Description

Technical Field

[0001] This utility model relates to the field of control valves, specifically a modular quick-installation intelligent control valve. Background Technology

[0002] Gas is a general term for gaseous fuels. It can burn and release a large amount of heat. Gas is an important resource. Whether it is cooking at home or engaging in some commercial activities, it is indispensable. There are many appliances that use gas as an energy source, such as gas water heaters. When gas pipelines are in use, they need to be equipped with intelligent control valves for controlling the opening, closing and flow regulation.

[0003] Regarding patents for intelligent control valves, a search revealed Chinese patent CN215981117U, which discloses a remote intelligent control valve for industrial and commercial gas users. The patent includes a control component installed on a gas pipeline. The control component comprises a housing and a digit wheel fixedly installed inside the housing. A gas passage is opened inside the housing. A control shaft is rotatably mounted on the outer side of the digit wheel, extending into the gas passage and fixedly mounted with fan blades arranged in a circular array. A digital disk arranged in a linear array is rotatably mounted inside the digit wheel, with protruding contacts on the digital disks. Springs corresponding to each contact are provided inside the housing. The fan blades are driven to rotate, causing the digital disks to rotate so that the contacts contact the springs.

[0004] While the aforementioned device can achieve zero readings on all digital panels when the user's remaining balance is zero, causing the contacts on the digital panels to engage with the reeds and control the drive unit to close the valve, thus achieving intelligent control, in actual use, the intelligent control valve is generally fixed to the pipeline using a screw connection. When disassembling the intelligent control valve from the pipeline, uneven torque applied during disassembly (causing the screw end to tilt inside the pipeline) may lead to stress concentration at the valve or pipeline interface, causing problems such as valve body cracks and pipeline deformation. Especially for pipelines made of brittle materials such as cast iron and plastic, the impact force during disassembly can easily cause irreparable damage. Utility Model Content

[0005] The purpose of this invention is to provide a modular, quick-installation intelligent control valve to address the deficiencies mentioned in the background section.

[0006] To achieve the above objectives, a modular quick-install intelligent control valve is provided, comprising an intelligent control valve body, an actuator mounted on the bottom of the intelligent control valve body, an inlet seat fixedly disposed on one side of the intelligent control valve body, and an outlet seat fixedly disposed on the other side of the intelligent control valve body. A quick-install seat A is mated to the surface of the inlet seat, and a quick-install seat B is mated to the surface of the outlet seat. An outlet pipe is fixedly connected to the end of quick-install seat B, and an inlet pipe is fixedly connected to the end of quick-install seat A. A quick-install groove is formed on the surface of quick-install seat A, a quick-install strip is fixedly disposed on the surface of the inlet seat, and a medium inlet is formed inside the inlet seat.

[0007] Furthermore, two sets of limiting grooves are provided on the inner circumference of the medium inlet, a filter cylinder is provided on one side of the limiting groove, multiple sets of filter holes are evenly provided on the filter cylinder, the filter cylinder is frustum shaped, and a buffer cone is fixedly provided at the bottom of the filter cylinder, the buffer cone is conical.

[0008] Furthermore, two sets of limiting seats are fixedly provided at the end of the filter cartridge. The size of the limiting seats is adapted to the limiting groove. The limiting seats are snapped into the inside of the limiting groove. The cross-section of the limiting seats and the limiting groove is set in a dovetail shape. The fixing bolts pass through the countersunk holes opened on the limiting seats and are screwed into the screw holes opened at the bottom of the limiting groove.

[0009] Furthermore, two sets of quick-release slots are provided on the end face of quick-release seat A, and two sets of quick-release strips are fixedly provided on the end face of the inlet seat. The dimensions of the quick-release strips and quick-release slots are adapted to each other. The two sets of quick-release strips are respectively inserted into the two sets of quick-release slots. The quick-release strips are inserted into the quick-release slots and fixed by two sets of bolts.

[0010] Furthermore, both the top and bottom of the inlet seat and the quick-release seat A are provided with sealing openings. A sealing gasket is provided on the upper side of the sealing opening. A locking seat is fixedly provided on the top of the sealing gasket. The locking seat is respectively engaged in the sealing openings on the inlet seat and the quick-release seat A and is fixed by two sets of bolts.

