Description

Ice cream maker constant pressure valve structural system

Technical field

This utility model is related to the technical field of ice cream maker, especially ice cream maker constant pressure valve structural system.

Background technology

It is known that ice cream is a kind of refrigerating and puffing food, the height of ice cream puffing rate determines the mouth of ice cream Sense.Make the pressure during ice cream expansion rate of ice cream is had a great impact, in order to ensure that the ice cream produced has conjunction The expansion rate of lattice, ice cream feed system carries pressure holding function.However, with manufacture of ice cream, the pressure in system can be got over Come higher, parts can be caused when pressure reaches certain value to damage or cause security incident.

Utility model content

The technical problems to be solved in the utility model is: in order to overcome the deficiencies in the prior art, provides one kind can pressure release The ice cream maker constant pressure valve structural system of energy pressurize again.

This utility model solves its technical problem the technical scheme is that ice cream maker constant pressure valve structural system, should System has positioned at tremie pipe and freezing jar constant pressure valve between the two, and described constant pressure valve includes pressure release valve body, is arranged on and lets out The check valve of pressure valve body inner upper end, pressure release valve seals being arranged in mounting groove in the middle part of pressure release valve body and being arranged on are let out Sealing circle in the mounting groove of pressure valve body lower end；Described check valve section is wedge shaped and is made up of elastomeric material, check valve The one end being connected with pressure release valve body has the discharging opening that shape is leaned on slurry pressure to act on and changed.

Further specifically, slurry flows into check valve from tremie pipe and squeezes the discharging opening of check valve and then again from letting out Exit into inside freezing jar in pressure valve body.

Further specifically, when stopping conveying slurry, there is the discharging opening of slurry extruding check valve of backflow trend Lateral surface makes the discharging opening of check valve close.

Further specifically, after the continuous conveying with slurry causes relief valve valve inner pressure constantly to become big, slurry Material is flowed out by the relief hole on pressure release valve body and backs down pressure release valve seals and flows in raw material tank.

The beneficial effects of the utility model are: this ice cream maker constant pressure valve structural system has the advantage that

First, when in feed system, pressure reaches certain value, ice-cream slurry flows out from the pressure release in the hole of constant voltage valve body, Back down pressure release valve seals, backflow of slurry, in raw material tank, plays the effect of pressure release so that the pressure in feed system is protected all the time Hold in safety range, also avoid the waste of raw material it is ensured that the normal work of machine, the service life of elongated component；

2nd, when stopping conveying slurry, the lateral surface with the slurry extruding check valve discharging opening of backflow trend makes list Close so that ice-cream slurry will not flow back because of pressure to the discharging opening of valve, not only maintain the normal work of system, also make Obtain discharge system to maintain under a constant operating pressure it is ensured that the ice cream produced has qualified expansion rate.

Specific embodiment

Presently in connection with accompanying drawing, this utility model is described in further detail.These accompanying drawings are the schematic diagram of simplification, Basic structure of the present utility model is only described in a schematic way, therefore it only shows the composition relevant with this utility model.

See Fig. 1, ice cream maker feed system has raw material tank 1, constant pressure valve 2, puffing pump 3, expanded pump motor 4, freezing jar 5 With pour out mechanism 6, expanded pump motor 4 is arranged on the afterbody of raw material tank 1, and puffing pump 3 is arranged on the outfan of expanded pump motor 4 simultaneously It is placed in the inside of raw material tank 1, freezing jar 5 is arranged on the bottom of raw material tank 1, the tremie pipe 3-1 of puffing pump 3 and entering of freezing jar 5 Expects pipe is docked by constant pressure valve 2, pours out the front portion that mechanism 6 is arranged on freezing jar 5；Expanded pump motor 4 drives puffing pump 3 to work, Suction tube on puffing pump 3 draw the slurry in raw material tank 1 and pass through on puffing pump 3 tremie pipe 3-1 and freezing jar 5 on entering Slurry is delivered in freezing jar 5 expects pipe.

See Fig. 2, ice cream maker constant pressure valve structural system, this system has positioned at tremie pipe 3-1 with freezing jar 5 between the two Constant pressure valve 2, constant pressure valve 2 includes pressure release valve body 2-3, the check valve 2-1 being arranged on pressure release valve body 2-3 inner upper end, peace The pressure release valve seals 2-2 being contained in mounting groove in the middle part of pressure release valve body 2-3 and be arranged on pressure release valve body 2-3 lower end mounting groove Interior sealing circle 2-4.Check valve 2-1 section is wedge shaped and is made up of elastomeric material, and elastomeric material can be silica gel, unidirectional One end that valve 2-1 is connected with pressure release valve body 2-3 has the discharging opening 2-1-1 that shape is leaned on slurry pressure to act on and changed.

See Fig. 3 and Fig. 4, when constant pressure valve 2 is installed, first pressure release valve seals 2-2 and sealing circle 2-4 is arranged on pressure release On valve body 2-3, then again check valve 2-1 is arranged on inside pressure release valve body 2-3.Tremie pipe 3-1 one end is inserted into constant voltage On valve 2, one end is arranged on the installation in the hole of puffing pump body 3-5 front end, is fixed by blanking pipe clip 3-4, and puffing pump is originally The tremie pipe 3-1 of body 3-5 front end installs in the hole and is also equipped with non-return piece 3-3 and sealing ring 3-2, and non-return piece 3-3 plays to be prevented from starching The effect of material backflow.

See Fig. 5, tremie pipe 3-1 has a fixing cover 3-1-1, during installation, tremie pipe 3-1 inner tube inserts check valve 2- In 1, extruding check valve 2-1 makes it be close to check valve valve body 2-3 endoporus hole wall and plays sealing function.Fixing cover 3-1-1 is enclosed within and lets out Pressure valve body 2-3 outer wall, prevents run-off the straight after its stress.

See Fig. 6, during conveying ice-cream slurry, slurry flows into check valve 2-1 from tremie pipe 3-1 and squeezes check valve 2-1's Discharging opening 2-1-1, then exits into inside freezing jar in pressure release valve body 2-3 again.

See Fig. 7, when stopping conveying slurry, because the pressure within feed system leads to slurry to have the trend of backflow, have The slurry of backflow trend extrudes the discharging opening 2-1-1 lateral surface of check valve 2-1 so that check valve 2-1 discharging opening 2-1-1 closes, Serve the effect of pressurize so that ice-cream slurry will not flow back because of pressure while preventing backflow of slurry, not only tie up Holding the normal work of system, also making discharge system maintain under a constant operating pressure ice cream it is ensured that producing There is qualified expansion rate.

See Fig. 8, with the continuous conveying of slurry, the pressure of internal system can be increasing, when internal system pressure reaches During certain value, the relief hole 2-3-1 that slurry passes through on pressure release valve body 2-3 flows out, and backs down pressure release valve seals 2-2, slurry returns Flow in raw material tank 1, play the effect of pressure release so that the pressure in feed system remains in safety range, also avoid The waste of raw material is it is ensured that the normal work of machine, the service life of elongated component.

With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, related work people Member can carry out various change and modification completely in the range of without departing from this utility model technological thought.This reality The content being not limited in description with new technical scope it is necessary to determine its technology according to right Property scope.
