Description
Technical field
The utility model relates to actuator apparatus fields, more particularly to a kind of actuator with V-seal pair
Push rod.
Background technique
Air bladder actuator and air-cylinder type actuator are essential groups of regulating valve product in industrial process automation
At component, the movement of regulating valve is carried out by the pushrod movement of actuator.Because that must be stretched out after push rod and diaphragm or piston connection
Film head is outer or cylinder barrel is just able to achieve the connection with regulating valve rod outside, this stretches out membrane cover in push rod in the process or cylinder cap part must
It need be sealed, and the sealing quality at this directly affects the Control platform of actuator, sealing such as Fig. 1 is used at this traditional
" O " type sealing ring sealing, since push rod and " O " type sealing ring are dynamic sealing pairs, thus as the number of putter action increases
Add, " O " type sealing ring will generate abrasion, when abrasion loss reaches certain value (when being more than the compensation of " O " type sealing ring)
Gas leakage will be generated at sealing, to influence the unstable of putter action.In addition movement push rod is during the work time since outer wall is naked
Dew has certain dust, greasy dirt and solid particle and is adhered on the outer wall of movement push rod, into inside seal receptacle, therefore
Need to be arranged dust-proof asphalt felt to strike off the substance of push rod outer wall, but larger damage can occur in the long-term course of work for felt
Consumption causes the ability for scraping chalk dust removing to reduce.In addition to this, frictional dissipation occurs for the inner wall of push rod and seal receptacle, influences actuator
Sealing effect inside push rod.
Utility model content
The purpose of this utility model is to provide a kind of actuator push rods with V-seal pair, to solve sealing at present
Gas leakage, which occurs, for circle abrasion causes that sealing effect is poor, putter action is unstable, dust-proof asphalt felt chalk dust removing effect is poor and pushes away
The problem of frictional dissipation, occurs for the inner wall of bar and seal receptacle, to improve the service life of actuator push rod.
The utility model specifically uses following technical scheme to achieve the goals above:
A kind of actuator push rod with V-seal pair, including movement push rod, seal receptacle, the movement push rod and sealing
Seat clearance fit, offers the first mounting groove and the second mounting groove being from top to bottom sequentially distributed on the inner wall of the seal receptacle,
V-shaped seal ring is installed in first mounting groove, inverted V type dustband is installed in second mounting groove, the movement pushes away
The outer wall of bar and V-shaped seal ring, inverted V type dustband closely against.
In the utility model preferred embodiment, seal receptacle, which is located on the inner wall of the first mounting groove and the second mounting groove, to be opened up
There is third mounting groove, is embedded with guide sleeve, the movement push rod and guide sleeve clearance fit at the third mounting groove.
In the utility model preferred embodiment, V-shaped seal ring is nitrile rubber, neoprene, EP rubbers, fluorine rubber
Sealing ring made of any one material in glue, silicon rubber.
In the utility model preferred embodiment, inverted V type dustband is nitrile rubber, neoprene, EP rubbers, fluorine rubber
Sealing ring made of any one material in glue, silicon rubber.
In the utility model preferred embodiment, guide sleeve is oil-containing Cu-based sliding bearing, utilizes sintered body on bearing
Lubricating oil of the porosity containing 10%-40% voluntarily feed lubrication push rod is oriented to push rod while protecting push rod, makes push rod
It is for linear motion.
Compared with prior art, the beneficial effects of the utility model are as follows:
(1) even if the inner ring for moving push rod and V-shaped seal ring in the utility model is worn, but due to the work of bleed pressure
For being allowed to further distending in the groove of V-shaped seal ring, the abrasion on the inside of V-shaped seal ring inner ring is compensated for, inside is prevented
Air leakage, to ensure that using effect and service life increase always in good sealing state on the inside of push rod and V-type circle
Add.
(2) when movement push rod acts on inverted V type dustband, the expansion of inverted V type dustband, the frictional force with movement push rod
Increase, can effectively strike off the dust on the outside of movement push rod, guarantees sealing effect and execution between movement push rod and seal receptacle
The service life of device push rod entirety.
(3) by the way that guide sleeve is arranged in seal receptacle in the utility model, guide sleeve plays sliding bearing to movement push rod, leads
It to supporting role, prevents the metal inner surface of movement push rod and seal receptacle from directly rubbing, guarantees that movement push rod has complete outer wall,
Maintain the sealing effect between sealing ring.
