DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0024] Example 1

[0025] like Figure 1-Figure 3 As shown, a fully automatic boiler feed water bypass regulating valve includes a valve body 1 and two protective shells 2 for protecting the valve body 1. The two protective shells 2 are connected by a hinge. A groove 23 matching the valve body 1 is provided in the protective shell 2. A plurality of flexible blocks 24 for blocking direct contact between the valve body 1 and the groove 23 are fixedly provided on the inner wall of the groove 23. The flexible blocks 24 are made of rubber or sponge material and are used to prevent the protective shell 2 from contacting the valve body 1 and causing damage to the valve body 1 when colliding with the protective shell 2. Rubber rings 25 are provided on both sides of the groove 23 to prevent direct contact between the protective shell 2 and the valve body 1. Two groups of locking components 21 and unlocking components 22 are respectively provided above the two protective shells 2. The locking component 21 and the unlocking component 22 cooperate to lock the two protective shells 2 to the outside of the valve body 1.

[0026] In this embodiment, when the valve body 1 is installed, the protective shell 2 is wrapped around the outside of the valve body 1 so that the flexible block 24 contacts the outer wall of the valve body 1, and the protective shell 2 contacts the valve body 1 through the rubber ring 25. The locking component 21 is inserted into the unlocking component 22, and the unlocking component 22 locks the locking component 21, so that the two protective shells 2 are fixed on the outside of the valve body 1. When a collision occurs, the protective shell 2 receives the impact force, and the protective shell 2 transmits the impact force evenly to the outer wall of the valve body 1 through the flexible block 24. Because the flexible block 24 is made of flexible material, part of the impact force is absorbed during the force transmission, thereby protecting the valve body 1.

[0027] like Figure 4-Figure 8 As shown, the two sets of locking components 21 include fixed blocks 211 respectively fixedly connected to the upper two sides of a protective shell 2, a through hole 212 is provided in the fixed block 211, a sliding cavity 213 is provided below the through hole 212, a slide plate 214 is slidably connected in the through hole 212, a connecting plate 215 sliding in the sliding cavity 213 is fixedly connected below the slide plate 214, a first spring 216 is fixedly connected to one side of the connecting plate 215, and the other end of the first spring 216 is fixedly connected to the inner wall of the sliding cavity 213, a socket 217 is provided on the end of the slide plate 214 close to the unlocking component 22, and the slide plate 214 is locked by the unlocking component 22 through the socket 217, fixing the two protective shells 2 to the outside of the valve body 1.

[0028] The two sets of unlocking components 22 include connecting blocks 221 respectively fixedly connected to the two sides above the other protective shell 2, and a slot 222 corresponding to the slide plate 214 is provided on the side of the connecting block 221 close to the locking component 21, and a sliding groove 224 is provided on the connecting block 221, and an installation cavity 223 is provided below the sliding groove 224, and the slot 222, sliding groove 224, and installation cavity 223 are connected through, and a pressing plate 225 is slidably connected in the sliding groove 224, and a horizontal plate 226 that slides in the installation cavity 223 is fixedly connected below the pressing plate 225, and a locking block 227 corresponding to the socket 217 is fixedly connected above the horizontal plate 226, and an inclined surface is provided on the locking block 227, and a second spring 228 is fixedly connected below the horizontal plate 226, and the other end of the second spring 228 is fixedly connected in the installation cavity 223.

[0029] Flanges 11 connected to the pipeline are provided on both sides of the valve body 1 , a valve cover 12 is fixed on the top of the valve body 1 by bolts, and a valve stem 13 is provided in the valve body 1 .

[0030] In this embodiment, when in use, after the protective shell 2 is wrapped around the outside of the valve body 1 and the two protective shells 2 are combined, the slide plate 214 is pushed into the slot 222. The slide plate 214 passes through the inclined surface of the locking block 227 and squeezes the locking block 227 into the installation cavity 223. After the locking block 227 drives the cross plate 226 to enter the installation cavity 223, the slide plate 214 is completely inserted into the slot 222. The second spring 228 pushes the cross plate 226 to rise, and the cross plate 226 drives the locking block 227 to be inserted into the insertion hole 217, fixing the slide plate 214 in the slot 222. When the valve body 1 needs to be repaired, the pressing plate 225 is pressed. The pressing plate 225 drives the cross plate 226 and the locking block 227 into the installation cavity 223. The first spring 216 pushes the connecting plate 215 to slide in the sliding cavity 213. The connecting plate 215 drives the slide plate 214 to slide in the through hole 212. The slide plate 214 is disengaged from the slot 222, so that the two protective shells 2 can be separated. When encountering an impact, the impact force is evenly distributed to the flexible block 24 through the protective shell 2. The flexible block 24 transmits the impact force to the valve body 1 and absorbs part of the impact force to protect the valve body 1, preventing the regulating valve from being deformed after being impacted, causing leakage, and affecting the use of the regulating valve.
