Description

Cutting ferrule type high-sealing straight-through joint Technical Field The utility model relates to the technical field of pipeline connectors, in particular to the technical field of a clamping sleeve type high-sealing straight-through connector. Background The straight joint is mainly used for straight line connection, maintains the linearity and the unobstructed property of a fluid transmission path, and is suitable for occasions requiring high-purity fluid transmission, corrosion resistance and high temperature resistance, such as the fields ‌ of chemical industry, medicine, food processing and the like. At present, the existing straight-through joint is usually provided with a loose interface, so that water leakage is caused, and if the joint is not installed in place, the joint is easy to cause the problem that later maintenance is needed, so that the service life is shorter. For solving the problem that proposes among the above-mentioned technique, for example, application number CN202123404657.9 discloses a leak protection formula through joint, including through joint and connecting pipe, through joint surface welding has the connecting plate, the connecting plate inside callipers is equipped with the clamp plate, connecting pipe outside cover is equipped with lock nut, and connecting pipe outside cover is equipped with the sealing ring, and through joint one end inboard cover is equipped with the packing ring, and through joint inside welding has the baffle, and through joint one end inside callipers is equipped with presses the cover, it has the connecting rod to press cover one end welding, connecting rod one end welding has the push pedal, and connecting rod surface cover is equipped with the spring, and connecting rod surface still overlaps and is equipped with sealed the pad, and this through joint can be effectively fixed with the connecting water pipe after connecting, avoids the joint to produce rotatoryly because of the vibrations, leads to the joint not hard up. However, the sealing performance of the structure is generally poor, the compression resistance effect is poor, the straight-through joint is always in a high-pressure state, and the phenomenon that a pipeline falls off from the joint to cause serious accidents is extremely easy to occur. For solving the problem that proposes in the above-mentioned technique, for example, application number CN202420071982.2 discloses the explosion-proof through joint of resistance to compression, including joint body and support sleeve, support sleeve's both sides outer wall equal fixedly connected with toper sleeve, threaded groove has all been seted up to toper sheathed tube one side outer wall, the equal sliding connection of both sides inner wall of joint body has sealing washer, the equal fixedly connected with screwed connection pipe of one side outer wall of sealing washer, support sleeve's outer wall fixedly connected with strengthening rib, the equal fixedly connected with resistance to compression sleeve of strengthening rib through being provided with joint body, resistance to compression sleeve, support sleeve, toper sleeve and strengthening rib, the strengthening rib that support sleeve outer wall set up and with the resistance to compression sleeve of joint body inner wall further increase structure resistance to compression effect, set up the thread groove in toper sleeve both sides, make it connect screwed connection pipe and sealing washer in both sides through the screw thread, prevent that the pressure from revealing improves whole resistance to compression performance, and the sealing performance is better to avoid the pressure to reveal influence resistance to compression performance, and joint body inside is provided with the resistance to compression structure, improves resistance to compression effect. However, the above structure still has the following drawbacks: Be equipped with the screw thread groove on the cutting ferrule in the above-mentioned structure, make it pass through the screw thread and connect screwed connection pipe and sealing washer in both sides, but only adopt the screw connection to use the condition that the joint strength is not enough easily to appear down for a long time, thereby make the pipeline easily take place not hard up with the joint body and influence the leakproofness of junction.
