Abstract
The invention provides a high-wear-resistance turbine butterfly valve. The high-wear-resistance turbine butterfly valve comprises a valve body, a valve plate, a valve deck, a turbine head, a butterfly plate and a valve shaft. The butterfly plate is mounted in the valve body through the valve shaft. A sealing ring is arranged on the butterfly plate. A steel mesh layer is embedded in the sealing ring in the circumferential direction. The valve deck is fixed to the upper end of the valve body. The turbine head is fixed to the upper end of the valve deck. Wear-resistant blocks are arranged at the upper end and the lower end of the inner side of the valve body correspondingly, wherein the wear-resistant block fixed to the upper end of the inner side of the valve body is connected with a downward pressing spring connected with the valve deck, and the wear-resistant block fixed to the lower end of the inner side of the valve body is connected with an upward pressing spring connected with the valve body. Compared with the prior art, the high-wear-resistance turbine butterfly valve has the remarkable advantages and beneficial effects that the strength and toughness of the sealing ring are improved through the steel mesh layer, and the wear resisting performance of the sealing ring is enhanced; besides, the wear-resistant blocks are arranged in the positions which can be worn most easily; and when the wear-resistant blocks are worn, the springs can push the wear-resistant blocks to move towards the butterfly plate so as to prevent leakage caused by wear.
Description
Technical field
The present invention relates to valve manufacture association area, more particularly, to a kind of high abrasion turbine butterfly valve.
Background technology
Butterfly valve refers to that closure member (flap or butterfly plate) is disk, rotates to reach one kind of open and close around valve shaft
Valve, acts primarily as cut-out and throttling action on pipeline.Butterfly valve opening and closing element is a discoidal butterfly plate, around its own in valve body
Axis rotation, thus reach open and close or adjust purpose.Current butterfly valve is in the moment cut out and open, the sealing pair of valve
Huge frictional force can be produced, so that sealing pair is destroyed quickly, so that the life-span of sealing pair is reduced；If increased between sealing pair
Gap is although frictional force can be reduced, but the seal pressure of valve does not reach, and frequently can lead to valve leaks, and serious meeting leads to
The generation of major accident.
Content of the invention
Problem to be solved by this invention is to overcome the deficiencies in the prior art, provides and a kind of is easy to the magnetic that nail polish bottle picks and places
Property nail polish bottle fixed mount.
The present invention solves its technical problem and takes technical scheme below to realize:
A kind of high abrasion turbine butterfly valve, including valve body, valve gap, turbine head, butterfly plate, valve shaft, described butterfly plate is installed on by valve shaft
In described valve body, butterfly plate is provided with sealing ring, and described sealing ring center is provided with the steel stranded by a plurality of stainless steel filament
Tow, described sealing ring is that inside is embedded with circumferentially disposed steel screen layer, and the upper end of described valve body is fixed with valve gap, described valve
The upper end of lid is fixed with turbine head, and the upper and lower ends inside described valve body are equipped with wear-resistant block, are wherein fixed on inside valve body
The wear-resistant block at end is connected with the lower pressing spring being connected with valve gap, and the wear-resistant block being fixed on valve body inside lower end is connected with and valve body phase
Upper pressing spring even.
Further, described steel screen layer is formed by braided steel wire.
Further, described steel screen layer is wrapped with nylon string course.
Further, it is provided with sealing packed layer between described valve body and described wear-resistant block.
The present invention compared with prior art has significant advantage and beneficial effect: steel screen layer improves the strong of sealing ring
Degree and toughness, strengthen its wear resistance；In addition, being provided with wear-resistant block at position the most easy to wear, when wear-resistant block is worn
When, described spring can promote described wear-resistant block to move to butterfly plate direction, prevent the leakage causing because of abrasion, extend butterfly valve
Service life.
