When bleeding with pump bowl, flap valve is opened because of being subjected to suction, and the air in the vacuum capsule is through the spool bore sucking-off, and when stopping to bleed, suction is removed, and flap valve is closed rapidly because of restoring force own and vacuum capsule inside and outside differential pressure, and outside air can't return the vacuum capsule.So after the suction for several times, air is fewer and feweri in the vacuum capsule, and vacuum is more and more higher, finally makes the interior loose packing material originally of capsule be compressed into the hard plate.With finger extruding spool, make flap valve dislocation or perk during aerofluxus, spool bore is opened, and outside air enters rapidly in the vacuum capsule because of pressure reduction, and product returns to resting state.
This shows that flap valve is the critical component of check valve.Studies show that: rubber material, hardness and flap valve excision forming technology are the key factors of decision check valve performance.
Be not both with another of external like product, check valve of the present utility model adopts embedded type that design is installed, and promptly removes the one-way valve cover and exposes, and remainder is all imbedded in the vacuum capsule.This mounting means is not only installed firmly, makes outward appearance succinct, and can avoid check valve and extraneous foreign body extension to climb and damage.
Special single-way valve arrangement novelty of the present utility model, dependable performance.Show the activity of check valve flap valve freely, close tightly, gas does not take place to vacuum capsule suck-back phenomenon; Aerofluxus is unobstructed rapidly, can return to original state at 15 seconds from vacuum state with interior product.
5. the system of the packing material in the special this utility model of packing material processing technique adopts polystyrene plastics to process through newly-designed foam process.The density of expanded beads is critical index, crosses when low when density, and grain structure is loose, and compression resistance is poor, and the plate quality that forms under vacuum state is soft, and easily compression can't be to fracture limbs fixed support effectively.Standard-required of the present utility model: the proportion of packing material should be controlled at 0.08～0.12g/cm
3Scope; Particle diameter is in 2～5mm scope, and individual particle is applied the dead load of 4.9N, and the compress variation of diameter is not more than 10%.For reaching standard-required, the foam process of institute's employing polystyrene plastics is by the adjusting to blowing temperature, pressure, speed, and the control blowing ratio becomes granule foaming stiff particle artificially, boils " half-cooked rice ", has satisfied requirement of the present utility model.
Because expanded beads has certain rigidity, the coefficient of friction on surface is little than soft particle, causes granule easy play in the vacuum capsule, and inconvenience is sprawled when the parcel limbs, is easy to gather to lower, makes troubles to use.For addressing this problem, must improve the processing of adhesive force to packing material.Method is to add certain amount of neutral, high viscosity oiliness liquid in packing material, makes its gathering agglomerating, has reduced flowability, has reached its intended purposes.
Adopt during use vacuum pumping method with in the vacuum capsule originally loose particles of packing material to be compressed into the hard plate that matches with limbs fast, with fixing and support the principle of fracture site, send after the safety for the fracture wounded and give security.
The utlity model has good air-tightness, guaranteed the formation of vacuum and keep.Packing material light weight and voltage endurance satisfies fixed hardness
