Abstract
An orderly automatic gas control disc is characterized in that: a sequence valve 3 is arranged on the high-pressure, central-pressure, low-pressure gas tube, and the outlet of the sequence valve is connected with a unilateral valve 4 and a ball valve respectively; the ball valve 5 is connected with the pressure gauge 7 through the outlet connector 6. No matter how the pressure is changed at the outlet of every unit, the utility model can still provide steady charged pressure, therefore, the orderly automatic gas control is reliably realized. The utility model has a compact structure, easy installation and great security as well as saves labor power.
Description
One, technical field:
The utility model relates to a kind of air pressure ventilating control device, especially automatic sequence ventilating control dish.
Two, background technique:
At present, the high, medium and low voltage loading line of the ventilating control dish of domestic use is made up of suction tude, ball valve, pressure gauge, steam outlet pipe etc., connects by steel pipe is straight-through between them.Each is organized loading line and communicates with straight-through outlet pipe again.Realize to each air cylinder inflation with manually controlling by the ball valve that is installed on each inflation group.The inflation pressure of this device can not be set and adjust, and what can not keep-up pressure because of the variation of outlet pressure is constant, can not realize the automatic sequence ventilating control, must manually be controlled by the people.As will be when the high pressure group be inflated, must close outlet pipe, the ball valve on middle pressure gas tube and the low inflation pipeline is opened high pressure group ball valve then, could inflate to high-pressure gas cylinder, when being charged to required pressure, close high pressure group ball valve, open the ball valve on next pipeline of organizing the needs inflation again, this inflation dish complex structure, the assembling difficulty, poor stability takies human resources.
Three, summary of the invention:
The purpose of this utility model provides a kind of automatic sequence ventilating control dish, the linkage structure on the ventilating control coil pipe road by changing present domestic use, solving inflation pressure can not set and adjust, meet the variation of outlet pressure, inflation pressure can not keep constant problem, can realize the automatic sequence ventilating control safely and reliably.
Concrete scheme of the present utility model is: a kind of automatic sequence ventilating control dish, comprise: casing, inlet attack, sequence valve, one-way valve, ball valve, outlet connection, pressure gauge, it is characterized in that: the outlet of the sequence valve on the high, medium and low voltage loading line is connected with one-way valve and ball valve respectively, and ball valve connects pressure gauge again through outlet connection.
Adopt such scheme,, can both provide stable inflation pressure, and pressure can be set and adjust no matter how outlet pressure changes, adopt spring machinery sequence valve, can realize the automatic sequence ventilating control safely and reliably, this control panel compact structure, assembling is easy, and Security is good, saves manpower.It is the desirable automatic sequence control inflator of domestic each CNG gas station.
Four, description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of sequence valve 3 among Fig. 1.
Five, embodiment:
Below in conjunction with drawings and Examples the utility model is further specified:
Please see Figure 1, Fig. 2, the utility model is made up of casing 1, inlet attack 2, sequence valve 3, one-way valve 4, ball valve 5, outlet connection 6, pressure gauge 7, it is characterized in that: the outlet of the sequence valve 3 on the high, medium and low voltage loading line is connected with one-way valve 4 and ball valve 5 respectively, and ball valve 5 connects pressure gauge 7 again through outlet connection 6.
From Fig. 1, Fig. 2 also as can be known: sequence valve 3 is spring mechanical valve.
Working principle of the present utility model is: pressurized gas is after inlet attack 2 enters high pressure group sequence valve 3, and the pressurized gas that is flowed out by outlet is divided into two-way by tee union.One the tunnel through one-way valve 4, ball valve 5 enters high-pressure gas cylinder, the inlet of pressure group sequence valve 3 during another road flow to, middle pressure group sequence valve 3 is preset with certain back pressure (as 10Mpa), when high pressure group pressure gauge 7 show reach in during the default back pressure value 10Mpa of pressure group sequence valve 3, be divided into two-way by middle pressure group tee union again after pressure group sequence valve 3 flowed out during gas just can enter.Pressure group one-way valve 4 in one road warp is pressed air cylinder during ball valve 5 enters, and at this moment pressurized gas will charge into pressurized gas to height, two groups of gas cylinders of middle pressure simultaneously under the effect of sequence valve 3.Another road flow to the inlet of low pressure group sequence valve 3, low pressure group sequence valve 3 has been preset the higher back pressure (as 20Mpa) of middle pressure group sequence valve 3, when the inflation pressure of two groups of high, middle pressures all reaches the setting value of 20Mpa, low pressure group sequence valve 3 just is opened, compressed air stream is to low pressure group one-way valve 4, and ball valve 5 enters the low pressure air cylinder.Pressurized gas will be inflated simultaneously to high, three groups of gas cylinders of mesolow this moment, have only when pressure high, three groups of gas cylinders of mesolow all reach certain value (as 25Mpa), and compressor just stops inflation.In gas replenishment process, the gas cylinder that this device can reduce from each pressure of trend is make-up gas at any time, and whole process does not need manual operation fully, realizes the automatic sequence ventilating control smoothly.
