Abstract

The invention relates to an assembly and disassembly tool, in particular to a switching three-way valve wrench. The switching three-way valve wrench aims at solving the problems that an existing switching three-way valve is difficult to switch on or off. The switching three-way valve wrench comprises a wrench head, a handle and an adjusting bolt. The wrench head is fixedly connected to the front end of the handle. A U-shaped through groove is formed in the front end of the wrench head. A groove opening of the U-shaped through groove is formed in the middle of the front end face of the wrench head. The adjusting bolt is arranged in the middle of the rear end of the U-shaped through groove. The axis direction of the adjusting bolt is perpendicular to the front side face of the wrench head. The switching three-way valve wrench is used for switching on and switching off a switching three-way valve.

Description

A kind of high adding, is unified into valve spanner
Technical field
The present invention relates to a kind of installation and removal instrument, be specifically related to a kind of high adding to be unified into valve spanner.
Background technology
Height adds that to be unified into valve be again triple valve, and its operation principle is similar to piston. In the time that height adds the high III value of water level, electric contact is by heightThe signal of telecommunication that adds the high III value of water level is passed to high pressure heater protection magnetic valve, and high pressure heater protection magnetic valve is opened by high pressure heater protection water from solidifyingBear water female pipe and attract a road condensate water and as the water filling of high pressure heater protection water, height is added and is unified into valve and utilizes pressure that height is added and is unified into valve and opens,Because combine between the higher and lower levels, the difference of the surface pressure simultaneously high side that adds water that opens it directly adds bypass and enters feed pump through rising through too highCompress into into boiler.
In thermal power plant, high-pressure heater main application is that heating boiler feedwater improves feed temperature, reduces cold source energy,Improve heat utilization rate. But because boiler feedwater pressure is very high, once height adds internal helicoid tracheal rupture, high topped up with water, high pressureFeedwater will be returned to steam turbine along extraction line, causes water slug accident. Therefore, import and export and be provided with connection at high-pressure heaterBecome valve. In the time that height adds water level measuring and protecting device and sends the high signal of water level, be unified into valve events, cut off the high Inlet and outlet water that adds, drop intoHeight adds bypass operation, prevents that water slug accident from occurring. Due to long-term operation, height adds and is unified into the easy fouling of valve valve rod and bite occursPhenomenon, adds height to be unified into valve to be devoted oneself to work very difficult, has also strengthened the high maintenance workload that is unified into valve that adds simultaneously. Now without specialIndustry instrument adds and is unified into valve and opens height, can only rely on to start water and open, but start water system due to running timeLong, reliability is not high.
Summary of the invention
The present invention solves existing height to add the problem that is unified into valve opening and closing difficulty, and then proposes a kind of high adding and be unified into valve and pullHand.
The present invention solves the problems of the technologies described above the technical scheme of taking to be: the present invention includes driving end, handle and adjustment bolt,Driving end is fixed in the front end of handle, and the front end of driving end is provided with U-shaped groove, and the notch of U-shaped groove is arranged on driving endThe middle part of front end face, the middle part of U-shaped groove rear end is provided with adjustment bolt, adjusts the axis direction of bolt and the front side of driving endFace is vertical.
The invention has the beneficial effects as follows:
When height adds when being unified into valve and dropping into, outlet non-return valve is opened, and height adds equalizer valve, be unified into valve protection water drain valve opens,And it is motionless or time slow in one's movements to be unified into valve valve rod, and the U-shaped bayonet socket that is unified into valve spanner is stuck in the cannelure at valve rod top,Height adjustment bolt lower end is stuck in and is unified on valve chest, adjusts after spanner height, and moving wrench gently, makes to join journey valve slowOpen. The invention provides a kind of Wrench of specialty, simple to operation, the time consuming time is short, and effect is remarkable, effectivelySolved and high added the problem that is unified into valve opening and closing difficulty, be convenient to height and add and be unified into valve and carry out inspection and maintenance, improved workMake efficiency, the workload while having reduced maintenance.
Brief description of the drawings
Fig. 1 is overall structure schematic diagram of the present invention;
Fig. 2 is the top view of Fig. 1.
