The utility model is characterized in that the membrane is arranged in a water feeding channel of the valve body, and one clamp end of the membrane is pressed into a shaft step of the push-pull leader to be fixed; a flat hole is arranged at the center of the bonnet for assembling the push-pull leader; threaded hole are arranged in the middle of the push-pull leader and connect the screw rod; steel balls are arranged on steps of an upper section of the screw rod and are fixed on the valve bonnet by a screw cap; one end of the screw handle is connected with the push-pull leader and the other end is connected with the switch pressing board; the micro-motor is fixed on the switch bracket; an upper limit switch and a lower limit switch are arranged on one side of the bracket; a groove is arranged at the top end of the screw and connected with a shaft of the micro-motor. The utility model has the advantages that the structure is simple; the use is convenient and safe, with a high practicability. The utility model can be used for heat supply pipelines and is suitable for various automatic measuring and controlling water use devices.
Description
Technical field: the utility model belongs to heat supply waterpipe heating installation valve, especially a kind of heating installation valve by microcomputerized control micro machine execution keying of heat supply water heating pipeline metering usefulness.
Background technology: the common heating installation valve of market sale now, open and close by manually pulling, can't use the microcomputerized control micro machine to carry out to open and close and carry out the automatic gauge heating, use dangerously, inconvenient, and cause the energy to waste greatly.
Summary of the invention:
Technical solution of the present utility model comprises by valve body, valve gap, diaphragm, push-and-pull guide rod, screw rod, steel ball, nut, micro machine support, micro machine, limit switch, switch press plate.On the intake tunnel of valve body diaphragm is housed, the pillow block rank that diaphragm has an end of bayonet socket to compress into the push-and-pull guide rod are fixed; There is a flat hole that the push-and-pull guide rod is installed in the middle of the valve gap, has screwed hole in the middle of the push-and-pull guide rod, be connected rotatable drive with the screw rod that has thread segment; At screw rod epimere step steel ball is installed, is used fixed by nut on valve gap; Screw rod is connected with micro-motor by the top fluting, push-and-pull guide rod side has screwed hole and is connected with the spiral shell handle, and the spiral shell handle other end connects switch press plate, and micro machine is fixed on the switch bracket, limit switch and lower position switch are installed in support one side, and switch bracket, valve gap are fixed on the valve body.
The utility model has the advantages that simple in structurely, safe in utilization, convenient, practical, be mainly used in heat supply heating pipeline metering paid utilization, adopt the microcomputerized control valve, reach energy-conservation purpose.Be specially adapted to various automatic gauges, control the supporting of water device automatically.
Description of drawings:
Fig. 1 is an integrally-built front view of the present utility model;
Fig. 2 is an integrally-built left view of the present utility model;
Fig. 3 is an integrally-built vertical view of the present utility model.
In Fig. 1-Fig. 3, valve body (1), diaphragm (2), valve gap (3), lower position switch (4), switch press plate (5), upper limit position switch (6), switch bracket (7), micro machine (8), screw rod (9), nut (10), steel ball (11), push-and-pull guide rod (12), spiral shell handle (13).
The specific embodiment:
Most preferred embodiment of the present utility model is such, referring to figs. 1 through shown in Figure 3, there are water inlet, delivery port in valve body (1) two ends, the water inlet of valve body (1) has intake tunnel, diaphragm (2) is housed on the intake tunnel, diaphragm (2) is made with rubber, and the pillow block rank that have an end of bayonet socket to compress into push-and-pull guide rod (12) are fixed; One flat hole is arranged in the middle of the valve gap (3), push-and-pull guide rod (12) is installed, have screwed hole in the middle of the push-and-pull guide rod (12), screw rod (9) hypomere has the screwed hole that screw thread is screwed into push-and-pull guide rod (12), rotatable drive; At screw rod (9) epimere step steel ball (11) is installed, is used nut (10) to be fixed on the valve gap (3) then; Screw rod (9) top fluting is connected with micro machine (8) axle, push-and-pull guide rod (12) side has screwed hole and is connected with spiral shell handle (13), spiral shell handle (13) other end connects switch press plate (5), micro machine (8) is fixed on the switch bracket (7), limit switch (6) and lower position switch (4) are installed in support (7) one sides, and switch bracket (7), valve gap (3) are fixed on the valve body (1).
Operation principle of the present utility model is such: under normal conditions, and valve open; In the time will closing, micro machine (8) starting under the micro computer indication promotes push-and-pull guide rod (12) by screw rod (9) and moves downward.When push-and-pull guide rod (12) when going downwards to a certain degree, by the promotion of spiral shell handle (13), by the drive of spiral shell handle (13), switch press plate (5) is run into lower position switch (4), and the micro machine of cutting off the electricity supply stops operating, simultaneously, diaphragm (2) is the intake tunnel of closed valve (1) also, realizes closing.Otherwise in the time will opening valve, micro machine (8), drives push-and-pull guide rod (12) and moves upward by the promotion of spiral shell handle (13) by screw rod (9).When push-and-pull guide rod (12) when moving upward to certain altitude, by the drive of spiral shell handle (13), switch press plate (5) is run into upper limit position switch (6), cuts off the electricity supply, and micro machine stops operating, and diaphragm (2) is also mentioned fully simultaneously, connects pipeline.
Claims (1)
