Abstract
The utility model discloses a single disc swing check valve for a slurry pump system. The single disc swing check valve comprises a valve plate (2) and a valve core (1), wherein 1-4 through holes (3) are formed in the valve plate. The single disc swing check valve disclosed by the utility model has the benefits as follows: the pressure of a pipeline is reduced through the through holes formed in the valve plate and used for releasing pressure; and as the valve core is wrapped in a rubber housing, the service life of the single disc swing check valve is prolonged.
Description
Technical field
The utility model relates to safety check, relates in particular to a kind of single-lobe Swing check valve.
Background technique
Safety check claims again one-way valve or check valve, and its effect is to prevent that the medium in the pipeline from flowing backwards.The bottom valve of water pump suction pipe also belongs to the safety check class.Safety check is divided by structure, can be divided into three kinds of Lift check valve, Swing check valve and butterfly check valves.Swing check valve is divided into three kinds of single-lobe formula, Double-disc type and multi-clove types.Pipeline has the slag stock pump system of higher flow-reversing impingement pressure during for frequent start-stop and termination of pumping, not only to the damaging impact force of mechanical seal, and probably because of rotor reversing impeller is unloaded down and is caused the accident.For top problem, some enterprises add upper check valve in pipe-line system, and when termination of pumping, the flow-reversing impingement pressure of pipeline just can not work the mischief to impeller and mechanical seal like this.Because the safety check that adds in pipe-line system is common safety check, flow-reversing impingement pressure still can bring harm to pipeline.
The model utility content
The technical problems to be solved in the utility model is that existing safety check can not effectively carry out pressure release to pipeline, and spool weares and teares easily, and providing a kind of can carry out pressure release and the nonabradable single-lobe Swing check valve of spool to pipeline for this reason.
The technical solution of the utility model is: a kind of single-lobe Swing check valve for slag stock pump system, and it comprises valve plate and spool, described valve plate is provided with 1-4 through hole.
Through hole in the such scheme on the valve plate is preferably 4.
Spool described in the such scheme is surrounded by rubbery outer cover outward.
The beneficial effects of the utility model are to alleviate loine pressure by the through hole that is provided with for pressure release at valve plate, and spool is surrounded by rubbery outer cover outward, have improved working life.
Description of drawings
Fig. 1 is the utility model schematic representation;
Fig. 2 is that the utility model uses schematic representation;
Among the figure, 1, spool, 2, valve plate, 3, through hole.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 2, the utility model comprises valve plate 2 and spool 1, and described valve plate is provided with 1-4 through hole 3.
The utility model passes through at several pressure release through holes of valve plate design, and preferably 4, also can there be 2 or 3, be evenly distributed on the circumferential surface of valve plate, can effectively reduce the pressure of pipeline.
The utility model can on the valve plate with the technological scheme of pressure release through hole at surrounded one deck rubbery outer cover of spool, avoid spool to be worn, improve the working life of valve.
Claims (2)
1. single-lobe Swing check valve that is used for slag stock pump system, it comprises valve plate (2) and spool (1), it is characterized in that described valve plate is provided with 4 through holes (3).
2. a kind of single-lobe Swing check valve for slag stock pump system as claimed in claim 1 is characterized in that the outer rubbery outer cover that is surrounded by of described spool (1).
