Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model water supply connector;
Fig. 2 is the three-dimensional exploded view of the utility model water supply connector.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Refer to Fig. 1, Fig. 2, the utility model provides the water supply connector on a kind of constant-temperature water faucet 1, be installed on water inlet of hot water on constant-temperature water faucet 1 and cold water inlet, water supply connector is also provided with seal ring 21, comprise housing 1, described housing 1 is provided with water intake 2 and water outlet 3, is distributed with backstop 4, crosses water device 5 and filter screen 6 in housing 1; Under the existence of backstop 4, in use, external water pipe is directly communicated with the water intake 2 of housing 1, and intake pressure can be made constant; Described backstop 4 is in water outlet 3, comprise spool 7, spring 8 and diaphragm 9, described spool 7 is located in the inner chamber of housing 1, described spool 7 comprises the body of rod 10 and support platform 11, spring 8 is set between inner chamber and support platform 11, the body of rod 10 withstands on water outlet 3, and is provided with diaphragm 9 between the body of rod 10 and water outlet 3; When water feeding pressure is greater than the elastic force of spring 8, diaphragm 9 leaves water outlet 3, and water intake 2 communicates with water outlet 3; When water feeding pressure is less than the elastic force of spring 8, diaphragm 9 mates at water outlet 3, and water outlet 3 is closed; Described filter screen 6 is located at water intake 2, arranges water device 5 between filter screen 6 and backstop 4.
Described water device 5 excessively comprises catch 12, the excessively hydrosphere 13 that the center of arranging up and down arranges through hole, between catch 12 and mistake hydrosphere 13, place O shape enclose 14, one bolt 15 through through hole and by nut 16 by catch 12, O shape circle 14 and cross hydrosphere 13 and be fixed as one, described catch 12 with cross hydrosphere 13 and be provided with multiple water hole.The bottom surface of described catch 12, the outer surface crossing the end face of hydrosphere 13, the inwall of housing 1 inner chamber and O shape circle 14 together form unhurried current space.
The water outlet 3 of described housing 1 is in outwardly open wide-angle, and what diaphragm 9 was fitted in wide-angle faces the wall and meditates on 18.
Described spool 7 comprises valve rod 10 and support platform 11, and described valve rod 10 comprises main body 19 and accessory body 20, and described main body 19 be the criss-crossing sheet of axis formation with center line with two panels support plate; Described accessory body 20 is cylindric, is provided with the groove 17 caved inward at the middle part of its outer wall, and described diaphragm 9 is arranged in groove 17; Support platform 11 is in the bottom of main body 19, is the extension laterally of two panels support plate end face.
When mounted, be set on the body of rod 10 of spool 7 by spring 8, and be plugged in housing 1, pressing spool 7 makes the body of rod 10 through water outlet 3 and is exposed to outside housing 1, is inserted in by diaphragm 9 in the groove 17 of the body of rod 10; Then, be assembled into one crossing water device 5, be provided with a step at the inwall of housing 1 inner chamber, the catch 12 crossing water device 5 is against on step, finally, loads filter screen 6.
Below working principle of the present utility model is described:
Current are flowed into by water intake 2, through filter screen 6, flow through hydrosphere 13 and enter joint 1 internal cavities with catch 12; Cross hydrosphere 13 to be filled can be done straight line motion along catch axle center (figure being labeled as bolt 15) by nut 16 and catch 12 casket, when hydraulic pressure increases, cross hydrosphere 13 to extrude O shape circle 14 and produce the water inlet that deformation reduce on catch 12, by reducing water inlet aperture, to limit current excessive; When hydraulic pressure reduces, cross hydrosphere 13 pairs of O shapes and enclose 14 pressure and diminish, O shape circle 14 produces less deformation or undeformed, and water inlet aperture increases reduces water inlet resistance, thus in different pressures situation constant inflow.
Current move up through joint inner chamber impact extrusion spool 7 interlock diaphragm 9, and water outlet 3 is opened, and water flows out.
Spring 8 is springs of a kind of stainless steel slight pressure, and during to ensure that water flow pressure is very little, water outlet 3 also can be opened.Simultaneously when water intake 2 does not have hydraulic pressure, when having small hydraulic pressure outside water outlet 3, water outside water outlet 3 can not blow back into hydraulic pressure outside water intake 2.(water outlet 3 larger time, water intake 2 is without hydraulic pressure or less hydraulic pressure, and diaphragm 9 can close water intake 3 under pressure is done).
Water supply connector on the constant-temperature water faucet provided the utility model embodiment is above described in detail, apply specific case herein to set forth principle of the present utility model and mode of execution, the explanation of above embodiment is just for helping to understand the technological scheme that the utility model discloses; Meanwhile, for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
