Abstract
The utility model discloses a hard sealing gate valve valve clack structure of stainless steel rising stem (RS. ), including the outer lane of valve clack, be equipped with the circular shape valve plate on the inner wall of outer lane, the valve plate cross -section is whole to be the wave, and sealed fixed connection between valve plate and the outer lane inner wall is equipped with the round sealing washer, both sides are connected with articulated regulating spindle on the outer wall of outer lane, and the valve plate is upper and lower, bilateral symmetry structure in the outer lane. The utility model discloses structural design is simple and ingenious, adopts curved surface type valve clack structure, and stable in structure is shock -resistant, very big reinforcing the life of valve clack.
Description
Technical field:
This utility model relates to Outside screw stem rising through handwheel type gate valve field, particularly a kind of rustless steel rising stem (RS.) hard seal gate valve valve flap structure.
Background technology:
The opening and closing element of Outside screw stem rising through handwheel type gate valve is flashboard, and the direction of motion of flashboard is perpendicular with flow direction, and gate valve can only make standard-sized sheet and fully closed, it is impossible to makes adjustments and throttles.
The shortcoming of Outside screw stem rising through handwheel type gate valve is as follows:
Easily cause erosion and scratch between sealing surface, keep in repair relatively difficult；Overall dimensions is relatively big, opens and needs certain space, and opening/closing time is long；Structure is more complicated.
Utility model content:
The purpose of this utility model is to solve the deficiencies in the prior art, and a kind of rustless steel rising stem (RS.) hard seal gate valve valve flap structure provided.
The technical solution adopted in the utility model is:
Rustless steel rising stem (RS.) hard seal gate valve valve flap structure, outer ring including flap, it is characterized in that: described outer ring inwall is provided with the valve plate of circle, valve plate cross section entirety undulate, being sealedly and fixedly connected between valve plate and outer ring inwall, outer ring outer wall is provided with a circle sealing ring, both sides connection has hinged regulation axle.
Described rustless steel rising stem (RS.) hard seal gate valve valve flap structure, it is characterised in that: described valve plate is upper and lower, bilateral symmetry in outer ring.
Compared with prior art, the beneficial effects of the utility model are:
The design of this utility model structure is simple and ingenious, uses curved face type valve flap structure, Stability Analysis of Structures impact resistance, enhances the service life of flap greatly.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the cross section view in this utility model Fig. 1 at A-A.
Detailed description of the invention:
Below in conjunction with the accompanying drawings, by embodiment, this utility model is described in further detail:
Rustless steel rising stem (RS.) hard seal gate valve valve flap structure, outer ring 1 including flap, outer ring 1 inwall is provided with the valve plate 2 of circle, valve plate 2 cross section entirety undulate, it is sealedly and fixedly connected between valve plate 2 and outer ring 1 inwall, outer ring 1 outer wall is provided with a circle sealing ring, both sides connection has hinged regulation axle 3, and valve plate 2 is upper and lower, bilateral symmetry in outer ring 1.
Above-described embodiment is only preferably embodiment of the present utility model, and in addition, this utility model can also have other implementations.It should be noted that on the premise of conceiving without departing from this utility model, within any conspicuously improved and modification all should fall into protection domain of the present utility model.
