Novel injection pump

Abstract

The utility model provides a novel injection pump and belongs to the technical field of water pumps. The problems that an existing injection pump lacks a filtering structure, and use is affected are solved. The novel injection pump comprises a valve body with an air inlet and a steam inlet, a filter device is arranged at the air inlet, and the filter device is composed of a built-in mounting sleeve, a filter framework positioned at the top of the built-in mounting sleeve and a filter screen fixed in the filter framework. A plurality of groups of magnetic filtering assemblies consisting of a plurality of magnetic rings are arranged in the filtering device, a connecting hole is formed in each magnetic ring, a supporting sleeve is arranged in each connecting hole, the end part of each supporting sleeve extends outwards to form a positioning ring, and a threaded sleeve for limiting the positioning ring is in threaded connection with the interior of the air inlet. The filter has the advantages of being good in filtering effect and improving the using effect.

Description

Technical Field

[0001] The utility model belongs to the technical field of water pumps and relates to a jet pump, in particular to a novel jet pump. Background Art

[0002] The jet pump has two inlets, namely, an air inlet and a steam inlet. Currently, the air inlet of the jet pump lacks a filtering structure, which causes impurities in the air to enter the pump body, affecting its use. Summary of the invention

[0003] The purpose of the utility model is to provide a new type of jet pump with improved use effect in view of the above problems existing in the prior art.

[0004] The purpose of the utility model can be achieved through the following technical solutions: a new type of jet pump, including a valve body with an air inlet and a steam inlet, characterized in that a filter device is provided at the air inlet, and the filter device is composed of a built-in mounting sleeve, a filter frame positioned on the top of the built-in mounting sleeve and a filter screen fixed in the filter frame, the filter device is provided with a plurality of groups of magnetic filter components composed of a plurality of magnetic rings, each of the magnetic rings is provided with a connecting hole, and a support sleeve is provided in the connecting hole, and the end of the support sleeve extends outward to form a positioning ring, and the air inlet is internally threadedly connected with a screw sleeve for limiting the positioning ring.

[0005] In the above-mentioned novel jet pump, the top of the built-in mounting sleeve has an outwardly protruding positioning extension ring, and the filtering framework is Z-shaped and abuts against the positioning extension ring.

[0006] Compared with the prior art, the novel jet pump has the advantages of good filtering effect and improved use effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] Figure 1 It is a sectional view of the novel jet pump.

[0008] In the figure, 1. air inlet; 2. steam inlet; 3. valve body; 4. built-in mounting sleeve; 5. filter frame; 6. filter screen; 7. magnetic ring; 8. magnetic filter assembly; 9. support sleeve; 10. positioning ring; 11. screw sleeve; 12. positioning extension ring. DETAILED DESCRIPTION

[0009] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0010] like Figure 1As shown, the novel jet pump comprises a valve body 3 with an air inlet 1 and a steam inlet 2, a filter device is provided at the air inlet 1, and the filter device is composed of a built-in mounting sleeve 4, a filter skeleton 5 positioned at the top of the built-in mounting sleeve 4, and a filter screen 6 fixed in the filter skeleton 5, a plurality of groups of magnetic filter components 8 composed of a plurality of magnetic rings 7 are provided in the filter device, each magnetic ring 7 is provided with a connecting hole, and a support sleeve 9 is provided in the connecting hole, and the end of the support sleeve 9 extends outward to form a positioning ring 10, the air inlet 1 is internally threadedly connected with a screw sleeve 11 for limiting the positioning ring 10, and various impurities in the air are adsorbed and filtered by the magnetic filter component 8 and the filter screen 6.

[0011] Preferably, the top of the built-in installation sleeve 4 has an outwardly protruding positioning extension ring 12 , and the filter skeleton 5 is Z-shaped and rests on the positioning extension ring 12 .

[0012] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0013] Although the terms such as air inlet 1, steam inlet 2, valve body 3, built-in mounting sleeve 4, filter frame 5, filter screen 6, magnetic ring 7, magnetic filter assembly 8, support sleeve 9, positioning ring 10, screw sleeve 11, positioning extension ring 12 are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
