Abstract

The utility model discloses a joint of salt delivering pipelines, which is used for salt delivering pipelines in salt fields. The utility model is composed of a pipeline head (1), a female lock (2) and a pipeline head (3), wherein, the pipeline heads (1) and (3) are respectively sheathed with the salt delivering pipeline; the female lock (2) is sheathed at contact position of the two pipeline heads along a radial direction, and the two pipeline heads are fastened by the female lock (2). The utility model is formed in the way that nylon materials are pressed. The utility model has the advantages that the leak rate is low, the service life is long, steels can be saved, etc. The utility model is suitable for the various salt fields.

Description

Joint of salt delivering pipeline

The utility model relates to the salt transporting tube road joint, particularly nylon pipeline joint that a kind of salt pan salt transporting tube is used, and belongs to the salt transporting tube road accessory of Salt production.

At present, each saltern, national sea salt district, great majority adopt miniature movable type salt transporting tubes road group equipment to receive salt in the receipts salt technology, and unit is made of equipment such as brine pump, brine pump, salt transporting tube road and sieve bends.The salt transporting tube road adopts the PVC hard plastic tube always, and this plastic tube joint length is generally all about 8 meters.But the duct length that each saltern need be used is all more than 150 meters.Need like this to form by many pipes.Every work 2-3 hour, will take pipeline apart and move (generally will shift out beyond 80 meters) to other position and re-assembly work.Therefore the joint that connects every plastic tube requires promptly can not leak, and dismounting is convenient rapidly again.The quality that pipeline connects directly affects ordinary production.What used pipe coupling was adopted all is the quick clamp joint of steel.It is made up of six parts such as 2 of one-sided inclined-plane flange tube heads, 1 on a pair of, the little axle of " V " type groove clamp, 1 of garden taper pins, need according to circumstances add the rubber cushion of different-thickness during assembling.Practical practice shows that there are many deficiencys in this tube head:

1, assembling difficulty, the operating time is long;

2, directly contact for a long time with bittern, seriously corroded, iron oxide comes off, and can't guarantee original physical dimension;

3, because " V " type clamp is to cast to form, flange corrosion in addition, every set of joints cushioning is diversified in specifications, needs the rubber pad of deposit plurality of specifications;

4, use 1 year end face of flange later, because of corrosion oxidation iron comes off unevenly, water leakage phenomenon is serious;

5, on the structural design, the fastening limit is arranged self.Promptly after garden taper pin and hole fit like a glove, again can't be fastening.If the flange screw degree is not enough, have to take apart and add pad again, re-assembly;

6, clamp is made difficulty, labor strength is big, and material unaccounted-for (MUF) was serious when tube head was made;

7, during movement pipeline, clamp, pin, rubber pad etc. all need independent keeping, fragile and lose, the operating cost height, working life is short;

The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and provide a kind of do not have burn into water-tight, without cushioning, make pipe coupling simple, long service life.

The purpose of this utility model is achieved in that it comprises salt transporting tube, and it is the connection tube head that connects between two salt transporting tubes.Be made of tube head (1), locknut (2), tube head (3), tube head (1), (3) socket-connect with salt transporting tube respectively, and locknut (2) is placed on the tube head, in order to reinforce.

The purpose of this utility model can also reach by following measure: pipe coupling adopts the nylon material compacting to form, and does not corrode with in guaranteeing to use, and once compacting forming, and its pitch is the 8-20 millimeter.

Design principle of the present utility model is: with satisfied being fastenedly connected is prerequisite, accomplishes that dismounting is convenient rapidly.The large screw pitch structure is adopted in pipe coupling.

Compared to existing technology, the utlity model has following advantage:

1, adopts nylon material to make,, fundamentally solved the very serious problem of sea salt district metal erosion to mould Dai Gang.

2, component part quantity is few, and preparation process is simple, good seal performance, and leak-down rate is low, has improved the working efficiency of pump.

3, simple and convenient assembly, time saving and energy saving, once to assemble successfully, built-up time is more over half than original saving, and maintenance rate is low.

4, during movement pipeline, need not to take care of separately accessory.

5, operating cost is low, long service life, and be more than 2 times of steel joint working life.

The drawing explanation of accompanying drawing:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the utility model linkage structure schematic representation.

Embodiment describes the utility model in detail below in conjunction with accompanying drawing.

The utility model is made up of tube head (1), locknut (2), (3) three of tube heads, and the specification of tube head (1), (3) is identical, is enclosed within the end of salt transporting tube respectively, and is with locknut (2) warp-wise that the contact position of two tube heads is fastening.Screw thread among the figure (4) is the connecting thread of tube head (1), (3) and salt transporting tube.Pitch of the present utility model is the 8-20 millimeter, and optimum value is 16 millimeters.

Claims

1, the salt transporting tube salt transporting tube road joint used in a kind of salt pan comprises salt transporting tube, it is characterized in that it is made of tube head (1), locknut (2), tube head (3), and tube head (1), (3) socket-connect with salt transporting tube respectively, and locknut (2) is placed on the tube head.

2, salt transporting tube according to claim 1 road joint is characterized in that it is formed by the nylon material compacting, and its pitch is the 8-20 millimeter.
