Description

Technical Field

[0001] This utility model relates to the technical field of sector-shaped feed valves, specifically a sector-shaped feed valve pressure regulating device. Background Technology

[0002] The sector feed valve, also known as the electro-hydraulic sector feed valve, sector gate valve, sector ash discharge valve, electro-hydraulic sector feed valve, electro-hydraulic sector gate valve, sector discharge valve, sector gate valve, is a device used for unloading materials from dust removal equipment in cement clinker silos.

[0003] The "Electro-hydraulic Sector Valve" disclosed in publication number "CN212251236U" includes a housing, a gate actuator, and a valve. The upper end of the housing is fixedly connected to a feed port. The front of the housing is rotatably connected to the valve via a rotating shaft. The top of the valve is fixedly connected to a fixing rod. A barb block is fixedly connected to the surface of the fixing rod. A buffer device is fixedly connected to the front of the housing. The buffer device and the barb block are sized to match. A base plate is fixedly connected to the outer wall of the housing. A support is fixedly connected to the top of the base plate. The support is rotatably connected to the gate actuator via a rotating shaft.

[0004] Traditional sector-shaped feed valves lack the function of regulating the opening and closing pressure. When the load suddenly increases, the hydraulic cylinder thrust is insufficient, resulting in slow operation or even stagnation. Under light load, the system still maintains high pressure, causing energy waste. At the same time, the hydraulic cylinder does not have a closed dustproof treatment for the piston rod during operation. Hard particles such as dust and metal shavings adhere to the piston rod surface, scratching the rod surface and damaging the seals during reciprocating motion. To address these issues, we have designed a sector-shaped feed valve pressure regulating device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a fan-shaped feed valve pressure regulating device, which solves the problems of lacking the function of adjusting the opening and closing pressure, insufficient hydraulic cylinder thrust when the load suddenly increases, resulting in slow or even stagnant operation, and the system maintaining high pressure under light load, causing energy waste. At the same time, the hydraulic cylinder does not have a closed dustproof treatment for the piston rod during operation, and hard particles such as dust and metal shavings adhere to the piston rod surface, scratching the rod surface and damaging the seal during reciprocating motion.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a fan-shaped feed valve pressure regulating device, comprising a feed valve body and a hydraulic cylinder assembled on the front of the feed valve body;

[0008] An mounting sleeve is fixedly installed on the outer wall of the hydraulic cylinder. A piston rod is movably installed inside the mounting sleeve. A connecting seat that is movably connected to the drive seat is fixedly installed at one end of the piston rod. An oil inlet pipe is fixedly installed at the rear end of the top of the hydraulic cylinder. An oil outlet pipe is fixedly installed at the front side of the top of the hydraulic cylinder. A hydraulic valve is fixedly connected to the oil inlet pipe. The hydraulic valve is fixedly installed on the front of the mounting frame. A valve wheel is fixedly installed at the adjusting end of the hydraulic valve. A protective shell that is fixedly installed on the front of the mounting frame is fitted around the hydraulic valve.

[0009] The bottom ends of the hydraulic cylinder and piston rod are both fixedly equipped with support rings, and the piston rod is covered with a dust cover, with fixing rings fixedly installed at both ends of the dust cover.

[0010] Preferably, a reinforcing ring is fixedly installed on the rear side of the top of the hydraulic cylinder, and one end of the oil outlet pipe is sleeved inside the reinforcing ring.

[0011] Preferably, the outer wall of each fixing ring is fitted with a retaining ring, and the bottom of each retaining ring is movably fitted with a tightening bolt.

[0014] Preferably, a drive gear is fixedly installed on the top of the active valve plate, and a transmission gear that works in conjunction with the drive gear is fixedly installed on the top of the follower valve plate.

[0015] This utility model provides a fan-shaped feed valve pressure regulating device. Compared with the prior art, it has the following advantages:

[0016] (1) The pressure regulating device of the sector-shaped feed valve can adjust the hydraulic cylinder driving pressure during the operation of the feed valve through the cooperation between the hydraulic valve and the protective shell. This makes it convenient for the staff to adjust and match the working pressure of the hydraulic cylinder according to the material. It avoids the situation where the closing speed is slow or stagnant due to the pressure being too low, and also avoids the situation where the pressure is too high, causing energy waste or even damage to the seal or pipeline. This increases the adjustability of the feed valve during operation and improves its practicality.

