End connect leader, handle be equipped with a positioning rod.
As the utility model preferred embodiment, the elastomeric pad is stainless steel substrates.
As the utility model preferred embodiment, the valve seat and elastic bottom plate are integrally formed.
The positive pressure dense phase pneumatic conveying system inlet valve of the utility model be provided on valve seat elastic bottom plate and
One elastic top plate, is provided with multiple elastomeric pads between the two elastic plate bodies, and elastomeric pad is located at around valve rod, this
Sample these elastomers when valve body is by frequent vibration can absorb more vibration, and pine is not easy between valve rod and valve body
It is dynamic, the better tightness of valve body.
Description of the drawings
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, other drawings may also be obtained based on these drawings.
Fig. 1 is the dimensional structure diagram of the positive pressure dense phase pneumatic conveying system inlet valve of the utility model.
Specific implementation mode
The preferred embodiment of the utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear to be made to the scope of protection of the utility model
Define.
As shown in Figure 1, a kind of positive pressure dense phase pneumatic conveying system inlet valve 1, including a valve body 10, valve body 10 are equipped with
