Abstract

The invention provides a tap water encryption valve with a self-locking function to solve the problems that an exiting top water encryption valve is complex in structure and bad in safety. A valve rod (2) is connected with a wedge disc (1) in a threaded mode. The top portion of the valve rod (2) is fixedly connected with a valve cover (10). The upper end face of a valve body (3) is connected with the valve cover (10). A first upper blind hole, a first lower blind hole, a second upper blind hole and a second lower blind hole match with each other and are formed in the connection face of the upper end face of the valve body (3) and the valve cover (10). A spring (5) is arranged in the first lower blind hole in the valve body (3) and ejects a stoppage pin (6). Magnetic steel (7) is arranged above the stoppage pin (6). When no external force action exits, the stoppage pin (6) is inserted into the first upper blind hole in the valve cover (10), and an electromagnet (11) is arranged in the second upper blind hole in the valve cover (10). When no external power supply exists, a magnetic core of the electromagnet (11) extends outwards and is inserted into the second lower blind hole in the valve body (3), the valve rod (2) matches with a key (13) in a shaft-hole clearance fit mode, magnetic steel (14) and a power supply (15) are arranged on the key and respectively match with a third blind hole and a fourth blind hole in a clearance fit mode, and the third blind hole and the fourth blind hole are formed in the valve cover, and the third blind hole and the fourth blind hole respectively correspond to the first upper blind hole and the second upper blind hole.

Description

Tap water with auto-lock function is encrypted valve

technical field:

The present invention is relevant to tap water encryption valve.

background technique:

Tap water is encrypted valve and is for part arrearage and urges repeatly the user who does not pay, and is first separated the encryption device of Lock valve by the meter reading staff of water utility, then throttle down, and after it has paid owing water rate, Open valve continues water again.Running water valve is encrypted, can effectively reduces part unit or individual uncontrolled water, refuse to hand over the phenomenon such as water rate, tax evasion water.

The pure Design of Mechanical Structure of the many employings of existing running water valve encryption device, encrypt the special unlocking tool of valve matched, encryption device is mainly made up of parts such as spring, stop pin, magnet steel, on unlocking tool, be furnished with magnet steel, water valve is in the time of locking, and spring promotes stop pin and is positioned at locked position, when release, magnet steel on magnet steel and encryption device on unlocking tool repels each other, and promotes stop pin and exits locked position, rotates unlocking tool and realizes the release of valve encryption device.Adopt pure Design of Mechanical Structure tap water encryption device, principle is simple, but special unlocking tool exists the shortcomings such as principle too simply, is easily imitated.

summary of the invention:

The object of this invention is to provide one simple in structure, the tap water with auto-lock function that Security is good is encrypted valve

The present invention is achieved in that

Valve rod 2 is threaded with flashboard 1, and valve rod 2 tops and valve gap 10 are connected, and valve rod 2 is connected with valve body 3 by bearing 4, valve body 3 tops are connected with valve gap 10, valve body 3 upper-end surfaces with on valve gap 10 junction surfaces, have match first on, in lower blind hole and second, lower blind hole, in first time blind hole on valve body 3, there is spring 5, spring 5 withstands stop pin 6, the top of stop pin 6 is first magnet steel 7, during without External Force Acting, stop pin 6 inserts on first on valve gap 10 in blind hole, in locked position, on on valve gap 10 second, in blind hole, there is electromagnet 11, during without ABAP Adapter, the magnetic core 12 of electromagnet 11 stretches out, insert in second time blind hole on valve body 3, valve body and valve gap are in locked position, valve rod 2 coordinates with key 13 axis holes are moving, there is on the key the second magnet steel 14, power supply 15 respectively with valve gap on the 3rd, four blind holes are moving to be coordinated, the 3rd, four blind holes are respectively with first, blind hole correspondence on two, when power supply 15 is arranged in the 4th blind hole on valve gap, power supply 15 is electrically connected with the coil of electromagnet 11, when the second magnet steel 14 is positioned at the 3rd blind hole on valve gap, the second magnet steel repels the first magnet steel in first time blind hole on valve body 3.

The present invention can realize encryption, the deciphering of running water valve easily, is convenient to waterworks management running water valve, reduces and steals water leakage phenomenon, reduces administration cost; Meanwhile, adopt machinery, electromagnetism several different methods to encrypt running water valve, improved the Security that tap water is encrypted valve.

Compared with prior art, the invention has the beneficial effects as follows:

One, the present invention is organically combined into one machinery, electromagnetism, uses two cipher modes that machinery is encrypted, electromagnetism is encrypted, safe and reliable; Key built-in power is powered to electromagnet, without lay special power supply line on water supply valve, is one tap water encryption safely and reliably valve.On valve body, have spring, spring withstands stop pin, and the top of stop pin is magnet steel, and during without External Force Acting, stop pin inserts in the hole on valve gap, in locked position.Adopt mechanical lock mechanism, principle is simple, easily realizes, and reliability is high, is convenient to promote.On valve gap, have electromagnet, during without ABAP Adapter, the magnetic core of electromagnet stretches out, and inserts in the hole on valve body, in locked position.Adopt electromagnetic locking mechanism, simple structure, has further improved tap water and has encrypted the reliability that valve uses.

Two, valve gap of the present invention and key support the use, can be as required, and the profile of amendment valve gap and key, facilitating waterworks staff to unblank in release tap water encrypts valve, has improved the Security of encryption valve.

brief description of the drawings:

Fig. 1 is the structural representation that the tap water of the embodiment of the present invention is encrypted valve;

Fig. 2 is Key structure figure of the present invention.

embodiment:

The present invention has valve rod 2 to be threaded with flashboard 1, and valve rod 2 tops and valve gap 10 are connected, and valve rod 2 is connected with valve body 3 by bearing 4, valve body 3 tops are connected with valve gap 10, valve body 3 upper-end surfaces with on valve gap 10 junction surfaces, have match first on, in lower blind hole and second, lower blind hole, in first time blind hole on valve body 3, there is spring 5, spring 5 withstands stop pin 6, the top of stop pin 6 is first magnet steel 7, during without External Force Acting, stop pin 6 inserts on first on valve gap 10 in blind hole, in locked position, on on valve gap 10 second, in blind hole, there is electromagnet 11, during without ABAP Adapter, the magnetic core 12 of electromagnet 11 stretches out, insert in second time blind hole on valve body 3, valve body and valve gap are in locked position, valve rod 2 coordinates with key 13 axis holes are moving, there is on the key the second magnet steel 14, power supply 15 respectively with valve gap on the 3rd, four blind holes are moving to be coordinated, the 3rd, four blind holes are respectively with first, blind hole correspondence on two, when power supply 15 is arranged in the 4th blind hole on valve gap, power supply 15 is electrically connected with the coil of electromagnet 11, when the second magnet steel 14 is positioned at the 3rd blind hole on valve gap, the second magnet steel repels the first magnet steel in first time blind hole on valve body 3.
