Embodiment
With reference to Fig. 1, Fig. 2, Fig. 3,, be applicable to Roots blower supply air system and multipole centrifugal blower supply air system for adopting a kind of self-powered air relief device of the present invention.Wherein, diaphragm frame 3 circumferentially evenly offers a plurality of flank exhaust ports 6, and pedestal 4 has air channel, large-sized 5 center.One end of diaphragm frame 3 is connected to the outlet end of pedestal 4, passes through screw; The other end of diaphragm frame 3 is connected by the oral area of bolt with top cover 1, and fixing diaphragm 2 between the two realizes that top cover 1, diaphragm 2, diaphragm frame 3 are connected with the coaxial superimposed of pedestal 4.
At diaphragm 2 centers, center guide pin bushing 9 cover that is fixed 10 is fastened on the diaphragm 2.Top cover 1 center is connected with air pipe 8, and an end of air pipe 8 stretches into air channel, center 5, and the other end of air pipe 8 stretches out top cover 1 back and connects selector valve 13, and an outlet of selector valve 13 is as relief opening, and another outlet is communicated with chamber 7 by pipeline.Center guide pin bushing 9 slides and is applied on air pipe 8 external diameters, is provided with three seals circle 11 between center guide pin bushing 9 and the air pipe 8, guarantees the sealing of cavity 7; Air pipe 8 adopts Stainless Steel Tube, guarantees the flexible slip of center guide pin bushing 9 on air pipe 8.
Throttling bolt 12 with throttle orifice 16 is set in air pipe 8, concrete structure as shown in Figure 4, throttling bolt 12 is connected by the internal thread of outside thread with air pipe 8, throttle orifice 16 is offered at throttling bolt 12 centers.Have the throttling bolt 12 of the throttle orifice 16 in different apertures by replacing, can conveniently regulate the opening and closing time of diaphragm 2.
With reference to Fig. 5, diaphragm 2 is for being cast with the sheet rubber of fiber, and its toughness is very strong, can prevent to tear, and greatly reduce the thickness of diaphragm, and it is moved in stroke flexibly; The central layer interlayer 15 of diaphragm 2 center casting metals, central layer interlayer 15 areas of metal are convenient to the fixing of center guide pin bushing 9 greater than air channel, center 5 sectional areas, make diaphragm 2 beat can not occur when motion; The periphery of diaphragm 2 has the O type location seal ring 14 of the one of being cast for, and reaches the effect of self poisoning on the one hand, on the other hand top cover and being connected of diaphragm frame is sealed.
When selector valve 13 is inflated in cavity 7, because diaphragm 2 areas are greater than air channel, center 5 sectional areas, can make diaphragm 2 produce downward making a concerted effort, diaphragm 2 moves to air channel, center 5, progressively the closing center air channel 5, and especially in high-pressure high-temperature environment, the impacting force of the high more generation of the working pressure of gas is big more, can guarantee fully not have and leak, realize selfsealings.When selector valve 13 turned to relief opening to be communicated with environment, diaphragm 2 moved away from air channel, center 5 under the gas pressure effect in air channel, center 5, and air channel, center 5 is communicated with the flank exhaust port 6 that is opened in diaphragm frame 3, unloads.
Self-powered air relief device of the present invention, have good airproof performance, compact structure, action accurately, control advantages such as convenience, working stability, energy saving; Especially in high-pressure high-temperature environment, because it belongs to selfsealings, the high more impacting force that it produces because of the top and bottom product moment of pressure is big more, can guarantee fully not have to leak; And, according to the size of unloading flow, can in parallelly use.
Although below in conjunction with the accompanying drawings embodiment of the present invention are described, invention is not limited to above-mentioned specific embodiments, and above-mentioned specific embodiments only is schematic, guiding, rather than restrictive.Those of ordinary skill in the art under the situation that does not break away from the scope that claim of the present invention protects, can also make a variety of forms under the enlightenment of this specification, these all belong to the row of the present invention's protection.
