Abstract
The utility model relates to a composite sealing piece, pertaining to a kind of sealing piece, which comprises a cylindrical sealing piece and a frustum sealing piece, wherein a cylindrical and a frustum through holes are opened in the middle of the cylindrical sealing piece, and the frustum sealing piece is opened with a cylindrical through hole; the frustum sealing piece is inlaid in the frustum through hole of the cylindrical sealing piece, coordinated in an interfering manner. Pursuant to convenience during installation works, oblique slits can be opened on the cylinder of the cylindrical sealing piece and on the cone of the frustum sealing piece. The utility model has the advantages of: convenient installation and disassembling, realization of automatic abrasion compensation, as well as strong sealing capabilities in severe environments.
Description
The utility model relates to composite seal spare, belongs to a kind of in the Sealing.
In present pipe fitting sealing, normally used rubber seal is a monomer, cylindrical, in installing and dismantling, there are many inconveniences, and, along with the relative friction between working environment and parts, sealing part abrasion is serious, and often Sealing one place breakage promptly causes scrapping of whole Sealing.
The purpose of this utility model provides a kind of composite seal spare, improves the sealability of Sealing under rugged environment, the convenient installation and dismounting, and composite seal spare has the automatic regulatory function of wearing and tearing.
The technical solution of the utility model is: composite seal spare is made up of cylinder seal and frustum formula Sealing, cylinder seal is an axle with its medial axis, that middle upper portion has is cylindrical, the bottom then has the taper type through hole, frustum formula Sealing is an axle with its medial axis, the centre has cylindrical hole, the taper type through hole coupling of frustum formula Sealing and cylinder seal, frustum formula Sealing is embedded in the taper type through hole of cylinder seal, and the two cooperates in the interference mode.
The frustum of above-mentioned frustum formula Sealing is tall and big in the cylinder height of cylinder seal, makes the end face of frustum formula Sealing exceed the end face of cylinder seal, and it is poor to form certain height between the two.
On the cylinder of above-mentioned cylinder seal, can crack according to oblique the having of needs easy for installation on the cone of frustum formula Sealing.
Crack and the cracking of frustum formula Sealing of above-mentioned cylinder seal can not be in a side in installation, preferably be positioned at the both sides of medial axis, become 180 degree for best.
The oblique face that cracks of above-mentioned cylinder seal, frustum formula Sealing is the 40-50 degree with the best angle that the bottom surface became separately.
The utility model has the advantages that: 1. have on the cylinder seal of composite seal spare, the frustum formula Sealing and crack, be easy for installation and removal, especially at arctic weather, under the situation of rubber because of the low temperature hardening; 2. cylinder seal, frustum formula Sealing cooperate in the interference mode, when the contact surface abrasion of cylinder seal and frustum formula Sealing, under the pressure outside effect that applies when mounted, frustum formula Sealing moves inward automatically, realizes the wear automatic-compensation function; 3. facts have proved that under rugged environment, composite seal spare has very strong sealability than existing monomer seal ring.
Fig. 1 is a cylinder seal sectional view of the present utility model.
Fig. 2 is a frustum formula Sealing sectional view of the present utility model.
Fig. 3 is the utility model composite seal spare structure sectional view.
Fig. 4 is the utility model composite seal spare three-dimensional structure diagram.
Below in conjunction with accompanying drawing the utility model is described specifically:
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, composite seal spare is made up of cylinder seal 1 and frustum formula Sealing 2, cylinder seal 1 is an axle with its medial axis, that middle upper portion has is cylindrical, the bottom then has the taper type through hole, frustum formula Sealing 2 is an axle with its medial axis, the centre has cylindrical hole, frustum formula Sealing 2 is coupled with the taper type through hole of cylinder seal 1, frustum formula Sealing 2 is embedded in the taper type through hole of cylinder seal 1, utilize the elasticity of rubber, the two cooperates in the interference mode.
The frustum of above-mentioned frustum formula Sealing 2 is tall and big in the cylinder height of cylinder seal 1, make the end face of frustum formula Sealing 2 exceed the end face of cylinder seal 1, it is poor to form certain height between the two, when frustum formula Sealing 2 weares and teares with the surface of contact generation of cylinder seal 1, frustum formula Sealing 2 moves inward under the pressure outside effect, realizes automatic wear compensation.
On the cylinder of above-mentioned cylinder seal 1, can crack 3,4 according to oblique the having of needs easy for installation on the cone of frustum formula Sealing 2.
Cracking of above-mentioned cylinder seal 134 can not be in a side with cracking of frustum formula Sealing 2 in installation, prevent from use to cause poorly sealed because of dislocation makes two to crack 3,4 on one side.3,4 both sides that preferably are positioned at the medial axis when mounted of cracking become 180 degree for best.
The oblique face that cracks of above-mentioned cylinder seal 1, frustum formula Sealing 2 is the 40-50 degree with the best angle that the bottom surface became separately.
In as installed, frustum formula shape Sealing 2 is sleeved on the pipe fitting that needs sealing earlier, cylinder seal 1 is enclosed within on the frustum formula shape Sealing 2 and places in the housing of fixing composite seal spare, tighten the housing upper press cover, and composite seal spare applied certain pressure, promptly finish installation to composite seal spare.In actual applications, when the contact surface abrasion of cylinder seal 1 and frustum formula shape Sealing 2, under the gland applied pressure, composite seal spare is realized automatic compensation function.
