Problems solved by technology

[0002] With the development of science and technology and the continuous expansion of the production capacity of mining enterprises, the equipment used in mines is also rapidly developing in the direction of large-scale. The engine power assembled on the equipment is increasing, and the fuel consumption is increasing accordingly. Equipment manufacturers have greatly increased the volume of fuel tanks to reduce the number of refueling and ensure the endurance and effective running time of the equipment, but the phenomenon of fuel loss and theft also follows.

Embodiment 1

[0008] The anti-theft one-way valve of the present invention includes a valve body 1, two anti-theft nuts are installed in sequence at one end of the valve body 1, a valve core 2 is installed in the valve body 1, and a return spring 3 is sleeved on the top of the valve core 2 , The other side of the return spring 3 is equipped with a guide nut 4.

[0009] The end where the anti-theft nut is installed is the oil inlet, and the end where the guide nut 4 is installed is the oil outlet. Anti-theft nut A and anti-theft nut B are installed on the oil inlet end with self-locking threads. When installing, there should be enough space between the two anti-theft nuts to ensure the fuel flow. At the same time, the round holes on the two anti-theft nuts should be staggered from each other. To prevent sharp objects from passing through the top pressure spool 2. The valve core 2 cooperates with the valve body 1 to form a seal and one-way conduction. When installing, it should be in the sam...

Abstract

The invention relates to a valve, in particular to an anti-theft check valve. The anti-theft check valve comprises a valve body, two anti-theft nuts are sequentially installed at one end of the valve body, a valve element is installed inside the valve body, a reset spring is connected to the top end of the valve element in a sleeved mode, and a guiding nut is installed on the other side of the reset spring. The anti-theft check valve is connected between a rapid oil filling opening and an oil tank in series, accordingly, the oil filling procedure is simplified, the management difficulty is reduced, and fuel oil losses are prevented.

Description

technical field [0001] The present invention relates to a valve. Background technique [0002] With the development of science and technology and the continuous expansion of the production capacity of mining enterprises, the equipment used in mines is also rapidly developing in the direction of large-scale. The engine power assembled on the equipment is increasing, and the fuel consumption is increasing accordingly. Equipment manufacturers have greatly increased the volume of the fuel tank to reduce the number of refueling and ensure the endurance and effective running time of the equipment, but the phenomenon of fuel loss and theft also follows. Contents of the invention [0003] The invention relates to an anti-theft one-way valve which increases the reliability of a fuel anti-theft system. [0004] The anti-theft one-way valve includes a valve body, two anti-theft nuts are installed in turn on one end of the valve body, a valve core is installed in the valve body, a re...
