[0002] Heating is a technology that uses artificial methods to supply heat to the room to maintain a certain temperature in the room in order to create suitable living or working conditions. The heating system consists of three main parts: heat source (heat medium preparation), heat circulation system (pipeline network or heat medium transportation) and heat dissipation equipment (heat medium utilization).

[0003] Valves are an important part of the heating system. They are used to control the flow of heat medium and cut off the heat medium. The heavy valves in the heat medium preparation and outdoor hot coal transportation system are operated by professionals. After entering the building, the property or individuals will operate them. Traditional valves are mostly screw-type. Non-professionals cannot tell the positive and negative directions when turning the handwheel, and cannot open or close the valve in time. Therefore, a valve device for heating is proposed. The connecting rod is held to move the valve core downward and insert it into the valve body to cut off the heat medium inside. The connecting rod is moved upward to drive the valve core upward, so that the heat medium can flow in the valve body. Utility Model Content

[0004] In response to the problems in the existing technology, the utility model provides a valve device for heating. The valve core is moved downward by holding the connecting rod to be inserted into the valve body to cut off the heat medium inside. The connecting rod is moved upward to drive the valve core upward, so that the heat medium can flow in the valve body.

[0005] The technical solution adopted by the utility model to solve the technical problem is a valve device for heating, wherein a circular layer plate is fixed inside the valve body by bolts, a filter screen is fixed to the inner end of the valve body located at the top of the circular layer plate by bolts, a protective tube is welded to the top of the valve body, a fixing assembly is provided inside the protective tube, a connecting rod is sleeved through the inside of the protective tube, the connecting rod is located at the bottom of the valve body and is fixed to a valve core by bolts, and a rubber sleeve is sleeved on the outer side of the valve core;

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] Hold the connecting rod and move the valve core downward to insert it into the valve body to cut off the heat medium inside. Move the connecting rod upward to drive the valve core upward so that the heat medium can flow in the valve body. Figure 1-6 As shown, a heating valve device according to the present invention comprises a circular layer plate 4 fixed to the inside of the valve body 1 by bolts, a filter screen 5 fixed to the inner end of the valve body 1 located at the top of the circular layer plate 4 by bolts, a protective tube 2 welded to the top of the valve body 1, a fixing assembly 7 is provided inside the protective tube 2, a connecting rod 3 is sleeved through the inside of the protective tube 2, and a valve core 9 is fixed to the connecting rod 3 at the bottom of the valve body 1 by bolts, and a rubber sleeve 6 is sleeved on the outside of the valve core 9;

[0027] The fixing assembly 7 includes a limiting groove 701 opened on one side of the protective tube 2, and a compression spring 703 is fixed inside the limiting groove 701 by bolts. A round head clamping column 702 is sleeved on one end of the limiting groove 701, and the end of the round head clamping column 702 located inside the limiting groove 701 is fixed to a limiting block 704 by bolts.

[0028] When in use, the valve core 9 is moved up and down by the connecting rod 3 to open or close the valve. The filter screen 5 can filter the heat medium flowing in the valve body 1. The compression spring 703 pushes the round head clamping column 702 to extend, which can assist in fixing the connecting rod 3 after moving up and down.

[0029] For example, Figure 4As shown, the utility model also includes that a rectangular limit groove 11 is opened at the bottom of the valve core 9, a rectangular limit column 10 is welded on the top of the circular layer plate 4, the top of the rectangular limit column 10 is located inside the rectangular limit groove 11, and a reserved groove 12 is opened equidistantly through the top of the circular layer plate 4 outside the rectangular limit column 10.

[0030] During use, when the valve core 9 is pushed up and down, the rectangular limit column 10 slides in the rectangular limit groove 11, which can prevent the valve core 9 from rotating without affecting its up and down movement. The opening of the reserved groove 12 prevents the circular layer plate 4 from affecting impurities and the like from falling onto the blocking cover 8.

[0031] For example, Figure 6 As shown, the utility model further includes that the bottom of the valve body 1 is connected to a plug cover 8 through a threaded groove, and the top of the plug cover 8 is sleeved with a sealing ring 15.

[0032] When in use, the plugging cover 8 can be opened to remove impurities filtered out of the valve body 1 , and the sealing ring 15 seals between the plugging cover 8 and the valve body 1 .

[0033] For example, Figure 4 As shown, the present invention further includes that a second locking hole 13 is formed at one end of the connecting rod 3 , and a first locking hole 14 is formed at one end of the connecting rod 3 located at the bottom of the second locking hole 13 .

[0034] During use, the second clamping hole 13 and the first clamping hole 14 are provided to facilitate the insertion of one end of the round-head clamping column 702 to fix the connecting rod 3 after it moves up and down.

[0035] For example, Figure 1 As shown, the present invention further includes: a feed pipe 16 is welded to one side of the valve body 1 , and a discharge pipe 17 is welded to the side of the valve body 1 away from the feed pipe 16 .

[0036] When in use, the heat medium flows into the valve body 1 through the feed pipe 16 and flows out through the discharge pipe 17 .

[0037] For example, Figure 4 As shown, the present invention also includes that the circular layer plate 4, the valve core 9 and the rectangular limiting column 10 are all made of stainless steel.

[0038] When in use, the circular layer plate 4, the valve core 9 and the rectangular limit column 10 made of stainless steel have high strength and are not prone to corrosion and deformation.

[0039] When the utility model is in use, the heat medium flows into the valve body 1 through the feed pipe 16 and flows out through the discharge pipe 17. When the heat medium flows in the valve body 1, the filter 5 can filter the impurities inside the valve body 1. The filtered impurities fall onto the blocking cover 8 through the reserved groove 12. The blocking cover 8 can be opened to remove the filtered impurities in the valve body 1.

[0040] A person holds the connecting rod 3 and moves the valve core 9 downward, so that the valve core 9 moves to the circular layer plate 4, which can block the feed pipe 16 and the discharge pipe 17, thereby cutting off the heat medium flowing in the valve body 1. A person holds the connecting rod 3 and moves the valve core 9 upward, so that the heat medium can flow in the valve body 1.

[0041] A rubber sleeve 6 is provided on the outside of the valve core 9 to improve the sealing between the valve core 9 and the valve body 1. When the valve core 9 moves up and down, the top of the rectangular limit column 10 slides in the rectangular limit groove 11, which can limit the valve core 9 without affecting its up and down movement, thereby preventing the valve core 9 and the connecting rod 3 on its top from rotating.

[0042] When the connecting rod 3 moves downward and the valve core 9 moves to the circular layer plate 4, the compression spring 703 in the limiting groove 701 pushes the round head clamping column 702 to extend, so that one end of the round head clamping column 702 is inserted into the second clamping hole 13, thereby fixing the connecting rod 3 after moving downward. When the connecting rod 3 moves upward and the valve core 9 moves to the top of the valve body 1, the compression spring 703 in the limiting groove 701 pushes the round head clamping column 702 to extend, so that one end of the round head clamping column 702 is inserted into the first clamping hole 14, thereby fixing the connecting rod 3 after moving upward.
