Abstract

The invention discloses a reverse pumping type anti-drip filling valve; the filling valve comprises a cylinder arranged in a valve body; a piston rod of the cylinder is fixed by a positioning ring of a valve core; the position of the material outlet of the valve body is provided with at least one layer of wire gauze; the valve core is in the valve body and above the wire gauze; on the positioning ring of the valve core, a sealing ring is arranged between the piston rod of the cylinder and the valve body; the amount of the wire gauze is two layers comprising a first layer wire gauze and a second layer wire gauze; the mesh amount of the first layer wire gauze and/or the second layer wire gauze is 20-30. The filling valve has simple structure, and solves the drip returning problem existing in the low-viscosity or high-viscosity fluid filling process reliably; moreover, the time for pumping the vacuum or blowing the residual materials after the filling is finished is not needed, and therefore the filling efficiency is improved.

Description

Inverse pumping type anti-leakage pouring valve

Technical field

The present invention relates to filling valve, be meant inverse pumping type anti-leakage pouring valve especially.

Background technique

In the filling liquid process, after can finishes, at the discharge port of filling valve " return and drip " (be after can finishes, filling valve discharge port place has 1-2 to drip the phenomenon of material drippage) can appear.

In low viscous filling liquid process, the mode that vacuumizes after adopting can to finish can make " return and drip " problem obtain reasonable solution, but owing to need add vacuum tube at the center of filling valve, make the filling valve complex structure, processing and user cost are all than higher, and it is bigger that control " return drip " effect is influenced by degree of vacuum, if degree of vacuum exists and then controls " return and drip " effect than great fluctuation process and will reduce greatly; In the high viscosity liquid pouring process, the main employing from the filling valve discharge port cut off material, and blow from spool, the mode that the residual material that sticks to the filling valve discharge port is blown off is controlled to return and is dripped, there is complex structure equally in this mode, the difficulty of processing height, processing and user cost are all than problem of higher.

Summary of the invention

In view of this, the invention reside in provides inverse pumping type anti-leakage pouring valve, returns the baroque problem of filling valve of dripping to solve above-mentioned elimination.

For addressing the above problem, the invention provides inverse pumping type anti-leakage pouring valve, comprising:

Be installed in the cylinder in the valve body, the piston rod of cylinder is fixed by the spool positioning ring; The chain link fence of one deck is at least installed at the discharge port place of valve body, described piston rod connect spool in valve body, chain link fence above, described cylinder drives on the described piston rod and draws, and in the time of valve body the material of described chain link fence top is mentioned.

Preferably, on the spool positioning ring, between cylinder piston rod and the valve body seal ring is installed.

Preferably, the quantity of described chain link fence is two-layer, comprises first layer chain link fence, second layer chain link fence.

Preferably, the mesh order number of first layer chain link fence and/or second layer chain link fence is 20-30.

Filling valve of the present invention is simple in structure, and no matter solution reliably is the problem of dripping of returning that exists in low viscosity or the high viscosity liquid pouring process, and vacuumizing or the time of the residual material that blows off after need not can and finishing, and has improved can efficient.

Description of drawings

Schematic representation when Fig. 1 is the inverse pumping type anti-leakage pouring valve bottling condition;

Fig. 2 eliminates the schematic representation that returns when dripping after the inverse pumping type anti-leakage pouring valve can finishes.

Embodiment

For clearly demonstrating the scheme among the present invention, provide preferred embodiment below and be described with reference to the accompanying drawings.

Referring to Fig. 1, filling valve comprises:

Be installed in the cylinder 7 in the valve body 5, the piston rod of cylinder 7 is fixing by spool positioning ring 4; On spool positioning ring 4, between the piston rod of cylinder 7 and the valve body 5 seal ring 6 is installed, two-layer chain link fence is installed at the discharge port place of valve body 5, comprise first layer chain link fence 1, second layer chain link fence 2, the mesh order number of first layer chain link fence 1 and/or second layer chain link fence 2 is 20-30, spool 3 in valve body 5, two-layer chain link fence above.

Inverse pumping type anti-leakage pouring valve mainly adopts the mode that spool 3 is upwards carried throttle down to cut off material, and the benefit of this mode is filling valve spool 3 following materials partly upwards can be taken out, spool 3 actions very fast (can use high-speed cylinder to realize).

The supporting dynamic weighing sensor of this filling valve can be realized the can of weighing automatically, after weighing sensor has detected bottle, send actuating signal and start filling valve, filling valve promptly is in bottling condition shown in Figure 1, and along with the carrying out of pouring process, weighing sensor detects that the can amount reaches the setting requirement in the bottle, promptly control filling valve and stop can this moment, this moment, spool 3 was lifted fast by cylinder 7, and filling valve is closed, and formed as shown in Figure 2 from the discharge port of filling valve to the space 9 of dotted line upwards; Material 8 can not drip in the short time, for the residual material that guarantees various viscosity still can not drip in a long time, also need install the expanded sheet metal that two-layer order number is respectively 20-30 additional at filling valve discharge port place, material can form certain force of strain between the mesh of web plate, can stop following of material.The order number can not be too big or too little, the too little effect that does not then have anti-" return and drip " of order number, and the order number too greatly then can influence filling speed.

Filling valve of the present invention is simple in structure, and no matter solution reliably is " return and the drip " problem that exists in low viscosity or the high viscosity liquid pouring process, and vacuumizing or the time of the residual material that blows off after need not can and finishing, and has improved can efficient.

For the filling valve of being set forth in the embodiment of the invention, within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
