. The utility model has firm connection, high pressure bearing and high safety.

Description

Single handle mixing valve

The utility model belongs to the water valve that a kind of mixing hot and cold water is used, and is particularly suitable for using in order to regulate in the water temperature at electric water heater.

Placement between existing cold and hot Mixed water valve valve body and water inlet are taken over, what adopt is by only being connected with common plain seal pad between two intake pipe fittings on the valve body and the water inlet adapter and sealing, thereby be difficult to bear excess pressure, too high or install not at that time when hydraulic pressure, very easily cause adapter to come off, and have an accident.

The purpose of this utility model provides a kind of can making between valve body and the water inlet adapter and is connected the solid and reliable Mixed water valve of sealing.

The utility model includes valve body, spool is housed in the valve body, spool top is equipped with and is pressed the core nut, handle is equipped with on the spool top, two intake pipe fittings and an outlet pipe fitting are housed respectively on the same cross section in valve body middle and lower part, two intake pipe fittings are taken over two L shaped length water inlets respectively and are connected, it is characterized in that two intake pipe fittings are coaxial, the threaded end that water inlet is taken over is threaded with the nut seat that has nut, nut is threaded with the intake pipe fitting again, firmly be connected thereby valve body is taken over the length water inlet, between nut seat and intake pipe fitting, sealing gasket be housed.

Below in conjunction with description of drawings embodiment of the present utility model.

Fig. 1 is a whole longitudinal sectional view of the present utility model;

Fig. 2 is the A-A sectional view among Fig. 1.

Present embodiment has valve body (12), spool (20) is housed in the valve body (12), spool (20) top is equipped with and is pressed core nut (19), press core nut (19) upper end that rosette (18) is housed, screw (16) is equipped with on spool (20) top, compression spring (17) is housed on the screw (16), screw (16) handle (13) is contained on the spool (20) simultaneously, handle (13) is gone up by seal ring (14) trade mark lid (15) is housed, on the same cross section in valve body (12) middle and lower part two warm-cold inleting pipe fittings (4) are housed respectively, an outlet pipe fitting (10), two intake pipe fittings (4) are coaxial, the axis normal of the axis of outlet pipe fitting (10) and warm-cold inleting pipe fitting (4), seal ring (11) is housed on the outlet pipe fitting (10), warm-cold inleting pipe fitting (4) is fixedlyed connected with nut (6) screw thread respectively, (3) are taken in water inlet, (9) threaded end is equipped with nut seat (8), nut seat (8) is taken over (3) to water inlet, (9) firmly link together with screw thread with nut (6), adorn sealing gasket (7) between intake pipe fitting (4) and the nut seat (8), small sealing ring (5) is housed on intake pipe fitting (4), and (3) are taken in water inlet, (9) no threaded end is equipped with pad (2) and nut (1).Raise the water handle during use, be threaded to the hot water end, tap water enters electric water heater through valve body (12) and water inlet adapter (3), and hot water rises in electric water heater when tap water enters automatically, take over (9) from water inlet and enter valve body (12), flow out from water outlet, user's rotatable handgrip (13) can use after being transferred to suitable water temperature, depresses handle (13) again, spool (20) is closed, current no longer rise in the water inlet adapter (3), and the exchange of electric water heater hot and cold water promptly stops the anhydrous outflow of water outlet.
