Abstract

The utility model relates to a stopping water self-closing tap, comprising a valve body, a valve rod and a valve core. The valve rod and the valve core are assembled in the valve body. A water pressure sensor is arranged in a cover body fixed on the valve body. One end of the water pressure sensor is communicated with the end of a water inlet of the valve body through a conduit pipe, and the other end is connected with a contact of a locking plate hinged in the cover body. A locking hook of the locking plate is meshed with a block table of a rotary disk which is sheathed on the valve rod and is tensed through a spring. A block pin of the rotary disk is clamped on a deflector rod which rotates following the valve rod. The utility model has the advantages of simple structure, easy fabrication, safe and convenient usage, and reliable self-closing control. The utility model can fundamentally prevent water escaping disasters from occurring.

Description

Water-stopping self-closing water is chewed

The utility model relates to the water that a kind of daily life uses to be chewed, and the water saving safe water that can close automatically during particularly a kind of cutting off the water is chewed.

At present, tap water pipe line stops suddenly supplying water and the user forgets to close Shui Zui, often takes place because of valve opening causes the thing of the disaster of metalling run out when supplying water again.For preventing the generation of the above-mentioned disaster of metalling run out, some are floating, and waft formula or bolt-type water-stopping self-closing water is chewed and is arisen at the historic moment.The control mechanism that these water are chewed remains that spiral is opened or the close type structure, because of its control structure complexity, the manufacture cost height, uses cumbersome, so obstruction its apply.Controlled in addition structural limitations is easy to produce misoperation, influences its self-closing performance, and therefore, the phenomenon of metalling run out still happens occasionally, and both wastes water, and causes the loss of property again.

The purpose of this utility model provides a kind of water-stopping self-closing water and chews, and it is simple in structure, makes easily, and safe in utilization, convenient, self-closing control is reliable, and the disaster that fundamentally prevents to metal run out takes place.

The purpose of this utility model is achieved in that this device comprises valve body and assembling valve rod and spool within it, wherein be fixed in the cover body on the valve body hydraulic pressure sensor is arranged, the one end is communicated with valve inleting water mouth end by conduit, the other end joins with the locking plate contact that is hinged in the cover body, the latch hook of locking plate be sleeved on valve rod on and be meshed with the rotating disk of tensioned retaining platform, the rotating disk backing pin is stuck on the driving lever that rotates with valve rod.

Because valve inleting water mouth end of the present utility model adopts existing water to chew the structural type that is connected with tap water pipe line, on valve body, install the cover body that has hydraulic pressure sensor, and an end of hydraulic pressure sensor is communicated with valve inleting water mouth end by conduit, the other end and locking plate contact join, so the control structure of this device is simple, only need handle with sleeve, when spool is opened, utilization is dialled the rotating disk backing pin with the driving lever that valve rod rotates, drive rotating disk rotates thereupon, retaining platform on it is meshed with the lock hook of locking plate, can supplies water.In case cut off the water, valve inleting water saliva is pressed and is eliminated, do not have in the hydraulic pressure sensor to press and shrink, when the locking plate contact that contacts is with it moved under adjusting spring action thereupon, the lock hook of locking plate breaks away from rotating disk retaining platform, and rotating disk resets under the effect of tension spring, when rotating disk backing pin promotion driving lever drive valve rod resets, the spool of valve rod end is closed, and this chews the purpose of water-stopping self-closing to water.This water is chewed above-mentioned self-closing control system and is not only made easily, use, easy for installation, and open and close flexibly, reliable, as long as running water pipe is cut off the water, hydraulic pressure sensor moves immediately, actuate valve stem self acting stop valve core, chew the disaster of metalling run out that causes and take place so forget Guan Shui when preventing to cut off the water effectively, avoid the waste that causes because of metalling run out and the loss of property.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a kind of concrete structure schematic representation of the utility model.

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

Describe concrete structure of the present utility model in detail according to Fig. 1-2.This device comprises valve body 1, has the valve rod 2 of handle 4, spool, hydraulic pressure sensor 3, have backing pin 5 and retaining platform rotating disk 8, have the parts such as locking plate 15 of lock hook and contact.Wherein valve body 1 inlet end adopts general linkage structure, and its specification size should be selected according to the specification of tap water pipe line.Spool is made up of by valve block existing, promptly by utilizing sealing gasket 13 to be packed in the guide plate that has water passage hole 12 of crossing water cavity in the valve body 1, and the rotation that is assembled in valve rod 2 ends sheet 11 formations that intercept water.Valve rod 2 axially encapsulates by seal ring and trim ring 7, and circumferentially locatees with driving lever 6, and driving lever 6 is circumferential when mobile, and valve rod 2 also rotates thereupon.Cover body 9 is packed on the valve body 1, is assembled with the rolling spring 10 that bellow type hydraulic pressure sensor 3 and tensioning are sleeved on the rotating disk 8 on the valve rod 2 in it.One end of hydraulic pressure sensor 3 is communicated with valve body 1 inlet end by conduit 14, and the other end joins with locking plate 15 contacts that are hinged in the cover body 9.Backing pin 5 on the rotating disk 8 is stuck on the driving lever 6 that rotates with valve rod 2.Retaining platform on the rotating disk 8 is meshed with the lock hook of locking plate 15.Locking plate 15 utilize stationary axle 16 and by stretched spring 17, adjust the accent spring hinge that bolt 18 forms and be connected in the cover body 9.Utilize the adjustment spring to adjust locking plate 15 contacts and the contacted stroke of hydraulic pressure sensor according to the pressure in the running water pipe, to guarantee that locking plate 15 can change according to the variation of hydraulic pressure thereupon, the size of running water pipe internal pressure reaches no matter can keep the contact of locking plate tightly to contact with the end of hydraulic pressure sensor.

During use, at first regulate and adjust bolt according to the hydraulic pressure in the tap water pipe line, make stretched spring 17 with hydraulic pressure sensor 3 ends (also can according to usage requirement in advance adjust, be directly installed on tap water pipe line on) of the tight contact of locking plate 15 contacts under hydraulic action.Pull handle 4 rotation valve rods 3, can realize the opening and closing that water is chewed.When need fixed handle 4, with driving lever 6 promote backing pins 5 drive rotating disks 8 turn to retaining platform on it when being meshed with the lock hook of locking plate 15 only, the rotation of the spool sheet 11 that intercepts water also goes to limit position with valve rod 2, with the water passage hole complete opening of guide plate 12, this moment the current maximum.If cut off the water suddenly in the running water pipe, then lose hydraulic pressure in the hydraulic pressure sensor 3, the contact that its end retraction drives locking plate 15 moves thereupon, under the effect of spring 17, locking plate 15 rotates around stationary axle, makes lock hook on the locking plate 15 break away from retaining platform on the rotating disk 8 immediately automatically, and rotating disk 8 resets under spring 10 effects, backing pin 6 on it drives valve rod 2 and forwards initial position to, and spool is closed automatically.When running water pipe came water again, water was chewed and is closed automatically, the phenomenon of can not metalling run out.
