Description
Technical field
The utility model relates to valve field, more particularly, and particularly a kind of glass valves.
Background technique
In the vacuum gas filling equipment produced for light fixture, glass valves is very important parts, for controlling the opening and closing of aeration gas flow.At present, traditional glass valves is spiral, comprise the tubular valve body of threeway, spool and lid, valve body is made up of glass, spool is made of plastics, and valve body is provided with valve seat in one end, and spool arranges seal ring, spool is located in the valve body the other end, and lid is connected with spool and is connected by screw thread with this end of valve seat.During use, spool can be promoted by cap and move, thus the opening and closing of control valve.Glass valves can flow through the inner liquid doped with hardness of matter or mordant liquid, traditional only realizes sealing by seal ring, but seal ring is easy to be fallen to damage by hardness of matter or corrosive liquid, glass valves is caused to reveal, and need often to change seal ring, bother very much.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of glass valves, the good airproof performance of this glass valves, and seal ring on spool is not fragile, does not need often to change seal ring.
In order to achieve the above object, the technical solution adopted in the utility model is as follows: a kind of glass valves, comprise the tubular valve body of threeway, the spool be made of plastics and valve gap, one end of valve body is provided with valve seat, spool arranges seal ring, spool is located in the valve body the other end, lid is connected by screw thread with valve body with spool respectively, described spool is provided with hard sealing flange, described hard sealing flange and valve interior wall are sealed and matched, and described hard sealing flange is arranged on the spool between valve seat and seal ring.
The utility model is preferred: described seal ring comprises fluororubber layer and is wrapped in the tetrafluoro layer of fluororubber layer outer surface.
The utility model is preferred: described spool comprises and forms the seal bar be sealed and matched and the connecting rod be connected with valve gap with valve seat, and described seal bar and connecting rod are threaded connection.
The utility model is preferred: the outer wall of described spool is provided with the mounting groove of the annular of installing seal ring, and described mounting groove is spliced by connecting rod and seal bar.
The utility model is preferred: described connecting rod is provided with the first thread section, the outer wall of described valve body is provided with the second thread section, the rotation direction of the first thread section and the second thread section is contrary, described valve gap is respectively equipped with and the first thread section and the suitable internal thread of the second thread section.
Compared with prior art, the beneficial effects of the utility model are: be provided with hard sealing flange owing to being provided with between valve seat and seal ring, hardness of matter in such glass valves just can by hard sealing flange to stopping, seal ring can not be touched, such seal ring just not easily by hardness of matter to having cut, improve the sealability of glass valves, the seal ring in glass valves does not need often to have changed yet.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural drawing of the utility model glass valves;
Fig. 2 is the structural drawing after removing valve gap in Fig. 1;
Fig. 3 is the structural representation of spool;
Fig. 4 is the enlarged view of A in Fig. 3.
Reference character: 1, valve body; 2, spool; 3, valve gap; 4, valve seat; 5, seal ring; 6, hard sealing flange; 7, fluororubber layer; 8, tetrafluoro layer; 9, seal bar; 10, connecting rod; 11, mounting groove; 12, the first thread section; 13, the second thread section.
Embodiment
Referring to figs. 1 through Fig. 3, the utility model glass valves embodiment is described further.
A kind of glass valves, comprise the tubular valve body of threeway 1, the spool 2 be made of plastics and valve gap 3, one end of valve body 1 is provided with valve seat 4, spool 2 is arranged seal ring 5, spool 2 is located in valve body 1 the other end, lid is connected by screw thread with valve body 1 with spool 2 respectively, described spool 2 is provided with hard sealing flange 6, hard sealing flange 6 and spool 2 are wholely set, can integrated injection molding, convenient manufacture, described hard sealing flange 6 coordinates with valve body 1 inner wall sealing, and described hard sealing flange 6 is arranged on the spool 2 between valve seat 4 and seal ring 5.Hard sealing flange 6 is provided with owing to being provided with between valve seat 4 and seal ring 5, hardness of matter in such glass valves just can by hard sealing flange 6 to stopping, seal ring 5 can not be touched, such seal ring 5 just not easily by hardness of matter to having cut, improve the sealability of glass valves, the seal ring 5 in glass valves does not need often to have changed yet.
Described seal ring 5 comprises fluororubber layer 7 and is wrapped in the tetrafluoro layer 8 of fluororubber layer 7 outer surface.Traditional seal ring 5 is only fluororubber layer 7, fluororubber layer 7 price comparison is cheap, but decay resistance is poor, after its outer surface is enclosed with tetrafluoro layer 8, the corrosion resistance of seal ring 5 can be improved, make seal ring 5 not fragile, improve the sealing of glass valves, do not need often to go to change seal ring 5.
Described spool 2 comprises and forms the seal bar 9 be sealed and matched and the connecting rod 10 be connected with valve gap 3 with valve seat, and described seal bar 9 and connecting rod 10 are threaded connection.Seal bar 9 and valve seat 4 are sealed and matched, in long-term using process, seal bar 9 is easily damaged, seal bar 9 just can not well seal after damaging, and needs often to change, spool 2 is divided into seal bar 9 and connecting rod 10, and seal bar 9 and connecting rod 10 are threaded connection, whole spool 2 has not just all replaced after damaging by such seal bar 9, only needs seal bar 9 to disassemble from connecting rod 10 to replace with new just passable, reduces the cost changed.
The outer wall of described spool 2 is provided with the mounting groove 11 of the annular of installing seal ring 5, and described mounting groove 11 is spliced by connecting rod 10 and seal bar 9.Mounting groove 11 is spliced by connecting rod 10 and seal bar 9, when seal ring 5 changed by needs, as long as connecting rod 10 and seal bar 9 have been split, so just can easily change seal ring 5, do not need as traditional be seal ring 5 has been peeled firmly in mounting groove 11 come.
Described connecting rod 10 is provided with the first thread section 12, the outer wall of described valve body 1 is provided with the second thread section 13, the rotation direction of the first thread section 12 and the second thread section 13 is contrary, described valve gap 3 is respectively equipped with and the first thread section 12 and the suitable internal thread of the second thread section 13.The rotation direction of the first thread section 12 and the second thread section 13 is contrary, like this when screwing valve gap 3, spool 2 one end toward valve seat 4 can be carried, arranging like this can make spool 2 coordinate tightr with valve seat 4, better tightness, if rotation direction is identical, easily given by spool 2 and screw out, sealing is poor.
