Abstract
The utility model relates to the technical field of a valve, in particular to a novel butterfly plate interchanging and interworking three-eccentric butterfly valve. The butterfly valve is characterized by comprising a valve body, a valve rod, a butterfly plate sleeve, a butterfly plate screw, an intermediate fixed pin, a shaft seal, an oil-free bearing, a valve rod seal, a butterfly plate seal, two butterfly plate fixed keys, a butterfly plate, an oil-free bearing, a shaft seal, a valve seat screw and a valve seat. The two butterfly plate fixed keys are arranged on the butterfly plate, the butterfly plate seal is arranged on the butterfly plate, the butterfly plate seal selects hard seal or soft seal, and the butterfly plate is high in interchanging and interworking performance, simple in machining, high in applicability, and good in seal performance, so that the butterfly valve has the advantages of having high temperature-resistance, high press-resistance, corrosion-resistance, long service life and the like, is labor-saving in operation, and is flexible and reliable.
Description
[technical field]
The utility model relates to valve technology field, and especially a kind of novel butterfly plate exchanges joins three eccentric butterfly valve mutually.
[background technique]
The tradition butterfly valve is whole processing, and each valve can not be processed separately and can join mutually, like valve body and butterfly plate component, is to adopt the friction tight boring processing technology that closes, and it is high that it adds the required precision in man-hour, and sealing does not also usually reach effect; When valve opening and closing, not only butterfly plate very easily departs from, and causes the damage of seal ring itself easily.
[model utility content]
For addressing the above problem, the utility model provides a kind of novel butterfly plate exchange to join three eccentric butterfly valve mutually, and said a kind of novel butterfly plate exchanges joins three eccentric butterfly valve mutually; It is characterized in that, comprise valve body 1, valve rod 2, butterfly plate cover 3, butterfly plate screw 4, center fixed pin 5, shaft sealing 6, oilless bearing 17, valve stem seal 18, butterfly plate sealing 19, butterfly plate retainingf key 20, butterfly plate 21, oilless bearing 22, shaft sealing 23, valve seat screw 24, valve seat 25, said a kind of novel butterfly plate exchanges joins three eccentric butterfly valve mutually; Abolished traditional valve body and butterfly plate component (closing boring) processing technology, the component all to butterfly valve carry out single-piece work, the processes of whole assembling; Said a kind of novel butterfly plate exchanges joins three eccentric butterfly valve mutually, on butterfly plate, is provided with two butterfly plate retainingf keys 20, has abolished the positioning process of the original fixed cylinder pin that adopts of butterfly plate; Use double bond structure instead, be convenient to assembling, change and maintenance, said a kind of novel butterfly plate exchanges joins three eccentric butterfly valve mutually; On butterfly plate, be provided with butterfly plate sealing 19; Butterfly plate sealing 19 is selected hard sealing or soft seal according to the different medium operating mode, needs only and selects unlike material when changing the butterfly plate seal ring for use; Just can satisfy user's working condition of different medium; Said a kind of novel butterfly plate exchanges joins three eccentric butterfly valve mutually, and its butterfly plate 21 all adopts forging and heat treatment process with valve rod 2, has increased the mechanical property of material.
The utility model beneficial effect: 1. to exchange interaction strong for butterfly plate, if maintenance does not need the integral replacing valve, only valve plate changed, or changed sealing and get final product.2. processing is simple, and each valve parts can be processed separately also and can join mutually.3. applicability is strong, and good seal performance has high temperature resistant, high pressure, anticorrosive, characteristics, rapid operation, flexibility and reliability such as the life-span is long.
[description of drawings]
Fig. 1 is that the three eccentric butterfly valve general illustration is joined in a kind of novel butterfly plate exchange mutually;
[embodiment]
Below in conjunction with accompanying drawing and embodiment the utility model is described in detail:
Said a kind of novel butterfly plate exchanges joins three eccentric butterfly valve mutually, has abolished traditional valve body and butterfly plate component (closing boring) processing technology, and the component all to butterfly valve carry out single-piece work; The processes of whole assembling, said a kind of novel butterfly plate exchanges joins three eccentric butterfly valve mutually, on butterfly plate, is provided with two butterfly plate retainingf keys 20; Abolished the positioning process of the original fixed cylinder pin that adopts of butterfly plate, used double bond structure instead, be convenient to assembling, change and maintenance; Said a kind of novel butterfly plate exchanges joins three eccentric butterfly valve mutually, on butterfly plate, is provided with butterfly plate sealing 19, and butterfly plate sealing 19 is according to the different medium operating mode; Select hard sealing or soft seal; As long as select unlike material for use when changing the butterfly plate seal ring, just can satisfy user's working condition of different medium, said a kind of novel butterfly plate exchanges joins three eccentric butterfly valve mutually; Its butterfly plate 21 all adopts forging and heat treatment process with valve rod 2, has increased the mechanical property of material.
Claims (1)
1. a novel butterfly plate exchanges and joins three eccentric butterfly valve mutually; It is characterized in that; Comprise valve body, valve rod, butterfly plate cover, butterfly plate screw, center fixed pin, shaft sealing, oilless bearing, valve stem seal, butterfly plate sealing, butterfly plate retainingf key, butterfly plate, oilless bearing, shaft sealing, valve seat screw, valve seat; Said a kind of novel butterfly plate exchanges joins three eccentric butterfly valve mutually, on butterfly plate, is provided with two butterfly plate retainingf keys, and said a kind of novel butterfly plate exchanges joins three eccentric butterfly valve mutually; On butterfly plate, be provided with the butterfly plate sealing, hard sealing or soft seal are selected in the butterfly plate sealing.
