Embodiment Construction
[0025] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0026] The vacuum boundary valve controller provided by the present invention is a fluid mechanical automatic control assembly composed of various functional modules, which is used to open and close the connected boundary valve, and automatically control the opening and closing of the boundary valve according to the set liquid level and release time .
[0027] see figure 1 The vacuum boundary valve controller includes a vacuum on-off control module 1 , a lock control module 4 , an atmospheric on-off control module 6 , a drive control module 8 , a single access quantitative module 12 for vacuum delivery, and a liquid level detection and control module 14 .
[0028] Wherein, the vacuum on-off control module 1 cooperates with the atmospheric on-of...

The invention discloses a controller of a vacuum dividing valve. A vacuum on-off control module of the controller is matched with an air on-off control module to form double two-position two-way valves for on-off switching control so as to achieve on-off control on mutual interlocking of the air and a vacuum source. A locking control module is matched with the vacuum on-off control module to lead the vacuum on-off control module to guide fluid to unidirectionally move when the vacuum on-off control module is connected with the vacuum source and to prevent possible fluid reverse out-of-control motion caused by the fact that the vacuum dividing valve is connected into a vacuum main pipe. A driving control module is matched with a liquid level detection and control module which detects the liquid level of a vacuum delivery site collection unit and drives the vacuum on-off control module and the air on-off control module through the driving control module according to the liquid level. A vacuum delivery single access quantitative module is matched with the driving control module to achieve the required vacuum access delivery ratio. The controller of the vacuum dividing valve is advanced in technology, compact and simple in structure, reliable in work and low in manufacture cost.
Description
technical field [0001] The invention relates to a vacuum boundary valve in a vacuum conveying system, in particular to a controller of the vacuum boundary valve. Background technique [0002] In today's world construction and rapid economic growth, the protection of the ecological environment and pollution control have increasingly become development issues of concern to all walks of life. The daily discharge and treatment technology of wastewater and sewage in living communities and industrial parks is the main way to control pollution and protect the environment. Wastewater and sewage discharge and transportation usually adopt the gravity method, and the vacuum transportation method is an advanced new wastewater and sewage collection and transportation technology that is emerging in developed countries and some developing countries in recent years. [0003] In the vacuum conveying system, the vacuum boundary valve is the key equipment for collection and access, and the co...
