The present invention relates to an intelligent electric valve with a porcelain core, which belongs to the field of fluid conveying and particularly to the technical field of fire-fighting devices. The intelligent electric valve of the present invention is composed of a valve body, a valve core, a valve seat, a touch block ring, a limit switch, a step motor, a shaft connector, an electronic circuit board, a housing, etc. The present invention is characterized in that the valve core is made of porcelain and has the characteristics of high temperature resistance, low temperature resistance and corrosion resistance. A circuit is controlled by a monolithic computer and has the functions of automatic error detection, automatic error correction and automatic repair report, which is favorable to centralized type networked management, and the automatization can be realized. The intelligent electric valve with a porcelain core can be matched with an automatic extinguisher as well as can be used for fluid conveying systems of other fields such as petroleum, chemical industry, etc.
Description
Technical field the invention belongs to the FLUID TRANSPORTATION technical field, and particularly the fire-fighting equipment technical field relates to a kind of high temperature resistant, low temperature resistant, corrosion resistant intelligent porcelain core valve with electrically motorized operation that has.
The electromagnetically operated valve that background technology is used in the market is many, and the small-bore pipe roadbed that especially adopts in fire protection equipment originally all uses electromagnetically operated valve.In the electromagnetically operated valve design commonly used, there is a high pressure blasthole water inlet, and diameter is 1.O～1.5mm, allows to be full of water in the rubber diaphragm epicoele consistent with inlet opening pressure to keep-up pressure, and makes rubber membrane keep good sealing at the valve port place.When coil electricity, electromagnetic actuation is opened spilled water hole, because the spilled water hole aperture is about 10 times of the inlet opening, the pressure of rubber diaphragm epicoele is descended, open valve under the effect of working medium pressure rapidly.Because water quality is relatively poor, especially in the north, has a large amount of incrustation scales in pipe network, even new pipe network also because of problems such as installation and water quality, causes electromagnetically operated valve to block.By installing filter screen additional in the valve inlet opening, can avoid blocking, but can cause the hydraulic pressure deficiency, make fire-fighting equipment be difficult to reach desired index.
Electrical ball valve appearred in recent years, because of ball valve turnover bore is bigger, can solve the obstructing problem that electromagnetically operated valve exists, but because of the ball valve contact-making surface bigger, add and adopt the polytetrafluoroethylene ring sealing, for guaranteeing good sealing, certain pressure must be arranged, cause frictional force to increase, bring higher blocking-up moment to motor, when design, must use the motor of higher-wattage, cause the cost of product too high, be difficult to be accepted by market.By the repacking ball valve, reduce seal pressure, optionally like this reduce cost, but its price compares with electromagnetically operated valve and still exceeds about several times with the slightly little motor of power, also be difficult to use in batches.
Summary of the invention the purpose of this invention is to provide a kind of inexpensive, have high-strength, high temperature resistant, low temperature resistant, corrosion-resistant, frictional force is little, and can automatic error detection, error correction, report the intelligent porcelain core valve with electrically motorized operation of function for repairment.
Technical solution of the present invention is, a kind of intelligent porcelain core valve with electrically motorized operation, be made up of valve body 6, spool 1, valve seat 5, stepping motor 9, electronic circuit board 13, collision block ring 11, limit switch 10, shaft joint 7 and outer cover 14, stepping motor 9 rotates, and connects spool 1 by shaft joint 7, driving collision block ring 11 simultaneously rotates, collision block ring 11 is run into limit switch 10, and signal is beamed back single-chip microcomputer, finishes maintenance ON state, valve-off, automatic error detection, reports function for repairment, it is special is made by pottery at, spool 1.
Valve body 6 is made by non-ferrous metal.
Motor rotation, rotating, spacing, locate and reset by limit switch 10 and the dual control of single-chip microcomputer pulse step number.
When single-chip microcomputer is received valve opening signal, drive stepping motor 9 is rotated, and runs into limit switch 10 when collision block ring 11, and signal is sent single-chip microcomputer back to, and stepping motor 9 stops operating.
Stepping motor 9 rotates and fails to run into limit switch 10, treat that umber of pulse is covered after, single-chip microcomputer is sent signal back to master-control room, shows that this valve work is undesired, plays and reports function for repairment.
Stepping motor 9 rotates normally runs into limit switch 10, and stepping motor 10 stops and being in wait state.When valve opening signal is cancelled, open the valve program of closing at once, stepping motor 9 counter-rotatings, process is as mentioned above.
The rotating of stepping motor 9, spacing, locate, reset etc. by limit switch and the dual control of single-chip microcomputer pulse step number; In case there is valve work undesired, start error-detecting routine signal is sent, reach the function of in time reporting for repairment; Set various self-checking functions simultaneously, as the different period self checks of year, month, day, guarantee the serviceability rate of equipment work, this fire control facility is particularly important.
Advantage of the present invention and good effect are: this valve with electrically motorized operation, the spool that adopts is by ceramic making, the inner spool pottery processes by special, reaches good seal request through fine gtinding again, has characteristics such as high-strength, high temperature resistant, low temperature resistant, corrosion-resistant, that frictional force is little.Circuit is had automatic error detection, error correction, is reported for repairment function by Single-chip Controlling, is beneficial to the centralized network management, realizes automation.
The present invention is further illustrated below in conjunction with the accompanying drawing embodiment for description of drawings.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a circuit block diagram of the present invention.
Wherein, 1. spool, 5. valve seat, 6. valve body, 7. shaft joint, 9. stepping motor, 10. limit switch, 11. collision block rings, 13. electronic circuit boards, 14. outer covers.
A kind of intelligent porcelain core valve with electrically motorized operation of embodiment is made up of valve body 6, ceramic cartridge 1, valve seat 5, stepping motor 9, electronic circuit board 13, collision block ring 11, limit switch 10, shaft joint 7 and outer cover 14.
Single-chip microcomputer is received the valve opening signal that master-control room sends, and drive motors 9 rotates and drives ceramic cartridge 1 by shaft joint 7, drives collision block ring 11 simultaneously and rotates, and the collision block ring is to limit switch 10, and signal is beamed back single-chip microcomputer, and motor stops operating.
If motor 9 rotates and fails to run into stop limit switch 10, treat that umber of pulse covers the back single-chip microcomputer signal is sent back to master-control room, show that this valve work is undesired, play and report function for repairment; As normally running into stop limit switch 10, motor stops operating, and is in to stop wait state; When valve opening signal is cancelled, open the valve program of closing, motor 9 counter-rotatings at once.
