Abstract
The utility model discloses a glass electromagnetic valve. A valve core capable of moving up and down is arranged at the inner part of a glass valve body and formed by sealing an iron core through polytetrafluoroethylene plastics. An iron sleeve, a wire winding shaft and a coil are arranged at the outer part of the valve body, a power controller is utilized to control the switch on/off of current of the coil to enable the iron sleeve at the outer part of the valve body to generate or lose magnetism, so that the suction and the drop of the valve core at the inner part of the valve body are realized and the control over the pass and the blockage of liquid in a flowing valve is realized. The electromagnetic valve has the advantages of corrosion resistance of chemical reagent, long service life, easy assembly and disassembly, and convenient cleaning.
Description
Technical field
The utility model relates to a kind of solenoid valve when being used for units such as scientific research, school, factories and miness, hospital, monitoring, supervision and carrying out titrimetry, particularly relate to a kind of can be by the vitreous electricity magnet valve of power controller controls rate of titration and titration end-point.
Background technique
The method that is used at present to control rate of titration and titration end-point in titrimetry instrument automatically mainly contains two kinds, and a kind of is plunger type titration control by the power controller controls stepper motor; Another kind is to be controlled by the titration of power controller controls electromagnetic valve type.The former complex structure and in use plunger tube clean inconvenience; The latter be connect at controller, solenoid valve is to the unclamping, push and realize titration control of flexible rubber hose during deenergization, and flexible rubber hose is because permanent contact chemical reagent in addition by constantly intermittently extruding, makes that it is aging easily, cracking, leakage, needs often replacing.
The model utility content
In order to overcome the deficiency of present automatic titration device, the utility model provides a kind of vitreous electricity magnet valve, and this electromagnetic valve structure is simple, easy accessibility, clean easily, can use for a long time.
The technological scheme that its technical problem that solves the utility model adopts is: at the glass valve inner spool that can move up and down is arranged, spool is to be made of through the polytetrafluoroethylplastic plastic sealing iron core.Form when the spool lower external face contacts with glass valve body lower inner surface and closely cooperate the seepage of prevention liquid.The spool outer surface of upper has three above uniform ring around the salient point that distributes, and what the maintenance spool can be vertical moves up and down.There are iron sleeve pipe, roll and coil in the valve body outside, by the connecting and disconnecting control of power-supply controller of electric to coil current, make outside ferule produce magnetic or lose magnetism, form the picking up or falling of valve inner spool, thus realized to solution in the valve of flowing through by with the control of blocking-up.
During use, the suitable for reading and burette of vitreous electricity magnet valve is connected with flexible rubber hose, the end opening of vitreous electricity magnet valve is chewed with flexible rubber hose with titration and is connected, and the wiring terminal that coil is drawn is connected with power-supply controller of electric.Titrant is housed in the burette.When power-supply controller of electric was connected, electric current fed coil, made ferule produce magnetic, and the valve body inner spool is picked up, and solenoid valve is opened, and titrant is chewed outflow by the valve body internal pore through titration, implements the titration to detected solution.When power-supply controller of electric is closed, current interruptions in the coil, ferule loses magnetism, and the valve body inner spool falls automatically, and closed electromagnetic valve has stoped the outflow of titrant, and titration stops.By power-supply controller of electric coil current is carried out control at intermittence, can realize control titrant flow and rate of titration.
Compared with prior art, the utility model has the advantages that: valve body and spool chemical-resistant reagent corrode, long service life; Solenoid valve is dismantled easily, and it is convenient to clean.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As shown in Figure 1, a spool that can move up and down 3 is equipped with in glass electromagnetic valve body 2 inside, and spool 3 is to be made of through polytetrafluoroethylplastic plastic 9 sealings iron core 8.Form when spool 3 lower external face contact with glass valve body 2 lower inner surface and closely cooperate the seepage of prevention liquid.The spool outer surface of upper has three above uniform ring around the salient point 7 that distributes, and keeps spool can do vertical moving up and down.There are iron sleeve pipe 4, roll 5 and coil 6 in valve body 2 outsides.
During use, suitable for reading 1 of vitreous electricity magnet valve is connected with flexible rubber hose with burette, the end opening of vitreous electricity magnet valve 10 is chewed with flexible rubber hose with titration and is connected, and the wiring terminal 11 that coil is drawn is connected with power-supply controller of electric.Titrant is housed in the burette.When power-supply controller of electric was connected, electric current fed coil 6, made ferule 4 produce magnetic, and valve body inner spool 3 is picked up, and solenoid valve is opened, and titrant is chewed outflow by the valve body internal pore through titration, implements the titration to detected solution.When power-supply controller of electric is closed, current interruptions in the coil 6, ferule 4 loses magnetism, and valve body 2 inner spools 3 fall automatically, and closed electromagnetic valve has stoped the outflow of titrant, and titration stops.By power-supply controller of electric coil current is carried out control at intermittence, can realize control titrant flow and rate of titration.After finishing using, valve body 2 can be taken out from iron sleeve pipe 4 and clean.
Claims (3)
1. vitreous electricity magnet valve, comprise valve body, spool, coil, it is characterized in that: between described valve body outside and the coil ferule is housed, described spool is to be made of through the polytetrafluoroethylplastic plastic sealing iron core, forms when the spool lower external face contacts with glass valve body lower inner surface to closely cooperate.
2. a kind of vitreous electricity magnet valve according to claim 1 is characterized in that: described valve body available flexible rubber hose suitable for reading is connected with burette, and end opening can be chewed with titration with flexible rubber hose and be connected.
