Abstract
The utility model relates to a sewage drainage device. A body is a right-angle tee pipe; one end of a straight pipe of the tee pipe is plugged by a valve bonnet and sealed by a sealing ring; a bearing is mounted inside the valve bonnet; a valve rod penetrates through the center of the valve bonnet; the inner end of the pipe is connected with the bearing; one end of an intermediate rod is connected with the valve rod; the other end of the intermediate rod is connected with a valve core positioned at the connecting position of a straight pipe at the straight outlet end with a branch pipe; a through hole communicated with the branch pipe is arranged on the valve core connected with a valve seat in an end surface sealing manner; a through hole communicated with the straight pipe is arranged on the valve seat; a spring is mounted between the inner wall of the valve bonnet and the outer wall of the valve rod; and a flange is connected onto the outer wall of the end opening of the branch pipe. The sewage drainage device has the advantages of simple and compact structure, large bearing pressure, no vibration in work, capability of preventing scouring, abrasion resistance, long service life and the like, and has the functions of regulating flow and stopping.
Description
Technical field
The utility model relates to a kind of drainage device that is used for the oil gas field working medium.
Background technique
Drainage device is mainly used in oil gas field working medium such as the transfer line such as crude oil, rock gas and sewage, particularly contains the conveying valve member of pipelines such as impurity such as silt particle in the medium, has regulating flow and ends function.
In the oil gas field production process, exist a large amount of pipeline conveying processes, thereby the safety of transfer line is most important.Because underground native gas, former wet goods contain certain impurity such as silt particle, in high pressure and quick course of conveying, silt particle produces impact wear to transfer line and equipment, shortens its working life greatly, seriously jeopardizes the person and property safety.
The model utility content
The purpose of this utility model is a kind of drainage device of design, can protection against erosion, wear-resistant, and improve working life, and have regulating flow and by function.This product structure is simple compact, bear that pressure is big, work is shockproof, use advantages such as mission is long.
Drainage device described in the utility model is divided into two kinds of right-angle type and straight-through types; The right-angle type structure is made up of flange, spring, intermediate bar, bearing, seal ring, valve rod, bonnet, main body, spool, valve seat;
Main body is a right-angle type three-way pipe, and straight tube one end of three-way pipe is blocked by bonnet, the seal ring sealing; Bearing is contained in the bonnet, and valve rod passes the bonnet center, and pipe is inner to be connected with bearing; Intermediate bar one end is connected with valve rod, and the other end is connected with spool; Spool is positioned at the straight tube and the arm joint of straight tube outlet end, spool is provided with the through hole with arm UNICOM, and spool is that end face seal is connected with valve seat, and valve seat is provided with the through hole with straight tube UNICOM, spring is installed between bonnet inwall and the valve rod outer wall, and flange is connected on the arm port outer wall.
Straight-through structure is made up of flange, spring, bearing, seal ring, valve rod, bonnet, main body, spool, valve seat; Main body is one by the three-way pipe of being responsible for and arm constitutes, and the two ends mouth of pipe of managing the joint in being responsible in pipe and the arm misplaces with arm and is connected; Bonnet is positioned at the opening end shutoff port of arm, the seal ring sealing; Bearing is contained in the bonnet, and valve rod passes the bonnet center, and pipe is inner to be connected with spool by bearing; Spool and valve seat with the person in charge that arm is connected between the mouth of pipe of pipe two ends, spool and valve seat are end face seal, the through hole of pipe entrance point UNICOM in spool is provided with and is responsible for, the through hole of pipe outlet end UNICOM in valve seat is provided with and is responsible for, spring is installed in valve rod and spool joint, and flange is connected to be responsible on the port outer wall.
Working principle is as follows:
The right-angle type structure: actuate valve stem drives the intermediate bar transmission, and valve core rotation aligns through hole on the spool and the through hole on the valve seat or staggers, valve opening or close.
Straight-through structure: actuate valve stem, valve core rotation, spool bore and valve seat orifice align or stagger, valve opening or close.
Though the utility model design is primarily aimed at petroleum gas, is fit to other gases or liquid.Not only be applicable to petroleum and petrochemical industry, also can be widely used in other industry.Its main feature has:
1, sealing is reliable: spool and valve base chamber are end face seal, and big more its of working pressure seals tightly more.
2, anti-washing away: key positions such as spool valve seat adopt wear-resisting, resistant to elevated temperatures new ceramic material, and whole service life has obtained large increase.
3, multiple driving mode: the open and close of valve can adopt electronic, surge, pneumatic or manual, electromechanical is realized automation.
4, regulate and by function: because key components and parts has adopted wear-resisting new ceramic material---abrasion resistance can be good, and valve can be opened size arbitrarily and control flow area, thereby realize the effect of regulating flow and ending.
5, Placement: flange, screw thread and three kinds of Placements of welding.
