Description
Technical Field
The utility model relates to a self priming pump technical field, concretely relates to sealed effectual self priming pump body.
Background
When the existing self-priming pump is used, a water stop valve is usually installed, but under the long-time use, the problem that the water stop valve is misplaced or rocked is easily caused due to the impact of water flow on the water stop valve, so that the sealing effect is poor.
SUMMERY OF THE UTILITY MODEL
To the not enough of prior art existence, the utility model aims to provide a sealed effectual from inhaling the pump body.
In order to achieve the above purpose, the utility model provides a following technical scheme: the pump comprises a pump body and a front pipe body connected with the pump body, wherein a sealing cavity is formed between the pump body and the front pipe body, and a water stop valve is arranged in the sealing cavity;
the front pipe body is also internally provided with a limiting part for limiting the water stop valve.
Further, the water stop valve comprises a sealing ring, a sealing groove is formed in the sealing cavity, and a sealing ring matched with the sealing groove is arranged on the sealing ring.
Furthermore, a positioning groove matched with the sealing ring is arranged on the pump body.
Furthermore, the limiting part is connected with the front pipe body through threads.
Further, the one end that locating part and sealing washer contacted still covers has self-lubricating layer.
Further, the seal ring and the seal ring are integrally formed.
Contrast prior art not enough, the utility model provides a beneficial effect that technical scheme brought: when the sealing device is used, the water stop valve is located in the sealing cavity, and the problem that the water stop valve is rocked or misplaced under the condition of long-time use can be effectively avoided due to the existence of the limiting part, so that the sealing effect is enhanced, and the problem that the sealing effect is poor due to long-time use is avoided.

Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for purposes of illustration and explanation only and are not intended to limit the invention.
It should be noted that these drawings are simplified schematic views, and the basic structure of the present invention is described only in a schematic manner, and therefore, only the configuration related to the present invention is shown.
In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are used merely for convenience of description and for simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention. Furthermore, the terms "first", "second" and "first" 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" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, 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 present invention can be understood in specific cases to those skilled in the art.
The present invention is further described with reference to fig. 1-3.
A self-priming pump body with good sealing effect comprises a pump body and a front pipe body connected with the pump body, wherein a sealing cavity is formed between the pump body and the front pipe body, and a water stop valve is arranged in the sealing cavity;
a limiting part for limiting the water stop valve is also arranged in the front pipe body; when the sealing device is used, the water stop valve is located in the sealing cavity, and the problem that the water stop valve is rocked or misplaced under the condition of long-time use can be effectively avoided due to the existence of the limiting part, so that the sealing effect is enhanced, and the problem that the sealing effect is poor due to long-time use is avoided.
Further, the water stop valve includes the sealing washer, is equipped with the seal groove in the sealed cavity, be equipped with on the sealing washer with the sealing ring of seal groove looks adaptation, therefore the existence of sealing ring and seal groove makes to form multiple sealed, has further strengthened sealed effect.
Furthermore, be equipped with the constant head tank with sealing washer looks adaptation on the pump body, consequently make when the installation stagnant water valve, give for accurate to the installation of stagnant water valve, avoided because the installation inaccurate and the stagnant water valve that leads to rocks easily or the problem emergence of dislocation, avoided consequently causing the problem emergence of sealed effect variation.
Furthermore, the limiting piece and the front pipe body are connected through threads, and the limiting piece is cylindrical, so that the limiting effect on the water stop valve is better.
Further, the one end that locating part and sealing washer contacted has still covered the self-lubricating layer, and the self-lubricating layer is the polytetrafluoroethylene material, consequently can effectual reduction lie in the stagnant water valve when contacting, and the damage of consequently causing the stagnant water valve is avoided to the friction of locating part and stagnant water valve support.
Furthermore, the sealing ring and the sealing ring are integrally formed, so that the sealing ring is not easy to damage and the service life is prolonged.
The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and the skilled in the art can carry out the common changes and replacements within the technical solution of the present invention.
