Description

Injection valve for leaking stoppage

Technical Field

The invention belongs to the field of plugging, and particularly relates to an injection valve for plugging.

Background

In the process of plugging leakage of hazardous chemicals, the disposal of leakage parts such as flanges and valves often requires the injection of a sealant into the leakage point. In the glue injection process, an operator needs to use a high-pressure oil pump to inject the sealing material in the glue injection gun into the leakage position by hydraulic pressure, and an injection valve is usually needed to connect the glue injection gun and the leakage point. The existing injection valve uses a common thread cock, the axial position of the thread cock cannot be limited when the injection valve is used, when the thread cock is rotated too much, glue injection holes cannot be centered and communicated easily, an operator cannot observe and find the glue injection holes easily, and then plugging glue injection is influenced.

In order to achieve the purpose, the technical scheme of the invention is realized as follows:

the injection valve for plugging comprises a valve body, wherein a plug hole for placing a plug is formed in the top of the valve body, and a through hole is formed in the middle of a plug body of the plug;

the side of the valve body is provided with a positioning hole, the direction of the positioning hole is perpendicular to the direction of the plug hole, and is tangent to the plug hole, a positioning ring groove is arranged on the side wall of the plug body of the plug, one end of the positioning pin can be passed through the positioning hole on one side outside the valve body, and then enters the positioning hole on the other side after intersecting with the tangent line of the positioning ring groove.

Further, an internal thread is arranged at an outlet of the valve body and matched with an external thread of the screw rod, a central hole is axially formed in the screw rod, and the central hole is communicated with the outlet of the valve body.

Further, an external thread is arranged at the outlet of the valve body.

Furthermore, the top of the cock is a knob, a marking line is arranged on the knob, and the marking line is consistent with the axial direction of the through hole.

Further, the positioning ring groove is positioned right below or above the through hole.

The invention has the advantages and positive effects that: due to the adoption of the technical scheme, the utility model discloses an adopt between cock and the valve body can free rotation's sliding fit to utilize locating pin axial fixity, make the radial rotation of cock more nimble, guaranteed its axial position simultaneously and fixed, the injecting glue passageway centering of being convenient for communicates. Furthermore, the utility model discloses with the size increase in valve body exit, external dismantled and assembled screw rod has again realized having increased the intensity of valve body exit linkage department simultaneously to the connection of different specification screw holes, has reduced the cracked probability of threaded connection transition department in the use.

In addition, the three-dimensional dimensions of length, width and height should be included in the actual fabrication.

In the description of the present invention, it is to be understood that the terms "central," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in the orientation or positional relationship indicated in the drawings, which are merely for convenience in describing the invention and to simplify the description, and are not intended to indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and are therefore not to be construed as limiting the invention. Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the invention, the meaning of "a plurality" is two or more unless otherwise specified.

In the description of the invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted", "connected" and "connected" are to be construed broadly, e.g. as being fixed or detachable or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the creation of the present invention can be understood by those of ordinary skill in the art through specific situations.

As shown in figures 1, 2 and 3, the invention comprises a valve body 1, wherein a plug hole for placing a plug 2 is formed in the top of the valve body 1, and a through hole 8 is formed in the middle of a plug body of the plug 2; because the cock 2 blocks the inlet and outlet channels of the valve body 1, the inlet and outlet of the valve body 1 can be communicated by adjusting the position of the through hole 8;

the side of the valve body 1 is provided with a positioning hole 3, the direction of the positioning hole 3 is perpendicular to the direction of the plug hole, and is tangent to the plug hole, a positioning ring groove 4 is arranged on the side wall of the plug body of the plug 2, one end of a positioning pin 5 can be pulled through the positioning hole 3 on one side of the valve body 1, and the positioning hole 3 on the other side is inserted into the positioning hole 3 on the other side after being tangent to the positioning ring groove 4. The tap 2 is fixed in the tap hole of the valve body 1 so that the tap 2 can rotate radially but cannot move axially. When the cock 2 is fixed, the through hole 8 and the inlet and outlet channel of the valve body 1 are in the same line.

The outlet of the valve body 1 is simultaneously provided with internal and external threads, the internal threads are matched with the external threads of the screw rod 6, the screw rod 6 is axially provided with a center hole, and the center hole is communicated with the outlet of the valve body 1.
