Abstract
The utility model relates to a rotor-type closed gas regulating valve which is composed of a valve casing, and an air inlet and an air escaping valve outlet thereof, and a rotor-type electromagnet which is not provided with a stop iron and is installed at the lateral part of the valve casing, wherein the position of the extension end of a rotary shaft of a rotor-type armature of the electromagnet, which corresponds to the air escaping valve outlet is provided with a valve sheet; thus, the air escaping valve outlet is adjusted to be opened or closed and is adjusted continuously. Compared with the prior art, the utility model has the advantages of large initial suction force, little power consumption, large flow, long run length, reliable opening and closing, convenient adjustment, etc.
Description
The utility model relates to the gas control valve technical field, but particularly a kind of rotator type confining gas modulating valve that is used for the control gaseous flow.
Existing gas control valve is to adopt no buting iron solenoid electromagnet structure, and its pull characteristics are more smooth, and suction is less, and power consumption is big, and sealing that generally can not the double as gas pipeline is referring to characteristic curve shown in Figure 1.And another kind of employing mountain font clapper-type electromagnetic iron construction, its pull characteristics are very steep, when adhesive asks that the crack is strengthened, its suction decay is very fast, this solenoid valve can not go to realize the linearly adjust of tolerance by the continuous control magnitude of current, and can only make electromagnet be in the open and close state by to coil input square-wave current, recently change the open and close time scale of electromagnet by the duty that changes electric current, thereby reach the purpose of regulating tolerance.This mode switching regulator, gas can produce pulsation in adjustment process, and consequent problem is an electromagnet because frequent mechanical vibration cause the wearing and tearing of modulating valve easily, and the eigentone of electromagnet must be lower than its input current frequency.During as this solenoid valve double as sealing, suction minimum owing to electromagnet this moment, when overcoming sealing spring force, pressurized gas and execute the viscous force of the power of dryvalve sheet and valve port and valve block rubber as need, the very contradiction that just seems, when requiring bigger gas output, the diameter of valve port and rubber valve plate needs to strengthen, armature travel needs lengthening, and the power consumption of electromagnet, weight, volume will greatly strengthen, at this moment, electromagnet might because of its eigentone is too low can't proper functioning.
But the purpose of this utility model is to provide a kind of rotator type confining gas modulating valve that not only can seal but also can regulate continuously, and not only power consumption is little, flow is big, stroke is long for it, open and close is reliable, and can realize the controllable continuous of gas is regulated.
But the purpose of this utility model is achieved in that a kind of rotator type confining gas modulating valve, comprises valve casing and the set suction port and the valve port of giving vent to anger, and is used for the electromagnet assembly of control gaseous flow, installs at the valve casing sidepiece to have or not buting iron rotator type electromagnet; The rotator type armature shaft epitaxial end of this electromagnet is fastened with the valve block support with the valve port corresponding section of giving vent to anger, and on this valve block support valve block is housed; In the bearing shell positioning hole on valve casing rubber seal is housed.Described rotator type electromagnet is equipped with Returnning spring, and the one end is fixed on iron core or the support, the other end be contained in rotator type armature one side or armature shaft extension part on the fastening armed lever.This Returnning spring one end is provided with adjusting screw, is used to revise the systematic error that various factors causes.Under the cold situation of rotator type electromagnet, because the effect of Returnning spring makes the gas outlet valve mouth be in closed state, thereby plays sealing process.During energising work, by changing its coil current size, the just can regulate gas flow of valve port of giving vent to anger.
No buting iron rotator type electromagnet is made up of iron core, coil, rotator type armature, rotator type armature is bearing on the support that is anchored on iron core by rotating shaft and bearing, this armature both sides end face has equidistant gap with corresponding core side mask, thereby, have the big characteristics of smooth, the initial suction of pull characteristics, can change coil current easily, regulate the adhesive stroke and carry out approaching linear continuous adjusting, referring to curve shown in Figure 2, but this electromagnet is applicable to manufacturing confining gas modulating valve.
The utility model is owing to utilized the big characteristics of the initial suction of rotator type electromagnet, thereby just can remove to overcome the seal force of Returnning spring, pressure and rubber valve plate that pressurized gas imposes on rubber valve plate and the adhesive force of the valve port of giving vent to anger with enough big suction in its action starting point, if will strengthen the length that actuating length only needs the iron core both sides concave arc surface of elongated rotor armature both sides convex globoidal and correspondence, and need not to strengthen the electromagnet power consumption therefore, can strengthen the valve block stroke easily.
Obviously, the utility model has compared with prior art had that suction is big, power consumption is little, flow is big, stroke is long and open and close is reliable and be convenient to advantage such as adjusting.
Fig. 1 is the existing pull characteristics plotted curve that adopts no buting iron solenoid electromagnet, and F is a suction among the figure, and δ is an armature travel, and the adhesive terminal point is 0.
Fig. 2 is the pull characteristics plotted curve of no buting iron rotator type electromagnet, and F is a suction among the figure, and δ is the stroke of armature, and the adhesive terminal point is 0.
Fig. 3 is an embodiment's of the utility model a structural representation.
Fig. 4 is the right elevation after Fig. 2 removes valve casing.
By following embodiment the utility model is further elaborated.
Referring to Fig. 3 and shown in Figure 4, but present embodiment rotator type confining gas modulating valve is made up of valve casing 1 and the no buting iron rotator type electromagnet that is installed on valve casing 1 one sides.Valve casing 1 inner chamber is provided with suction port and the valve port 2 of giving vent to anger, on valve casing 1 one side planes, have the positioning hole of armature shaft bearing shell 8, the shaft bearing shell 8 of electromagnet and rotating shaft 12 extension parts in this, and are equipped with rubber seal 11 with regard to installing and locating in the rotating shaft 12 in this positioning hole.No buting iron rotator type electromagnet is packed on valve casing 1 one side planes by its iron core 7 and support 6.Be provided with Returnning spring 9 between its rotator type armature 13 and the support 6, on this Returnning spring 9, adjusting screw 10 be housed also.Be fastened with valve block support 4 at rotating shaft 12 epitaxial ends and valve port 2 opposite positions of giving vent to anger, and on valve block support 4, valve block 3 be housed.After coil 5 energisings, but the rotator type confining gas modulating valve of said structure can be realized the gas output of the valve port 2 of giving vent to anger is sealed or regulated continuously.
