Technical Field
[0001] The utility model belongs to the technical field of valves, and in particular relates to a thermal pipeline valve which is easy to clean. Background Art
[0002] Thermal pipelines, also known as thermal pipe networks, belong to a type of pressure pipelines. Their main function is to transport the heat energy produced by boilers to indoor heating equipment through heat media such as steam and hot water to meet the needs of production and life. Thermal pipelines start from boiler rooms, direct-fired machine rooms, heating centers, etc., forming multiple heating pipeline networks from heat sources to the thermal entrances of buildings. When hot water is used as the heating medium, the medium is prone to contain impurities such as scale. Therefore, for thermal pipeline valves, if they are not cleaned regularly, valve blockage is likely to occur. However, in the prior art, the cleaning of valves requires the valves to be disassembled, which is very inconvenient. Utility Model Content
[0003] In view of the above problems, the purpose of the utility model is to provide a thermal pipeline valve that is easy to clean. While the device has the function of intercepting impurities in the medium, it greatly facilitates the cleaning of the valve and solves the problem of unchanged cleaning when the valve is blocked.
[0004] To achieve the above objectives, the utility model provides the following technical solutions: a thermal pipe valve that is easy to clean, comprising a valve body, wherein a valve ball is provided inside the valve body, a limiting ring is provided on the inner side of the flow hole of the valve ball, a filter screen frame is inserted and installed on the inner side of the flow hole of the valve ball, a filter screen is penetrated and provided on the side surface of the filter screen frame, and an integrally formed hook-out matching seat is provided on the inner side of the filter screen frame, a sewage pipe is provided on the side surface of the valve body, a sealing cover is provided at one end of the sewage pipe, an insertion seat is provided on the back of the sealing cover, a hook-out rod is inserted and installed on the inner side of the insertion seat, one end of the hook-out rod is connected to a rotating handle, the other end of the hook-out rod is connected to a hook plate, an anti-slip plate is provided on the outer side of the hook-out rod, a spring is provided on the inner side of the insertion seat, the spring is sleeved on the outer side of the hook-out rod, and one end of the sewage pipe is connected to a flange plate.
[0005] The beneficial effects of the utility model are as follows: when the valve needs to be opened, the valve ball is rotated by the hand wheel until the flow hole is connected to the valve channel, so that the medium can pass and the flow rate can be adjusted. It should be noted that when the valve ball of the device is opened, the valve ball is rotated until the limit ring is away from the medium entry direction to prevent the filter frame from being rushed into the valve channel at the medium output end, and the impurities in the medium can be blocked on the inner side of the filter frame through the filter. When the impurities inside the filter frame are to be cleaned, it is only necessary to rotate the valve ball until the flow hole is aligned with the sewage pipe, and then the turning handle can be pressed again to push the hook rod together with the hook plate to move to the side of the hook matching seat of the filter frame, and the turning handle can be turned to rotate the hook plate Until it is inserted into the hook-out matching seat, the handle can be released afterwards, and the rebound of the spring can assist in pulling the filter frame out from the inside of the valve ball. After unscrewing the bolts, the sealing cover can be pulled to remove it from the flange plate, and the filter frame can be taken out, the impurities on the inside of the filter frame can be dumped, and the filter frame can be cleaned. After cleaning the filter frame, the filter frame can be put back into the valve ball and the sealing cover can be reinstalled, which facilitates the cleaning of the valve. In summary, while the device has the function of intercepting impurities in the medium, it greatly facilitates the cleaning of the valve and solves the problem of unchanged cleaning when the valve is blocked.

[0010] As a further improvement of the above technical solution: the top of the valve ball is connected to the valve stem, and a hand wheel is installed on the top of the valve stem.
[0011] The beneficial effect of this improvement is that the valve ball can be driven to rotate by rotating the valve stem through the hand wheel.
[0012] To assist in positioning:
[0013] As a further improvement of the above technical solution: a positioning plug plate is provided on the back of the sealing cover, and a positioning plug hole is provided on the front of the flange plate.
[0014] The beneficial effect of this improvement is that when installing the sealing cover, the sealing cover is pushed toward the flange plate so that the positioning plug hole on the flange plate is inserted into the positioning plug plate on the sealing cover, thereby playing an auxiliary positioning role.
[0015] To help hook the rod outward:
[0016] As a further improvement of the above technical solution: the spring is a compression spring, one end of the spring is in contact with the anti-drop plate, and the other end of the spring is fixed to the inside of the insertion seat.
[0017] The beneficial effect of this improvement is that the spring used is a compression spring. When the rotating handle and the hook-out rod are pushed inward, the spring is compressed and stores force. When the rotating handle is released, the spring rebounds to help the hook-out rod move outward.
[0018] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the present invention.
[0026] like Figure 1-5As shown, a thermal pipeline valve that is easy to clean comprises a valve body 1, wherein a valve ball 2 is arranged inside the valve body 1, a limiting ring 5 is arranged inside the flow hole of the valve ball 2, a filter screen frame 6 is inserted and installed inside the flow hole of the valve ball 2, a filter screen frame 6 is penetrated and provided with a filter screen 7 on the side of the filter screen frame 6, an integrally formed hook-out matching seat 8 is arranged on the inner side of the filter screen frame 6, a sewage pipe 9 is arranged on the side of the valve body 1, a sealing cover 10 is arranged at one end of the sewage pipe 9, an insertion seat 11 is arranged on the back side of the sealing cover 10, a hook-out rod 12 is inserted and installed on the inner side of the insertion seat 11, a rotating handle 13 is connected to one end of the hook-out rod 12, and the other end of the hook-out rod 12 is connected to a hook plate 14, an anti-slip plate 15 is arranged on the outer side of the hook-out rod 12, a spring 16 is arranged on the inner side of the insertion seat 11, and the spring 16 is sleeved on the outer side of the hook-out rod 12, and a flange plate 18 is connected to one end of the sewage pipe 9.
