Abstract

The utility model discloses a pneumatic penetration type gate valve which comprises a valve body (2), a valve seat (1), a gate (3), a filler (5) and a filler gland (6), wherein a filler box (4) is arranged between the valve body (2) and the filler gland (6); and the filler (5) is arranged in the filler box (4). The filler box is arranged between the valve body and the filler gland; according to the filler box, the filler mounting height is increased, even if the surface of the gate is scratched in the using process, the filler in the filler box is prevented from being worn, and the phenomenon that the medium liquid is leaked is avoided; and therefore, the service life of the product is greatly improved, the field maintenance rate of the product is reduced, and the safety performance is improved.

Description

Pneumatic penetration gate valve
Technical field
The present invention relates to a kind of valve, specifically relate to a kind of gate valve.
Technical background
At present, pneumatic penetration gate valve uses under some bad working environments (pipeline medium normally contains the paper pulp of iron nail, scum), be prone to flashboard surface abrasion phenomenon, cause filler in this gate valve by the flashboard scratch, so that leak outside at Gland place's generation media fluid, have certain potential safety hazard, and this valve is not long working life yet.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, and provide a kind of its flashboard in use can not may wear to the pneumatic penetration gate valve of filler.
Purpose of the present invention realizes by following technical solution: pneumatic penetration gate valve, comprise valve body, valve seat, flashboard, filler and Gland, and between described valve body and Gland, Stuffing box is housed, described filler is contained in this Stuffing box.
After adopting the present invention, install a Stuffing box additional at valve body and Gland position, the increase of this Stuffing box, improved the setting height(from bottom) of filler, even the scratch phenomenon occurs in flashboard in use its surface, can not may wear to the filler that is contained in Stuffing box the inside yet, the media fluid phenomenon that leaks outside just can not occur yet.Thereby greatly improved the working life of product, reduced the field maintenance factor of product, and improved Safety performance.
Description of drawings
Fig. 1 is the assembly structure schematic diagram of the pneumatic penetration gate valve of the present invention.
Embodiment
With reference to accompanying drawing 1, the pneumatic penetration gate valve of the present invention, comprise valve body 2, valve seat 1, flashboard 3, filler 5 and Gland 6, between described valve body 2 and Gland 6, Stuffing box 4 is housed, described filler 5 is contained in this Stuffing box 4 (and being covered by Gland 6).Wherein, Gland 6 is contained on valve body 2 by the combination of bolt 7, nut 8.Flashboard 3 final controlling element 9 outer with being contained in this gate valve is connected, and by final controlling element, move up and down (open and close that are gate valve) of flashboard controlled.Because the lower end of flashboard generally can not be subject to the wearing and tearing of fed sheet of a media, therefore described Stuffing box 4 is contained in the top of valve body 2, the bottom of valve body does not just need to install Stuffing box, has so saved certain production, installation cost yet.

Claims (2)

1. pneumatic penetration gate valve, comprise valve body (2), valve seat (1), flashboard (3), filler (5) and Gland (6), it is characterized in that: between described valve body (2) and Gland (6), Stuffing box (4) is housed, described filler (5) is contained in this Stuffing box (4).
2. pneumatic penetration gate valve as claimed in claim 1, it is characterized in that: described Stuffing box (4) is contained in the top of valve body (2).
