Abstract
The utility model relates to a multi-way valve which belongs to the technical field of metering and gathering of crude oil. The multi-way valve is composed of a valve body (6), a valve cap (5) and a valve core component (1), wherein, the valve core component (1) is composed of a valve core main body (16), an adjusting mechanism (22), a sealing ring (20) and an end cap (23). The transverse center of the valve core main body (16) is provided with a through hole, and the sealing ring (20) and a grease filling mechanism are arranged in the valve core main body (16). The utility model is characterized in that a grease filling hole (17) is arranged at the longitudinal upper part of the valve core main body (16), and a check valve (15) is arranged at the end part of the grease filling hole (17). The grease filling hole (17) is communicated with an annular space which is arranged between the valve core main body (16) and a valve seat (19), and a U-shaped sealing ring (18) is arranged in the annular space. When the sealing ring (18) of the multi-way valve is worn out, sealing grease is pumped into the grease filling hole (17) of the upper part of the valve core main body (16) by using a pump and the check valve (15). The sealing grease enters in the annular space and pushes the valve seat (19) and the sealing ring (20). The sealing performance between the sealing ring (20) and the valve body (6) can be restored, and the operation of adjusting the sealing ring (20) can be achieved without opening the valve cap (5) and the end cap (23).
Description
Technical field
The utility model is a kind of fluid that can realize many pipelines, is pooled to the multiple-way valve of a pipeline.Any one fluid in many pipelines of needs when shunting enters measuring apparatus, rotates the multiple-way valve spool, can realize distributing separately the fluid of required metering.Be mainly used in crude oil metering, gathering-transferring technology field.
Background technique
Now, in petroleum metering, the defeated process of collection, use a kind of multiple-way valve, it can be pooled to many mouthfuls of oil well produced crude oil in the pipeline.When any ducted fluid of needs, when measuring apparatus is sent in shunting, rotate the multiple-way valve spool, can realize that shunting enters measuring apparatus separately.This multiple-way valve has a plurality of inlets, a general export, a shunting outlet.It is made up of valve body, valve gap, spool.The spool fixed hole is arranged on the valve gap.Bearing support, upper bearing (metal) and last seal ring are arranged in the fixed hole.The fixed base that spool is arranged in the valve body has lower bearing and lower seal in the fixed base.The valve interior wall epimere is a cylindrical shape.Spool can rotate in cylinder, docks with single inlet respectively, realizes shunting separately.The spool of multiple-way valve is a critical component of realizing shunting.Spool is made up of spool main body, regulating mechanism, seal ring and end cap.The spool main body is similar to " ten " font, and spool main body transverse center is a through hole, and seal ring and seal ring regulating mechanism are installed in the hole, and there is end cap the end in hole.Behind sealing part abrasion, open end cap, the jackscrew of rotating and regulating mechanism makes seal ring compress inlet on the valve body, improves sealability.Spool main body lower end longitudinally has a split channel, and shunting crude oil laterally enters from valve base center hole, goes out from the vertical orifice flow of spool main body.The shortcoming of this spool is: the jackscrew of adjusting seal ring is in valve body, and each the adjustment when sealing must stop multiple-way valve work, opens valve gap, and opens end cap, could rotate jackscrew, adjusts seal ring.The method of this adjustment sealing delays crude oil transmission work.Have substantial oil in the valve body that is opened in addition, adjustment work is difficulty very.
Summary of the invention
The purpose of this utility model is: improve the regulating mechanism of seal ring, overcome ring wear after, adjust the difficulty of seal ring.Realize not beating valve gap, do not open end cap, do not stop crude oil transmission work, just can finish the work of adjusting seal ring.Promptly measure, collect under the defeated working state, carry out the sealing adjustment of multiple-way valve at multiple-way valve.
The utility model is achieved in that the greasing hole on the spool main body, there is one-way valve the end of spool main body.The greasing hole is communicated with the annular space between spool main body and the valve seat, and seal ring is arranged in the annular space, forms an annular oil hydraulic cylinder.The power transmission cover is arranged at seal ring top.
Effect of the present utility model is tangible.After the seal ring of multiple-way valve used and weares and teares, the sealability of seal ring and valve body reduced.The utility model can adopt pump, by single current seal gease is injected greasing hole, spool main body upper end.The greasing hole is communicated with the annular space between spool main body and the valve seat, and seal gease injects in the annular space.The annular space internal pressure increases, and promotes valve seat and seal ring.Sealability between seal ring and the valve body is restored.Valve gap and end cap needn't be opened, under multiple-way valve metering, the defeated working state of collection, just the adjustment seal ring can be finished.
