The technical solution of the utility model is: a kind of Novel regulating valve door, comprise valve body, valve gap and valve rod, the intracavity inter-connection of described body cavity and valve gap, described valve body upper end is connected with valve gap, the upper end of valve gap is connected with pressing plate, in described body cavity, be provided with valve rod, valve rod enters into body cavity through the through hole on pressing plate, described valve body, on the inwall of valve gap and valve rod, be all equipped with the lined with fluoroplastic bed of material, described pressing plate is convex shape, and protruding end is embedded in the first groove of valve gap upper end, between protruding end and the first groove, be provided with the first retainer ring, between the tongue of described valve gap lower end and the second groove of valve body upper end, be provided with the second retainer ring, valve rod is successively through the first retainer ring, the second retainer ring, and and between retainer ring, be provided with gap, on valve rod outer wall, offer vertically two symmetrical liquid outlet grooves, valve rod lower end is provided with the spool being connected as a single entity, between the valve rod of the second retainer ring below and spool, be provided with corrugated tube, in described spool, be fixedly installed metalwork, spool is connected with threaded stem by metalwork, the lower end of described spool is tapered slope, valve interior wall is provided with the valve body inclined-plane matching with tapered slope.
Further, described valve body and valve gap, valve gap and pressing plate are by together with being fixed of screw rod and nut.
Further, the through hole contacting point of described valve rod and pressing plate is provided with O type circle.
Further, the material of described first and second retainer ring is rigid material.
Further, the contacting point of described valve rod and first and second retainer ring is provided with rubber seal.
Further, the cone angle of described tapered slope is 30 °～60 °.
Further, the cone angle of described tapered slope is 45 °.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, spool and metalwork are made as one, and liquid cannot be eroded on valve rod; Between the lower end of spool and valve body, be that the conical surface contacts, granular like this impurity can not rest on sealing surface, has effectively protected sealing surface; Between pressing plate and valve gap upper end, valve gap lower end and valve body, be provided with retainer ring, and be provided with liquid outlet groove on valve rod, greatly improved the vibration of spool, resisted the intensity of fluid impact, improved the life-span of valve.

Embodiment
As Figure 1-3,
The technical solution of the utility model is: a kind of Novel regulating valve door, comprise valve body 1, valve gap 2 and valve rod 3, the intracavity inter-connection of described valve body 1 inner chamber and valve gap 2, described valve body 1 upper end is connected with valve gap 2, the upper end of valve gap 2 is connected with pressing plate 4, in described valve body 1 inner chamber, be provided with valve rod 3, valve rod 3 enters into valve body 1 inner chamber through the through hole on pressing plate 4, described valve rod 3 is provided with O type circle with the through hole contacting point of pressing plate 4, described valve body 1 and valve gap 2, valve gap 2 and pressing plate 4 are by together with being fixed of screw rod and nut, described valve body 1, on the inwall of valve gap 2 and valve rod 4, be all equipped with the lined with fluoroplastic bed of material, described pressing plate 4 is convex shape, and protruding end 5 is embedded in the first groove of valve gap 2 upper ends, between protruding end 5 and the first groove, be provided with the first retainer ring 6, between the tongue 7 of described valve gap 2 lower ends and the second groove of valve body 1 upper end, be provided with the second retainer ring 8, valve rod 3 is successively through the first retainer ring 6, the second retainer ring 8, and and between retainer ring, be provided with gap, described valve rod 3 and first, the contacting point of two retainer rings is provided with rubber seal, described first, the material of two retainer rings is rigid material, on valve rod 3 outer walls, offer vertically two symmetrical liquid outlet grooves 9, ensure that cavity cavity pressure and valve body cavity pressure that valve rod 3 forms at retainer ring reach balance, valve rod 3 lower ends are provided with the spool 10 being connected as a single entity, between the valve rod 3 of the second retainer ring 8 belows and spool 10, be provided with corrugated tube 11, alleviate vibration when valve rod 3 is worked, improve the working stability of valve, in described spool 10, be fixedly installed metalwork 12, spool 10 is threaded with valve rod 3 by metalwork 12, effectively ensure the impact resistance of spool 10, the lower end of described spool 10 is tapered slope 13, the cone angle of described tapered slope 13 is 45 °, valve body 1 inwall is provided with the valve body inclined-plane 14 matching with tapered slope.
