Abstract
The utility model relates to an improved water faucet structure, including a valve seat with a cold water inlet hole and a water outlet A, which is characterized in that the valve seat is composed of a cold water outlet hole B communicated with the water outlet, a cold water outlet hole C communicated with an infall of a water heater, and a hot water inlet hole D communicated with the water outlet and connected with the water heater; in addition, a control valve core, which can change the water flow of the cold water outlet hole B and the cold water outlet hole C, is also arranged in the valve seat. Thanks to the issue of the instability of water pressure in the course of heating is resolved by the utility model, therefore a pressure relief valve and a cut-off valve are not be arranged additionally, so a dual purpose to increase safety and save manufacturing cost can be arrived at finally by the invention, and thus has a certain value of popularization and application.
Description
Technical field
The utility model relates to a kind of improved structure of tap, refers to linkage structure between inside aperture design of improvement water tap and the water heater especially, and is characteristic so that water heater obtains the stability and safety state with reducing cost.
Background technique
The bottom end face of general water tap is provided with three cavities, be respectively cold water inlet hole, hot water inlet hole and osculum, wherein the hot water inlet hole is connected with water heater with aqueduct, because the inlet valve of water heater is a closed state, when input cold water, water in the water heater can produce because of being heated and expand, when expansion is uncontrollable, water heater is damaged, when therefore water heater is connected with traditional water tap, need to install Decompression valves and check valve in the water heater, so not only Security is low but also manufacture cost is higher.Therefore, from the angle of Security and Economy, need do further improvement to traditional water tap.
Summary of the invention
The purpose of this utility model is that a kind of improved structure of tap will be provided, and adopts the hot-water supply device of this structure assembling not only reasonable in design but also safe and reliable, low cost of manufacture.
The purpose of this utility model is achieved in that this improved structure of tap, comprise valve seat with cold water inlet hole A and Water outlet, it is characterized in that: described valve seat is provided with cold water osculum B towards Water outlet, lead to the cold water osculum C of water heater water intake and lead to the hot water inlet hole D from water heater of connecing of Water outlet, is provided with the control spool that can change cold water osculum B and cold water osculum C flow in the described valve body.
During work, cold water inputs to via cold water inlet hole A in the die cavity of valve seat, and the cavity bottom end face has cold water osculum B and cold water osculum C, and when the start of control spool forward, cold water is directly exported cold water to the water discharge of water faucet head by cold water osculum B.Otherwise, when the reverse start of control spool, cold water enters the water heater heating by cold water osculum C through aqueduct, the hot water of water heater outlet directly exports the water discharge of water faucet head through aqueduct to by hot water inlet hole D, so just can reach the purpose of the output and the flow control thereof of cold water and hot water.
All be made as normally open with the aqueduct of cold water osculum C with the aqueduct that is connected water heater water outlet and hot water inlet hole D because connect the water heater water intake, when making water heater produce hot water, can be because of heating does not produce the pressure transient state, so can make the Security of water heater maintenance 100%.Simultaneously, because the pressure transient problem when having eliminated heating, so need not install Decompression valves and check valve additional, this creation has been reached increases the dual purpose of Security and saving manufacture cost.

Embodiment
See also Fig. 1 and shown in Figure 2, the utility model is a kind of improved structure of tap, mainly comprise the one-body molded of Water outlet 1 and valve seat 2, and there is a retaining ring 4 to revolve a control spool 5, wherein be provided with die cavity 6 in the valve seat 2, an end face is established in die cavity 6 bottoms, and valve seat 2 down extends establishes a base 3, an end face is established in the below of base 3, and the right side of valve seat 2 extends to form Water outlet 1 again.
Seeing also shown in Figure 3 is the plan view of valve seat 2, its cavity bottom is a circular end surface, and the central appropriate location of its left semicircle part is opened a cold water inlet hole A who runs through base 3 below end faces, and the both sides of cold water inlet hole A are provided with fixedly concave point f1, f2 is in order to fixing control spool 5.The top of its right semi-circle part has a cold water osculum B, and cold water osculum B does not run through water tap base 3, and directly the duct in valve body leads to Water outlet 1, and the below of right semi-circle part is provided with a cold water osculum C who runs through base 3 below end faces in addition.
Seeing also shown in Figure 4 is the worm's eye view of valve seat 2, and wherein base 3 belows are provided with an end face, and the cold water inlet hole A that the end face left side is offered leads to die cavity in the valve seat, and connects the input of an aqueduct as cold water.The right has hot water inlet hole D, nearly centre has the cold water osculum C of die cavity in the valve seat and is connected to water heater 7 through aqueduct, the water outlet of water heater 7 interconnects through aqueduct and hot water inlet hole D, and the base end face is provided with fixed hole E in order to secure faucets.Seeing also shown in Fig. 5,6,7 is control spool 5, and it can be divided into close 54 of controlling rod 51, lock ring 52, control body 53 and sealing.The below end face of control body 53 is provided with fixedly projection f3, f4, fixing projection f3 and fixedly establish a cold water inlet hole A ' between the projection f4, top, the right is provided with a cold water osculum C ', a cold water osculum B ' is established in below, the right, and cold water inlet hole A ' and cold water osculum C ', be provided with sealing rod 54 around the cold water osculum B ', when control spool 5 is put into water tap die cavity 6, the fixedly projection f3 of control spool 5 bottoms, f4 aims at the anchor piece f1 on the die cavity bottom end face, f2, relatively, the cold water inlet hole A ' of control spool 5 bottoms, cold water osculum C ', cold water osculum B ' aims at the cold water inlet hole A on the die cavity bottom end face respectively, cold water osculum C (go out cold water and enter water heater 7) and cold water osculum B (go out cold water and directly enter Water outlet 1) through aqueduct.Therefore, as shown in Figure 7, when the controlling party of controlling rod 51 pushes away forward then to opening start to a, and the controlling party of controlling rod 51 to b for controlling out cold water, the controlling party of other controlling rod 51 to c for controlling out hot water.
