Abstract
The utility model discloses a vacuum flap valve, which comprises a vacuum cavity, a turnover shaft, a locking plate, a pressing arm and a connection seat, and is characterized in that: the turnover shaft is fixedly connected to a swinging cylinder outside the vacuum cavity; one end of the pressing arm is fixedly connected to the turnover shaft, and the other end of the pressing arm is hinged with the locking plate through the connection seat; the end of the pressing arm connected with the locking plate is provided with a through hole; a spring is arranged in the through hole; the upper end of the spring is fixed on the locking plate, and the lower end of the spring is fixedly connected to a spring pressing member; and the position of the locking plate is adjusted by the vacuum turnover plate through the spring pressing member, so that the sealing surfaces of the locking plate and the vacuum cavity are attached to each other in parallel; and thus, the problem of poor sealing property of the vacuum flap valve is solved, and the vacuum flap valve has a simple structure and is easy to implement.
Description
Technical field
The utility model relates to a kind of gas valve, relates in particular to a kind of vacuum flap valve.
Background technology
The vacuum continuous coating production line generally is made up of the module of a plurality of difference in functionalitys; Be line example formula and be bolted together, plated substrate to get into, accomplish coating process through whole coating film production line from an end; From the other end slice; Satisfy vacuum plating and normally move needs and satisfy the different vacuum tightnesss between disparate modules, form from atmosphere → coating process pressure → atmospheric pressure gradient, the vacuum flap valve is a core component of realizing above-mentioned functions.
At present; Flap valve on the market mainly contains component such as trip shaft, bulb nut, pressure strip, jam plate, sealing-ring, vacuum cavity and forms; Trip shaft is fixed on the outer oscillating cylinder of cavity; Pressure strip is welded on the trip shaft, pressure strip is connected together with jam plate with double-screw bolt through the bulb nut; Yet there is following problem in this kind flap valve:
1, vacuum-sealing is unreliable, and gas-blowing phenomenon is arranged, and when leaning on flap valve sealing adjacent block pressure change, this module pressure change is also very big.
2, repeat poor sealing, bad during the sealing reliability fashion.
3, between flap valve sealing plate and the cavity trim, near the joint place, two faces are not parallel, cause the stranding cushion rubber, make sealing property descend the cushion rubber rapid wear.
The utility model content
The purpose of the utility model is to provide a kind of vacuum leakproofness good to the problems referred to above, repeats the high and vacuum flap valve simple in structure of sealing reliability.
The purpose of the utility model is to realize through following technical scheme:
A kind of vacuum flap valve comprises vacuum cavity, trip shaft, jam plate, pressure arm and Connection Block, and said trip shaft is fixedly connected on the outer oscillating cylinder of vacuum cavity; One end of said pressure arm is fixedly connected on the trip shaft; Its other end is hinged through Connection Block and jam plate, and the end that said pressure wall is connected with jam plate has through hole, is provided with spring in the said through hole; The upper end of said spring is fixed on the jam plate, and its lower end is fixedly connected with spring application spare.
Special, said jam plate periphery is provided with water-cooled tube, is fixedly connected with the water-cooled joint on the said jam plate, and said water-cooled joint links to each other with vacuum cavity.
Preferably, said jam plate and trip shaft are processed by duraluminum.
Preferably, the contact surface of said jam plate and vacuum cavity is provided with sealing-ring.
The beneficial effect of the utility model does; Above-mentioned vacuum flap valve is connected jam plate through adopting articulated manner with pressure arm, making has certain angle of revolution between jam plate and the pressure arm, adjust the jam plate position through spring application spare; Make the parallel applying of trim of jam plate and vacuum cavity; Strengthened the stopping property of vacuum flap valve, and simple in structure, be easy to realize.
Description of drawings
According to accompanying drawing and embodiment the utility model is done further explain below.
Fig. 1 is the structural representation of the utility model vacuum flap valve;
Fig. 2 is a vacuum flap valve shown in Figure 1 sectional view at the D-D place.
Among the figure:
1, pressure arm; 2, trip shaft; 3, Connection Block; 4, water-cooled joint; 5, jam plate; 6, oscillating cylinder; 7, spring; 8, sealing-ring; 9, vacuum cavity; 10, spring application spare.
Embodiment
Please with reference to Fig. 1 and shown in Figure 2, in present embodiment, a kind of vacuum flap valve; Comprise vacuum cavity 9, trip shaft 2, jam plate 5, pressure arm 1 and Connection Block 3; Said trip shaft 2 is fixedly connected on the oscillating cylinder 6 outside the vacuum cavity 9, and an end of said pressure arm 1 is fixedly connected on the trip shaft 2, and its other end is hinged through Connection Block 3 and jam plate 5; The end that said pressure wall 1 is connected with jam plate 5 has through hole; Be provided with spring 7 in the said through hole, the upper end of said spring 7 is fixed on the jam plate 5, and its lower end is fixedly connected with spring application spare 10.
Special; Said jam plate 5 peripheries are provided with water-cooled tube; Be fixedly connected with water-cooled joint 4 on the said jam plate; Said water-cooled joint 4 links to each other with vacuum cavity 9, makes the environment for use of the utility model vacuum flap valve increase to 400 degrees centigrade from room temperature, has satisfied the demand of various high temperature coating process.
Preferably, said jam plate 5 and trip shaft 2 are processed by duraluminum, allow to produce micro-deformation down in the effect of pressing wall, though exist process, assembling error, the trim of jam plate is fitted tightly.
Preferably, said jam plate 5 is provided with sealing-ring 8 with the contact surface of vacuum cavity 9.
The principle of work of the utility model does; Oscillating cylinder 6 gains impetus through pressurized air and rotates; Make trip shaft 2 rotations, trip shaft 2 drives press wall 1 and hinged with it jam plate 5 to rotate, jam plate 5 has certain angle of revolution with pressure wall 1; Through the position of spring application spare 10 adjustment jam plates 5, make on the parallel trim that fits in vacuum cavity 9 of jam plate 5.
Above-mentioned vacuum flap valve is not only simple in structure, is easy to realization, and good airproof performance, can satisfy the demand of various high temperature coating process.
