Description

Electromagnetic combined valve

The utility model relates to a kind of fluid (for example gas or liquid) pipeline valve; The actuator that particularly relates to valve.

At present common valve has two kinds of manually operated valve and solenoid valves.Usually in industrial departments such as electric power, chemical industry, metallurgy, papermaking, machinery, light industry and civilian low-pressure fluid pipe-line system, when realizing that automatic control and safety guarantee adopt solenoid valve, manually operated valve must be set simultaneously.The executive component of difference in functionality is brought into play in both formation separately independently, respectively.This situation, no matter which kind of position solenoid valve is loaded on, There is no exception to.For example: as the solenoid valve of terminal control, its front end must be connected with manually operated valve; And, where necessary,, also must install manually operated valve additional for isolation solenoid valve as the solenoid valve of top or intermediate portion, perhaps install by-pass valve simultaneously additional for the normal operation that guarantees system.The mode of this two valves and usefulness must increase engineering cost, also brings the complexity of project installation and the inconvenience in the use simultaneously.Particularly with solenoid valve as before the table of old gas pipe line during valve because the flowmeter and the distance between the main pipe of old pipeline are limited, thereby increased the difficulty in the repacking work.

The purpose of this utility model is in order to overcome above-mentioned difficulty, a kind of electromagnetism combination brake switch and proporting that has manually-operable and two kinds of actuators of eletromagnetic-operating simultaneously to be provided.

Main points of the present utility model are to improve the internal structure of manually operated valve and solenoid valve, and take corresponding measure that the two is connected into an integral body.

Accompanying drawing is a structural representation of the present utility model.

Now, as follows with reference to description of drawings with the working principle of composite structure of the present utility model and actuator thereof:

1, the structure with manually operated valve changes the angle general formula into by straight-through type.Promptly, orthogonal and an interpenetrate duct is arranged in the axial centre and the lateral middle of spool 16.The medium that enters valve body 1 can circulate along this dihedral duct, thereby provides precondition for realizing with connecting of solenoid valve.

2, in the lower end that spool 16 combines with valve body, install seal ring 15 and locking device 13,14 additional, this had both improved the leakproofness of valve, had strengthened manually operated flexibility and reliability again.Rely on this device, spool is 90 ° rotation in valve body, gets final product the function that fluid medium is implemented break-make.

3, electromagnetic valve device is at the upper wall of valve body 1, and is in a central position with spool 16.At the upper wall of valve body 1, be positioned at the top of spool 16, a glued membrane seal valve 2 is arranged.The section configuration of seal valve is shown in 2 among the figure, and the upper wall of its underpart and valve body 1 forms a cavity around the spool upper end.Seal valve had both possessed the effect of valve, was again to isolate the seal element that valve rod 8 does not contact with medium.Under normal circumstances, cavity is normally open.The medium of valve body suction side can enter cavity through the dihedral duct of spool.

4, at the upper wall of valve body 1, be positioned at the cavity of seal valve 2 bottoms and the root on the close spool top of valve outlet one side, there is one to connect the duct.By the medium of valve body 1 in the spool duct enters the seal valve lower cavity, can enter outlet one side of valve body 1 along this passage.

5,, an insulation crimping piece 3 that has center hole is arranged on the top of seal valve 2.The effect of crimping piece can be sealed to an integral body with seal valve 2 and valve body 1, it is again the mounting base of electromagnet, (fixed core 5 being fixed on the top of insulation crimping piece 3 by fastening screw 4) especially between solenoid valve and the manual valve body, and and fluid line between the secondary insulator.The center hole of insulation crimping piece 3 is the valve rods 8 in order to pass solenoid valve.

6, the top of seal valve 2 is with mutual chimeric being integral (as shown in drawings) in the lower end of valve rod 8.If when sending electricity to the coil 6 of solenoid valve because of the needs of automatically control; Perhaps because sensing device sends instruction when making the coil of wire 6 energisings because of dielectric leakage or other abnormal conditions, and moving iron core 7 promptly is attracted, and drives seal valves 2 by valve rod 8 and closes the opening of spool 16 upper ends, medium is cut off then.

7,

spring

9,11 pairs of moving iron cores 7 of nut and the valve rod 8 existing effects that are connected, fix and reset have the effect of regulating moving iron core stroke again.Outer cover 12 have support external cabling and keep a public place clean, effects such as heat radiation, decoration.

The utility model can be designed to a plurality of series product according to caliber, valve size and medium operating mode, and selects direct current 9V, 12V, 24V, 48V respectively for use.In case of necessity, can select the above power supply of interchange or direct current 110V for use.

The utility model is to integrate manually operated valve and solenoid valve, and it is small and exquisite to have external form, novel structure, and Each performs its own functions, easy to operate, and reliable performance does not influence advantages such as flow.Industry or civilian low pressure pipeline system applicable to various flowing mediums such as water, oil, coal gas, steam.In case solenoid valve breaks down when needing maintenance, on the one hand available manually operated valve cuts off medium, realizes safety inspection or changes element; Can after cut off the front end medium, unload manual spool and remove inner dirt on the other hand.Owing to realized multi-purpose valve, both can reduce the complexity of work, can reduce engineering cost again.Particularly, can show that more it makes full use of the superiority of the confined space to the transformation of old pipeline.With the example that transform as of the domestic gas pipeline in the whole nation, the saving cost of up to ten million valves will be very remarkable, and as for the extensive use of other industrial user and other department, its reduction effect is just more considerable

The utility model and microcomputer network can be used as the actuator of fluid network telechirics, for the automatic control of pipe-line system used; Also can combine with sensing device, the actuator as escape of liquid or other unusual condition automatic blockings becomes the fluid line safety device.
