Abstract

The utility model relates to a self-close type magnetic opening stop valve, composed of a valve disk, a valve body, an upper magnetic disk, a lower magnetic disk, a liner plate, a press cover, a handle, etc. The utility model is characterized in that two magnetic disks are arranged inside and outside the valve body respectively. A sealing liner plate is arranged between the two magnetic disks. The valve body is completely closed. When the utility model is used by the people, the handle is rotated. The upper magnetic disk drives the lower magnetic disk through the magnetic field force. A valve is opened. When a hand leaves the handle, the handle is automatically reset. The valve is closed. The separation of the handle and the valve disk is achieved. The utility model can be used for each water supply field of a water boiler, a toilet, etc.

Description

Self-close type magnetic opening stop valve

The invention belongs to the mechanical engineering part, the valve class device in the common engineering.

Normally used water valve generally is the cock-type valve, and the defective of this valve is, leak because of using the wearing and tearing bad sealing at the control position of valve, and the control position usually outwards dabbles during use, and opens and closes effort, and feel is bad.

At toilet train and some other occasions self-closing stop valve, hand-held handle firmly presses down during use, and because of handle and valve disc are integral by connection rod set, the control position takes regular exercise and wearing and tearing are also arranged and leaks, and this valve feel is poor, and effort is used also inconvenience.

The objective of the invention is to design a kind of self-closing magnetic that is used for hot water and other aspect and open stop valve.Owing to adopted magnetic force to drive the open method of valve, and realized separating fully of handle and valve disc, thereby overcome the leakage shortcoming of traditional cock-type valve and self-closing stop valve, can close automatically during use, but manual-lock again, thereby realized easy to use, good hand touch and leak free purpose.

Fig. 1 is a whole assembly structure chart of the present invention.

Fig. 2 is a plan view of the present invention.

Fig. 3 is the disk structure figure of going up of the present invention.

Fig. 4 is disk structure figure down of the present invention.

Self-closing magnetic is opened stop valve and is made up of plug screw (1), rubber asbestos packing (2), nut (3), packing ring (4), rubber pad (5), valve disc (6), valve body (7), time disk (8), flat key (9), backing plate (10), last disk (11), gland (12), handle (13), bolt (15).

Last disk (11) is made up of last disk cartridge (16) and permanent magnetic iron (17) (18).

Following disk (8) is by disk cartridge (19) and permanent magnetic iron (20) (21) are formed down.

The disk cartridge (16) of last disk (11) studs with four cylinder type permanent magnetic irons (17) (18), magnet (17) (18) when putting into adjacent magnet polarity opposite.Stick with glue solid between magnet and the disk cartridge.Last disk (11) one ends have a shaft to be connected with handle (13).Last disk (11) is a backing plate (10) that is used for sealed valve body (7) between last disk (11) and the following disk (8) in gland (12), and thickness is less than 2 millimeters.The disk cartridge (19) of following disk (8) studs with four cylinder type permanent magnetic irons (20) (21), magnet (20) (21) when putting into adjacent magnet polarity opposite.Following disk (8) one ends have a shaft (14), and valve disc (6) is fixed by rubber pad (5), packing ring (4), nut (3).Following disk (8) is installed in the valve body (7), and following disk (8) and valve body (7) respectively have a groove, and two groove places put into flat key (9), in case disk (8) rotates down.Valve body (7) is that copper becomes, and last disk cartridge (16), following disk cartridge (19) and backing plate (10) all are to be made by nonferromagnetic material.When last disk (11) and each corresponding permanent magnetic iron of following disk (8) are the opposite sex, disk adhesive up and down, valve disc (6) is closed the water outlet of valve body (7), and the position of handle (13) is consistent with the water outlet of valve body (7).There is a circular hole lower end of valve body (7), the valve disc (6) of can packing into.Rubber asbestos packing (2) and plug screw (1) are with valve body (7) lower end closed.There is an opening upper end of gland (12), and the size of opening can hold handle (13) and move clockwise and counterclockwise, and the both sides of opening are the limit positions of handle (13).When handle (13) rotated counterclockwise limit position, the water outlet center line angle of the center line of handle (13) and valve body (7) was less than 90 degree, and optimum angle is 88-89; When clockwise rotating limit position, angle is greater than 90 degree, and optimum angle is the 91-92 degree, and last disk (11) is put into gland (12), and gland (12) and valve body (7) are fixing by bolt (15), and backing plate (10) is compressed.

When people use, with hand as required clockwise or rotate counterclockwise handle (13), last disk (11) rotates thereupon, slowly stagger by the position by there is a natural attraction between the sexes for the corresponding magnet of disk up and down, become the same sex gradually and repel each other, disk (8) is moved downward, through disk axis (14) drive valve disc (6) is downward down by the magnetic force effect, valve opening, water flows out through water nozzle from pipeline.After using up, the handle that rotates counterclockwise (13) is as long as hand from handle (13), makes disk (11) drive handle (13) automatically reset valve closing by the pressure of water and the effect of magnetic force.The handle that clockwise rotates can make valve open for a long time, also can automatically reset to back rotation handle (13) slightly with hand when closing.

The present invention uses the magnetic field force Open valve owing to used permanent magnetic iron, and handle and valve disc are isolated fully, thereby have realized the unlatching good hand touch, leak free purpose. Can be widely used in each feedwater fields such as water heater toilet.
