Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
A kind of as shown in Figure 1 and Figure 2 electric water heater constant temperature weighing apparatus pressure-controlled device comprises housing 1, have the hot water inlet 10, hot water outlet 2, cooling water inlet 3 of connection on the housing 1, comprise valve body 9, constant temperature constant pressure valve core 8, valve core housing 95, valve pocket 12, valve plug 81, inner core 16, temperature transducer 15 and water-water jet 13 with housing 1 one to cooling water outlet 11, one constant temperature constant pressure valves of water heater; Constant temperature constant pressure valve core 8 is installed on the valve body 9 by valve core housing, constant temperature constant pressure valve core 8, valve core housing 95 can relatively rotate and liquid sealing, valve plug 81 and constant temperature constant pressure valve core 8 interference fit, valve pocket 12 is installed between valve plug 81 and the temperature transducer 15, the upper end of inner core 16 cooperates with valve plug 81, its lower end and temperature transducer 15, and water-water jet 13 is enclosed within on the temperature transducer 15 and be resisted against on the convex shoulder of temperature transducer 15, one Returnning spring 14 is arranged between the bottom of water-water jet 13 and valve body 9, a seal ring 131 is arranged on the water-water jet 13; One O-ring seal 121 and the sealing of valve body 9 intracavity liquids are arranged on the valve pocket 12, and valve body 9 communicates with the hot and cold water cavity 92,91 of housing, and valve body 9 is connected by mixed water channel 94 with flow valve body 52; Blind hole, lower end that inner core 16 upper ends are positioned at valve plug 81 cooperate with temperature transducer 15, and the two ends of inner core 16 respectively are provided with a bulge loop 161; Flow handwheel 5 connects with flow spool 6, and the flow handwheel 5 of flow spool 6 is provided with flow indication circle 51.