[0011] Furthermore, the intelligent control valve body is vertically positioned and assembled between quick-installation seat A and quick-installation seat B through inlet and outlet seats. The inlet seat and quick-installation seat A are quick-installed through quick-installation grooves and quick-installation strips, and the outlet seat and quick-installation seat B are quick-installed through quick-installation grooves and quick-installation strips.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model uses a vertical insertion method to position and install the intelligent control valve body between quick-installation seat A and quick-installation seat B. During the quick-installation process, two sets of quick-installation slots and quick-installation strips can be used for rapid positioning and installation. The vertical insertion method replaces the traditional method of using screws or flanges, which greatly shortens the installation time and eliminates the flange docking step, making it especially suitable for confined spaces or high-altitude operations.

[0014] 2. This utility model uses an upward lifting method to disassemble the intelligent control valve body on the pipeline, thus avoiding valve body cracks and pipeline deformation during valve disassembly. After the inlet seat and quick-install seat A are connected, they can be sealed through the sealing port, sealing gasket, and locking seat to prevent leakage at the connection.

[0015] 3. When the intelligent control valve body is closed, the buffer cone can guide the airflow to change direction smoothly, reduce the pressure fluctuation caused by sudden changes in flow velocity, reduce the impact force on the valve core inside the intelligent control valve body, and weaken the intensity of the pressure wave in the gas hammer effect like a buffer pad, reduce the vibration and damage to the equipment caused by the gas hammer impact, improve the service life of the valve body, and ensure the stability and safety of the gas system operation.

[0023] Please see Figure 1-6 This utility model provides a modular quick-installation intelligent control valve, including an intelligent control valve body 1, an actuator 2 installed at the bottom of the intelligent control valve body 1, an inlet seat 3 fixedly installed on one side of the intelligent control valve body 1, an outlet seat 4 fixedly installed on the other side of the intelligent control valve body 1, a quick-installation seat A31 mated to the surface of the inlet seat 3, a quick-installation seat B41 mated to the surface of the outlet seat 4, an outlet pipe 42 fixedly connected to the end of the quick-installation seat B41, an inlet pipe 32 fixedly connected to the end of the quick-installation seat A31, a quick-installation groove 311 opened on the surface of the quick-installation seat A31, a quick-installation strip 312 fixedly installed on the surface of the inlet seat 3, and a medium inlet 316 opened inside the inlet seat 3.

[0024] In a preferred embodiment, two sets of limiting grooves 317 are provided on the inner circumference of the medium inlet 316. A filter cylinder 319 is provided on one side of the limiting groove 317. Multiple sets of filter holes 3191 are evenly provided on the filter cylinder 319. The filter cylinder 319 is frustum shaped. A buffer cone 3192 is fixedly provided at the bottom of the filter cylinder 319. The buffer cone 3192 is conical.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown: Inside the inlet seat 3, a filter cartridge 319 is positioned and installed via two sets of limiting grooves 317 and limiting seats 318. The filter cartridge 319 is frustum-shaped and can filter the gas. At the same time, a conical buffer cone 3192 is fixedly installed at the bottom of the filter cartridge 319. The filter cartridge 319 adopts a frustum-shaped tapering design, which provides a larger effective filtration area than a cylindrical filter cartridge, reducing gas flow resistance and pressure loss. The filter cartridge 319, through its numerous filter holes 3191, can filter the gas medium, effectively intercepting impurities and particles in the gas, preventing them from entering downstream pipelines and equipment, reducing equipment wear and blockage caused by impurities, and lowering maintenance costs and failure frequency. At the same time, it ensures the continuity of gas delivery, improves filtration efficiency and gas delivery stability, and guarantees gas supply quality and safe system operation.

[0026] Two sets of limiting seats 318 are fixedly installed at the end of the filter cartridge 319. The size of the limiting seat 318 is adapted to the limiting groove 317. The limiting seat 318 is snapped into the inside of the limiting groove 317. The cross-section of the limiting seat 318 and the limiting groove 317 is set in a dovetail shape. The fixing bolt passes through the countersunk hole opened on the limiting seat 318 and is screwed into the screw hole opened at the bottom of the limiting groove 317.

