Description

A fixing tool for removing copper sleeve of valve under pressure

technical field

The utility model relates to a tool for mechanical maintenance of valves, in particular to a fixing tool for removing copper sleeves of valves under pressure.

Background technique

In the process of mechanical maintenance, during the disassembly process of the copper sleeve of the valve, when the disassembly is under pressure, the phenomenon of water spray will occur when the copper sleeve of the valve is clamped by the pipe wrench; normal work. Moreover, this method has low working efficiency, high labor intensity, and easy damage to the copper sleeve of the valve. Therefore, it is an urgent problem to be solved in this field to provide a fixing tool for removing the copper sleeve of the valve under pressure.

Utility model content

The purpose of the utility model is to provide a fixing tool for removing the valve copper sleeve under pressure. The use of the tool has low labor intensity and high work efficiency, and the valve copper sleeve will not be damaged during the disassembly process, which ensures the safe operation of the maintenance personnel.

The purpose of this utility model is achieved through the following technical solutions.

A fixing tool for removing a copper sleeve of a valve under pressure, comprising a pair of thread clamps arranged symmetrically to each other. The inner wall of the ring is provided with internal threads of the collar, and bolt holes are arranged on both sides of the semicircular arc of the threaded clamp plate, and the bolts can penetrate into the bolt holes and be locked by nuts.

Preferably, the semicircle radius of the threaded collar matches the diameter of the valve stem.

Compared with the prior art, the utility model has the beneficial effects that the tool has a simple processing structure, the raw material is the most commonly used steel, is convenient to operate, can be used in harsh environments and has no environmental pollution. After the device is implemented, the operation stability of the equipment system is greatly reduced, the scope of the isolation system is reduced, and the safety of maintenance personnel is effectively guaranteed.

In the figure: 1. thread clamping plate; 2. bolt; 3. threaded collar; 4. nut; 5. bolt hole; 6. inner thread of the collar.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

As shown in Figure 1 and Figure 2, the fixing tool for removing the copper sleeve of the valve under pressure includes a pair of thread clamps 1 arranged symmetrically to each other. The structure is a threaded collar 3, the inner wall of the threaded collar 3 is provided with a collar internal thread 6, and the threaded clamp plate 1 is provided with bolt holes 5 on both sides of the semicircle arc, and the bolt 2 can penetrate into the bolt hole 5 and be locked by the nut 4.

The main function of the valve copper sleeve removal and fixing tool is to connect the valve stem with the external threaded clamping plate with bolts, so as to fix the valve stem and realize the purpose of safely disassembling the valve copper sleeve under pressure. When using the copper sleeve of the valve to disassemble the fixing tool, select the corresponding threaded clamping plate according to the valve model, and the radius of the semi-circle with the threaded collar matches the diameter of the valve stem. It is suitable for fixing the valve stem when the copper sleeve of gate valve and globe valve is removed. The purpose of safely replacing the copper sleeve of the valve under pressure is achieved. On the other hand, it does not affect the normal work of the operating system, greatly reduces the scope of system isolation, and effectively improves work efficiency.

The above content is a further detailed description of the utility model in conjunction with specific preferred embodiments. It cannot be determined that the specific embodiment of the utility model is limited to this. Under the premise of the new concept, some simple deduction or replacement can also be made, which should be regarded as belonging to the utility model and determined by the submitted claims. Scope of patent protection.
