Description
Technical field
This utility model belongs to car air-conditioner technical field, is specifically related to a kind of coach air conditioner pipeline end face radially double sealing structure.
Background technology
Leakage to air-conditioning duct joint occurs more frequent, causing air-conditioning fault rate higher, the most effective method does not solves this problem, can only be by optimizing sealing means, reduce the leakage between pipe joint as far as possible so that it is leakage rate is acceptable in life cycle.The pipeline sealing means that coach air conditioner is conventional at present has: end face seal, radial seal, biradial seal.
The principle of radial seal is to reach sealing effectiveness with respective tube joint inner cylinder face by coordinating by O RunddichtringO, advantage is that the sealing effectiveness of O RunddichtringO is not affected by nut and nut screwing clamping degree in a certain degree, O RunddichtringO is hardly damaged, good sealing effect；Shortcoming is owing to respective tube joint easily makes sealing inner cylinder face produce certain ovality in processing and brazing process, and causes the slow leakage of line connection.
The principle of end face seal is to make O RunddichtringO interference fit between pipeline is connected reach sealing effectiveness by the nut between pipeline connects under certain pretightning force with joint, when pretightning force is appropriate, good sealing effectiveness and the impact of leakiness not receiver pipe connection ovality can be played, but O RunddichtringO damages by pressure or malcompression when pretightning force is incorrect, produce slow leakage.
Biradial seals identical with single radial seal principle, the most protection together.
Three of the above seals the generation that structure cannot be avoided leaking slowly.
Utility model content
In order to solve to exist in existing sealing structure the technical problem of slow leakage, this utility model provides a kind of coach air conditioner pipeline end face radially double sealing structure, this structure uses end face to add radial direction double and seals, sealing effectiveness can be obtained at significantly more efficient raising pipe joint, reduce coolant to leak slowly, and design ingenious, simple and practical.
For achieving the above object, the technical scheme that this utility model is taked is as follows:
This utility model provides a kind of coach air conditioner pipeline end face radially double sealing structure, it includes pipe joint and pipeline spin slot, pipe joint is set in the top of pipeline spin slot, the lower end of described pipe joint is machined with pipe seal inclined-plane, the angle sealing inclined-plane and horizontal plane is 30 ° ~ 45 °, the upper periphery of pipeline spin slot offers radial seal groove, the root periphery of pipeline spin slot offers end face seal groove, O RunddichtringO I it is filled with in radial seal groove between pipe joint and pipeline spin slot, O RunddichtringO II it is filled with in end face seal groove between pipe joint and pipeline spin slot；Fixed by locking nut between described pipe joint and pipeline spin slot.
According to above-mentioned coach air conditioner pipeline end face radially double sealing structure, the periphery of described pipe joint is provided with external screw thread, and the periphery of pipe joint is arranged with tapped locking nut.
Described sealing inclined-plane and the angle preferably 30 ° of horizontal plane.
The outer surface pier that described pipeline spin slot is in the interface end of pipeline goes out spin slot.
Compared with prior art, the beneficial effect that this utility model obtains:
1. this utility model structure includes pipe joint and pipeline spin slot, pipe joint is set in the top of pipeline spin slot, the lower end of described pipe joint is machined with pipe seal inclined-plane, the angle sealing inclined-plane and horizontal plane is 30 °, the upper periphery of pipeline spin slot offers radial seal groove, the root periphery of pipeline spin slot offers end face seal groove, it is filled with O RunddichtringO I in radial seal groove between pipe joint and pipeline spin slot, in the end face seal groove between pipe joint and pipeline spin slot, is filled with O RunddichtringO II；Fixed by locking nut between described pipe joint and pipeline spin slot；In structure, pipeline spin slot structure passes through mould machine-shaping, it is easy to ensure machining accuracy；Radial seal in structure selects to fill O RunddichtringO I in general radial seal groove and seals, root is that newly-increased end face seal selects to fill in general end face seal groove O RunddichtringO II and carries out end face seal, O RunddichtringO I and O RunddichtringO II and belong to the O RunddichtringO of different size.
2. this utility model simple in construction, design ingenious, convenient and practical, it is possible to obtain sealing effectiveness at significantly more efficient raising pipe joint, reduce coolant and leak slowly.
3. this utility model uses said structure, can bring certain economic benefit and social benefit to enterprise.
