Abstract
The utility model relates to an improvement on a structure of a small-bore seal-free check valve of a self-control self-priming pump, which comprises an upper flange, a lower flange, a rib plate, a guide rod and a guide plate. The improvement on the structure is characterized by further comprising a first pipeline connected to the upper flange in penetrating mode, a third pipeline connected to the lower flange in penetrating mode and a second pipeline connected between the first pipeline and the third pipeline in penetrating mode. Pipe diameter of the second pipeline is large than that of the first pipeline and that of the third pipeline. The guide rod is disposed inside the second pipeline, both sides of the guide rod are respectively connected to the rib plate, the other end of the rib plate is fixedly connected to the inner lateral wall of the second pipeline, and the lower portion of the guide rod is connected to the guide plate which is slightly higher than an upper pipe orifice of the third pipeline. The improvement on the structure has the advantages of being simple in structure, enabling structural design of the check valve to be more reasonable, thoroughly resolving the problem that delivery lift difference after the check valve is too big, and producing no harmful effect on performance of the pump. In addition, parts and components used by the check valve are standardized to the greatest extent, trouble of re-processing is reduced, and processing working hours and cost are saved.
Description
Technical field
The utility model relates to safety check, particularly a kind of improvement of small-bore nothing sealing automatic control self-priming pump check valve structure.
Background technique
At present, conventional Vertical Lift Check Valves is only considered problems such as space and installation, does not consider the influence of safety check area of passage to the pump discharge lift, smaller than existing design of the area of passage of safety check local location.Be welded with a steel pipe 2 and flange 1 like the valve body among Fig. 1; The area of passage of valve is after removing guide rod 4 and gusset 3 occupation space; Be far smaller than the desired area of passage of regulation flow, thus can be very little at the delivery side of pump flow, and lift also will be far short of what is expected with the lift of actual demand.
The model utility content
The utility model purpose is in order to solve small-bore nothing sealing automatic control self-priming pump the too big problem of lift gap behind the safety check to be installed, and a kind of improvement of novel small-bore nothing sealing automatic control self-priming pump check valve structure is provided.
The utility model is achieved in that the improvement of small-bore nothing sealing automatic control self-priming pump check valve structure; Comprise: upper and lower flange, gusset, guide rod and guide plate; It is characterized in that: also comprise with upper flange connect first pipeline is connected, with the 3rd pipeline, first pipeline and the 3rd pipeline that the lower flange perforation is connected between second pipeline that is tightly connected; The caliber of second pipeline is greater than first pipeline and the 3rd pipeline; Be provided with said guide rod at second pipe interior, the both sides of guide rod are connected with a gusset respectively, and the other end of this gusset is fixedly connected with the madial wall of second pipeline; The bottom of this guide rod is connected with said guide plate, and this guide plate is a little more than the upper orifice of the 3rd pipeline.
First pipeline is identical with the caliber of the 3rd pipeline.
The centerline of first pipeline, second pipeline, the 3rd pipeline, guide rod and guide plate is on a straight line.
The pipe range of second pipeline is greater than first pipeline and the 3rd pipeline.
First pipeline, second pipeline, the 3rd pipeline are straight tube, are tightly connected by steel plate between the upper orifice of the lower nozzle of first pipeline and second pipeline, are tightly connected by steel plate between the upper orifice of the lower nozzle of second pipeline and the 3rd pipeline.
The utility model advantage is: simple in structure, and make the structural design of safety check more reasonable, thoroughly solve the too big problem of lift gap behind the safety check; Pump performance is had no adverse effects; And the standardization of trying one's best of the used component of safety check has reduced the trouble of reprocessing, practices thrift machining period and cost.
Description of drawings
Fig. 1 is the prior art constructions schematic representation.
Fig. 2 is the structural representation of the utility model.
Embodiment
Among Fig. 2; The improvement of small-bore nothing sealing automatic control self-priming pump check valve structure; Comprise: upper and lower flange 1, gusset 3, guide rod 4 and guide plate 5 are divided into three parts with valve body: second pipeline 22 that is tightly connected between the 3rd pipeline 23, first pipeline and the 3rd pipeline that connect first pipeline 21 that is connected with upper flange, is connected with the lower flange perforation.The caliber of second pipeline is stipulated the desired area of passage of flow to satisfy, and is provided with said guide rod at the second maximum pipe interior of volume greater than first pipeline and the 3rd pipeline; The both sides of guide rod are connected with a gusset respectively; The other end of this gusset is fixedly connected with the madial wall of second pipeline, and the bottom of this guide rod is connected with said guide plate, and this guide plate is a little more than the upper orifice of the 3rd pipeline; Make the structural design of safety check more reasonable, thoroughly solve the too big problem of lift gap behind the safety check.
First pipeline is identical with the caliber of the 3rd pipeline, and the area of passage when medium gets into valve body and flows out valve body is constant basically like this, and the flow lift of pump is all had no adverse effects.
The centerline of first pipeline, second pipeline, the 3rd pipeline, guide rod and guide plate is on a straight line.
The pipe range of second pipeline makes the operating space well-to-do greater than first pipeline and the 3rd pipeline.
First pipeline, second pipeline, the 3rd pipeline are straight tube, and the standardization of trying one's best of the used component of safety check has reduced the trouble of reprocessing, practices thrift machining period and cost.Be tightly connected by steel plate 6 between the upper orifice of the lower nozzle of first pipeline and second pipeline, be tightly connected by steel plate between the upper orifice of the lower nozzle of second pipeline and the 3rd pipeline.Between the pipeline or other Placement all adopt the mode of welding.
Below only expressed the mode of execution of the utility model, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model patent scope.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.Therefore, the protection domain of the utility model patent should be as the criterion with accompanying claims.
The utility model advantage is: simple in structure, and make the structural design of safety check more reasonable, thoroughly solve the too big problem of lift gap behind the safety check; Pump performance is had no adverse effects; And the standardization of trying one's best of the used component of safety check has reduced the trouble of reprocessing, practices thrift machining period and cost.
