Description
Technical field
The utility model relates to dust suction dust arrester accessory, is a kind of suction port opening valve of multipoint positioning dust exhaust apparatus specifically.
Background technology
In view of industrial dust collector on the market only provides a dust suction air port usually, like this using in needs dedusting on a large scale or the multipoint positioning dedusting under efficient shows slightly, so our company answers the client need design and develop and produce a series of auxiliary products.
In the work of the former dedusting of keeping a public place clean, our method of use is a dust catcher usually, joins a cover Great Wall Software pipe racks suction nozzle, and vacuum sweeper walks where to wash dust suction mode where.Following limitation appears in this sample loading mode easily.
1〉if moving, the Small-sized suction cleaner main frame goes back Shangfang just, very inconvenient if large-scale dust catcher moves, and time-consuming taking a lot of work.
2〉can only there be a dust suction position to carry out dust suction, inefficiency in the same time and place.
3〉the long traction of the flexible pipe wrinkling damage of discounting easily.
In order to address the above problem, our company has designed the scheme of multistation dust suction, do total air channel with a hardwired pipeline, design several valves and do the dust suction air port, realize large-scale mobile dust suction by on the air port, patching hose, comparatively Ben Chong main frame itself can fixedly mount, and is convenient to safeguard.
Needing this moment to solve is to need on the dust suction air port conveniently to seal and to open use, and can both start the opening valve that dust catcher does not influence other air ports again on each air port.
Summary of the invention
The purpose of this utility model provides a kind of suction port opening valve of multipoint positioning dust exhaust apparatus, can use by supporting multipoint positioning dust catcher, conveniently seals and open each air port separately, the use of being convenient to open the dust catcher running simultaneously and not influencing other air ports.
The suction port opening valve of described multipoint positioning dust exhaust apparatus, it is characterized in that: comprise valve body, valve gap, limit switch, the valve gap that is buckled in the valve body front opening is connected on the towing plate by screw rod, and an end of described towing plate is fixedly hinged, and limit switch is fixedly mounted on towing plate in one's power in the scope.
The hinged end of described towing plate is equipped with locating pin, and holddown spring is housed on the locating pin.
Described holddown spring is to make valve gap compress the torsion spring of valve body.
Described valve gap is provided with the external seal lid and is located at the interior seal cover of its front end.
The interior seal cover that described external seal covered and be located at its front end is an one, and the center is installed with the screw rod that is fixed on the towing plate, is with spacing and adjusts block on the screw rod in the interior seal cover outside.It is the spacing that is used for adjusting between valve gap and the towing plate that spacing is adjusted block.
The front end of described limit switch is a switch control contact, and switch control contact was pulled the position that plate is pressed into when limit switch was positioned to cover tight valve gap.The position of satisfying this condition is a lot, for example when the tight valve gap of lid, control the contact lower limb along towing plate lower edge alignment switch, on this line, all satisfy condition, can also be at the fixed-site switch control block of towing plate to inductive switch control contact, limit switch can move after an aforesaid line position is suitable, utilizes the switch control block adjustment to be pressed into the gap.
When the seal cover of the utility model opening valve closed, valve gap was buckled on the suction port air door by the Prssure lock of locking spring, used the gap because of connection leaves locking with bolt, so spring tension is strained valve gap automatically, eliminated the gap, reached the effect of thorough sealing.
The present invention has following advantage:
1〉simple in structure, be convenient to produce;
2〉easy to use, the closed control automatically of the unlatching of dust catcher;
3〉be convenient to maintenance and repair, it is convenient to change;
4〉reequip easily, generally be applicable to the relevant devices in various working condition dust suctions and air channel;
5〉attractive and durable.
Description of drawings
Fig. 1 is the utility model opening valve closed condition structural representation,
Fig. 2 is the utility model opening valve open mode structural representation.
Among the figure: the 1-valve body, the 2-screw rod, the 3-spacing is adjusted block, seal cover in the 4-, 5-towing plate, 6-external seal lid, 7-holddown spring, 8-locating pin, 9-limit switch, 10-switch control contact, 11-exhaust tube, 12-sweep-up pipe connector, 13-switch control block.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified: the suction port opening valve of multipoint positioning dust exhaust apparatus as shown in Fig. 1,2, comprise valve body 1, valve gap, limit switch 9, the valve gap that is buckled in valve body 1 front opening is connected on the towing plate 5 by screw rod 2, one end of described towing plate 5 is fixedly hinged, and limit switch 9 is fixedly mounted on towing plate 5 in one's power in the scope.As primary condition, the position of limit switch 9 is done concrete introduction in the back with this.
Described holddown spring 7 is to make valve gap compress the torsion spring of valve body.The effect of torsion spring that is to say the driving fit that guarantees valve gap when the valve bonnet seal state.
Described valve gap is provided with external seal lid 6 and is located at the interior seal cover 4 of its front end.So that the effect of enhanced leaktightness.
Described external seal lid 6 is one with the interior seal cover 4 of being located at its front end, and the center is installed with the screw rod 2 that is fixed on the towing plate 5, is with spacing and adjusts block 3 on the screw rod 2 in interior seal cover 4 outsides.
The front end of described limit switch 9 is switch control contacts 10, and switch control contact 10 was pulled the position that plate 5 is pressed into when limit switch 9 was positioned to cover tight valve gap.The position of satisfying this condition is a lot, for example when the tight valve gap of lid, control contact 10 lower limbs along towing plate 5 lower edges alignment switch, on this line, all satisfy condition, can also be at switch control block 13 of fixed-site of 5 pairs of inductive switch control of towing plate contact 10, limit switch 9 can move after an aforesaid line position is suitable, utilizes the thickness adjustment of switch control block 13 to be pressed into the gap.
The tail end sweep-up pipe connector 12 of valve body 1 is connected with the air channel.In practical operation, when drawing back towing plate 5, limit switch is promptly opened automatically, sees the opening valve open mode structural representation of Fig. 2, sends signal notice main frame immediately, will start the dust catcher running iff having only this switch to be in closure state.Just can connect external hose enforcement dust suction after valve gap draws back has operated.Behind the dust suction EO, break away from flexible pipe, the towing plate of directly slippaging has just covered valve gap, and Fig. 1 is an opening valve closed condition structural representation, has disconnected limit switch simultaneously, promptly notifies the sealing state in this air port of main frame this moment.
