Abstract

The utility model relates to a health cut-off self-closing valve used for self-closing and automatic cutoff when the cut-off pipeline is unclogged again, which has the function of magnetization to the flowed liquid. The utility model is mainly characterized in that a magnetic coil is arranged on a circulation mouth of a baffle plate on the valve body, a sealing ring is arranged in the magnetic coil, and a pad attracting the magnetic coil is arranged at the lower end of a valve rod. The utility model has the advantages that the magnetic coil can attract the pad on the valve rod so as to close the valve automatically when cutoff of the flow occurs so that the liquid can not flow out of the pipeline when the pipeline is unclogged again; the magnetic coil performs magnetization function to the flowed liquid, the magnetization of drinking water can improve water quality, and the function of health care can be achieved; the mode of opening or closing is easy; the valve can move up and down freely; the cutoff is reliable when the valve is closed.

Description

Health cut-off-self-closing valve

The utility model belongs to a kind of valve, and particularly a kind of closing automatically when pipeline cutout is logical again dammed, and to the health care that the liquid that flows through has the magnetization self closing stop valve that dams.

Before the end outlet place of civilian tap water and other liquid devices (before being water tap or valve), for the ease of maintenance or replacing valve, generally all be provided with hand stop valve, to control the break-make of liquid in the pipeline thereafter, but hand stop valve only possesses the function that opens and closes pipeline, and just can reach the purpose of switching after must manual activity; Usually hand stop valve is in normally open, does not close if pipeline brings out the valve of mouth, when cutout in the pipeline is logical again, liquid will " run and emit ", not only can cause the waste of resource, and may flood the facility that decreases other, and injure the use and the safety of facility.

In order to prevent that above-mentioned phenomenon from taking place, people have developed many valves with self-closing function, the Chinese patent that is called " Water-saving valve " as name, application number is 90218359.1, be somebody's turn to do " Water-saving valve " mainly by last, following valve body, valve gap, valve rod, composition such as spring and sealing gasket, between the inlet of valve body and the passage of outlet dividing plate is arranged, be processed with communication port on the dividing plate, the middle part of valve rod is equipped with the arc sealing gasket, the top of valve rod connects the eccentric tugboat that has slideway, between valve gap and tugboat, be placed with ball, utilize eccentric tugboat to drive on the valve rod, following motion is closed communication port or open.Though this valve has the function of cutting out automatically when cutout is logical again, need pull the pressure handle all the time when opening, can not be from hand, the long-time use then is inconvenience deeply; In addition, the structure more complicated of this valve, component are more, and cost is also higher, and this valve can only use as water tap, adopts this valve then need pull down water tap on the former pipeline, causes certain waste.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of when the pipeline cutout is logical again, closing automatically to dam, both can use separately, also can with the valve coupling on original pipeline, and to the health care that the liquid that flows through has the magnetization self closing stop valve that dams.

The utility model is achieved in that

It has a valve body, between the inlet of valve body and the passage of outlet dividing plate is arranged, and is processed with communication port on the dividing plate; Valve gap is installed on valve body, in valve gap and valve body valve rod is installed, dish-shaped sealing gasket is installed between valve gap and valve body, the middle part and the valve rod of dish-shaped sealing gasket are fixed together, and emerge to prevent liquid; On the communication port of valve body dividing plate, magnetosphere is housed, seal ring is housed in the magnetosphere; Be equipped with in the lower end of valve rod can with magnetosphere mutually adhesive pad and with the sealing gasket that seal ring matches, utilize magnetosphere to attract pad on the valve rod, the sealing gasket of valve rod lower end is pressed on the seal ring in the magnetosphere, valve is closed automatically.

The utility model compared with prior art has following advantage:

1, on the communication port of dividing plate, magnetosphere is housed, can be during cutout with the pad adhesive on the valve rod, automatic-closing valve prevents to run when liquid is logical again and comes up, and avoids the wasting of resources.

2, magnetosphere has magnetization to the liquid that flows through in the valve, is magnetization for the first time when liquid flows through in magnetosphere, and liquid flow be magnetization for the second time outside magnetosphere the time, thus change liquid internal molecular characterization; To the magnetization of potable water, then improved water quality, play a role in health care.

3, simple in structure, component are few, and cost is low; Opening/shutting mode is easy, and upper and lower motion is dammed under the closed state reliably nimbly and freely; The irrotationality flap is pressed process, and mechanical wear is little; Both can use separately, also can with the valve coupling on original pipeline, or replace opening and closing device on original pipeline.

Provide embodiment of the present utility model below in conjunction with accompanying drawing:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the plan view of Fig. 1.

As shown in the figure, the utility model has a valve body 1, and an end of valve body 1 is outlet, and the other end is inlet, between the passage of inlet and outlet dividing plate is arranged, and is processed with communication port on dividing plate; Valve gap 4 is installed on valve body 1, and valve gap 4 usefulness screws 3 are fixing; In the center hole of valve body 1 and valve gap 4 valve rod 5 is installed, valve rod 5 can be upper and lower mobile in the center hole of valve gap 4, in the lower end of valve rod 5 set screw nut 6 is installed; In order to prevent that valve gap 4 and valve rod 5 from leaking, dish-shaped sealing gasket 2 is installed between valve body 1 and valve gap 4, the middle part of dish-shaped sealing gasket 2 is sleeved on the lower end of valve rod 5, and is fixed together with valve rod 5; Magnetosphere 10 is housed on the communication port of valve body 1 dividing plate, magnetosphere 10 sticks with glue on dividing plate, in the inside of magnetosphere 10 seal ring 9 is housed, the entry end of the center hole outlet deflection valve body 1 of seal ring 9, liquid is flowed earlier backward, and then mobile forward through the both sides of magnetosphere, so that liquid is further magnetized; Also be equipped with in the lower end of valve rod 5 can with magnetosphere 10 pad 8 of adhesive and the sealing gasket 7 that matches with seal ring 9 mutually so that with valve closing.

The utility model can use separately, also can with the valve coupling on the former pipeline.When using separately, valve rod 5 is upwards mentioned, liquid can flow out, at this moment, because the pressure of entry end is greater than outlet end, pad 8 draws back the back attraction force with magnetosphere 10 to be weakened, and dish-shaped sealing gasket 2 has certain elastic force, therefore, valve rod 5 can not fall, and valve remains on opening state; When closing, only need valve rod 5 is depressed, make pad 8 and magnetosphere 10 adhesives, valve can be closed; When stopping in the pipeline, entry end pressure is zero, and pad 8 and magnetosphere 10 automatic adhesives are with valve closing.During with valve coupling on original pipeline, the utility model can be connected on the front of former valve as stop valve, valve rod 5 can be pulled upwardly at ordinary times, remain on normal opening state, after the cutout, valve is closed automatically in the pipeline, also can not occur running and emits phenomenon because of forgetting closing valve when pipeline is logical again.
