Abstract
It the utility model is related to battery technology field, more particularly to a kind of lead valve sealing structure, including lead valve seat and spool, the lead valve seat is equipped with the import of lead liquid and lead liquid exports, the lead sealing surface of seat is flat seal face, the valve core sealed cover is flat gasket face, and the plain cushion is sleeved on the boss of spool front end, and boss front end is welded with fixed block.After the utility model uses new method instead, can be to avoid machining accuracy deviation and because of spool thermal deformation after, when the concentricity of spool and valve seat orifice occurs inclined, can be made up by gasket movement, be screwed by spool, tightness reaches lead liquid not water clock.
Description
Technical field：
It the utility model is related to battery technology field, and in particular to a kind of lead valve sealing structure.
Background technology：
Lead-acid battery has had the history of 130 years, has dependable performance, mature production technology, compared with Ni-MH battery and lithium electricity
The advantages such as pond cost is low.Lead-acid battery grid production and application gravity casting, the speed that lead liquid stream goes out manually rotate lead valve valve
The aperture control of core, it is consistent with the productive temp of grid casting plate machine.
Utility model content：
The technical problem to be solved by the utility model is to overcome existing technological deficiency, there is provided a kind of lead valve sealing knot
Structure.
Technical problem to be solved in the utility model is realized using following technical solution：
A kind of lead valve sealing structure, including lead valve seat and spool, the lead valve seat is equipped with the import of lead liquid and lead liquid exports,
The lead sealing surface of seat is flat seal face, and the valve core sealed cover is flat gasket face, and the plain cushion is sleeved on spool front end
On boss, boss front end is welded with fixed block.
Further, the lead valve seat is connected with spool by threaded rod, threaded hole.
Further, gap is equipped between the plain cushion and spool.
Key technology is：Lead sealing surface of seat is processed into flat seal face by anchor ring, spool conical surface seal face is changed to
Flat gasket face, sealing plain cushion leaves gap can be with axial-radial fine motion.
The beneficial effects of the utility model：, can be to avoid machining accuracy deviation and because of spool thermal deformation after using new method instead
Afterwards, when the concentricity of spool and valve seat orifice occurs inclined, it can be made up by gasket movement, be screwed by spool, tightness
Reach lead liquid not water clock.
Brief description of the drawings：
Fig. 1 is the lead valve seat construction schematic diagram of the utility model；
Fig. 2 is the valve core structure schematic diagram of the utility model；
Fig. 3 is original lead valve seat construction schematic diagram of the utility model；
Fig. 4 is original valve core structure schematic diagram of the utility model.
Embodiment：
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained, shall fall within the protection scope of the present invention.
In the description of the utility model, it is necessary to explanation, the side of the instruction such as term " vertical ", " on ", " under ", " level "
Either position relationship is based on orientation shown in the drawings or position relationship for position, is for only for ease of this practicality of description and simplification is retouched
State, rather than instruction either implies that signified device or element must have specific orientation, with specific azimuth configuration with
Operation, therefore it is not intended that limitation to the utility model.In addition, " first ", " second ", " the 3rd ", " the 4th " are only used for
Purpose is described, and it is not intended that instruction or hint relative importance.
In the description of the utility model, it is also necessary to which explanation, " sets unless otherwise clear and definite regulation and limitation, term
Put ", " installation ", " connected ", " connection " should be interpreted broadly, for example, it may be fixedly connected or be detachably connected,
Or be integrally connected, can mechanically connect or be electrically connected, can be directly connected to or by middle matchmaker
It is situated between and is connected, can is the connection inside two elements.For the ordinary skill in the art, can be as the case may be
Understand concrete meaning of the above-mentioned term in the utility model.
Embodiment one
A kind of lead valve sealing structure, including lead valve seat 1 and spool 2, lead valve seat 1 is equipped with lead liquid import 9 and lead liquid exports
10, as shown in figure 3,1 sealing surface of lead valve seat is originally anchor ring 3, it is arranged to flat seal face 5 as shown in Figure 1 now；Such as Fig. 4
Shown, 2 sealing surface of spool was originally the conical surface 4, was arranged to 6 sealing surface of plain cushion as shown in Figure 2 now, before plain cushion 6 is sleeved on spool 2
Hold boss 12 on, 12 front end of boss is welded with fixed block 11, they by spot-welded together.
Lead valve seat 1 and spool 2 are connected by threaded rod 8, threaded hole 7.
Gap is equipped between plain cushion 6 and spool 2.
Key technology is：1 sealing surface of lead valve seat is processed into flat seal face 5 by anchor ring 3, by 2 conical surface seal face 3 of spool
6 sealing surface of plain cushion is changed to, sealing plain cushion leaves gap can be with axial-radial fine motion.
Sealing surface 5 is adjusted by rotary spool 2 and the distance of plain cushion 6 adjusts lead flow quantity.
Embodiment two
The operation principle of one sealing structure of above-described embodiment：Using flexible plain cushion in the gap between spool and fixed block
Can be moved with radial-axial, compensate machining accuracy deviation and after the spool thermal deformation caused by the concentricity of spool and valve seat orifice go out
When now inclined, screwed by spool, tightness reaches lead liquid not water clock.
The advantages of basic principle and main feature and the utility model of the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
Simply illustrate the utility model principle, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
Various changes and modifications are had, these various changes and improvements fall within the scope of the claimed invention.The utility model
Claimed scope is defined by the appending claims and its equivalent thereof.
