Description
Technical field
The utility model belongs to control valve technical field, is specifically related to a kind of elastic packing type gate valve.
Background technique
The gate valve of prior art is mainly made up of valve body, flashboard and operating stem, in valve body, be provided with runner, the two ends of runner are respectively influent stream mouth and go out head piece, surface at flashboard is provided with seal ring, in the time closing a floodgate, seal ring is connected on valve body and realizes and seal combined floodgate, although it can realize sealing combined floodgate performance to a certain extent, but in actual use, because flashboard can regular action, so make the wearing and tearing of seal ring comparatively serious, affect to a certain extent stability in use and the working life of flashboard, be difficult to meet the demand in market.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, the elastic packing type gate valve of good seal performance and long service life.
The technological scheme that realizes the utility model object is a kind of elastic packing type gate valve, comprise valve body, flashboard and operating stem, in described valve body, be provided with inlet passage and outlet passage, the setting that is in line of described inlet passage and outlet passage, described operating stem is connected with the top of described flashboard, in described valve body, be provided with vertical lock groove, described flashboard is movably arranged in described vertical lock groove, joint at described inlet passage and described vertical lock groove is provided with cross groove, in described cross groove, be provided with spring and live metal flashboard, one side of described flashboard is small top and big bottom being obliquely installed, another side is vertically to arrange, described live metal flashboard is big top and small bottom being obliquely installed, the plane of inclination of described flashboard contacts with described live metal flashboard, be provided with caulking gum layer on the surface of described live metal flashboard.
Between described live metal flashboard and described cross groove, be provided with rubber seal bed course.
Between described operating stem and described valve body, be provided with packing cavity and gland, described gland is bolted on valve body and the top of described packing cavity is connected on the lower end surface of gland.
On the plane of inclination of described flashboard, be provided with protection enamel layer.
The utlity model has positive effect: of the present utility model simple in structure, be provided with cross groove, in cross groove, be provided with the live metal flashboard of spring, and a side of flashboard is arranged on to plane of inclination, live metal flashboard is also for plane of inclination arranges simultaneously, in use, flashboard moves down, plane of inclination Compressive activities metal flashboard gradually simultaneously, make live metal flashboard extrusion spring Compress Spring, flashboard completes while damming completely, live metal flashboard is closely connected on the plane of inclination of flashboard and completes sealing function under the self-healing action of spring, on live metal plate, be provided with caulking gum layer simultaneously, because it can also move by Compress Spring in the time that flashboard closes a floodgate together with live metal flashboard, so can effectively reduce wear, extend its working life, good seal performance and long service life on the whole, applicability is good, practical.
Brief description of the drawings
For content of the present utility model is more likely to be clearly understood, according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail below, wherein:
Fig. 1 is structural representation of the present utility model.
Embodiment
(embodiment 1)
