Description
Technical field
The utility model is related to a kind of valves more particularly to a kind of two-seater to adjust pressure reducing valve.
Background technology
In order to reduce the pressure of pumped (conveying) medium, controlled usually on conveyance conduit using adjustable pressure-reducing valve.It is and present
Common adjusting structure of relief pressure valve is generally telescopic, and the sleeve of telescopic pressure reducing valve and flap are clearance fit, on sleeve
Multiple throttling windows are provided with, the shape of window determines the discharge characteristic of regulating valve, and the size of window influences regulating valve
Discharge coefficient plays the role of controlling outlet pressure well, and but its structure is complex, of high cost, in use for some time
Easily there is rough and uneven in surface phenomenon to sleeve in cracking or cracking, valve shaft surface, greatly reduce the service life of valve.
Utility model content
The purpose of this utility model is to provide a kind of two-seater and adjusts pressure reducing valve, above-mentioned existing for currently available technology to overcome
Deficiency, there is no the situations of sleeve strain.
The purpose of this utility model is realized by following structure, including：Valve body, valve body top connection upper end
Lid, the bottom connection bottom end cover of valve body is upper and lower in the valve body respectively to set a set of valve seat and spool, respectively upper valve base and upper
Spool and lower valve base and bottom spool, upper valve core and bottom spool are connected on valve rod.
The bottom end cover is equipped with pressure compensation opening.
The upper end cover is equipped with pressure compensation opening.
Pressure compensation opening also is provided on the upper end cover.
Valve rod outside the stretching valve body is equipped with valve stem sleeve, and valve stem sleeve is equipped with radiating fin.
The internal diameter of the upper valve base is greater than the outer diameter of bottom spool.
The upper valve core is linear or equal percentage shape, and bottom spool is linear or equal percentage shape.
Axle sleeve is equipped between the bottom end cover and valve rod, axle sleeve also is provided between end cap and valve rod.
The axle sleeve and valve rod cannot use the material of model of the same race.
The cooperation of two sets of spools of the utility model and valve seat, plays the role of two-stage decompression, structure is relative to sleeve
Formula adjusting pressure reducing valve is simpler, and spool and valve seat are unlikely to deform, and improve the service life of valve, and the adjusting pressure difference of valve
Greatly.Secondly by pressure compensation opening is increased, the resistance of valve opening and closing is reduced.Thirdly, by setting radiating fin, reduce valve
The temperature conduction of bar part has ensured the normal work of executing agency.
Description of the drawings
Fig. 1 is that figure is cutd open in the structural representation of the utility model.
Specific embodiment
The embodiment of the utility model as shown in Figure 1 includes：Valve body 1,1 top of valve body connection upper end cover 2, valve body 1
Bottom connects bottom end cover 3, and a set of valve seat and spool, respectively upper valve base 4 and upper valve core 5 are respectively set above and below in the valve body, with
And lower valve base 6 and bottom spool 7, upper valve core 5 and bottom spool 7 are connected on valve rod 8, upper valve base 4 coordinates with upper valve core 5, lower valve base 6
Coordinate with bottom spool 7.The bottom end cover 3 is equipped with pressure compensation opening 9, and pressure compensation opening also is provided on upper end cover 2.When valve rod 8
When moving down at the pressure compensation opening 9 of bottom end cover 3, gas in it or medium is allow to be put down by pressure by the extruding of valve rod 8
Weighing apparatus hole 9 is discharged to 1 inner cavity of valve body, is not in the phenomenon that blocking valve rod moves down.And the pressure compensation opening on upper end cover 2 can will overflow
Medium water conservancy diversion go back to 1 inner cavity of valve body.The top connection executing agency 12 of valve rod 8, by the keying of 12 control valve of executing agency.Institute
It states the valve rod 8 stretched out outside valve body 1 and is equipped with valve stem sleeve 10, valve stem sleeve 10 is equipped with radiating fin 11, and radiating fin 11 increases
The contact area of valve stem sleeve 10 and air, in order to the heat dissipation of 8 part of valve rod, reduces and is conducted to executing agency by valve rod 8
12 heat ensures that the operating temperature of executing agency 12 is normal.The internal diameter of the upper valve base 4 is greater than the outer diameter of bottom spool 7, makes
Bottom spool 7 can be passed through when valve is installed from upper valve base 4, consequently facilitating the assembling of valve.The upper valve core 5 is linear or waits
Percentage shape, bottom spool 7 are linear or equal percentage shape.Axle sleeve 13, upper end cover 2 and valve are equipped between the bottom end cover 3 and valve rod 8
Axle sleeve also is provided between bar 8.Upper end cover 2 uses the steel of similary model with axle sleeve 13, bottom end cover 3 with axle sleeve in order to prevent, and sends out
Raw mutually to glue situation because of the identical generation of material, axle sleeve 13 must use the material of different model with upper end cover 2 and bottom end cover 3, from
And facilitate the keying of valve.
To the above description of disclosed embodiment, those skilled in the art is enable to realize or use this reality
With novel, a variety of modifications to present embodiment are it will be apparent that as defined herein one to those skilled in the art
As principle can realize in other embodiments without departing from the spirit or scope of the present utility model.Therefore, it is all
Be with the same or similar technical solution of present embodiment, all fall in the scope of protection of the utility model.
