Abstract
The utility model discloses a marine stop valve and belongs to the technical field of valves. The marine stop valve comprises a valve body, a valve bonnet, a valve clack and a valve rod, wherein the valve rod passes through the valve bonnet, a first padding chamber is arranged between the valve bonnet and the valve rod, a first padding cover is fixedly arranged between the valve bonnet and the valve body, the valve rod penetrates through the padding cover, a second padding chamber is arranged between the padding cover and the valve rod, and the first padding chamber and the second padding chamber are filled with padding. The marine stop valve is stable in sealing performance, and safe and reliable in utilization, completely eradicates the phenomenon of medium leakage, successively solves the technical problems that a common valve is poor in sealing performance and prone to leakage, and is widely used in valve manufacture industry.
Description
Technical field
The utility model relates to valve technology field, relates in particular to a kind of stop valve peculiar to vessel.
Background technique
Existing stop valve peculiar to vessel comprises valve body at present, valve gap, flap, valve rod, Stuffing box, wherein valve body is provided with water intake and water outlet, be communicated with by the fluid passage mouth between water intake and the water outlet, valve body and valve gap are equipped with the inner chamber that valve rod is installed, valve stem slides is installed in body cavity and passes the valve gap inner chamber, the end of valve rod is equipped with to be sealed and matched with described fluid passage mouth and opens and closes the flap of described stop valve, in the using process, thereby the valve rod to-and-fro motion drives the flap motion, just realize also that flap and fluid passage mouth are sealed and matched and close stop valve, perhaps flap separates opening stop valve with the fluid passage mouth, and at present common valve only is provided with a Stuffing box at valve gap, poor sealing performance, easily leak, gap between valve rod periphery and its contacted each parts becomes main earial drainage place, and also therefore the stop valve that is sealed between the periphery of valve rod and its contacted each parts seals a maximum difficult problem.
The model utility content
Technical problem to be solved in the utility model is: provide a kind of stop valve peculiar to vessel, with the technical problem that solves the common valve poor sealing performance, easily leaks.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of stop valve peculiar to vessel, comprise valve body, valve gap, flap and valve rod, described valve rod passes described valve gap, be provided with the first filler chamber between described valve gap and the valve rod, be installed with a follower between described valve gap and the valve body, described valve rod runs through described follower, be provided with the second filler chamber between described follower and the valve rod, all be filled with filler in described the first filler chamber and the second filler chamber.
As a kind of preferred scheme, described valve rod be provided with one with the suitable boss of described second filler chamber's shape, described boss is between described follower and flap.
After having adopted technique scheme, effect of the present utility model is: owing to being provided with follower between valve gap and valve body, follower is provided with the second filler chamber, like this valve rod axially on just formed double-layer sealing structure, therefore, stop valve is in the course of the work, guaranteed that valve rod fully contacts with filler, by multi-sealed to the parts that contact with the valve rod outer circumferential face, improved sealing effect and the operational safety of stop valve, thoroughly stop the phenomenon that leaks outside of medium.
Because valve rod is provided with the suitable boss of one and second filler chamber's shape, when stop valve was opened fully, the filler of boss and the second filler chamber leant again, formed end face seal, therefore, increase again by a resealing, further improved sealing and the operational safety of stop valve.
Description of drawings
Accompanying drawing is the utility model embodiment's structural representation;
Among the figure: 1, valve body, 2, valve rod, 3, valve gap, the 4, first filler chamber, 5, follower, the 6, second filler chamber, 7, flap, 8, handwheel, 9, the fluid passage, 10, water outlet, 11, water intake, 12, boss.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in drawings, a kind of stop valve peculiar to vessel, comprise valve body 1, valve gap 3, flap 7 and valve rod 2, valve body 1 is provided with water intake 11 and water outlet 10, be communicated with by fluid passage 9 between water intake 11 and the water outlet 10, valve gap 3 is installed on the valve body 1, valve rod 2 passes valve gap 3, be provided with the first filler chamber 4 between valve gap 3 and the valve rod 2, be installed with a follower 5 between valve gap 3 and the valve body 1, valve rod 2 runs through follower 5, is provided with 6, the first filler chamber 4 of the second filler chamber and the second filler chamber 6 interior fillers that all are filled with between follower 5 and the valve rod 2.
Valve rod 2 is provided with the suitable boss 12 of the one and second filler chamber 6 shapes, and boss 12 is between follower 5 and flap 7.
During work, rotate handwheel 8, because handwheel 8 is fixed as one with valve rod 2, valve rod 2 is in the process of rotating and move up, valve rod 2 fully contacts with filler, by multi-sealed to the parts that contact with valve rod 2 outer circumferential faces, has guaranteed the sealing of valve rod 2 in moving process, when stop valve is opened fully, namely valve rod 2 moves to highest position, and the filler of boss 12 and the second filler chamber 6 leans, and has formed end face seal, form reliable static seal, guaranteed the positive confinement of stop valve.
The utility model is not limited to above-mentioned concrete mode of execution, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done all drop within the protection domain of the present utility model.
Claims (2)
1. stop valve peculiar to vessel, comprise valve body, valve gap, flap and valve rod, described valve rod passes described valve gap, be provided with the first filler chamber between described valve gap and the valve rod, it is characterized in that: be installed with a follower between described valve gap and the valve body, described valve rod runs through described follower, is provided with the second filler chamber between described follower and the valve rod, all is filled with filler in described the first filler chamber and the second filler chamber.