[0027] The filter cartridge 319 is shaped like a frustum with a gradually narrowing design. On the one hand, it can effectively increase the filtration area within a limited space, thereby improving the amount of impurities intercepted and the filtration efficiency. On the other hand, the gradually narrowing structure facilitates the accumulation and settling of impurities at the narrow end, reducing filter pore blockage and making cleaning and maintenance easier. In addition, the gas forms a velocity gradient when passing through the filter cartridge, which promotes impurity separation, enhances the filtration effect, and reduces gas flow resistance, ensuring smooth and stable gas supply.

[0028] In a preferred embodiment, the quick-installation slot 311 has two sets of quick-installation base A31 on its end face, and the quick-installation strip 312 is fixedly provided on the end face of the inlet base 3. The quick-installation strip 312 and the quick-installation slot 311 are matched in size. The two sets of quick-installation strips 312 are respectively inserted into the two sets of quick-installation slots 311. The quick-installation strips 312 are inserted into the quick-installation slots 311 and fixed by two sets of bolts.

[0029] Both the top and bottom of the inlet seat 3 and the quick-release seat A31 are provided with sealing openings 313. A sealing gasket 314 is provided on the upper side of the sealing opening 313. A locking seat 315 is fixedly provided on the top of the sealing gasket 314. The locking seat 315 is respectively snapped into the sealing openings 313 on the inlet seat 3 and the quick-release seat A31 and fixed by two sets of bolts.

[0030] like Figure 4 , Figure 5 and Figure 6 As shown: The bottom of the filter cartridge 319 is provided with a conical buffer cone 3192. The conical structure of the buffer cone 3192 at the bottom of the filter cartridge 319 can buffer and guide the airflow during the gas flow process. When the airflow impacts the buffer cone, the conical surface can disperse the instantaneous impact energy of the gas along the conical surface, avoiding a sudden increase in local pressure. At the same time, when the intelligent control valve body 1 is closed, the buffer cone 3192 can guide the airflow to change direction smoothly, reduce the pressure fluctuation caused by the sudden change in flow velocity, reduce the impact force on the valve core inside the intelligent control valve body 1, and weaken the intensity of the pressure wave in the gas hammer effect like a buffer pad, reduce the vibration and damage to the equipment caused by the gas hammer impact, and ensure the stability and safety of the gas system operation. The docking method between the outlet seat 4 and the quick-install seat B41 is the same as the docking method between the inlet seat 3 and the quick-install seat A31 mentioned above.

[0031] The intelligent control valve body 1 is vertically positioned and assembled between quick-installation seat A31 and quick-installation seat B41 through inlet seat 3 and outlet seat 4. Inlet seat 3 and quick-installation seat A31 are quick-installed through quick-installation groove 311 and quick-installation bar 312, and outlet seat 4 and quick-installation seat B41 are quick-installed through quick-installation groove 311 and quick-installation bar 312.

[0032] Working principle: When using the intelligent control valve body 1, during actual installation, hold the intelligent control valve body 1 and position it between quick-installation seats A31 and B41 using a vertical insertion method. During the quick installation process, two sets of quick-installation slots 311 and quick-installation strips 312 can be used for rapid positioning and installation. The vertical insertion method replaces the traditional screw or flange connection method. The guiding design of quick-installation slots 311 and quick-installation strips 312 can achieve alignment and insertion without repeatedly adjusting the bolt hole position or flange alignment, which greatly shortens the installation time. Eliminating the flange connection step makes it especially suitable for confined spaces or high-altitude operations. When disassembling the intelligent control valve body 1 on the pipeline, simply remove the lock seat 315 and the bolts used to fix the quick-release groove 311 and quick-release strip 312. Then, the intelligent control valve body 1 can be disassembled on the pipeline by pulling upwards, avoiding valve body cracks and pipeline deformation during valve disassembly. After the inlet seat 3 and quick-release seat A31 are connected, they can be sealed through the sealing port 313, sealing gasket 314, and lock seat 315 to prevent leakage at the connection.
