Abstract

Provided is a lifting/lowering valve connecting member comprising an upper-part connecting member (1) and a lower-part connecting member (2); the upper-part connecting member (1) is divided into upper and lower sections, and the upper section is provided with an external thread (1-1); the lower section of the upper-part connecting member (1) has an outward projection (1-2), and the projection (1-2) is provided with a screw hole (3); the lower-part connecting member (2) is a straight pipe; the lower-part connecting member (2) is divided into upper and lower sections, and the inner diameter of the upper section of the lower-part connecting member (2) is consistent with the outer diameter dimension of the lower section of the upper-part connecting member (1); the upper section of the lower-part connecting member (2) is provided with a strip-shaped slot (2-1); the projection (1-2) of the lower section of the upper-part connecting member (1) may slide upward and downward in the strip-shaped slot (2-1) of the upper section of the lower-part connecting member (2); the lower section of the lower-part connecting member (2) is provided with an internal thread, thus resolving the problem, encountered when a valve connecting member is connected, of a pipe fitting being insufficiently long or excessively long.

Description

Lifting valve connector

Technical field

The invention relates to a lifting valve connection.

Background technique

The valve connecting piece is used to connect the valve and the pipe. The common valve connecting piece often encounters the condition that the pipe piece is not long enough or the pipe piece is too long when connecting, which is inconvenient for the use of the valve connecting piece.

Summary of the invention

It is an object of the present invention to provide a lift valve connector that addresses the above problems.

In order to achieve the above object, the technical solution of the present invention is to design a lifting valve connecting member, comprising an upper connecting member and a lower connecting member; the upper connecting member is a pipe bent from the middle; the upper connecting member is divided into The upper and lower sections are provided with external threads; the lower part of the upper connecting piece has a convex outward direction, and the protruding portion is provided with a screw hole; the lower connecting piece is a straight pipe; the lower connecting piece is divided into two upper and lower parts. a segment, the inner diameter of the upper portion of the lower connecting member and the outer diameter of the lower portion of the upper connecting member are uniform; the upper portion of the lower connecting member is provided with a strip-shaped groove, and the protrusion of the lower portion of the upper connecting member is at the upper portion of the lower connecting member The upper part of the upper connecting piece is provided with a plurality of screw holes; when the lower part of the upper connecting piece slides up and down in the strip groove, the screw hole on the protrusion has the opportunity to be on the lower connecting piece a screw hole corresponding to the outer wall; the lower portion of the lower connecting member is provided with an internal thread; the threaded tip of the internal thread to the bottom end of the thread is exactly the same as the wall thickness of the lower portion of the upper connecting member Cause.

The invention has the advantages and advantageous effects that the lifting valve connecting member of the invention solves the problem that the valve connecting member often encounters insufficient length of the pipe member or the pipe member is too long when connecting. When the invention is used, the height of the upper connecting member can be raised and lowered according to the actual situation. At this time, the protrusion of the lower end of the upper connecting member slides to a certain position in the strip groove of the upper portion of the lower connecting member, at this time, it is just raised. The screw hole is matched with a screw hole on the outer wall of the lower connecting member, and then the bolt is sequentially passed through the outer wall screw hole and the screw hole on the protrusion to fix the upper connecting member.

Among them, the upper connecting member 1, the external thread 1-1, the protrusion 1-2, the lower connecting member 2, the strip groove 2-1, the internal thread 2-2, and the screw hole 3.

detailed description

The specific embodiments of the present invention are further described below in conjunction with the drawings and embodiments. The following examples are only used The technical solutions of the present invention are more clearly illustrated, and the scope of protection of the present invention is not limited thereto.

Example:

A lifting valve connecting member comprises an upper connecting member 1 and a lower connecting member 2; the upper connecting member 1 is a pipe bent from the middle; the upper connecting member 1 is divided into upper and lower sections, and the upper section is provided with an outer portion Thread 1-1; the lower portion of the upper connecting member 1 has a protrusion 1-2 outwardly, and the protrusion 1-2 is provided with a screw hole 3; the lower connecting member 2 is a straight pipe; the lower connecting member 2 is divided into upper and lower two sections, the inner diameter of the upper section of the lower connecting member 2 and the outer diameter of the lower section of the upper connecting member 1 are the same; the upper connecting member 2 is provided with a strip groove 2-1 in the upper section, and the upper connecting member 1 The protrusion 1-2 of the lower stage can slide up and down in the strip groove 2-1 of the upper part of the lower connecting piece 2; the outer wall of the upper part of the lower connecting piece 2 is provided with a plurality of screw holes 3; the protrusion of the lower part of the upper connecting piece 1 When the 1-2 slides up and down in the strip groove 2-1, the screw hole 3 on the protrusion 1-2 has a chance to correspond to a certain screw hole 3 on the outer wall of the lower connecting member 2; the lower connecting member 2 The lower section is provided with an internal thread 2-2; the distance from the threaded end of the internal thread 2-2 to the bottom end of the thread is exactly the same as the wall thickness of the lower section of the upper connecting member 1

The above description is only a preferred embodiment of the present invention, and it should be noted that those skilled in the art can make several improvements and retouchings without departing from the technical principles of the present invention. It should also be considered as the scope of protection of the present invention.
