Abstract
The invention discloses a fixed lubricating anti-collision valve rod which comprises a valve body, a valve rod body, valve decks and a balance seat. The valve rod body is installed in the valve body, and the two ends of the valve rod body penetrate out of the valve decks. The balance seat is arranged in the valve body and is penetrated by the valve rod body. The balance seat is internally provided with a balance rod. Sealing rings are arranged at the crossed parts of the valve rod body and the valve decks. A wearing ring is arranged on the outer surface of the valve rod body. Fixing blocks are further arranged in the parts, in the valve body, of the valve rod body and the valve decks. A sliding groove is formed in the upper surface of the balance seat, and an oil guide pipe is arranged above the sliding groove. One end of the oil guide pipe stretches in the sliding groove, and the other end of the oil guide pipe stretches out of the valve body and is sealed through a sealing cover. Trapezoidal anti-collision blocks are arranged between the valve rod body and the fixing blocks. According to the scheme, operation is more stable, and shaking during operation of a gate valve is reduced; the oil guide pipe in the sliding groove can guide lubricating oil into the valve body to achieve the lubricating function; and due to the trapezoidal anti-collision blocks, the phenomenon that the valve rod body collides with the fixing blocks during operation can be avoided, and the service life is prolonged.
Description
Technical field
The present invention relates to the crashproof valve rod of a kind of fixing lubrication, belong to plate valve technical field.
Background technique
Plate valve flashboard is pushed to outlet valve valve seat realization sealing by the pressure of valve inlet place medium, so firmly fasten plate valve not only can not play good seal action, on the contrary valve seat and flashboard are damaged to some extent, impact sealing, there is the phenomenon of valve rod shakiness simultaneously, be unfavorable for the running of gate valve.
Summary of the invention
For the technical problem of above-mentioned existence, the object of the invention is: propose and a kind ofly extend valve working life and the crashproof valve rod of fixing lubrication of good stability.
Technical solution of the present invention is achieved in that the crashproof valve rod of a kind of fixing lubrication, comprises valve body, valve rod, valve gap and balance base; Described valve rod is arranged on valve inner, and two ends pass valve gap; Described balance base is arranged on valve inner, and is passed by valve rod; Described balance base inside is provided with balancing pole; Described valve rod and valve gap intersection are provided with seal ring; Described stem exterior surface is provided with wear ring; Described valve rod and valve gap are also provided with fixed block in the part of valve inner; Described balance base upper surface is provided with sliding-groove; Oil guide pipe is provided with above described sliding-groove; Described oil guide pipe one end is stretched in sliding-groove, and the other end stretches out valve body and by seal cap sealing; Trapezoidal anticollison block is provided with between described valve rod and fixed block.
Preferably, described fixed block is provided with and holds out against spring.
Preferably, described valve body is made up of stainless steel.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
The crashproof valve rod of the fixing lubrication of one of the present invention, by installing balance base in valve body, valve rod can better be fixed under the support of balance base, and balance base and valve rod link together, more steady during running, reduce trembling when gate valve operates; Balance base upper surface is provided with sliding-groove, oil guide pipe is provided with above sliding-groove, oil guide pipe one end is stretched in sliding-groove, the other end stretches out valve body and by seal cap sealing, lubricant oil can be introduced in valve body by the oil guide pipe in sliding-groove, play lubrication, occur the situation of collision fixed block when trapezoidal anticollison block can prevent valve rod from operating, increase the service life.
Accompanying drawing explanation
