Embodiment Construction

[0015] As shown in Figure 1-2, a crane pipe with an overflow prevention system consists of a pressure on-off valve 1 and a crane pipe 15, which connect the lower chamber of the pressure on-off valve 1 with the upper chamber of the pressure on-off valve 1 The upper chamber oil inlet pipe 3, the upper chamber oil outlet pipe 5 connecting the upper chamber of the pressure on-off valve 1 with the oil outlet of the pressure on-off valve 1, and the manual adjustment valve 4 installed on the upper chamber oil outlet pipe 5, its characteristics Yes: an upper chamber oil outlet shunt pipe 14 parallel to the crane pipe 15 is connected in parallel to the upper chamber oil outlet pipe 5, and a control upper chamber oil outlet shunt pipe 14 is vertically installed and fixed on the oil outlet section 10 of the crane pipe 15 buoyancy on-off valve. The buoyancy on-off valve is a plunger sliding on-off valve composed of a float 11, a plunger 12 and a tubular valve body 13. There is an annular ...

Abstract

The invention discloses a crane tube conveying fluid matter into a tank body, relating to a crane tube which can automatically close a valve on a conveying pipeline and cut off a fluid channel when the tank body is full of fluid and is provided with an overflow preventing system. The crane tube consists of a pressure on-off valve, a crane tube, an oil inlet pipe for an upper-cavity, an oil outlet pipe for the upper-cavity, as well as a manual regulating valve, wherein the oil inlet pipe for the upper-cavity communicates a lower cavity of the pressure on-off valve with an upper cavity of the pressure on-off valve, the oil outlet pipe for the upper-cavity communicates the upper cavity of the pressure on-off valve with an oil outlet of the pressure on-off valve, and the manual regulating valve is arranged on the upper-cavity oil outlet pipe. The oil outlet pipe for the upper-cavity is in parallel connection with an oil outlet shunt tube for the upper-cavity parallel to the crane tube; and a buoyancy on-off valve controlling the oil outlet shunt tube for the upper-cavity is vertically fixed on an oil outlet segment of the crane tube. With the overflow preventing system, the crane tube can effectively prevent overflow phenomena when the tank body is full of the fluid, guarantee the safe conveying of various fluids and eliminate potential safety trouble.

Description

technical field [0001] The invention relates to a crane tube for conveying fluid substances into a tank, in particular to a crane tube with an overflow prevention system that can automatically close a valve on a delivery pipeline and cut off a fluid passage when the tank body is filled with fluid. Background technique [0002] At present, the crane pipe in the prior art does not have an overflow prevention system, and when the tank is filled with fluid, the valve on the delivery pipeline cannot be automatically closed when the tank is filled with fluid, and the fluid overflows the tank often, especially in the transportation Fuel and chemical dangerous goods will bring very big safety hazards. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a crane pipe with an overflow prevention system that can automatically close the valve on the delivery pipeline and cut off the fluid passage when the tank is filled with flui...
