The existing side interface is a round tube with a lower clamping seat, the bottom clamping seat and the round tube connected with the bottom clamping seat are matched and connected with an opening on the side wall of the membrane shell, and a groove and a round tube opening on the upper part are connected with a clamping hoop. Due to the deviation of the opening precision of the membrane shell and the influence of temperature and pressure on the membrane shell in the using process, expansion and contraction can occur, and position deviation is generated between the side interface of the membrane shell and the interface of a pipeline or other membrane shells. This deviation leads to membrane shell side opening to receive extra load, influences the sealed effect of side mouth, causes the local layering of membrane shell trompil department even to lead to the membrane shell to become invalid.
Therefore, it is desirable to design an eccentric side port to solve the above-mentioned problems.
Disclosure of Invention
The invention aims to provide an eccentric side port, which solves the problem of position deviation of a side port of a membrane shell or the problem of leakage caused by extra load borne by the side port and the opening part of the membrane shell due to interface distance deviation caused by expansion and contraction of the membrane shell when pressure and temperature change.
In order to achieve the purpose, the invention is realized by the following technical scheme: the eccentric side port is at least composed of a side port main body, a side port fastening nut and a sealing ring, a male thread in threaded connection with the side port fastening nut is arranged outside the side port main body, the cylindrical surface matched with the membrane shell and the interface cylindrical surface connected with the clamping hoop are not coaxial, and an eccentric distance t is arranged between the two axes.
Preferably, the eccentric side port is connected and installed in the same manner as a general side port.
The assembling and debugging method of the eccentric side port comprises the following steps:
a mouth cooperation is put with the reaming of membrane shell lateral wall trompil to side mouthful main part bottom cassette, and the cooperation of simultaneously side mouthful main part bottom outer cylinder face and membrane shell lateral wall trompil to with the side mouthful fastening nut back of the body tight, it is sealed with the sealing washer to put mouthful department at bottom cassette and membrane shell lateral wall trompil, accomplish above-mentioned two eccentric side mouthful of installation backs, through rotatory side mouthful main part, just can adjust the eccentric side mouthful installation distance of membrane shell, establish the axial lead distance between two eccentric side mouths and be P, make it can freely adjust between P-2t and P +2 t.
The invention provides an eccentric side port. The method has the following beneficial effects:
1. the eccentric side port provided by the invention is suitable for various installation conditions, particularly for the condition that the interval between the side holes of the membrane shell or the installation size of a field pipeline has deviation connection. The installation size can be adjusted through the rotation of side interface, or the automatic adaptation because of the interface position deviation that pipeline inflation caused, and do not cause the clamp to bear extra load or take place distortion because of this deviation, lead to sealing failure, take place the seepage.
