Description

Discharging tank bottom fluorine lining valve

Technical Field

The utility model relates to the technical field of valves, in particular to a fluorine-lined valve for a bottom of a discharge tank.

Background

The valve is a common valve product for controlling the on-off of a pipeline system, is widely applied to a liquid discharge tank, and is provided with a flashboard, a valve rod, a hand wheel and other structures, wherein the flashboard is used for closing and opening a fluid channel.

The valve rod is used for being connected with the flashboard to drive the flashboard to move so as to change the opening and closing states of the flashboard, and the hand wheel is connected with the valve rod, so that the valve rod moves under the drive of the hand wheel to control the movement of the flashboard.

The existing valve is characterized in that the flashboard is frequently lifted and is contacted with liquid in a pipeline, so that the liquid is easy to corrode the flashboard, and when the flashboard is driven by the hand wheel to open the valve, acting force generated between the flashboard and the inner wall of the valve body can cause damage to the inner wall of the valve body and the flashboard, so that the service life of the valve is influenced, and further improvement is needed on the basis.

In order to achieve the above purpose, the present utility model is realized by the following technical scheme: the utility model provides a ejection of compact tank bottom lining fluorine valve, includes valve body, flashboard, valve rod, the inside fluid passage that is provided with of valve body and the buffering cavity that is used for placing the flashboard, the valve rod stretches into in the buffering cavity and is connected with the flashboard, the valve rod is external to have the hand wheel, the fluid passage surface is provided with the tetrafluoro lining, the flashboard is made by the tetrafluoro material, the fluid passage is provided with the buffering recess in its bottom, the inside of buffering recess is connected with the tetrafluoro board through several spring column, the outer edge of tetrafluoro board is provided with the sealing washer that contacts with buffering recess inner wall.

Further, the valve rod is connected with the flashboard through a thread structure.

Further, the number of the spring columns arranged in the buffer groove is at least three.

Further, the valve body is provided with flanges connected with the discharge tank at two opposite sides of the fluid channel.

Further, a clamping groove is formed in the outer edge surface of the tetrafluoro plate, and the sealing ring is plugged in the clamping groove and is contacted with the buffer groove.

Further, the buffer groove position is directly opposite to the buffer chamber position.

The utility model has the following beneficial effects:

according to the utility model, the polytetrafluoroethylene lining is arranged in the fluid channel, the flashboard made of polytetrafluoroethylene is arranged in the buffer cavity, corrosive fluid can be prevented from corroding the fluid channel and the flashboard, the buffer groove is arranged on the fluid channel, the spring column is arranged in the buffer groove to be matched with the polytetrafluoroethylene plate, the flashboard can be prevented from being damaged by lifting or falling or the valve body is prevented from being damaged, and compared with the traditional fluorine lining valve, the valve has relatively long service life and strong practicability.

Drawings

The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the disclosure and together with the description, serve to explain the principles of the disclosure.

FIG. 1 is a schematic diagram of the overall structure of the present disclosure;

fig. 2 is a schematic side view of a tetrafluoro plate and spring post of the present disclosure.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.

Examples

Referring to fig. 1 and 2, a fluorine-lined valve for a discharge tank bottom comprises a valve body 10, a flashboard 20 and a valve rod 30, wherein a fluid channel 11 and a buffer chamber 12 for placing the flashboard are arranged in the valve body, the valve rod extends into the buffer chamber and is connected with the flashboard, when in actual use, the valve rod is connected with the flashboard through a threaded structure, a hand wheel 90 is externally connected with the valve rod, and when an operator operates the hand wheel, the valve rod can realize lifting movement, so that the fluid channel is closed or opened; the surface of the fluid channel is provided with a tetrafluoro lining 40, the flashboard is made of tetrafluoro material, the bottom of the fluid channel is provided with a buffer groove 50, the position of the buffer groove is opposite to that of the buffer chamber, the inner part of the buffer groove is connected with a tetrafluoro plate 70 through a plurality of spring columns 60, the number of the spring columns arranged in the buffer groove is at least three, so as to ensure the lifting stability of the tetrafluoro plate in the buffer groove, and the outer edge of the tetrafluoro plate is provided with a sealing ring 80 contacted with the inner wall of the buffer groove.

In addition to the above, the valve body is provided with flanges 13 connected with the discharge tank on two opposite sides of the fluid channel, and correspondingly, the bottom of the discharge tank used in the utility model is provided with a discharge port, and the discharge port is provided with a flange (adapted to the flange structure on the valve body).

As a preferred embodiment of the present utility model, the outer edge surface of the tetrafluoro plate is provided with a clamping groove 71, the sealing ring is plugged in the clamping groove and contacts with the buffer groove, and by providing the clamping groove on the tetrafluoro plate, the sealing ring can be prevented from falling off the tetrafluoro plate, and the fluid in the fluid channel will not flow into the buffer groove.
