Abstract
The utility model relates to a leak auto-closing safety valve for a liquefied gas cylinder, which is composed of a magnetic coil, a sliding sleeve, a hanger rod, a spring of the hanger rod, a positioning pin, a valve base, and a valve body. The utility model can match the automatic control circuit of ZL 93213689.3 and a device to form a safety valve which can automatically closed when the use spot occurs the gas leakage for avoiding the damage caused by the gas leakage and solving the hidden trouble of the liquefied gas cylinder. The utility model provides an effective device for solving the problem of the leakage of the liquefied gas.
Description
The utility model relates to the self acting stop valve of liquefied petroleum jar usefulness, the automatic closed safe valve when particularly leaking.
The leakage auto-closing safety valve of piped gas is invented by the present inventor, and patents, and sees ZL 93213689.3.But, yet there are no report to some extent so far for the automatic closed safe valve that the liquefaction coal gas tank is used.According to incompletely statistics, annual owing to use liquefaction coal gas tank hourglass gas, cause terrible disaster and resident's death, again and again generation.Therefore, seeking a kind of can in time the discovery and leak gas, in time report to the police and also can close the device of the outlet valve of propane gas automatically, is the problem of being unable to hold oneself back.
The purpose of this utility model is to provide a kind of safety valve that is exclusively used in the liquefaction coal gas tank.The automatic control circuit and the device that matches thereof that cooperate ZL93213689.3 just can be realized when using the place that leakage is arranged the safety valve that can close automatically.
Embodiment of the present utility model is as follows: it is made up of magnetic coil and sliding sleeve, suspension rod and suspension rod spring, locating stud, valve seat and valve body.Wherein magnetic coil is the top that is positioned at whole safety valve, and sliding sleeve is arranged in the magnetic coil, and smooth bore is arranged in the sliding sleeve.Suspension rod is positioned at the Lower Half of smooth bore, and the suspension rod lower end contacts with switch in the reduction valve, and the suspension rod spring is positioned at the bottom of suspension rod.The plush copper pin rod of locating stud is to snap in the groove part of the suspension rod first half, and valve body is positioned at the outside of suspension rod, and valve seat then is positioned at the bottom of valve body, is the lower end and the suspension rod spring of suspension rod in the valve seat.
Following preference is described in detail the utility model:
Fig. 1 is the internal structure sketch of the utility model leakage auto-closing safety valve.
As can be seen from the figure when the normal use of liquefaction coal gas tank was air tight, reduction valve switch (10) was the dotted portion of locating in the drawings.When leakage gas being arranged at positions such as the pipeline of reduction valve (15) back preamble section or other joints, gas-sensing probe (not marking among the figure) among the approved patent ZL93213689.3, when survey has gas leakage, make magnetic coil (5) charging produce magnetic by circuit (not marking among the figure), adhesive sliding sleeve (8), its suction is greater than the tension force of the suspension rod spring (4) that is welded in suspension rod (1) lower end, make sliding sleeve (8) along moving on the smooth bore (14), affect suspension rod (1) also to move on together like this, when the groove (12) of suspension rod (1) first half, the plush copper pin rod (11) of the pin that is positioned (9) when snapping in till.At this moment the switch (10) in the reduction valve is just upspring and is in closed condition.Thereby cutting off coal gas automatically effectively discharges from the liquefaction coal gas tank.Valve body (2) is to be connected with valve seat (13) with screw thread, is convenient to demolition and changes internal works, and coil case (3) is the usefulness with the coil of going bail for.Loam cake (6) also is to join with screw thread with the top of coil case (3), and it also is to join with screw thread and loam cake (6) that there is installation and maintenance port lid (7) in the center portion of loam cake (6), also is the usefulness as the demolition maintenance.Reduction valve (15) is a prior art.
After reduction valve switch (10) is closed as mentioned above, after in time handling leakage, with the handle (16) of handgrip locating stud (9) when pulling out to the right, according to its inner locating pin spring (17) of installing plush copper pin rod (11) is moved right, the tension force of mat suspension rod spring (4) is greater than the elastic force of reduction valve switch (10).Suspension rod (1) is depressed downwards together with sliding sleeve (8), and reduction valve switch (10) is just opened and is continued normally to supply gas.
The utility model has the advantages that:
(1) match with ZL93213689.3, the energy automatic-closing safety valve, thus stop The harm of leakage gas.
(2) simple in structure, reliable in action safety.
Claims (1)
1. leakage auto-closing safety valve that the liquefaction coal gas tank is used, it is special littlely to be that it is by magnetic coil (5) and sliding sleeve (8), suspension rod (1) and suspension rod spring (4), locating stud (9), valve seat (13) and valve body (2) are formed, wherein magnetic coil (5) is the top that is positioned at whole safety valve, sliding sleeve (8) is arranged in the magnetic coil (5), smooth bore (14) is arranged in the sliding sleeve (8), suspension rod (1) is positioned at the Lower Half of smooth bore (14), suspension rod (1) lower end contacts with switch (10) in the reduction valve (15), suspension rod spring (4) is positioned at the bottom of suspension rod (1), plush copper pin rod (11) in the locating stud (9) is to snap in the groove (12) of suspension rod (1) first half, valve body (2) is positioned at the outside of suspension rod (1), valve seat (13) then is positioned at the bottom of valve body (2), is the lower end and the suspension rod spring (4) of suspension rod (1) in the valve seat (13).
