(2) The utility model discloses be connected ratchet spanner with the extension arm of force, increased the moment of torsion to safe in utilization, single can work for a long time in succession, greatly promoted personnel work efficiency.
(3) The utility model provides a built-in three-jaw of hand wheel is triangle-shaped, has better stability, and high pressure measurement station valve switch in-process hand wheel is built-in three-jaw not fragile.
(4) The utility model adopts the combined design and consists of three detachable components, therefore, the storage component and the installation component of the utility model are both convenient; in addition, the built-in three-jaw of hand wheel can be placed in the valve inboard for a long time, and ratchet spanner also can keep connected state with the extension arm of force for a long time, and then only need connect ratchet spanner and the built-in three-jaw of hand wheel when staff's switching valve, can realize quick switch valve, and work efficiency is higher.
Drawings
FIG. 1 is a schematic structural view of a special wrench for a high-pressure measuring point blowdown valve and a primary valve;
description of the reference numerals: the ratchet wrench comprises a lengthened force arm 1, a ratchet wrench 2, a positive and negative shifting piece 21, a quick release button 22, a buckle 23, a hand wheel built-in three-jaw 3, a steel plate 31, a screw 32 and a connecting piece 33.
Detailed Description
The present invention will be further described with reference to the following examples. The following description of the embodiments is merely provided to aid in understanding the invention. It should be noted that, for those skilled in the art, the present invention can be modified in several ways without departing from the principle of the present invention, and these modifications and modifications also fall into the protection scope of the claims of the present invention.
Example 1:
the valve is a device commonly used in power plants, such as a high pressure station blow-down valve or a primary valve, and is operated by a hand wheel. For example, a clockwise rotation direction of the hand wheel is defined as a closing direction, and a counterclockwise rotation direction of the hand wheel is defined as an opening direction.
In the prior art, the valve is usually operated by using an F-shaped wrench, but because the force application point of a hand wheel is single, the wrench and the hand wheel of the valve are not easy to clamp firmly during operation, and the wrench is easy to slide off.
In order to solve the difficult firm problem of card between spanner and the hand wheel, this application provides a special spanner of high pressure measurement station blowoff valve and primary valve, as shown in figure 1, include: the lengthened force arm 1, the ratchet wrench 2 and the hand wheel are internally provided with three claws 3; the lengthened force arm 1, the ratchet wrench 2 and the hand wheel built-in three claws 3 are connected in sequence;
the ratchet wrench 2 comprises a ratchet wrench handle and a ratchet wrench head, the ratchet wrench handle is connected with one end of the lengthened force arm 1, the ratchet wrench head is provided with a forward-reverse shifting piece 21, a quick release button 22 and a buckle 23, and the ratchet wrench head is connected with the hand wheel built-in three-jaw 3 through the buckle 23. Illustratively, ratchet wrench 2 is a 72 tooth large fly ratchet wrench.
The hand wheel built-in three-jaw 3 comprises a steel plate 31, a screw 32 and a connecting piece 33; the steel plate 31 is in an equilateral triangle shape, so that the stability is good, and the three claws 3 arranged in the hand wheel are not easy to damage in the process of opening and closing the high-pressure measuring point valve; the surface of the steel plate 31 facing the switch valve is the front surface; the screw rods 32 are welded at each vertex of the front surface of the steel plate 31; the connecting piece 33 is welded on the back of the steel plate 31; the surface of the hand wheel is internally provided with three claws 3 for painting. Illustratively, the steel plate 31 is a triangular angle steel with the thickness of 6mm, and any side of the triangle is 130mm; the length of the screw 32 is 30mm, and the width is 14mm; the connector 33 is a 24mm diameter socket head connector. In the use process, the built-in three claws of the hand wheel are tightly attached to the inner side of the valve, so that the force application points are multiple, and the hand wheel is not easy to slide.
The surface of the ratchet wrench head facing the back of the steel plate 31 is the front surface of the ratchet wrench head, the buckle 23 is positioned on the front surface of the ratchet wrench head, and the positive and negative plectrum 21 and the quick release button 22 are positioned on the back surface of the ratchet wrench head.
