Abstract
The utility model discloses a novel telescopic ball valve and relates to the technical field of the valve. The novel telescopic ball valve comprises a left valve body and a right valve body. The left valve body is tightly connected with the right valve body through a fastening bolt. The left valve body is provided with a ball valve body. The novel telescopic ball valve is characterized in that the right side of the right valve body is also provided with a creeping flange; the creeping flange is fastened and connected with the right valve body through a connecting screw rod; all flow passing surfaces of the left valve body, the right valve body, the ball valve body and the creeping flange are respectively coated with a poly perfluoro propylene layer. The novel telescopic ball valve has the beneficial effects that the creeping flange is arranged at the right side of the right valve body, so that the excellent compensating performance of the whole valve body is realized; meanwhile, all the flow passing surfaces of the left valve body, the right valve body, the ball valve body and the creeping flange are coated with the poly perfluoro propylene layers, so that the ultra strong corrosion resistance of the whole valve body is also realized; and the novel telescopic ball valve not only has a simple and scientific structure, but also is durable.
Description
Technical field
The utility model relates to valve technology field, especially relates to a kind of novel telescopic ball valve with fluoroplastics lining structure.
Background technique
Under the working condition of many conveying active sulfur body mediums, metal valve obviously can't be realized long-term use owing to very easily be subjected to the corrosion of corrosive liquids; In addition, existing on the market at present ball valve, because structure is too single, no Telescopic can not regulation structure length during installation, thereby can't reach the requirement of compensation, the purchase compensation device has improved purchase cost in addition.
The model utility content
The utility model is in order to solve deficiency of the prior art, provides a kind of good seal performance, antiseptic property strong, and the novel telescopic ball valve of long service life.
The technical problem that the utility model solved realizes by the following technical solutions:
A kind of novel telescopic ball valve, comprise a left valve barrel and a right valve barrel, closely link to each other by a clamping bolt between described left valve barrel and the described right valve barrel, on described left valve barrel, be provided with a ball valve body, it is characterized in that: the right side at described right valve barrel also is provided with a creeping flange, described creeping flange connects screw mandrel by one and links to each other with described right valve barrel is fastening, all is coated with one deck polyfluorinated ethylene plastic layer on all flow-passing surfaces of described left valve barrel, right valve barrel, ball valve body and described creeping flange.
Also be provided with an annular packing in the slit between described right valve barrel and the described creeping flange, described annular packing also is sealed between described right valve barrel and the described creeping flange by a Gland.
The beneficial effects of the utility model are: by the right side at right valve barrel creeping flange is set, has realized the good compensation performance of whole valve body.Simultaneously, by on all flow-passing surfaces of left valve barrel, right valve barrel, ball valve body and creeping flange, all coating one deck perfluoroethylene-propylene layer, realized the superpower corrosion resistance of whole valve body again.Science not only simple in structure, and durable in use.
Description of drawings
Fig. 1 is the utility model: a kind of cross-sectional view of novel telescopic ball valve;
Fig. 2 is the utility model: the part section structural representation in a kind of novel telescopic ball valve between right valve barrel 2 and the creeping flange 5.
Embodiment
In order to make the utility model realize new technological means, creation characteristic, to reach purpose and effect is easy to understand,, further set forth the utility model below in conjunction with concrete diagram.
Shown in Fig. 1,2, a kind of novel telescopic ball valve comprises left valve barrel 1 and right valve barrel 2, wherein, closely links to each other by a clamping bolt 3 between left valve barrel 1 and the right valve barrel 2, is provided with a ball valve body 4 on left valve barrel 1.Also be provided with a creeping flange 5 on the right side of right valve barrel 2, creeping flange 5 connects screw mandrel 6 and 2 fastening linking to each other of right valve barrel by one, all is coated with one deck polyfluorinated ethylene plastic layer 7 on all flow-passing surfaces of left valve barrel 1, right valve barrel 2, ball valve body 4 and creeping flange 5.
Also be provided with an annular packing 8 in the slit between right valve barrel 2 and the creeping flange 5, annular packing 8 also is sealed between right valve barrel 2 and the creeping flange 5 by a Gland 9.
The utility model is provided with creeping flange by the right side at right valve barrel, has realized the good compensation performance of whole valve body.Simultaneously, by on all flow-passing surfaces of left valve barrel, right valve barrel, ball valve body and creeping flange, all coating one deck perfluoroethylene-propylene layer, realized the superpower corrosion resistance of whole valve body again.Science not only simple in structure, and durable in use.
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 (2)
