Abstract
The utility model provides a split type push -pull valve. The current push -pull valve weight of main solution is big, with high costs, and the problem of inconvenient dismantlement maintenance. Its characterized in that: well clack box right side extends to the outside of right clack box, the flexbleJoint sets up the right side at well clack box, flange joint is passed through with well clack box in the flexbleJoint left side, the right side outer lane of flexbleJoint is equipped with the limiting plate to be connected through gag lever post and right clack box. Its advantage lies in the flexbleJoint setting outsidely at the valve, and more convenient the dismantlement is maintained, changes the flexbleJoint under the condition of convenient downriver not evacuation of equipment gas, the economic loss of greatly reduced operator, and simultaneously because the flexbleJoint setting is outside at the valve, relative left clack box and the interval between the right clack box also can reduce to make the weight of valve reduce, further reduced the cost of manufacture, improved market competitiveness of the product.
Description
Technical field
This utility model relates to a kind of push-pull valve, is specifically related to a kind of split type push-pull valve.
Background technology
Existing open gate valve, is mainly driven assembly, hoofing part assembly etc. to form by frame, left clack box, middle clack box, right clack box, valve plate, compensator, valve plate suspension assembly, valve plate positioning component (hook wheel, top wheel), synchronous clamping assembly, clamping.The switch of valve is realized with blind plate position by the through hole on conversion plate, and valve plate conversion need to carry out sequentially-operating in the case of corrugated expansion joint unclamps.
Together with frame is linked with left clack box, right clack box, for determining the overall installation length of valve, position is relatively fixed.Middle clack box uses welding manner to connect together by compensator with right clack box, and middle clack box can move left and right under the effect of driving means and clamping synchronizer.Valve plate is divided into blind hole and open-work, is realized the opening and closing of valve by the switching of blind hole and open-work.Valve plate is suspended on the track of clack box by hanging beam assembly, and the effect being taken turns and pushing up wheel by hook can realize moving left and right, and meanwhile, under the effect of travel driving unit, valve plate can also realize seesawing, it is achieved valve plate blind hole and the switching of open-work.Valve plate valve event order is: when the valve is open, first removed to the right sealing surface by driving clamping device by clamping synchronizer (synchronizer is made up of crank, pull bar, screw rod, nut etc.) band disorder of internal organs clack box, have on middle clack box and take turns equipped with hook, simultaneously equipped with top wheel on left clack box, when valve fully opens, under the effect of hook wheel and top wheel, valve plate is placed exactly in left clack box sealing surface and the centre position of middle clack box sealing surface, and valve body is kept completely separate with sealing surface of valve plate.Now can start travel driving unit makes valve plate carry out before and after's sliding along track, and the blind plate on valve plate is moved to pipeline location.Restart driving clamping device, valve plate is clamped completely, i.e. complete valve closing action.When valve is opened, the most first clamping device is fully opened, then valve plate open-work is moved to pipeline location, clamp valve plate the most again and complete opening operation.
The push-pull valve of this kind of structure is to use the most a wide range of push-pull valve structure up to now, in use, has the disadvantage in that the most flimsy position of valve is FlexbleJoint, and compensator once damages, then mean that whole deck valve door damages and lost efficacy.In process of production, this kind of valve is generally used on the import of gas tank, outlet conduit or on gas piping.Needing when changing this valve all to bleed off the gas of air accumulator and need just can carry out under damping down state, therefore, the damage of valve will bring huge economic loss to manufacturing enterprise.In order to change the compensator of damage in the case of not affecting production easily, become the enterprise's a kind of strong demand to split type push-pull valve.But in existing product, sector blind plate valve can conveniently realize Split type structure, but push-pull valve generally inside nominal diameter is the biggest, clamping point is all more than 6 o'clock, and compensator is positioned at the position, middle of clamping screw, if traditional structure is made split type, it is difficult to accomplish free dismounting, makes and split type there is no practical significance.If make split type can free detaching structure, needing minimizing clamping point quantity to 4 points, split type compensator just can be made can to take out from door side, 4 clamping structures can realize the split type of valve, but have the disadvantage that: one is that left and right clack box distance strengthens, and makes the weight of valve substantially strengthen；Two is that FlexbleJoint hits exactly at valve, and detachable maintaining is very inconvenient.Therefore, the push-pull valve used currently on the market is typically all overall structure.How conventional valves is carried out structure improvement and realize the split type of push-pull valve, become the important topic developing split type push-pull valve.
