Description

Electric water heater water tank four-way dual purpose valve

The utility model relates to a kind of electric water heater water tank four-way dual purpose valve, and it belongs to special valve.

The present inlet valve of electric water heater water tank, employing be safety check, its effect is only limited to water tank water intake, when the outlet pipe water temperature of water tank need be regulated, then will establish cold line and valve in addition, doing has so not only increased expense, and use also inconvenience, also influence aesthetic property.

The purpose of this utility model is to provide a kind of electric water heater water tank four-way dual purpose valve, and this valve promptly can be used for can regulating the water outlet water temperature to the radiator drain feeding cold water again, and having easy to use and reliable characteristics to water tank control water inlet.

In order to achieve the above object, the utility model is realized by following proposal.One section cylinder type valve body, its internal surface intermediate section is conical surface, the valve plug of configuration break-in, valve plug is furnished with valve rod, valve body front end and back end pipe section is shaped on female thread, the front end screw thread is equipped with friction top, the rear end screw thread is equipped with the cold water water supply connector, at valve body upper surface and a side surface and vertical tube of vertical connection and a horizontal pipe in same plane, they communicate with valve pocket by the valve pocket cinclides, and at place, horizontal pipe outer end, a two-way vertical tube intersects with it and connects, it is characterized in that: a. valve plug is that the big and front end in the little rear end of front end is the ring cone of opening, offer a through hole at awl on the wall, valve plug and valve rod stationary fit are stretched out valve and are trembled with fear and be shaped on screw thread on the valve rod of front end, and with one by planes such as 3～6 constitute etc. the polyhedron water-dredging head be connected the sealing head of the equipped rubber truncated cone body of water-dredging head front end; B. the inner chamber of water supply connector is the uniform circular flower chamber that is shaped on 3～6 little rectangles; C. equipped mixing head that becomes 30 °～45 ° hollow conehead to constitute with cone angle by hollow cylinder in horizontal pipe is offered a through hole below the conehead of mixing head; D. equipped inner chamber is big top and small bottom bell mouth shape hybrid nozzle in following vertical tube.

Fig. 1 is the utility model structural representation.Fig. 2 is the plan view of figure A-A section.Fig. 3 is a water supply connector inner chamber body generalized section.1 is valve plug among the figure, and 2 is valve body, and 3 is mixing head, and 4 is water output connector, and 5 is hybrid nozzle, 6 is the mixing head pilot hole, and 7 is the water tank water output connector, and 8 is the water tank water intake joint, and 9 is friction top, and 10 is valve rod, 11 is spring, and 12 is water-dredging head, and 13 is sealing head, and 14 is the cold water water supply connector.

Below in conjunction with accompanying drawing structure of the present utility model and the control water inlet of water tank thereof and the process of regulating tank water outlet water temperature are described.The utility model key problem in technology problem has two, and one is advancing and ending of ambient pressure water, and another is the current direction problem that enters behind the valve plug.Adopt following structure to solve to first technical problem the utility model: the valve rod front end is shaped on polyhedral water-dredging head such as screw thread and connection and is fitted in the sealing head of water-dredging head front end, because water-dredging head can not produce circumferential movement in the florid ornamentation in Chinese opera singing body, therefore when rotation valve rod, they can only do the action that moves forward and backward of front and back in intake pipe florid ornamentation in Chinese opera singing body.When clockwise rotating valve rod, they retreat, and sealing head leaves the water inlet, and cold water axially flows in the valve plug chamber by slit between water inlet and water-dredging head and the florid ornamentation in Chinese opera singing body.If rotate counterclockwise valve rod, water-dredging head and sealing head will advance, and then sealing head blocks the water inlet, stop into water.The cold water that enters the valve plug inner chamber flows to by following structure realizes control: valve rod is connected with stationary fit with valve plug, and they are carried out synchronously and rotate, and therefore can realize the transposition of valve plug cinclides by rotation valve rod, makes it and valve pocket cinclides centering.When rotation valve rod made valve plug cinclides and vertical tube center, then cold water flowed to water tank; When rotation valve rod during by valve plug cinclides centering horizontal pipe center, then cold water will flow to mixing head and mix with hot water.Therefore, the utility model just can be realized the flow direction with fluid stopping and control flows inlet valve body inner cold water of flowing to of cold water having reached the dual-purpose purpose of a valve by the position of rotation valve rod.Realization clockwise rotates 2～3 circles with valve rod when cistern water supply, and then the center of plug holes position centering being gone up vertical tube, cold water just can pass through the water inlet, and inner chamber, valve plug inner chamber are taken in water inlet, by valve plug cinclides and valve pocket cinclides, flow into vertical nozzle, enter water tank at last.Water tank water intake finishes, and rotation valve rod makes centering horizontal pipe center, valve plug cinclides position, and then cold water passes through mixing head, flows out and is flowed out by hybrid nozzle simultaneously from the dirty hot water of radiator drain from conehead below aperture, and the water supply that becomes thermophilic is just used.

The processing and manufacturing of parts of the present utility model is for the people with general machining knowledge To realize easily. Because this valve has with one when two effect, so production cost is low, and have and make With characteristics convenient, reliable, that neat appearance is installed.
