Electromagnetic valve block for controlling amount of switched air in multi-level speed-adjusting manner

Abstract

The present invention relates to an electromagnetic valve block for controlling amount of switched air in a multiple-level speed-adjusting manner. The valve block integrates a plurality of electromagnetic valves through setting an air accumulation valve block and a working valve block to realize different air inflow and air outflow, achieving the purpose of multi-level speed adjusting. Specifically, through arranging exhaust connectors with different hole diameters on the air accumulation valve block, the electromagnetic valve block limits the air outflow to control air inflow in a feedback manner so that the valve body assembly still maintains pressure in a case of existence of trace flow to enable a valve core to work normally. The electromagnetic valve block divides the electromagnetic valves into a plurality of groups through the working valve block, each electromagnetic valve being capable of performing independent control, and therefore, the electromagnetic valve block can drive a plurality of pressure-bearing components, such as, a cylinder, so as to enable each pressure-bearing component to realize combined motion with the purposes of independent operation, synchronous operation, asynchronous operation with different speed, asynchronous operation with identical speed and alternating forward and reverse operation.

Description

technical field [0001] The invention relates to an electromagnetic valve block, in particular to a multi-section variable speed switching value control electromagnetic valve block. Background technique [0002] At present, the 4D seat in the audio-visual market, that is, the 4D seat that can realize multi-dimensional movement up, down, left, and right, is usually equipped with a cylinder on the seat base, and the cylinder is controlled by a solenoid valve to expand and contract to push the connected seat to move in all directions. swing. [0003] Existing switching solenoid valves used in this direction, although there are many types and complete specifications, all belong to a rated special product. The user selects one of the specifications according to the maximum value of the gas consumption, and the flow rate can only be changed passively according to the gas consumption of the gas consumption components, and cannot be actively controlled; while the other proportional ...

[0003] Existing switching solenoid valves used in this direction, although there are many types and complete specifications, all belong to a rated special product

The user selects one of the specifications according to the maximum value of the gas consumption, and the flow rate can only be changed passively according to the gas consumption of the gas consumption components, and cannot be actively controlled; while the other proportional valve can actively adjust the flow rate in real time, but Belonging to German technology, it is expensive, has a long delivery cycle, and has very high requirements for the cleanliness of the gas supply

During use, the proportional valve is often damaged and unstable due to gas particles and impurities, which makes the user pay a high price, and makes users of public places such as theaters discouraged.

Moreover, proportional valves are controlled by digital and analog signals, which require more complex flow programs and databases as supporting background services.

Generally, the projection staff equipped in ordinary cinemas usually do not have this kind of professional knowledge, and cannot operate and maintain smoothly, which makes it difficult to promote the audio-visual equipment based on this kind of valve.

[0004] Due to the constraints of the bottleneck of components, most of the 4D seats on the market today are based on a single action, or lifting, or reclining, or swinging left and right, all of which are single and one-time actions, and there is no interaction between them. Organic connection, range of motion and speed of motion are the only range and speed set
