The valve is used for the bottom stowage and the draining of offshore oil platforms, ships, naval vessels and the like to ensure mooring and navigation safety.
Description
(1) technical field
Structural type of the present utility model relates to stop valve and stopcock.Its function pattern is a two-way valve, is installed in marine portable oil platform, boats and ships, naval vessels isoballast bilge portion, is used for into, draining.It particularly is a kind of stopcock combination brake switch and proporting.
(2) background technique
Marine portable oil platform, boats and ships, naval vessels isoballast cabin are advanced, the draining two-way valve, and at present the most frequently used has three kinds: right-angle type stop valve, right-angle type stop valve and one way stop peturn valve equipped, end and non-return integral type cabin-bottom valve.Its shortcoming is respectively: poor sealing performance, easily by foreign material jam in the seawater, easily leak, and the water in the ballast tank can not all emit.These fatal shortcomings are major safety risks of platform, boats and ships, naval vessels.Patent documentation by retrieval, have two pieces a little less than relevant documents, number of patent application is 200510045517.3 and 200520125587.5, than above-mentioned prior art certain innovation is arranged.Though have double-sealing, anti-jam, leakage proof simultaneously, discharge four functions entirely,, still can not realize these functions very reliably because there are some defectives in structural design.One of its defective is: the interior edge face of seal ring 10 is its important faces that are sealed and matched, owing to be easy to deflection during seal ring 10 assembling, produce the gap and loses seal action, and double-sealing has just lost primary seal.Two of defective is: connect with the guide assembly parts between expanding tense machine 7, valve plate 8, guide plate 11 threes.Perhaps, the routine environment is out of question on land, but sinks to for a long time in the seawater, is easy to adhere to the shell marine growth herein, and is difficult to remove, and causes commentaries on classics, slip to be stuck, and this valve can not open or cut out.If poor sealing opens and closes malfunctioningly, just there is not the leakage proof function certainly.Three of defective is: stuffing box packing 18 mounting or dismounting between valve rod 5 middle parts and the valve gap 14 are inconvenient, and its compression stroke is too little, and how much not directly perceived the compression adjustment amount is, and structure is complicated.Four of defective is: be that valve rod 5 first halves are trapezoidal screw, the screw thread place drives vertical keyway, and this is worthless in Machine Design.It is discontinuous that keyway makes that screw thread disconnects, and is stuck easily.Five of defective is: valve rod travel is oversize during keying, can not fast opening and closing.In sum, existing routine techniques or patented technology all exist critical defect and deficiency, can not satisfy that offshore oil platform, boats and ships, naval vessels isoballast cabin advance, the specific (special) requirements of draining, therefore can not guarantee that it berths or navigation safety.
(3) summary of the invention
The purpose of this utility model just is autonomous innovation, develops and provide a kind of distinguished stopcock combination brake switch and proporting.The structural feature of stop valve and stopcock is combined together dexterously, have the repertoire of stop valve and stopcock, form double-sealing.On structural design, fully take into account the special environment condition in the seawater, guarantee reliable in function such as anti-jam, leakage proof, full discharging and do not lose efficacy.
Above-mentioned purpose is realized by following technical proposals:
