Abstract
The utility model relates to a non-duplicated filling valve. The non-duplicated filling valve comprises a valve body, wherein the valve body is provided with an axially cut-through ventilating chamber; an air inlet communicated with the ventilating chamber is formed in the valve body; a valve rod capable of moving back and forth is arranged inside the ventilating chamber in a penetrating manner and provided with a sealing part sealed with the inner wall of the ventilating chamber; the sealing part is positioned above the air inlet; a ventilating interspace is reserved between the valve rod arranged below the sealing part and the inner wall of the ventilating chamber; a valve core is arranged inside the ventilating chamber, positioned below the air inlet and the valve rod and provided with an axially cut-through air outlet communicated with the ventilating chamber, and comprises a sealing core positioned inside the air outlet; the sealing core comprises an core column and a wing frame arranged on the core column and extending towards the two sides respectively; the wing frame is connected on the valve core; an obconical sealing ring is arranged at the lower end of the core column; the valve rod rightly faces the core column; an obconical sealing opening corresponding to the sealing ring is formed in the air outlet below the sealing core and can be blocked by the sealing ring. According to the utility model, when the obconical sealing ring falls into the obconical sealing opening, because the obconical structure is adopted, the sealing effect is good.
Description
Technical field
The utility model relates to a kind of filling valve.
Background technique
Fill medium in steel cylinder time, need to fill with filling valve.For fear of the repeated charging problem having produced because of carelessness after having filled, need filling valve must not carry out repeated charging.In order to address this problem, the Chinese utility model patent that the patent No. is 201320340202.1 provides a kind of non-valve of resetting that repeats, and it pushes up under ball sealer by being about under valve rod, thereby realizes the sealing after having filled by ball sealer.Its shortcoming also existing is: ball seal is not thorough, thereby and spheroid in the time that filled medium impacts, easily roll and can not realize sealing.
Summary of the invention
In order to overcome the above-mentioned deficiency of existing non-refillable valve, the utility model provides a kind of non-refillable valve of better tightness.
The technical scheme in the invention for solving the technical problem is: a kind of non-refillable valve, comprise valve body, and described valve body has the venting cavity of axial perforation, and described valve body is provided with the suction port with described venting cavity UNICOM;
In described venting cavity, be equipped with reciprocating valve rod, described valve rod has the sealed department with described venting cavity inner wall sealing, described sealed department is positioned at the top of described suction port, between the valve rod of described sealed department below and the inwall of described venting cavity, has ventilation space;
In described venting cavity, be also provided with spool, described spool is positioned at the below of described suction port and valve rod, and described spool has the air outlet hole of venting cavity axial perforation and described UNICOM,
Also comprise that one is positioned at the sealed core of described air outlet hole, described sealed core comprises stem stem and the wing frame extending to both sides respectively of being located on described stem stem, and described wing frame is connected on described spool, and the lower end of described stem stem is provided with the seal ring of inverted cone;
Described valve rod is just to described stem stem;
The sealed mouth in the air outlet hole of described sealed core below with the inverted cone corresponding with described seal ring, described sealed mouth can be by described seal ring shutoff;
Further, the upper end of described valve rod is provided with handle, between described handle and the upper-end surface of valve body, is provided with safety buckle.
Further, described spool is threaded connection in described venting cavity.
Further, the upper end of the sidewall of described spool is provided with two embedding mouths, and described wing frame embeds in described embedding mouth.
In use, by suction port air inlet, gas flows out through the air outlet hole of ventilation space, spool from suction port the utility model.After filling, valve rod is pushed away downwards, valve rod promotes stem stem, make to rupture between wing frame on stem stem and stem stem, stem stem falls, thereby the lower end of stem stem is provided with in the sealed mouth that the seal ring of inverted cone falls into inverted cone, form sealing, thereby effectively avoid repeated charging.
The beneficial effects of the utility model are: can realize non-refillable, use safer; After the seal ring of inverted cone falls in the sealed mouth of inverted cone, owing to being that inverted cone coordinates, good sealing effect.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is explosive view of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
With reference to Fig. 1, Fig. 2, a kind of non-refillable valve, comprises valve body 1, and described valve body 1 has the venting cavity of axial perforation, and described valve body 1 is provided with the suction port 2 with described venting cavity UNICOM;
In described venting cavity, be equipped with reciprocating valve rod 3, described valve rod 3 has the sealed department with described venting cavity inner wall sealing, described sealed department is positioned at the top of described suction port 2, between the valve rod of described sealed department below and the inwall of described venting cavity, has ventilation space;
In described venting cavity, be also provided with spool 4, the spool 4 described in the present embodiment is threaded connection in described venting cavity.Described spool 4 is positioned at the below of described suction port 2 and valve rod, and described spool 4 has the air outlet hole of venting cavity axial perforation and described UNICOM;
Also comprise that one is positioned at the sealed core 5 of described air outlet hole, described sealed core 5 comprises stem stem 6 and is located at the wing frame 7 extending to both sides respectively on described stem stem 6, described wing frame 7 is connected on described spool 4, the upper end of the sidewall of spool 4 described in the present embodiment is provided with two embedding mouths, and described wing frame 7 embeds in described embedding mouth.The lower end of described stem stem 6 is provided with the seal ring 8 of inverted cone;
Described valve rod 3 is just to described stem stem 6;
The sealed mouth in the air outlet hole of described sealed core below with the inverted cone corresponding with described seal ring 8, described sealed mouth can be by described seal ring shutoff.
In use, by suction port 2 air inlets, gas flows out through the air outlet hole of ventilation space, spool 4 from suction port.After filling, valve rod 3 is pushed away downwards, valve rod 3 promotes stem stem 6, make fracture between wing frame 7 on stem stem 6 and stem stem 6, stem stem 6 falls, and falls in the sealed mouth of inverted cone thereby the lower end of stem stem is provided with the seal ring 8 of inverted cone, form sealing, thereby effectively avoid repeated charging.
