Description

Technical Field

[0001] The invention relates to the technical field of hidden valves, in particular to an adjustable hidden valve. Background Art

[0002] A valve is a control component in a fluid conveying system. It has functions such as shutoff, regulation, diversion, backflow prevention, pressure stabilization, diversion or overflow pressure relief. In particular, a valve used to control liquid flow usually has a valve plate arranged in a pipeline structure, and the valve plate is connected to a knob arranged outside the pipeline structure through a threaded rod. The threaded rod is threadedly connected to the pipeline. Turning the knob drives the threaded rod to rotate, which can drive the valve plate to rotate or move horizontally, thereby controlling the opening and closing of the valve.

[0003] The current valve has certain shortcomings:

[0004] 1. During the use of current valves, the valve stem and valve handle are usually directly exposed to the outside world. However, the valve stem is exposed to the outside world, which is easy for operators to touch it by mistake. In addition, the valve handle is generally fixed on the stem. After the valve is used for a long time, dust will enter the connection, making it more laborious to rotate.

[0005] 2. Since the internal space of the valve is smaller than that of the pipeline, when the valve is used to control fluids with high density such as mud, it is easy to cause the fluid to be blocked in the valve, affecting the transmission efficiency of the fluid. Moreover, when the fluid is transported, the flow rate of the fluid cannot be changed, which limits the application scenarios.

[0006] 3. When the valve is installed, the handle is exposed to the outside world, so when the valve is transported, the handle is hit and bent, which damages the valve and causes water leakage due to insufficient sealing at the joint. Summary of the invention

[0007] The object of the present invention is to provide an adjustable concealed valve to solve the related problems raised in the above background technology.

[0008] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an adjustable hidden valve, comprising a valve body, a valve handle is provided at the middle position of the top of the valve body, a locking gear is provided at the top of the outer side of the valve handle, an opening and closing member is provided at the bottom of the valve handle, water inlets are provided on both sides of the opening and closing member, a rotating shaft is provided at the bottom inside the opening and closing member, fan blades are provided at the bottom of the outer side of the rotating shaft, a driven gear is provided at the top of the rotating shaft, a third receiving groove is provided on both sides of the top of the valve body, connecting flanges are provided on both sides of the valve body, shielding sleeves are slidably provided on one side where two groups of the connecting flanges are close to each other, a rectangular groove is provided on one side where the tops of the two groups of the shielding sleeves are close to each other, a hidden rotating handle assembly is sleeved on the outer side of the valve handle, and a speed change assembly is provided at the middle position of the two ends of the top of the valve body.

[0009] Preferably, the hidden handle assembly includes a valve stem, an arc-shaped rack, a first receiving groove, a rectangular sleeve, a telescopic rod, a connecting rod, a second receiving groove and a spring. The valve stem is sleeved on the outside of the valve handle, and rectangular sleeves are provided on both sides of the outside of the valve stem. Three groups of second receiving grooves are evenly provided at both ends of the inside of the valve stem, and first receiving grooves are provided at both ends of the valve stem.

[0010] Preferably, the speed change assembly includes a mounting plate, a transmission gear, a first active gear, a support plate, a second active gear, a transmission shaft, a driving motor, a rack, a slide plate and a fastening bolt. The support plate is provided with two groups of two ends respectively located at the top of the valve body, the tops of the two groups of support plates are provided with mounting plates, the inside of the mounting plates is slidably provided with slide plates, transmission shafts are provided on both sides of the bottom of the slide plate, the outer sides of the two groups of transmission shafts are provided with transmission gears, the outer sides of the two groups of transmission gears are sleeved with racks, the bottoms of the two groups of transmission shafts are respectively provided with the first active gear and the transmission shaft, a driving motor is provided on one side of the top of the slide plate, and a fastening bolt is threadedly connected to one end of the front side of the slide plate.

[0011] Preferably, a groove is provided on one side of the inner bottom of the third receiving groove, and the groove and the rectangular sleeve plate are adapted to each other.

[0012] Preferably, one end of the spring is fixedly connected to the interior of the second receiving groove.

[0013] Preferably, an annular sliding groove is provided at the edge of one side of the connecting flange, and the shielding sleeve and the annular sliding groove are adapted to each other.

[0014] Preferably, the arc-shaped rack and the engaging gear are both located at the same horizontal position, and the arc-shaped rack and the engaging gear are meshed with each other.

[0015] Preferably, a motor compartment is provided on the outer side of the driving motor, and the output end of the driving motor is adapted to a set of transmission shafts.

[0016] Preferably, a through slot is provided at one front end of the mounting plate, and one front end of the fastening bolt passes through the through slot and is adapted to the through slot.

[0017] Preferably, limit stops are provided on both sides of the valve stem.

