Abstract
The utility model discloses an axial-flow type check valve body and disk seat support ring connection structure, including valve body, disk seat support ring, bolt, disk seat and filler, the disk seat is installed to the valve body inboard, install the filler between disk seat outer lane and the valve body inner wall, the port of valve body is located disk seat one side and has the disk seat support ring through threaded connection, disk seat support ring outer lane is through a plurality of bolts and valve body fixed connection. The utility model discloses under the condition that does not change valve body and disk seat support ring structure, can be to disk seat support ring fixed connection on the valve body, avoided the disk seat support ring when the higher operating mode of pressure, because medium backpressure is big, including the medium strikes, probably cause the screw thread not hard up, cause the valve to leak, the problem that the disk seat drops even can guarantee the reliability that disk seat and valve body are connected, extension valve life dismantles simultaneously and installs simple and conveniently, the utility model has the advantages of simple and reasonable structure, the installation with dismantle conveniently, the cost of manufacture is low, the practicality is strong.
Description
Technical Field
The utility model relates to a valve field specifically relates to an axial-flow type check valve body and disk seat support ring connection structure.
Background
The axial flow type check valve has the functions of a common check valve, and is also provided with a damping spring, the combined valve seat sealing structure with the hard sealing belt and the soft sealing has the effects of noise elimination and damping, and is convenient for a user to overhaul on site, and the unique axial flow shuttle type structure has the advantages of small flow resistance, large flow coefficient, small overall dimension and the like, and is a preferred valve for domestic and foreign oil and gas gathering and transportation pipe network systems, particularly oil transportation pump outlets; the valve seat support of axial-flow check valve is through threaded connection to the valve body usually, and this kind of simple structure, it is convenient to dismantle, but when being used for the higher operating mode of pressure, because medium backpressure is big, in addition the medium strikes, may cause the screw thread to become flexible, causes the valve leakage, and the valve seat drops even, for this reason, we propose axial-flow check valve body and valve seat support ring connection structure.
Disclosure of Invention
The utility model aims to solve the technical problem that an axial flow check valve body and disk seat support ring connection structure is provided, the disk seat that has solved current axial flow check valve supports through threaded connection to the valve body on, this kind of simple structure, and it is convenient to dismantle, but when being used for the higher operating mode of pressure, because medium backpressure is big, in addition medium impact, can cause the screw thread not hard up, causes the valve to leak, the problem that the disk seat drops even.
In order to solve the technical problem, the utility model provides a following technical scheme: axial-flow type check valve body and disk seat support ring connection structure, including valve body, disk seat support ring, bolt, disk seat and filler, the disk seat is installed to the valve body inboard, install the filler between disk seat outer lane and the valve body inner wall, the port of valve body is located disk seat one side and has the disk seat support ring through threaded connection, disk seat support ring outer lane is through a plurality of bolts and valve body fixed connection.
On the basis of the scheme, the valve seat is in sliding fit with the valve body.
On the basis of the scheme, the filler is respectively in sealing fit with the valve seat and the valve body.
On the basis of the scheme, the inner end of the valve seat support ring is pressed on the end head of the valve seat.
Compared with the prior art, the utility model beneficial effect who has is: axial-flow type check valve body and disk seat support ring connection structure adopts new structure, the connection structure who supports current axial-flow type check valve body and disk seat improves, under the condition that does not change valve body and disk seat support ring structure, can be to disk seat support ring fixed connection on the valve body, avoided the disk seat support ring when the higher operating mode of pressure, because medium backpressure is big, including the medium impact, probably cause the screw thread not hard up, cause the valve to leak, the problem that the disk seat drops even, can guarantee the reliability that disk seat and valve body are connected, extension valve life, dismantle simultaneously with the installation simple and convenient, the utility model has the advantages of simple and reasonable structure, the installation is convenient with the dismantlement, the cost of manufacture is low, the practicality is strong.
