Description
Technical field
The utility model relates to a kind of pressurized container outlet valve, and specifically finger can regulate the valve of exhaust velocity automatically according to container inner pressure size.
Background technique
High pressure steam sterilization is the means that food, biology, pharmaceuticals industry are commonly used, and after sterilizing completes, high-pressure sterilizing pot need to be controlled exhaust velocity when decompression exhaust.It is situation about often running into that filling or bagged material are carried out to high pressure steam sterilization, while just having started exhaust after sterilizing completes, because temperature and pressure in autoclave is all higher, if the too fast meeting of exhaust decompression causes filling material bulging distortion or the quick-fried bag of bagged material, and increase when pressure decreased needs exhaust aperture to a certain extent time, make low pressure exhaust speed to increase work efficiency.
Adopt manual control exhaust velocity, not only troublesome poeration, waste of manpower, and inaccuracy very, be difficult to obtain satisfied effect, thereby be starved of a kind of valve that can automatically regulate exhaust velocity, when when pressure is higher, less, the pressure of exhaust aperture is lower, exhaust aperture is larger, the in the situation that filling or bagged material being not impaired in autoclave, obtains ideal exhaust velocity faster.
Model utility content
The technical problems to be solved in the utility model overcomes the deficiencies in the prior art exactly, a kind of simple in structure, practical, outlet valve that can automatically regulate exhaust aperture is provided, when while making pressure higher, less, the pressure of exhaust aperture is lower, exhaust aperture is larger, in the situation that material is not impaired, obtain desirable exhaust velocity.
For overcoming the deficiencies in the prior art, the utility model is taked following technological scheme:
A kind of automatic adjusting outlet valve, comprise suction tude threaded coupling, valve gap, poppet shaft, outlet pipe threaded coupling, spring, hand-screw plug screw, lock nut, valve body, revolve hand, spool and plug screw, it is characterized in that: valve body lower end is suction tude threaded coupling, can be connected with autoclave relief opening, there is valve gap suction tude threaded coupling upper end, valve gap is connected with poppet shaft, spool axle sleeve has hand-screw plug screw, there is lock nut hand-screw plug screw upper end, between hand-screw plug screw and valve gap, there is spring, by regulating the position of lock nut, and turn hand-screw plug screw is to appropriate location adjustable springs tension force, pressure during with exhaust is determined the aperture (the downward aperture of valve gap is determined by spring force and the acting in conjunction of lower gas pressure) of valve gap jointly, valve body is provided with outlet pipe threaded coupling, is convenient to be connected with exhaust duct, one side of suction tude threaded coupling has spool, and valve core upper sleeve has plug screw and revolves hand, and plug screw external sealing plug and valve seat coordinate, and internal sealing plug and spool coordinate, turn revolve hand can regulating spool and valve body between annular space, make to meet the requirements by the exhaust velocity of annular space.
Described spool is cone structure by suction tude one side, is convenient to finely tune the annular space between spool and valve body.
The utility model is to utilize just to start exhaust pressure when larger, valve gap holddown spring, valve gap is closed completely, exhaust velocity reduces, now pressurized gas can only be discharged along path along the annular space between spool and valve body, hand is revolved in now turn still can regulate exhaust velocity, and exhaust velocity when valve gap is closed meets the requirements; When pressure diminishes, spring is elongated, and valve gap aperture is increased, and exhaust velocity is accelerated.
Because spring ratio and the length of spring is all selectable, thereby the utility model device can be realized and automatically regulate exhaust according to pressure size, when when pressure is higher, less, the pressure of exhaust aperture is lower, exhaust aperture is larger, the in the situation that in autoclave, filling or bagged material being not impaired, obtain ideal exhaust velocity faster, the utility model device is also convenient to regulate and is used, and can reliably reach predetermined exhaust mode, and application prospect is very wide.

In figure, each label represents:
1, suction tude threaded coupling; 2, valve gap; 3, poppet shaft; 4, outlet pipe threaded coupling; 5, spring; 6, hand-screw plug screw; 7, lock nut; 8, valve body; 9, revolve hand; 10, spool; 11, plug screw.
Embodiment
Now by reference to the accompanying drawings, the utility model is further illustrated.
As Fig. 1, shown in Fig. 2 and Fig. 3, automatically regulate outlet valve, comprise suction tude threaded coupling 1, valve gap 2, poppet shaft 3, outlet pipe threaded coupling 4, spring 5, hand-screw plug screw 6, lock nut 7, valve body 8, revolve hand 9, spool 10 and plug screw 11, wherein valve body 8 lower ends are suction tude threaded coupling 1, can be connected with autoclave relief opening, there is valve gap 2 suction tude threaded coupling 1 upper end, valve gap 2 is connected with poppet shaft 3, poppet shaft 3 covers have hand-screw plug screw 6, there is lock nut hand-screw plug screw 6 upper ends, between hand-screw plug screw 6 and valve gap 2, there is spring 5, by regulating the position of lock nut 7, and turn hand-screw plug screw 6 is to appropriate location adjustable springs 5 tension forces, pressure during with exhaust is determined the aperture of valve gap 2 jointly, valve body 8 is provided with outlet pipe threaded coupling 4, is convenient to be connected with exhaust duct, one side of suction tude threaded coupling 1 has spool 10, on spool 10, cover has plug screw 11 and revolves hand 9, and plug screw 11 external sealing plugs and valve seat coordinate, and internal sealing plug and spool 10 coordinate, turn revolve hand 9 can regulating spool 10 and valve body 8 between annular space, make to meet the requirements by the exhaust velocity of annular space.
Described spool 10 is cone structure by suction tude one side, is convenient to finely tune the annular space between spool 10 and valve body 8.
During initial stage exhaust, autoclave body internal pressure is larger, valve gap 2 is pressed on valve seat airtight by high pressure steam, the aperture that makes valve gap is zero (as shown in Figure 1), now pressurized gas can only be discharged (as shown by arrows) along path by adjustable ring gap between spool 10 and valve body, hand 9 is revolved in turn can regulate exhaust velocity, has both guaranteed exhaust velocity faster, does not make again the material in pot body impaired.
When exhaust pressure progressively declines, valve gap 2 can open certain aperture (as shown in Figure 2) with valve seat under spring action, and air displacement increases, and exhaust velocity is accelerated.
When pressure further reduces, spring can make valve gap 2 be opened to full-gear (as shown in Figure 3), low pressure exhaust speed is increased greatly, to increase work efficiency.
The position of modulating valve mandrel 3 upper end locking nuts 7, and turn hand-screw plug screw 6 adjustable springs tension forces, reach the object that regulates valve gap 2 apertures and exhaust velocity.
