Abstract

The utility model discloses a reflux controller arranged on a drink filling valve. The utility model comprises an upper valve body and a lower valve body which are sealed to connect as integration, wherein, a float is arranged inside a hollow cavity. A joint pipeline is arranged on the upper valve body, and a control device which gives loose to and limits the float to float upwards is also arranged on the upper valve body. After a bottle opening is filled, air return (reflux) enters an upper and a lower chambers which are composed of the upper and the lower valve bodies via a joint pipe. The float floats upwards, an air return (reflux) passage automatically closes. Only a little drink leaks, and thereby, the aim for controlling reflux can be achieved. The reduction of drink quality and the energy waste, which are caused by repeated heating, can be avoided.

Description

The backflow controller

The utility model relates to beverage filling machinery, specifically is a kind of auxiliary device that is installed on the beverage filling valve, is used for beverage backflow control.

Be used for the gravity type boat davit bottle placer of beverages such as tea, fruit juice, packing container is plastic bottle or glass bottle, profusely can, and the can temperature does not need re-pasteurization more than 85 ℃ after the can, so that cut down the consumption of energy and guarantee the local flavor of drink.Usually this class filling valve should have following performance: guarantee profusely can 1.; 2. when can temperature is not enough, automatic return flow line should be arranged; 3. double as original position in return flow line is cleaned (CIP) passage.So this type of filling valve design usually has a feed pathway and a return-air (backflow) passage, during normal can, return-air is used to discharge the gas in the bottle, after filling, in the next beverage process bottle of feed pathway, flow out from the return flow line, arrive the backflow storage tank, beat away by pump again and pass through ultra high temperature sterilization again, enter the bottle placer can again.So just bring a very serious problem, through the beverage of sterilization have near half enter the backflow cylinder, and mechanical separator speed is slow more, quantity of reflux is big more, need return sterilization again, cause very large energy dissipation, simultaneously, heating can influence the quality of beverage repeatedly, such as, tea through repeatedly the heating after, color can become chocolate, can occur simultaneously the precipitation.

The purpose of this utility model provides the backflow controller on a kind of return-air (backflow) passage that is attached to filling valve, effectively controls the quantity of reflux after beverage is filled bottle, and the frequency that reduces heating repeatedly is to guarantee the quality of beverage.

For achieving the above object, the technical solution adopted in the utility model is: upper valve body and following valve seal formula are connected as a single entity, be provided with a float in its inner cavity that forms, upper valve body is provided with the joint pipeline that is communicated with above-mentioned chamber, the diameter of float is greater than the aperture of joint pipeline, upper valve body is provided with one and lets alone and the control setup of restriction float come-up, and following valve body is provided with the connection pipe that is communicated with above-mentioned chamber.

As shown from the above technical solution, following valve body is provided with the connection pipe that is communicated with its lower chambers, connection pipe is communicated with filling valve, after bottleneck was filled, return-air (backflow) entered the chamber that is made of upper valve body and following valve body through connection pipe, and float floats and with return-air (backflow) passage SELF CL, has only a spot of leakage beverage, thereby reach the purpose that control refluxes, avoided heating repeatedly the reduction of the beverage quality that causes, also help energy savings in addition.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the birds-eye view of Fig. 1.

Below in conjunction with drawings and Examples the utility model is further described.

Embodiment

Referring to Fig. 1; 2; upper valve body 10 and following valve body 20 sealed types are connected as a single entity; promptly guarantee the sealing of binding site therebetween by seal ring; be provided with in its internal cavity this chamber is divided into; lower chambers 11; 21 two-part dividing plates 30; offer on the dividing plate 30 last; lower chambers 11; 21 holes 31 that are communicated with; be provided with a float 40 in the upper chamber 11; float 40 is baton rounds made from polypropylene; upper valve body 10 is provided with the joint pipeline 12 that is communicated with above-mentioned upper chamber 11; the diameter of float 40 is greater than the aperture of upper chamber 11 with joint pipeline 12 junctions; upper valve body 10 is provided with one and lets alone and limit the control setup 50 that float 40 floats; the effect of control setup 50 mainly is to allow that float 40 can freely be floated by buoyancy when guaranteeing normal the use; simultaneously can satisfy again where necessary that float 40 buoyance lifts are restricted, guarantee the unimpeded of current return circuit.Following valve body 20 is provided with the connection pipe 60 that is communicated with its lower chambers 21, and connection pipe 60 is in order to the connection with the filling valve refluxing opening.

Control setup 50 comprises a control stalk (53), and the one end links to each other with the end of the piston rod (52) of cylinder (51), and shaft is positioned on the upper valve body (10), and its front end extends in the upper chamber (11) and can be in the top that is positioned at the float (40) when the next.

Control stalk 53 and the piston rod (52) of cylinder 51 are coaxial fixing and be in horizontal direction, upper and lower chamber 11,21 is the taper type chamber, dividing plate 30 is the V-arrangement of upward opening in the cross section of vertical guide direction, this kind dividing plate 30 can make full use of the space in the upper and lower chamber 11,21, help dwindling the volume of upper and

lower valve body

10,20, cylinder 51 is fixed on the sidepiece of upper valve body 10 by support 70.

What the two-dot chain line in the accompanying drawing was illustrated is filling valve, the utility model is fixed on the filling valve, cylinder 51 is failure to actuate during normal can, the control stalk 53 that links to each other with piston rod 52 is Su Huizhuan, gas in the bottle passes through the connection pipe 60 of this controller successively, on, lower chambers 11,21, dividing plate 30 and joint pipeline 12 are discharged, after filling, beverage refluxes current return circuit is blocked in float 40 picking-ups, be that float 40 is subjected to beverage buoyancy and is held up and upper chamber 11 is blocked with the path of joint pipeline 12 junctions, significantly reduce quantity of reflux, significantly reduced the energy and equipment waste that the backflow beverage causes because of heating simultaneously; Certainly, as when finding that the not enough or system of hot beverage temperature need clean, by control cylinder 51 actions, control stalk 53 stretches into upper cavity 11 immediately and blocks float 40, make it can not rise, thereby limit it and stop up refluxing opening, guarantee that promptly upper chamber 11 is unimpeded with the path of joint pipeline 12 junctions, beverage or cleaning liquid can pass through smoothly.
