Description
Technical field
The present invention relates to a kind of proportioning mixer, relate in particular to a kind of proportioning mixer that the fire-fighting foams suppression system is carried out the step-less adjustment proportions of ingredients in can be between the setting district that is used for.
Background technique
In the fire-fighting foams suppression system, need automatic by a certain percentage mixing water and two kinds of liquid of foam solution, the desired range of working pressure broad of system, under the metastable situation of pressure (generally being the relative pressure of regulating and control by equilibrium valve before two media is entering proportioning mixer), be that the flow area by the two media that enters proportioning mixer is determined.Common employed proportioning mixer is a stationary structure, MEDIA FLOW is a definite value through the flow area of orifice plate, want to change the orifice plate that proportions of ingredients just must be changed different flow areas, the outlet end of proportioning mixer has a necking section, this is typical Venturi tube feature, and the discharge coefficient of Venturi tube is to keep good linearty at the reynolds number range of broad; Moreover the foam solution tube inlet is arranged perpendicular to fire-prevention pipe, penetrate under the effect of inhaling effect at venturi, under the ordering about of foam pump pressure, traditional proportioning mixer is owing to be subjected to the limitation of its structure, when system pressure changes, proportions of ingredients can fluctuate thereupon, is difficult to find desirable operating point and keeps more stable working state.And the work of changing orifice plate is very loaded down with trivial details, and labor intensity is big again, so make troubles for installation and debugging.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of easy to operate, labor intensity is little, using effect is good regulation type proportional mixer.
In order to solve the problems of the technologies described above, the present invention is achieved through the following technical solutions;
The present invention includes runner pipe, described runner pipe is provided with outer sleeve outward, be provided with cavity between described runner pipe and the outer sleeve, described outer sleeve is provided with the foam solution pipe, described foam solution pipe is connected with cavity, described runner pipe and outer sleeve one end are provided with shrouding, described shrouding is with the ring-shaped cavity sealing of runner pipe and the formation of outer sleeve end, the described runner pipe and the outer sleeve the other end are provided with orifice plate, described orifice plate is provided with several holes, hole on the described orifice plate and runner pipe are communicated with the ring-shaped cavity that outer sleeve forms, described orifice plate one side flexible connection regulating ring, described regulating ring be provided with orifice plate on the corresponding hole of hole number.
As preferably, also be provided with controlling device on the described regulating ring, described controlling device comprises the fixed base that is arranged on the outer sleeve, be arranged at trim ring seat in the fixed base, be arranged at trim ring in the trim ring seat and the eccentric shaft in the middle of the trim ring, described eccentric shaft end and regulating ring flexible connection.
The present invention compares with existing technology, has following several respects beneficial effect:
1, easy to operate.The present invention adopts orifice plate and regulating ring combined, by regulating the hole and the degree of misalignment in the hole on the orifice plate on the regulating ring, changes the size of flow area, can be in the interval of setting the step-less adjustment proportions of ingredients, find optimal working point easily.
2, labor intensity is little.The present invention has removed the frequent dismounting and change orifice plate in the system debug process from.
3, using effect is good.Because the present invention can realize the step-less adjustment proportions of ingredients, thereby finds optimal working point easily; Simultaneously, adjusted the direction that inner shape chamber and foam solution go into to annotate mix, improved when system pressure produces fluctuation the influence to proportions of ingredients, thereby the proportions of ingredients trend is stablized, the mixed solution quality effectively improves.
4, cut down expenses.Because easy to operate, labor intensity is little, using effect is good, so can reduce the time and the corresponding cost of installation and maintenance greatly.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
Embodiment
The present invention is described in further detail below in conjunction with the drawings and the specific embodiments:
As shown in drawings: the present invention includes runner pipe 1, the runner pipe 1 outer outer sleeve 2 that is provided with, be provided with cavity 3 between runner pipe 1 and the outer sleeve 2, outer sleeve 2 is provided with foam solution pipe 4, foam solution pipe 4 is connected with cavity 3, runner pipe 1 is provided with shrouding 5 with outer sleeve 2 one ends, the ring-shaped cavity sealing that shrouding 5 forms runner pipe 1 and outer sleeve 2 ends, runner pipe 1 is provided with orifice plate 6 with outer sleeve 2 the other ends, orifice plate 6 is provided with several holes, hole on the orifice plate 6 and runner pipe 1 are connected with the ring-shaped cavity that outer sleeve 2 forms, and orifice plate 6 one sides flexibly connect regulating ring 7, regulating ring 7 be provided with connecting groove and with orifice plate 6 on the corresponding hole of hole number; Also be provided with controlling device on the regulating ring 7, controlling device comprises the fixed base 8 that is arranged on the outer sleeve 2, be arranged at trim ring seat 9 in the fixed base 8, be arranged at trim ring 10 in the trim ring seat 9 and the eccentric shaft 11 in the middle of the trim ring 10, and eccentric shaft 11 ends are stretched in the groove of regulating ring 7 and its flexible connection.
The present invention is tightly connected shrouding 5 ends and inlet tube 20 in use, and orifice plate 6 ends and outer pipe 21 are tightly connected.When regulating proportions of ingredients, aperture maximum when regulating ring 7 and orifice plate 6 pairing holes are overlapping by eccentric shaft 11 rotatable regulating rings 7, misplaces the regulating ring 7 and the hole of orifice plate 6, thereby changes the aperture size, to reach the purpose of adjusting the mixed solution ratio.
