Description
Technical field
The utility model relates to a kind of cut-off device, and more particularly, it relates to a kind of Y type safety check.
Background technique
Safety check claims again check valve, one-way valve or check valve, its effect is to prevent the medium directional flow in pipeline and the function safety check of unlikely refluence belongs to self-acting valve class, be mainly used on the pipeline of medium one-way flow, only allow medium to flow to a direction, to try to avert accidents, safety check refers to and relies on medium itself to flow and automatic open and close flap, is used for preventing the valve that medium flows backwards, and claims again check valve, one-way valve, reflux valve and back pressure valve.Safety check belongs to a kind of automatic valve, and its Main Function is to prevent that medium from flowing backwards, preventing pump and drive motor reversion, and the releasing of vessel media.
At present, (Chinese patent that application number is 200820218908.X discloses a kind of valve flap suspension structure of swing check valve) on market, this model utility is between the flap of Swing check valve and rocking bar, to adopt " sphere and cylinder " structure; Flap and rocking bar contacting point are made as to spherical shape, with sphere, match with the cylindrical hole face of rocking bar, sphere need only meet the moving needs that coordinate with the cylindrical hole face matching gap of rocking bar." sphere and cylinder " structure makes to coordinate for moving and coordinate between flap and rocking bar, and the sphere of flap can be made space free and rotate in the cylindrical hole of rocking bar, can compensate the error that " sealing pair " produces because of processing and assembling, and shaft clearance is little; After assembling, can make the mutually absolute keeping parallelism of the processing Jiong Zhuan center of " sealing surface of seat " and the processing gyration center of " valve clack sealing surface ", valve " sealing pair " fits like a glove mutually.Although having, this safety check can compensate " sealing pair " because of the error of processing and assembling generation, shaft clearance is little, can allow preferably valve " sealing pair " mutually fit like a glove, but this valve exists some problems, the seal arrangement of the valve of this patent is to adopt single screw directly to connect, easily loosening in just long-term use, and when valve opening, easily make flap directly strike valve body, cause valve body impaired.
Model utility content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of fastening performance by force and can directly avoids flap directly to clash into the Y type safety check of valve body.
For achieving the above object, the utility model provides following technological scheme: a kind of Y type safety check, comprise valve body, seal arrangement, described seal arrangement comprises flap, hanging platform and rocking bar, described rocking bar one end is fixedly connected with flap, the rocking bar the other end is connected with hanging platform articulated manner, described hanging platform comprises support, block and link plate, support comprises the first support and the second support, the first support is parallel with the second support, the first support be fixed on link plate lower end vertical with the second bracket end, block one end is placed between the first support and the second support and is fixed under link plate, in described valve body, be provided with parallel raised line, link plate is hung on parallel raised line, link plate is fastenedly connected with parallel raised line, described link plate is provided with at least two screw fastenings with raised line and is connected.
By adopting technique scheme; adopt parallel raised line to be fixedly connected with link plate; no longer adopt single raised line to insert in the middle of support; this means of fixation is easily loosening, causes sealing not strong, and block is arranged on seal arrangement; avoided in the time of valve opening; flap is directly selected, to valve body, well to have protected valve body, has extended the working life of valve body.
The utility model is further set to: described screw is provided with trembleuse cup.
By adopting technique scheme, trembleuse cup is set, can further play antihunt action.
The utility model is further set to: on described flap, be provided with elasitic layer with block collision end.
By adopting technique scheme, when valve opening, can avoid flap directly to strike above block, by an elasitic layer is set, played the effect of buffering in the above, can well protect block and flap.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model embodiment's Y type safety check.
Fig. 2 is the inner local enlarged side view of the utility model embodiment's Y type safety check.
Reference character in figure: 1, valve body; 2, flap; 3, parallel raised line; 4, block; 5, link plate; 6, the first support; 7, the second support; 8, rocking bar.
Embodiment
Referring to figs. 1 through Fig. 2, the utility model embodiment is described further.
A kind of Y type safety check, comprise valve body 1, seal arrangement, described seal arrangement comprises flap 2, hanging platform and rocking bar 8, described rocking bar 8 one end are fixedly connected with flap 2, rocking bar 8 the other ends are connected with hanging platform articulated manner, described hanging platform comprises support, block 4 and link plate 5, support comprises the first support 6 and the second support 7, the first support 6 is parallel with the second support 7, the first support 6 be fixed on link plate 5 lower ends vertical with the second support 7 ends, block 4 one end are placed in the first support 6 and 7, the second support is fixed on link plate 5 times, in described valve body 1, be provided with parallel raised line 3, link plate 5 is hung on parallel raised line 3, link plate 5 is fastenedly connected with parallel raised line 3, described link plate 5 is provided with at least two screw fastenings with raised line and is connected.In valve body 1, there is a fluid through-hole, by flap 2 is sealed up to fluid through-hole, make safety check one-way flow, by flap 2 being fixed on to rocking bar 8 one end, rocking bar 8 the other end hinge-connection fixeds fix in the middle of the first support 6 and the second support 7, the first support 6 and the second support 7 are fixed on link plate 5, by coordinating link plate 5 to be fixed on the parallel projection on valve body 1, by two screws are at least set, can guarantee fully the fastening performance that hanging platform is installed, and link plate 5 lower ends between the first support 6 and the second support 7 are provided with a block 4, in the time of can preventing flap 2 unlatching, avoid directly clashing into valve body 1, well protected valve body 1.
Described screw is provided with trembleuse cup.When Y type safety check is opened closed constantly circulation, flap 2 needs continuous opening and closing, activity by flap 2 produces some vibrations, the screw that can affect on hanging platform connects, by be provided with trembleuse cup on screw, can fine and effectively play shockproof effect, better guarantee fixing stability.
On described flap 2, be provided with elasitic layer with block 4 collision ends.When Y type safety check is opened closed constantly circulation; flap 2 needs continuous opening and closing; flap 2 is opened and is made; do not seal with fluid through-hole; flap 2 withstands on block 4, by elasitic layer is set, avoids directly touching block 4 of flap 2; thereby well protected flap 2 and block 4, extended working life.
Because the utility model example has solved the fastening poor performance of valve and the direct problem of clashing into valve body 1 of flap 2, the working life of having improved valve.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, those skilled in the art carries out common variation and replaces should being included in protection domain of the present utility model within the scope of technical solutions of the utility model.
