Abstract

The utility model relates to a heating pipe, in particular to a clamping board type steam heating pipeline. A clamping board heating pipe comprises a core pipe, an outer protective pipe and an annular supporting plate. The outer protective pipe is provided with moisture removing pipes, the core pipe penetrates through an inner annular hole of the supporting plate, and the core pipe is coaxially arranged in the outer protective pipe through the supporting plate. The clamping board heating pipe is characterized by comprising outer clamping boards and inner clamping boards, one side of each outer clamping board is arranged in an outer clamping groove in the outer outline edge of the supporting plate, the other end of each outer clamping board is fixed to the inner wall of the outer protective pipe, one side of each inner clamping board is arranged in an inner clamping groove in the middle annular hole edge of the supporting plate, the other side of each inner clamping board is attached to the outer wall of the core pipe, and the core pipe can slide on the inner clamping boards. According to the clamping board heating pipe, clamping boards are combined as a whole, the structure is stable, sliding friction is little, and a clamping board structure can be effectively protected.

Description

The clamp thermal pipe

Technical field

The utility model relates to a kind of thermal pipe, is specially the steam heating pipeline of holding plate type.

Background technique

Holding plate type heat distribution pipeline commonly used, inside is distributed between core pipe and outer pillar by a plurality of clamps combination ring-types, and the clamp combination is that mutually vertical two boards is stuck, this simple in structure, easy processing, assembling is quick, but because the clamp combination is separate, in the time of core pipe displacement, easily damage, and core pipe is to slide on clamp, and frictional force is larger, when particularly relatively violent the or displacement of core pipe play is large, easily damage the clamp combination.

The model utility content

For above-mentioned technical problem, the utility model provides a kind of constitutionally stable clamp thermal pipe, and concrete technological scheme is:

The clamp thermal pipe, the dunnage that comprises core pipe, outer pillar and annular, the humidity discharging pipe is arranged on outer pillar, the core pipe is through annular distance in dunnage, being arranged in outer pillar core pipe concentric by dunnage, it is characterized in that: also comprise outer card plate and interior clamp, described outer card plate one side is arranged in the exterior bayonet slot at dunnage external frame edge, the opposite side of outer card plate is fixed on the inwall of outer pillar, described interior clamp one side is arranged in the inner card cage of dunnage central ring bore edges, the opposite side of interior clamp is attached to core tube wall, and the core pipe can slide on interior clamp.

Also comprise dividing plate, dividing plate is annular slab, and the outer wall that is fixedly mounted on the core pipe of dividing plate cuts off the space between core pipe and outer pillar, and respectively there is the humidity discharging pipe both sides of dividing plate.

Described dividing plate is near outer card plate, and the distance between outer card plate is core pipe maximum displacement.

Described interior clamp comprises plate body, ball and spring, and the side that plate body contacts with core tube wall is equipped with ball, and the plate body opposite side is stuck in inner card cage, between plate body and draw-in groove, spring is arranged.

The clamp thermal pipe that the utility model provides, be combined into an integral body by clamp, structural stability, and force of sliding friction is little, effectively protection card plate structure.

Fig. 2 is cross-sectional structure schematic diagram of the present utility model;

Fig. 3 is partial structurtes schematic diagram of the present utility model.

Embodiment

Accompanying drawings embodiment of the present utility model, as depicted in figs. 1 and 2, the clamp thermal pipe, comprise core pipe 1, outer pillar 2 and annular dunnage 5, on outer pillar 2, humidity discharging pipe 3 is arranged, core pipe 1 is through the interior annular distance of dunnage 5, by dunnage 5 by the outer pillar 2 of being arranged on of core pipe 1 concentric, also comprise outer card plate 6 and interior clamp 7, described outer card plate 6 one sides are arranged in the exterior bayonet slot at dunnage 5 external frame edges, the opposite side of outer card plate 6 is fixed on the inwall of outer pillar 2, described interior clamp 7 one sides are arranged in the inner card cage 51 of dunnage 5 central ring bore edges, the opposite side of interior clamp 7 is attached to core pipe 1 outer wall, when 1 temperature distortion of core pipe is stretched, can on interior clamp 7, slide.Outer card plate 6 and interior clamp 5 are perpendicular to dunnage 5.The utility model outer card plate 6 and interior clamp 5 adopt respectively four, evenly annular distribution

Also comprise dividing plate 4, dividing plate 4 is annular slab, and the outer wall that is fixedly mounted on core pipe 1 of dividing plate 4 cuts off the space between core pipe 1 and outer pillar 2, and respectively there is humidity discharging pipe 3 both sides of dividing plate 4, and dividing plate 4 is parallel with dunnage 5.

Described dividing plate 4 is near outer card plate 6, and the distance between outer card plate 6 is core pipe 1 maximum displacement, and dividing plate 4 not only can play the partition effect, prevents from limiting the displacement on shaft axis of core pipe 1.

As shown in Figure 3, described interior clamp 7 comprises plate body 71, ball 72 and spring 73, and plate body 71 is equipped with ball 71 with the side that core pipe 1 outer wall contacts, and plate body 71 opposite sides are stuck in inner card cage 51, between plate body 71 and draw-in groove 51, spring 73 are arranged.Spring 73 can damping, and it is more smooth and easy that ball 72 can allow core pipe 1 move, and reduces frictional force, in case the structure of interior clamp 7 is damaged.
