Description

Technical Field

[0001] The utility model belongs to the field of adjustable valve forgings, and specifically relates to an adjustable valve forging. Background Art

[0002] The adjustable valve forgings in the prior art open and close the valve by directly turning the rotary wheel when adjusting the valve opening and closing angle. However, when the valve opening and closing angle needs to be finely adjusted, the simple rotary wheel structure cannot achieve fine control. When the valve is closed, the rotary wheel on the top surface used for opening and closing is easily affected by external forces, which may cause the opening and closing state of the valve to be destroyed, resulting in a waste of resources.

[0003] The Chinese patent with the publication number CN214171443U discloses an adjustable valve forging, including a valve body, wherein the upper end of the valve body has a longitudinal top delivery pipe. The adjustable valve forging of the utility model is provided with lateral delivery holes for built-in transverse lateral delivery pipes on both sides of the valve body, and lateral sliding grooves are provided on the inner side of the lateral delivery holes. The arc-shaped sliding sealing plate at the connecting end of the transverse lateral delivery pipe is inserted into the lateral sliding groove, and the angle of the transverse lateral delivery pipe can be adjusted while ensuring the lateral delivery sealing, so that the installation limitation is reduced and the application range is wider; an elastic adjustable filtering mechanism connected to the inner side of the arc-shaped sliding sealing plate is provided inside the valve body, and the filter hole size of the metal filter is adjusted by flipping the transverse lateral delivery pipe, so that the internal filtering performance inside the valve body can be freely adjusted as needed, and the functionality is greatly improved.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an adjustable valve forging to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is:

[0007] An adjustable valve forging, comprising: a valve forging, a top surface of the valve forging being provided with an opening and closing rotating shaft, a top surface of the opening and closing rotating shaft being fixedly connected with a rotating assembly, and a top surface of the valve forging being fixedly connected with a limiting assembly;

[0008] The rotating assembly comprises a shell fixedly connected to the top surface of the valve forging, the top surface of the shell is rotatably connected to a rotating rod, the bottom end of the rotating rod is fixedly connected to a small gear, and the side surface of the small gear is meshed with a large gear.

[0009] Optionally, the surface of the rotating rod is sleeved with an anti-slip sleeve, and the surface of the anti-slip sleeve is provided with grooves in a ring array for increasing friction.

[0010] Optionally, a connecting rod is fixedly connected to the top surface of the large gear, a bearing for stabilizing the large gear is sleeved on the top end of the connecting rod, and the bearing is fixedly connected to the inner top wall of the outer shell.

[0011] Optionally, an opening and closing rotating shaft is fixedly connected to the bottom end of the large gear, and the opening and closing rotating shaft can drive the valve inside the valve forging to open and close.

[0012] Optionally, the limit assembly includes a limit ring fixedly connected to the top surface of the valve forging, the surface of the limit ring is provided with a plurality of threaded holes in an annular array, the internal threads of the threaded holes are connected to a limit rod, and the surface of the limit rod is sleeved with a protective sleeve.

[0014] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described below at the same time:

[0015] 1. Through the setting of the rotating assembly, when it is necessary to finely adjust the internal opening and closing angle of the valve, rotate the rotating rod to drive the small gear fixed at the bottom to rotate, and the small gear drives the large gear meshing on the side to rotate. Due to the different circumferences and tooth ratios of the small gears, the rotation of the small gear will cause the large gear meshing on the side to rotate slowly, and the large gear drives the opening and closing shaft fixedly connected to the bottom to rotate slowly, so that the internal opening and closing angle of the valve forging can be slowly and finely adjusted, thereby achieving the purpose of facilitating the fine adjustment of the internal opening and closing angle of the valve forging and improving practicality.

[0016] 2. Through the setting of the limit assembly, when the rotating rod is rotated to close the inside of the valve forging, the two limit rods are threadedly connected to the two sides of the corresponding position according to the position of the rotating rod above the limit ring, so as to limit the rotating rod and prevent the rotating rod from rotating due to external force and opening the inside of the valve forging, thereby protecting the opening and closing state of the valve forging and avoiding waste of resources.

DETAILED DESCRIPTION

[0027] The utility model will now be further described in detail with reference to the accompanying drawings.

[0028] See also Figure 1-4 As shown, in this embodiment, an adjustable valve forging is provided, including: a valve forging 1, the top surface of the valve forging 1 is provided with an opening and closing rotating shaft, the top surface of the opening and closing rotating shaft is fixedly connected to a rotating component 2, and the top surface of the valve forging 1 is fixedly connected to a limiting component 3.

[0029] One aspect of the application of this embodiment is that the large gear 24 drives the opening and closing shaft fixedly connected to the bottom surface to rotate slowly, so that the opening and closing angle inside the valve forging 1 can be adjusted slowly and finely, which is convenient for finely adjusting the opening and closing angle inside the valve forging 1 and improving practicality. It should be noted that all electrical equipment involved in this application can be powered by batteries or external power supplies.

[0030] like Figure 2As shown, the surface of the rotating rod 22 of this embodiment is sleeved with an anti-skid sleeve 4, and the surface of the anti-skid sleeve 4 is provided with grooves in a ring array for increasing friction. The top surface of the large gear 24 is fixedly connected with a connecting rod 5, and the top end of the connecting rod 5 is sleeved with a bearing 6 for stabilizing the large gear 24, and the bearing 6 is fixedly connected to the inner top wall of the outer shell 21. The anti-skid sleeve 4 can increase the surface friction of the rotating rod 22 to avoid the situation of slipping out of the hand when holding it. At the same time, when the large gear 24 rotates, the connecting rod 5 rotates inside the bearing 6, so that the large gear 24 rotates more smoothly to avoid affecting the transmission effect.

[0031] like Figure 4 As shown, a frame is provided on the side of the valve forging 1 of this embodiment, and a filter screen 7 for intercepting larger debris is provided inside the frame. The filter screen filters and intercepts the larger debris to prevent it from entering the valve forging 1 and causing valve clogging.

[0034] By setting the rotating component 2, when it is necessary to finely adjust the internal opening and closing angle of the valve, the rotating rod 22 is rotated to drive the small gear 23 fixed at the bottom to rotate, and the small gear 23 drives the large gear 24 meshing on the side to rotate. Since the circumference and gear ratio of the small gear 23 are different, the rotation of the small gear 23 will cause the large gear 24 meshing on the side to rotate slowly, and the large gear 24 drives the opening and closing shaft fixedly connected to the bottom to rotate slowly, so that the internal opening and closing angle of the valve forging 1 can be slowly and finely adjusted, thereby achieving the purpose of facilitating the fine adjustment of the internal opening and closing angle of the valve forging 1 and improving practicality.

[0035] Embodiment 2:

[0036] In this embodiment, the limit assembly 3 includes a limit ring 31 fixedly connected to the top surface of the valve forging 1, and a plurality of threaded holes are formed in an annular array on the surface of the limit ring 31. The inner threads of the threaded holes are connected to the limit rod 32, and the surface of the limit rod 32 is sleeved with a protective sleeve 33.

[0037] Through the setting of the limit assembly 3, when the rotating rod 22 is rotated to close the inside of the valve forging 1, the two limit rods 32 are threadedly connected to the two sides of the corresponding position according to the position of the rotating rod 22 above the limit ring 31, so as to limit the rotating rod 22 and prevent the rotating rod 22 from rotating due to external force and opening the inside of the valve forging 1, thereby protecting the opening and closing state of the valve forging 1 and avoiding waste of resources.