[0017] (2) By combining the dust cover and the fixing ring, the piston rod of the hydraulic cylinder can be closed and dustproofed during operation, which avoids the situation where particulate material adheres to the piston rod and causes surface scratches when the feed valve is operating, thereby increasing the stability of the hydraulic cylinder during operation and extending its service life.

[0024] 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 scope of protection of the present utility model.

[0025] Example 1

[0026] Please see Figure 1-4As shown, this embodiment proposes a fan-shaped feed valve pressure regulating device, including a feed valve body 1 and a hydraulic cylinder 3 assembled on the front of the feed valve body 1. A mounting plate 101 is fixedly installed on the top of the feed valve body 1. An active valve plate 2 is movably installed on one side of the bottom of the feed valve body 1, and a follower valve plate 201 is movably installed on the other side of the bottom of the feed valve body 1. A drive seat 204 is fixedly installed on one side of the bottom of the active valve plate 2. A mounting bracket 102 is fixedly installed on the front of the feed valve body 1. A mounting sleeve 301 is fixedly installed on the outer wall of the hydraulic cylinder 3. The internal movable installation of the piston rod 306 is fixedly installed at one end of the piston rod 306 and is movably connected to the drive seat 204. The rear end of the top of the hydraulic cylinder 3 is fixedly installed with an oil inlet pipe 302, and the front side of the top of the hydraulic cylinder 3 is fixedly installed with an oil outlet pipe 303. A hydraulic valve 4 is fixedly connected to the oil inlet pipe 302. The hydraulic valve 4 is fixedly installed on the front of the mounting bracket 102. A valve wheel 401 is fixedly installed on the adjusting end of the hydraulic valve 4. The outside of the hydraulic valve 4 is covered with a protective shell 103 fixedly installed on the front of the mounting bracket 102.

[0027] In use, both the active valve plate 2 and the follower valve plate 201 are movably mounted at the bottom of the feed valve body 1. The bottom of the feed valve body 1 can be closed via the active valve plate 2 and the follower valve plate 201. A mounting bracket 102 is fixedly mounted on the front of the feed valve body 1. The hydraulic cylinder 3 is movably mounted inside the mounting bracket 102 via a mounting sleeve 301. A piston rod 306 is movably mounted inside the hydraulic cylinder 3. The hydraulic cylinder 3 is connected to an external hydraulic pump via an oil inlet pipe 302 and an oil outlet pipe 303. The extension and retraction of the piston rod 306 can drive the piston rod 306 to extend and retract by the oil inlet and outlet. The bottom end of the piston rod 306 is connected to the drive seat 204 at the bottom of the active valve plate 2. The extension and retraction of the piston rod 306 can close and open the active valve plate 2. The top of the active valve plate 2 and the follower valve plate 201 are connected via a synchronization mechanism, so that when the active valve plate 2 opens... When the valve is opened and closed, it will also drive the follower valve plate 201 to open and close synchronously. A hydraulic valve 4 is fixedly connected to the oil inlet pipe 302, and the hydraulic valve 4 is fixedly installed on the front of the mounting bracket 102. The operator can control the oil entering the hydraulic cylinder 3 by rotating the valve wheel 401 on the hydraulic valve 4, thereby adjusting the pressure of the hydraulic cylinder 3 during operation. This allows the operator to adjust and control the pressure of the hydraulic cylinder 3 according to the material, avoiding the situation where the pressure of the hydraulic cylinder 3 is too low, resulting in slow or stalled closing speed of the active valve plate 2 and the follower valve plate 201. It also avoids the situation where the pressure of the hydraulic cylinder 3 is too high, resulting in energy waste or even damage to the seals or pipelines. This increases the adjustability of the feed valve during operation and improves its practicality. The protective housing 103 can close and protect the external of the hydraulic valve 4, preventing the hydraulic valve 4 from being damaged or malfunctioning due to external forces during operation.

