Technical field
The utility model belongs to the gas transmission and distribution equipment technical field, relates in particular to a kind of no valve port squirrel-cage pressure governor.
Background technique
Gas pressure regulator, governor is to be specially adapted in the gas transmission and distribution system being widely used in the gas transmission and distribution engineering as the combustion gas voltage adjusting device of pressure regulation, voltage stabilizing.Its effect is to regulate gas outlet pressure automatically, makes it be stabilized in a certain pressure range, satisfies the force value of customer requirements, satisfies usage requirement.The gas pressure regulator, governor of current use, its structure comprises the housing that has suction port, air outlet and valve seat, be provided with diaphragm in the housing, diaphragm top is provided with pallet, pressure adjusting spring, adjustable lever and adjusting nut, the diaphragm bottom is provided with the valve rod that is connected with pallet, and the valve rod bottom is provided with the valve alive that is complementary with valve seat.Pressure governor is when proper functioning, and air outlet pressure acts on the power of diaphragm bottom surface and power that pressure adjusting spring acts on the diaphragm end face reaches balance, and valve rod is static, and valve port is in normal open mode.When air outlet pressure raises, when the power that air outlet pressure acts on the diaphragm bottom surface acts on the power of diaphragm end face greater than pressure adjusting spring, diaphragm drives pallet and moves up, pallet moves up and drives valve rod and move up, valve rod drives the valve of living and moves up, the valve port of valve alive and valve base chamber reduces, and makes air outlet pressure reduce to recover normal value, thereby keeps normal air feed.When air outlet pressure reduces, when the power that air outlet pressure acts on the diaphragm bottom surface acts on the power of diaphragm end face less than pressure adjusting spring, diaphragm drives pallet and moves down, pallet moves down the drive valve rod and moves down, valve rod drives the valve of living and moves down, the valve port of valve alive and valve base chamber increases, and air outlet pressure is increased recover normal value, thereby keep normal air feed.The gas pressure regulator, governor of this structure, stem guiding produces frictional force, produces noise, and the precision of voltage regulation is lower.
The model utility content
Technical problem to be solved in the utility model just provides a kind of stable drive, and noise is little, the no valve port squirrel-cage pressure governor that the precision of voltage regulation is high.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: comprise the valve body that has import and outlet, be provided with the diaphragm that it is divided into epicoele and cavity of resorption in the valve body, be provided with filter, restrictor and pilot valve between import and outlet, restrictor is connected with epicoele by signal tube, be provided with guide cylinder, spring in the epicoele above the described diaphragm, be provided with and the contacted mouse cage that constitutes by many railings spaced apart of diaphragm in the cavity of resorption below the diaphragm.
Its additional technical feature is: the upper end of described valve body is provided with indicator of opening, and the indicating arm that the bottom is connected with guide cylinder passes epicoele and stretches into indicator of opening; Described indicator of opening is provided with displacement transducer; The railing of described mouse cage is radial even distribution.
When a kind of no valve port squirrel-cage pressure governor provided by the utility model uses, combustion gas enters in the valve body by import, arrive outlet via mouse cage, filter cleaning is passed through in one tunnel combustion gas of import simultaneously, enter and export the pilot valve that is communicated with through restrictor again, this moment epicoele and cavity of resorption isostasy, the pressure governor proper functioning.
When flow increases, when causing outlet pressure to reduce, the valve port of pilot valve is opened, and the pressure behind the restrictor descends, by signal tube the pressure of epicoele is reduced, diaphragm upper and lower cavity pressure disequilibrium, the diaphragm pressure spring moves up, and the gap between diaphragm and the mouse cage is increased, the throughput of combustion gas increases, cause outlet pressure to increase, recover setting value, set up a new balance.Thereby satisfy traffic requirement, keep the stable of outlet pressure.Vice versa.
When the pressure governor inlet pressure changes, when pressure rises, cause outlet pressure to rise, the valve port gap of pilot valve reduces, pressure behind the restrictor rises, and makes the pressure of epicoele rise the pressure disequilibrium of diaphragm upper and lower cavity by signal tube, spring stretches diaphragm is moved down, gap between diaphragm and the mouse cage is reduced, and the throughput of combustion gas reduces, and causes outlet pressure to reduce, recover setting value, set up a new balance.Thereby satisfy traffic requirement, keep the stable of outlet pressure.Vice versa.
A kind of no valve port squirrel-cage pressure governor provided by the utility model does not have valve port, directly uses the diaphragm seal mouse cage, has reduced the valve rod connection, has eliminated the frictional force that stem guiding produces, stable drive, and noise is little, precision of voltage regulation height.And the upper end of valve body is provided with indicator of opening, and the indicating arm that the bottom is connected with guide cylinder passes epicoele and stretches into indicator of opening, then can indicate the aperture between diaphragm and the mouse cage at any time.Indicator of opening is provided with displacement transducer, aperture can be transformed into electrical signal, and can teletransmission, realizes telecontrol.Mouse cage is a core component, and its shape and gap distribution directly influence the pressure governor performance, and railing is radial even distribution, helps dredging flow, reduces noise.And diaphragm directly is subjected to the inlet pressure effect, and its intensity will reach requirement, adopts the thickening elastomer diaphragm, strengthens with polyamide fabric in the middle of the rubber thickness, has satisfied requirement of strength.Diaphragm shapes is a butterfly, is easy to move up and down, and has reduced the variation of useful area, and diaphragm inner circular part branch is thicker than the edge section, helps sealing.
