Abstract
The utility model discloses a valve locking device, which comprises a cap (1), connecting plates (2) and an opening device. A cavity is formed in the cap (1). The connecting plates (2) are arranged on the sides of the cavity wall of the cap (1). The opening device is arranged at the lower ends of the connecting plates (2). Therefore, cost is decreased, and valve locking reliability is improved.
Description
One, technical field
The utility model relates to a kind of valve locking apparatus, and especially a kind of adaptation is used for the valve locking apparatus on the heat supply pipeline.
Two, background technique
In daily life and producing, we need use pipeline to carry liquid such as gas and water, in order to keep the unimpeded of conveyance conduit and to end; Need be on pipeline mounted valve, so valve is an important industry equipment, in existing valve; Though the locking valve is arranged, and cost is higher, be common valve for what also just install in some original pipelines especially; For needs, also device can not carry out locking to valve.
Three, summary of the invention
In order to overcome above-mentioned technical disadvantages, the purpose of the utility model provides a kind of valve locking apparatus, has therefore reduced cost, has improved the reliability of valve locking.
For achieving the above object, the technological scheme that the utility model is taked is: include block, connecting plate and opening device, in block, be provided with cavity, connecting plate is arranged on the cavity wall side of block, is provided with opening device in the lower end of connecting plate.
To valve, the handle of valve is placed in the inner chamber of block, reaches connecting plate the downside of pipeline; Re-use opening device and fix connecting plate, owing to designed block, connecting plate and opening device, valve handle is linked together through connecting plate and opening device and pipeline; When making opening device be in abnormal working position; Valve handle just can not rotate, and has therefore reduced cost, has improved the reliability of valve locking.
The utility model has designed, and the cross section of block is set to U-shaped.
The utility model has designed, and connecting plate is set to two and be set to connect with the hinge of blocking a shot.
The utility model has designed; Opening device is set to include inserted link and lockset, is provided with corresponding jack in the lower end of connecting plate, and inserted link is arranged in the jack; Be provided with protuberance and be set at an end of inserted link and connect, be provided with lockset at the other end of inserted link with the connecting plate contact-type.
Four, description of drawings
Accompanying drawing is the schematic representation of the utility model.
Five, embodiment
Accompanying drawing is an embodiment of the utility model; Specify present embodiment in conjunction with accompanying drawing, include block 1, connecting plate 2, inserted link 3 and lockset 4, in block 1, be provided with cavity; Connecting plate 2 is arranged on the both sides of the cavity wall of block 1; Connecting plate 2 is set to connect with 1 hinge of blocking a shot, and is provided with corresponding jack in the lower end of connecting plate 2, and inserted link 3 is arranged in the jack; Be provided with protuberance and be set at an end of inserted link 3 and connect, be provided with lockset 4 at the other end of inserted link 3 with connecting plate 2 contact-types.
In the present embodiment, the cross section of block 1 is set to U-shaped.
For a certain road pipeline is ended; Need valve close by the time; Prevent other staff's unlatching blindly, to valve, the handle of valve is placed in the inner chamber of block 1; Reach the downside of pipeline to connecting plate 2, re-use inserted link 3 and link together the connecting plate 2 of both sides with lockset 4.
My company is a tame heat supply unit, and is annual because the unauthorised opening of valve has been wasted many heats, through the enforcement of the utility model, guaranteed the safety of ending of some valve, reduced scattering and disappearing of heat, for company has created economic benefit.
The characteristics of the utlity model has down:
1, owing to designed block 1, connecting plate 2 and opening device; Valve handle is linked together through connecting plate 2 and opening device and pipeline, and when making opening device be in abnormal working position, valve handle just can not rotate; Therefore reduce cost, improved the reliability of valve locking.
2, owing to designed connecting plate 2, connecting plate 2 is directly contacted with pipeline, whole device and pipeline are linked together, prevented that improper property is to blocking a shot 1 unlatching.
3, owing to designed inserted link 3 and lockset 4, simple to operate, it is convenient to open.
In valve locking apparatus technical field; Be provided with cavity in 1 every including at block, and connecting plate 2 is arranged on the cavity wall side of block 1, and the technology contents that is provided with opening device in the lower end of connecting plate 2 is all in the protection domain at the utility model.
