Description
Technical field
This utility model relates to a kind of valve, specifically refers to a kind of top dome type shunt valve.
Background technology
Hanging down in pendant induction system at medicine intermediate and fine chemistry industry production field, conveying is dried or partial desiccation powder material, needs
Shunt valve to be installed carries out the shunting of material or confluxes.Powder granule due to its solid characteristic than for gas or liquid more
There is abrasiveness mobility simultaneously the poorest.Traditional valve designs the earliest due to it and is used to locate process gases and liquid, used
Softer, elastic sealing ring is the most easily to be scratched and make valve not reach needs of expected design at conveying powder granule.Make now
Shunt valve generally use flashboard type structure, powder granule material are retained by flashboard at valve closing and produce at sealing
Pile up, thus hinder the of completely closed of valve；It is exposed to the soft seal circle powder granule to be stood that material flows through on direction
Constantly impact is worn and torn greatly, causes valve to work.Seal replacing to need to pull down whole valve, maintenance maintenance
Trouble, has a strong impact on production.
Utility model content
The weak point existed for above-mentioned prior art, this utility model is to provide a kind of top dome type shunt valve, it is possible to have
Effect solves the problem that above-mentioned prior art exists.
The technical solution of the utility model is as follows:
A kind of top dome type shunt valve, including shunt valve valve body, it is corresponding that the lower section of described shunt valve valve body is symmetrically arranged on two with twice
Discharging opening, described discharging opening device respectively has corresponding tapping channel, and the inside of described shunt valve valve body is sphere, described
Being provided with two spools matched with described twice discharging opening respectively in shunt valve valve body, described spool is segment；Described two
One end of individual spool by driving stem shaft to be connected to be installed on the drive shaft of the pneumatic actuator of shunt valve valve body side, two
The other end of individual spool is connected to be installed on the driven stem shaft of shunt valve valve body opposite side；The discharging opening of described shunt valve valve body
Device equal with the junction of tapping channel has the sealing ring coordinated with spool.
The one end of the discharging opening that described tapping channel is connected to described shunt valve valve body is provided with corresponding locating flange, described discharging
Passage passes through its locating flange being provided with and the corresponding bolt adapting device discharge outlet to described shunt valve valve body.
The material of described sealing ring is the one in modified ptfe or PEEK.
Implement the technical solution of the utility model, have the advantages that
The inside of shunt valve valve body of the present utility model is sphere, is provided with and matches with twice discharging opening respectively in shunt valve valve body
Two spools closed, one end of two spools is connected to be installed on the pneumatic execution of shunt valve valve body side by driving stem shaft
The drive shaft of mechanism, the other end of two spools is connected to be installed on the driven stem shaft of shunt valve valve body opposite side, and spool can
With under the drive of pneumatic actuator, in shunt valve valve body, do swing operating, both played sealing function, and played again remnants
The propelling movement effect of material, thus solve material and retain and at sealing, produce the problem piled up；
The one end of the discharging opening that tapping channel of the present utility model is connected to shunt valve valve body is provided with corresponding locating flange, discharging
Passage passes through its locating flange being provided with and the corresponding bolt adapting device discharge outlet to shunt valve valve body, long at sealing ring
The when that time operating being lost efficacy, can manage from conveying without by overall for valve easily at seat in the plane dismounting and change sealing ring
Line is pulled down, and shortens the maintenance maintenance time；
The material of sealing ring of the present utility model is the one in modified ptfe or PEEK, have resistance to creep, wear-resistant, from
Greasy property, thus ensure ring wear resistant, scratch resistance, durable in use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A sectional view in Fig. 1.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, to this practicality
Novel it is described in further detail.
With reference to Fig. 1, Fig. 2, a kind of top dome type shunt valve, including shunt valve valve body 1, the lower section two of described shunt valve valve body 1
Side is arranged with the corresponding discharging opening of twice, and described discharging opening device respectively has corresponding tapping channel 2, described shunt valve valve
The inside of body 1 is sphere, is provided with two spools matched with described twice discharging opening respectively in described shunt valve valve body 1
3, described spool 3 is segment；One end of said two spool 3 is connected to be installed on shunt valve valve by driving stem shaft 4
The drive shaft of the pneumatic actuator 5 of body 1 side, it is another that the other end of two spools 3 is connected to be installed on shunt valve valve body 1
The driven stem shaft 6 of side；The discharging opening of described shunt valve valve body 1 has and spool with the equal device in junction of tapping channel 2
3 sealing rings 7 coordinated.
The one end of the discharging opening that described tapping channel 2 is connected to described shunt valve valve body 1 is provided with corresponding locating flange 21, institute
State tapping channel 2 and pass through its locating flange 21 being provided with and corresponding bolt 8 adapting device to described shunt valve valve body 1
Discharge outlet.The material of described sealing ring 7 is modified ptfe.
Spool 3 of the present utility model can do swing operating under the drive of pneumatic actuator 5 in shunt valve valve body 1,
Both played sealing function, and played again the propelling movement effect of salvage stores, thus solve material and retain and at sealing, produce accumulation
Problem.
The above is only preferred implementation of the present utility model, it is noted that for the ordinary skill people of the art
For Yuan, on the premise of without departing from this utility model principle, it is also possible to make some improvements and modifications, these improve and profit
Decorations also should be regarded as protection domain of the present utility model.
