Description
Technical field
The utility model relates to a kind of gas pipe line control gear, relates in particular to a kind of coal gas diffusion clock valve.
Background technique
The diffusion clock valve of prior art, mostly be spherical clock valve or hemisphere clock valve, the rubbing contact of closing ball valve in the valve normally and tube wall of clock valve is closed, this wear-resisting property to ball valve and tube wall requires very high, if long-term use will certainly produce the gas leakage situation for a long time owing to rubbing, Safety performance is not high.Such diffusion clock valve Heavy Weight is also big with the iron amount in addition, is unfavorable for saving production cost.
Summary of the invention
The purpose of this utility model provides a kind of coal gas diffusion clock valve, and this valve arrangement is simple, Safety performance is high, cost of production is low.
The technical solution adopted in the utility model is:
Coal gas diffusion clock valve, comprise valve body, valve gap and seal, described valve body one side and pipeline are connected, the valve body downside is connected by taking over pipeline, valve body top is fixed with valve gap, and described seal comprises packing holder, is fixed on seal ring and pull bar on the packing holder, and described pull bar one end is fixed on the packing holder, the other end is by being located at the draw-bar seat of valve gap central authorities, and hinged with the flex point of the joint of pull bar and lever; Described seal ring contacts when closing with valve outlet tube wall port; Described valve gap next door is provided with rocking bar core, and described rocking bar core and rocking bar lower end are hinged, and the rocking bar upper end is hinged with lever one end; Described valve body downside is taken over the side and is provided with cylinder block, and described cylinder block and cylinder lower end are hinged, and described cylinder upper end is hinged by the piston rod and the lever the other end.
Described seal ring is a flexible seal ring, and described flexible seal ring is located in the circular groove of packing holder downside, and inboard embedding of described circular groove has cambridge ring, and described cambridge ring and flexible seal ring are fixed by nut by the trim ring of downside.
The inboard that described draw-bar seat contacts with pull bar is provided with O-ring seal.
The valve outlet tube wall port of flexible seal ring of the present utility model and rigidity is Elastic Contact when closing, close the back and produce certain air pressure in the valve body because the coal gas of pipeline passes straight through to, just the valve outlet tube wall port of flexible seal ring with rigidity has been pressed in closely after packing holder is stressed, coal gas just can not revealed away.Described seal ring is a flexible seal ring, described flexible seal ring is located in the circular groove of packing holder downside, the inboard embedding of described circular groove has cambridge ring, described cambridge ring and flexible seal ring are fixed by nut by the trim ring of downside, and said structure is fixed on the packing holder seal ring closely.The inboard that described draw-bar seat contacts with pull bar is provided with O-ring seal, when this structure is avoided pull bar occurring and is moved in draw-bar seat coal gas by the gap leak out may.
In the time will opening, the cylinder ventilation, piston rod up moves, because an end of piston rod and lever is hinged, the flex point of lever and the joint of pull bar are hinged, the lever the other end and rocking bar are hinged, rocking bar and rocking bar core are hinged, cylinder is hinged with cylinder block again, altogether five are articulated and connected and make piston rod drive lever one end to move upward, and lever drives pull bar by flex point and moves upward, the lever the other end and corresponding the rotating of rocking bar that is hinged on the rocking bar core, thereby finally make packing holder move up to the valve gap lower end and stop, thereby coal gas enters in other pipeline by the adapter of valve body unblockedly along with pull bar.In the time will closing, the gas motion of cylinder moves down piston rod, and it is downward that piston rod drives lever, the lever drives pull bar is downward, the packing holder that pull bar is fixed on the pull bar downwards down moves, and closely contacts with valve outlet tube wall port, thereby finishes closing motion.
The utility model has the advantages that pneumatic structure drives the packing holder of valve body and makes unlatching, closing movement up and down, has made full use of the pressure of coal gas, good sealing effect is simple in structure, the Safety performance height, and cost of production is low.
