Abstract

The invention relates to a strong magnetic joint which comprises a joint body and a channel arranged in the joint body, wherein a magnetic bolt is inserted on the side wall of the joint body; the head part of the bolt is exposed out of the joint body; and the tail part of the bolt extends into the channel of the joint body, and a clearance is reserved between the tail part of the bolt and the inner wall of the channel. Compared with the prior art, according to the invention, the magnetic bolt is inserted into the joint, impurities in an coil channel, especially iron slag, can be automatically absorbed in the tail part of the bolt, and the efficacy of cleaning circulating media is achieved; and through arranging the joint provided by the invention in the oil channel, as long as the bolt with absorbed impurities is replaced randomly, the aims of cleaning the oil channel time to time and preventing from damaging machine elements are achieved; and the bolt is very convenient to replace and operate, and is very low in cost, and the service life of a hydraulic pump can be prolonged.

Description

A kind of strong magnetic joint

Technical field

The present invention relates to a kind of pipe joint, relate in particular to a kind of strong magnetic joint of ability impurity screening.

Background technique

If engine likens the heart of automobile to; Machine oil is like being that the blood of circulation in heart is the same so; The quality of machine oil is the key factor that can the decision engine guarantee to remain on optimum Working; Thereby oil change at regular intervals is for automobile injects fresh blood, also becomes the important operation of car maintaining.Machine oil is for engine work, has multiple performances such as lubricated, cooling, antirust, damping, maintenance be airtight, and wherein, also having some important effect is exactly cleaning action.As everyone knows, engine combustion needs gasoline and air mixing, and the air of suction engine can be carried a little impurity, dust unavoidably secretly; And can produce carbide after the mixture burns, these can be via engine oil flow, if things go on like this attached to the residue on the parts; The meeting abrasive parts using, even block the machine oil path.And general engine inner engine oil filter core can only filter minimum 25 microns particle, still continues to be trapped in the machine oil less than 25 microns particles, like metal fillings.In addition, certain expense that oil change at regular intervals can produce, and the trouble that more changes jobs also, this also causes and changes operation is not very frequent.Thereby, press for a kind of simple way and solve this problem.

On the other hand, the application of pipe joint in oil, liquid delivery line connect is very extensive, and be common like two pass joints, tee union, multiple-pass joint or the like.In hydraulic channel, if contain more impurity in the oil, such as iron filings, its oil hydraulic pump that can wear and tear, even choked flow circulation passage directly influence the normal operation of oil hydraulic pump, and oil hydraulic pump cost an arm and a leg, and should avoid the damage of oil hydraulic pump as far as possible.

Summary of the invention

Technical problem to be solved by this invention is to the existing technology present situation a kind of strong magnetic joint to be provided; It has strong magnetic effect, can hold the metal fillings in the circulation medium, the cleaning circulation medium; Avoid damaging parts, and can change at any time and pollute parts, cheap.

The present invention solves the problems of the technologies described above the technological scheme that is adopted: this strong magnetic joint; Comprise joint body and be arranged on the passage in the joint body; It is characterized in that: be inserted with a magnetic bolt on the sidewall of said joint body; The head of this bolt exposes to outside the joint body, and the afterbody of bolt extend among the passage of joint body, and leaves the gap between the inwall of afterbody and passage.

Preferably, said joint body is a tee union,, has three passages in the joint body that is, and said bolt is arranged on the intersection of three passages;

Preferably, said joint body is the curved pass joints of one 90 degree, and said bolt is arranged on the bending place of passage.

Compared with prior art, the present invention inserts a magnetic bolt in joint, make in the oil circuit impurity particularly iron filings can be adsorbed on the afterbody of this bolt automatically, reach the effect of cleaning circulation medium; Through this joint of the present invention is set in oil circuit; As long as change the bolt that this is adsorbed with impurity at any time; Can reach the purpose that cleans oil circuit constantly, avoids damaging parts, compared with the more change engine oil in the car maintaining, operation is very easy, price is very cheap in bolt replacing of the present invention; Can increase the working life of oil hydraulic pump, and overall structure of the present invention very simple, be easy to apply.

Embodiment

Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.

Embodiment one:

Like Fig. 1, shown in Figure 2, this strong magnetic joint comprises joint body 1 and is arranged on the passage 11 in the joint body 1;

In the present embodiment, said joint body 1 is a tee union,, has three passages 11 in the joint body 1 that is;

Be inserted with a magnetic bolt 2 on the sidewall of joint body 1; This bolt 2 is positioned at the central intersection of three passages 11; The head 21 of this bolt 2 exposes to outside the joint body 1; And the afterbody 22 of bolt 2 extend among the passage 11 of joint body 1, and leaves the gap between the inwall of afterbody 22 and passage 11.

Embodiment two:

As Fig. 3, shown in Figure 4 be embodiments of the invention two, itself and embodiment's one distinctive points is: joint body 1 is the curved pass joints of one 90 degree in the present embodiment, only has a circulation passage 12, and said bolt 2 is arranged on the bending place of passage 12.

Claims

1. one kind strong magnetic joint; Comprise joint body and be arranged on the passage in the joint body; It is characterized in that: be inserted with a magnetic bolt on the sidewall of said joint body; The head of this bolt exposes to outside the joint body, and the afterbody of bolt extend among the passage of joint body, and leaves the gap between the inwall of afterbody and passage.

2. strong magnetic joint as claimed in claim 1 is characterized in that: said joint body is a tee union,, has three passages in the joint body that is, and said bolt is arranged on the intersection of three passages.
