Description
Technical Field
The utility model relates to a chemical industry equipment especially relates to a sealed lid of pressure vessel.
Background
The pressure container is a closed device which contains gas or liquid and bears certain pressure. The opening of the pressure vessel is usually closed with a sealing lid. However, the sealing cap in the prior art cannot ensure a sealing effect, and when the pressure in the container increases, a gap between the sealing cap and the opening of the pressure container increases, thereby causing leakage.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that overcome exist among the prior art not enough, provide a sealed lid of pressure vessel, can improve the sealed effect of sealed lid.
The utility model discloses a realize through following technical scheme:
the utility model provides a pressure vessel sealing cover, includes apron and buckle, the apron is the circular slab, the apron is equipped with a plurality of mounting holes, the buckle is the pipe form, a plane of apron and an open end body coupling of buckle, the outside of buckle is equipped with the ring channel, install the sealing washer in the ring channel, another open end of buckle is equipped with the rubber membrane, the rubber membrane bonds the bullet piece, the bullet piece is located inside the buckle, the one end of a plurality of connecting rods is articulated to the bullet piece, the articulated ejector pad of the other end of connecting rod, the lateral wall of buckle is equipped with a plurality of through-holes, the ejector pad passes through-hole and butt sealing washer.
According to the technical scheme, preferably, a groove is formed in the annular groove and is communicated with the through hole, and the shape, the number and the position of the groove are matched with those of the push block.
According to the technical scheme, preferably, a spring is arranged between the cover plate and the elastic block.
The utility model has the advantages that: when the pressure in the pressure container is increased, the sealing ring can be attached to the pressure container more tightly, so that the sealing effect of the sealing cover is improved.
Drawings
Fig. 1 shows a schematic cross-sectional structure diagram of an embodiment of the present invention.
Fig. 2 shows an internal structural schematic diagram of an embodiment of the present invention.
In the figure: 1. the rubber sealing device comprises a cover plate, 2 parts of retaining rings, 3 parts of mounting holes, 4 parts of annular grooves, 5 parts of sealing rings, 6 parts of rubber films, 7 parts of elastic blocks, 8 parts of connecting rods and 9 parts of push blocks.
Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.
As shown in the figure, the utility model relates to a pressure vessel seals lid, including apron 1 and buckle 2, the apron is the circular slab, the apron is equipped with a plurality of mounting holes 3, the buckle is the pipe form, a plane of apron and an open end body coupling of buckle, the outside of buckle is equipped with ring channel 4, erection joint circle 5 in the ring channel, another open end of buckle is equipped with rubber membrane 6, rubber membrane bonding elastic block 7, the elastic block is located inside the buckle, the articulated one end of a plurality of connecting rods 8 of elastic block, the articulated ejector pad 9 of the other end of connecting rod, the lateral wall of buckle is equipped with a plurality of through-holes, the ejector pad passes through-hole and butt sealing washer.
In this embodiment, the cover plate covers the opening of the pressure vessel and is connected to the pressure vessel by installing bolts in the mounting holes. The retaining ring is abutted against the inner wall of the opening of the pressure container, so that the sealing cover is limited, and the sealing cover is prevented from shaking. When pressure in the pressure vessel increases, can make the rubber membrane receive tension deformation, the rubber membrane can promote the bullet piece and remove, and the bullet piece removes and can drive the ejector pad through the connecting rod and remove, and the ejector pad can promote the outside expansion of sealing washer, makes the lateral wall butt of sealing washer and pressure vessel inseparabler.
According to the technical scheme, preferably, a groove is formed in the annular groove and is communicated with the through hole, and the shape, the number and the position of the groove are matched with those of the push block. The groove in the embodiment facilitates installation of the push block.
According to the technical scheme, preferably, a spring is arranged between the cover plate and the elastic block. The spring can improve the elasticity that resets of bullet piece and rubber membrane.
The utility model has the advantages that: when the pressure in the pressure container is increased, the sealing ring can be attached to the pressure container more tightly, so that the sealing effect of the sealing cover is improved.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
