Description
Technical field
The utility model is related to a kind of filling valve with backflow mechanism.
Background technology
Traditional contactless filling valve, does not have feed back passage.When the liquid material of temperature requirement is filled with, by
In the liquid material that a part is inevitably remained in the cavity of valve seat, the temperature of the liquid material of these residuals can not
Control, can influence to finally enter the bulk temperature of the liquid material in filling bottle, i.e., this kind traditional contactless filling valve cannot
Filling temperature is controlled well.There is the liquid material of temperature requirement when not therefore being suitable for filling.
The content of the invention
The purpose of this utility model is to provide a kind of filling valve with backflow mechanism, there is temperature requirement liquid when meeting filling
The filling demand of material.
To reach above-mentioned purpose, the technical solution adopted in the utility model is：
A kind of filling valve with backflow mechanism, in frame, the filling valve include valve seat in the frame,
The backflow mechanism that the feed pipe connected with the valve seat is connected with the valve seat；The backflow mechanism includes and the valve seat
It is the reflux line of connection, described for controlling the liquid material in the valve seat whether to flow into located at described reflux line one end
Recycle control valve in reflux line.
Preferably, the valve seat is including cavity, the up and down valve element in the cavity, for driving the valve
Valve opening driver, the seal located at the valve element bottom that core is moved downward, the cavity bottom extend inwardly to form for
The seal is coordinated to seal the extension of the cavity.
It is highly preferred that the extending part is in the top of the seal.
It is highly preferred that the seal is sealing ring.
It is highly preferred that being provided with the reset for being resetted to the valve element depressed between the valve seat and the valve element
Spring.
Preferably, the filling valve also includes the flowmeter on the feed pipe.
Due to the utilization of above-mentioned technical proposal, the utility model has following advantages compared with prior art：This practicality is new
A kind of filling valve with backflow mechanism of type, by connecting backflow mechanism on the valve seat of filling valve, when not filling, material passes through back
Stream mechanism is back to specified recovery point, it is ensured that liquid material temperature is constant when filling, meets the requirement of hot-filling Process.

Specific embodiment
Come to be further elaborated the technical solution of the utility model below in conjunction with the accompanying drawings.
Referring to shown in Fig. 1-2, above-mentioned a kind of filling valve with backflow mechanism, in frame 1.The filling valve is noncontact
Formula filling valve.The filling valve has the liquid material of temperature requirement when being used for filling.
The filling valve includes the feed pipe for infusion fluid material that the valve seat 2 in frame 1 is connected with valve seat 2
The backflow mechanism 4 that road 3 is connected with valve seat 2.The backflow mechanism 4 include connected with valve seat 2 reflux line 41, located at return duct
The recycle control valve 42 whether flowed into for the liquid material in control valve seat 2 in reflux line 41 on road 41.Obviously, flow back
Control valve 42 is located at outside valve seat 2.Not during filling liquid material, recycle control valve 42 is opened, and reflux line 41 will be remained in valve seat 2
Liquid be back in the recovery point that client specifies.Bottle clip is additionally provided with frame 1, bottle clip is used to clamp filling bottle.Filling bottle position
In the lower section of valve seat 2.
The valve seat 2 includes cavity 5, the up and down valve element 6 in the cavity 5, for driving, the valve element 6 is downward to be transported
Dynamic valve opening driver 7, the seal 8 located at the bottom of valve element 6.Valve opening driver 7 is located at the top of valve element 6, and valve opening drives
The external part of device 7 is inconsistent with the top of valve element 6.The bottom of cavity 5 is extended inwardly to form for the seal cavity 5 of fit seal 8
Extension 9.In the present embodiment, the extension 9 is located at the top of the seal 8.The seal 8 is to be located on the bottom of valve element 6
The sealing ring in portion.
The back-moving spring 10 for being resetted to the valve element 6 depressed is provided between the valve seat 2 and the valve element 6.Reset bullet
The upper end of spring 10 is contradicted on valve element 6, and the lower end of back-moving spring 10 is contradicted on valve seat 2.
Filling valve also includes the flowmeter 11 on feed pipe 3.Set when being reached by the liquid material of flowmeter 11
During fixed amount, valve opening driver 7 resets, and the upward jack-up valve element 6 of back-moving spring 10 makes it reset.
The course of work of lower the present embodiment is illustrated in detail below：
When filling, the liquid material of design temperature is entered in the cavity 5 of valve seat 2 by feed pipe 3, valve opening driver 7
Drive valve element 6 to move downward, make the sealing ring of the bottom of valve element 6 away from the extension 9 of the bottom of cavity 5, enter liquid material and fill
In bottling, when the amount of setting is reached by the liquid material of flowmeter 11, valve opening driver 7 resets, and back-moving spring 10 is upward
Jack-up valve element 6 makes it reset, and cavity 5 is closed.When not filling, recycle control valve 42 is opened, make the liquids remained in cavity 5
Stream enters in reflux line 41, the recovery point that centralized recovery to client is specified.
Above-described embodiment only to illustrate technology design of the present utility model and feature, technique is familiar with its object is to allow
Personage will appreciate that content of the present utility model and implement according to this, protection domain of the present utility model can not be limited with this.
All equivalent change or modifications made according to the utility model Spirit Essence, should all cover protection domain of the present utility model it
It is interior.
