Description
Technical field
The utility model relates to lithium battery industries, produce star-like baiting valve more particularly, to a kind of lithium battery.
Background technique
Star-like baiting valve, also known as star-shaped discharge valve, star-like baiting valve is as a kind of simple and efficient conveying equipment, extensively
It is also one of indispensable tool in lithium electricity industry applied to powder body material industry.
Currently, most star-like baiting valves only with single layer due to sealing, sealing effect is bad, does not reach requirement, no
The delivery requirements of lithium battery material are able to satisfy, a kind of sludge star-shaped discharge valve, star-like blade as disclosed in CN207275772U
Side and cabinet between there are gap, the strip gab parallel with axis is set on cabinet, and opening setting is upper and lower staggered soft
Property sealing blend stop, this sludge star-shaped discharge valve sealing effect is bad, often occur star-like baiting valve to seize up even stop
The phenomenon that operating.
In addition, production lithium battery material needs to be conveyed by star-like baiting valve in lithium electricity industry, work as positive electrode
In there are when metal impurities, will cause self-discharge of battery, and self discharge will cause fatal influence to lithium ion battery, and current
The star-like baiting valve overwhelming majority on the market uses cast iron quality, and metallic foreign body is mixed into lithium battery processing materials in order to prevent,
The lithium electricity industry star-like baiting valve for mainly using surface sprayed wc, but the service life of tungsten carbide coating is short, works as coating
When falling off because of abrasion, lithium battery processing will be contacted with material with the metallics of star-like baiting valve, to influence to produce
Product quality, and such case is unable to monitor at all, is replaced in time, and unstable product quality is caused.
Utility model content
Technical problem to be solved by the utility model is: overcome the deficiencies of the prior art and provide a kind of sealing effect it is good, can
The lithium battery of the phenomenon that effectivelying prevent lithium battery self discharge, energy real-time monitoring valve body and spool abrasion condition produces star-like blanking
Valve.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of lithium battery produces star-like blanking
Valve, including valve body, valve body is interior to be equipped with shaft, spool, inlet port and outlet port, and the valve body is externally provided with bearing block, the shaft
It is connect with spool by spline across bearing block, the shaft and motor axis connection；It is equipped between the spool and bearing block close
Seal link stopper；Sealing link stopper is boss ladder labyrinth seal structure, and Simmer ring is equipped between bearing block and shaft.
Further, the valve body and spool are made of nonmetallic materials, it is preferable that valve body and spool use nylon monomer-cast nylon material
Material is made.
Further, the position that the bearing block is connect with Simmer ring is equipped with compacting ring, position of the compacting ring to Simmer ring
It sets and is defined, be fitted in Simmer ring preferably on shaft side wall, realize good sealing, and then improve star-like baiting valve
Sealing performance；Meanwhile Simmer ring sideslip is prevented, after sealing ring part wears, moreover it is possible to be carried out by bolt to compacting ring
It compresses, can continue to realize more preferable sealing effect.
Further, the discharge port is inverted U-shaped opening.
The utility model has the beneficial effects that
1. due to the star-like baiting valve of conventionally employed single layer sealing, poor sealing, the material in star-like baiting valve is easy
Penetrate into shaft, spool, between bearing block, the place for causing them to contact with each other frictional force due to feed blocking increases, and makes star
There is the phenomenon that even shutting down to seize up in type baiting valve, relative to single layer sealing structure, the star-like baiting valve of the application,
Dual-seal is carried out using sealing link stopper and Simmer ring, sealing effect is good, the phenomenon that lithium battery material leaks is effectively prevented,
Extend the service life of equipment.
2. valve body and spool are nylon monomer-cast nylon material, efficiently solving lithium battery anode and containing metal material leads to self discharge
The problem of.
3. discharge port is inverted U opening, increase openings of sizes, effectively prevent putty, and it is real-time to be open by inverted U
Monitor spool and valve body wear situation.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1-is the utility model structure diagram.
Above-mentioned appended drawing reference: 1- valve body, 2- shaft, 3- spool, 4- feed inlet, 5- discharge port, 6- bearing block, 7- seal shelves
Block, 8- Simmer ring.
Specific embodiment
The following is a further explanation of the present invention with reference to the accompanying drawings and embodiments.
Referring to Fig.1, a kind of lithium battery produces star-like baiting valve, including valve body 1, in valve body 1 equipped with shaft 2, spool 3,
