Abstract
Description
Technical Field
[0001] The utility model relates to the field of industrial water systems, in particular to a leak repairing device, in particular to a leak repairing device for a cast iron housing of a water system pump or valve. Background Art
[0002] The main industrial water system of a factory generally supplies multiple branches or operating areas at the same time. The main water system of a branch or operating area also supplies multiple sets of equipment at the same time, and supplies continuously for a long time 24 hours a day to ensure the continuity and high efficiency of production. It will only be completely shut down for maintenance at a specific time. The shells of pumps and various valves in the main water system are generally cast iron shells. The shells themselves are prone to defects such as local shrinkage holes. The inner wall is corroded by water after long-term water flow, and the defective parts continue to become thinner, the pressure-bearing capacity decreases, and finally rusts through and leaks.
[0003] In view of the above working mode, it is impossible to directly weld and repair the cast iron shell or replace the pump / valve. The prior art usually adopts unconventional methods to plug the leak, such as driving wooden wedges into the leaking place or wrapping it with rubber, etc. This method will cause problems such as incomplete water sealing or unsustainable water sealing state, thereby causing energy waste. Utility Model Content
[0004] In view of the above problems, the utility model proposes a leak-proof device, which uses an internal threaded sleeve and a threaded fastener to use leak-proof materials to repair the cast iron housing of a water system pump or valve, greatly reducing welding requirements and achieving a long-lasting leak-proof effect.
[0005] The utility model can be implemented or realized by the following schemes:
[0006] A leak-sealing device comprises an internally threaded sleeve, a leak-sealing material, a pressing sheet and a threaded fastener, wherein the internally threaded sleeve is fixed on a shell body and surrounds a leaking port of the shell body; the leak-sealing material and the pressing sheet are placed in the internally threaded sleeve, the leak-sealing material blocks the leaking port, and the pressing sheet squeezes the leak-sealing material; the threaded fastener is screwed into the internally threaded sleeve and presses the pressing sheet and the leak-sealing material.
[0007] Furthermore, the housing is a housing of an industrial water system pump or valve.
[0008] Furthermore, the shell is made of cast iron.
[0009] Furthermore, the internally threaded sleeve and the shell are fixed by welding.
[0010] Furthermore, the welding method is full welding or partial welding.
[0011] Furthermore, the diameter of the pressing sheet is 3 times the maximum length of the water leakage port and is slightly smaller than the diameter of the internal threaded sleeve.
[0012] Furthermore, the internally threaded sleeve is a nut.
[0013] Furthermore, the threaded fastener is a bolt, a screw, a threaded rod or a stud.
[0014] Furthermore, the pressing sheet is a steel plate.
[0015] Furthermore, the leak-proof material is silica gel.
[0016] Compared with the prior art, the utility model has the following beneficial effects:
[0017] Rapid, efficient and pressure-sealed repair of leaks in cast iron housings of pumps and valves in industrial water systems can effectively solve the problem of not being able to repair leaks due to production continuity issues, thereby avoiding energy waste and reducing losses caused by long-term leaks. The water sealing state is maintained for a long time, sufficient to ensure normal use after sealing. In addition, the internal threaded casing and the housing are not fully welded, which greatly reduces the welding requirements.
[0018] The utility model is put into use with excellent effect, and pumps and valves are widely used in industrial water systems, so the application prospect of the utility model is very broad. BRIEF DESCRIPTION OF THE DRAWINGS
[0019] Figure 1 It is a structural schematic diagram of the utility model.
[0020] Figure numerals: 1, internal threaded casing; 2, leak-proof material; 3, pressing sheet; 4, threaded fastener; 5, solder; A, shell; B, water leak; C, water. DETAILED DESCRIPTION
[0021] The utility model is further described below in conjunction with the accompanying drawings:
[0022] like Figure 1 As shown, a leak repairing device comprises an internal threaded casing 1, a leak repairing material 2, a pressing sheet 3 and a threaded fastener 4.
[0023] The internal threaded sleeve 1 is fixed on the housing A to be repaired, surrounding the leaking port B on the housing A, and is fixed by welding. The housing A mainly refers to the housing corresponding to the pump or valve of the industrial water system, which is generally made of cast iron. It should be noted that full welding is not required during welding, because the weld does not need to be sealed with water, and is only used to fix the leak-proof material and the pressing sheet, so the welding requirements are reduced, and the difficulties caused by the poor weldability of cast iron are avoided.
[0024] The shape of the pressing sheet 3 matches the internal threaded casing 1, is circular, has a thickness of 2 mm, and a diameter that is 3 times the maximum length of the leaking port B and is slightly smaller than the diameter of the internal threaded casing 1, so that the leaking port B can be blocked and the pressing sheet 3 can be placed in the internal threaded casing 1. The sealing material 2 and the pressing sheet 3 are placed in the internal threaded casing 1, and the sealing material 2 blocks the leaking port B.
[0025] The threaded fastener 4 is screwed into the internal threaded sleeve 1 to squeeze the pressing sheet 3, so that the leak-proof material 2 fits tightly against the leaking port B to achieve a plugging effect.
[0026] The internal threaded sleeve 1, the leak-proof material 2, the pressing sheet 3, and the threaded fastener 4 all need to be flexibly selected according to the size of the leaking port B.
[0027] Preferably, the internal threaded sleeve 1 is a nut, the leak-proof material 2 is silicone, the pressing sheet 3 is a steel plate, and the threaded fastener 4 is a bolt. When in use, the nut is first welded to the shell A through the solder 5, and then the silicone is applied to the steel plate with a thickness of about 3 mm. When the silicone hardens to 80%, the silicone and the steel plate are placed in the nut, and then the bolt is screwed into the nut to squeeze the steel plate, thereby squeezing the silicone until the leaking port B no longer leaks water C.
[0028] It should be noted that, for the above-mentioned implementation mode, if the nut is replaced by other internal threaded sleeves, the bolt is replaced by screws, screws, studs, etc., and the steel plate is replaced by other pressed sheets, as long as they can cooperate to achieve the technical effect, there is no specific restriction on the material selection.
