Problems solved by technology
Except for handwheel drive, other driving methods require an auxiliary system and preconditions; if there is a problem with the auxiliary system or the preconditions are missing, the entire pipeline or equipment controlled by the flat valve will not be able to operate
For some important pipelines or equipment, the inability to operate means major economic losses or safety accidents
The existing solution to ensure operation is usually "dual valve configuration": that is, a manual control valve is connected in series near the automatic control valve; if it is a complex pipeline or equipment, how many automatic control valves are used, it needs to be configured How many manual control valves; this not only increases the volume and weight of pipelines or equipment, but also increases the waste of social resources and the economic burden of users

Embodiment Construction
[0011] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0012] figure 1 Middle: The present invention can be divided into three components: the main body of the flat valve, the handwheel driving mechanism and the hydraulic driving mechanism. The overall structural form is that the upper and lower ends of the main body of the flat valve are respectively equipped with a handwheel driving mechanism and a hydraulic driving mechanism. The main body of the flat valve of the present invention is composed of a valve body (1), a valve seat assembly (2), a gate (3), a gasket ring (4), bolts and nuts (6) and a protective plate (26). In the main body of the plate valve, the valve body (1) is a four-way part with up and down, left and right symmetry, the left and right ends are protruding medium channels and connecting flanges, and the middle is a columnar body; the sides of the left and right connecting flan...

The invention discloses a split hand wheel and hydraulic drive flat valve. The split hand wheel and hydraulic drive flat valve consists of a flat valve body, a hand wheel driving mechanism and a hydraulic driving mechanism. The upper end and the lower end of the flat valve body are fixedly connected with a valve cover in the hand wheel driving mechanism and a valve cylinder cover in the hydraulic driving mechanism by a sealing gasket ring and a bolt / nut. The upper end of a ball screw in the hand wheel driving mechanism is movably connected with a ball nut by a spiral groove, and the lower end is movably connected with an L-shaped groove in the upper end of a middle gate plate of the flat valve body by a groove; and the upper end of a piston rod in the hydraulic driving mechanism is movably connected with a T-shaped groove in the lower end of the middle gate plate of the flat valve body by a groove, and the lower end is inserted in a center hole of a piston block and fixedly connected with the upper end of the guide rod by a thread and a fastening screw. Through necessary part adjustment, the hydraulic or manual drive can be respectively performed for one valve, so that the valve performance is improved, the pipeline or equipment structure is simplified, the normal operation is guaranteed, and the economic benefit and the social benefit are prominent.
Description
technical field [0001] The invention relates to the field of petrochemical industry and the development of new products of flat valves. Background technique [0002] Among the existing petrochemical equipment at home and abroad, the flat valve is driven by a single mode; that is, either handwheel drive, hydraulic drive, motor drive, or pneumatic drive. Except for handwheel drive, other driving methods require an auxiliary system and preconditions; if there is a problem with the auxiliary system or the preconditions are missing, the entire pipeline or equipment controlled by the flat valve will not be able to operate . For some important pipelines or equipment, failure to operate means major economic losses or safety accidents. The existing solution to ensure operation is usually "dual valve configuration": that is, a manual control valve is connected in series near the automatic control valve; if it is a complex pipeline or equipment, how many automatic control valves are ...
