Abstract
The utility model provides a powder body material feeding valve, which comprises a valve body and a valve core assembly, wherein the valve body adopts a cast steel valve body so that the embrittlement crack of the valve body is avoided, the valve core assembly is positioned in a valve cavity of the cast steel valve body and comprises a sealing ring and a valve core, the sealing ring is made of high-wear-resistance rubber materials and is internally embedded in the valve body, in addition, the edge of the sealing ring is outwards projected, a hinging support seat is arranged on the valve core, and the valve core can be tightly pressed onto the projected sealing ring at one side. The powder body material feeding valve has the advantages that the contact is tight, the service life of the valve body can be greatly prolonged, and meanwhile, the operation is more reliable, convenient and fast.
Description
Technical field
The utility model relates to the conveying valve field, is specially a kind of employing cast steel valve body, and the preferable powder inlet valve of sealing property.
Background technology
The powder inlet valve is opened and is cut off adaptable across the pipeline of industry granular materials such as building materials, electric power, chemical industry, metallurgy; The mode that industrial and mining enterprises adopt malleation to blow powder through regular meeting realizes the conveying of bulk powder, and adopts the powder inlet valve to control start and stop and operational throughput that powder is carried.
With regard to prior art, some later-model bulk powder feedways are through the pressure volume pot that powder is housed is pressurizeed, and the mode of inhaling powder with pressure release realizes the powder transmission.Such feedway has higher air-tightness requirement to the pressure volume pot pressurization therebetween to powder charging valve.Therefore and general powder charging valve does not have the air-tightness requirement, and perhaps air-tightness own is less demanding, a kind of later-model powder inlet valve spool need be provided, with the requirement to spool of the valve body that adapts to powder inlet valve in the correlation technique.
The utility model content
The technical matters that the utility model solved is to provide a kind of powder inlet valve, to solve the shortcoming in the above-mentioned background technology.
The technical matters that the utility model solved adopts following technical scheme to realize:
The powder inlet valve comprises valve body and core assembly, wherein; Valve body adopts the cast steel valve body and function having avoided valve body embrittlement, and core assembly is arranged in the valve pocket of cast steel valve body, comprises seal ring and spool; Said seal ring is processed for the high wear-resistant rubber material, is embedded on the valve body, and the edge evagination; Said spool is for being provided with a hinged-support, makes the spool can be in a side compression on the seal ring of protrusion.
In the utility model, said spool face is a smooth ceramic wearing coat.
In the utility model, the sealed sides of said spool can also can be arc for trapezoidal.
Beneficial effect: the utility model adopts the cast steel valve body to avoid valve body embrittlement; Simultaneously, spool has well, contacts closely with seal ring, and increase service life greatly; Cleverly structure design in conveying sudden power, can not open when dying yet, make mass transport more safe and reliable.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the utility model valve circle position details figure.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Relevant scheme drawing referring to the preferred embodiment of the powder inlet valve of Fig. 1, Fig. 2; In the present embodiment, comprise inlet point 5 and discharging opening 1 on the valve body 6, valve body 6 adopts the cast steel valve body; One powder guide cavity 2 is arranged in it; Seal ring 3 is embedded on the powder guide cavity 2, and spool 4 can fit tightly with seal ring 3, and through hinged-support 7 its foldings of control.
More than show and described the advantage of groundwork, principal character and the utility model of the utility model.The technical personnel of the industry should be understood; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification sheets that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
