Description

Technical Field

[0001] The utility model relates to the technical field of cone valves, in particular to a compact horizontal electric cone valve. Background Art

[0002] Fixed cone valves are widely used in hydro-generator bypasses, dams, or other locations requiring water release, as well as in the middle section of water pipelines for water treatment, municipal water distribution systems, reservoirs, petrochemical plants, and power plants. They control free discharge or continuous discharge flow. Conical valves offer a simple structure and easy operation, regulating flow by changing the distance between the sleeve and the valve body.

[0003] Chinese patent number CN201922130341.1 discloses a compact horizontal electric conical valve, which is characterized in that it includes a valve body, a sleeve, a guide cover and a drive assembly. The valve body is axially through, and a plurality of partition plates are distributed circumferentially on the inner wall of the valve body. The partition plates extend to one end of the valve body. The extended section of the partition plate is provided with a guide cone. The partition plate forms a guide channel between the guide cone and the end of the valve body. The sleeve is slidably sleeved on the outer wall of the valve body. The sleeve is used to seal the guide channel. The outer wall of the sleeve is symmetrically provided with nut brackets, and the nut brackets are fixed with nuts. The two nuts are threadedly connected with screw rods. The driving motor drives the bevel gear set to drive the rotating rod to rotate. The rotating rod drives the screw rod to rotate through the bevel gear set. The rotating rod is tilted to provide a horizontal electric conical valve with stable sliding of the sleeve and compact structure.

[0004] In the above-mentioned patent, when the valve body is applied to hot fluid, an exhaust pipe is provided through the backflow sleeve to achieve an exhaust function. However, the gas generated by the hot fluid contains components such as carbon dioxide, hydrogen sulfide, hydrogen, oxygen, nitrogen, and methane. Hydrogen sulfide is a colorless and highly toxic acidic gas. The content of hydrogen sulfide cannot be reduced during gas discharge, so that the directly discharged hydrogen sulfide gas causes environmental pollution. Utility Model Content

[0005] The purpose of the utility model is to provide a compact horizontal electric cone valve in view of the defects and shortcomings of the prior art.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a compact horizontal electric conical valve, comprising a guide sleeve, an exhaust pipe arranged on the guide sleeve, a positioning block arranged in the exhaust pipe, a square opening opened on the positioning block, a fixed block arranged on the exhaust pipe and located above the positioning block, a placement slide hole opened on the fixed block and connected to the square opening, an adsorption device for reducing the hydrogen sulfide content in the gas that can be raised and lowered and arranged on the fixed block in the square opening, a sealing member arranged at the upper end of the fixed block for sealing the placement slide hole, and a filtering device arranged on the exhaust pipe for reducing the smell of hydrogen sulfide in the gas.

[0007] Further improvements are: the adsorption device includes a lifting frame, two limit plates respectively arranged at the left and right ends of the lifting frame, a plurality of air perforations opened on the limit plates, a filling cavity formed between the two limit plates and the lifting frame, and an adsorbent filled in the filling cavity, the diameter of the adsorbent is larger than the diameter of the air perforations, the upper end of the lifting frame is located in the placement slide hole, the lifting frame can be lifted and set on the fixed block and located in the placement slide hole, and the lower end of the lifting frame is in contact with the positioning block.

[0008] A further improvement is that the adsorbent is activated alumina particles or activated carbon particles or a solid oxidant.

[0009] A further improvement is that: the upper end of the lifting frame is threadedly connected to a disassembly rod, and the upper end of the disassembly rod is provided with a lifting hook.

[0010] A further improvement is that the sealing member is an elastic plug arranged on the fixed block and located in the placement slide hole, the elastic plug is clearance-fitted or transition-fitted with the placement slide hole, the upper end of the elastic plug is provided with a fitting plate, the lower end face of the fitting plate is in contact with the upper end face of the fixed block, and the upper end face of the fitting plate is provided with a lifting handle.

[0011] A further improvement is that the elastic plug is a rubber plug or a silicone plug.

[0012] A further improvement is that the filtering device includes a disassembly sleeve that is detachably arranged on the left end face of the exhaust pipe, an air outlet opened on the disassembly sleeve for communicating with the exhaust pipe, filter cotton arranged on the disassembly sleeve and located in the air outlet for reducing the smell of hydrogen sulfide in the gas, and a limit block arranged on the disassembly sleeve and located in the air outlet for limiting the filter cotton, and the limit blocks are respectively located on the left and right sides of the filter cotton.

[0015] A further improvement is that the filter cotton is activated carbon cotton.

[0016] After adopting the above technical solution, the beneficial effects of the utility model are as follows: when the exhaust pipe discharges the gas of the hot fluid, the hydrogen sulfide content in the gas is reduced by the adsorption device, and the gap where the sliding hole is placed can be sealed by the sealing member to prevent leakage during gas discharge. After the gas passes through the adsorption device, it passes through the filtering device to reduce the smell of hydrogen sulfide in the gas. By adsorbing and filtering the discharged gas, the phenomenon of environmental pollution caused by hydrogen sulfide gas can be reduced.

[0017] Further effects: the limit plate can prevent the adsorbent from falling outward, and the air can enter the filling cavity through the air perforations, and the hydrogen sulfide in the gas is filtered by the adsorbent in the filling cavity, and the filtered gas is discharged to the outside of the exhaust pipe.

At this time, the disassembly rod is rotated to remove it from the lifting frame, and a new lifting frame with adsorbent is replaced, and the disassembly rod is installed on the new lifting frame.

[0019] Further effect: when the placement slide hole needs to be sealed, the elastic plug is aligned with the placement slide hole by holding the lifting handle and pressed toward the position of the placement slide hole until the elastic plug seals the placement slide hole.

[0020] Further effect: When the filter cotton needs to be replaced, first remove the disassembly sleeve from the exhaust pipe, then push the filter cotton to the left or right to deform it until the peripheral side of the filter cotton is detached from the limit block. When installing, align the peripheral side of the filter cotton with the limit block, and then push the filter cotton until it is completely stuck between the limit blocks.

[0021] Further effect: when the disassembly sleeve needs to be installed on the exhaust pipe, the disassembly sleeve is installed from the left side to the right side of the exhaust pipe, and the annular elastic protrusion is elastically deformed under pressure until the engaging groove matches the annular elastic protrusion, thereby fixing the disassembly sleeve on the exhaust pipe.

The disassembly sleeve 17 is loosely matched with the left end of the exhaust pipe 2, and the disassembly sleeve 17 is provided with a snap-fitting ring groove 22 for engaging with the annular elastic protrusion 21.

[0038] The annular elastic protrusion 21 is a rubber protrusion or a silicone protrusion.

[0040] The working principle of the present invention is as follows: when the exhaust pipe 2 discharges the gas of the hot fluid, the hydrogen sulfide content in the gas is reduced by the adsorbent 11, and the gap where the sliding hole 6 is placed can be sealed by the seal to prevent leakage when the gas is discharged. After the gas passes through the adsorbent 11, the filter cotton 19 can reduce the smell of hydrogen sulfide in the gas. By adsorbing and filtering the discharged gas, the environmental pollution caused by hydrogen sulfide gas can be reduced.
