Background technique
In actual life, cutting off the water is the problem that people often run into.During cutting off the water, people habitually open water nozzle toward the contact meeting, and usually can not be not closed completely because of having water, perhaps forget and close water nozzle.If water nozzle do not close, and at home nobody the time water, will cause the serious consequence of flooding the building.This not only can waste a large amount of water, also can be to oneself causing very big economic loss, even also cause very big loss to others, influence neighborhood relationship.For addressing this problem, I have developed a kind of " health care dam self closing stop valve ", and have applied for that on April 6th, 1994 Chinese patent, the patent No. are ZL94228256.6.This valve is installed in the front of water tap, and it has the self-closing function of cutout, plays automatically when cutting off the water and closes, and prevents the effect of metalling run out.This valve mainly is made up of valve body, valve gap, valve rod, rectangular seal pad, diaphragm seal pad, magnetosphere, seal ring and pad etc.Rectangular seal pad and pad are installed in the lower end of valve rod, and magnetosphere and seal ring are positioned on the communication port of valve body.When water was arranged, the pressure of water made valve rod and rectangular seal pad remain on the top of seal ring, and valve is kept opening state.When cutting off the water, valve rod and rectangular seal pad have lost the supporting effect of hydraulic pressure, and under the effect of the magnetic force of the elastic force of itself gravity, diaphragm seal pad and magnetosphere, valve rod falls, and the rectangular seal pad is pressed on the seal ring of communication port, with valve closing.When coming water again, valve also can not be opened automatically, thus the generation of the phenomenon that prevented to metal run out.But in actual use, this valve is because the restriction of itself structure, and using effect can't be entirely satisfactory, and also exists several problems that are difficult to overcome.For example, this valve is because the volume of magnetosphere is excessive, and the distance of the attraction pad on valve rod is nearer again, therefore, magnetosphere is too big to the suction of pad, in addition, the elastic force of diaphragm seal pad also is difficult to determine, so just makes valve occur misoperation easily at low pressure area, promptly is lower than 0.5kg/cm in water pressure
2The time valve close automatically, so this valve can't normally use in the lower area of hydraulic pressure.In addition, the sealing surface of rectangular seal pad and seal ring is the plane, and surface of contact is bigger, and therefore, valve closing is not tight, behind valve closing, and the phenomenon that still has seepage to drip.
Summary of the invention
The technical problems to be solved in the utility model is, overcomes existing self closing stop valve and is not closed completely, and low pressure area is prone to the problem of misoperation, and a kind of good seal, water saving safety valve that reliability is high are provided.
The utility model has a valve body, valve gap and valve rod are housed above the valve body, its special way is, between valve body and valve gap, upper valve body is housed, corrugated tower cover is housed in upper valve body, the valve plug that matches with the valve body communication port is housed below valve rod, permanent magnet is housed in valve plug, the water gland of inhaling mutually with it is housed on permanent magnet, in communication port, be equipped with one with its permanent magnet of inhaling mutually of valve plug permanent magnet.
In order to improve the reliability of sealing, the sealing surface of communication port is the conical surface on the valve body.
The utility model is provided with a permanent magnet respectively in valve plug and communication port, and a water gland of inhaling mutually with permanent magnet is set on valve plug, during valve closing, permanent magnet on the valve plug is inhaled mutually with the permanent magnet in the communication port, during unlatching, permanent magnet on the valve plug is inhaled mutually with top water gland, and, a upper valve body is installed between valve body of the present utility model and valve gap, increased space in the valve, avoided the phase mutual interference of magnetic force, and replaced the diaphragm seal pad with corrugated tower cover, its elastic force is under control, thereby improved the reliability of valve event, overcome the disadvantage that misoperation appears in valve easily, therefore, the utility model is not subjected to the influence of water pressure fluctuations, can both proper functioning in the pressure range of setting.
Communication port sealing surface of the present utility model is the conical surface, with between the seal ring for line contacts, improved the reliability of sealing, solved the not tight problem of valve closing.