[0018] Compared with the prior art, the present invention provides an adjustable hidden valve, which has the following beneficial effects:

[0019] 1. The present invention effectively prevents operators from misoperating the valve stem by hiding the valve stem inside the third storage groove. When rotating the valve handle, if the valve has not been used for a long time, the connection will rust and corrode, which will cause greater friction between the valve stem and the valve. Therefore, when the valve stem and the valve handle are connected, the connection position can be changed, and the power arm can be increased by rotating the valve handle. Therefore, it is more labor-saving to rotate the valve handle, which is convenient for adjusting the valve stem to increase the valve.

[0020] 2. The present invention utilizes fan blades to rotate inside the opening and closing member. When encountering a fluid with a higher density, the rotation of the fan blades can transport and stir the fluid to prevent the fluid from being blocked inside the valve body. At the same time, the first driving gear, the second driving gear and the driven gear can be transmitted to change the rotation speed of the driven gear, thereby changing the rotation speed of the fan blades, which can make the fluid transport faster and change different speeds according to actual needs.

[0021] 3. The present invention places the valve stem inside the third receiving groove and then rotates the shielding sleeve 180 degrees so that the rectangular groove on the shielding sleeve rotates to the bottom. This can not only prevent the valve stem from sliding during transportation but also reduce the impact on the valve stem. At the same time, the shielding sleeve can protect the outer side of the valve body. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Embodiment 1, as Figure 4-5 As shown, when the valve body 1 needs to be opened to convey fluid, the shielding sleeve 12 can be rotated at this time, and the rectangular groove 14 can be rotated to the top of the third receiving groove 7, and then the valve stem 201 is slid upward along the valve handle 13, and the valve stem 201 drives the arc rack 202 to move upward to the same height as the engaging gear 6, and then pushes the connecting rod 206 to drive the arc rack 202 to mesh with the engaging gear 6, and then the two sets of rectangular sleeve plates 204 are slid close to each other, and the connecting rod 206 is moved to the inside of the rectangular sleeve plate 204 to complete the fixation of the arc rack 202. At this time, the valve stem 201 can be rotated, and the valve handle 13 is driven to rotate through the cooperation of the second receiving groove 207 and the engaging gear 6 to open the valve body 1 to work. When it is more difficult to rotate the valve handle 13, the valve stem 201 is pulled to one end at this time, and the two sets of arc racks 202 at one end are re-engaged with the engaging gear 6. At this time, the power arm for rotating the valve stem 201 is increased, which is more labor-saving.

[0042] Embodiment 2, as Figure 4-5 As shown, when conveying a fluid with a relatively high density, the fastening bolt 310 can be rotated to release the slide plate 309. At this time, the slide plate 309 can be slid to drive a group of second driving gears 305 to engage with the driven gear 5, and the drive motor 307 is turned on to work. The transmission shaft 306 simultaneously drives the transmission gear 302 and the second driving gear 305 to rotate, and the transmission shaft 306 drives another group of transmission gears 302 to rotate. The rotating second driving gear 305 drives the driven gear 5 and the rotating shaft 4 to rotate, and the rotating shaft 4 drives the fan blades 11 to rotate inside the opening and closing member 10, so as to stir and convey the fluid with a relatively high density, and prevent the blockage inside the valve body 1. At the same time, the diameters of the first driving gear 303 and the second driving gear 305 are different, and the speeds of driving the driven gear 5 to rotate are different, which can adapt to different flow rate requirements.

[0043] Working principle: when the valve body 1 needs to be opened to convey fluid, the shielding sleeve 12 can be rotated to rotate the rectangular groove 14 to the top of the third receiving groove 7, and then the valve stem 201 is slid upward along the valve handle 13, and the valve stem 201 drives the arc-shaped rack 202 to move upward to the same height as the engaging gear 6, and then the connecting rod 206 is pushed to drive the arc-shaped rack 202 to mesh with the engaging gear 6, and then the two sets of rectangular sleeves 204 are slid close to each other, and the connecting rod 206 is moved to the inside of the rectangular sleeve 204 to complete the fixation of the arc-shaped rack 202, and then the valve stem 201 can be rotated, and the valve handle 13 is driven to rotate through the cooperation of the second receiving groove 207 and the engaging gear 6, and the valve body 1 is opened to work;

[0044] When conveying a fluid with a higher density, the sliding plate 309 can be used to drive a set of second driving gears 305 to engage with the driven gear 5. The rotating second driving gear 305 drives the driven gear 5 and the rotating shaft 4 to rotate. The rotating shaft 4 drives the fan blades 11 to rotate inside the opening and closing member 10, so as to stir and convey the fluid with a higher density, thereby preventing blockage inside the valve body 1.

[0045] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions of the technical solution of the present invention by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the present invention.
