Abstract
The utility model discloses a check valve which comprises a valve body and a valve cap. An action valve plate is arranged in the valve body; a liquid outlet is formed on the valve body in a position corresponding to the action valve plate; and the liquid outlet is connected with a liquid discharge pipeline. By adopting the check valve, the hazard liquid between an outlet valve and the check valve can be discharged through the liquid outlet safely and effectively, and the action performance of the outlet valve can be checked without dismounting the check valve.
Description
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of safety check.
Background technique
Safety check is widely used in the fluid system, generally is installed in exit of pump and suffers the impact failure of water hammer with the protection water pump.In dangerous fluid application, when device maintenance,, between outlet valve and safety check, still can remain with a certain amount of dangerous liquid even closed outlet valve.The liquid of this part may bring danger and personal injury in actual job.
In addition, outlet valve under the situation of not dismantling safety check, is to be difficult to judge if can't close dead fault.
The model utility content
Technical problem to be solved in the utility model provides a kind of safety check, and it has the discharge opeing function.
For solving the problems of the technologies described above, the technical solution of the utility model safety check is:
Comprise valve body, valve gap, be provided with the action valve plate in the valve body; Position corresponding to the action valve plate on the described valve body is provided with liquid port.Described liquid port place connects Drainage pipe.
Described liquid port is arranged at the outlet end of action valve plate top.
The technique effect that the utility model can reach is:
The utility model can be by the liquid port dangerous liquid between exhaust outlet valve and the safety check safely and effectively.
The utility model can be checked the performance of outlet valve under the situation of not dismantling safety check.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the pipeline schematic representation that the utility model safety check is installed.
Description of reference numerals among the figure:
1 is safety check, and 2 is outlet valve,
11 is Drainage pipe, and 3 is water pump.
Embodiment
The utility model safety check comprises valve body, valve gap, is provided with the action valve plate in the valve body; Position (promptly move valve plate top outlet end) corresponding to the action valve plate on the valve body is provided with liquid port.
As shown in Figure 1, the utility model safety check 1 is installed between outlet valve 2 and the water pump 3, and the liquid port place of safety check 1 connects Drainage pipe 11.
The utlity model has the discharge opeing function, can stop the potential safety hazard in the maintenance process, increase work efficiency by the liquid port dangerous liquid between exhaust outlet valve 2 and the safety check 1 safely and effectively.
