Abstract
The utility model relates to a highly wear-resistant butterfly valve, which belongs to a butterfly valve and comprises a valve body, a valve rod, a butterfly plate, a valve seat and a driving device; wherein the butterfly plate is installed on the valve body through the valve rod, the valve rod is connected with the driving device, and the valve seat is fixed in the groove of the valve body through a compressing plate. The highly wear-resistant butterfly valve is characterized in that a wear-resistant sleeve is also arranged in the groove of the valve body, and a butterfly plate current plate and a butterfly plate fuisw rib are also produced on the butterfly plate. The highly wear-resistant butterfly valve has the advantages that the wear-resistant sleeve is additionally installed in the groove of the valve body and outside the valve seat, and the current plate and the fuisw rib are produced on the butterfly plate, so that the valve seat is protected, the flush of impurity in the fluid medium is reduced when the butterfly plate is in a small opening state, and the service life of the butterfly valve is prolonged.
Description
Technical field
The utility model relates to butterfly valve, specifically is a kind of high abrasion butterfly valve.
Background technique
Butterfly valve is Flap valve again, and (English: butterfly valve) be meant that closure member (flap or butterfly plate) is a disk, rotate a kind of valve that reaches open and close around valve shaft, main rising cut off and throttling usefulness on pipeline.The butterfly valve open-shut device is a discoidal butterfly plate, and the axis around himself in valve body rotates, thereby reaches the purpose that opens and closes or regulate.Normally less than 90 °, butterfly valve and butterfly bar itself do not have self-lock ability to the butterfly valve standard-sized sheet to complete shut-down, for the location of butterfly plate, install worm speed reducer additional on valve rod.Adopt worm speed reducer, not only can make butterfly plate have self-lock ability, butterfly plate is stopped on the arbitrary position, can also improve the operating characteristics of valve.And butterfly valve is when carrying flowing medium of different nature, the material that often contains various easy precipitations in the flowing medium, easily valve seat is produced the wear particle thing, therefore in use, valve is when closing, and the particulate matter that is also easily accumulated between valve seat and the valve body stops and valve seat is in the defective of erosive wear state all the time.
The model utility content
The technical problem that the utility model solved is to provide a kind of protection valve plate, alleviates the high abrasion butterfly valve that washes away valve seat.
The technical problem that the utility model solved realizes by the following technical solutions:
A kind of high abrasion butterfly valve, constitute by valve body, valve rod, butterfly plate, valve seat and drive unit, butterfly plate is installed on the valve body by valve rod, valve rod is connected with drive unit, valve seat is fixed in the groove of valve body by pressing plate, it is characterized in that: also be provided with wear-resistant sleeve in the groove of described valve body, on described butterfly plate, also be shaped on butterfly plate dumping-guiding plate and butterfly plate guide rib.
Described butterfly plate guide rib is built in the back side of butterfly plate, when being used for fluid medium by butterfly plate, and the shunting of slowing down.
Described butterfly plate dumping-guiding plate, carries out drainage and alleviates washing away valve seat when being used for fluid medium by butterfly plate built in the front of butterfly plate.
The inflow end of described butterfly valve flowing medium is also installed a wear-resistant pipe nipple, and described wear-resistant pipe nipple and valve body join by bolt, when being used to protect the butterfly plate standard-sized sheet, alleviate wearing and tearing.
The beneficial effects of the utility model are outside valve seat; install wear-resistant sleeve additional in the groove between the valve body, on butterfly plate, be shaped on dumping-guiding plate and guide rib, protected valve seat like this at the little aperture state of butterfly plate; the impurity that alleviates in the flowing medium washes away, and has prolonged the working life of butterfly valve.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of high abrasion butterfly valve, constitute by valve body 1, valve rod 2, butterfly plate 3, valve seat 4 and drive unit 5, butterfly plate 3 is installed on the valve body 1 by valve rod 2, the top of valve rod 2 and drive unit 4 join, valve seat 4 is installed in the groove of valve body 1, and wherein wear-resistant sleeve 6 is also installed in the outside of valve seat 4 in the groove of valve body 1.Be shaped on butterfly plate dumping-guiding plate 7 on the front of butterfly plate 3, the back side of butterfly plate 3 is shaped on butterfly plate guide rib 8, and when being used for flowing medium by butterfly valve, and butterfly plate is in little aperture state, and fluid medium is slowed down and shunted and protection valve seat 4, alleviates and washes away.
After butterfly valve installed, a wear-resistant pipe nipple 9 was also installed at the inflow end place of the flowing medium of butterfly valve, is bolted to connection between the outer rim of wear-resistant pipe nipple 9 and the valve body 1, was used for alleviating the wearing and tearing to butterfly plate 3 edges when butterfly plate 3 standard-sized sheets.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (4)
1. high abrasion butterfly valve, constitute by valve body, valve rod, butterfly plate, valve seat and drive unit, butterfly plate is installed on the valve body by valve rod, valve rod is connected with drive unit, valve seat is fixed in the groove of valve body by pressing plate, it is characterized in that: also be provided with wear-resistant sleeve in the groove of described valve body, on described butterfly plate, also be shaped on butterfly plate dumping-guiding plate and butterfly plate guide rib.
