Abstract

The utility model discloses an antiseptic water delivery pipe for a deep well pumping, a chemical industry liquid conveying and city construction supplying and discharging of the raceway. The antiseptic water delivery pipe is composed of a pipe wall and a flange arranged at the end of the pipe wall, which is characterized in that the pipe wall integrates the flange into not unit, and made of the plastic or the resin material which are casted together. The inner wall of the pipe is provided with a metal hollow cylinder frame along the axial direction, the wall of the circumference is provided with a casting hole; both ends of the metal hollow cylinder frame is welded with the inner end of the metal ring frame in the flange; the ring frame is provided with a casting hole, and the flange is provided with a bolt hole. The utility model has the advantages of reasonable structure, convenient selection, good corrosion resistance, high intensity of the quality lightness, smooth inner wall, long service life. The utility model is an ideal antiseptic water delivery pipe.

Description

Anticorrosion conduit pipe

Technical field the utility model relates to a kind of anticorrosion conduit pipe, is applicable to that deep-well pumping, chemical liquid are carried and the conduit pipe of urban construction plumbing.

Background technique is present, and the water pipe that is used for deep-well pumping mainly is an iron pipe, easily oxide etch, and the life-span has only 2-3, and easy-rupturing falls pump, causes bad well of pump to ruin, and economic loss is bigger; Common plastics tube is generally adopted in the conveying of chemical liquid, but its intensity is low, and the pressure that bears is little, as then price is higher with stainless steel or copper pipe; There is perishable pollution in the used iron pipe of urban construction plumbing, the cost height, and the heavy rapid wear of matter, transportation inconvenience and the big problem of water flowing resistance are arranged with reinforced concrete pipe.

Summary of the invention goal of the invention of the present utility model is to have proposed a kind of anticorrosion conduit pipe at above-mentioned existing problem, the metal frame that has hollow cylinder and annulus to form in this conduit pipe is surrounded by the tube wall of plastics or resin material formation and the flange plate at tube wall two ends outward.

The purpose of this utility model realizes by following technical measures:

The utility model is made up of the flange plate at tube wall and tube wall two ends, its characteristics, tube wall and flange plate are one, make by plastics or resin material casting, enclosing its center of circle in tube wall has vertically hollow metal cylinder body skeleton, leaves pouring orifice on this hollow cylinder skeleton peripheral wall, and weld mutually with metal cirque skeleton interior edge face in the flange plate at two ends, leave pouring orifice on the metal cirque skeleton equally, enclose its center of circle on the flange plate and be evenly equipped with the axial bolts hole.

The utility model advantage is rational in infrastructure, selection convenience, good corrosion resistance, light weight intensity height, inner wall smooth, long service life, cost are low, is a kind of desirable anticorrosion conduit pipe.

Description of drawings is described in detail embodiment of the present utility model below in conjunction with accompanying drawing:

Fig. 1 is a main sectional view of the present utility model.

Fig. 2 is an end view drawing of the present utility model.

Fig. 3 is the A-A sectional view of the utility model Fig. 1.

Fig. 4 is the B-B sectional view of the utility model Fig. 1.

Embodiment is known by Fig. 1-4, present embodiment is by tube wall (1), the flange plate at tube wall two ends (4) is formed, its characteristics, tube wall (1) is an one with flange plate (4), make by plastics or resin material casting, in tube wall (1), enclose its center of circle vertically hollow metal cylinder body skeleton (2) is arranged, leave pouring orifice (3) on the peripheral wall of this hollow cylinder skeleton (2), so that combine casting with tube wall (1), hollow cylinder skeleton (2) two ends are welded on interior metal cirque skeleton (6) interior edge face of flange plate (4), leave pouring orifice (3) on the round metal cup skeleton (6) equally, be convenient to combine casting with flange plate (4), enclose its center of circle on the flange plate (4) and be evenly equipped with 4 axial bolts holes (5), be used for the connection between the tube and tube.

Claims

1, a kind of anticorrosion conduit pipe, flange plate (4) by tube wall (1) and tube wall two ends is formed, it is characterized in that tube wall (1) and flange plate (4) one are by plastics or resin material casting making, hollow metal cylinder body skeleton (2) is arranged in the tube wall (1), and metal cirque skeleton (6) interior edge face in the two ends of this hollow cylinder skeleton (2) and the flange plate (4) welds mutually.
