Abstract
The utility model discloses a pipeline joint for teaching experiments of liquid sealing, which comprises a second connection body and a first connection body, wherein the outside of the first connection body is provided with a protruding ring. A seal ring is arranged respectively on the front portion and the rear portion of the protruding ring on the first connection body. Protruding edges are arranged on the inner lateral surface of the second connection body, and the first connection body and the second connection body are stably connected through the protruding rings and the protruded edges. Therefore, the pipeline joint for the teaching experiments of liquid sealing is simple in structure, convenient in connection operation and excellent in sealing property.
Description
Technical field
The utility model relates to a kind of tubing, the liquid sealing plastic pipe connecting head of the operation that experimentizes under particularly a kind of water environment.
Background technique
Carry out in the pipeline connection technology of education experiment operation under the existing water environment, need reach the convenient and high requirement of liquid sealing property of attended operation simultaneously.
The Chinese utility model patent (reference document 1) that the patent No. is 200820168393.7, name is called " a kind of pipe coupling " discloses a kind of fastening-pressing type pipe connecting structure; It is provided with bulge loop and groove in the outside of the first pipeline connecting body and the interior survey of the second pipeline connecting body respectively, and the fastening of bulge loop and groove reaches being connected of tubing when inserting the second pipeline connecting body through the first pipeline connecting body.This mode has solved the quick purpose of connecting of pipeline, but the direct contact of plastic materials can not be satisfied the requirement that tubing is connected the liquid sealing property of the operation that experimentizes under the water environment.It is in the water environment experimental implementation or infiltration or water leakage phenomenon when hydraulic pressure reaches 1.5 standard atmospheric pressures, just can occur.
The model utility content
The utility model is the requirement that takes into account convenient and swift connection and liquid sealing property, has designed a kind of novel pipe connecting structure.
A kind of education experiment of liquid sealing is used pipe coupling; Comprise second connecting body and outside first connecting body that is provided with bulge loop; It is characterized in that: described first connecting body is respectively equipped with seal ring at the bulge loop front and rear; The described second connecting body inner side surface is provided with protruding stupefied, and said first connecting body and said second connecting body are through said bulge loop and said protruding stupefied stable the connection.
Further, described bulge loop and protruding stupefied cross section are arc.The cross section of arc helps reducing when first connecting body inserts second connecting body resistance, and increases the area of contact after bulge loop and the protruding stupefied engaging, helps the enhancing of sealability.
Further, described bulge loop and protruding stupefied edge are fillet.
Further, the surface of contact of described seal ring and bulge loop is the arc setting, increases area of contact and is beneficial to enhance seal performance.
The utility model utilizes the tension force of plastic materials to reach the tight of two connecting bodys through bulge loop with protruding stupefied engaging to be connected, and uses seal ring to strengthen its sealability, the simple structure that reaches, and processing is simple, and attended operation is convenient, the purpose that sealability is superior.
Description of drawings
Fig. 1 dissects schematic representation for the utility model apparatus structure.
Embodiment
Below in conjunction with accompanying drawing the structure of the utility model is done and to be described in further detail.
Pipeline described in the reference document 1 connects header structure and only adopts contact between plastics and the plastics to be not enough to the sealing that guarantees that pipe fitting is connected because of reasons such as plastic ageing distortion; The operation or the perhaps water leakage phenomenon that when hydraulic pressure reaches 1.5 standard atmospheric pressures, just can occur seeping water experimentize under water environment simultaneously; And when cross of a specified duration and high pressure service life, all there is the fault of leaking, influences the using effect and the life-span of entire equipment.
As shown in Figure 1, a kind of pipe coupling that improves structure comprises that first connecting body 1 and second connecting body, 2, the first connecting bodys, 1 outside are provided with bulge loop 3, and be respectively equipped with seal ring 5 at bulge loop 3 front and rears, seal ring 6, the second connecting bodys 2 inner side surfaces are provided with protruding stupefied 4.First connecting body 1 is connected with protruding stupefied 4 engagings of second connecting body 2 through bulge loop 3, and strengthens sealing through seal ring 5, seal ring 6.
The utility model is not limited to bulge loop and protruding stupefied position relation in the pipe joint structure, and all are connected with protruding stupefied engaging through bulge loop and the pipeline connecting head through seal ring enhancing sealing all falls within the scope that the utility model is asked for protection.
Claims (4)
