Abstract

The utility model relates to an automatic closing device for water cut-off, and the utility model is composed of a valve body, a valve cover, a handle, a valve rod, a valve core, and a valve seat. The valve body is provided with a water inlet channel and a water outlet channel which are communicated with each other, the valve cover and the valve body are connected by screws, and a valve rod installation channel is arranged on the valve cover; the handle is arranged at one end of the valve rod, the valve core is fixed at the other end of the valve rod, and the valve rod is positioned at the valve installation channel and the valve seat; the utility model also comprises a plugging device used for blocking the valve installation channel and a valve core locking device, and the valve core locking device can lock the valve core when the valve core locking device is closed. The utility model is the automatic closing device for water cut-off with the purpose that the utility model can be automatically turned off when the water is stopped, and the utility model can not be opened when the water is accidentally supplied.

Description

A kind of self-closing device of cutting off the water

The utility model relates to a kind of liquid control device, particularly a kind of self-closing device of cutting off the water.

At present, many places are arranged, run into through regular meeting and cut off the water because odjective cause makes resident living water can not get ensureing.After cutting off the water, many people forget the valve of having opened or water tap and close, and when normal water supply, the result is that water overflows Kingsoft, has both caused the waste of water, damages not shallow again.

The purpose of this utility model is to provide a kind of and can closes automatically after cutting off the water, suddenly the self-closing device of cutting off the water that supplies water and also can not open.

In order to achieve the above object, the utility model is achieved like this, this self-closing device of cutting off the water comprises: valve body, valve gap, handle, valve rod, spool and valve seat.Valve body has intake tunnel, the exhalant canal that is interconnected, and valve gap is connected with screw with valve body, has a valve rod that passage is installed on the valve gap, and handle is loaded on an end of valve rod, and spool is fixed in the other end of valve rod, and valve rod is arranged in valve rod passage and valve seat are installed; This device comprises that also is used to seal a blocking device and the spool locking device that spool can be locked that valve rod is installed passage when closing.

Described blocking device is made of magnet, spring, magnetic conduction iron plate and seal washer, and described magnet is fixed on the valve body, and spring and magnetic conduction iron plate are contained on the valve rod, and seal washer is fixed on the valve rod, and its periphery is pressed between valve body and the valve gap.

Described spool locking device comprises locking reed, pressing plate, locking bayonet socket, taper unblank cover and Returnning spring, and described locking reed places on the valve gap and is screwed by pressing plate, and unblank cover and Returnning spring of taper is loaded on the valve rod respectively.

Described spool locking device comprises knob, stop pin, ball, screw and Returnning spring, described knob and valve gap link with ball is movable, stop pin crosses on valve rod, and ball is loaded in the knob with the screw sealing, and Returnning spring is loaded in knob and the space that valve gap combines.

The utility model self-closing device of cutting off the water has following advantage: because a locking device is housed on valve rod, therefore, even valve or water tap forget that closing the utility model can close automatically when cutting off the water, also can open when supplying water again and cause waste and infringement.

Below in conjunction with accompanying drawing two mode of executions of the present utility model are described.

Fig. 1 is the sectional view of its spool of the utility model mode of execution when being positioned at closed position.

Sectional view when Fig. 2 is positioned at open position for its spool of the utility model mode of execution.

Fig. 3 is the sectional view of its spool of the utility model second mode of execution when being positioned at closed position.

Fig. 4 is Fig. 3 A-A sectional view.

Fig. 1 and Fig. 2 show cut off the water first mode of execution of self-closing device of the utility model.Valve body 1 has intake tunnel 7, exhalant canal 8, the valve seat 6 that is interconnected, valve gap 2 is connected with valve body 1 usefulness screw, has a valve rod that passage 9 is installed on valve gap 2, and handle 3 is loaded on an end of valve rod 4, spool 5 is fixed in the other end of valve rod 4, and valve rod 4 is arranged in valve rod passage 9 and valve seat 6 are installed.

Fig. 1 is the closed condition of self-closing device of cutting off the water, when cutting off the water, because valve rod deadweight and the sucking action that is installed in magnet 10 and magnetic conduction iron plate 12 on the valve body 1 sink valve rod 4, the spool 5 that is fixed on the valve rod 4 is inserted in the valve seat 6, elastic force at spring 11 is issued to the purpose of closing, and when cutting off the water, it can be closed automatically, therefore, people needn't worry also that when forgetting throttle down or water tap water can flow out.

Shown in Figure 2 is the self-closing device opening state of cutting off the water, when normal water supply, the promotion taper is unblanked to overlap 18 crowded moving locking reeds 16 and is made its bayonet socket 17 that goes out of lock, and the spool 5 and the gasket seal 13 that are fixed on the valve rod 4 are floated along with the pressure of water is past, spool 5 lifts off a seat 6, thereby makes water Channel Group.

Fig. 3 and Fig. 4 show cut off the water second mode of execution of self-closing device of the utility model, and except that the spool locking device was different from first mode of execution, other structures of the self-closing device of cutting off the water were identical.Its spool locking device comprises knob 31, guide groove 32, stop pin 33, screw 34, ball 35 and Returnning spring 36.Knob 31 and valve gap 35 movable bindings of 2 usefulness balls, stop pin 33 crosses on valve rod 4, and ball 35 is loaded in the knob 31 with screw 34 sealings.Just often, because the effect of hydraulic pressure is valve rod 4 jack-up, stop pin 33 is in the guide groove 32; When undesired the causing when cutting off the water of supplying water, the device internal pressure disappears, simultaneously under the effect of magnetic force, stop pin 33 on the valve rod 4 moves downward and shutoff device along the guide groove 32 in the knob 31, position when device is closed just in time is that stop pin 33 moves to the spatial position between knob 31 and the valve gap 2, knob 31 is under the elastic force effect of Returnning spring 36 at this moment, and knob 31 rotates an angle automatically, and the stop pin 33 on the valve rod 4 departs from guide groove 32.When resuming water supply, because of stop pin 33 withstands on the knob 31, the utility model is closed all the time; When opening the guide grooves 32 in the knob 31 are threaded to the relative position with stop pin 33, because the effect of hydraulic pressure, valve rod 4 is by jack-up, and the utility model promptly is opened.
