Abstract
The utility model relates to an anti-slippage sealing ring. A round sealing layer with a V-shaped mouth on a cross section is arranged at the lower part of the sealing ring, and a fixed layer with an L-shaped cross section is arranged at the upper part of the sealing ring; a plurality of anti-slippage tooth-shaped quads are uniformly distributed in the circumference direction of the L-shaped fixed layer, and jagged teeth are respectively arranged on the inner sides of the tooth-shaped quads. The utility model is rapid, high-efficiency and economic to mount; when a pipeline is stressed by external force, self weight or internal fluid to slip at a joint, the teeth of the tooth-shaped quads can engage with the outer surface of a pipe faucet so as to save the trouble that the pipeline in bending, climbing or passing an unstable stratum is prevented from slipping by adopting a method for casting a cement thrust block seat.
Description
Technical field
The utility model belongs to carries T type ductile iron pipe, the anti-slip technical field of pipe fitting sealing joint that is used to hydraulic fluid.
Background technique
Under common geological condition, the Sealing of standard T type cushion rubber as jointing generally adopted in the installation of T type ductile iron pipe; But on soft basis, regional, the abrupt slope of depression or pipeline corner; The normal relative displacement that pipe way takes place has the risk that causes interface slippage between pipe and/or the pipe fitting.At present in pipelining when the above-mentioned geological environment, for reaching the slippage that prevents therebetween, often adopt the mode of concreting thrust block, time-consuming more though this method can reach the purpose that prevents that pipe way is subjected to displacement, and cost is very high.
Summary of the invention
The purpose of this utility model is exactly in order to overcome the above problems, and a kind of slippage that can effectively prevent between pipe way in the pipeline and/or pipe fitting is provided, and anti-slip seal ring convenient, high-efficiency and economic is installed.
The technical solution of the utility model is achieved like this: a kind of anti-slip seal ring is characterized in: its bottom, cross section is the circular seal layer that has the V-type lip, and top, cross section is to be L shaped fixed bed; Uniform several anti-skidding profile of tooth abaculus on the circumferencial direction in L type fixed bed, the inboard of anti-skidding profile of tooth abaculus has serrated teeth.
The utility model is a kind of sealing joint circle with excellent sealing and deflection characteristic, the sealing position makes the deformation of V-arrangement lip when tube interior has pressure fluid, be close to pipe socket outer wall to prevent the interface slippage between pipe and/or the pipe fitting with the profile of tooth abaculus, under the corner and unsettled geological condition of pipeline, and the upper and lower slope of pipeline the time can effectively prevent the relative displacement between pipe and/or pipe fitting, avoided the slippage accident.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model user mode schematic representation.
Among the figure: 1, profile of tooth abaculus 2, fixed bed 3, sealing layer 4, V-arrangement lip 5, ductile iron pipe socket 6, spheroidal graphite cast iron tube faucet
Embodiment:
As seen from Figure 1, the utility model is made of profile of tooth abaculus 1, fixed bed 2, sealing layer 3, V-arrangement lip 4.Bottom, the utility model cross section is to have V-type or U type lip 4 circular seal layers 3, and top, cross section is to be L shaped fixed bed 2; Uniform several anti-skidding profile of tooth abaculus 1 on the circumferencial direction in L type fixed bed, the inboard of anti-skidding profile of tooth abaculus 1 has a plurality of serrated teeth, and serrated teeth quantity can be one to four.The relative pipe socket of the tooth of profile of tooth abaculus is reversed acanthoid, thereby can effectively prevent slippage.
As seen from Figure 2, in the use anti-slip seal ring is put into the groove of cast tube bellmouth 6, cast tube socket 5 is pushed cast tube bellmouth 6, pipe just connects together by anti-slip T RunddichtringO like this.Be subjected to external force, self gravitation or internal fluid pressure effect as pipeline, at jointing during to outside slippage, because of frictional force or internal pressure effect make 4 deformation of V-arrangement lip, drive profile of tooth abaculus 1 and be close to pipe 5 socket outer wall, once the socket 5 between pipeline is when breaking away from displacement mutually with respect to bellmouth 6, the tooth blade of profile of tooth abaculus 1 promptly hooks the outer surface of pipe socket 5, plays anti-slip effect.Saved pipeline when turning round, climbing or passing through unsettled stratum, necessary concreting thrust block effectively prevents the slippage of pipe.
