Abstract

The utility model discloses an intelligent card type heat supply control valve, comprising a power supply source, electromagnets, a valve body, a valve core, a smart card and a driving circuit. The driving circuit is the actuating mechanism of the smart card, the valve core is provided with two parallel medium channels, the valve core and the driving electromagnet are connected by a driving stop lever, the locking electromagnet is matched with the driving stop lever and locks the switching positions of the valve core, and the valve body is additionally provided with a water inlet pipe and a water return pipe of the valve, a water inlet pipe and a water return pipe for a radiator, and a water inlet closure pipe and a water return closure pipe of the valve. The utility model has a completely identical pairing mode of radiators to the present radiator, achieves the requirement of buying cards before heating for users, and makes the fee collecting work for heat supply active.

Description

The intelligent card type heat supply control valve

The utility model is a kind of intelligent card type heat supply control valve that is used for heating system

North of china in winter heating is born by the heat supply company of various places, and the receipts heating fee has become a great problem of each heating enterprise, particularly casual household resident's heat expense more is difficult for collecting, receive the hot difficulty of taking for solving, people have developed a kind of locked valve, control each household intake pipe, though it has accomplished a family one valve, pay dues and promptly open the valve heating, otherwise locked valve, not heat supply, but it is not locked also to exist return pipe, still have water in the radiator, the deficiency of the freezing heating installation of meeting, and the passive charge method that does not change " charge of visiting " yet.

The purpose of this utility model is, for overcoming the deficiency of prior art, provides a kind of intelligent card type heat supply control valve.

Following mode can realize the utility model:

Comprise power supply, electromagnet, valve body and spool, it also comprises a smart card and a drive circuit, drive circuit is the actuator of smart card, two parallel medium channels are arranged on the spool, also be provided with the valve intake pipe on the valve body, the valve return pipe, connect heater inlet pipe and connect the heating installation return pipe, valve intake pipe and valve return pipe advance through valve, the backwater closure tube is communicated with, DM is connected with spool by driving locking lever, the locking electromagnet cooperates opening of locking spool with the driving locking lever, close the position, the drive circuit output terminal connects DM and locking electromagnet respectively.

The utility model adopts opening of smart card control heat supply valve, close and operating time of valve, accurately and reliably, in the heating system of vertical series connection, can control the heating installation at each family separately, and other user in the not influence system, the user initiatively pays dues and buys card, can drive valve and connect heating installation, after the heating phase, smart card disabled, valve is closed again, and heating charge is changed from passive to active, if do not pay dues, valve place closed condition in pent heating installation, is not intake in the radiator, thereby prevent bursting by freezing heating installation, mounting type of the present utility model and installation dimension and existing radiator corresponding size are identical.

Fig. 1 is the utility model overall structure schematic representation (a valve closing state).

Fig. 2 is the valve opening state schematic representation.

Fig. 3 is smart card and drive circuit functional-block diagram.

Fig. 4 is the mounting type schematic representation of the utility model and radiator.

Embodiment:

Spool 6 places in the valve chest, two parallel medium channels 9 are arranged on the

spool

6,10, also be provided with valve intake pipe 1 and valve return pipe 2 on the valve chest, valve intake pipe 1 and valve return pipe 2 advance through valve, backwater closure tube 8 is communicated with, drive locking lever 7 and connect spool 6 and DM 11, drive a plurality of 45 degree chamferings are arranged on the locking lever 7, cooperate with 45 degree chamferings of the movable core of locking on the electromagnet 12, drive on the locking lever 7 and spring 5 is arranged near the spool end, smart card 14 is PIC16C6XX series or PIC16C5X series monolithic system, controlling and driving circuit 13, make

electromagnet

11,12 according to needed working method action, and detection

system power supply

15,16, valve is opened, close the transmission of control signal, the system component monitoring, System production time clocks etc., working procedure of the present utility model is as follows: will set then finish and qualified effective smart card be inserted in the smart card dedicated slot of intelligent card type heat supply control valve, at this moment, smart card can command all system to carry out following work, detect

electromagnet

12,11

working power

15,16, detect the qualified further work that carries out, otherwise cycle detection, smart card 14 sends instruction and makes it to connect the power supply of electromagnet 11 for drive circuit 13, at this moment electromagnet 11 energising adhesives, drive on the spool 6 and carry, make two parallel medium channels 9 of

spool

6,10 connect with the intake pipe 1 of valve and heater inlet pipe 3, valve return pipe 2 and heating installation return pipe 4 are connected, this moment, valve was in the enable possition, heating installation is connected, 12 of electromagnet movable core locks locking lever 7 and spool 6 again simultaneously, behind the valve open, smart card 14 enters the energy-saving run state of low power consumption, the CPU sleep, its internal clocking carries out timing to the operating time, when finish the working time of setting (end of heating phase), smart card 14 sends instruction, give drive circuit 13, make it to connect the power supply of electromagnet 12, electromagnet 12 energising adhesives this moment, the movable core return, driving locking lever 7 is unlocked, spool 6 is under the effect of spring 5, fall after rise, make advancing of valve, backwater closure tube 8 is connected, close and make the intake pipe 3 of heating installation and return pipe advance 4, thereby make valve closing, above-mentioned is valve and the working procedure of smart card 14 in a heating phase, smart card 14 lost efficacy, and needed can reuse in the next heating phase after special device resets.

If because some special requirement, or because accidental cause, when in the heating phase smart card 14 being pulled up, system can connect the power supply of electromagnet 12 automatically, makes valve closing, and smart card lost efficacy in this heating phase simultaneously.

During heating operation, smart card can detect the supply voltage of electromagnet 12 at any time, if when detected voltage is lower than required work threshold values, smart card 14 can be connected the power supply of electromagnet 12, makes valve closing.

The group of mounting type of the present utility model and radiator is identical to mode, its installation dimension is identical with the installation dimension that " big 60 ", " M132 " reach model radiators such as " four posts 813 ", 19 is that intelligent card type heat supply control valve group is to mode profile schematic representation among Fig. 4,18 is radiator, and 17 is detection components.