[0028] Example 2

[0029] Based on Example 1, such as Figure 5 As shown, support rings 307 are fixedly installed at the bottom ends of both the hydraulic cylinder 3 and the piston rod 306. A dust cover 5 is fitted over the piston rod 306, and fixing rings 502 are fixedly installed at both ends of the dust cover 5.

[0030] In use, the dust cover 5 is fitted over the piston rod 306, and the fixing rings 502 at both ends of the dust cover 5 are mounted on the support rings 307. Thus, the dust cover 5 can be installed and supported by the fixing rings 502 and the support rings 307. The dust cover 5 can provide closed protection for the piston rod 306 during operation, preventing external particles from adhering to the outer wall of the piston rod 306 and causing surface scratches and damage. This increases the stability of the hydraulic cylinder 3 during use and extends its service life.

[0031] like Figure 3 and Figure 4 As shown, a reinforcing ring 308 is fixedly installed on the rear side of the top of the hydraulic cylinder 3, and one end of the oil outlet pipe 303 is sleeved inside the reinforcing ring 308.

[0032] When in use, the reinforcing ring 308 can fix and reinforce one end of the oil outlet pipe 303 to prevent the oil outlet pipe 303 from getting tangled or squeezed during use, thus ensuring the stability of the oil outlet pipe 303 during use.

[0033] like Figure 3 and Figure 5 As shown, the outer wall of the fixing ring 502 is fitted with a retaining ring 501, and the bottom of the retaining ring 501 is movably fitted with a tightening bolt.

[0034] In use, the retaining ring 501 is fitted onto the outer wall of the fixing ring 502, and the retaining ring 501 can be tightened by tightening the bolts. Thus, the retaining ring 501 can tighten the fixing ring 502 onto the outer wall of the support ring 307, increasing the stability of the dust cover 5 during operation.

[0035] like Figure 3 and Figure 4 As shown, an oil pipe connector 304 is fixedly installed at one end of both the oil inlet pipe 302 and the oil outlet pipe 303.

[0036] In use, the oil pipe connector 304 facilitates quick connection of the oil inlet pipe 302 and the oil outlet pipe 303 to the external hydraulic pump, and also makes it convenient for staff to make block connections of the oil inlet pipe 302 and the oil outlet pipe 303 later.

[0037] like Figure 1 and Figure 2As shown, a closing plate 104 is movably installed on the front of the protective housing 103, and a safety lock 105 is fixedly installed on one side of the front of the closing plate 104.

[0038] In use, the closing plate 104 can close the front of the protective housing 103, and the safety lock 105 can lock the closing plate 104 when it is closed, ensuring the stability of the closing plate 104 when it is closed. Furthermore, opening the closing plate 104 makes it convenient for the operator to adjust the hydraulic valve 4.

[0039] like Figure 1 and Figure 2 As shown, a drive gear 202 is fixedly installed on the top of the active valve plate 2, and a transmission gear 203 that works in conjunction with the drive gear 202 is fixedly installed on the top of the follower valve plate 201.

[0040] In use, the drive gear 202 and the transmission gear 203 are meshed together, so that when the active valve plate 2 opens and closes, the drive gear 202 and the transmission gear 203 can drive the follower valve plate 201 to open and close synchronously.

[0041] Working principle: The active valve plate 2 and the follower valve plate 201 can close the bottom of the feed valve body 1. The hydraulic cylinder 3 can drive the active valve plate 2 and the follower valve plate 201 to open and close. The hydraulic valve 4 can adjust the pressure of the hydraulic cylinder 3 during operation, which allows the operator to adjust and match the pressure of the hydraulic cylinder 3 according to the material in the feed valve body 1. This avoids the situation where the pressure of the hydraulic cylinder 3 is too low, resulting in slow or stalled closing speed of the active valve plate 2 and the follower valve plate 201. It also avoids the situation where the pressure of the hydraulic cylinder 3 is too high, resulting in energy waste or even damage to the seals or pipelines. This increases the adjustability of the feed valve during operation. The dust cover 5 can close and protect the outside of the piston rod 306, preventing external particles from adhering to the outer wall of the piston rod 306 and causing surface scratches and damage. This increases the stability of the hydraulic cylinder 3 during long-term operation.
