Abstract
The invention discloses a kind of filling valve, including valve body and the movable piston rod in valved tube body, the mouth of pipe of valve bottom of the pipe is arranged to filling exit, and it is provided with input hole on valve body, the space for connecting the input hole and filling exit is left between the piston rod in valved tube body, piston-rod lower end, which is provided with, can correspond to the plug for blocking filling exit, filling exit inwall is corresponding with the plug lateral wall, plug is provided with the antidrip small opening of negative-pressure vacuum, and the ultravacuum hole connected with the antidrip small opening is provided with piston rod.This filling valve forms pressure using the symmetrical structure of piston rod and filling exit and liquidated, and directly alleviates torrent, allows under filling working condition spilled oil, filling valve are not converted into negative pressure of vacuum and keep not water clock held stationary after closing, and it is wide to be applicable measuring fixed amount scope.
Description
Technical field
The present invention relates to a kind of filling valve.
Background technology
The problem of conventional filling valve often has spilled oil and water clock under filling working condition, particularly buffers vertical
Food-grade operated pneumatic valve, in the measuring fixed amount pouring process of different set, filling unstable, spilled oil and water clock can more can show
Write and cause filling a variety of inconvenience, it is necessary to be improved to filling valve, to solve these industry problems.
The content of the invention
For overcome the deficiencies in the prior art, present invention offer one kind can alleviate torrent and keep filling steady, Er Qieke
Vacuum prevents the filling valve of water clock after closing.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of filling valve, including valve body and the movable piston rod in valved tube body, the pipe of valve bottom of the pipe
Mouth is arranged to filling exit, and input hole is provided with valve body, is left in valved tube body between the piston rod and connects institute
The space of input hole and filling exit is stated, piston-rod lower end, which is provided with, can correspond to the plug for blocking filling exit, filling exit inwall and institute
It is corresponding to state plug lateral wall, plug is provided with the antidrip small opening of negative-pressure vacuum, and is provided with piston rod and the antidrip small opening
The ultravacuum hole of connection.
As the improvement of above-mentioned technical proposal, the plug is connected with piston rod thread, is also threaded with piston rod
The adjustable adjusting nut for abutting plug.
As the further improvement of above-mentioned technical proposal, sealing ring, the sealing are equipped with the lateral wall of the plug
Snare is put in the groove of plug lateral wall and flexibly protrudes from plug outer side surface.
Further, the plug outer side surface is arranged to symmetrical taper in tip edge, and the filling exit inwall is corresponding
Set tapered.
Further, the valve body passes through bolt or screw fit screw by three sections of body assembly and connections, three sections of bodys
It is fastenedly connected.
The beneficial effects of the invention are as follows：This filling valve forms pressure using the symmetrical structure of piston rod and filling exit and liquidated,
Directly alleviate torrent, allow under filling working condition spilled oil, filling valve are not converted into negative pressure of vacuum and kept not held stationary after closing
Water clock, it is wide to be applicable measuring fixed amount scope.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the mounting structure sectional view of closed mode of the present invention；
Fig. 2 is the mounting structure sectional view of opening of the present invention.
Embodiment
Referring to Figures 1 and 2, a kind of filling valve of the invention, including in straight tube-like valve body 1 and movable be arranged on
Piston rod 2 in valve body 1, the mouth of pipe of the lower end of valve body 1 is arranged to filling exit 11, and is provided with valve body 1 defeated
Enter hole 12, the space for connecting the input hole 12 and filling exit 11, piston are left between the piston rod 2 in valve body 1
The lower end of bar 2, which is provided with, can correspond to the plug 21 for blocking filling exit 11, and the inwall of filling exit 11 is corresponding with the lateral wall of plug 21, block up
First 21 top is provided with the antidrip small opening 211 of negative-pressure vacuum, and is provided with what is connected with the antidrip small opening 211 in piston rod 2
Ultravacuum hole.
As the improvement of above-mentioned embodiment, the plug 21 is threadedly coupled with piston rod 2, and screw thread company is gone back on piston rod 2
It is connected to the adjusting nut 22 of adjustable abutting plug 21.
As the further improvement of above-mentioned embodiment, sealing ring 23 is equipped with the lateral wall of the plug 21, it is described
Sealing ring 23 is nested with the groove of the lateral wall of plug 21 and flexibly protrudes from the outer side surface of plug 21.
The outer side surface of plug 21 is arranged to symmetrical taper in tip edge, and the inwall of filling exit 11 is correspondingly arranged
It is tapered, there is cushioning effect flow velocity more stable under pressure.
The valve body 1 is connected by three sections of body assembly and connections, three sections of bodys by bolt or the fastening of screw fit screw
Connect.
It is described above, the simply better embodiment of the present invention, but the present invention is not limited to above-described embodiment, as long as
It reaches the technique effect of the present invention with any same or similar means, should all fall under the scope of the present invention.
