High-pressure filtering pressure reducer and assembling method
Technical field
The present invention relates to a kind of pneumatic element, is a kind of high-pressure filtering pressure reducer and assembling method.
Background technique
At present, be provided with reduction valve in many pneumatic pipelines, import pneumatic pipeline again after by reduction valve the pressure of pneumatic pipeline inner high voltage gas medium being reduced, and the gas medium of deriving reduction valve is remained in the certain pressure scope.Reduction valve is as an indispensable accessory of pneumatic control valve, and main effect is with the decompression of source of the gas and is stabilized to a definite value, is used for regulating control so that modulating valve can obtain stable source of the gas power.
Wherein, most of pneumatic pressure-release valves are provided with filtering function, the ZL patent No. 96219819.6 as the Chinese patent literature publication, notice of authorization CN2290076Y, on September 2 1998 notice of authorization day, the model utility title " is filtered the decompression pressure governor ", the valve body center of this decompressor has the valve opening that communicates with two box chambeies, spool and valve seat are housed in the valve opening, and the spool rear end has had the spring I and the pressing plate of overvoltage balanced action, and the spool front end withstands on the spring seat that has scalable diaphragm in the regulator.The ZL patent No. 02201076.9 as the Chinese patent literature publication, notice of authorization CN2524034Y, December 4 2002 notice of authorization day, model utility title " gas pressure reducer ", this decompressor by have valve body, valve gap, adjusting screw rod, lamina membranacea, lamina membranacea pressure spring that pressure gauge connection, high low pressure inlet, outlet take over, be loaded on the valve seat between valve body high and low pressure air chamber, the spool that has goring push spring and spool tappet that is loaded in the valve support chamber constitutes.But the said goods production assembling is comparatively complicated, part replacements such as filtering box inner filter core, spool, safeguards comparatively inconvenience, does not have a drain function.
Summary of the invention
For overcoming the deficiency of above-mentioned existence, a kind of high-pressure filtering pressure reducer and assembling method with filtering function of providing to related domain is provided, make it can solve existing like product structural design and owe to improve and the not good enough technical problem of assembling method.The objective of the invention is to be achieved through the following technical solutions.
A kind of high-pressure filtering pressure reducer, this decompressor comprises water tumbler, valve body, spool, valve gap, and an end of described valve body is connected with valve gap, and the other end is connected with water tumbler, is provided with spool and valve core case in the valve body.The screw rod external diameter of pressure regulation nut component is provided with hexagon nut, and screw rod screws in valve gap, and screw rod is connected with spring lock block, and spring lock block is connected with stage clip one end, and the other end of stage clip is lived clever the connection with pressing plate.The top screws in pressing plate spirit alive, and the joint is provided with the 4th O-ring seals.Rotate the pressure regulation nut component, regulate stage clip and shrink or expand, push rod is stressed to move up and down, with the stressed spool that is passed to.
The embedded nylon6 chips of the described spool of its key points in design, push rod is
Push rod one end and top offset, and the push rod the other end is connected with spool; The 3rd O-ring seals is inserted in spool, and valve core spring is inserted in valve core case, and spool is connected with valve core case; Push rod, spool is stressed moves up and down, and by stressed increase of pressure regulation nut component regulating spool or minimizing, can increase or reduce the resistance of pressurized gas by spool, reaches the purpose of pressure regulation.The outside thread of described valve core case, water tumbler is connected with the internal thread of valve body, and water tumbler and valve core case joint are provided with second O-ring seals; Double threaded screw one end is connected with valve core case, and the filter core cover is connected with valve core case, and cyclone blade is connected with the filter core cover, the cyclone blade compressing tablet is connected with cyclone blade, filter core is connected with the cyclone blade compressing tablet, and filter core and cap are connected with filter core, and filter core and cap are connected with the double threaded screw the other end.Because gas enters valve body and produces swirling eddy, when swirling eddy passed through cyclone blade, dust, the globule in the gas were thrown away by cyclone blade, and cyclone blade has played guide functions.The two-way rotation of double threaded screw clamps filter core, cyclone blade compressing tablet, cyclone blade, filter core cover, and be fixed in valve core case.
The bottom of described water tumbler is connected with the water tumbler bottom, and the water tumbler bottom is connected with discharge valve seat, and the joint is provided with first O-ring seals, discharge valve seat by and cap be fixed in the water tumbler bottom; The spool that discharges water is connected with discharge valve seat, and the joint is provided with spring, and the spool that discharges water is fixed in discharge valve seat by split washer.Open the spool that discharges water, the water after the gas filtration is discharged water tumbler.
Described valve body and pressing plate clever joint alive is provided with y-shaped ring.When regulating the pressure regulation nut component, valve cavity remains sealing shape body.
Described top is "T"-shaped, and the top central shaft is provided with overflow hole.When pressure instability, gas enters valve gap from the overflow hole on the top, flows out by the valve gap air outlet hole, plays the effect of gas voltage stabilizing in the valve body.
Described spool, nylon6 chips, push rod three are connected as a single entity.Three in one makes the stressed more balanced of push rod, spool, improves stability, the Security of gas in valve body.
Described valve body is provided with high pressure gauge, plug.According to valve body mounting point into and out of pore in pipeline, pressure condition in the valve body can be read from high pressure gauge in the plug at regulation valve body hole exits place and the mounting point of high pressure gauge.
Its assembling method comprises water tumbler, valve core case, valve gap and valve body, and the assembling method of filter core; The outside thread that it is characterized in that described valve body one end is connected with the internal thread of valve gap, and the internal thread of the valve body the other end is connected with the outside thread of valve core case, water tumbler; Filter core in the described valve body is clamped between filter core and cap and the valve core case by double threaded screw, and double threaded screw one end is connected with the center hole of valve core case, and the double threaded screw the other end is connected with the center hole of filter core and cap.When double threaded screw clamps filter core, clamped cyclone blade compressing tablet, cyclone blade, filter core cover, and made cyclone blade compressing tablet, cyclone blade, filter core cover, filter core, filter core and cap be fixed in valve core case.Water tumbler, valve core case, valve gap and valve body, and the assembling mode of filter core have improved the working efficiency of assembling, have made things convenient for the care and maintenance to element kit.
The bottom of described water tumbler is connected by internal and external screw thread with the water tumbler bottom.By the mode of screw-thread fit, the assembling of water tumbler, maintenance, cleaning provide convenience.
The present invention is reasonable in design, and is simple in structure, has stable performance, safe and reliable, the characteristics of long service life, and its structure and assembling method have improved working efficiency for assembling, installation, use, maintenance, cleaning provide convenience.The present invention is applicable to various pneumatic pipeline mesohigh gas decompressions, filters, and is fit to produce in batches, and market prospects are good.
