Abstract
The invention belongs to the technical field of valves and relates to the improving process and technology of gate valves, in particular to a gate valve structure with an emergency open function and an implementation method. The problem of pipeline blockage caused by falling of a gate plate of a gate valve can be solved through the gate valve structure and the implementation method under the circumstance that the gate valve for a pipeline does not need to be replaced, and normal circulation of media in the pipeline is guaranteed. Compared with the prior art, the gate valve structure and the implementation method have the advantages that the problem of pipeline blockage caused by falling of the gate plate of the gate valve can be solved under the circumstance that the gate valve for the pipeline does not need to be replaced, normal circulation of the media in the pipeline is guaranteed, the gate valve is not limited to heating pipelines any longer, and general promotional value of other gate valves for pipelines with media is achieved; the problem that during heating in the north, once the gate plate of the gate valve falls off, the gate valve for the pipeline needs replacing and heating must be stopped is solved, influences on heating for residents and enterprise and public institutions are reduced, labor intensity of workers is relieved, the replacement cost of the gate valve is saved, and work efficiency is improved; the structure is simple, implementation is easy, and operation is convenient.
Description
Technical field
The invention belongs to valve technology field, relate to improving technique and the technology of gate valve, especially relate to a kind of gate valve structure with emergency opening function and implementation method.
Background technique
Gate valve is widely used in the pipeline connection of industrial and agricultural production and common people's daily life, is that pipeline connects one of conventional component of conveying flowing medium.Because fed sheet of a media is as water mitigation, add and accumulate over a long period, gate valve is easily caused to get rusty inefficacy, not easily open or close, especially during northern China heat supply in winter, owing to often containing impurity in heating water source, and it is uneven in temperature, in heat, under the long immersion corrosion of cold water source, gate valve in hot duct is usually by corrosion, gate valve plate is caused to come off time serious, valve is caused to open or close, particularly when heating, occur that valve invalidation causes heating water to reveal and causes road surface large size to be frozen, the phenomenon of heating is stopped to happen occasionally, very big inconvenience is brought to the safety of people and normal life.Once there is this situation, need to change valve, just must stop heating, not only affect the normal heating of resident and enterprise, and the weather is cold and the ground is frozen, workpeople changes the difficulty of valve and workload is well imagined, inefficiency, time-consuming effort.
Summary of the invention
For overcoming the deficiencies in the prior art, the invention provides a kind of gate valve structure with emergency opening function and implementation method, this gate valve structure and implementation method can realize when not needing to change pipeline gate valve, solve because flashboard for sluice valve comes off the pipeline blockage problem caused, ensure the normal circulation of pipeline medium.
For achieving the above object, the present invention is achieved through the following technical solutions:
A kind of gate valve structure with emergency opening function, comprise handwheel, valve gap, valve rod, valve body, flashboard, lubricating cup, sleeve pipe, leading screw push rod, standby cap, plug, stuffing box packing, it is characterized in that, described handwheel, valve gap, valve rod, valve body and flashboard form the main body of gate valve, its linkage structure and mode the same with common gate valve; Described sleeve pipe one end is connected with valve body, and the other end is connected with standby cap, and sleeve pipe middle and upper part is provided with lubricating cup; Described leading screw push rod one end is connected to stretch in valve body with valve body by screw thread and props up flashboard, and the other end passes from plug, standby cap; Described plug, between standby cap, sleeve pipe, forms seal space with cannula cavity and the leading screw push rod shaft shoulder, is installed in stuffing box packing.
Described leading screw push rod surface is provided with groove.
Realize a kind of method with emergency opening function gate valve structure, it is characterized in that, improve gate valve technique and structure, leading screw push rod is installed additional in the design of common gate valve body bottom, once there is the urgency that gate valve inefficacy flashboard comes off, utilize lever principle, by the motion of leading screw push rod, the flashboard for sluice valve jack-up that can promptly will come off in hot duct, thus ensure that pipeline medium is unimpeded.
Compared with prior art, the invention has the beneficial effects as follows:
1) can realize when not needing to change pipeline gate valve, solve because flashboard for sluice valve comes off the pipeline blockage problem caused, ensure the normal circulation of pipeline medium, be not only confined to hot duct gate valve, to the pipeline gate valve of other medium, there is general promotional value equally;
2) to solve between northern heating period once flashboard for sluice valve comes off need change pipeline gate valve and must stop heating problem, decrease the impact on resident and enterprises and institutions' heating, reduce labor strength, saved replacing gate valve cost, increased work efficiency;
3) structure is simple, is easy to realize, convenient operation.

Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further:
See Fig. 1, Fig. 2, a kind of gate valve structure with emergency opening function, comprise handwheel 1, valve gap 2, valve rod 3, valve body 4, flashboard 5, lubricating cup 6, sleeve pipe 7, leading screw push rod 8, standby cap 9, plug 10, stuffing box packing 11, it is characterized in that, described handwheel 1, valve gap 2, valve rod 3, valve body 4 and flashboard 5 form the main body of gate valve, its linkage structure and mode the same with common gate valve, using method is too; One end of described sleeve pipe 7 is connected with valve body 4, and the other end is connected with standby cap 9, and the middle and upper part of sleeve pipe 7 is provided with lubricating cup 6, can realize regularly to grease up in sleeve pipe 7 to lubricate leading screw push rod 8 and to prevent its corrosion; One end of described leading screw push rod 8 is connected to stretch in valve body 4 with valve body 4 by screw thread and props up flashboard 5, and the other end passes from plug 10, standby cap 9; Described plug 10, between standby cap 9, sleeve pipe 7, forms seal space with sleeve pipe 7 inner chamber and leading screw push rod 8 shaft shoulder, is installed in stuffing box packing 11, prevents from revealing.
See Fig. 3, Fig. 4, described leading screw push rod 8 surface is provided with groove 81 and holds lubricating grease, guarantees that leading screw push rod 8 fully contacts with lubricating grease, lubricates and prevents leading screw push rod 8 corrosion.
Realize a kind of method with emergency opening function gate valve structure, it is characterized in that, improve gate valve technique and structure, leading screw push rod 8 is installed additional in the design of common gate valve body 4 bottom, once occur the urgency that gate valve inefficacy flashboard 5 comes off, utilize lever principle, to be turned clockwise leading screw push rod 8 by spanner, the flashboard 5 that leading screw push rod 8 promotes to have come off rises gradually, flashboard for sluice valve 5 jack-up that just can promptly will come off in hot duct, thus ensure that pipeline medium normally circulates, valve is changed again in time stopping heating, avoid the misery that bad valve is had to change in the world of ice and snow.
