Abstract
The utility model provides a butterfly valve locking device. The butterfly valve locking device at least comprises a box body, a box cover and a lock, wherein the box body is cuboid; one side edge of the box cover is connected with a side wall A of the box body; the box cover covers on an opening of the box body and can rotate around the box body by a hinge; the lock is arranged at the connecting position between the box body and the box cover, and can fix the box cover on the box body; a side wall B and a side wall C, which are adjacent to the side wall A, are respectively provided with an installing groove which extends downwards from the opening position of the box body; the installing grooves on the side wall B and the side wall C are parallel mutually and the positions of the installing grooves correspond mutually; and the box cover is provided with a sliding groove which is vertical to the side wall A. The butterfly valve locking device provided by the utility model has the advantages that the structure is simple, the convenient and practical effects are achieved, and a butterfly valve can be effectively locked.
Description
Technical field
The utility model relates to a kind of locking device, the locking device on particularly a kind of butterfly valve that is applied in the important pipe-line system.
Background technique
Butterfly valve has advantages such as keying is easy, opening travel weak point, good airproof performance, therefore is widely used in the various pipe-line systems, especially in industry fields such as chemical industry, smelting, pharmacy, wine brewing, is seen everywhere especially.The keying of butterfly valve is controlled by valve rod, along with the turn valve rod, can realize that the unlatching of butterfly valve is perhaps closed.In use, owing to some artificial factors, butterfly valve is opened by mistake to open or closes by mistake through regular meeting, and the reason that causes this phenomenon is various, and for example the operator is when walking, and the instrument that shank or its carry has been run into valve rod; Or some unskilled operators' faulty operation; Even also having some malicious sabotages, these all can cause above result.Butterfly valve is opened by mistake, and to open or close the consequence that is caused be very serious, particularly in some important pipelines, tends to produce unthinkable disastrous effect.Therefore, how the butterfly valve on some important pipelines being locked, avoid opening by mistake and open or close, is a problem that needs to be resolved hurrily.
Summary of the invention
The utility model provides a kind of butterfly valve locking device, has solved the problem in the above-mentioned background technology, and it is simple in structure, with low cost, can effectively lock butterfly valve.
Realize that the technological scheme that the utility model above-mentioned purpose is adopted is:
A kind of butterfly valve locking device comprises box body, lid and lock at least, and it is rectangular-shaped that box body is, and a side of lid is connected with the sidewall A of box body through hinge, and lid is covered on the opening of box body and can rotates around box body through hinge; Lock is installed on the joint of box body and lid and can lid be fixed on the box body; Sidewall B adjacent with sidewall A and sidewall C go up and are extended with mounting groove downwards by the box opening place; Mounting groove on sidewall B and the sidewall C be parallel to each other and the position corresponding each other; Lid is provided with chute, and chute is vertical with sidewall A.
Described mounting groove is positioned at the middle part of sidewall B and sidewall C.
The butterfly valve locking device that the utility model provides has following advantage: 1, simple in structure, this device only is made up of box body, lid and a lock, so its manufacture cost is very cheap.2, convenient and practical, in use, pipeline is snapped in the mounting groove, butterfly valve is coated in the box body, and valve rod is locked lid and box body with lock by stretching out in the chute then.Because the keying of butterfly valve is to realize through flat the revolving of valve rod; And valve rod is positioned at chute at this moment, and chute is vertical with the pipeline direction, so valve rod is restricted at this moment can't put down in the chute and revolves; Thereby can't realize the unlatching of butterfly valve or close, come butterfly valve is locked with this.
Description of drawings
The structural representation of the butterfly valve locking device that Fig. 1 provides for the utility model;
The working state schematic representation of the butterfly valve locking device that Fig. 2 provides for the utility model;
Among the figure: 1-lid, 2-hinge, 3-chute, 4-box body, 5-sidewall A, 6-sidewall B, 7-sidewall C, 8-lock, 9-mounting groove, 10-container, 11-pipeline, 12-valve rod.
Embodiment
The structure of the butterfly valve locking device that the utility model provides is as shown in Figure 1; Comprise box body 4, lid 1 and lock 8; Box body 4 is rectangular-shaped, and lid 1 is covered on the opening of box body 4, and a side of lid 1 is connected with the sidewall A5 of box body 4 through hinge; And can rotate around box body 4 through hinge, hinge is a hinge 2 in the present embodiment.Lock 8 is installed on the joint of box body 4 and lid 1 and can lid 1 be fixed on the box body 4.Be equipped with mounting groove 9 on sidewall B6 adjacent and the sidewall C7 on the box body 4 with sidewall A5, mounting groove 9 by box body 4 openings to extending below, the mounting groove 9 on sidewall B6 and the sidewall C7 be parallel to each other and the position corresponding each other, all be positioned at the middle part of sidewall B6 and sidewall C7.Lid 1 is provided with chute 3, and chute 3 is vertical with sidewall A5.
The working state of the butterfly valve locking device that the utility model provides is as shown in Figure 2, and working state shown in this figure is merely a kind of in the numerous user modes of this locking device.Therefore in the present embodiment, butterfly valve is installed on the outlet port of container 10, is contained with combustible material in the container 10, if butterfly valve is opened by mistake and opens and cause that material leaks in the container, consequence is with hardly imaginable.The box body of the butterfly valve locking device that the utility model provides covers on the butterfly valve, and the pipeline 11 of butterfly valve both sides all is snapped in the mounting groove 9, and butterfly valve is coated in the box body, stretches out in the chute 3 of valve rod 12 by lid 1.After with lock 8 lid 1 and box body 4 being locked; Because the keying of butterfly valve is to realize through flat the revolving of valve rod 12; And valve rod is positioned at chute 3 12 this moments, and chute 3 is vertical with pipeline 11 directions, and is as shown in Figure 2; Therefore valve rod is restricted to can't put down in the chute 3 and revolves for 12 this moment, thereby can't realize the unlatching of butterfly valve or close.
