This fixing device transports fixedly to the extension bar ball valve after pulling down actuating mechanism, and the installation is swift, and fixed mode is reliable, ensures that extension bar can not fall away from the assembly position in the transportation again to avoid the repair that causes in the product transportation, reduce the loss of manpower, material resources.
Description
Technical Field
The utility model relates to a ball valve conveyer technical field especially relates to a valve rod fixing device in extension bar ball valve.
Background
In a factory, as shown in fig. 1, after the extension bar ball valve with the automatic actuating mechanism is debugged, the actuating mechanism is removed, and the valve part and the actuating mechanism part are packaged and transported separately because the height of the extension bar ball valve far exceeds the specified transportation height. When the actuator is removed, the elongated stem of the valve portion is free of the retaining fixture, as shown in FIG. 2. In order to ensure that the assembly position of the extension valve rod does not change during packaging and transportation, a wooden wedge 3 is usually plugged into a gap between the extension valve rod 1 and the extension outer rod 2 during packaging, and an iron wire 4 is used for tightly fixing the exposed outer round head of the extension valve rod on a flange of the extension outer rod 2. Due to jolting in the long-distance transportation process, the wood wedge is easy to drop and break, and the iron wire is easy to break, so that the lengthened valve rod falls away from the assembly position, the product is repaired, and the loss of manpower and material resources is brought.
SUMMERY OF THE UTILITY MODEL
In order to overcome the technical defect who exists, the utility model aims to provide an installation is swift, and fixed mode is reliable, ensures that the extension valve rod can not fall from the mounted position in the transportation again to avoid the reprocessing that causes in the product transportation, reduce the extension bar ball valve in valve rod fixing device of the loss of manpower, material resources.
In order to achieve the above purpose, the utility model discloses a following technical scheme realizes:
the technical scheme is that the valve rod fixing device in the extension rod ball valve comprises a cover cap and a fastening bolt; the middle part of the cover cap is provided with a convex cavity for accommodating the head part of the lengthened valve rod; a plurality of fastening bolts are arranged through the outer wall of the convex cavity on the cap, and the plurality of fastening bolts act on the same plane; the cap covers the head of the lengthened valve rod and is connected with the plane of the flange on the lengthened outer rod.
Further preferably, the cap is provided with screw holes corresponding to the flange unthreaded holes in the lengthened outer rod one to one, and the cap is connected with the lengthened outer rod through a connecting bolt.
Further preferably, the number of the fastening bolts is 3, one fastening bolt is taken as a symmetric center, and the other two fastening bolts are arranged in a left-right symmetric manner.
Further preferably, the upper end of the convex cavity on the cover cap is closed.
The beneficial technical effects are as follows:
this fixing device transports fixedly to the extension bar ball valve after pulling down actuating mechanism, and the installation is swift, and fixed mode is reliable, ensures that extension bar can not fall away from the assembly position in the transportation again to avoid the repair that causes in the product transportation, reduce the loss of manpower, material resources. The upper end of the protruding cavity on the cover cap is sealed, so that impurities are prevented from entering a gap between the lengthened valve rod and the lengthened outer rod in the transportation process, and influence on subsequent assembly and use of the valve is avoided.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Embodiment, as shown in fig. 5 and 6, the utility model relates to a valve rod fixing device in an extension rod ball valve, which comprises a cover cap 5 and a fastening bolt 6; a convex cavity for accommodating the head of the lengthened valve rod 1 is arranged in the middle of the cap 5; a plurality of fastening bolts 6 are arranged through the outer wall of the convex cavity on the cap, and the plurality of fastening bolts 6 act on the same plane; the cap 5 covers the head of the lengthened valve rod 1 and is connected with the upper flange plane of the lengthened outer rod 2.
The nut cap 5 is provided with screw holes which are in one-to-one correspondence with the flange unthreaded holes on the lengthened outer rod 2, and the nut cap 5 is connected with the lengthened outer rod 2 through a connecting bolt 7.
As shown in fig. 6, the number of the fastening bolts 6 is 3, and with one of the fastening bolts as a symmetry center, the other two fastening bolts are arranged in bilateral symmetry.
