It is main on pipeline to play cut-out and throttling action.Butterfly valve opening and closing element is a discoidal butterfly plate, around the axle of its own in valve body
Line rotates, so as to reach the purpose for opening and closing or adjusting.
Traditional butterfly valve includes valve body, valve rod and flap, and runner is provided with valve body, and valve rod drives flap to rotate and realizes stream
The circulation and cut-out in road, valve rod rotation is arranged at valve body and a part of contact surface has friction, because medium is rotten after long-time
Erosion or itself abrasion, cause stem outer circumference roughness to increase, so that the convenience that valve rod is operated is hindered, additionally, the new butterfly installed
There are machined burrs between the valve body and valve rod of valve, the part machined burrs can also increase the abrasion of stem outer circumference.
The content of the invention
In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of profit certainly for increasing the service life
Sliding butterfly valve.
To achieve the above object, the utility model provides following technical scheme：It is described including valve body, valve rod and flap
Valve body in be provided with runner, described valve rod drives flap to rotate the circulation and cut-out for realizing runner, is set in described valve body
It is equipped with the rotation chamber circumferentially rotated for valve rod, it is characterised in that：The storage chamber for placing lubricant, institute are provided with described valve body
The storage chamber stated be provided with the supply port of extraneous UNICOM and with the spout for rotating chamber UNICOM, be provided with described storage chamber by
The stripper plate that lubricant is extruded to spout, is provided with reducing motor outside described valve body, described reducing motor drives and is provided with
Storage chamber and the drive rod coordinated with stripper plate screw thread are extended to, described storage chamber is provided with positioned at supply port and only allow lubrication
The one way component that agent enters.
By using above-mentioned technical proposal, stripper plate extrudes the lubricant in storage chamber from spout to valve rod, it is to avoid tear open
Unload valve rod to safeguard valve rod, and compare from gap and clamp-on lubricant, lubrication more comprehensively, is at the uniform velocity pushed by reducing motor
Lubricant, further increases the uniformity of lubrication, when lubricant starvation, can be filled into from supply port, because supply port is set
There is one way component, it is to avoid lubricating oil is revealed when idle.
The utility model is further arranged to：Described one way component includes steel ball, steel ball spring and steel ball track, described
Steel ball track and supply port be oppositely arranged and supply steel ball sliding, described steel ball spring one end is fixed in storage chamber, another
End resets steel ball to supply port.
By using above-mentioned technical proposal, steel ball can be extruded to inner side when lubricant clamp-ons supply port, lubricant is smooth
Into storage chamber, and after the completion of supplementing, steel ball spring resets steel ball, realizes the sealing of supply port, it is to avoid leakage of lubricant.
The utility model is further arranged to：Described storage chamber is provided with stripper plate to the limit matched somebody with somebody along spout side is located at
Position block.
By using above-mentioned technical proposal, limited block is set up, it is to avoid because stripper plate is fitted spout completely, atmospheric pressure effect
Stripper plate is set to be difficult to return to initial position, so as to increase practicality.
The utility model is further arranged to：Several nail collection slots are offered in described rotation cavity wall, the nail collection slot cuts
Face is V-shaped and opening of V-shape is towards valve rod.
By using above-mentioned technical proposal, lubricant is sprayed from spout when using for the first time, rotary valve rod repeatedly, valve rod with
The scrap produced by burr between valve body can be piled up in nail collection slot, so as to reduce the part scrap to caused by stem outer circumference
Abrasion.
The utility model is further described with reference to the accompanying drawings and detailed description.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model specific embodiment；
Fig. 2 is the enlarged drawing of A in Fig. 1.
Specific embodiment
As shown in Fig. 1-Fig. 2, the utility model discloses a kind of self-lubricating butterfly valve, including valve body 1, valve rod 2 and flap 3,
Runner 11 is provided with valve body 1, valve rod 2 drives flap 3 to rotate the circulation and cut-out for realizing runner 11, confession is provided with valve body 1
The storage chamber 12 for placing lubricant is provided with the rotation chamber that valve rod 2 is circumferentially rotated, valve body 1, storage chamber 12 is provided with and the external world
The supply port 123 of UNICOM and the spout 121 with rotation chamber UNICOM, are provided with storage chamber 12 and lubricant are extruded to spout 121
Stripper plate 122, be provided with reducing motor 4 outside valve body 1, reducing motor 4 drive be provided with extend to storage chamber 12 and with extruding
The drive rod 41 that the screw thread of plate 122 coordinates, storage chamber 12 is located at supply port 123 and is provided with the unidirectional set for only allowing lubricant to enter
