Abstract
The utility model relates to a valve device that is used for valve electric control, loses the electricity and opens fast and take cushioning effect. The device comprises an electric device, a connecting rod, a connecting frame, an electromagnet, a heavy hammer device and a buffer cylinder. The method is characterized in that: under a normal state, the electric device drives the connecting rod to drive the electromagnet to attract the heavy hammer device to be connected with the valve rod to adjust the opening of the butterfly plate; under emergency, the electro-magnet loses the electricity and breaks away from with the weight subassembly, and the weight whereabouts, the valve is promptly opened, and tail state, buffer cylinder slow down weight impact velocity, avoid causing the harm to the valve rod. The utility model discloses drive arrangement both adjustable valve flow, accessible electro-magnet loses the electricity and promptly opens and rely on buffer to reduce the impact again, and easy operation is reliable.
Description
Technical Field
The utility model relates to a valve device that is used for valve electric control, loses the electricity and opens fast and take cushioning effect specifically is an electronic quick buffer that opens with electromagnetic type regulation.
Technical Field
At present, most of quick opening devices are controlled electrically, pneumatically or hydraulically, once the electric control is powered off, the electric control is not controlled, an additional control system is added for hydraulic or pneumatic control, and the cost is high. The electromagnetic quick-opening valve can not be adjusted by using electromagnetism alone, and can cause great impact on a valve rod when being opened, so that the service life of the valve is shortened.
SUMMERY OF THE UTILITY MODEL
The invention aims to provide a novel electric and electromagnetic adjusting quick-opening buffer device, which can play the role of adjusting a valve and also play the role of quick opening under the emergency state or power failure condition, and can form buffering by the characteristics of a cylinder, thereby reducing the damage to the valve.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
an electric and electromagnetic type adjusting quick-opening buffer device comprises an electric device, a connecting rod, a connecting frame, an electromagnet, a heavy hammer assembly, a buffer cylinder, a pin shaft, a valve rod and a positioning sleeve;
the electric device is connected with the connecting rod through a pin shaft, the connecting rod is connected with the connecting frame through the pin shaft, the connecting frame is connected with the heavy hammer component through the electromagnet, the heavy hammer component is connected with the valve rod through a flat key, a positioning sleeve is sleeved outside the valve rod, the lower end of the connecting frame is fixed on the positioning sleeve, the axial displacement of the connecting frame is limited by the positioning sleeve, and the lower part of the heavy hammer component is connected with the buffer cylinder.
The utility model discloses a theory of operation and process are: electric actuator (1) drives electro-magnet (4) and weight subassembly (5) governing valve door opening, and electro-magnet (4) lose the electricity, and weight subassembly (5) whereabouts make the valve open fast, and buffer cylinder (7) then cushion valve rod (8) strike.
When the electric device works, the electric device (1) drives the electromagnet (4) and the heavy hammer component (5) to drive the valve rod (8) to rotate. When the electromagnet (4) loses power, the heavy hammer component (5) falls, the valve is quickly opened, and the electric device (1) is separated from the valve rod (8). When the valve is opened to 90 degrees quickly, the buffer cylinder (7) buffers the valve rod (8) and buffers the impact of the valve rod.
The utility model adopts the above scheme beneficial effect who produces does:
1. adopt electronic with electromagnetic type regulation buffer that opens soon, realize valve regulatory function through adjusting electric actuator.
2. The utility model discloses a power supply is done to electric power and gravity, relies on the action of gravity to open the valve fast when the electromagnetism loses the electricity.
3. The utility model discloses a buffer cylinder utilizes the characteristics of cylinder itself, makes air compression form pressure gradually, alleviates weight impact velocity, reaches the purpose of protection valve rod.
The utility model discloses the product both can play adjusting valve's effect, can play the effect of opening soon again under emergency or outage condition, and form the buffering with the characteristics of cylinder itself, can reduce the harm to the valve. At present, no similar products exist in the industry, and the blank of domestic products of the same type is filled.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
As shown in the attached drawings 1 and 2, the utility model relates to an electronic with electromagnetic type regulation buffer that opens soon, it includes electric actuator 1, connecting rod 2, link 3, electro-magnet 4, weight subassembly 5, cushion cylinder 7, round pin axle 6 in addition, 10, 11, valve rod 8, position sleeve 9 etc.. Electric actuator 1 is connected with connecting rod 2 through a round pin axle 11, connecting rod 2 is connected with link 3 through round pin axle 10, link 3 is connected with weight subassembly 5 through electro-magnet 4, weight subassembly 5 is connected through the parallel key with valve rod 8, 8 overcoat of valve rod are equipped with position sleeve 9, the lower extreme of link 3 is fixed on position sleeve 9, position sleeve 9 prescribes a limit to link 3 axial displacement, weight subassembly 5 lower part is connected with the piston rod of cushion cylinder 7 through round pin axle 6
As shown in fig. 3, when the electromagnet 4 is powered on, the electric device 1 drives the connecting frame 4 and the heavy hammer assembly 5 to drive the valve rod 8 to make a rotary motion through the connecting rod 2, and the buffer cylinder 7 does not generate a pressure difference in the slow moving process and does not form resistance on the electric device 1.
As shown in fig. 4, when the valve is in a closed state, once the electromagnet 4 loses magnetism and is separated from the weight assembly 5, the connecting frame 3 is connected with the valve rod 8 by an optical axis, the device 1 cannot be driven to operate, and the weight assembly 5 rapidly falls due to the action of gravity, so that the valve is opened. The gas in the buffer cylinder 7 is compressed quickly and cannot be released in time to form pressure, so that the falling speed of the heavy hammer component 5 is reduced, and the impact on the valve is reduced.
