It is connected to the valve plug for blocking air inlet.The valve rod of current high pressure gas valve is not easy to control in motion, its motion bit
Put trend fuzzyyer, staff can not observe directly valve rod location from outside it is impossible to preferably control valve
Working condition.
Utility model content
The purpose of this utility model is that provides one kind to be easy to control and carry instruction function to solve the above problems
High pressure gas control valve door.
This utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of high pressure gas control valve door, including valve body and servo electric jar, described valve body is provided with valve rod, air chamber, enters
QI KOU and gas outlet, one end of described valve rod is worn to described air chamber and is connected with valve plug, in described air chamber simultaneously with described enter
QI KOU and described gas outlet communicate, and are additionally provided with instruction room, described instruction interior is provided with the finger of line with a scale in described valve body
Show plate, the other end of described valve rod is located at described instruction interior and is fixedly connected with the push rod of described servo electric jar, described valve
Pointer is provided with bar, described pointer points to the graduation mark of described indicator board.
Preferably, the described air inlet position being connected with described air chamber is cone structure, the outer surface of described valve plug be with
The cone structure that described air inlet matches.
Preferably, described valve rod and the junction of described valve body are provided with rubber gasket.
Preferably, it is bolted in described valve body and guide cylinder is installed, described valve rod passes through described guide cylinder.
Preferably, described instruction room is provided with lamella lucida, and a part for described indicator board and described valve rod is by described
It is indoor that isotropic disk is encapsulated in described instruction.
Preferably, described pointer is fixed on described valve rod by chuck, and described pointer is vertical with described valve rod.
The beneficial effects of the utility model are:
This utility model controls the motion of valve rod by servo electric jar, and control accuracy is high, can suitably reduce corresponding
Motion auxiliary component, control process is more convenient, and is able to observe that the fortune of valve rod by the indoor indicator board of instruction and pointer structure
Dynamic position, staff can preferably grasp the working condition of valve when safeguarding.
Brief description
Fig. 1 is the structural representation of high pressure gas control valve door described in the utility model；
In figure: 1- valve body, 2- air inlet, 3- valve plug, 4- gas outlet, 5- air chamber, 6- rubber gasket, 7- bolt, 8- valve
Bar, 9- lamella lucida, 10- servo electric jar, 11- pointer, 12- indicator board, 13- instruction room, 14- guide cylinder.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings:
As shown in figure 1, this utility model includes valve body 1 and servo electric jar 10, valve body 1 is provided with valve rod 8, air chamber 5, enters
QI KOU 2 and gas outlet 4, one end of valve rod 8 is worn to air chamber 5 and is connected with valve plug 3, in air chamber 5 simultaneously with air inlet 2 and giving vent to anger
Mouthfuls 4 communicate, and are additionally provided with instruction room 13 in valve body 1, are provided with the indicator board 12 of line with a scale in instruction room 13, valve rod 8 another
One end is located in instruction room 13 and is fixedly connected with the push rod of servo electric jar 10, valve rod 8 is provided with pointer 11, pointer 11 refers to
Graduation mark to indicator board 12.
Air inlet 2 position being connected with air chamber 5 is cone structure, and the outer surface of valve plug 3 is the cone matching with air inlet 2
Face structure, this structure makes the sealing effectiveness of valve plug 3 more preferably, and service life is longer.
In order to avoid gap between valve rod 8 and valve body 1 for the gas in air chamber 5 is run out of, valve rod 8 is connected with valve body 1
Position is provided with rubber gasket 6.
So that structure is more reliable and more stable during valve rod 8 motion, in valve body 1, guide cylinder is installed with by bolt 7
14, valve rod 8 passes through guide cylinder 14.
Instruction room 13 is provided with lamella lucida 9, and a part for indicator board 12 and valve rod 8 is encapsulated in instruction room by lamella lucida 9
In 13.Instruction room 13 is isolated from the outside by lamella lucida 9, nor affects on staff and observes the situation in instruction room 13.
Pointer 11 is fixed on valve rod 8 by chuck, and pointer 11 is vertical with valve rod 8.
The operation principle of this utility model high pressure gas control valve door is as follows:
When the valve is open, gas enters air inlet chamber 5 from air inlet 2, then discharges from gas outlet 4.When needing to adjust valve port
During size, can be by servo electric jar 10 continuous control valve rod 8 axially-movable so that between the taper surface of valve plug 3 and air inlet 2
Gap either large or small.During valve rod 8 axially-movable, change in location on indicator board 12 for the pointer 11, by scale
Line is able to observe that the variable quantity of valve rod 8 position.
These are only preferred embodiment of the present utility model, not in order to limit this utility model, all in this practicality
Any modification, equivalent and improvement made within new spirit and principle etc., should be included in guarantor of the present utility model
In the range of shield.
