Abstract
A device for keeping a ball valve in a fully-opened state is composed of two half steel pipe supports, a hinge for combining the two half steel pipe supports, a jacking bracket made of half flange plates arranged at two ends of the two half steel pipe supports, a door nose component for buckling the two half steel pipe supports, and a locking bolt. During the use, open the ball valve to full open mode, the pneumatic cylinder piston rod stretches out completely, presss from both sides the device on the piston rod, and it is inseparable that the device will close with the bolt insertion door nose component after, and both ends top is held in the palm the upper end that supports the piston rod respectively and the top of piston cylinder, prevents the piston rod withdrawal, has effectively guaranteed that the ball valve is not closed at full open mode.
Description
Technical Field
The utility model relates to a power station overhauls isolated plant, concretely relates to make ball valve keep device of full open state.
Background
The pressure steel pipe detection is a project which is necessary to be done after the pumped storage power station is put into operation for 10 years, the ball valve needs to be kept in a reliable full-open state when the pressure steel pipe detection is carried out, the ball valve is used as a personnel channel, but the driving part of the hydraulic control water turbine water inlet ball valve is a crank arm connected with a hydraulic servomotor, the driving part is used for driving the ball valve to open and close, and the ball valve has the self-closing characteristic, so that when the pressure steel pipe detection is carried out, the problem that how to keep the ball valve in the reliable full-open state but not close is difficult is solved.
Disclosure of Invention
The utility model aims to solve the technical problem that overcome above-mentioned prior art not enough, and provide a low cost, simple structure, convenient to use's messenger's ball valve keeps the device of full open state.
The utility model provides a technical scheme that its technical problem adopted does: a device for keeping a ball valve in a fully-opened state is composed of two half steel pipe supports, a hinge for combining the two half steel pipe supports, a jacking bracket made of half flange plates arranged at two ends of the two half steel pipe supports, a door nose component for buckling the two half steel pipe supports, and a locking bolt. During the use, open the ball valve to full open mode, the pneumatic cylinder piston rod stretches out completely, presss from both sides the device on the piston rod, and it is inseparable that the device will close with locking bolt insert door nose component after, and both ends top support supports the upper end and the top of piston cylinder that support the piston rod respectively, prevents the piston rod withdrawal, has effectively guaranteed that the ball valve is not closed at full open mode, for the long-term use of guaranteeing the device, and steel pipe supporting material is preferably the stainless steel.
The utility model provides a this kind of make ball valve keep device of full open state, low cost, simple structure, convenient to use, two half steel pipe supports that it contains and half ring flanges in both ends can change different pipe diameters according to the size of piston rod, and the special pipe is special to showing and improving maintenance efficiency, having guaranteed production safety more.

Fig. 1 is a schematic rear structural view of a device for keeping a ball valve fully open according to an embodiment of the present invention;
fig. 2 is a schematic side structural view of a device for keeping a ball valve in a fully open state according to an embodiment of the present invention;
the labels in the figure are: 1. steel pipe support, 2, hinge, 3, top support, 4, door nose component, 5, locking bolt.
Detailed Description
The present invention will be further clarified by the following description with reference to the attached drawings and examples, which should be understood as the examples only for illustrating the present invention and not for limiting the scope of the present invention, and after reading the present invention, the modifications of the various equivalent forms of the present invention by those skilled in the art all belong to the scope defined in the present application.
Referring to the attached drawing 1, the embodiment of the utility model provides a low cost, simple structure, convenient to use's messenger ball valve keeps device of full open state, it by two half steel pipe support 1, be used for making two half steel pipe support hinge 2 together, two half steel pipe support the top that half ring flange that both ends set up was made hold in the palm 3, be used for two half steel pipe to support to detain the door nose component 4 and the locking bolt 5 that closes mutually and constitute. During the use, open the ball valve to full open mode, the pneumatic cylinder piston rod stretches out completely, presss from both sides the device on the piston rod, and the back inserts door nose component 4 with locking bolt 5 and closes the device closely, and both ends top support 3 supports the upper end of piston rod and the top of piston cylinder respectively, prevents the piston rod withdrawal, has effectively guaranteed that the ball valve is not closed at full open mode, and in order to guarantee the long-term use of device, the steel pipe supports 1 material preferred stainless steel.
