Description

A kind of high leakproofness multi-clack control valve

Technical field

The utility model is related to a kind of multi-clack control valve more particularly to a kind of high leakproofness multi-clack control valves.

Background technology

Multi-clack control valve is one kind of valve, has run-in index, opposite opened and light-duty opposite opened by tectonic type point；By close Closing requirement point has plain edition and hermetic type；There are power type, air-driven type and type hand by manner of execution point.

But in existing hermetic type multi-clack control valve technology, since valve block quantity is produced on two panels or more, between valve block Sealing performance weaken, even if valve block close, air still can be from the effusion up and down of valve block, and poor sealing, overall effect is not It is good.Accordingly, the utility model proposes a kind of high leakproofness multi-clack control valves.

Utility model content

The purpose of the utility model is to overcome above-mentioned deficiencies in the prior art, provide a kind of leafy adjusting of high leakproofness Valve, which has the characteristics that between valve block and favorable sealing property between valve block and valve body.

In order to solve the above technical problems, what the purpose of this utility model was realized in：One involved by the utility model Kind high leakproofness multi-clack control valve, including valve body, the valve body is interior to be equipped with upper valve block and lower disc, and upper valve on piece is equipped with rotation company The upper shaft being connected on the body wall, lower disc is equipped with the lower rotary shaft being rotatably connected on the body wall, described Upper shaft one end is connected with turns shelves one outside valve body, and lower rotary shaft one end is connected with turns shelves two outside valve body, described turn Shelves one and turn to be equipped with connecting rod between shelves two, connecting rod one end is hinged with described turn of shelves one, and the other end is hinged with described turn of shelves two, described Turn to be additionally provided with handler on shelves one, the lower edges of the upper valve block and lower disc glue respectively is equipped with upper strip and under strip, institute It states above upper valve piece, be equipped with the crosspiece affixed with valve body below lower disc；The upper valve block and lower disc both sides are equipped with patch The fluff strip being located on valve interior wall.

As further program of the utility model：A lock being hinged on valve outer wall is equipped with above the handler Hook.

As further program of the utility model：The valve body has mounting hole.

The utility model has the beneficial effects that：High leakproofness multi-clack control valve involved by the utility model, passes through valve block Lower edges respectively glue set adhesive tape so that between valve block and valve block be closed when, due to adhesive tape contact so that air cannot be from valve It is passed through between piece, increases the leakproofness between valve block and valve block；Pass through the setting of crosspiece so that the madial wall up and down of valve block and valve body Between do not stay gap, play the role of reinforce sealing；Fluff strip is set by valve block both sides so that in the left and right of valve block and valve body Gap between side wall reduces, and since valve block needs to rotate, necessarily there are certain interval between the madial wall of left and right, fluff strip is added, So that in the case of not influencing valve block rotation, reduces flowing through for air, further enhance leakproofness；By adding for latch hook, use Handler under hook lock valve block closed state prevents air velocity big and blows valve block open, and allomeric function is perfect, highly practical.

Description of the drawings

Fig. 1 is the structural schematic diagram of the utility model.

Specific implementation mode

The utility model is further illustrated with preferred embodiment below in conjunction with the accompanying drawings.

As shown in Figure 1, a kind of high leakproofness multi-clack control valve involved by the present embodiment, including valve body 1, the valve body 1 Interior to be equipped with upper valve block 2 and lower disc 3, upper valve block 2 is equipped with the upper shaft 4 being rotatably connected on 1 side wall of the valve body, lower disc 3 are equipped with the lower rotary shaft 5 being rotatably connected on 1 side wall of the valve body, and upper shaft 4 and lower rotary shaft 5 control valve block 2 under respectively The rotation of valve block 3, described 4 one end of upper shaft is connected with turns shelves 1 outside valve body 1, and 5 one end of lower rotary shaft is connected with set on valve Turning shelves 27 outside body 1, described turn of shelves 1 and turns to be equipped with connecting rod 8 between shelves 27,8 one end of connecting rod is hinged with described turn of shelves 1, The other end is hinged with described turn of shelves 27, is additionally provided with handler 9 on described turn of shelves 1, the upper valve block 2 and lower disc 3 up and down Edge glues respectively is equipped with upper strip 10 and under strip 11, when between upper valve block 2 and lower disc 3 in closure, due to 10 He of upper strip Under strip 11 contacts so that air cannot pass through between upper valve block 2 and lower disc 3, increase between valve block 2 and lower disc 3 Leakproofness；2 top of the upper valve block, 3 lower section of lower disc are equipped with the crosspiece 12 affixed with valve body 1 so that valve block and valve body 1 Gap is not stayed between upper and lower madial wall, plays the role of reinforcing sealing；The upper valve block 2 and 3 both sides of lower disc are equipped with and are sticked Fluff strip 13 on 1 inner wall of valve body so that the gap between valve block and the left and right madial wall of valve body 1 reduces, since valve block need to turn Dynamic, necessarily there are certain interval between the madial wall of left and right, fluff strip 13 is added so that in the case of not influencing valve block rotation, Reduce flowing through for air, further enhances leakproofness.

Further, the top of the handler 9 is equipped with a latch hook 14 being hinged on 1 outer wall of valve body, by handler 9 to Upper turn turns shelves 1 and rotates counterclockwise, connected by connecting rod 8 so that turns 27 driven motions clockwise of shelves, valve block 2 in closure With lower disc 3, at this point, handler 9 is located at 14 lower section of latch hook, rotation latch hook 14 lives 9 hook lock of handler, completes handler 9 Locking prevents air velocity big and blows valve block 2 and lower disc 3 open, improves the leakproofness of valve body 1.

Further, the valve body 1 has mounting hole 15, installs valve body 1 convenient for passing through the fasteners such as screw or bolt.

The utility model is glued respectively by the lower edges of valve block sets adhesive tape so that between valve block and valve block when being closed, by It is contacted in adhesive tape so that air cannot be passed through between valve block, increase the leakproofness between valve block and valve block；Pass through setting for crosspiece It sets so that do not stay gap between valve block and the madial wall up and down of valve body, play the role of reinforcing sealing；It is arranged by valve block both sides Fluff strip so that the gap between valve block and the left and right madial wall of valve body reduces, must between the madial wall of left and right since valve block needs to rotate So there are certain interval, fluff strip is added so that in the case of not influencing valve block rotation, reduces flowing through for air, further Enhance leakproofness；It prevents air velocity big for the handler under hook lock valve block closed state by adding for latch hook and blows open Valve block, allomeric function is perfect, highly practical.
