Description
Technical Field
The utility model belongs to mechanical structure design field involves a valve is proclaimed oneself in centrifugal pump exhaust.
Background
The alternating-current oil transfer pump is of a structure with a detachable pump core and a detachable pump shell, and a product is installed at the bottom of the oil tank. When the pump core is installed, gas exists in front of the pump core and the pump shell, and the gas cannot be normally discharged. When the pump is in operation and there is no way for gas to escape, this phenomenon is known as "gas-lock" of the pump. This state may cause: the pump has no liquid discharge and obvious vibration.
SUMMERY OF THE UTILITY MODEL
The utility model aims at: the air-exhausting self-sealing valve of the centrifugal pump is provided to eliminate the air-bound phenomenon of the pump.
The technical scheme of the utility model is that:
the first aspect provides a valve is proclaimed oneself in centrifugal pump exhaust, the valve is proclaimed oneself in centrifugal pump exhaust is installed on the centrifugal pump body 4, and the valve is proclaimed oneself in centrifugal pump exhaust includes valve seat 1, valve lid 2, sealing washer 3, wherein, valve seat 1 is installed in the 4 exits of centrifugal pump body, valve seat 1 is through external screw thread and 4 interior screw-thread fit pretensions of centrifugal pump body, valve lid 2 is installed in the mounting hole of valve seat 1, valve lid 2 is fluoroether rubber, valve lid 2 is for including canopy and umbrella stick, wherein the umbrella lid is located the sealed face upper end of valve seat 1, the umbrella stick passes sealed face, be provided with the boss on the umbrella stick.
Further, still include sealing washer 3, sealing washer 3 cramps in the valve seat 1 seal groove, installs in the clearance between valve seat 1 and the centrifugal pump body 4 through valve seat 1.
Furthermore, the umbrella cap of the valve cover 2 is provided with a reinforcing rib.
Further, the valve seat 1 is provided with an exhaust hole.
Further, the exhaust hole is a plurality of and evenly distributed around the mounting hole.
Furthermore, the umbrella frame of the valve cover 2 is provided with a sealing ball.
So the utility model has the technical effects that:
the exhaust self-sealing valve structure improves the safety of the centrifugal pump, can ensure the normal work of the centrifugal pump, has simple valve processing and mounting structure, and is convenient to maintain and replace.
Drawings
Figure 1 the utility model discloses a valve structure installation cross-section is proclaimed oneself.
Figure 2 the utility model discloses a from valve structure cross-sectional view.
Wherein, valve seat 1, valve lid 2, sealing washer 3, the centrifugal pump body 4.
Detailed Description
In order to reduce the occurrence of the phenomenon of air binding of the product and prevent the product from being damaged, an exhaust type self-sealing valve is designed at the outlet part of the pump, so that the normal working operation of the product is ensured.
As shown in fig. 1 and 2, the utility model discloses a first aspect provides a valve is proclaimed oneself in centrifugal pump exhaust, the valve is proclaimed oneself in the centrifugal pump exhaust and is installed on the centrifugal pump body 4 to the valve is proclaimed oneself in the centrifugal pump exhaust and includes valve seat 1, valve cover 2, sealing washer 3, wherein, valve seat 1 is installed in the 4 exits of centrifugal pump body, valve seat 1 passes through the external screw thread and the 4 interior screw-thread fit pretensions of the centrifugal pump body, valve cover 2 is installed in valve seat 1's mounting hole, valve cover 2 is fluoroether rubber, valve cover 2 is for including canopy and umbrella stick, wherein the canopy is located valve seat 1 sealing face upper end, the umbrella stick passes sealed face, be provided with the boss on the umbrella stick.
Further, still include sealing washer 3, sealing washer 3 cramps in the valve seat 1 seal groove, installs in the clearance between valve seat 1 and the centrifugal pump body 4 through valve seat 1.
Furthermore, the umbrella cap of the valve cover 2 is provided with a reinforcing rib.
Further, the valve seat 1 is provided with an exhaust hole.
Further, the exhaust hole is a plurality of and evenly distributed around the mounting hole.
Furthermore, the umbrella frame of the valve cover 2 is provided with a sealing ball.
The working principle is as follows:
1 when the pump shell is filled with gas which is not discharged, the gas can be discharged through a discharge valve, and the 'gas binding' is prevented. 2 after the gas is discharged, the rubber convex circle returns to the original shape due to extrusion deformation, so that the umbrella cap returns to the original position, and the reverse sealing performance of the shell is ensured. 3 reinforcing ribs are added on the outer edge of the umbrella cap, so that the reverse sealing effect of the umbrella cap is improved, and the rubber part can be prevented from deforming due to long-time placement.
The utility model has the advantages that:
the exhaust self-sealing valve of the centrifugal pump is different from a valve structure in a traditional pipe joint form, the air-bound phenomenon that liquid cannot be conveyed even if the centrifugal pump is started due to the fact that low pressure formed in the central area of the impeller is not enough to suck liquid in the storage tank into the pump can be better solved, and the exhaust self-sealing valve of the centrifugal pump has the advantages of being small in size, simple in structure, convenient to machine and strong in sealing performance.
