Abstract
The utility model discloses a numerical control grease sealed multi-way valve, which comprises a valve cover, a valve body and a valve core. The valve core comprises a valve core main body and a valve seat; the valve core main body is provided with a crude oil distribution hole and a distribution channel; the valve seat is arranged in the crude oil distribution hole; the central hole of the valve seat is communicated with the crude oil distribution hole; a sealing piece for sealing the end of the crude oil distribution hole and an oil inlet is pressed against the front end part of the valve seat; a force transfer sleeve is arranged on the rear part of the valve seat; and a grease injection port is formed on the upper part of the valve core main body and is communicated with a sealing annular space between the valve core main body and the valve seat. In the numerical control grease sealed multi-way valve, sealing grease can be injected into the grease injection port at the upper end of the valve core main body and enters the sealing annular space between the valve core main body and the valve seat to push the valve seat so as to push the sealing piece to move forwards. Therefore, the sealing performance between the sealing piece and the valve body is recovered.
Description
Technical field
The utility model relates to a kind of numerical control grease seal formula multiple-way valve.
Background technique
Because multiple-way valve can be pooled to many mouthfuls of oil well produced crude oil in the pipeline, thereby be widely used in petroleum metering, the defeated process of collection.This multiple-way valve has a plurality of inlets, a general export, a shunting outlet.Rotate in valve body by spool, dock with single inlet respectively, realize shunting separately.
The spool of multiple-way valve is a critical component of realizing shunting.Be provided with Sealing with the inlet portion of connecting on it, in long-time using process, Sealing can wear and tear gradually.In the prior art, be provided with the jackscrew that leans mutually with Sealing in the spool, behind sealing part abrasion, open the end cap of spool, the jackscrew of rotating and regulating mechanism travels forward further to be pressed to the inlet on the valve body Sealing, improves sealability.Because the jackscrew of adjusting Sealing must stop the work of multiple-way valve when adjusting Sealing in valve body, open valve gap, and open end cap, could rotate jackscrew at every turn, adjust Sealing.The method of this adjustment sealing delays crude oil transmission work, has substantial oil in the valve body that is opened in addition, and adjustment work is difficulty very.
The model utility content
At the problem that prior art exists, the purpose of this utility model is to provide a kind of structure through improving, and simplifies the numerical control grease seal formula multiple-way valve of adjusting sealing part works.
For achieving the above object, the utility model numerical control grease seal formula multiple-way valve, comprise valve gap, valve body and spool, wherein, spool comprises spool main body and valve seat, and the spool main body is provided with crude oil tap hole and split channel, valve seat is arranged in the crude oil tap hole, and the center hole of valve seat communicates with the crude oil tap hole, and the front end of valve seat leans and is provided with the nose end that makes the crude oil tap hole and the oil-feed inlet Sealing of sealing mutually, and the rear portion of valve seat is provided with the power transmission cover; The top of spool main body is provided with the greasing hole, and this greasing hole is communicated with the annular seal space between spool main body and the valve seat.
Further, the port in described greasing hole is provided with one-way valve, and the mounting hole of one-way valve and greasing hole intersect vertically.
Further, described greasing hole comprises vertical hole and the transverse holes that is provided with on the spool main body, and vertically hole and transverse holes communicate, and the nose end in greasing hole adopts screw and copper washer sealing.
Further, the annular seal space place between described spool main body and the valve seat is provided with seal ring.
The utility model numerical control grease seal formula multiple-way valve, seal gease can be injected greasing hole, spool main body upper end, make seal gease enter annular seal space between spool main body and the valve seat, to promote valve seat, and then promote Sealing and travel forward, make that the sealability between Sealing and the valve body is restored.
