Description
Technical field
This utility model relates to valve technology field, is specifically related to sylphon seal pneumatic filling and dosing valve.
Background technology
Fill and the dosing valve of conventional film chip architecture, piston structure or ball-valve structure are short for service life, and response speed is slow, and volume is bigger than normal, and maintenance cost is high.
Utility model content
The purpose of this utility model is the defect for prior art and deficiency, a kind of simple in construction, sylphon seal pneumatic filling reasonable in design, easy to use and dosing valve are provided, it is compact to design, service life extends, fast response time, maintenance cost is low, and valve pocket dead band is little, can be widely used in the industries such as fill, dosing, gas purging.
In order to solve the problem existing for background technology, the technical solution adopted in the utility model is: it includes valve body, corrugated tube, cylinder, push rod, inlet tube, outlet, cavity, installing hole, valve position feedback device；Described valve inner is provided with a cavity, inlet tube is connected on the left of cavity, below cavity or right side connection outlet pipe, the corrugated tube coincideing with cavity inside it is provided with in cavity, corrugated tube uses PTFE (politef) or PVDF (polyvinylidene fluoride) material, corrugated tube makes cavities seals, corner, four, the top of valve body is respectively equipped with installing hole, cylinder is arranged on the top of valve body, cylinder and valve body are screwed installation, cylinder bottom connects push rod, push rod is connected to the inside of corrugated tube, cylinder sidepiece is provided with a groove, valve position feedback device it is provided with in groove.
Further, described valve body is metal or plastic material valve body.
After using said structure, this utility model has the beneficial effect that it is compact to design, and service life extends, and fast response time, maintenance cost is low, and in valve pocket, dead band is little, can be widely used in the industries such as fill, dosing, gas purging.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Description of reference numerals: valve body 1, corrugated tube 2, cylinder 3, push rod 4, inlet tube 5, outlet 6, cavity 7, installing hole 8, valve position feedback device 9.
Detailed description of the invention
Below in conjunction with the accompanying drawings, this utility model is further described.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with the drawings and the specific embodiments, this utility model is further elaborated.Should be appreciated that detailed description of the invention described herein, only in order to explain this utility model, is not used to limit this utility model.
As it is shown in figure 1, this detailed description of the invention adopts the following technical scheme that it includes valve body 1, corrugated tube 2, cylinder 3, push rod 4, inlet tube 5, outlet 6, cavity 7, installing hole 8, valve position feedback device 9；Described valve body 1 is internal is provided with a cavity 7, inlet tube 5 is connected on the left of cavity 7, below cavity 7 or right side connection outlet pipe 6, the corrugated tube 2 that coincide internal with cavity 7 it is provided with in cavity 7, corrugated tube 2 uses PTFE (politef) or PVDF (polyvinylidene fluoride) material, corrugated tube 2 makes cavity 7 seal, corner, four, the top of valve body 1 is respectively equipped with installing hole 8, cylinder 3 is arranged on the top of valve body 1, cylinder 3 and valve body 1 are screwed installation, connect bottom cylinder 3 and have push rod 4, push rod 4 is connected to the inside of corrugated tube 2, cylinder 3 sidepiece is provided with a groove, valve position feedback device 4 can be installed in groove according to the actual requirements, when cylinder 3 piston movement, can its upper-lower position of perception.
Further, described valve body 1 is metal or plastic material valve body.
When fill or dosing, cylinder 3 promotes push rod 4 to move downward, and promotes corrugated tube 2 down to elapse, seals up the cavity 7 of valve body 1, stops fill or the carrying out of dosing, and valve 1 is closed mode；When cylinder 3 promotes push rod 4 up to move, driving corrugated tube 2 up to move, reopen the cavity 7 of valve body 1, fill or dosing proceed, and valve 1 is opening, and material enters from inlet tube 5, and by outlet 6 out, production is normally carried out.
This detailed description of the invention is compact to design, and service life extends, and fast response time, maintenance cost is low, and valve pocket dead band is little, can be widely used in the industries such as fill, dosing, gas purging.
The above, only in order to the technical solution of the utility model to be described and unrestricted, other amendment or equivalent that the technical solution of the utility model is made by those of ordinary skill in the art, without departing from the spirit and scope of technical solutions of the utility model, all should contain in the middle of right of the present utility model.
