specific Embodiment approach 1

[0010] Specific implementation mode one: combine figure 1 and figure 2 Explain that a high-speed valve wrench described in this embodiment includes a wrench head 1, a handle 2 and an adjustment bolt 3. The wrench head 1 is fixedly connected to the front end of the handle 2, and the front end of the wrench head 1 is provided with a U-shaped through groove 1 -1, the notch of the U-shaped through groove 1-1 is arranged in the middle part of the front end of the wrench head 1, and the middle part of the rear end of the U-shaped through groove 1-1 is provided with an adjusting bolt 3, and the axis direction of the adjusting bolt 3 is aligned with the direction of the wrench head 1. The front side is vertical.

[0011] In such a design, the U-shaped channel 1-1 of the connecting valve wrench is stuck in the annular groove on the top of the valve stem, and the lower end of the adjusting bolt 3 is stuck on the connecting valve housing, and the use height of the wrench is controlled ...

specific Embodiment approach 2

[0012] Specific implementation mode two: combination figure 1 and figure 2 It is explained that the end of the adjustment bolt 3 in this embodiment is hinged with a roller 4 . Other compositions and connection methods are the same as those in Embodiment 1.

[0013] Such a design can reduce the friction between the adjusting bolt 3 and the connecting valve casing, thereby reducing resistance and improving work efficiency.

specific Embodiment approach 3

[0014] Specific implementation mode three: combination figure 1 and figure 2 Note that the depth of the U-shaped through groove 1-1 in this embodiment is 40mm, and the groove width of the U-shaped through groove 1-1 is 28mm. Other compositions and connection modes are the same as those in Embodiment 1 or 2.

[0015] It is designed in this way to match the commonly used external dimensions of high-addition valves. In actual application, it can be adjusted according to the external dimensions of different high-addition valves.

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

technical field [0001] The invention relates to an installation and disassembly tool, in particular to a high-addition valve wrench. Background technique [0002] The Gaojialiancheng valve is also a three-way valve, and its working principle is similar to that of a piston. When the high water level is higher than the III value, the electric contact will transmit the electric signal of the high water level to the high III value to the high water protection solenoid valve, and the high water protection solenoid valve will be opened, and the condensate water will be drawn from the condensate jellyfish pipe through the high water protection water as the high water level. Adding protection water and injecting water to open the high-filling valve using pressure to open the high-filling valve because of the difference in pressure between the upper and lower joint surfaces. At the same time, the high-filling water side directly enters the feed water pump through the high-filling byp...
