Abstract

The utility model relates to a pipeline fitting directly connected with a moveable connecting piece, which can be any one of an elbow pipe, a three-way pipe, and a connecting pipe. The moveable connecting piece is composed of an upper connecting head and a connecting head screw nut; at least one connecting head of the pipeline fitting is provided with an external thread to be matched with the connecting head screw nut; the upper end of an internal hole of the connecting head is provided with a taper hole which corresponds to a tapered sealing surface on the lower part of the upper connecting head. When the taper hole and the tapered sealing surface of the upper connecting head are contacted with each other in a sealing mode, a proper gap is arranged between the top surface of the connecting head, provided with the external thread, of the pipeline fitting and the lower bottom surface of a circular bead of the upper connecting head. The utility model has the advantages of convenient installation, work efficiency enhancement, favorable centering property, and material saving.

Description

Directly be connected with the pipeline fittings of loose joint part

The utility model relates to the link of pipeline, and concrete is a kind of pipeline fittings that directly is connected with the loose joint part.

The worker, agricultural and life civil area, particularly at chemical industry, many water flowings are arranged in the building, gas, oil, the pipeline of chemical mediator (pipeline), these pipelines dispose various valves according to designing requirement, and widely-used elbow, threeway, joint, standardized pipeline fittingses such as loose joint part carry out the scene and install, in many mounting processs, the position of loose joint part is to be placed on elbow, threeway, be advisable in the joint vicinity, must be connected in series installation with loose joint and other annex to pipeline processing like this, the numerous and diverse inconvenience of technology, up to now, pipeline fittings and loose joint parts all on the market all are monomer structures, do not have a kind of pipeline fittings directly to be connected with the loose joint part.

The purpose of this utility model provides a kind of pipeline fittings that directly is connected with the loose joint part, reaches purpose easy for installation, good to neutrality, economical with materials.

The purpose of this utility model is achieved in that

A kind of pipeline fittings that directly is connected with the loose joint part, this pipeline fittings can be elbow, threeway, in the adapter any, described loose joint part is made up of upper connection and Female connector fittings, this upper connection top outer cylinder is stretched out from the Female connector fittings endoporus, the middle part cylindrical has the ring-type that compresses for nut to protrude shoulder, shoulder bottom cylindrical is a conical seal (contact) face, the center of this upper connection is a through hole, this through hole upper end is an internal thread, it is characterized in that: at least one joint of described pipeline fittings is shaped on outside thread and Female connector fittings matches, the conical seal (contact) face that this joint endoporus upper end is taper hole and upper connection bottom is corresponding, when this taper hole and upper connection conical seal (contact) face become sealing to contact, leave suitable gap between the shoulder bottom surface that is shaped on externally threaded joint end face and upper connection of described pipeline fittings.

Describedly comprise the piping attachment of elbow, threeway, adapter and comprise that the loose joint part of upper connection, Female connector fittings can make with metallic material, also can make with nonmetallic material.

The utility model has following actively useful effect:

1, former loose joint part comprises upper and lower joint and locknut, need to be connected with pipeline fittings by a short tube (or internal thread), the loose joint part of this product has saved lower contact and nipple, directly is connected with pipeline fittings with upper connection, locknut, thereby simplified mounting process, improved work efficiency.

2, good to neutrality, certain flexibility ratio is arranged.

3, save raw material, each loose joint can be saved 25% steel approximately, if promote in the whole nation, the annual steel of saving will be large numbers.

4, loose joint part structure of the present utility model is applicable to elbow, threeway, reducing tee, adapter and other piping attachments, make standardized structural elbow loose joint, threeway loose joint, take over product such as loose joint market be provided, increase the new varieties of piping attachment, used the range of choice of pipeline fittings when having enlarged construction.

5, structure of the present utility model is applicable to metal and nonmetallic piping attachment.

Now in conjunction with the accompanying drawings:

Fig. 1 is the embodiment that the utility model is applied to elbow;

Fig. 2 is the embodiment that the utility model is applied to threeway;

Fig. 3 is the embodiment that the utility model is applied to take over.

Accompanying drawing number:

1. 101. cylindrical annular shoulders of the upper connection in the loose joint part

102. conical seal (contact) face 103. endoporus

104. internal thread

2. the locking nut in the loose joint part

3. elbow 301. outer round threads

302. 303. fitting surface gaps, female cone hole

4. threeway 5. is taken over

The pipeline fittings that directly is connected with the loose joint part of the present utility model, this pipeline fittings can be elbow, threeway, in the adapter any, described loose joint part is made up of upper connection 1 and Female connector fittings 2, this upper connection top outer cylinder is stretched out from the Female connector fittings endoporus, the middle part cylindrical has the ring-type that compresses for nut to protrude shoulder 101, shoulder bottom cylindrical is a conical seal (contact) face 102, the center of this upper connection is a through hole 103, this through hole upper end is an internal thread 104, at least one joint of described pipeline fittings (also can be two joints, three joints) being shaped on outside thread 301 matches with Female connector fittings 2, this joint endoporus upper end is that taper hole 302 is corresponding with the conical seal (contact) face 102 of upper connection bottom, when 102 one-tenth sealings of this taper hole 302 and upper connection conical seal (contact) face contact, leave suitable gap 303 between the bottom surface of the joint end face that is shaped on outside thread 301 of described pipeline fittings and the shoulder 101 of upper connection.

During enforcement, describedly comprise elbow 3, threeway 4, take over 5 piping attachment and comprise upper connection 1 that Female connector fittings 2 can be made with metallic material at interior loose joint part, also can make with nonmetallic material.

Fig. 1 shows the embodiment who is applied to elbow 3, and loose joint part 1,2 is installed on an end of elbow 3;

Fig. 2 shows the embodiment who is applied to threeway, and loose joint part 1,2 is installed on the transition joint of threeway 4, can be installed on arbitrary joint of threeway (comprising reducing tee) during enforcement, also can be installed on two, three joints in the threeway simultaneously.

Fig. 3 shows that the embodiment, the loose joint part 1,2 that are applied to adapter (two is logical) are installed on a joint of adapter 5.
