Abstract
The utility model provides an insertion rotating type transfusion hose connector sealing ring. A groove is arranged on the upper portion of the sealing ring. The lower portion of the section of the sealing ring is L-shaped, the upper portion of the section of the sealing ring is V-shaped, and the whole sealing ring section is y-shaped. The insertion rotating type transfusion hose connector sealing ring mainly solves the problems in the prior art that a matching gap of two sealing rings is not easy to control, if the matching gap is too small, screwing in is effort-consuming, and if the matching gap is too large, sealing is not reliable, leaking is caused and the like. The basic shape of the section of the sealing ring is y, effective sealing area and elastic deformation between the two sealing rings are effectively increased, pressing of the two connector bodies is effortless, sealing performance is good, and sealing is reliable.
Description
Technical field
The utility model relates to a kind of seal ring, and particularly a kind of seal ring that is used for larger caliber inserting turning infusion tube joint belongs to the joint sealing field.
Background technique
As everyone knows, inserting turning infusion tube joint is to be screwed in each other by two fittings bodies, comes the compression joint seal ring through controlling relative screw-in depth, thereby the realization seal request.And present widely used inserting turning hose coupling seal form, the bad control of ubiquity two seal ring matching gaps, matching gap is too small, because the seal ring selected materials can not be too soft, to such an extent as to during the butt joint of two fittings bodies, screw in very effort each other; Excesssive gap during the butt joint of two fittings bodies, exists sealing unreliable, phenomenons such as leakage.This has just caused butt joint body requirement on machining accuracy height in the actual production, the shortcoming that cost increases.For small-bore joint, machining accuracy is easier to control, but caliber size big after because lathe, the making error of frock etc. is inevitable, so difficulty of processing is bigger.
Summary of the invention
The purpose of the utility model is to provide a kind of sealing reliable, makes two fittings bodies screw in comparison labour-saving inserting turning infusion tube joint sealing circle each other.
The technological scheme of the utility model is: the top of said seal ring is provided with groove; The bottom of said seal ring sectional shape is L-shaped, and top is V-shaped, and global shape is y-shaped.
Said seal ring bottom is provided with comfortable groove, and dismounting is more convenient, can also effectively overcome the machining deformation of sealing mounting groove, guarantees that seal ring can accurately be in place.
The inner circumference of said seal ring is provided with groove; Said groove comprises the little inclined-plane that sets gradually, big inclined-plane, boss from top to bottom; The boss bottom is provided with first curve slope; Little inclined-plane, big inclined-plane, boss corresponding part are by the inclined-plane and face formed lip directly on the excircle of said seal ring and the inner circumference; The excircle of said seal ring is second curve slope of corresponding setting with the inner circumference first curve slope corresponding part.
The curve slope of bottom two arranged outside of the utility model helps the installation of seal ring.
The boss of one arranged outside of the utility model can be fixed in the mounting groove after seal ring is installed more closely, can not rotate, and more can not fall down easily.
The big inclined-plane of one arranged outside of the utility model; Be used for cooperating mounting groove, the big inclined-plane lateral end seal of having a mind to make seal ring is towards extrapolation, after two fittings bodies are screwed; Two sealing surfaces are under the acting in conjunction of screw impacting force and inside water pressure pressure; Return to normal sealing state, guaranteed that effectively the contact of two sealing surfaces is tightr, sealability is better.
The little inclined-plane of relative set above the big inclined-plane of the utility model; Can change the force direction of inside water pressure and increase the active force area of water pressure accordingly, make two sealing surfaces under hydraulic action, contact tightr; Simultaneously; Hydraulic pressure is big more within the specific limits, and it is tighter that two sealing surfaces are pressed, and sealing effect is better.
The utility model is designed to " y " type to the basic shape of seal ring, and " y " type structure has effectively increased the effective sealing area between two seal rings, has overcome the concentricity matching gap requirement of fittings body; And; Two seal rings are compressing under the sealing state, and the centre has formed the spacious zone of a rhombus, have increased the resiliently deformable of seal ring simultaneously; More laborsaving when two fittings bodies are compressed, and sealability is better.
