Abstract

The utility model relates to a multifunctional water valve, which is mainly provided with an additional hand control water valve on a valve body of an electromagnetic water valve, wherein, a water inlet and a water outlet of the hand control water valve are separately communicated with a general water inlet pipe and a general water outlet pipe of the valve body, and a ball check valve is installed in the general water outlet pipe. The utility model has the advantages of reasonable and simple structure, convenient installation and operation, etc., can automatically replenish cold water under the control of a control device, can mix cold water into hot water in a manual mode when the hot water is used, can prevent the hot water from flowing backward, and is suitable to be matched with a solar water heater.

Description

Multi-functional water valve

The utility model relates to a kind of valve, but but particularly a kind of not only Electromagnetic Control but also hand-guided and can prevent the water valve of backflow.

Solar water heater is energy-conservation because of having, advantage such as pollution-free extremely people is welcome and is entered increasing family rapidly, need not someone wait in last water process in order to make solar water heater, some and the matching used supervisory device of solar water heater have possessed the automatic loading water function, but also do not supply the special-purpose water valve of automatic loading water in solar water heater at present, generally all use the electromagnetism water valve of washing machine to substitute, but these water valves are specially for machine design, the electromagnetism water valve is only arranged, function singleness, be installed in the water system of solar water heater and have unreasonable structure, install and use shortcomings such as inconvenience, need add crossover sub at the water valve two ends when mounted could be connected with pipeline; In order when having a bath, to mix cold water, or when having a power failure, also can replenish cold water to water-heater water tank, also must adjunction bypass water pipe and manual water valve, install and use all inconvenient.

But but the purpose of this utility model is to design a kind of simple and reasonable, easy to install, not only Electromagnetic Control but also hand-guided and can prevent the multi-functional water valve of backflow for solar water heater.

Multi-functional water valve of the present utility model mainly is to have increased manual water valve on the electromagnetism water valve, and described manual water valve is installed on the valve body of electromagnetism water valve, and the water intake of manual water valve and water outlet communicate with water inlet manifold and total outlet pipe of valve body respectively.In order to prevent that the water in the water heater is back in the water supply network, a ball check valve is housed in total outlet pipe of valve body.

Accompanying drawing is an an embodiment's of the present utility model structural representation.

Referring to accompanying drawing, multi-functional water valve among the figure comprises electromagnetism water valve and manual water valve, wherein, the electromagnetism water valve comprises electronic water-inlet cavity 7, electronic outlet pipe 8, water inlet manifold 6 and the total outlet pipe 15 on electromagnetic coil 1, spring 2, movable core 3, rubber ring 4, the valve body 5, its electronic water-inlet cavity communicates with water inlet manifold, electronic outlet pipe communicates with total outlet pipe, at ordinary times, movable core 3 gets lodged in rubber ring 4 between electronic water-inlet cavity 7 and the electronic outlet pipe 8 because of the elastic force of spring 2, make water inlet manifold 6 obstructed with total outlet pipe 15, the electromagnetism water valve is closed; When electromagnetic coil was connected power supply, movable core 3 was attracted and makes rubber ring 4 leave electronic water outlet 8, and water inlet manifold 6 is communicated with total outlet pipe 15, and water valve is opened, and realizes automatic loading water.Manual water valve comprises manual water intake 9, manual water outlet mouth 10, manual spool 11, valve core cap 12 and handle 13, its manual water intake and manual water outlet mouth communicate with water inlet manifold and total outlet pipe respectively, valve core cap is installed in manual spool on the valve body, manually spool is optional with the spool of ceramic ball valve water tap or the spool of other model water tap, handle with sleeve can make manual spool open or close, and the regulating handle angle is the adjustable gate size, can be implemented in and regulate the cool water quantity of mixing when using hot water.Because the hydraulic pressure of water supply network may be lower than the hydraulic pressure in the solar water heater sometimes, supply water or cut off the water etc. temporarily as step-down, at this moment, as open water valve and water in the water heater just may take place be back to phenomenon in the water supply network, in order to prevent the generation of backflow phenomenon, the ball check valve 14 of in total outlet pipe, packing into, the diameter of this ball check valve should be less than the internal diameter of total outlet pipe greater than the aperture of the water inlet of total outlet pipe, and the plastic hoop 16 that at the mouth of pipe place of total outlet pipe a center is housed criss-crossing is arranged prevents that ball check valve from deviating from outside total outlet pipe, hydraulic pressure just often, the hydraulic pressure of water inlet manifold is greater than the hydraulic pressure of total outlet pipe, ball check valve by hydraulic pressure to the outlet of total outlet pipe and do not influence water inlet, when pipe network water pressure is lower than water heater hydraulic pressure, ball check valve is blocked current by hydraulic pressure to the water inlet of total outlet pipe, can effectively stop hot water and flow backwards.For the ease of being connected, on water inlet manifold and total outlet pipe, be processed with and the corresponding screw thread of water pipe adapter with water supply line.During installation, the water inlet manifold of this water valve is connected with running water pipe, and water pipes such as the intake pipe of total outlet pipe and solar water heater and bathing are connected, and electromagnetic coil links to each other with the water-feeding controller of controller.

But the utlity model has simple and reasonable, easy to install, the not only automatic control of electromagnetism but also can be artificial Manually control and can prevent the advantage such as backflow of operation can realize automatically replenishing cold water under the control of control device, Mix cold water with manual mode when using hot water, the most suitable and solar water heater supports the use.

Claims (2)

1. a multi-functional water valve comprises the electromagnetism water valve, it is characterized in that also comprising manual water valve, and described manual water valve is installed on the valve body of electromagnetism water valve, and the water intake of manual water valve and water outlet communicate with water inlet manifold and total outlet pipe of valve body respectively.

2. multi-functional water valve as claimed in claim 1 is characterized in that in total outlet pipe of valve body a ball check valve being housed.
