Abstract
The utility model relates to a pressure vessel fast open gear-matched type structure which belongs to the technical field of a pressure vessel and comprises a lathe dog arranged at the end part of a tube body and a door closure flange arranged at the end part of a door closure, wherein lathe dog teeth are arranged along the circumference of the lathe dog, door closure teeth are arranged along the circumference of the door closure flange and are composed of first teeth and secondary teeth which are arranged alternatively, the length a of the first teeth is larger than the length b of the secondary teeth, a step is arranged at one side where the first teeth are arranged on a pressure releasing, and the length c of the crest of the first teeth is equal to that of the secondary teeth. In the process that the door closure is opened, the utility model can rapidly and thoroughly release the excess pressure, can improved the production efficiency of the pressure vessel, and has reliable use and work reliability.
Description
Technical field
The utility model relates to a kind of pressure vessel of quick opening door tooth-type structure, belongs to the pressure vessel technology field that is used for building materials, chemical industry, light industry, weaving etc.
Background technique
Need to feed the working medium of certain pressure in the pressurized container work, goods in the container are handled, and door-opening pressure vessel is owing to easy to operate, so in each industrial field extensive use.The door closure of door-opening pressure vessel is connected with the cylindrical shell end, all adopt door closure tooth on the door closure flange and the clamp teeth on the body end surface clip to be connected with a joggle, and the end face between door closure flange and the clip is provided with seal ring, after the clip engagement of door closure flange and body end surface puts in place, feed pressure in the container, make door closure flange and clip end face seal, have simple to operate, compact structure, reliable sealing characteristics.When avoiding door closure to open, residual pressure ejects door closure and causes danger in the container, on the door closure tooth, be provided with at present special-purpose gas pressure relief slot, before opening door closure, with door closure rotation and with clip also under the state of clamping, the residual pressure of internal tank is discharged,, also exist a defective that interior overbottom pressure can not be discharged fast though can residual pressure be discharged by the gas pressure relief slot on the door closure tooth.
Summary of the invention
The purpose of this utility model provides a kind ofly can let out overbottom pressure in the cylindrical shell pressure vessel of quick opening door tooth-type structure of removing fast.
The utility model is that the technological scheme that achieves the above object is: a kind of pressure vessel of quick opening door tooth-type structure, comprise the clip that is arranged on the cylindrical shell end and the door closure flange of door closure end, clip is along being circumferentially with clamp teeth, the door closure flange is along being circumferentially with the door closure tooth, it is characterized in that: described door closure tooth is made of first tooth and second tooth that are provided with at interval, the long a of the tooth of first tooth is greater than the long b of the tooth of second tooth, and first tooth is positioned at pressure release one side and is provided with step, the tooth top length c of first tooth and the second tooth tooth top equal in length.
The utility model is by improving the door closure tooth, the door closure tooth is made of first tooth and second tooth, though the long a of the tooth of first tooth greater than the long b of the tooth of second tooth, owing to be provided with step in the first tooth pressure release, one side, makes the tooth top length c and the second tooth tooth top equal in length of first tooth.During work, door closure tooth and clamp teeth are fitted one by one, and door closure and cylindrical shell are tightly connected reliably.And when the container pressure release, before opening door closure, when door closure rotates to the step position of first tooth, though second tooth on the door closure tooth and the clamp teeth of applying break away from, but door closure flange and clip still are in coupled condition, at this moment, the residual pressure of inner barrel discharges by the backlash of the clamp teeth and second tooth, and when door closure continues rotation, along with the increase gradually of backlash, in opening the process of door closure, overbottom pressure can fast, thoroughly be let out remove, use reliably, can improve production of pressure container efficient and functional reliability.
Description of drawings
Below in conjunction with accompanying drawing enforcement of the present utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the partial structurtes schematic representation of door closure tooth.
Fig. 3 is that the A of Fig. 2 is to the structure for amplifying schematic representation.
Fig. 4 is that the B-B of Fig. 2 analyses and observe the structure for amplifying schematic representation.
Wherein: 1-door closure, 2-door closure flange, 2-1-first tooth, 2-2-second tooth, 2-3-step, 3-clip, 3-1-clamp teeth, 4-seal ring, 5-cylindrical shell.
Embodiment
See shown in Fig. 1～4, pressure vessel of quick opening door tooth-type structure of the present utility model comprises the clip 3 that is arranged on cylindrical shell 5 ends and the door closure flange 2 of door closure 1 end, and clip 3 is along being circumferentially with clamp teeth 3-1, door closure flange 2 is along being circumferentially with the door closure tooth, and clamp teeth 3-1 is connected with door closure increment face.See shown in Fig. 2,3, the utility model door closure tooth is made of the first tooth 2-1 and the second tooth 2-2 that are provided with at interval, the first tooth 2-1 and the second tooth 2-2 be uniform be arranged on door closure flange 2 circumferentially, and the long a of the tooth of the first tooth 2-1 is greater than the long b of the tooth of the second tooth 2-2, and the first tooth 2-1 is positioned at pressure release one side and is provided with step 2-3, and the tooth top length c of the first tooth 2-1 is that the long b of tooth equates with the second tooth 2-2 tooth top length.Equally, the clamp teeth 3-1 on the cylindrical shell 5 end clips 3 is the same with conventional structure, lacks identical length together along circumferential each clamp teeth and tooth, and it is identical with the long a of first tooth of door closure tooth that this tooth lacks length.
During work, the first tooth 2-1 and the second tooth 2-2 on the door closure tooth fit one by one with clamp teeth 3-1 respectively, and the pressure in the cylindrical shell promotes door closure and seal ring 4, makes the seal ring 4 that is installed on the clip be fitted in door closure flange 2 end faces, form self-energized seal.After container work finishes, at first by the Decompression valves container inner pressure of releasing, when pressure is designated as zero, seal ring 4 withdrawals on the clip 3, rotation door closure 1, door closure tooth on the door closure flange 2 and clamp teeth 3-1 be slide relative lentamente, when door closure 1 rotates to the step 2-3 of the first tooth 2-1, the inner minimum overbottom pressure effect of door closure flange 2 receptors and axially moving along clip, second all on the door closure tooth tooth 2-2 throw off from fit-state, overbottom pressure is removed along circumferentially discharging gradually to let out by the backlash, guarantees container operation safety, reliable.The gap of continuing between rotation door closure 1, the second tooth 2-2 and the clamp teeth 3-1 increases gradually, overbottom pressure in the container is thoroughly let out remove fast, increases work efficiency under the safe and reliable prerequisite of container operation having guaranteed.Throw off fully until the first tooth 2-1 and clamp teeth 3-1 when door closure 1 rotation, open door closure 1.The utility model can be by the manual or automatic control gate lid flange first tooth 2-1 step 2-3 position the time time of being stopped.
