Abstract
The utility model belongs to the technical field of the head technique and specifically relates to a telescopic toper head is related to, including closing cap, middle expansion plate and closing cap bottom plate, the closing cap is an upper end and seals, lower extreme open-ended toper structure, middle expansion plate and closing cap bottom plate are upper and lower open-ended round platform structure, in the expansion plate was fitted in the middle to the closing cap lower extreme cover, middle expansion plate upper end internal diameter was less than closing cap lower extreme external diameter, middle expansion plate overlaps and closes in the closing cap bottom plate, closing cap bottom plate upper end internal diameter is less than middle expansion plate lower extreme external diameter. The utility model discloses a mode that the multistage combines even pressure is too big in the container, also can reach the effect that expands inner space and reduce pressure through the extension of head. The utility model discloses when not using, can shrink this toper head in order to reach the purpose in space-saving.
Description
Technical Field
The utility model belongs to the technical field of the head technique and specifically relates to a telescopic toper head is related to.
Background
The seal head is often used as the both sides end cover of some pressure vessel, and the pressure is great in the pressure vessel generally, and the rigidity intensity is great generally with the material that the seal head adopted for pressure vessel, is difficult for taking place the deformation to lead to pressure vessel internal pressure too big and take place danger such as explosion or reveal, influence production transportation safety.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a telescopic toper head.
In order to solve the technical problem, the utility model discloses a technical scheme as follows: the utility model provides a telescopic toper head, includes closing cap, middle expansion plate and closing cap bottom plate, the closing cap is that an upper end seals, lower extreme open-ended toper structure, middle expansion plate and closing cap bottom plate are upper and lower open-ended round platform structure, in the expansion plate was fitted in to closing cap lower extreme cover, middle expansion plate upper end internal diameter was less than closing cap lower extreme external diameter, middle expansion plate overlaps in the closing cap bottom plate, closing cap bottom plate upper end internal diameter is less than middle expansion plate lower extreme external diameter.
Furthermore, the periphery of the sealing cover is fixedly provided with a fluororubber sleeve, and the other end of the fluororubber sleeve is fixedly connected to the periphery of the sealing cover bottom plate.
Furthermore, a sealing rubber strip is sleeved at the connecting position of the fluororubber sleeve, the sealing cover and the sealing cover bottom plate.
To sum up, the utility model discloses compare in the beneficial effect of traditional technical means and be:
1. the utility model discloses a mode that the multistage combines even pressure is too big in the container, also can reach the effect that expands inner space and reduce pressure through the extension of head.
2. The utility model discloses when not using, can shrink this toper head in order to reach the purpose in space-saving.
3. The utility model discloses the outside adopts the fluororubber cover parcel, can guarantee that the fluid can not reveal in the pressure vessel, and fluororubber corrosion resisting ability is strong moreover, and mechanical properties is good.
Drawings
The foregoing and other objects, features, and advantages of the invention will be apparent from the following detailed description taken in conjunction with the accompanying drawings.
Fig. 1 is a schematic structural diagram of the present invention.
Wherein: 1. the sealing cover comprises a sealing cover, 2, a middle expansion plate, 3, a sealing cover bottom plate, 4, a fluororubber sleeve and 5, a sealing rubber strip.
Detailed Description
In the following, the preferred embodiments of the present invention will be explained, and various changes and modifications can be made by workers without departing from the technical spirit of the present invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
The invention will be further described with reference to the following description of the drawings: the utility model provides a telescopic toper head, includes closing cap 1, middle expansion plate 2 and closing cap bottom plate 3, closing cap 1 seals for an upper end, lower extreme open-ended toper structure, middle expansion plate 2 and closing cap bottom plate 3 are upper and lower open-ended round platform structure, 1 lower extreme registrates in middle expansion plate 2 of closing cap, 2 upper end internal diameters of middle expansion plate are less than 1 lower extreme external diameters of closing cap, 2 registrates in closing cap bottom plate 3 of middle expansion plate, 3 upper end internal diameters of closing cap bottom plate are less than 2 lower extreme external diameters of middle expansion plate. The periphery of the sealing cover 1 is fixedly provided with a fluororubber sleeve 4, and the other end of the fluororubber sleeve 4 is fixedly connected to the periphery of the sealing cover bottom plate 3. And sealing rubber strips 5 are sleeved at the connecting positions of the fluororubber sleeve 4, the sealing cover 1 and the sealing cover bottom plate 3.
In the telescopic conical end socket, the inner diameter of the upper end of the middle telescopic plate 2 is smaller than the outer diameter of the lower end of the sealing cover 1; the inner diameter of the upper end of the seal cover bottom plate 3 is smaller than the outer diameter of the lower end of the middle expansion plate 2, so that the seal cover 1, the middle expansion plate 2 and the seal cover bottom plate 3 cannot be separated when being extended, and certain expansion capacity is achieved. And the fluororubber sleeves 4 arranged outside the sealing cover 1 and the sealing cover bottom plate 3 can effectively prevent gas or liquid in the pressure container from flowing out.
