Abstract
The utility model discloses a self-closing means of valves, comprising a fixing clip, a floating ball and an outer shell. The self-closing means of valves is technically characterized in that both ends of a lacing wire are respectively connected with a floating ball and a ratchet pawl. Once the floating ball is lifted along with the liquid level, and then the ratchet pawl is driven and separated with the ratchet wheel. Under the action of a spiral spring, a closing claw can quickly close the valve. The device can be used for the automatic closing of liquid valves, and is particularly suitable for residences without enough water pressure of water supply and nobody waits for the water.
Description
The utility model relates to a kind of valve self-closing device.
It is inconvenient monitoring being closed under some occasions of valve by the people, waits at the fire hose in front for water receiving as the resident in the tall building, has expended a large amount of time, and a carelessness will cause the room to flood slightly.On November 7th, 1987 Decree of Patent Office of China application number be 86202849 and be called that the patent of " water tap self-closing device " can address the above problem, it is to rely on float buoyancy in water upwards to promote guide rod, and the drive stay cord is closed the water tap of opening.Have characteristics simple in structure, reliable in action.Deficiency is, because guide rod and float can only be along the position shelf axial motions, makes the container of carrying liquid must place the below of guide rod, so just limited its using scope widely.
The purpose of this utility model is exactly that another kind of simple in structure, reliable in action, valve self-closing device easy to use will be provided.
Key points in design of the present utility model is, utilizes the buoyancy of ball float in liquid, drives the self-closing device that is stuck on the valve by lacing wire, by the spring torsion in this device, valve closed rapidly.
Characteristics of the present utility model are: the position that ball float is installed is unrestricted, can move freely in valve scope far away, so the container of carrying liquid also just has bigger moving range, and is easy to use.In addition, the action of this device throttle down is very rapid, can be at short notice with valve closing, this point be the patent introduced previously can not compare.
Accompanying drawing is the structural representation of this device, and part is described as follows among the figure:
Fixing clamp 1, close pawl 2, valve switch 3, shell 4, energy storage handle 5, ratchet 6, wind spring 7, ratchet 8, ratchet spring 9, lacing wire 10, sebific duct 11, lacing wire fixed card 12, ball float 13, resevoir 14.
Introduce an embodiment of the present utility model below in conjunction with accompanying drawing.
Be equipped with in shell 4 that ratchet 6 and ratchet 6 are coaxial to be fixed wind spring 7 and energy storage handle 5 and closing pawl 2, ratchet 8 one ends contact with ratchet 6, and the other end is connected with lacing wire 10.Ratchet spring 9 is arranged on ratchet 8, and said apparatus is fixed on back (need not take off) on the valve with fixing clamp 1, closes pawl 2 and just in time is stuck on the valve switch 3, and the valve export place is with sebific duct 11, and the other end of sebific duct 11 is connected on the resevoir 14.Fixing ball float 13 with anti-muscle fixed card 12 on the edge of resevoir 14, the other end of ball float 13 links to each other with lacing wire 10.Turn energy storage handle 5 with hand during use, drive valve switchs 3 with valve open, simultaneously wind spring 7 is tightened by closing pawl 2, unclamp hand after, because of the effect wind spring 7 of ratchet 6 with ratchet 8 temporarily can not reset.Liquid in the valve flows in the resevoir 14 through sebific duct 11, and along with the rising of liquid level, ball float 13 is upwards swing also, drives lacing wire 10 and ratchet 8; Compression ratchet spring 9, ratchet 8 separates with ratchet 6.Under the elastic force effect of wind spring 7, close pawl 2 drive valve switchs 3 and rotate rapidly, valve closing.
This device not only can be used for family's water storage, also can be used for the autoshutdown of similar Liquid valve in other industrial trade.
Claims (1)
