Abstract
The utility model belongs to the technical field of fuel gas convying and distribution equipment, a gas pressure regulator is disclosed. Its main technical characteristics does: including the valve body that has import, export, be provided with valve port and nest core valve opening in the valve body, be provided with the pressure regulating diaphragm that has the pressure regulating tray above the nest core valve opening, be provided with pressure regulating spring and pressure -regulating nut above the pressure regulating diaphragm, the pressure regulating tray on be provided with the upper end and run through the signal pipe who stretches out the valve body behind pressure regulating spring and the pressure -regulating nut, the signal pipe top is provided with position sensor, position sensor is connected with central processing unit. The utility model provides a gas pressure regulator, pressure regulating diaphragm reciprocate the signal pipe who drives on the pressure regulating tray and reciprocate, and position sensor transmits the signal pipe value of reciprocating for central processing unit, just can know the upper and lower change value of the inside pressure regulating diaphragm of gas pressure regulator at a distance to gas pressure's regulation is carried out according to actual conditions.
Description
Technical field
This utility model belongs to gas transmission and distribution equipment technical field, particularly relates to a kind of gas pressure regulator, governor that can observe internal pressure change.
Background technology
Natural gas needs to use gas pressure regulator, governor in course of conveying.The most novel gas pressure regulator, governor includes with import, the valve body of outlet, is provided with valve port and nest core valve opening in valve body, and nest core valve opening is provided above with the voltage regulation diaphragm with pressure regulation pallet, and voltage regulation diaphragm is provided above with pressure spring and look nut.During use, combustion gas is entered valve body by import, through valve port and nest core valve opening by exporting out.Under normal circumstances, below voltage regulation diaphragm, the gas pressure in cavity is kept in balance with pressure spring.When change occur in import, outlet gas pressure, below voltage regulation diaphragm, the gas pressure in cavity is Jun Heng with pressure spring breaks, and voltage regulation diaphragm moves up and down, and the ventilation quantitative change of nest core valve opening is big or diminishes, thus regulates pressure regulator outlet pressure.The changing value up and down of the internal voltage regulation diaphragm of this pressure regulator can not be known in outside, it is difficult to carry out the regulation of gaseous-pressure according to practical situation.
Utility model content
Technical problem to be solved in the utility model is just to provide a kind of gas pressure regulator, governor that can know the internal upper and lower changing value of voltage regulation diaphragm in outside.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is: include with import, the valve body of outlet, valve port and nest core valve opening it is provided with in valve body, nest core valve opening is provided above with the voltage regulation diaphragm with pressure regulation pallet, voltage regulation diaphragm is provided above with pressure spring and look nut, being provided with the signal pipe stretching out valve body after pressure spring and look nut are run through in upper end on described pressure regulation pallet, signal pipe top is provided with position sensor, and position sensor is connected with central processing unit.
Its additional technical feature is: the outer wall of described signal pipe is provided with numerical value indentation.
Gas pressure regulator, governor provided by the utility model, pressure regulation pallet is provided with the signal pipe stretching out valve body after pressure spring and look nut are run through in upper end, and signal pipe top is provided with position sensor, and position sensor is connected with central processing unit.During use, combustion gas is entered valve body by import, through valve port and nest core valve opening by exporting out.Under normal circumstances, below voltage regulation diaphragm, the gas pressure in cavity is kept in balance with pressure spring.When change occur in import, outlet gas pressure, below voltage regulation diaphragm, the gas pressure in cavity is Jun Heng with pressure spring breaks, and voltage regulation diaphragm moves up and down, and the ventilation quantitative change of nest core valve opening is big or diminishes, thus regulates pressure regulator outlet pressure.Voltage regulation diaphragm moves up and down and drives the signal pipe on pressure regulation pallet to move up and down, signal pipe is moved up and down value and is transferred to central processing unit by position sensor, the most just can know that the internal upper and lower changing value of voltage regulation diaphragm of gas pressure regulator, governor, thus carry out the regulation of gaseous-pressure according to practical situation.And the outer wall of signal pipe is provided with numerical value indentation, outside gas pressure regulator, governor can the internal upper and lower changing value of voltage regulation diaphragm of artificial observation, use more convenient.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model gas pressure regulator, governor.
Detailed description of the invention
Structure and operation principle to this utility model gas pressure regulator, governor are described in further details below in conjunction with the accompanying drawings.
As shown in Figure 1, this utility model gas pressure regulator, governor includes valve body 1, valve body 1 is with import 2, outlet 3, valve port 4 and nest core valve opening 5 it is provided with in valve body 1, nest core valve opening 5 is provided above with the voltage regulation diaphragm 7 with pressure regulation pallet 6, voltage regulation diaphragm 7 is provided above with pressure spring 8 and look nut 9, the signal pipe 10 stretching out valve body 1 after pressure spring 8 and look nut 9 are run through in upper end it is provided with on pressure regulation pallet 6, signal pipe 10 top is provided with position sensor 11, position sensor 11 is connected with central processing unit 12, and the outer wall of signal pipe 10 is provided with numerical value indentation 13.
When gas pressure regulator, governor provided by the utility model uses, combustion gas is entered valve body 1 by import 2, through valve port 4 and nest core valve opening 5 by outlet 3 out.Under normal circumstances, the gas pressure in voltage regulation diaphragm 7 cavity below is kept in balance with pressure spring 8.When import 2, export 3 gas pressures change occurs time, gas pressure in voltage regulation diaphragm 7 cavity below is Jun Heng with pressure spring 8 to be broken, and voltage regulation diaphragm 7 moves up and down, and nest core valve opening 5 quantitative change of ventilating greatly or diminishes, thus regulates pressure regulator outlet pressure.Voltage regulation diaphragm 7 moves up and down and drives the signal pipe 10 on pressure regulation pallet 6 to move up and down, signal pipe 10 is moved up and down value and is transferred to central processing unit 12 by position sensor 11, the most just can know that internal voltage regulation diaphragm about 7 changing value of gas pressure regulator, governor, thus carry out the regulation of gaseous-pressure according to practical situation.And the outer wall of signal pipe 10 is provided with numerical value indentation 13, outside gas pressure regulator, governor can internal voltage regulation diaphragm about 7 changing value of artificial observation, use more convenient.
This utility model is not limited only to above-mentioned form, but no matter is to use which kind of form, as long as structure is identical with this utility model, both falls within protection domain of the present utility model.
