Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0027] The present utility model provides a Figure 1-6 bidirectional stainless steel valve forging as shown, including a valve body 1, an installation shell assembly 2 is installed at the top end of the valve body 1, a lid opening and closing assembly 3 is installed at the opening at the top end of the installation shell assembly 2, buckle assemblies 4 are installed on both sides of the installation shell assembly 2, a valve stem 5 is installed inside the valve body 1, and the top end of the valve stem 5 penetrates through the installation shell assembly 2 and extends to the top of the installation shell assembly 2.

[0028] Further, the installation shell assembly 2 includes an installation shell 201, and through grooves 202 are respectively formed through the top ends on both sides of the installation shell 201. Through grooves 203 communicating with the through grooves 202 are respectively formed through the inner wall tops on both sides of the installation shell 201. An extension cylinder 204 is fixedly arranged at the outer opening of the through groove 202. The extension cylinder 204 can increase the contact area between the installation shell 201 and the cover plate 301 and improve the sealing effect. Moving sealing layers 205 are fixedly arranged on the inner walls of the through groove 203 and the extension cylinder 204. The moving sealing layers 205 can improve the sealing performance and prevent dust from entering.

[0029] The opening and closing cover assembly 3 includes two cover plates 301. The cover plates 301 movably penetrate through the through grooves 202. The adjacent sides of the two cover plates 301 are in fitting connection. The mutually remote sides of the two cover plates 301 are bent downward. Through grooves 302 adapted to the valve rod 5 are respectively formed through the middle parts of the adjacent sides of the two cover plates 301. Sealing rings 305 are fixedly arranged on the inner side walls of the through grooves 302. Gripping grooves 304 are formed in the middle parts of the mutually remote sides of the two cover plates 301. The arrangement of the gripping grooves 304 can facilitate pulling the cover plates 301. Buckling grooves 303 are formed at both ends of the mutually remote sides of the two cover plates 301. By designing the opening and closing cover assembly 3 at the top opening of the installation shell assembly 2 and fixing the opening and closing cover assembly 3 through corresponding buckle assemblies 4, by pressing the pressing plate 410, the plug plate 409 is pushed to slide into the limiting groove 408. The plug plate 409 limits the movable plate 404, so that the movable plate 404 moves downward, driving the two clamping blocks 405 to disengage from the inside of the buckling grooves 303, so that the cover plates 301 are disengaged from the clamping connection. The cover plates 301 can slide inside the through grooves 202, and the two through grooves 302 slide in the mutually remote directions, so that the top opening of the installation shell assembly 2 can be directly opened, facilitating the maintenance by the staff without disassembling the installation shell assembly 2, reducing the labor amount of the staff and improving the practicability.

[0030] The buckle assembly 4 includes a fixing plate 401, and the inside of the fixing plate 401 is hollow. A square groove 403 is formed on one side of the fixing plate 401. Installation grooves 402 are formed at both ends of the top of the fixing plate 401. An activity plate 404 is movably arranged inside the fixing plate 401. A clamping block 405 is movably penetrated through the inside of the installation groove 402, and the bottom end of the clamping block 405 is fixedly connected to one end of the top of the activity plate 404. The top end of the clamping block 405 extends into the inside of one of the buckling grooves 303, and the top end of the side of the clamping block 405 away from the installation shell 201 is inclined. The inclined setting can automatically push the clamping block 405 downward when the cover plate 301 is pushed back, which is convenient for installing the cover plate 301. Limit rods 406 are movably penetrated through both ends of the top of the activity plate 404, and both ends of the limit rods 406 are fixedly connected to the inner wall of the fixing plate 401. A return spring 407 is movably sleeved at the bottom end of the limit rod 406, and both ends of the return spring 407 are fixedly connected to the bottom end of the activity plate 404 and the inner wall of the bottom end of the fixing plate 401 respectively. A limit groove 408 is formed on one side of the activity plate 404, and the inner wall of the bottom end of the limit groove 408 is inclined. An insertion plate 409 is movably penetrated through the inside of the square groove 403, and the bottom end of one end of the insertion plate 409 close to the activity plate 404 is inclined. The tip of the insertion plate 409 is located inside the lower end of the limit groove 408. A pressing plate 410 is fixedly arranged at the end of the insertion plate 409 away from the activity plate 404. Baffles 411 are integrally formed at the top and bottom ends of the insertion plate 409, and the baffles 411 are located inside the fixing plate 401. The setting of the baffles 411 can prevent the insertion plate 409 from sliding out of the inside of the fixing plate 401.

[0031] The working principle of the present utility model:

[0032] During maintenance, by pressing the pressing plate 410, the insertion plate 409 is pushed to slide into the inside of the limit groove 408. The insertion plate 409 limits the activity plate 404, so that the activity plate 404 moves downward and compresses the return spring 407, driving the two clamping blocks 405 to disengage from the inside of the buckling groove 303, so that the cover plate 301 is disengaged from the clamping connection. The cover plate 301 can slide inside the through groove 202, so that the two through grooves 302 slide away from each other, so that the top opening of the installation shell assembly 2 can be directly opened.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
