Abstract
The utility model relates to a tool for repairing a gate valve, in particular to a special fishing tool for a gate of a gate valve. The special fishing tool comprises a pull rod, wherein a transverse sheet fastened with the gate is arranged at the lower end of the pull rod. The special fishing tool is simple in structure, scientific and reliable in design concept, high in practical value and easy to manufacture.
Description
Technical field
The utility model relates to a kind of instrument that slide valve is used of repairing.
Background technology
Slide valve is one of the most frequently used block valve, is mainly used to connect or block the medium in pipeline, does not apply to regulate rate-of flow.The pressure, temperature and the diameter range that use are very large, in especially applying to, large diameter pipeline.Slide valve for example has many good qualities: its fluid resistance is little, and lock body interior media through hole leads directly to, MEDIA FLOW through the time do not change its flow direction, thereby flow resistance is less; During keying, the flashboard direction of motion and media flow direction are perpendicular, compare with other valves, and its keying is comparatively laborsaving.But slide valve also has weak point, opens and closes for a long time medium and enters space between valve body and valve rod by the gap between flashboard and valve body, the end that corrosion valve rod and flashboard are fastened and connected.During maintenance, flashboard need to be taken out from valve body.Because the end of valve rod is corroded, break away from flashboard, therefore can not get flashboard by valve rod.In existing situation, can only be with pliers with the flashboard gripping.Space in valve body is less, gets with pliers that flashboard is time-consuming, effort.
Summary of the invention
Of the present utility model is exactly for the deficiencies in the prior art, and a kind of instrument for the maintenance slide valve is provided.This tool construction is simple, and is easy to operate, saves time, laborsaving, and cost is low, be easy to make.
The technical scheme that the utility model provides is:
The gate plate of gate valve Special fishing tool comprises pull bar, and the pull bar bottom is provided with the transverse sheet that is interlocked with flashboard.
Concrete, also including baffle plate and nut, pull bar passes the hole on baffle plate, and pull bar is provided with external screw thread, and nut is connected with pull rod screw and is positioned at above baffle plate.
Preferably, nut is provided with handle.
Concrete, living between described pull bar and transverse sheet is connected.
The utility model is simple in structure, and the design concept science is reliable, and practical value is high, saves time, laborsaving, is easy to make.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of described slide valve.
1 valve body 2 valve gap 3 flashboard 4 valve rod 5 pull bar 6 baffle plate 7 nuts
8 handle 9 transverse sheets.
The specific embodiment
As shown in Figure 1, the gate plate of gate valve Special fishing tool comprises pull bar, baffle plate, nut and handle.The pull bar bottom is provided with the transverse sheet that is interlocked with flashboard.Living between described pull bar and transverse sheet is connected, the mode that is threaded as employing.Can according to the size of valve body, select the transverse sheet of different sizes like this.Pull bar passes the hole on baffle plate, and pull bar is provided with external screw thread, and nut is connected with pull rod screw and is positioned at above baffle plate.Be fixed with handle on nut.
After the valve rod end of slide valve the inside is corroded as shown in Figure 2, flashboard can not be pulled out.After shedding valve gap, then transverse sheet and flashboard fastening with the pull bar bottom pass pull bar the hole on baffle plate, will be connected on pull bar with the nut sleeve of handle at last.Rotary handle, nut presses valve body by baffle plate, makes pull bar move upward, and then pulls out flashboard.
If there is no baffle plate and nut, also can fix valve body directly with transverse sheet and the flashboard fastening of pull bar lower end, flashboard is pulled out.
