Abstract
The utility model discloses a valve seal structure of a motor valve for a gas meter. The valve seal structure comprises a rubber valve seal and a lifting rack insertion piece, wherein an insertion piece is arranged in the rubber valve seal; three screw holes are reserved in the insertion piece; a valve seal connecting plate is fixedly connected with the lifting rack insertion piece through a reverse hook tenon; three circular holes are formed in the valve seal connecting plate; and the valve seal connecting plate is fixedly connected with the rubber seal through three screws. By adoption of the valve seal structure of the motor valve for the gas meter, the motor valve for the gas meter can be reliably used for a long time, and a user can normally use gas.
Description
Technical field
The utility model relates to a kind of diaphragm gas meter and uses the motor valve, is meant a kind of motor valve jam pot cover structure especially.
Background technique
The motor valve is the major function assembly in the diaphragm gas meter, and it is a controlled valve as circulation of combustion gas in the IC-card diaphragm gas meter (unlatching) or cut-out (closing).The motor valve can effectively cut out or open, and is to make combustion gas obtain the normal important assurance of using.But at present, most motor valve just might have been lost closing function after having used a period of time, and its main cause is that motor valve jam pot cover can come off.Motor valve jam pot cover is a rubber part, and former on structural design is elasticity and the deformation performance that utilizes rubber, slides to be inserted on the lifting rack bar; There is not suitable giving to be fixedly connected; Because jam pot cover is worked under the combustion gas environment for a long time, the erosion of chemical substances such as the toluene that receives to contain in the combustion gas, xylol can make the invisible expansion of the volume of jam pot cover own; Cause jam pot cover to come off, finally make the motor valve lose closing function from the lifting rack bar.
Summary of the invention
The purpose of the utility model is to overcome the above-mentioned defective that existing technology exists, and motor valve jam pot cover structure is improved, and improves the gas meter motor valve long term reliability, guarantees that the user normally uses combustion gas.
For achieving the above object; The solution that the utility model is taked is: a kind of motor valve for gas meter jam pot cover structure, and it comprises rubber jam pot cover and lifting rack inserts, has inserts in the rubber jam pot cover; Be reserved with three screw holes on the inserts; The jam pot cover connecting plate utilizes the barb tenon to be fixedly connected with the lifting rack inserts, and three circular holes are arranged on the jam pot cover connecting plate, and the jam pot cover connecting plate is connected with the rubber valve sealing by three pieces of screws surely.
This novel structure design has taken into full account manufacturing, the possibility of assembly technology and the reliability and stability of using process.The one, jam pot cover is improved to the non-gum spare that contains inserts by original gum spare.The 2nd, newly establish the jam pot cover connecting plate, utilize the barb tenon to be fixedly connected with the lifting rack inserts, three circular holes are arranged on the jam pot cover connecting plate, with three pieces of screws the rubber valve sealing is connected surely.The utility model is compact to design, and rationally the member shape belongs to conventional design, and component processing is convenient, and quality control is guaranteed.
Description of drawings
Fig. 1 is the stereogram of present embodiment.
Fig. 2 is the sectional view of present embodiment.
Among the figure: 1, lifting rack inserts, 2, screw, 3, the jam pot cover connecting plate, 4, the rubber jam pot cover, 5, inserts.
Embodiment
Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.
Referring to Fig. 1 and Fig. 2; A kind of motor valve for gas meter jam pot cover structure, it comprises rubber jam pot cover 4 and lifting rack inserts 1, has inserts 5 in the rubber jam pot cover 4; Be reserved with three screw holes on the inserts 5; Jam pot cover connecting plate 3 utilizes the barb tenon to be fixedly connected with lifting rack inserts 1, and three circular holes are arranged on the jam pot cover connecting plate 3, and jam pot cover connecting plate 3 is fixedly connected with rubber jam pot cover 4 by three pieces of screws 2.
Referring to Fig. 1 and Fig. 2; Described rubber jam pot cover 4 is in mould, to be vulcanized together on request by inserts 5 (alumiaum article) and the used rubber of jam pot cover to form; So both guaranteed the function of rubber jam pot cover, reduced the materials of rubber again, and can reduce rubber parts and corrode the volume overinflation because of chemical substance; Can also be fixed on the jam pot cover connecting plate 3 with screw 2 simultaneously.The described jam pot cover connecting plate of newly establishing 3 both was fixedly connected with lifting rack inserts 1, was connected with rubber jam pot cover 4 again, and rubber jam pot cover 4 is come off never.
Rubber jam pot cover 4 as shown in Figure 2, wherein inserts 5 is to be processed by aluminium, is reserved with three M2 screw holes on the inserts 5.The jam pot cover connecting plate 3 of newly establishing as shown in Figure 2 is processed with polyformaldehyde material, utilizes six barb tenons to be fixedly connected with lifting rack inserts 1, and 3 circular holes are arranged on the jam pot cover connecting plate 3, with 3 pieces of M2 screws rubber jam pot cover 4 is fixedly connected.
