Embodiment
Embodiment: as shown in figs. 1-12, the invention provides the specific embodiment that a kind of medical air moves band saw gas control equipment, it comprises: housing 10, be positioned at housing 10 side joint 20, be arranged on housing 10 and one end dock with joint 20 valve body 30, be arranged on housing 10 and the pneumatic motor 40 docked with the other end of valve body 30 and control valve body 30 work and prevent the snap close piece of misoperation.
Joint 20 comprises plenum duct 22 and is centered around the return gas channel 24 outside plenum duct 22.
Valve body 30 comprises gas-entered passageway 32, the valve road 34 be connected with gas-entered passageway 32, be arranged on the valve collar 31 in valve road 34, be arranged on the outlet passageway 36 outside valve road 34, by the active tunnel 38 of carrying out between valve road 34 and outlet passageway 36 connecting, be arranged on the plunger 33 in active tunnel 38 movably, be arranged on plunger 33 end and the reciprocal spring 35 of spring-back force is provided, to be arranged between valve road 34 and valve collar 31 and to be the valve sealing ring 37 of static seal, and to be arranged between plunger 33 and active tunnel 38 and to be the plunger sealing washer 39 of motive sealing.Outlet passageway 36 comprise be connected with active tunnel 38 arcuate segment 360, be formed on arcuate segment 360 end and the breach 362 be connected with pneumatic motor 40.
Snap close piece comprise can pivot control arm 50, fixed base 51 below control arm 50, can pivot and the action plate 52 above control arm 50, the pair of rotary shafts 54 be arranged on fixed base 51, to be arranged in fixed base 51 and spring 56 between running shaft 54 and through fixed base 51 and the spiral shell 58 fixing with valve body 30.Wherein control arm 50 can horizontal reciprocating movement relative to fixed base 51, and have can with the U-shaped end 500 of plunger 33 tip contact, fixed base 51 is provided with the fixing bore 510 allowing plunger 33 to pass.U-shaped end 500 comprises separate space 502 between a pair U-shaped portion and interval U-shaped portion.Action plate 52 has the accepting groove 520 of collecting control arm 50, control arm 50 Following effect plate 52 is rotated around running shaft 54, control arm 50 and running shaft 54 contact segment have horizontal activity space simultaneously, make control arm 50 can relativity plate 52 horizontal reciprocating movement, realize the U-shaped end 500 of control arm 50 and the conversion of plunger 33 tip contact mode, reach control object.
During work, gas is entered in the gas-entered passageway 32 of valve body 30 by the plenum duct 22 of joint 20, and enters subsequently in valve road 34.Under normal state, because plunger sealing washer 39 leans against in active tunnel 38, so gas is in sealing state under the effect of the spring force of reciprocal spring 35.When pressing action plate 52 generation with hand and pivoting, drive the coaxial rotating of control arm 50 thus and make the U-shaped end 500 i.e. bottom surface of U-shaped arm downwardly against contact plunger 33 top, realize moving downward of plunger 33, Fig. 1 is the state after compressing, plunger 33 downwards and oppress reciprocal spring 35, thus drive the plunger sealing washer 39 be set on plunger 33 to move downward, depart from sealing thus, gas can enter in the active tunnel 38 of valve collar 31 by the gap between plunger 33 and active tunnel 38, and enter in outlet passageway 36 subsequently, gas first enters in breach 362 through arcuate segment 360 again, and breach 362 be offer in the side of valve body 30 and be connected with aeromotor 40, thus realize gas and enter aeromotor 40.When unclamping hand, plunger 33 will make plunger sealing washer 39 reliably be enclosed in active tunnel 38 under the effect of the spring force of reciprocal spring 35 and pressurized gas, reliably realize motive sealing, and the valve sealing ring 37 be arranged between valve road 34 and valve collar 31, because valve road 34 and valve collar 31 are all static parts, realize static seal thus.
When preventing misoperation, when not in use or in transportation process, control arm 50 is pulled to the second place of Figure 10 by the primary importance level of Fig. 9, the top of plunger 33 loses oppresses and enters in chamber, interval 502, and the height of a separate space 502 is greater than the top that plunger 33 exposes, now pressing action plate 52 again can not drive control arm 50 to move downward, thus avoid destroying gas seal to moving to lower compression of plunger 33, also finally prevent gas from entering pneumatic motor to realize the work of pneumatic motor.
Present invention achieves the misoperation preventing operator, easy to operate, good airproof performance, air tight.
Certain above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalent transformations of doing according to the Spirit Essence of main technical schemes of the present invention or modification, all should be encompassed within protection scope of the present invention.
