Abstract
The utility model discloses a water pipe elbow with a flow guide threaded groove, which relates to the field of manufacture of water supply equipment. The internal wall of a water pipe elbow wall (2) is provided with a flow guide threaded groove (1); when water flow passes the water pipe elbow, the flow guide threaded groove (1) guides the water flow into a spiral water flow, thereby reducing eddy flow, lowering the pressure of water flow on the water pipe elbow wall (2) and prolonging the service life of the water pipe elbow. The water pipe elbow with a flow guide threaded groove has simple structure, and is easy to manufacture.
Description
Technical field
The utility model relates to water facilities and makes the field, is a kind of water pipe elbow with the water conservancy diversion thread groove concretely.
Background technique
Water pipe at the turning by there being the several angle water pipe elbow to connect two straight water pipes; current are through the turning of elbow during use; usually can produce turbulent flow, water pipe elbow bears bigger pressure, uses the joint of water pipe elbow and water pipe to come off aging easily for a long time and causes leaking.
Summary of the invention
For the turning that overcomes existing elbow produces turbulent flow, the defective that the pressure that water pipe elbow bears is bigger, the utility model provides a kind of water pipe elbow with the water conservancy diversion thread groove, and when the turning of current through elbow, water pipe elbow bears less pressure.
The technical solution used in the present invention is: the inwall at water pipe elbow is provided with the water conservancy diversion thread groove, the pitch of water conservancy diversion thread groove is 3-8mm, the groove depth of water conservancy diversion thread groove is 0.4-0.6mm, the helix angle of water conservancy diversion thread groove is 14-16 °, and helix angle is the tangent line of water conservancy diversion thread groove and the angle of the tube wall tangent line that passes through the point of contact.
The beneficial effects of the utility model are: during current process water pipe elbow, the guiding of water conservancy diversion thread groove current is spiral water flow, thereby reduces turbulent flow, has reduced the pressure of current to pipe inner wall, has prolonged the working life of water pipe elbow.The utility model is simple in structure, is easy to make.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the sectional drawing of right angle water pipe elbow.
Among the figure, 1, the water conservancy diversion thread groove; 2, the water pipe elbow tube wall.
Embodiment
