Description
Technical Field
The utility model relates to a RTO is with blowing from pneumatic diverter valve of gas.
Background
In the use process of RTO, the hard ceramic heat storage material slag is easy to drop on the sealing structure of the switching valve, and the valve cannot be completely closed due to the loose fit of the valve plate and the valve seat of the valve. On one hand, the gas leakage causes the reduction of the purification efficiency of the equipment; on the other hand, the valve plate is deformed to cause the complete failure of the valve due to the long-time abrasion and extrusion of the slag, so that the normal operation of the whole RTO equipment is influenced and even the shutdown is caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming prior art not enough and provide a RTO is with from blowing pneumatic switch valve.
In order to achieve the above purpose, the utility model adopts the technical scheme that: a self-purging pneumatic switching valve for RTO comprises a valve body, a valve plate, a valve rod and a control device; the valve body is internally provided with a valve seat, the valve plate is arranged in the valve body and matched with the valve seat, the valve rod penetrates through the valve body, the control device controls the valve rod to rotate, and the valve rod drives the valve plate to open and close; the outer wall of the valve body is provided with an annular air passage, the inner wall of the valve body is provided with a plurality of purging small holes, the annular air passage is communicated with the purging small holes, and the annular air passage is externally connected with compressed air.
Preferably, the annular air passage is wound around the outer wall of the valve body for a whole circle, an air inlet connecting part is arranged on the annular air passage, and a compressed air joint is arranged on the air inlet connecting part.
Preferably, the plurality of blowing small holes are uniformly distributed around the inner wall of the valve body, and the plurality of blowing small holes face to the matching part of the valve plate and the valve seat.
Preferably, the plurality of purging small holes are flat structures.
Preferably, bearing supports matched with the valve rod are arranged on two sides of the valve body.
Because of above-mentioned technical scheme's application, compared with the prior art, the utility model have the following advantage:
the utility model discloses RTO of scheme is with automatic purge pneumatic switch valve, has designed the function that the gas circuit sweeps on the basis of original valve structure, utilizes compressed air source to sweep the valve seat seal structure, simple structure, the operation is reliable; and can effectively sweep debris on the valve seat seal structure, protect seal structure, improve the valve life-span.
Drawings

FIG. 1 is the utility model discloses a RTO is with structure schematic diagram of self-purging pneumatic switching valve.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in the attached drawing 1, the self-purging pneumatic switching valve for RTO of the present invention comprises a valve body 1, a valve plate 2, a valve rod 3 and a control device 4; be provided with disk seat 5 in the valve body 1, valve plate 2 sets up in valve body 1, and valve plate 2 and disk seat 5 cooperation, valve rod 3 pass valve body 1, are provided with on the both sides of valve body 1 with valve rod 3 complex bearing retainer 9, support valve rod 3, and controlling means 4 is used for controlling valve rod 3 to rotate, makes valve rod 3 can drive valve plate 2 and opens and shuts.
Be provided with on the outer wall of valve body 1 around the annular air flue 6 of valve body 1 a week, be provided with air inlet connection portion 8 on the annular air flue 6, installation compressed air connects on the air inlet connection portion 8, can external compressed air source.
The inner wall of the valve body 1 is provided with a plurality of blowing small holes 7, the blowing small holes 7 are uniformly distributed around the inner wall of the valve body 1, and the annular air passage 6 is communicated with the blowing small holes 7, so that compressed air of the annular air passage 6 can be blown out of the blowing small holes 7.
The plurality of blowing small holes 7 face to the matching part of the valve plate 2 and the valve seat 5, namely the sealing part of the valve seat 5, so that compressed air can effectively blow sundry slag on the sealing structure of the valve seat and protect the sealing structure; the air outlet part of the blowing small hole 7 can adopt a flat structure so as to improve the blowing effect.
The above is only a specific application example of the present invention, and does not set any limit to the protection scope of the present invention; all the technical solutions formed by equivalent transformation or equivalent replacement fall within the protection scope of the present invention.
