Abstract
The utility model relates to a steel-plastic compounded 90-degree elbow reinforcing pipe fitting with higher pressure resistance, which mainly solves the problem that the present steel-plastic compounded 90-degree elbow reinforcing pipe fitting has weak pressure resistance at the 90-degree corner. The steel-plastic compounded 90-degree elbow reinforcing pipe fitting is characterized in that a reinforced rib (4) is fixed at the 90-degree corner part of a reinforcing framework (2) and is provided with a through hole (3). On the basis of the present the pipe fitting, the structure and the material of the built-in metal steel framework are improved and the strength and the structural stability of the steel-plastic compounded 90-degree elbow reinforcing pipe fitting can be improved, so that the service life of the steel-plastic compounded 90-degree elbow reinforcing 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 0 ° of elbow reinforcement of compound 69 pipe fitting.
Background technique
It is a kind of joint during pipeline connects that 90 ° 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 0 ° of bend pipe tools of compound 69, 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 0 ° of bend pipe tools of compound 69 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 0 ° of bend pipe tools of compound 69, influence the proper functioning of institute's unicom pipeline.
The model utility content
Mould the problem of 0 ° of bend pipe tools corner resistance to compression of compound 69 weakness in order to solve existing steel, the utility model provides a kind of steel to mould 0 ° of elbow reinforcement of compound 69 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 0 ° of elbow of compound 69 is strengthened pipe fitting, moulds the working life that 0 ° of elbow of compound 69 is strengthened pipe fitting thereby prolong steel.
The technical solution of the utility model is: a kind of steel is moulded 0 ° of elbow of compound 69 and is strengthened pipe fitting, comprises that plastic substrate and built-in metal strengthen skeleton, wherein, at the fixing stiffening rib of 90 ° of rotation angle positions that strengthen 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 tube wall thickness.
The beneficial effects of the utility model are: owing to strengthen the fixing stiffening rib that can improve the skeleton bulk strength of 90 ° of rotation angle positions of skeleton at metal, the voltage endurance capability that makes steel mould 0 ° of bend pipe tools of compound 69 improves by a relatively large margin, moulds the working life that 0 ° of elbow of compound 69 is strengthened pipe fitting thereby prolong steel.

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
Below in conjunction with accompanying drawing the version model utility is described further
By Figure 1 and Figure 2, this steel is moulded 0 ° of elbow reinforcement of compound 69 pipe fitting and is comprised that 90 ° of elbow plastic substrates 1 and 90 ° 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 of 90 ° of rotation angle positions of 0 ° of bend pipe tools of compound 69 in order to improve steel, avoid stress to concentrate, make steel mould the stable of 0 ° of bend pipe tools pressure rating raising of compound 69 and structural behaviour, mould the fixing stiffening rib 4 that can improve the skeleton bulk strength of 90 ° of rotation angle positions of 0 ° of elbow skeleton 2 of compound 69 at steel, stiffening rib 4 is welded to and 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.Strengthening skeleton 2 is high-strength steel sheet, highly increases to 3～4 times of tube wall thickness, improves 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, make its plastic substrate 1 and the enhancing skeleton 2 direct injection-compression moldings of being with stiffening rib 4, on the basis that does not increase processing cost, the whole voltage endurance capability that makes steel mould 0 ° of bend pipe tools of compound 69 is greatly improved, thereby prolongs the working life of 90 ° of bend pipe tools.
Claims (3)
1. a steel is moulded 0 ° of elbow reinforcement of compound 69 pipe fitting, comprises that plastic substrate (1) and built-in metal strengthen skeleton (2), and it is characterized in that: 90 ° of rotation 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 0 ° of elbow of compound 69 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 0 ° of elbow of compound 69 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.
