The utility model is provided with a contour cover between valve body and cylinder, by coated for the piston rod joint of the push rod of valve and cylinder, can prevent dust to be entered cylinder interior by the piston rod of cylinder, extend cylinder working life, the setting of double valve plates simultaneously, improve the sealability of valve, improve the using effect of valve.
Preferably, described valve body and contour cover joining place are provided with the first closed loop seal ring, stuffing box gland, the second closed loop seal ring, opening seal ring successively, and described first closed loop seal ring, stuffing box gland, the second closed loop seal ring, opening seal ring are all set on push rod fastening by an octagon nut.
This kind of structure can improve the sealability between valve body and the push rod of valve greatly, and the especially setting of opening seal ring, makes the laminating of each seal ring and stuffing box gland and push rod and valve body tightr.
Preferably, described push rod end is provided with coupling sleeve, and described Compress Spring is arranged in coupling sleeve and two ends and is exposed to that coupling sleeve is outer to be pressed on valve plate by bulb top, and described coupling sleeve side is connected with push rod end with a connecting stud by a connecting head.
This kind of structure makes the connection of push rod and Compress Spring more solid and reliable, is convenient to Compress Spring simultaneously and presses the top of valve plate, improves the sealability of valve.
Preferably, be provided with groove inside described valve plate, described coupling sleeve two ends are stretched in the groove of two valve plates respectively.
When this kind of structure can prevent Compress Spring top pressure valve plate, the displacement of valve plate, makes its sealing effect better.
Preferably, on described valve gap, medium manhole appendix outer ring is provided with seal ring, and diameter and the valve plate outer side surface diameter of described seal ring match.
This kind of structure makes the sealing effect at valve plate and valve gap place better.
Preferably, two valve gaps of valve body both sides are tightened together by some socket head screws.
This kind of structure makes its overall structure compacter, and fastness is higher.
The utility model is provided with a contour cover between valve body and cylinder, by coated for the piston rod joint of the push rod of valve and cylinder, can prevent dust to be entered cylinder interior by the piston rod of cylinder, extend cylinder working life, the setting of double valve plates simultaneously, improve the sealability of valve, improve the using effect of valve.
