Background technique
In fields such as oil, chemical industry, rock gas, power plant, iron and steel, colliery, sewage treatments, gate valve is used in the capital, traditional gate valve mostly is top Wedge gate valve, plate valve, butterfly valve etc., but all there is following defective in these traditional gate valves: because filter not to the utmost in the pipeline or the various impurity that carry over (as sand grains, iron wire, welding rod, thin round steel, fiber etc.) cause damage to the valve seal pair, or viscosity fouling medium causes the phenomenon of the not tight and interior leakage of valve closing; Because of temperature variation is very big, and flashboard is stuck and the phenomenon of not opening.
The model utility content
At the defective of existing gate valve, the utility model provides a kind of coupling to move gate valve.
To achieve these goals, technical solution adopted in the utility model is:
A kind of coupling moves gate valve, comprise valve body, the lower end of valve body is provided with valve seat, valve plate adds by contiguous block to be put chapiter screw and links to each other with the valve plate core, the valve plate core is provided with the flashboard positioning ring, the top of flashboard positioning ring is connected with spring and spool regulating block in turn, the valve plate core links to each other with handwheel by valve rod, the top of valve seat is connected with valve gap, be provided with middle flange gasket between valve seat and the valve gap, the valve gap internal fixation has upper seal support, and the adjusting bolt that an end is fixed on the valve gap links to each other with hold-down grid, the below of hold-down grid is connected with the filler gland, is provided with filler between upper seal support and the filler gland;
Built-up welding has the anti-corrosive alloy material of high hardness on the sealing surface of gate valve;
Described valve seat links to each other with the valve gap bolt by bonnet nut with valve gap;
Described adjusting bolt links to each other with hexagon nut by the pressing plate pad with hold-down grid;
Described valve rod links to each other with screw by Stem Mut with handwheel;
Described valve rod is provided with forced filling oil cup, and the forced filling oil cup top is provided with gland;
Described filler is an Expanded graphite.
The beneficial effects of the utility model: because of valve plate inside is provided with the slow automatically device of opening, guarantee that valve is in coupling (motive sealing) state all the time in opening-closing process under the effect in the internal mechanism, and can cut off the metal or the fiber impurity of strip, get rid of granular or resisting medium and do not damage sealing pair, thereby make valve have extremely strong sealing, also can not produce any influence to sealing surface even have granular dirt in the pipeline medium; Sealing pair adopts special material and does special processing, can thoroughly scrape the various dirts that stick on to the greatest extent on the sealing surface, the energy automatic pollutant removal, the wearing and tearing of energy automatic compensation sealing pair have overcome conventional valves because of the problem that viscosity fouling medium causes valve leak often to overhaul, and have saved cost, improved usefulness, switch is flexible, and is easily laborsaving, long service life.
