Abstract
The invention relates to a high-pressure upper adjusting and cutting typed sealing ball valve, which is characterized in that a lower plane bearing is arranged in a round hole which is arranged at the bottom of a valve body; a lower lining is arranged on the lower plane bearing; two valve base components and an adjusting-typed valve ball are integrally assembled on the internal wedge-typed sealing surface of the valve body, thus forming an automatic compensation high-pressure sealing pair where an anti-torsion ring, an upper lining, a transmission shaft and an upper plane bearing are sequentially arranged; subsequently, the upper cover presses on the valve body which is provided with a graphite composite washer; a filler pad, graphite filler and filler pressing cover are sequentially arranged in an upper cover filler box and pressed tightly by nuts. The sealing ball valve can adjust and cut off the runway mediums under high pressures; unique high-pressure sealing system can ensure zero leakage of the valve body component in the chamber of a high-pressure valve; when the high pressure sealing performance is ensured, the flux can be adjusted; furthermore, wearable and unattackable alloy material can be surfacing-welded on the valve ball, thus ensuring the long-term effective operation of the valve.
Description
Technical field
The present invention relates to a kind of high pressure uploading adjustment cut-off type sealed ball valve, specifically be applied to realize adjusting and cut-out in the operating mode pipelines such as oil, chemical industry, electric power, metallurgy under the medium-pressure or high pressure, belong to the machinery valve industry field pipeline medium,
Background technique
Valve is the primary element of automation control in the whole industrial fluids power conduit system, realizes the control of pressure, flow velocity and the flow of convection cell, assurance system control safe, instant and effectively.And under condition of high voltage, how to realize the control of the multiple Flow characteristics of convection cell, be the place that needs the problem that solves in this field.Common ball valve is difficult to be implemented in the regulating and controlling of fluid flow flow characteristic under the high pressure complex working condition, is difficult to meet the needs of production.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, thereby a kind of high pressure uploading adjustment cut-off type sealed ball valve is provided, can guarantees the zero leakage of valve body assembly, when guaranteeing high-pressure tightness, realize the controllability of flow, and can guarantee the work that valve is permanently effective.
According to technological scheme provided by the invention, high pressure uploading adjustment cut-off type sealed ball valve comprises valve body, loam cake, transmission shaft, the adjustment type valve ball, valve component, feature is that the lower plane Bearing Installation is in the valve body bottom circular aperture, following lining is contained on the lower plane bearing, two valve components and adjustment type valve ball integral installation fit on the sealing surface of inclined wedge type in the valve body, form compensation high pressure sealing pair automatically, pack into successively and prevent turning round circle, last lining, transmission shaft reaches goes up plane bearing, loam cake is pressed on the valve body that the graphite Composition spacer is housed again, successively with Packing seat, graphite packing, Gland installs in the loam cake stuffing box, compresses with nut.
Build-up wear-resistant, corrosion resistant alloy material on the described adjustment type valve ball.
The adjusting window of described adjustment type valve ball is regulated flow, and described window comprises fast open form, equal percentage type or straight line type, and realizes cutting off function when closing fully.
Compared with the prior art the present invention has the following advantages:
The present invention is simple, compact and reasonable for structure; Can be implemented in the adjusting and the cut-out of convection current track media under the condition of high voltage; In the chamber of high pressure resistant valve body, unique high pressure sealing system guarantees the zero leakage of valve body assembly; The valve ball window size according to the adjusting requirement of operating mode, calculates through precise design simultaneously, when guaranteeing high-pressure tightness, realizes the controllability of flow; And build-up wear-resistant, corrosion resistant alloy material have guaranteed the work that valve is permanently effective on the valve ball.
