Description

High-performance fluorine-lined gate valve

Technical Field

The utility model relates to a gate valve technical field especially relates to a high performance lining fluorine gate valve.

Background

The gate valve is a shutter, the movement direction of the shutter is vertical to the fluid direction, and the gate valve can only be fully opened and fully closed and cannot be adjusted and throttled. The gate valve seals through disk seat and flashboard contact, and the sealed face can build up welding metal material in order to increase the wearability usually, and the flashboard has rigidity flashboard and elasticity flashboard, and according to the difference of flashboard, the gate valve divide into rigidity gate valve and elasticity gate valve.

Traditional gate valve uses V type PTFE filler assembly to reach the sealing performance of product, but the effect is limited, and sealed effect still remains to be improved, consequently needs to improve its filler assembly mode for under the condition that has pressure in inside, the sealed effect of valve is better.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a: in order to solve the above problems, a high performance fluorine lined gate valve has been proposed.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a high performance lining fluorine gate valve, includes valve body and last valve stem, be equipped with flashboard and valve gap on the valve body, be equipped with tapered packing subassembly one and tapered packing subassembly two in the sealed face on the valve gap, be equipped with gland on tapered packing subassembly one and the tapered packing subassembly two, the gland is last to be equipped with the connecting block.

Preferably, the first conical packing component and the second conical packing component are respectively composed of inner and outer conical PTFE and a stainless steel sealing pressing ring.

Preferably, the connecting block is of a circular ring structure, the inner circle of the connecting block is in threaded connection with the upper valve rod, and the outer circle of the connecting block is in sliding connection with the inside of the valve cover.

Preferably, the packing gland is slidably connected with the interior of the valve cover, and an elastic rubber ring is arranged on the contact surface of the upper surface of the packing gland and the connecting block.

Preferably, the surface of the valve body is provided with a wear-resistant layer.

To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:

this application is through the sealing performance in order to ensure the product, prevent outer hourglass, reduce the assembly degree of difficulty, change former V type PTFE filler subassembly into interior, the sealed clamping ring of PTFE + stainless steel of outer cone type, the high-speed sealing performance of reuse gland, ensure under the inside pressurized condition, the sealed effect of valve is more and more good, reduce the possibility of product outer leakage, because only a set of tetrafluoro cone type packs, change and need multistage V type to pack the structure that just can guarantee sealed effect originally, the possibility of producing the mistake when having reduced the assembly, the assembly efficiency is promoted, save a large amount of manpowers and material resources cost.
