Abstract
The invention belongs to joint apparatus technical field, more particularly to a kind of special-shaped ring seal.The invention discloses special-shaped ring seal, special-shaped ring seal includes ring bodies and through hole, described through hole is up-narrow and down-wide, the edge of the upper surface of ring bodies offers deep trouth body, the cross section of described deep trouth body is inverted triangle, the place in the inner part of the upper surface of ring bodies is provided with shallow slot body, is communicated between described deep trouth body and shallow slot body.The beneficial effects of the invention are as follows：Completion can be just pressed without very big strength in pressing, and cavity pressure is higher, and sealing effectiveness is more preferable.
Description
Technical field
The invention belongs to joint apparatus technical field, more particularly to a kind of special-shaped ring seal.
Background technology
Joint is to be applied to the water delivery occasions such as agricultural irrigation, Urban Waterlogging.Joint is by oedoeagus part, female end part, O-ring
The wrench assembly of seal, connection oedoeagus and female end is constituted, and spanner is arranged on oedoeagus, and O-ring seal is arranged on female end endoporus.
O-ring seal is solid rubber parts, O-ring is occurred shape on spanner in use, very big power must be acted in pressing
Become, can be only achieved sealed effect, must borrow boosting-rod for the joint of big specification when in use, just and can be only achieved to press
This requirement.
The content of the invention
It is an object of the invention to solve the problems, such as techniques discussed above there is provided it is a kind of pressing when without very big strength
Completion can be just pressed, and cavity pressure is higher, and the more preferable special-shaped ring seal of sealing effectiveness, its technical scheme is as follows：
Special-shaped ring seal, it is characterised in that special-shaped ring seal includes ring bodies and through hole, it is narrow on described through hole under
Width, the edge of the upper surface of ring bodies offers deep trouth body, and the cross section of described deep trouth body is inverted triangle, ring-type
The place in the inner part of the upper surface of body is provided with shallow slot body, is communicated between described deep trouth body and shallow slot body.
Preferred embodiment is to be provided with angular protrusions at the upper lateral part of ring bodies.
Preferred embodiment is that the middle sidepiece of ring bodies and following side are arc transiting surface, the middle sidepiece of ring bodies and following side
Radian it is inconsistent.
The special-shaped ring seal that the present invention is provided, when in use, whole abnormity ring seal are provided in the moon
At the bottom for holding part.Through hole is to be used to connect oedoeagus part and female end part, and the top for the oedoeagus part for being is deep by through hole
Enter to female end partial interior.The main function of deep trouth body and shallow slot body is so that female end part cavity pressure is higher, sealing effectiveness
More preferably, and add shallow slot body cause pressurization when so that be pressurized have more equalization performance so that sealing property is more preferable.
The angular protrusions of the present invention be able to can preferably coordinate with female end part so that special-shaped ring seal is more preferable
It is sealed in special-shaped ring seal, also there is better seal while slip difficult for drop-off.
The middle sidepiece of the ring bodies of the present invention and the radian of following side are inconsistent.Both radians are inconsistent so that special-shaped
Ring seal is arranged on female end timesharing, and the lower section of special-shaped ring seal and female end part have gap, so that close
Feng Shi, special-shaped ring seal is pressurized and can be close on female end part and oedoeagus part so that sealing property is more preferable.
The beneficial effects of the invention are as follows：In pressing completion, and cavity pressure can be just pressed without very big strength
Higher, sealing effectiveness is more preferable.
Brief description of the drawings
Fig. 1 is schematic diagram of the invention.
Embodiment
With reference to Fig. 1 specific illustrative embodiments：
Special-shaped ring seal, special-shaped ring seal includes ring bodies 1 and through hole 2, and described through hole 2 is up-narrow and down-wide, ring-type
The edge of the upper surface of body 1 offers deep trouth body 3, and the cross section of described deep trouth body 3 is inverted triangle, ring bodies 1
The place in the inner part of upper surface be provided with shallow slot body 4, communicated between described deep trouth body 3 and shallow slot body 4.
Preferred embodiment is that angular protrusions 5 are provided with the upper lateral part of ring bodies 1.
Preferred embodiment is that the middle sidepiece of ring bodies 1 and following side are arc transiting surface 6, the middle sidepiece of ring bodies and downside
The radian in portion is inconsistent.
When in use, special-shaped ring seal is arranged in the endoporus of female end part, the bottom positioned at female end part
Place.
