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
The present invention relates to a kind of in tank body the oil filling riser of conveyance fluid material, especially a kind of can be when tank body be full of by fluid the valve on the SELF CL delivery duct, cut off the oil filling riser that has the anti-overflow system of fluid passage.
Background technology
At present, the oil filling riser of prior art does not have the anti-overflow system, with its in tank body the conveyance fluid material when tank body is full of by fluid, can not SELF CL carry the valve on the delivery duct, fluid overflows tank body and often takes place, particularly when carrying fuel oil, Hazardous Chemical Substances, bring big potential safety hazard very.
Summary of the invention
Technical matters to be solved by this invention provide a kind of can be when tank body be full of by fluid the valve on the SELF CL delivery duct, cut off the oil filling riser that has the anti-overflow system of fluid passage.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of oil filling riser that has the anti-overflow system, the epicoele oil inlet that is communicated with the epicoele of pressure on-off valve by pressure on-off valve, oil filling riser, with the cavity of resorption of pressure on-off valve, the epicoele oil outlet pipe that the epicoele of pressure on-off valve is communicated with the oil outlet of pressure on-off valve, the manual regulation valve that is installed on the epicoele oil outlet pipe are formed, fuel-displaced isocon of epicoele that be arranged in parallel with oil filling riser in parallel on the epicoele oil outlet pipe vertically is mounted with the buoyancy on-off valve of controlling the fuel-displaced isocon of epicoele in the oil outlet section of oil filling riser.The present invention is equipped with bi-bit bi-pass priority valve and the fuel-displaced isocon manual modulation valve of epicoele on the fuel-displaced isocon of epicoele.The fuel-displaced isocon manual modulation valve of epicoele of the present invention is installed in after the bi-bit bi-pass priority valve.When pressure oil P enters pressure on-off valve cavity of resorption, and regulate the valves by oil inlet and to enter pressure on-off valve epicoele.When bi-bit bi-pass priority valve no power, two position two-way valve is in closed condition.Equate (ignoring) according to handkerchief Si Kadinglv upper and lower cavity pressure along the stroke pressure loss.On this moment upper cavity pressure F=1/4 π D
2* P, under the following cavity pressure F=1/4 π (D
2-d
2) P, F is last greater than under the F, at the piston of this power effect downforce on-off valve oil outlet is shut.When the bi-bit bi-pass priority valve was switched on, two were in opening state for two-port valve.Make epicoele oil by the fuel-displaced isocon of epicoele, being positioned at down to point at ball float deadweight effect lower plunger is path, and oil enters oil tank.Epicoele pressure P=h ρ this moment (ρ is up to 8 meters for oily density is about 0.8Kg/lh for the oil filling riser height) epicoele pressure maxim: Pmax=9.8 * 8 * 800=0.063MPa (ignoring) along the stroke pressure loss, on the epicoele maximum pressure Fmax=0.063 * 1/4 π D
2=0.016 π D
2Cavity of resorption pressure minimum value (oil pump minimum pressure) Pmin=0.2Mpa, under the following cavity pressure minimum value Fmin=0.2 * 1/4 π (D
2-d
2)=0.05 л (D
2-d
2); Design is as long as guarantee under the Fmin: on the Fmax=and 3 (1-d
2/ D
2) greater than 1, just can make on the piston of pressure on-off valve and move valve open.When liquid level rises to the ball float position, ball float promotes plunger and moves on together under buoyancy, the fuel-displaced isocon of epicoele is entered oil filling riser oil outlet section passage block.This moment, pressure on-off valve upper cavity pressure was greater than descending cavity pressure with valve closing.Thereby reach the effect of anti-overflow.
Solve the optimal technical scheme of its technical matters as the present invention:
The plunger sliding type on-off valve of buoyancy on-off valve of the present invention for constituting by ball float, plunger and tubular type valve body, at the middle part of plunger ring-like passage is arranged, the connected entrance that is connected with the oil outlet section and the fuel-displaced isocon of epicoele of oil filling riser is respectively arranged at the middle part of tubular type valve body, the connected entrance that is connected with the oil outlet section of oil filling riser is arranged on the top of tubular type valve body, the inner chamber running-fit of the face of cylinder of plunger and tubular type valve body, the bottom surface of ball float is higher than the end face of oil outlet section.
Solve the optimal technical scheme of its technical matters as the present invention:
The present invention is connected with standby pipes before the manual regulation valve of epicoele oil outlet pipe with after the fuel-displaced isocon manual modulation valve of epicoele, the shutoff valve valve is installed on standby pipes.Without the bi-bit bi-pass priority valve time, close the fuel-displaced isocon manual modulation valve of epicoele, open the shutoff valve on the standby pipes, but normal operation.
Solve the optimal technical scheme of its technical matters as the present invention:
The present invention is equipped with epicoele oil-feed manual modulation valve on the epicoele oil inlet.Regulate the opening degree of epicoele oil-feed manual modulation valve, scalable acts on the pressure on the pressure on-off valve piston, adjusts the speed that the pressure on-off valve is closed, opened.
The present invention so can effectively prevent the spillover when fluid is full of tank body, has guaranteed the safe transport of various fluids owing to adopted the anti-overflow system, has eliminated potential safety hazard.
