Abstract
The utility model provides a dual-purpose temperature regulator for a water heater. The utility model has the main structure that an inner cavity on the lower part of each of two through type valve seats is divided into a front mixing cavity and a back hot water inlet pipe cavity, and the upper part of each valve seat corresponding to the outer margin points of both side walls of the hot water inlet pipe cavity is separately provided with a cold water inlet hole and a cold water outlet hole; the upper part of each valve seat corresponding to the back both sides of the front mixing cavity is separately provided with a cold water through hole and a cold water diffluence hole, and the lower surface of a valve core sealed and positioned by a valve cap is provided with a circular arc-shaped communicating trough. The utility model has the advantages of simple structure, easy processing and fabrication, more convenient and flexible installation and regulation, no water leakage phenomenon in using process, etc.
Description
The utility model relates to a kind of liquid flow-conditioning, the dual-purpose temperature regulating switch of especially a kind of water heater.
Gas water-heater commonly used at present is mostly by regulating the gas flame size and regulating the cold water flow size that enters water heater and control the hot water temperature of flowing out water heater.This method for regulating temperature needs the inside and outside cooperation in bathroom to finish, and seems very inconvenient.Chinese patent CN2227771Y has proposed a kind of " the special-purpose temperature regulating switch of water heater ", its main structure characteristics are the regulating tanks that have degree of depth gradual change on the spool circumference of hollow cylinder is faced the wall and meditated, near the deep trouth end, offer long-round-shape and divide opening, spool hollow space and cap hollow space are respectively shunting chamber and mixing chamber, and are interconnected.Be provided with cold water inlet/outlet and hot water inlet/outlet at housing and cap hollow space, it utilizes the regulating tank present position of degree of depth gradual change to regulate water temperature by rotating the hollow cylinder spool.The temperature regulating switch of this structure is offered regulating tank on facing the wall and meditating at the circumference of cylindrical spool, utilize circumference to face the wall and meditate fully and dam, and its manufacturing is trouble, also is easy to generate water leakage phenomenon in the using process, influences using effect to a certain extent.
The purpose of this utility model just is to overcome above-mentioned deficiency of the prior art, and it is more simple to propose a kind of structure, and manufacturing is easy, installs and regulate easy, flexible, can not produce the water heater Temp.-controlled water valve of water leakage phenomenon in the using process.
The purpose of this utility model can following technological scheme realize, mixing chamber and back hot water inlet tube chamber before in two pasted valve type seat lower lumen, being separated out, valve seat top offers respectively corresponding to place, this hot water inlet tube chamber both sides of the edge that cold water enters the hole and cold water portals, offer cold water through hole and tap hole respectively corresponding to both sides, preceding mixing chamber rear portion, the spool lower surface of being located by valve bonnet seal offers the circular arc connectivity slot.Described circular arc connectivity slot cornerite is good with 132 °, described cold water advance hole and cold water go out the centerline hole angle be 60 ° for good, cold water enters the hole and cold water through hole center line angle the best is 90 °, cold water portals and tap hole center line angle is preferably 38 °.
Accompanying drawing 1 is vertical cross-sectional configuration schematic representation of the present utility model.
Accompanying drawing 2 is the A-A face sectional view in the utility model accompanying drawing 1.
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail: both sides have cold water interface into 1 and go out be separated out in the two pasted valve type seat lower lumen of cold water interface 2 before mixing chamber 3 and back hot water inlet tube chamber 4.
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail: have cold water interface into 1 in both sides and go out before being separated out in the two pasted valve type seat lower lumen of cold water interface 2 that to offer the center line angle respectively corresponding to outer rim place, hot water inlet tube chamber 4 two side be that 60 ° cold water enters hole 5 and cold water portals 6 mixing chamber 3 and back hot water inlet tube chamber 4, valve seat top, corresponding to both sides, preceding mixing chamber 3 rear portion offer respectively with the cold water 6 center line angles that portal be 38 ° cold water tap hole 7 and to advance hole 5 center line angles with cold water be 90 ° cold water through hole 8.It is 132 ° circular arc connectivity slot 10 that the lower surface that is positioned over the spool 9 on valve seat top has the radian cornerite, and described spool 9 is by valve gap 11 sealing location, and rotates by handle shaft 12.When using the utility model product, advancing cold water interface 1 joins with running water pipe, go out cold water interface 2 and be connected on the gas water-heater water intake, the hot water that flows out from gas water-heater outlet through pipeline enters after the hot water inlet tube chamber 4, and by preceding mixing chamber 3 from its outlet outflow.In the process of regulating water temperature, when handle shaft 12 clockwise rotates, when described circular arc connectivity slot 10 covered cold water simultaneously and advances hole 5 and cold water through hole 8, the cold water of inflow advanced in the preceding mixing chamber 3 that hole 5, connectivity slot 10 and cold water through hole 8 directly enter the bottom through cold water, and what flowed out this moment is cold water; Handle shaft 12 is rotated counterclockwise, described circular arc connectivity slot 10 covers simultaneously that cold water enters hole 5 and cold water portalled at 6 o'clock, the cold water that flows into portals through cooling water inlet 5 connectivity slots 10 and cold water and 6 enters the going out in the cold water interface 2 of bottom, entered in the preceding mixing chamber 3 by hot water inlet tube chamber 4 after delivering to the gas water-heater heating, what flowed out this moment is hot water again; When continuing to rotate counterclockwise handle shaft 12, described circular arc connectivity slot 10 covers cold water simultaneously and enters hole 5, cold water and portal 6 and during tap hole 7, the cold water that flows into is shunted from connectivity slot 10, most of cold water enters the gas water-heater heating, flows out from outlet after mixing chamber 3 hot water interior and wherein mixed before fraction directly entered by tap hole 7.Along with covering cold water, connectivity slot 10 portals 6 and the change of tap hole 7 areas, but the just water temperature that flows out of regulated at will.The utility model has simple in structurely compared with prior art, and manufacturing is easy, installs and regulate easy, flexible, can not produce characteristics such as water leakage phenomenon in the using process, especially is fit to the present supporting use of various gas water-heaters.
