Abstract
The utility model discloses a high-viscosity low-fluidity liquid medium storage tank anti-freezing discharge valve comprising a cylindrical valve body, a valve bar, a piston, a handwheel, an oil outlet pipe and a flange disc. A seal disc is arranged on the inner side of one end of the valve body, a via hole provided inner screws is arranged at the center of the seal disc, and the outer side of the other end is provided with the flange disc; the piston is arranged in the inner cavity of the valve body, the valve bar is a screwed bar, one end of the valve bar is provided with the handwheel, the other end of the valve bar penetrates the via hole of the seal disc to connect to the piston, and the valve bar matches with the via hole through screws; the oil outlet pipe is arranged on one side of the middle of the valve body, and the inner cavity of the oil outlet pipe is communicated with the inner cavity of the valve body. The high-viscosity low-fluidity liquid medium storage tank anti-freezing discharge valve is reasonable in design, simple in structure, convenient to operate and high in practicality. When the valve is used in winter, medium is high in discharging speed, condensation medium rarely residues in the valve body after the medium is discharged, medium leakage and environment pollution caused by frozen valve body are reduced effectively or eliminated, and normal production of enterprises is guaranteed.
Description
Technical field
The utility model relates to a kind of liquid medium holding vessel escape cock, is specifically related to the poor antifreeze escape cock of liquid medium holding vessel of a kind of viscosity large fluidity.
Background technique
On the poor liquid medium holding vessel of dielectric viscosity large fluidity, all need to install escape cock, as oil field individual well oil storage tank, these escape cocks mostly are common valve, discharge medium rear valve body inside can remain cooling medium, while use in the winter time, media discharge speed is slow, and valve body is easily revealed medium by bursting by freezing, there is the phenomenon of befouling environment, having a strong impact on the normal production of enterprise.
Summary of the invention
The purpose of this utility model is exactly the defect existing for prior art, provides a kind of viscosity large fluidity the poor antifreeze escape cock of liquid medium holding vessel.
Its technological scheme is: the antifreeze escape cock of liquid medium holding vessel that viscosity large fluidity is poor, comprise valve body, valve rod, piston, handwheel, oil outlet tube and the flange plate of cylinder-like structure, inner side, described valve body one end is provided with shutoff dish, the centre of shutoff dish is provided with is with female via hole, its the other end outside is provided with flange plate, in the inner chamber of valve body, be provided with piston, described valve rod is threaded stem, one end of valve rod is provided with handwheel, the other end of valve rod is connected with piston through the via hole of shutoff dish, and the via hole of valve rod and shutoff dish passes through screw-thread fit; Described valve body middle part one side is provided with oil outlet tube, the inner chamber of oil outlet tube and the intracavity inter-connection of valve body.
Wherein, the inner circle of described via hole is provided with annular groove, is provided with seal ring in annular groove.Described annular groove is at least made as together.
The utility model compared with prior art, has the following advantages: reasonable in design, simple in structure, easy to operate, practical.While use in the winter time, media discharge speed is fast, and discharge medium rear valve body inside can not remain cooling medium, effectively alleviates or stopped valve body to be caused the generation of revealing medium, befouling environment phenomenon by bursting by freezing, has guaranteed the normal production of enterprise.
Accompanying drawing explanation
Fig. 1 is a kind of embodiment's of the utility model structural representation.
Embodiment
With reference to Fig. 1, the antifreeze escape cock of liquid medium holding vessel that a kind of viscosity large fluidity is poor, comprise the valve body 1 of cylinder-like structure, valve rod 2, piston 3, handwheel 4, oil outlet tube 6 and flange plate 7, described valve body 1 inner side, one end is provided with shutoff dish 5, the centre of shutoff dish 5 is provided with is with female via hole, its the other end outside is provided with flange plate 7, flange plate 7 is provided with mounting hole 8, in the inner chamber of valve body 1, be provided with piston 3, described valve rod 2 is threaded stem, one end of valve rod 2 is provided with handwheel 4, the other end of valve rod 2 is connected with piston 3 through the via hole of shutoff dish 5, valve rod 2 passes through screw-thread fit with the via hole of shutoff dish 5, when rotation hand wheel 4, valve rod 2 can drive piston 3 to move left and right, described valve body 1 middle part one side is provided with oil outlet tube 6, the intracavity inter-connection of the inner chamber of oil outlet tube 6 and valve body 1.Wherein, the inner circle of described via hole is provided with annular groove 9, in annular groove 9, is provided with seal ring.Described annular groove 9 is at least made as together.
When use, by the mounting hole 8 on flange plate 7, this device is fixedly mounted on to medium holding vessel, it is downward that oil outlet tube 6 obtains the mouth of pipe.While being rotated in the forward handwheel 4, via hole screw-internal thread fit on valve rod 2 and shutoff dish 5, drives piston 3 to move right, and in the time that piston 3 moves right to oil outlet tube 6 right side, escape cock cuts out; When counterrotating handwheel 4, via hole screw-internal thread fit on valve rod 2 and shutoff dish 5, drive piston 3 to be moved to the left, in the time that piston 3 is moved to the left to oil outlet tube 6 left side, escape cock is opened, due to the inner chamber of oil outlet tube 6 and the intracavity inter-connection of valve body 1, the inner chamber of valve body 1 is directly communicated with the inner chamber of medium holding vessel, and media discharge speed is fast; When escape cock cuts out, when piston 3 rests on the end of oil outlet tube 6 right sides, valve body 1, it is near medium holding vessel outer wall, and therefore, valve inner can not remain cooling medium.
The utility model is reasonable in design, simple in structure, easy to operate, practical.While use in the winter time, media discharge speed is fast, and discharge medium rear valve body inside can not remain cooling medium, effectively alleviates or stopped valve body to be caused the generation of revealing medium, befouling environment phenomenon by bursting by freezing, has guaranteed the normal production of enterprise.
