Description

Technical Field

[0001] The utility model relates to the technical field of emergency disposal devices for oil depots, in particular to a quick-opening wrench for fire-fighting butterfly valves. Background Art

[0002] Oil depot fire butterfly valves have the advantages of simple structure, reliable sealing, easy opening, long life, and easy maintenance. They are widely used in oil depot fire protection systems. However, in actual application, when operating a manually operated butterfly valve without an electric actuator, the fire butterfly valve opens and closes too slowly due to the long time it takes to turn the handwheel, which will affect the handling speed in an emergency. Utility Model Content

[0003] The purpose of the utility model is to solve the problem that the oil depot fire butterfly valve in the prior art has the advantages of simple structure, reliable sealing, easy opening, long service life, convenient maintenance, etc., and is widely used in the fire protection system of the oil depot. However, in the actual application process, when operating the manually operated butterfly valve without an electric actuator, the hand wheel is rotated for a long time, resulting in the fire butterfly valve opening and closing speed being too slow, which will affect the handling speed in an emergency state. The proposed fire butterfly valve quick opening wrench

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] The utility model discloses a quick opening wrench for a fire butterfly valve, comprising a plug, wherein the plug is a cylindrical structure, the side wall of the plug is provided with three arc-shaped openings, the upper side wall of the arc-shaped opening is provided with a socket, and the side wall of the plug is fixedly connected with a connecting piece.

[0006] Preferably, the lower side wall of the connecting member is fixedly connected to a connecting seat, the lower side wall of the connecting seat is fixedly connected to a handle, and the lower side wall of the handle is fixedly connected to a frustum.

[0007] Preferably, the connecting piece is a cylindrical structure.

[0008] Preferably, the rear end of the plug is 0.8-1.2 cm, and the inner diameter of the plug is 10 cm.

[0009] Preferably, the length of the connecting piece is 30-50 cm.

[0010] Preferably, the length of the handle is 15-20 cm.

[0011] Preferably, the surfaces of the plug, the connector and the handle are all sprayed with epoxy zinc-rich primer.

[0012] Compared with the prior art, the utility model provides a fire butterfly valve quick opening wrench, which has the following beneficial effects:

[0013] 1. The fire butterfly valve quick opening wrench, through the provided plug, arc-shaped mouth, socket, connector, connection seat, and handle, can insert the plug into the outside of the hand wheel when opening and closing the fire butterfly valve, and then rotate the plug through the handle and the connector to make the plug drive the hand wheel to rotate quickly, so that the fire butterfly valve can be quickly opened and closed within ten seconds.

[0014] 2. The fire butterfly valve quick opening wrench has a cylindrical connecting piece. When the fire butterfly valve has a large rotation resistance, the extension rod can be inserted into the connecting piece to extend the force arm of the plug, thereby facilitating the rotation of the fire butterfly valve.

[0015] Moreover, the parts not involved in the device are the same as the prior art or can be implemented by using the prior art. When opening and closing the fire butterfly valve, the utility model can insert the plug outside the hand wheel, and then rotate the plug through the handle and the connecting piece, so that the plug drives the hand wheel to rotate quickly, and the fire butterfly valve can be quickly opened and closed within ten seconds. When the rotation resistance of the fire butterfly valve is large, the extension rod can be inserted into the connecting piece to extend the force arm of the plug, so as to facilitate the rotation of the fire butterfly valve.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-3 The fire butterfly valve quick opening wrench comprises a plug 1, which is a cylindrical structure. The side wall of the plug 1 is provided with three arc-shaped openings 2, the upper side wall of the arc-shaped openings 2 is provided with a socket 3, and the side wall of the plug 1 is fixedly connected with a connector 4.

[0022] The lower side wall of the connector 4 is fixedly connected to a connector base 5 , the lower side wall of the connector base 5 is fixedly connected to a handle 6 , and the lower side wall of the handle 6 is fixedly connected to a round table 7 , which facilitates the operator to rotate the plug 1 .

[0023] The connecting piece 4 is a cylindrical structure. When the fire butterfly valve has a large rotation resistance, an extension rod can be inserted into the connecting piece to extend the force arm of the plug, thereby facilitating the rotation of the fire butterfly valve.

[0024] The rear end of the plug 1 is 0.8-1.2 cm, and the inner diameter of the plug 1 is 10 cm.
