Description

The dark bar soft sealing gate valve of integral type valve gap
Technical field
The utility model relates to the dark bar soft sealing gate valve of a kind of dark bar soft sealing gate valve, especially integral type valve gap.
Background technique
Dark bar soft sealing gate valve is widely used on the pipeline of industries such as oil, chemical industry, pharmacy, metallurgy, coal, power industry, urban water supply and sewerage, and be used for the circulation of pilot line medium and block, be one of most widely used valve in the various fluid conveying engineerings.Be applicable to multiple media such as sewage, Yuan Shui, clear water, oil product, be not subjected to MEDIA FLOW to restriction.The leakage of dark bar soft sealing gate valve is to need the problem that solves for a long time always, in order to address this problem the sealing that then will guarantee gate valve.The sealing of dark bar soft sealing gate valve commonly used is divided into the sealing between sealing, valve gap and the valve rod between sealing, valve plate and the valve gap between valve plate and the valve body, and the sealing of valve gap and valve rod is called sealing.The sealing of going up of existing this dark bar soft sealing gate valve is finished by the axle joint sealing, because axle joint sealing fastening piece is many, so processing technology, component material and assembly precision are bigger to the sealing effect influence of axle joint sealing, in case machining accuracy is not high, the axle joint sealing will leak, thereby causes waste.
The model utility content
The purpose of this utility model is to solve the sealing effect that seals on the existing dark bar soft sealing gate valve to be subjected to machining accuracy to influence bigger problem.
The technical solution adopted in the utility model is: the dark bar soft sealing gate valve of integral type valve gap, comprise valve rod, valve gap, be provided with the dust ring, lining, thrust bearing, the rubber seal that are socketed on successively on the valve rod in the described valve gap, described sleeve outer surface is connected with the outer O type circle of lining, be provided with O type circle in the lining that is socketed on the valve rod between described lining and the valve rod, the lower surface of described thrust bearing is provided with triangular groove.
As further improvement of the utility model, interference fit between described thrust bearing and the valve gap.
As further improvement of the utility model, the outer O type circle of described lining has two, and O type circle has two in the described lining.
The beneficial effect that the utility model adopts is: after having adopted this structure, sealingly secure does not reliably have leakage between this dark bar soft sealing gate valve valve gap and the valve rod, machining accuracy is low, component are few, cost of production is low.
Description of drawings
Fig. 1 is the utility model schematic representation.
Fig. 2 is the enlarged view at A place among Fig. 1.
Shown in the figure: 1, handwheel, 2, the handwheel pressing plate, 3, the handwheel clamping bolt, 4, valve rod, 5, valve gap, 6, dust ring, 7, the outer O type circle of lining, 8, O type circle in the lining, 9, lining, 10, thrust bearing, 11, triangular groove, 12, rubber seal, 13, hot melt seals with wax, 14, valve gap bolt, 15, the valve gap packing ring, 16, valve body, 17, valve plate nut, 18, valve plate.
Embodiment
Below in conjunction with Fig. 1,2, the utility model is described further.
As shown in Figure 1, 2, the dark bar soft sealing gate valve of integral type valve gap, comprise valve rod 4, valve gap 5, it is characterized in that being provided with in the described valve gap 5 dust ring 6, lining 9, thrust bearing 10, the rubber seal 12 that is socketed on successively on the valve rod 4, described lining 9 outer surfaces are connected with the outer O type circle 7 of lining, be provided with O type circle 8 in the lining that is socketed on the valve rod 4 between described lining 9 and the valve rod 4,10 lower surfaces of described thrust bearing are provided with triangular groove 11.
Dark bar soft sealing gate valve in the utility model comprises in the outer O type circle 7 of handwheel 1, handwheel pressing plate 2, handwheel clamping bolt 3, valve rod 4, valve gap 5, dust ring 6, lining, the lining that O type circle 8, lining 9, thrust bearing 10, triangular groove 11, rubber seal 12, hot melt seal with wax 13, valve gap bolt 14, valve gap packing ring 15, valve body 16, valve plate nut 17, valve plate 18.The utility model has adopted the integral type valve cover structure in design, assemble sequence is: the dust ring 6 of packing in valve gap 5 upper ends, to there be the lining 9 of the outer O type circle 7 of two linings to pack in the valve gap 5, thrust bearing 10 is stuck on the valve rod 4 and with O type circle 8 in two linings is socketed on the valve rod 4, valve rod 4 is passed dust ring 6, going into triangular groove 11 with special tool Figure, thrust bearing 10 Figure of dovetail portion are gone into valve gap 5(thrust bearing 10 is to adopt copper production, has good ductility), be inserted in rubber seal 12 again, this has just finished the assembling of last sealing, this upward the sealing configuration component are few, and cost of production is low.
In order to make the sealingly secure between valve gap and the valve rod reliably not have leakage, simultaneously add needed precision in man-hour in order to reduce, in the utility model, lining 9 adopts the floating bush structure, the lining 9 inner interior O type circle 8 of two linings and the valve rods 4 of adopting seal, the lining 9 outside outer O type circle 7 of two linings and the valve gaps 5 of adopting seal, the top of last sealing is provided with dust ring 6, dust ring 6 is positioned at the top of lining 9, thrust bearing 10 is positioned at the below of lining 9, the bottom of last sealing adopts rubber seal 12 to seal, rubber seal 12 is positioned at the below of thrust bearing 10, this sealing utilizes the elasticity of O type circle well, well seals by floating bush, thereby has reduced the machining accuracy of valve gap 5 with valve rod 4.
In sum, adopted this structure after, sealingly secure does not reliably have leakage between this dark bar soft sealing gate valve valve gap and the valve rod, machining accuracy is low, component are few, cost of production is low.
