Abstract
The utility model discloses a non-repeated bottle-filling valve for industrial use, which comprises a valve rod, a valve core, and a guide rod which is connected with the valve core into an integral body. The guide rod is inserted into a guide hole which is arranged on the lower part of the valve rod. The guide rod and the valve rod which is matched with the guide rod are provided with pin holes which are provided with connector pins inside. Besides, the guide hole is provided with a spring. The utility model overcomes the defects in the prior art that a valve body has a complicated inner structure, has a high demand in machining accuracy and has a large difficulty in assembly; a valve core can easily fall off and influence a filling effect in filling time.
Description
The utility model belongs to a kind of valve, belongs to a kind of and the supporting use of refrigerant packing steel cylinder especially as the disposable industrial non-once-used filling cylinder valve that fills refrigerant.
Because factor of safety, as the steel cylinder of packing refrigerant, country expressly provides that its cylinder valve all need adopt non-once-used filling cylinder valve, to stop once-used filling at present.Before the utility model is made, polytype cylinder valve is arranged both at home and abroad.Relatively being typically China Patent No. is 98250798.4 cylinder valves of being introduced, and its structure comprises valve rod, spool and be linked to be whole guide rod with spool that guide rod inserts in the pilot hole of stem lower portion.Before charging refrigerant, valve rod is backspin not, makes spool be positioned at body cavity top; Charge and finish, the backspin valve rod makes it spool roof fall body cavity bottom withstand on the valve body sealing surface, reaches and closes purpose.During use, unscrew valve rod, at this moment, the bottle pressure is washed spool open makes refrigerant discharge from valve nozzle.But the shortcoming of this valve is: the requirement on machining accuracy height, and the assembling difficulty is big, and spool comes off easily and influences and charge when charging.
The purpose of this utility model provides the novel industrial non-once-used filling cylinder valve of a kind of structure.It is good that this cylinder valve not only has the once-used filling of preventing performance, and requirement on machining accuracy low, easy to assembly, charge Shi Buhui and spool occurs and come off and influence the phenomenon that charges.
The purpose of this utility model reaches by following technical proposals:
The utility model is a kind of industrial non-once-used filling cylinder valve, its structure comprises valve rod, spool and is linked to be whole guide rod with spool, guide rod inserts in the pilot hole of stem lower portion, its structure outline is: have pin-and-hole on guide rod and the valve rod that is complementary with it thereof, be provided with latch in the pin-and-hole.
The utility model also is provided with spring in the specific implementation in the pilot hole.
Compare the utility model with the known technology product owing on guide rod and the valve rod that is complementary with it thereof, offer pin-and-hole, and latch is set in pin-and-hole, thereby overcome valve inner complex structure, requirement on machining accuracy height, the assembling difficulty is big and when charging spool come off easily and influence the disadvantage that charges.In addition owing in pilot hole, be provided with spring, make this cylinder valve disposable to charge performance more reliable.
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing:
Fig. 1 charges preceding vertical sectional structure chart for the utility model embodiment cylinder valve;
Fig. 2 is the vertical sectional structure chart after the utility model embodiment cylinder valve charges.
Referring to Fig. 1, Fig. 2.It is an embodiment of the industrial non-once-used filling cylinder valve of the utility model, and figure acceptance of the bid note is respectively: valve handle 1 reducing 2 valve body internal threads 3 threaded stems 4 valve bodies 5 stem guiding holes 6 valve rods, 7 pin-and-holes, 8 latches, 9 spools, 10 seal rings, 11 seal bosses, 12 valve body sealing surfaces, 13 welding bench levels, 14 body cavities, 15 valve nozzle passages, 16 valve nozzles, 17 O shapes circle 18
The present embodiment cylinder valve comprises valve body 5, valve nozzle 17, valve rod 7 and valve internal component four parts.Valve body 5 one sides are provided with the valve nozzle 17 that fills, arranges refrigerant, and valve nozzle 17 is single piece with valve body 5, and the valve nozzle passage 16 of valve nozzle 17 communicates with body cavity 15.
Valve internal component is made of valve rod 7, spool 10, guide rod.Valve rod 7 is connected with valve body internal thread 3 through threaded stem 4, and threaded stem 4 tops are valve handle 1; Threaded stem 4 bottoms are provided with the groove of O type circle 18, and the groove bottom valve rod 7 of O type circle 18 dwindles gradually, make to form a body cavity 15 between valve rod 7 and the valve inwall, are provided with pilot hole 6 in the middle of valve rod 7 bottoms.Be inserted with guide rod in the pilot hole 6, guide rod and spool 10 are single piece, have pin-and-hole 8 on guide rod and the valve rod 7 that is complementary with it thereof, the Kong Weiwei of pin-and-hole 8 radially offers (can certainly adopt methods such as suitable inclination to offer), be provided with latch 9 in the pin-and-hole 8, the material of latch 9 can adopt brittle material to make, and the purpose that latch 9 is set is temporarily spool 10 is fixed together with valve rod 7 (charging refrigerant back valve core 10 will separate with valve rod 7).For make this cylinder valve disposable to charge performance more reliable, also spring should be set in the pilot hole 6, spring can be arranged between guide rod top and the pilot hole top, also can adopt the method setting that is sleeved on the guide rod.Valve body 5 can be directly and the steel cylinder welding, also can be connected with steel cylinder by valve seat again.
Tell the working procedure and the principle thereof of this cylinder valve below:
Fig. 1 shows the cross-section structure before this cylinder valve charges refrigerant, after charging end, hold valve handle 1, be rotated down valve rod 7, spool 10 is contacted with valve body sealing surface 13, when continuing rotary valve rod 7, valve body sealing surface 13 can produce reaction force gradually, when reaction force during greater than latch intensity, to cause latch 9 fractures (as shown in Figure 2), spool 10 is separated with valve rod 7, thus reached charge refrigerant before, spool 10 adeciduate purposes.At this moment, cylinder valve is in closed condition.
When using, hold valve handle 1, rotate up valve rod 7, press in the steel cylinder and wash spool 10 open this moment, and refrigerant can be discharged.
When once-used filling, because the effect of pressure, seal ring 11 contacts with seal boss 12, reaches the sealing purpose of non-once-used filling.
