Abstract
The utility model provides a movable joint for encapsulation, which comprises a fixed pipe, a rotary pipe and a connection piece, wherein, a first connection flange and a second connection flange arearranged on the fixed pipe and the rotary pipe respectively, external threads are formed on the outer edge of the first connection flange, the connection piece comprises a connection barrel and a locking nut, a third flange is arranged at one end of the connection barrel, the inside diameter of the third flange is larger than the outside diameter of the rotary pipe yet smaller than the outside diameter of the second connection flange, the connection barrel is sleeved on the rotary pipe and screwed on the external threads on the second connection flange of the fixed pipe so as to enable the fixed pipe to be connected with the rotary pipe, a first sealing gasket is arranged between the third and the second connection flanges, a second sealing gasket is arranged between the first and the second connection flanges, and the locking nut is screwed on the external threads of the first connection flange so as to lock the connection barrel tightly. After the locking nut is locked tightly with acertain torque, the tetrafluoroethylene sealing gaskets are capable of sealing, and the rotary pipe can rotate.
Description
Technical field
The utility model belongs to the adaptor union in the chemical machinery field, relates to a kind of can movable joint.
Background technology
In general chemical enterprise, often need carry out liquid material is filled to work in the regular barrel, when after one barrel of can finishes, switching to another barrel, need could utilize handbarrow that bucket is removed packing mouthful rotation 90～180 degree.Yet leak through regular meeting at the place at the rotary course center tap, and the liquid of water clock usually can pollute new packing barrel, because the cleaning difficulty has a strong impact on the outward appearance of packing, even causes customer complaint and economic compensation.
The utility model content
Technical problem to be solved in the utility model is to leak at rotary course through regular meeting at the existing joint that is used for can, and provides a kind of good airproof performance, the can movable joint of anti-leak.
The utility model solves this technical problem by following scheme:
A kind of can movable joint comprises stationary pipes, swivelling pipe and attaching parts, is respectively arranged with first butt flange and second butt flange on stationary pipes and swivelling pipe, and wherein the outer rim of first butt flange is provided with outside thread.Described attaching parts comprises that one connects a swivel nut and a jam nut, and an end of described connection swivel nut is provided with the 3rd flange, and wherein the internal diameter of the 3rd flange is greater than the external diameter of swivelling pipe but less than the external diameter of second butt flange; Described connection swivel nut is enclosed within on the described swivelling pipe and is threaded onto on the outside thread of second butt flange of described stationary pipes, and stationary pipes is connected with swivelling pipe; Between the 3rd flange and second butt flange, be provided with first packing seal, between first butt flange and second butt flange, be provided with second packing seal; Jam nut is threaded onto on the outside thread of described first butt flange, connects swivel nut with locking.
First packing seal of the present utility model and second packing seal all adopt the tetrafluoroethylene material to make.
The utility model adopts as above structure, especially is being provided with first packing seal between the 3rd flange and second butt flange, is provided with second packing seal between first butt flange and second butt flange; Promptly guarantee the rotation of swivelling pipe, guaranteed swivelling pipe and the sealing that is connected between swivel nut, the stationary pipes again.
The utility model utilizes the compressibility of tetrafluoroethylene gasket seal and wear-resistant, and the resistant to corrosion characteristics are worked as jam nut, after locking with certain moment.The tetrafluoroethylene gasket seal just can play the leak free effect, and swivelling pipe can also rotate simultaneously.Screwed retaining ring can prevent that jam nut is loosening in long-term motion, causes leakage.
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is the structural representation of embodiment 1 described packing movable joint.
The specific embodiment
Referring to Fig. 1, a kind of can movable joint comprises stationary pipes 1, swivelling pipe 4 and attaching parts, and the outer rim that is respectively arranged with first butt flange 11 and second butt flange, 41, the first butt flanges 11 on stationary pipes 1 and swivelling pipe 4 is provided with outside thread 12.Attaching parts comprises that one connects a swivel nut 6 and a jam nut 2, and an end that connects swivel nut 6 is provided with the 3rd flange 61, and wherein the internal diameter of the 3rd flange 61 is greater than the external diameter of swivelling pipe 4 but less than second butt flange, 61 external diameters; Connect swivel nut 6 and be enclosed within on the swivelling pipe 4 and be threaded onto on the outside thread 12 of second butt flange 11 of stationary pipes 1, stationary pipes 1 is connected with swivelling pipe 4; Between the end face of the end face of the 3rd flange 61 and second butt flange 41, be provided with first packing seal 5, first butt flange 11 be provided with second packing seal 3 between the end face of end face and second butt flange 41; Jam nut 2 is threaded onto on the outside thread 12 of first butt flange 11, connects swivel nut 6 with locking.First packing seal 5 and second packing seal 3 all adopt the tetrafluoroethylene material to make.
During use, only need tighten according to the direction shown on the accompanying drawing and connect swivel nut 6 and get final product, liquid material is according to direction transmission on the accompanying drawing, when needs rotation packing mouthful, only needs rotation swivelling pipe 4 to get final product.
Because first packing seal 5 and second packing seal 3 often are in movable Frotteurism, so the utility model is coated with one deck grease on first packing seal 5 and surface that second packing seal 3 contacts.In addition in order to make can movable joint structure compactness, it is the screw thread of M40 * 0.75 that the connection swivel nut 6 of present embodiment adopts specification, so that anti-leak result is better, certainly for the general liquid material of can, only need use 304 materials to make and just can reach good anti-leak result, the described packing movable joint of present embodiment is mainly used in the active joint that manual packing barrel is used.
Should be appreciated that those skilled in the art can make various changes or modifications the utility model after having read instruction foregoing of the present utility model, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
