Abstract
The utility model discloses a valve body of a check valve. The valve body comprises a water inlet section and a main valve body, a water outlet is arranged at the other end of the main valve body, a valve cover is arranged at the upper end of the main valve body, and mounting holes are arranged on two sides of the upper end of the main valve body. The valve body can prevent backflow of media, reverse rotation of a pump and a driving motor and discharge of container media, and can also be used for a pipeline for supplying power to an auxiliary system, wherein the pressure of the auxiliary system possibly rises to exceed system pressure. Working efficiency is improved, and the valve body is convenient to use.
Description
Technical field
The utility model relates to valve field, belongs to more specifically a kind of valve body of safety check.
Background technique
The valve that the valve body of safety check can stop fluid to flow backwards automatically, the flap of the valve body of safety check is opened under fluid pressure action, and fluid flows to outlet side from suction side.When suction side pressure is lower than outlet side, prevent that medium from flowing backwards, preventing pump and drive motor counter-rotating, and the releasing of vessel media, the valve body of safety check also can be used for may rising to the auxiliary system of pressing above system to wherein pressure to be provided on the pipeline of supply.Existing technical pattern is simple, and the water hammer performance is bad, and fabricating cost is high, has reduced working efficiency.
The model utility content
The purpose of this utility model provides a kind of valve body of safety check, reasonable in design, and good stability prevents that medium from flowing backwards, preventing pump and drive motor counter-rotating, and the releasing of vessel media, and has improved working efficiency, it is also convenient to use.
The technical solution of the utility model is as follows:
A kind of valve body of safety check includes inlet segment, valve body body, and the other end of described valve body body is water outlet, and the upper end of valve body body is provided with valve gap, and the both sides, upper end of valve body body have mounting hole.
Described mounting hole has internal thread segment.
Described rocking bar upper end is U-shaped scaffold, has the mounting hole that matches with valve rod in the U-shaped scaffold.
The utility model can prevent that medium from flowing backwards, preventing pump and drive motor counter-rotating, and the releasing of vessel media, the valve body of safety check also can be used for may rising to the auxiliary system of pressing above system to wherein pressure to be provided on the pipeline of supply, has improved working efficiency, and it is also convenient to use.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Referring to accompanying drawing, a kind of valve body of safety check includes inlet segment 1, valve body body 2, and the other end of valve body body 2 is water outlet, and the upper end of valve body body 2 is provided with valve gap 4, and the both sides, upper end of valve body body 2 have mounting hole 3, and mounting hole 3 has internal thread segment 5.
Claims (2)
1. the valve body of a safety check includes inlet segment, valve body body, it is characterized in that: the other end of described valve body body is water outlet, and the upper end of valve body body is provided with valve gap, and the both sides, upper end of valve body body have mounting hole.
2. the valve body of a kind of safety check according to claim 1, it is characterized in that: described mounting hole has internal thread segment.
