Description
Technical field
The utility model relates to suck back valve apparatus field, in particular to a kind of biliquid suck back valves.
Background technique
Suck back valve is also known as resorption type glue dispensing valve, is the important component of dispenser, is specially to control liquid, and incite somebody to action
Pouring liquid, smearing, encapsulating are in the equipment of product surface or interiors of products, and dispenser is due to generally using air pump to provide pressure
Dispensing is carried out, then it when air pump works repeatedly, since the indoor pressure of glue changes repeatedly, is easy in dispensing valve outlet
Leak adhesive causes water clock, wire drawing, in turn results in the waste of glue, and in addition most glue dispensing valves can only all provide a kind of output of glue,
It also needs to be additionally provided other glue dispensing valve when being used cooperatively sometimes for biliquid to need dispenser higher to be used cooperatively
It is required that and needing to occupy more spaces.
Utility model content
The technical problems to be solved in the utility model is to overcome the above technological deficiency, provides a kind of stopping dispensing timely resorption
Glue, can be with biliquid while a kind of biliquid suck back valve for dispensing glue.
In order to solve the above technical problems, technical solution provided by the utility model are as follows: a kind of biliquid suck back valve, including valve
Body, the valve body include the cylinder set gradually from bottom to top, connection valve, are located in same level into glue valve and two and put down
The plastic emitting valve of row setting, the cylinder is interior to be equipped with piston and spring, and the top that piston is located on the cylinder sidewall is equipped with
Air inlet, the piston can slide up and down in cylinder, and the spring one end connects piston, and the other end connects cylinder bottom
Portion, the spring inner sleeve are taken over a job stopper rod, and the piston rod upper end connects piston, and the piston-rod lower end is set to connection valve
Interior, the piston-rod lower end portion is connected with connecting rod, and the connecting rod two end is separately connected the valve rod being equipped with straight down, institute
The valve rod lower end stated passes through and is respectively arranged in plastic emitting valve into glue valve, and the valve rod is slidably matched with into glue valve, the valve
Bar lower end is equipped with sealing-plug, and sealing-plug is closely connect with into glue valve bottom end under natural conditions, described into right on glue valve side wall
Title is set there are two glue-feeder, described to be respectively equipped with annular channel into connection glue-feeder inside glue valve, under the annular channel
End connection plastic emitting valve, the plastic emitting valve bottom is equipped with gum outlet.
The utility model compared with prior art the advantages of be: by air inlet to cylinder intake, piston is made to move down pressure
Contracting spring, while piston rod is driven, piston-rod lower end is moved under the promotion of piston rod by two valve rods that connecting rod connects, from
And make to be detached from into glue valve bottom end and sealing-plug, glue is introduced into from glue-feeder flows through annular channel and enter in plastic emitting valve, from plastic emitting valve
The discharge of bottom gum outlet, when cylinder interior gas is discharged, spring force drives piston rod to move up, and linkage effect is lower so that sealing-plug
It is closely connect with into glue valve bottom end again, because moving up for sealing-plug makes the negative pressure generated in plastic emitting valve while stopping into glue
Obtain plastic emitting chewing-gum liquid resorption, it is therefore prevented that the situations such as water clock, two plastic emitting valves are independent of each other during for dispensing glue, can lead to simultaneously
It crosses two glue-feeders and inputs different glues, only can also input glue to a glue-feeder, so that a suck back valve has two
A independent dumping mouth, it is easy to operate, reduce space hold.
As an improvement, described be tightly connected into glue valve and plastic emitting valve, prevent glue from leaking.
As an improvement, to be that upper end is small, lower end is big round table-like for the sealing-plug, facilitate glue close along first when into glue
The circumferential surface of blocking falls, and not will cause accumulation of the glue on the first sealing-plug.
As an improvement, the plastic emitting valve bottom is the arc of evagination, glue is avoided to spread in plastic emitting valve, it is convenient from out
Glue is discharged in Jiao Kou.

Specific embodiment
The following describes the utility model in further detail with reference to the accompanying drawings.
In conjunction with Fig. 1, a kind of biliquid suck back valve, including valve body 1, the valve body 1 include the gas set gradually from bottom to top
Cylinder 2, connection valve 3 are located at plastic emitting valve 5 disposed in parallel in same level into glue valve 4 and two, are equipped in the cylinder 2
Piston 2.1 and spring 2.2, the top that piston 2.1 is located on 2 side wall of cylinder are equipped with air inlet 2.3, the piston
2.1 can slide up and down in cylinder 2, and described 2.2 one end of spring connects piston 2.1, and the other end connects 2 bottom of cylinder, institute
2.2 inner sleeve of spring stated is taken over a job stopper rod 2.4, and 2.4 upper end of piston rod connects piston 2.1,2.4 lower end of piston rod
In connection valve 3,2.4 lower end of piston rod is connected with connecting rod 6, and 6 both ends of connecting rod, which are separately connected, to be equipped with
Valve rod 7 straight down, 7 lower end of valve rod pass through and are respectively arranged in plastic emitting valve 5 into glue valve 4, the valve rod 7 with into glue
Valve 4 is slidably matched, and 7 lower end of valve rod is equipped with sealing-plug 7.1, under natural conditions sealing-plug 7.1 with into 4 bottom end of glue valve
Close connection, it is described into being symmetrically arranged with two glue-feeders 4.1 on 4 side wall of glue valve, it is described into being connected to glue-feeder inside glue valve 4
4.1 are respectively equipped with annular channel 4.2, and 4.2 lower end of annular channel is connected to plastic emitting valve 5, and 5 bottom of plastic emitting valve is all provided with
There is gum outlet 5.1.
Described is tightly connected into glue valve 4 and plastic emitting valve 5, and the sealing-plug 7.1 is the rotary table that upper end is small, lower end is big
Shape, 5 bottom of plastic emitting valve are the arc of evagination.
The utility model in the specific implementation, by air inlet 2.3 to 2 air inlet of cylinder, makes piston 2.1 move down compressed spring
2.2, while the piston rod 2.4 connecting with piston 2.1 is driven, 2.4 lower end of piston rod is existed by two valve rods 7 that connecting rod 6 connects
It is moved under the promotion of piston rod 2.4, to make to be detached from into 4 bottom end of glue valve and sealing-plug 7.1, introduces glue stream from glue-feeder 4.1
