Abstract
The utility model relates to a steel-plastic composite 45-degree elbow strengthening pipe fitting with pressure resisting capacity, mainly solving the problem that the corner of a traditional steel-plastic composite 45-degree elbow strengthening pipe fitting has weak pressure resisting capacity. The steel-plastic composite 45-degree elbow strengthening pipe fitting is characterized in that a reinforcing rib (4) capable of improving the integral strength of a framework is fixed at a 45-degree angle part of a reinforcing framework (2), and the reinforcing rib (4) is provided with through holes (3). For the pipe fitting, the structure and material of a built-in metal steel framework is improved on the basis of a traditional pipe fitting, and the strength and structural stability of the steel-plastic composite 45-degree elbow strengthening pipe fitting are improved, thereby the service life of the steel-plastic composite 45-degree elbow strengthening pipe fitting is prolonged.
Description
Technical field
The utility model relates to the composite steel-plastic pipe fitting joint, and a kind of steel that especially has higher voltage endurance capability is moulded compound 45 ° of elbows reinforcement pipe fitting.
Background technique
It is a kind of joint during pipeline connects that 45 ° of elbows are strengthened pipe fitting, the pipeline of different direction can be interconnected.It is to be matrix with high density polyethylene (HDPE) (HDPE) that steel is moulded compound 45 ° of bend pipe tools, and the built-in Steel Skeleton of matrix utilizes the pipe fitting mold injection-compression molding as reinforcing phase.Its voltage withstand class mainly guarantees by the intensity of Steel Skeleton.The skeleton material that existing steel is moulded compound 45 ° of bend pipe tools is Q235, in the process of boosting, the corner of pipe fitting is the resistance to compression weakness zone, phenomenons such as skeleton is torn, explosion often occur, cause steel to mould the life cycle weak point of compound 45 ° of bend pipe tools, influence the proper functioning of institute's unicom pipeline.
The model utility content
Mould the problem of compound 45 ° of bend pipe tools corner resistance to compression weaknesses in order to solve existing steel, the utility model provides a kind of steel to mould compound 45 ° of elbows reinforcement pipe fitting.This pipe fitting is on the basis of existing pipe fitting, and the structure and the material of built-in metallic steel skeleton are improved, and has improved steel and has moulded intensity and the structural stability type that compound 45 ° of elbows are strengthened pipe fitting, moulds the working life that compound 45 ° of elbows are strengthened pipe fitting thereby prolong steel.
The technical solution of the utility model is: a kind of steel is moulded compound 45 ° of elbows and is strengthened pipe fitting, comprises that plastic substrate and built-in metal strengthen skeleton, and wherein, the fixing stiffening rib at the 45 position that strengthens skeleton has penetration hole on the stiffening rib.
Strengthening skeleton is the Q345 steel plate; The height of stiffening rib is 3～4 times of product tube wall thickness.
The beneficial effects of the utility model are: because at the fixing stiffening rib that can improve the skeleton bulk strength in the bent angle position of metal enhancing skeleton, the voltage endurance capability that makes steel mould compound 45 ° of bend pipe tools improves by a relatively large margin, thereby prolongs the working life of 45 ° of pipe fittings.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of sequence number 2 skeletons among Fig. 1.
1-plastic substrate among the figure, 2-strengthens skeleton, 4-stiffening rib, 3-penetration hole.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing
By Figure 1 and Figure 2, this steel is moulded compound 45 ° of elbows reinforcement pipe fitting and is comprised that 45 ° of elbow plastic substrates 1 and 45 ° of elbow metals strengthen skeletons 2, and enhancing skeleton 2 places in the plastic substrate 1 by the mode of mould injection-compression molding.Mould the intensity at compound 45 ° of bend pipe tools 45 positions in order to improve steel, avoid stress to concentrate, make steel mould the stable of compound 45 ° of bend pipe tools pressure ratings raising and structural behaviour, the fixing stiffening rib 4 that can improve the skeleton bulk strength at the 45 position that strengthens skeleton 2, stiffening rib 4 is welded to the corner that strengthens skeleton 2, and have penetration hole 3 on the stiffening rib 4, be used to connect the plastic coatings of stiffening rib 4 both sides, prevent that it from coming off.Strengthen skeleton 2 and adopt high-strength steel sheet, highly increase to 3～4 times of pipe fitting thickness, to improve the bulk strength that strengthens skeleton 2.
The processing of this pipe fitting is that corresponding site is opened the stiffening rib skewed slot on former compression moulding die, with the enhancing skeleton 2 direct injection-compression moldings of its plastic substrate 1 with band stiffening rib 4, on the basis that does not increase processing cost, the whole voltage endurance capability that makes steel mould compound 45 ° of bend pipe tools is greatly improved, thereby prolongs the working life of 45 ° of pipe fittings.
Claims (3)
1. a steel is moulded compound 45 ° of elbows reinforcement pipe fitting, comprises that plastic substrate (1) and built-in metal strengthen skeleton (2), and it is characterized in that: 45 ° of bent angle positions of enhancing skeleton (2) are stiffening rib (4) fixedly, has penetration hole (3) on the stiffening rib (4).
2. a kind of steel according to claim 1 is moulded compound 45 ° of elbows and is strengthened pipe fitting, it is characterized in that: strengthen skeleton (2) and be the Q345 steel plate.
3. a kind of steel according to claim 1 is moulded compound 45 ° of elbows and is strengthened pipe fitting, and it is characterized in that: the height of stiffening rib (4) is 3～4 times of tube wall thickness.
