Utility model content
The purpose of this utility model is to provide a kind of piping connection sealing structures, to solve to propose in above-mentioned background technology The problem of.
To achieve the above object, the utility model provides the following technical solutions:A kind of piping connection sealing structure, including: Fittings body one, fittings body two, planar sealing pad, big nut are provided with and the internal thread phase on big nut on the fittings body one The external screw thread of cooperation, one front end center position of fittings body are provided with the guide section playing the guiding role, and one front end outer side of fittings body is set It is equipped with the clamping plane for compressing sealing function, two end of head body is provided with the shaft shoulder structure coordinated with big nut, head Two end of body is axial compression plane, and the big nut is socketed on fittings body two, and affixed by screw thread and fittings body one, The planar sealing pad is clamped by fittings body one and fittings body two.
Further, it is provided with clamping plane on the fittings body one.
Further, on the big nut on be provided with clamping plane.
Further, the planar sealing pad is made of high performance corrosion-proof sealing material, the thickness of planar sealing pad It is adjustable according to medium.
Compared with prior art, the utility model has the beneficial effects that:
(1) it is proved through application practice, this sealing structure performance is good, and bearing capacity is apparently higher than linear sealing, sealing performance It is unattenuated;
(2) this structure assemblyization degree is high, and installation operation is convenient, time and labour saving;
(3) be both designed on this fittings body one with the matched external screw thread of internal thread on big nut, be also devised with and led To the clamping plane of the guide section and compression sealing function of effect;Be designed on fittings body two can mounting plane gasket axis Shoulder structure is also configured with axial compression plane, while shaft shoulder structure also coordinates with big nut;
(4) according to the property of sealing medium, planar sealing pad can be adjusted flexibly in the decrement of determining planar sealing pad Thickness, and other parts do not have to change;
(5) design of guide section both ensure that positioning to just accurate, to screw thread due to concentricity difference when in turn avoiding tightening Damage;
(6) planar sealing pad is made of high performance corrosion-proof sealing material, does not need to change;
(7) delivery pipe at structure both ends does not have to rotation when using, and avoids the damage to delivery pipe;
(8) this infrastructure cost is low, cheap.
The piping connection sealing structure of the utility model, sealing and bearing capacity are high, degree of integration height, province easy for installation Work, planar sealing pad decrement is adjustable, free of replacement, not damaged to screw thread and delivery pipe, environmental protection, cheap.
