Abstract

The utility model discloses an inspection hole member for a vertical pipe. The inspection hole member comprises an inspection hole component and a cap component, wherein the inspection hole component comprises a pipeline part and an inspection hole part; a round hole is formed at the joint of the pipeline part and the inspection hole part; the inspection hole part is cylindrical; an external thread is formed on the inspection hole part; positioning blocks are arranged in the joint of the inspection hole part and the pipeline part; the cap component comprises an inner cap and an outer cap; the inner cap is provided with a cylinder which can be inserted into the inspection hole part; the cylinder is provided with notches into which the positioning blocks can be inserted in a matched mode; the inner end surface of the cylinder is an arc surface fitted with the curved surface of the inner wall of the pipeline part; the outer cap is provided with an internal thread screwed with the external thread on the inspection hole part in a matched mode and a concave part for pressing the inner cap; a certain distance is formed between the inner and outer ring surface of the concave part and the internal thread, so that a ring cavity for accommodating the wall of the inspection hole part is formed; and a sealing ring is arranged at the bottom of the ring cavity. The inspection hole member has the advantages of simple structure and low cost.

Description

A kind of standpipe inspection socket member

Technical field

The utility model relates to a kind of pipe fitting, particularly a kind of standpipe inspection socket member.

Background technique

In vertical duct construction, on general every layer or the interlayer standpipe inspection socket is set all, to make things convenient for the maintenance of pipeline.Existing inspection socket and inspection cover are shown in Figure 1A and Figure 1B; Standpipe inspection socket 11 is provided with outside thread 13, and inspection cover 12 is provided with and is mated the internal thread 14 that is spirally connected, and adopts the pipeline of this kind product and Placement; What adopt is the method for thread seal; In case when standpipe inspection socket 11 or inspection cover 12 received the ectocine distortion, the installation between standpipe inspection socket 11 and the inspection cover 12 is difficulty very, and sealing also can not get guaranteeing.In addition, the bottom surface 15 of inspection cover 12 is a plane, with curved surface 16 transition smoothly of standpipe inwall, when current pass through standpipe inspection socket 11, forms impact at both engagement positios, might produce cavitation, causes pipe vibration and produces noise.

Chinese patent notice of authorization CN2583482 discloses a kind of pipe fitting inspection socket and inspection cover, though solved the problem of cavitation, its complex, manufacture cost are too high.

The model utility content

The technical problem that the utility model will solve is to provide a kind of to the existing in prior technology problem can solve cavitation and a kind of standpipe inspection socket member simple in structure, that cost is low.

For achieving the above object, the technological scheme of the utility model is following:

A kind of standpipe inspection socket member; Comprise inspection socket parts and flap parts; Wherein said inspection socket parts comprise pipe section and inspection socket part, and the inspection socket part forms a circular hole with the joint of pipe section, and said inspection socket partly is cylindric; Oral area in said inspection socket part is provided with outside thread, and said inspection socket part is provided with at least one positioning block with inside, pipe section joint; Said flap parts comprise inner cap and enclosing cover; Said inner cap has one can insert the interior cylinder of said inspection socket part; Have at least one on the said cylinder and can cooperate the short slot that inserts with said positioning block, the interior edge face of this cylinder is the arc surface that coincide with said pipe section inwall curved surface; Said outer cover be provided with the inspection socket part on outside thread cooperate the internal thread that is spirally connected and in order to compress the female parts of inner cap; The certain distance in interval between the inside and outside anchor ring of said female parts and the said internal thread; The ring cavity of inspection socket part wall is held in formation one, is placed with a seal ring in the bottom of said ring cavity.

Partly with on the inside, pipe section joint be symmetrically arranged with two positioning blocks at said inspection socket, said cylinder is provided with two can cooperate the short slots that insert with corresponding positioning block.

Owing to adopted technological scheme as above; The inspection socket parts of the utility model cooperate assembling with the flap parts after; Utilize the outer indent that covers that inner cap is held out against, arc surface that covers in making and pipe section inwall curved surface fit like a glove, and have reduced the impact of flow to pipeline; Realized the noise reduction of pipeline in the flow of fluid process, Analysis of Pipe Vibrations greatly reduces simultaneously.The utlity model has simple in structure, the advantage that cost is low.

Description of drawings

Embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.

Referring to Fig. 2 and shown in Figure 3; A kind of standpipe inspection socket of the utility model member comprises inspection socket parts and flap parts; Wherein the inspection socket parts comprise pipe section 110 and inspection socket part 120, and inspection socket part 120 forms a circular hole 130 with the joint of pipe section 110.The upper/lower terminal of pipe section 110 has the interface 111,112 that is connected with standpipe.

Inspection socket part 120 is cylindric, is provided with outside thread 121 at the oral area of inspection socket part 120, on inspection socket part 120 and inside, pipe section 110 joint, is symmetrically arranged with two positioning blocks 140,140a.

The flap parts comprise inner cap 210 and enclosing cover 220, and inner cap 210 has the cylinder 211 that can insert in the inspection socket part 110, and cylinder 211 is provided with two can cooperate short slot 212, the 212a that inserts with corresponding positioning block 140,140a.The interior edge face 213 of this cylinder 211 is the arc surface that coincide with pipe section 110 inwall curved surfaces.

Enclosing cover 220 be provided with inspection socket part 120 on outside thread 121 cooperate internal thread 221 and the female parts 222 that is spirally connected in order to compress inner cap 210; The certain distance in interval between the inside and outside anchor ring 222a of female parts 222 and the internal thread 221; The ring cavity 223 of inspection socket part 120 walls is held in formation one, is placed with a seal ring 224 in the bottom of ring cavity 223.
