Abstract
A mouthpiece for 2GS cast tube is a structure used to connect the 2GS cast tubes to be a pipeline as there will be lip shape of rubber ring embedded in inner groove at female mouth of cast tube for sealing and male mouth of another cast tube will be inserted into the female mouth of said cast tube to squeeze and press the lip shape of rubber ring in between the famel mouth and male mouth of the cast tubes closely with contact surface of the said lip shape of rubber ring and liquid inside pipe being a lip shape of concave surface.
Description
(1), technical field
The invention belongs to a kind of interface structure that connects into pipeline with the 2GS cast tube.
(2), background technique
At present, the formula flexible interface of slipping into utilizes the self sealing action of rubber ring to keep seal for pipe joints, because seal ring and liquid in pipe surface of contact plane or convex surface, sealing effect is poor, especially when the pipe internal pressure is high, leakage accident often takes place.
(3), summary of the invention
In order to overcome the shortcoming of prior art, the invention provides a kind of 2GS Cast tube joint, it is simple in structure, and good sealing effect especially is fit to the conveying of highly pressurised liquid.
The present invention solves the technological scheme that its technical problem takes: be embedded with the lip cushion rubber that is used for sealing in the inner groovy of cast tube bellmouth, the socket of another root cast tube is inserted in the bellmouth of described cast tube, the lip cushion rubber tightly is squeezed between the bellmouth and socket of cast tube, described lip cushion rubber and liquid in pipe surface of contact are the lip concave surface.
Because adopt the lip cushion rubber, pipeline pressure is big more like this, the contact pressure of cushion rubber and tube wall is big more, has better guaranteed sealing.
(4), description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Accompanying drawing is a partial sectional view of the present invention.
(5), embodiment
In the inner groovy 5 of cast tube bellmouth 2, be embedded with the lip cushion rubber 3 that is used for sealing, the socket 1 of another root cast tube is inserted in the bellmouth 2 of described cast tube, lip cushion rubber 3 tightly is squeezed between the bellmouth 2 and socket 1 of cast tube, described lip cushion rubber 3 is the lip concave surface with liquid in pipe surface of contact 4.Described lip cushion rubber 3 also can be triangle or semicircle with liquid in pipe surface of contact 4.
Claims (2)
1, a kind of 2GS Cast tube joint, in the inner groovy (5) of cast tube bellmouth (2), be embedded with the lip cushion rubber (3) that is used for sealing, the socket of another root cast tube (1) is inserted in the bellmouth (2) of described cast tube, lip cushion rubber (3) tightly is squeezed between the bellmouth (2) and socket (1) of cast tube, it is characterized in that: described lip cushion rubber (3) is the lip concave surface with liquid in pipe surface of contact (4).
2,2GS Cast tube joint according to claim 1 is characterized in that: described lip cushion rubber (3) also can be triangle or semicircle with liquid in pipe surface of contact (4).
