Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the detailed description and specific examples, while indicating the invention, are given by way of illustration only.
Liquefied gas characteristics: when liquefied gas is stored in the sealed container, the pressure in the sealed container is not related to the amount of the liquefied gas and does not change (at the same temperature) along with the change of the amount of the liquefied gas, namely the pressure in the sealed container is kept unchanged, so that the sealed container is in gas-liquid two-phase balance.
An LPG diesel fork lift truck gas supply system comprises a first liquefied gas steel cylinder 1, a second liquefied gas steel cylinder 2, three high-pressure rubber pipes 3, a three-way joint 4, a first one-way valve 41 and a second one-way valve 42. The opening pressure values of the first check valve 41 and the second check valve 42 are the same; the first liquefied gas steel cylinder 1 and the second liquefied gas steel cylinder 2 are both horizontal, the nominal volume is 50L, and the maximum filling amount is 40L; the three-way joint 4 is an equal-diameter three-way joint.
The outlet valves of the first liquefied gas steel cylinder 1 and the second liquefied gas steel cylinder 2 are respectively communicated with a first joint and a second joint of a three-way joint 4 through a high-pressure rubber tube 3, a first one-way valve 41 used for enabling liquefied gas to flow from the first liquefied gas steel cylinder 1 to the three-way joint 4 is arranged in the first joint of the three-way joint 4, a second one-way valve 42 used for enabling liquefied gas to flow from the second liquefied gas steel cylinder 2 to the three-way joint 4 is arranged in the second joint, and a third joint of the three-way joint 4 is communicated with an engine liquefied gas fuel interface through the high-pressure rubber tube 3.
The third joint of the three-way joint 4 is communicated with an engine liquefied gas fuel interface of a 5-10t forklift through a high-pressure rubber tube 3, and when the 5-10t forklift is started to complete the forklift, outlet valves of a first liquefied gas steel cylinder 1 and an outlet valve of a second liquefied gas steel cylinder 2 need to be opened successively.
Case 1: the outlet valve of the first liquefied gas steel cylinder 1 is opened first, and the outlet valve of the second liquefied gas steel cylinder 2 is opened after the first liquefied gas steel cylinder 1 starts to supply gas.
Liquefied gas in the first liquefied gas steel cylinder 1 flows out of the first liquefied gas steel cylinder 1 under the action of pressure, passes through the high-pressure rubber pipe 3, backs up the first single valve 41 of the three-way joint 4, passes through the third joint of the three-way joint 4, and finally enters an engine of a 5-10t forklift from the high-pressure rubber pipe 3;
the liquefied gas in the second liquefied gas steel cylinder 2 flows out of the cylinder under the action of pressure and flows to the three-way joint 4 through the high-pressure rubber tube 3, but at the moment, the pressure on the left side and the right side of the second check valve 42 is the same (both are equal to the pressure in the second liquefied gas steel cylinder 2, and the pressure in the first liquefied gas steel cylinder 1 is the same as that in the second liquefied gas steel cylinder 2), so that the liquefied gas in the first liquefied gas steel cylinder 1 can be supplied to the engine of the 5-10t forklift at this moment.
With the operation of the engine, the liquefied gas in the first liquefied gas cylinder 1 is continuously reduced, but the pressure of the liquefied gas is kept unchanged due to the characteristics of the liquefied gas, so that the engine always consumes the liquefied gas in the first liquefied gas cylinder 1, and the pressure of the liquefied gas in the first liquefied gas cylinder 1 is not reduced until the pressure of the liquefied gas in the first liquefied gas cylinder 1 is used up. At this time, the second check valve 42 is pushed open, and liquefied gas in the second liquefied gas cylinder 2 enters the engine of the 5-10t forklift from the high-pressure rubber tube 3 through the third joint. At the same time, the first check valve 41 is closed, and at this time, the first liquefied gas cylinder 1 may be removed or replaced.
Case 2:
the outlet valve of the second liquefied gas steel cylinder 2 is opened first, and after the second liquefied gas steel cylinder 2 supplies gas normally, the outlet valve of the first liquefied gas steel cylinder 1 is opened.
The liquefied gas in the second liquefied gas steel cylinder 2 flows out of the second liquefied gas steel cylinder 2 under the action of pressure, passes through the high-pressure rubber pipe 3, backs up the second single valve 42 of the three-way joint 4, passes through the third joint of the three-way joint 4, and finally enters the engine of the 5-10t forklift from the high-pressure rubber pipe 3;
liquefied gas in the first liquefied gas steel cylinder 1 flows out of the steel cylinder under the action of pressure and flows to the three-way joint 4 through the high-pressure rubber tube 3, but at the moment, the pressure on the left side and the right side of the first check valve 41 is the same (both are equal to the pressure in the first liquefied gas steel cylinder 1, and the pressure in the first liquefied gas steel cylinder 1 and the pressure in the second liquefied gas steel cylinder 2 are the same), so that the liquefied gas in the second liquefied gas steel cylinder 2 can be supplied to an engine of a 5-10t forklift at the moment.
As the engine operates, the liquefied gas in the second liquefied gas cylinder 2 is continuously reduced, but the pressure thereof is maintained due to the characteristics of the liquefied gas, so that the engine always consumes the liquefied gas in the second liquefied gas cylinder 2 until the pressure of the liquefied gas in the second liquefied gas cylinder 2 is reduced. At this time, the first check valve 41 is pushed open, and liquefied gas in the first liquefied gas cylinder 1 enters the engine of the 5-10t forklift from the high-pressure rubber tube 3 through the third joint. While the second non return valve 42 is closed, it is possible to remove or replace the second liquefied gas cylinder 2.
When the number of liquefied gas cylinders in a factory is less than 2, the system allows the operation of only one liquefied gas cylinder.
It will be understood by those skilled in the art that the foregoing is merely a preferred embodiment of the present invention, and is not intended to limit the invention to the particular forms disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims.
