Description
Technical field
The utility model relates to a kind of butterfly valve, specifically, is a kind of dress formula butterfly valve of going up.
Background technique
Three eccentric butterfly valve is widely used in pure pipeline and industry environmental protection water treatments such as food, beverage, medicine, chemical industry, and the tall building water-feeding ﹠ drainaging pipeline does to open and close or regulate the rate-of flow effect.Because the structural characteristics of butterfly valve has determined that butterfly valve butterfly plate sealing pair is an easily damaged parts, when butterfly valve was in the full open state, butterfly plate vertically stood in the pipeline, and the butterfly plate sealing pair is washed away by medium, and is fragile; When in the medium impurity being arranged, between butterfly plate sealing pair and the valve seal pair during mutual extrusion, the butterfly plate sealing pair is fragile (because of being three eccentric valves, the butterfly plate sealing pair is to do an oscillating motion with respect to the valve seal pair, be that butterfly plate is when valve is about to close, rapidly by the upper valve body sealing pair, and more by tight more).The damage of sealing pair must cause the valve seal performance decrease, the maintenance of valve put naturally user and production manufacturer in face of.Have only during usual maintenance valve is removed from pipeline, or (heavy caliber) severs the work that pipeline on the pipeline is finished maintenance.Bring very large workload to the maintenance man, also brought the inconvenience of routine work and loss economically for the user.
Therefore known three eccentric butterfly valve exists above-mentioned all inconvenience and problem.
Summary of the invention
The purpose of this utility model is to propose a kind of removable seal pair, can carry out the last dress formula butterfly valve of on-line maintenance.
For achieving the above object, technical solution of the present utility model is:
A kind of dress formula butterfly valve of going up comprises a valve gap, a valve body, and a valve rod and a butterfly plate is characterized in that:
Described valve gap, an end face is connected with a valve body, and the other end is connected with a support;
Described valve body, two end part can be connected with pipeline, and the upper-end surface is connected with described valve gap, and the lower end is provided with a valve rod hole, and is provided with a butterfly plate in lumen, and described butterfly plate can be around valve rod rotation;
Described valve rod, an end passes the axis hole of described valve gap, links into an integrated entity with described butterfly plate in the body cavity, and the other end is connected with drive unit;
Described butterfly plate and is installed in the common big Sealing of forming of sealing pair on the described butterfly plate and pressing plate, and described butterfly plate is connected with valve rod by taper pin, and can to wind with the valve rod at body cavity be that the center rotates freely, so that valve opening and closing;
Wherein, described valve gap and valve body are by stud, and nut and plain washer link together.
The dress formula butterfly valve of going up of the present utility model can also be further achieved by the following technical measures.
The aforesaid dress formula butterfly valve of going up, wherein said valve gap and valve rod, butterfly plate, pressing plate, seal ring, upper press cover, support, last lining, drive unit are provided with in aggregates, described integral body can be that the center is rotated counterclockwise 90 ° or 180 ° with the valve rod, and can extract out from the upper end-hole of described valve body by lifting bolt, so that valve body and valve gap are in separated state.
The aforesaid dress formula butterfly valve of going up, wherein said butterfly plate and pressing plate link together by socket head screw.
After adopting technique scheme, the dress formula butterfly valve of going up of the present utility model has the following advantages:
1. pipeline need not be removed, cut off to the butterfly valve maintenance from pipeline.
2. easy to maintenance quick, significantly reduce maintenance cost.
Description of drawings
Fig. 1 is the dress formula butterfly valve structural representation under full-gear of going up of the present utility model.
Fig. 2 is the dress formula butterfly valve structural representation under the complete shut-down state of going up of the present utility model.
Wherein: 1 bottom, 2 sealing gaskets, 3 adjust piece, 4 valve bodies, 5 times linings, 6 seal rings, 7 taper pins, 8 butterfly plates, 9 valve rods, 10 pressing plates, lining on 11,12 gasket seals, 13 fillers, 14 valve gaps, 15 supports, 16 upper press covers, 17 flat keys, 18 socket head screws, 19 socket head screws, 20 nuts, 21 stud, 22 plain washers, 23 lifting bolts, 24 bolts, 25 spring washers, 26 stud, 27 nuts, 28 plain washers, 29 bolts, 30 spring washers, 31 drive units, 32 taper pins.
Embodiment
Below in conjunction with embodiment and accompanying drawing thereof the utility model is illustrated further.
Now see also Fig. 1 and Fig. 2, Fig. 1 is the dress formula butterfly valve structural representation under full-gear of going up of the present utility model, and Fig. 2 is the dress formula butterfly valve structural representation under the complete shut-down state of going up of the present utility model.As shown in the figure, described valve body 4 passes through stud 21 with valve gap 14, nut 20, plain washer 22 links together, when needing, the stud 21 of dismantling, nut 20, plain washer 22, setting circle taper pin 32, make valve body 4 and valve gap 14 be in separated state, then valve gap 14, valve rod 9, butterfly plate 8, pressing plate 10, seal ring 6, upper press cover 16, support 15, last lining 11, it is that the center is rotated counterclockwise 90 ° or 180 ° that drive unit 31 grades are done as a whole winding with valve rod 9, by lifting bolt 23 this integral body is extracted out from the upper end-hole of valve body 4, that dismantles pressing plate 10 and butterfly plate 8 is connected socket head screw 19, repairs seal ring 6.After seal ring 6 is fixed, by opposite program valve is reduced, repair work promptly comes to an end, thereby truly accomplishes on-the-spot on-line maintenance, need not dismantle pipeline, cuts off pipeline.
