Detailed Description

The present application will now be described in further detail with reference to the drawings, it should be noted that the following detailed description is given for illustrative purposes only and is not to be construed as limiting the scope of the present application, as those skilled in the art will be able to make numerous insubstantial modifications and adaptations to the present application based on the above disclosure.

Referring to fig. 1 to 5, a universal top steam drainage four-way pipe structure includes an outer pipe 1 and an inner pipe 2, the outer pipe 1 is a four-way pipe structure, two of the two pipes are located on a same straight line, the other two pipes are respectively arranged on two sides of the straight line, a flow area of the inner pipe 2 is smaller than that of the outer pipe 1 on the same straight line, two clamping edges 21 are formed on an outer surface of the inner pipe 2 along a length direction, a plug 22 is formed at one end of the inner pipe 2, the inner pipe 2 can be inserted into the outer pipe 1 along the two pipes on the same straight line, and after the plug is inserted, the outer surface of the inner pipe 2 is in sealing contact with an inner surface of the outer pipe 1 through the two clamping edges 21, and the plug 22 plugs a gap between the inner pipe 2 and the outer pipe 1. The inner pipe body 2 divides the interior of the outer pipe body 1 into three independent channels, wherein one channel is a linear channel (namely the channel inside the inner pipe body 2), the other two channels are channels formed by a gap between the inner pipe body 2 and the outer pipe body 1, and the two channels are respectively communicated with the two channels on the side edge of the outer pipe body 1.

In the invention, the cross section of the inner tube body 2 is oval or rhombic, but also can be in other irregular shapes, and the cross section of the outer tube body 1 is circular. The plug 22 is circular, and the outer diameter of the plug 22 is greater than or equal to the outer diameter of the outer tube 1.

In the invention, a convex ring 23 is formed on the side surface of the plug 22 for plugging, the outer diameter of the convex ring 23 is smaller than the outer diameter of the plug 22, the inner diameter of the convex ring 23 is larger than the inner diameter of the plug 22, a sealing ring 3 is sleeved on the inner pipe body 2, a plurality of pin pieces 31 are embedded on the side surface of the sealing ring 3, the pin pieces 31 are uniformly arranged along the radial direction of the sealing ring 3, a small gap is reserved between adjacent pin pieces 31, when the gap is plugged by the plug 22, the sealing ring 3 is positioned between the plug 22 and the end head of the outer pipe body 1, and the sealing ring 3 is in line contact with the convex ring 23 through the side surface with the pin pieces 31, namely, a contact line.

One side of the sealing ring 3 is in contact with the end surface of the outer pipe body 1, the other side is in line contact with the convex ring 23, and each pin sheet 31 can rotate by taking the convex ring 23 as a fulcrum, when the outer pipe body 1 has a deviation trend relative to the inner pipe body 2 or the sealing surface is impacted by high-pressure water, the sealing ring 3 can be always tightly attached to the end surface of the outer pipe body 1, the sealing property is ensured, the principle lies in that the arrangement of the pin sheets 31 enables all positions on the surface of the sealing ring 3 to generate a linkage effect, when a certain point is extruded or impacted to have a contraction trend, the point corresponding to the point can be outwards expanded under the torsion action of the convex ring 23, and due to the blocking effect of the contact surface, the expansion cannot be realized, so that the extruded point cannot be contracted, the tight contact of each point is always.

Specifically, the cross section of the protruding ring 23 is semicircular, and the circumferential line of the protruding ring 23 contacting the seal ring 3 is located at the middle position between the outer ring and the inner ring of the seal ring 3, that is, at the middle position of each pin piece 31. The pin pieces 31 are made of metal, such as steel, iron, and the like, and the outer end of each pin piece 31 is flush with the outer ring of the seal ring 3, and the inner end of each pin piece 31 is flush with the inner ring of the seal ring 3.

In the invention, the clamping edge 21 is composed of elastic rubber columns which are arranged along a straight line, the cross sections of the elastic rubber columns are square, the bottoms of the elastic rubber columns are bonded with the inner pipe body 2, all the elastic rubber columns are obliquely arranged and are obliquely opposite to the inserting direction of the inner pipe body 2, and adjacent elastic rubber columns are obliquely and movably lapped. The acute angle included angle between the elastic rubber column and the inner tube body 2 is 60-70 degrees. The internal surfaces of two passageways on the same straight line of outer body 1 are equipped with the draw-in groove portion 11 that matches with joint limit 21, and when interior body 2 inserted the back, joint limit 21 was located draw-in groove portion 11 and was connected with draw-in groove portion 11 interference.

After the clamping edge 21 is inserted into the clamping groove part 11, the top of the elastic rubber column is in interference contact with the bottom of the clamping groove part 11, and the side edge of the elastic rubber column is also in close contact with the side edge of the clamping groove part 11, so that the sealing property is ensured; in addition, the elastic rubber column that the slope set up is convenient for insert, and can't reverse take out after inserting, because take out and can make the elastic rubber column produce deformation and vertical gradually, length increase leads to inseparabler with the laminating of draw-in groove portion 11, and static friction further increases, so can't take out under the effect of normal force, has guaranteed the stability of structure. Preferably, the top surface of the elastic rubber column can be subjected to surface treatment, so that the friction coefficient of the elastic rubber column is increased, and the stability is further improved.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
