Description
Technical field
The utility model is related to Nonwoven Machinery technical fields, and in particular to a kind of Nonwovens Line hydraulic station pressure
Valve.
Background technology
During Nonwovens Line, hydraulic station pressure valve needs reach accurately pressure control effect, could realize pressure
Fine tuning, meet the requirement of nonwoven product quality.
Utility model content
The utility model provides a kind of non-woven cloth production to make hydraulic station pressure valve reach accurately pressure control effect
Line hydraulic station pressure valve, solving the technical solution of technical problem is：
Nonwovens Line hydraulic station pressure valve, including valve deck, air bag, valve body, valve seat and valve rod are pacified on the valve body
Equipped with valve deck, valve body and valve deck form a cavity, and bonnet central portion is provided with stomata, under stomata, cavity top have air bag, air bag
Bottom centre position has valve rod, air bag that valve rod can control to move up and down；The stem outer circumference is cased with valve body, between valve rod and valve body
Intermediate position forms closed oil pocket, and valve body is equipped with oil inlet in oil pocket lower part, is equipped with oil outlet on oil pocket top, the valve body connects
It is connected to valve seat.
Preferably, the valve body and valve deck are equipped with matched screw hole, are bolted.
Preferably, the valve body is fastened on by hexagon socket head cap screw on valve seat.
The utility model has the advantages that：
The utility model is scientific and reasonable for structure, by reequiping Pneumatic hydraulic valve on the hydraulic oil circuit of hydraulic station, to change
The oil return for becoming hydraulic station controls the reflux size of hydraulic oil by controlling the high-low-position of valve rod, controls the ejection pressure of hydraulic cylinder
Power achievees the effect that pressure size is fine-tuning, makes control accuracy higher, the operation is more convenient.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
1. stomata, 2. valve decks, 3. air bags, 4. valve bodies, 5. oil outlets, 6. oil inlets, 7. valve seats, 8. valve rods.
Specific implementation mode
Below in conjunction with the attached drawing of the utility model, the technical solution of the utility model is clearly and completely described.
Nonwovens Line hydraulic station pressure valve, including valve deck 2, air bag 3, valve body 4, valve seat 7 and valve rod 8, the valve
Valve deck 2 is installed, valve body 4 and valve deck 2 form a cavity, and 2 central part of valve deck is provided with stomata 1, under stomata 1, cavity top on body 4
Portion has air bag 3,3 bottom centre position of air bag to have valve rod 8, air bag 3 that valve rod 8 can control to move up and down；8 periphery of the valve rod is cased with
Valve body 4, intermediate position forms closed oil pocket between valve rod 8 and valve body 4, and valve body 4 is equipped with oil inlet 6 in oil pocket lower part, in oil pocket
Top is equipped with oil outlet 5, and the valve body 4 is connected with valve seat 7.
Preferably, the valve body 4 and valve deck 2 are equipped with matched screw hole, are bolted.
Preferably, the valve body 4 is fastened on by hexagon socket head cap screw on valve seat 7.
When work, Pneumatic hydraulic valve is reequiped on the hydraulic oil circuit of hydraulic station, is controlled by controlling the high-low-position of valve rod 8
The reflux size of hydraulic oil processed adjusts 1 air pressure of air inlet, and regulating valve stem 8 moves up and down in valve body 4, changes oil inlet 6 and goes out
Aperture between hydraulic fluid port 5, and then reach the hydraulic pressure for changing oil inlet 6, hydraulic oil enters valve body by oil inlet 6, by 5 row of oil outlet
Go out, to control the ejection pressure of hydraulic cylinder, achieve the effect that pressure size is fine-tuning, controls oily intraluminal fluid in this way
The circuit of pressure oil can more precisely, faster achieve the effect that adjust pressure.
Above-described embodiment does not limit the utility model in any way, every by the way of equivalent substitution or equivalent transformation
The technical solution of acquisition is all fallen in the scope of protection of the utility model.
