The technological scheme of the utility model is: this band pod apertures high pressure plate valve comprises valve body, valve seat, flashboard and valve rod; Valve rod is connected with flashboard; It is interior and corresponding with the bi-side of flashboard that valve seat is installed in valve body, and valve seat can move along the media flow direction relative to valve body, seals between valve seat and the valve body; Be provided with between valve seat and the valve body and make valve seat rely on the spring of flashboard, valve seat is provided with spoiler.
Described valve seat is provided with and contacted soft seal of flashboard and hard sealing layer, and hard sealing layer is in the outside of soft seal.
Described valve body is equipped with first grease pouring valve outward, and first grease pouring valve is through hole link valve seat on the valve seat and the sealing surface between the flashboard.
" V " type filler is arranged between described valve rod and the valve body; Be provided with spacer ring in the middle of " V " type filler; The outer wall week of spacer ring upwards is provided with circular groove; " V " type filler is compressed by Gland, and valve body is equipped with second grease pouring valve outward, and second grease pouring valve is through the circular groove on the hole link spacer ring on the valve body.
The top of described valve body is equipped with the bleeder valve that communicates with the inner chamber of valve body.
The bottom of described valve body is equipped with the blowdown valve that communicates with the receiving cavity of flashboard.
The utlity model has following beneficial effect: owing to take technique scheme; Push valve seat to flashboard by pressure medium through spoiler, realize sealing, promptly have the DBB function; Each valve seat can both be blocked the pressure from pipeline; Its advantage is that valve still can seal, and has improved the working life of valve if in two valve seats a damage is arranged.Seat design becomes soft, hard double seal, good sealing effect, valve long service life.Simultaneously, the utility model also is equipped with grease pouring valve, bleeder valve and blowdown valve, has the function of low leakage, safety and eliminating dirt.
