[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Please see Figures 1 to 5This utility model provides a technical solution: a locking valve for heating, comprising: a valve body 1, which is the core functional carrier of the valve, integrating key components such as valve core and flow channel, responsible for controlling the on / off and flow of hot water in the heating pipeline, such as adjusting the opening by rotating the valve core, which is the basic component for realizing heating flow control. At the same time, its top provides a fixed support for the lock seat 2, ensuring a stable connection between the locking structure and the valve body 1. The top of the valve body 1 is fixedly connected to the lock seat 2, which is the core installation base for access control. The internal lock hole 3 is the insertion interface for a special key, such as a mechanical key. Only by inserting a matching key into the lock hole 3 and operating it can the valve's opening / closing or adjustment permissions be unlocked, preventing users from operating it without authorization. The lock seat 2 has a lock hole 3 inside.

[0024] It also includes: a fixed base 4 is fixedly connected to the outside of the lock base 2. The fixed base 4 is designed to fix the baffle 5. The baffle 5 is slidably connected inside the fixed base 4. The baffle 5 is designed to cooperate with the rubber sheet 10 to facilitate the sealing of the lock hole 3. A sliding rod 6 is fixedly connected to the top of the baffle 5. The sliding rod 6 is designed to facilitate the installation of the push plate 7 and the push spring 8. A push plate 7 is fixedly connected to the outside of the sliding rod 6. The push plate 7 is designed to drive the baffle 5 under the push of the push spring 8. The push spring 8 is sleeved on the outside of the sliding rod 6. A limit plate 9 is fixedly connected to the rear end of the sliding rod 6. The limit plate 9 is designed to limit the sliding rod 6. A rubber sheet 10 is fixedly connected to the bottom end of the baffle 5. The rubber sheet 10 is designed to seal the lock hole 3.

[0025] The fixed base 4 is L-shaped, and the outer side of the sliding rod 6 is slidably connected to the inside of the fixed base 4. The push spring 8 is designed to push the push plate 7.

[0026] The front end of the push spring 8 is fixedly connected to the rear side of the push plate 7, and the rear end of the push spring 8 is fixedly connected to the front side of the fixed base 4. The fixed push spring 8 has better recovery performance.

[0027] The front side of the limiting piece 9 contacts the rear end of the fixed base 4. The limiting piece 9 is designed to limit the sliding rod 6. The bottom end of the rubber piece 10 is in close contact with the top of the lock base 2. The rubber piece 10 is located directly above the lock hole 3 and covers the lock hole 3.

[0028] When the key needs to be inserted into the lock hole 3 to unlock the valve, push the baffle 5 by hand. The baffle 5 will drive the push plate 7 to squeeze the push spring 8, and the baffle 5 will cause the rubber plate 10 to no longer block the lock hole 3. The positioning hole 12 will be at the same level as the positioning button 13. At this time, the positioning button 13 can be rotated so that the protrusion of the positioning button 13 engages with the positioning hole 12. The key can then be inserted into the lock hole 3 to unlock the lock seat 2. After unlocking, the key is pulled out of the lock hole 3. The positioning button 13 is then rotated so that the protrusion of the positioning button 13 no longer engages with the positioning hole 12. The push spring 8 will then push the push plate 7, thereby pushing the sliding rod 6 and the baffle 5, so that the baffle 5 and the rubber plate 10 close the lock hole 3.

[0029] By having the baffle 5 and the rubber sheet 10 work together to seal the keyhole 3, the keyhole 3 is provided with physical protection to prevent various impurities in the air from falling into the keyhole 3, thereby reducing the probability of the keyhole 3 rusting and clogging, ensuring that the key can be inserted normally, and eliminating the need for additional maintenance.

[0030] Example 2

[0031] In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that two limiting seats 11 are fixedly connected to the top of the lock seat 2. The limiting seats 11 are designed to limit the baffle 5. The two limiting seats 11 are closely attached to the outside of the baffle 5 and are symmetrically distributed.

[0032] The baffle 5 has a positioning hole 12, and the rear end of the fixed base 4 is rotatably connected to a positioning button 13. When the positioning hole 12 engages with the protrusion on the positioning button 13, the baffle 5 can be locked.

[0033] The positioning button 13 has a protrusion that engages with the positioning hole 12.
