Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure pipelines of converter soft water pumps, in particular to a valve with an anti-scouring valve sleeve. Background Art

[0002] The converter soft water pump room is used to supply water to the converter boiler. The pipeline pressure is high pressure (working pressure is 45Kpa). The bypass valve of the high-pressure pipeline in the converter soft water pump room is a gate valve with a cast valve body. The valve is responsible for pressure relief. Due to the existing valve body structure and frequent scouring by high-pressure water (working pressure is 45Kpa), the inside of the gate valve outlet neck is often scoured and leaks. One valve is replaced every three months, which seriously shortens the service life of spare parts and increases spare parts consumption. The annual usage reaches dozens. At the same time, it is difficult to replace. It is necessary to stop the pump online and manually open and close multiple valves, which is time-consuming and labor-intensive and affects production. Utility Model Content

[0003] According to the technical problem raised above, a valve with an anti-scouring valve sleeve is provided. The technical means adopted by the utility model are as follows:

[0004] A valve with an anti-scour valve sleeve comprises a gate valve and a valve sleeve body, wherein the valve sleeve body is arranged inside a valve cavity at an outlet of the gate valve, the valve sleeve body is 3-3.5 mm away from the valve cavity outlet end of the gate valve, the outer diameter of the valve sleeve matches the inner diameter of the gate valve to be installed, the total length of the valve sleeve is 80-90 mm, the thickness of the valve sleeve is 5-8 mm, and the inner diameter of the valve sleeve is 47-50 mm.

[0005] Furthermore, the valve sleeve is made of white steel.

[0006] Furthermore, the outer diameter of the valve sleeve body matches the inner diameter of the gate valve outlet valve cavity, and there is a preset gap between the two.

[0007] The utility model has the following advantages:

[0008] The utility model is applied to the bypass valve of the high-pressure pipeline in the converter soft water pump room, which solves the problem of anti-scouring and water leakage of the internal cavity of the converter high-pressure water gate valve. According to the actual working conditions on site and production needs, the utility model is embedded in the valve outlet cavity before the valve is installed, so that high-pressure water impacts the utility model, protecting the valve inner neck cavity body from wear or delaying wear, extending the service life of spare parts, saving spare parts consumption, ensuring production, and the current operation effect is good.

[0014] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] like Figure 1 , Figure 2 As shown, an embodiment of the utility model discloses a valve with an anti-scour valve sleeve, including a gate valve and a valve sleeve body, wherein the valve sleeve body is arranged inside a valve cavity at an outlet of the gate valve, the valve sleeve body is 3-3.5 mm away from the valve cavity outlet end of the gate valve, the outer diameter of the valve sleeve matches the inner diameter of the gate valve to be installed, the total length of the valve sleeve is 80-90 mm, the thickness of the valve sleeve is 5-8 mm, and the inner diameter of the valve sleeve is 47-50 mm.

[0016] Furthermore, the valve sleeve is made of white steel.

[0017] Furthermore, the outer diameter of the valve sleeve body matches the inner diameter of the gate valve outlet valve cavity, and there is a preset gap between the two. The valve sleeve body is movably arranged in the gate valve outlet valve cavity, and can present a rotating state impacted by water flow, so that any part of the valve sleeve body can be impacted by high-pressure water, thereby enhancing the service life of the device.

[0018] like Figure 3As shown, further, it also includes an inner sleeve retaining ring, the inner sleeve retaining ring includes a retaining ring part and a mounting part, the retaining ring part has the same inner diameter and outer diameter as the inner sleeve retaining ring, and the mounting part can be clamped at the gate valve outlet.

[0019] Furthermore, the inner sleeve retaining ring and the inner sleeve retaining ring and the gate valve outlet are all provided with sealing rubber rings.

[0020] Specifically, the specification of the rubber ring between the inner sleeve retaining ring and the inner sleeve retaining ring is 47-50mm, and the specification of the rubber ring between the inner sleeve retaining ring and the gate valve outlet is 49-52mm.

[0021] The gate valve used in the valve of the present application can be a conventional gate valve in the prior art. In actual application, the valve is installed on the pipeline through the valve flange 7, and water enters the valve cavity on the inlet side of the pipeline valve. Since the valve is a manual regulating valve, the valve screw is arranged on the valve screw bracket 2. The valve screw 5 is adjusted by the valve handwheel 1 so that it is in a non-fully open state. When water flows through the valve cavity, the valve gate plate 4 hinders the water flow, and the water flow changes in the valve cavity, which directly causes the valve cavity 3 to be scoured (the valve cavity is a casting). A converter scour-resistant high-pressure water gate valve solves the scouring of the gate valve cavity by high-pressure water, protects the valve inner neck cavity body from wear or delays wear, extends the service life of spare parts, saves spare parts consumption, ensures production, and has a good operating effect.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
