Description
The utility model discloses a kind of gas-liquid mixing pump, be installed in the refrigeration system of ice cream freezing machine, play effect air and the mixing of liquid material.
Existing gas-liquid mixing pump, be that the air-inlet cavity that the air compression system that will be made of one-way valve, modulating valve etc. is connected in the pump housing is realized air in certain amount is sent in the cylinder that congeals, or save a cover air compression system and directly air is sent in the cylinder that congeals.Though the former can realize controlling ice-cream expansivity by regulating air mass flow, shortcoming is that equipment investment is big, complex structure, volume increase; The latter's shortcoming is to control the air quantity of sending in the liquid material, influences ice-cream expansion effect.
Task of the present utility model is will provide a kind of and need not a cover air compression system, can control and send in the ice cream liquid material the necessarily gas-liquid mixing pump of air quantity.
Task of the present utility model is finished like this, a kind of gas-liquid mixing pump, it includes the pump housing four-way 7 that is made of charging and discharging cavity 33,34 and air inlet cavity 35 and piston cavity 36 that is installed on the support 12, be located in the piston cavity 36 and reached by seal ring 10 breather cheek valve 1 of the piston 8 that matches with piston cavity 36 gaps and power transmission mechanism that is connected with the end of piston 8, connection on air inlet cavity 35.
Below in conjunction with accompanying drawing the utility model is further described below.
Fig. 1 is the utility model general assembly structural drawing.
Fig. 2 is the sectional view of breather cheek valve 1 of the present utility model.
Fig. 3 is the A-A profile stretch-out view of Fig. 1.
Fig. 4 is unidirectional discharge valve sectional view.
Breather cheek valve 1 of the present utility model by the valve body 37 of swivel nut 24, central zone arbor hole, be located at the inlet hole that communicates with arbor hole 38 on the valve body 37, adjusting nut 19, axle 17, spring 18 etc. and form, valve body 37 is connected with swivel nut 24, swivel nut 24 is connected with the air inlet cavity 35 of pump housing four-way 7, adjusting nut 19 is connected in an end of valve body 37, axle 17 is located in the arbor hole of valve body 37, the one end stretches in the swivel nut cavity 25 through arbor hole, the other end is connected with spring 18 ends, and the other end of spring 20 is pressed on the adjusting nut 19 that is connected on the valve body 37.An end end of stretching into the axle 17 in the swivel nut cavity 25 of the present utility model is shaped on a cone 21, is provided with seal ring 23 between cone 21 and the valve body 37.Inlet hole 38 is located on the middle part convex shoulder 28 of valve body 37, and adjusting nut 19 is threaded with an end of valve body 37.One end of axle 17 is located in the arbor hole on the valve body 37, and its end is stretched in the swivel nut cavity 25, then valve body 37 is threaded with swivel nut 24, cooperate closely, avoid leaking, when connecting, add seal ring 22 in order to make the two.When valve body 37 with after swivel nut 24 is connected, swivel nut 24 is connected in the accent of the air inlet cavity 35 of pump housing four-way 7 by nut 3, be tightly connected for the two reaches, when connecting, embed seal rings 2 at air inlet cavity 35 again.One end end of the axle 17 of band cone 21 is positioned at swivel nut cavity 25, the other end end of axle 17 has a hole 26, one end of spring 18 is set in it, and the other end of spring 18 is pressed on the convex shoulder 27 of being located at the adjusting nut 19 that is threaded with valve body 37 works on the valve body 37.When adjusting nut 19 to the right (promptly inside) when revolving, spring 18 just extend, and the opening force of axle 17 is diminished, the air quantity that is entered by inlet hole 38 increases, and enters the air quantity increase in the liquid material thereupon, ice cream overrule just improves; Otherwise, when adjusting nut 19 (promptly outside) when revolving left, spring 18 just compresses, it is big that the opening force of axle 17 becomes, at this moment being located at seal ring 23 on the cone 21 that stretches into axle 17 1 ends in the swivel nut cavity 25 and the open gap between the inlet hole 38 diminishes, the air inlet just reduces, and the air quantity that thereupon enters in the liquid material reduces, and ice cream overrule just reduces.In addition, the loosening voluntarily air inflow that influence occurs for avoiding adjusting nut 19, supportting between the middle part convex shoulder 28 of the convex shoulder 27 of adjusting nut 19 and valve body 37 has spring 20.At ordinary times, axle 17 makes ambient air and swivel nut cavity 25 isolated by seal ring 23 under the effect of piston 8, does not make air enter swivel nut cavity 25 and sneaks in the ice cream liquid material.When work, owing to the piston 8 descending low pressure that produce, under the effect of atmospheric pressure, axle 17 overcomes the effect of spring 18 and moves to right, guarantee air inlet gap between inlet hole 38 and the swivel nut cavity 25 by seal ring 23, make air enter swivel nut cavity 25 and sneak in the ice cream liquid material by the inlet hole on the valve body 37 38.The charging cavity 33 of pump housing four-way 7 is connected with ice cream liquid material conveying tube, and adds seal ring 9 and sealed.At the accent of discharging cavity 34 by nut 5 and add seal ring 6 and be connected with a unidirectional discharge valve 4.Whole gas-liquid mixing pump is installed on the support 12 by nut 11.
Seal ring 10 of the present utility model has twice.When packing into an end of piston 8 in the piston cavity 36, two seals circle 10 is placed between piston 8 and the piston cavity 36.Thereby can fully guarantee both sealing effects, unlikely leakage.The effect of piston 8 is batch mixing and feeding.The other end of piston 8 is connected with an end of connecting rod 14 by pin 13, the other end of connecting rod 14 is installed on the eccentric shaft 29, eccentric shaft 29 is installed on the eccentric disc 16, eccentric disc 16 is installed on the input shaft 15, transmission is added with bearing 30 freely between connecting rod 14 and the eccentric shaft 29 between connecting rod 14 and eccentric shaft 29 in order to make.Because what connecting rod 14, eccentric shaft 29, eccentric disc 16, input shaft 15 were formed is a power transmission mechanism, so, during work, when power is imported by input shaft 15, make eccentric disc 16 rotations, thereby make piston 8 do upper and lower to-and-fro motion by the connecting rod that eccentric shaft 29, connecting rod 14 and eccentric disc 16 constitute.When piston 8 down moves, discharging cavity 34 is in closed condition, thereby make and produce low pressure in the discharging cavity 34, under the effect of atmospheric pressure, air is pressed in the axle 17 of breather cheek valve 1 and the inlet hole 38 on the valve body 37, air is pressed in the air inlet cavity 35 of pump housing four-way 7 thereby back down spring 18; Meanwhile, atmospheric pressure sprays into the liquid material inner chamber of pump housing four-way 7 from the accent of charging cavity 33, so far air mixes in same chamber with the liquid material, and then piston 8 moves upward, and when piston 8 moves upward, seals air inlet cavity 35 and charging cavity 33 by piston 8, the pump internal pressure is improved, back down sealed steel ball 32 until the active force that is enough to overcome the spring 31 that is contained on the discharge valve 4, open discharge valve 4, the ice cream material of entrained air is sprayed in the conveyance conduit through discharge valve 4.
The utility model overlaps air compression system thereby saved one, and can control the air quantity of sending in the ice cream liquid material owing to the accent at air inlet cavity 35 has connected breather cheek valve 1; Owing to used two seals circle 10,, the blowdown phenomenon can not occur so can fully guarantee the sealing between piston 6 and the piston cavity 36.
