Portable valve operation device

Abstract

The invention relates to a portable valve operation device which is characterized by comprising a power source, a power source transmission mechanism, a connector and a hand wheel connecting chuck, wherein the power source is connected with the power transmission mechanism through the connector; the connector is connected with the power source; the output end of the power transmission mechanism is bonded with a central hole in the hand wheel connecting chuck; a plurality of grousers are screwed with the plane of the hand wheel connecting chuck so as to form a hand wheel locking mechanism. The portable valve operation device has the beneficial effects that the tool is simple in structure, convenient to carry, small in size and simple and convenient to operate, the safety coefficient of valve operation can be increased, the valve operation efficiency can be improved, operation of multiple tube diameters and multiple types of valves can be achieved, and operation on valves in multiple directions can be also achieved. Operation danger site sources can be reduced, the working safety can be improved, the time for opening and closing the valves can be shortened, the working efficiency can be improved, and opening and closing of multiple types of valves can be achieved.

Description

technical field [0001] The invention belongs to valve tools, in particular to a portable valve operating device for valves. Background technique [0002] Valves are widely used in various industries, mainly petroleum, petrochemical, chemical, environmental protection, metallurgy, electric power, water conservancy, urban construction, fire protection, coal, food and others. Among them, users in the environmental protection and chemical industries are most concerned about the valve market and have higher requirements for valves. In the current market, butterfly valves, ball valves, etc. are the most widely used and most common types of valves in the valve user industry. [0003] With the widespread promotion of recycled water utilization, most recycled water plants consider the overall layout beautiful. In the reclaimed water plant, the membrane filtration storage tank, ozone contact tank, clean water tank and water delivery pump room are designed in underground or semi-unde...

AI Technical Summary

Problems solved by technology

In the actual production process, manual control valves, especially large valves with a diameter exceeding DN600, will have the following problems during manual operation: First, the size of the hand wheel is large, and there are certain difficulties in manual operation, and most large valves are secondary Variable speed or multi-stage variable speed, the overall operation is time-consuming and laborious. For example, it takes at least 2 hours to manually open or close the valve of DN1600, and multiple people need to operate in rotation; second, due to the constraints of the site conditions, the working space is small; third, Most valves are installed underground or semi-underground, even underground, and the harsh environment in the underground increases the risk of valve operation
