Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of hydraulic butterfly valve isolation station, and particularly relates to a quick switch tool for hydraulic butterfly valve isolation station. BACKGROUND

[0002] In recent years, with the continuous development of offshore oil and chemical industry, the marine hydraulic butterfly valve is more and more widely used. For the hydraulic butterfly valve in the cabin, pump cabin, ballast tank, cargo oil tank and other cabins on the offshore oil floating production storage and offloading vessel (FPSO), since it works at the bottom of the cabin, the space of the cabin bottom is small, and the valve cannot be quickly repaired after internal leakage or external leakage, so that the valve maintenance is difficult.

[0003] At present, in order to quickly isolate the valve and prevent a large amount of hydraulic oil from leaking into the cabin, the movable wrench or the vice clamp is generally used to clamp the valve ear to switch the valve when the hydraulic butterfly valve isolation station is switched, although the basic switching demand can be met, but in the actual use process, the following problems exist: 1. The movable wrench or the vice clamp is easy to slip when operating; especially for the isolation station with long working time, the threads are seriously corroded, and it is difficult to switch with the ordinary wrench or vice clamp, and if the operator exerts too much force, the safety problem of the staff being injured is easy to occur when slipping. 2. When the movable wrench or the vice clamp is used, the force is unbalanced, the isolation valve ear is easy to be damaged, the scratch and the bending deformation are caused, and the force structure of the valve ear is broken.

[0004] For switching the isolation valve, it is not only inconvenient to operate, but also time-consuming and labor-consuming, especially in the emergency situation, the isolation valve needs to be quickly switched to avoid the hydraulic oil from leaking into the ballast tank to pollute the environment. In order to safely work and efficiently complete the maintenance and maintenance of the hydraulic butterfly valve isolation station on the spot, an special tool for switching the hydraulic butterfly valve isolation station is urgently needed. SUMMARY

[0005] The utility model discloses a quick switch tool for hydraulic butterfly valve isolation station, which has the advantages of simple structure and convenient operation.

[0006] The utility model discloses the following technical scheme: a quick switch tool for hydraulic butterfly valve isolation station, characterized by: including horizontal rod and vertical pipe, the horizontal rod fixedly connected in the one end of vertical pipe, be equipped with recess in the other end of vertical rod, first clamping piece and second clamping piece are fixedly connected on the two side walls of recess respectively, and the valve handle accommodating space is formed between first clamping piece and second clamping piece.

[0007] Further, one bolt is fixedly connected to each end of the horizontal rod.

[0008] Further, the first clamping piece, the second clamping piece and the vertical pipe are integrally formed.

[0009] Further, the cross rod, the vertical pipe, the first clamping piece and the second clamping piece are all made of stainless steel material.

[0010] Further, the length of the first clamping piece and the second clamping piece is 22-25mm, the width is 10-12mm, and the spacing between the first clamping piece and the second clamping piece is 3-4mm.

[0011] The utility model discloses the beneficial effect is: simple structure, through the cooperation of first clamping piece and second clamping piece, can closely adhere butterfly valve isolation station handle, is not easy to slip and is under stress evenly, and handle structure will not be damaged when operating, and the efficiency of opening and closing butterfly valve isolation station is high and safe. DRAWINGS

[0012] The utility model makes further explanation to the utility model with the drawings, but the embodiment in the drawing does not constitute any limitation to the utility model, and other drawings can be obtained according to the following drawings without the premise of creative labor for ordinary skilled person in the art.

[0013] Figure 1 It is the structure schematic diagram of the utility model. CONCRETE IMPLEMENTING METHOD

[0014] The drawings are only for example explanation, and can not be understood as the limitation of the patent, and in order to better illustrate the embodiment, some components of the drawings can be omitted, enlarged or reduced, and do not represent the size of actual product, and for ordinary skilled person in the art, it can be understood that some well-known structures and their description in the drawings can be omitted. The position relation in the drawings is only for example explanation, and can not be understood as the limitation of the patent.

[0015] As Figure 1 The utility model discloses a quick switch tool of hydraulic butterfly valve isolation station, including cross rod 1 and vertical pipe 2, cross rod 1 is fixedly welded in the upper end of vertical pipe 2, is equipped with the recess in the lower end of vertical rod, is fixedly connected with first clamping piece 3 and second clamping piece 4 respectively on the two side walls of recess, and the valve handle accommodating space is formed between first clamping piece 3 and second clamping piece 4.

[0016] Preferably, one bolt 5 is fixedly connected at each end of cross rod 1. By setting bolt 5, in some hydraulic butterfly valve isolation station switch difficulties, can use spanner or locking pliers to hold bolt 5 and use force.

[0017] Preferably, the first clamping piece 3, the second clamping piece 4 and the vertical pipe 2 are integrally formed. In addition, the cross rod 1, the vertical pipe 2, the first clamping piece 3 and the second clamping piece 4 are all made of stainless steel material. Adopting the structure design of integral and being made of stainless steel material can guarantee enough rigidity and ensure the stability of structure.

[0018] Further, the length of the first and second clamping pieces is 22 mm; the width is 10 mm; and the spacing between the first and second clamping pieces is 3 mm. With these sizes, the first and second clamping pieces can be fitted to the valve lug of the isolation valve and are not easy to slide off.

[0019] When the utility model is used, the valve handle accommodating space at the lower end of the vertical pipe 2 is aligned with the valve handle of the hydraulic butterfly valve isolation station, and is pressed downward, so that the valve handle is limited between the first and second clamping pieces, and the valve handle can be rotated by rotating the hand-pushed cross rod, that is, the hydraulic butterfly valve isolation station can be opened or closed.

[0020] The specific embodiments of the utility model are described above in combination with the drawings, but these descriptions cannot be understood as limiting the scope of the utility model, the protection scope of the utility model is defined by the appended claims, and any modification based on the claims of the utility model is within the protection scope of the utility model.
