Abstract

In a kind of high pressure of the utility model, cleaning type gate valve relates to gate valve technical field, solve that the sealing surface of gate valve of the prior art is secondary easily produces the technical problem of leakage due to greasy dirt, comprise valve body, be installed on the valve gap of valve body upper shed, it is characterized in that: also comprise the small ball be arranged on valve gap and the sewage draining exit blocked with blowdown plug being arranged at valve body lower portion; Also comprise and be arranged at spirotallic gasket between valve body and valve gap, and be connected with fastening nuts by stud bolt; The utility model product is when the attachment of sealing surface generation greasy dirt, when flashboard produces other dirts, the valve gap of its valve directly can connect high-voltage tube, by the sewage draining exit effluent of valve body lower portion, by flashboard and the inner chamber of high-voltage tube hydro-peening gate valve, thus reach the object of interior cleaning; Make valve inner chamber when work clean, flashboard is card main valve seat tightly, plays good sealability.

Description

Cleaning type gate valve in a kind of high pressure
Technical field
The utility model relates to gate valve technical field, is specifically related to cleaning type gate valve in a kind of high pressure.
Background technique
Gate valve (gate valve) is main in pipeline plays cutting action.Flashboard is the critical component of gate valve, and moving direction and the flow direction of flashboard are perpendicular.Gate valve can make standard-sized sheet and complete shut-down, regulates and throttling use; But gate valve of the prior art, due to the reason of structural design, when the attachment of sealing surface generation greasy dirt, when flashboard produces other dirts, the sealability of sealing surface pair can be affected, be easy to produce and reveal, normally flashboard entirety is changed, cause the waste of cost.
Model utility content
The purpose of this utility model is to solve deficiency of the prior art, provides cleaning type gate valve in a kind of high pressure, can clean inner chamber, and keep clean, sealability improves.
For solving the problems of the technologies described above, the technological scheme that the utility model is taked is:, cleaning type gate valve in a kind of high pressure, comprise valve body, be installed on the valve gap of valve body upper shed, also comprise the small ball be arranged on valve gap and the sewage draining exit blocked with blowdown plug being arranged at valve body lower portion.
Also comprise and be arranged at spirotallic gasket between valve body and valve gap, and be connected with fastening nuts by stud bolt.
Be provided with valve rod in described valve gap, between valve rod lower end and valve body, be provided with flashboard.
Described valve rod upper end is provided with handwheel by Stem Mut, and is tightened together by locking nut.
Be provided with Packing seat, graphite packing between described valve gap and valve rod, graphite packing is provided with filler pressing sleeve, and is fastened together by hold-down grid, hexagon nut with flange and swing bolt and valve gap.
Be provided with bearing outside described Stem Mut, bearing is provided with bearing gland and lubricating cup, and bearing is fastenedly connected by lock screw and support.
Compared with prior art, the beneficial effects of the utility model are: the utility model product is when the attachment of sealing surface generation greasy dirt, when flashboard produces other dirts, the valve gap of its valve directly can connect high-voltage tube, by the sewage draining exit effluent of valve body lower portion, by flashboard and the inner chamber of high-voltage tube hydro-peening gate valve, thus reach the object of interior cleaning; Make valve inner chamber when work clean, flashboard is card main valve seat tightly, plays good sealability.