[0027] When it is necessary to open the valve, the valve ball 2 is rotated by the hand wheel 4 until the flow hole is connected to the valve channel to allow the medium to pass and adjust the flow rate. It should be noted that when the valve ball 2 of the device is opened, the valve ball 2 is rotated until the limit ring 5 is away from the medium entry direction to prevent the filter frame 6 from being rushed into the valve channel at the medium output end. Impurities in the medium can be blocked on the inner side of the filter frame 6 through the filter screen 7. When it is necessary to clean the impurities inside the filter frame 6, it is only necessary to rotate the valve ball 2 until the flow hole is aligned with the drain pipe 9, and then the turning handle 13 can be pressed again to push the hook rod 12 together with the hook plate 14 to move to the side of the hook-out matching seat 8 of the filter frame 6, and the turning handle 13 can be rotated to make the hook plate 14 rotate to align with the hook-out matching seat 8 of the filter frame 6. The seat 8 is inserted, and then the handle 13 can be loosened. The rebound of the spring 16 can assist in pulling the filter frame 6 out from the inner side of the valve ball 2. After unscrewing the bolt 20, the sealing cover 10 can be pulled to remove it from the flange plate 18, and the filter frame 6 can be taken out, and the impurities inside the filter frame 6 can be dumped and the filter frame 6 can be cleaned. After the filter frame 6 is cleaned, the filter frame 6 can be put back into the valve ball 2, and the sealing cover 10 can be reinstalled, which facilitates the cleaning of the valve. In summary, while the device has the function of intercepting impurities in the medium, it greatly facilitates the cleaning of the valve and solves the problem of unchanged cleaning when the valve is blocked.
[0028] The flange plate 18 and the sealing cover 10 are connected via bolts 20 .
[0029] The flange plate 18 and the sealing cover 10 are connected and fixed by bolts 20 .
[0030] The top of the valve ball 2 is connected to the valve stem 3 , and a hand wheel 4 is installed on the top of the valve stem 3 .
[0031] The valve ball 2 can be driven to rotate by rotating the valve stem 3 through the hand wheel 4.
[0032] A positioning plug plate 17 is disposed on the back of the sealing cover 10 , and a positioning plug hole 19 is disposed on the front of the flange plate 18 .
[0033] When installing the sealing cover 10, the sealing cover 10 is pushed toward the flange plate 18 so that the positioning holes 19 on the flange plate 18 are inserted into the positioning plug plates 17 on the sealing cover 10, thereby playing a role in auxiliary positioning.
[0034] The spring 16 is a compression spring, one end of the spring 16 is in contact with the anti-drop plate 15 , and the other end of the spring 16 is fixed to the inside of the insertion seat 11 .
[0035] The spring 16 is a compression spring. When the handle 13 and the hooking rod 12 are pushed inward, the spring 16 is compressed and stores force. When the handle 13 is released, the spring 16 rebounds to help the hooking rod 12 move outward.
[0036] Working principle and use process of the utility model: When the device is used, the valve stem 3 is rotated by the hand wheel 4 to drive the valve ball 2 to rotate until the flow hole of the valve ball 2 is aligned with the sewage pipe 9, and the fixing between the flange plate 18 and the sealing cover 10 by the bolts 20 is released. After the sealing cover 10 is removed, the filter frame 6 is inserted into the sewage pipe 9, and then the hook plate 14 at one end of the hook rod 12 on the sealing cover 10 is inserted into the hook matching seat 8 on the sewage pipe 9, and the sealing cover 10 can be pushed toward the direction of the flange plate 18, so that the positioning socket 19 on the flange plate 18 and the positioning plug plate 17 on the sealing cover 10 are inserted, and the flange is re-aligned with the bolts 20. After fixing the plate 18 and the sealing cover 10, the handle 13 can be continuously pushed to drive the hook rod 12 to press inward, thereby pushing the filter frame 6 to be completely inserted into the flow hole of the valve ball 2, so that one end of the filter frame 6 is against the limit ring 5 on the inner side of the valve ball 2, and then the handle 13 is rotated to disengage the hook plate 14 from the insertion connection with the hook matching seat 8, and the handle 13 is released. Under the action of the rebound force of the spring 16, the hook plate 14 is driven to completely enter the inner side of the sewage pipe 9 without affecting the rotation of the valve ball 2. At this time, the valve is in a closed state. When the valve needs to be opened, the valve ball 2 is rotated by the hand wheel 4 until the flow hole is connected with the valve channel. The medium passes through and adjusts the flow rate. It should be noted that when the valve ball 2 of the device is opened, the valve ball 2 rotates to the limit ring 5 away from the medium entry direction to prevent the filter frame 6 from being rushed into the valve channel at the medium output end. The impurities in the medium can pass through the filter screen 7 and be blocked on the inner side of the filter frame 6. When you want to clean the impurities inside the filter frame 6, you only need to rotate the valve ball 2 until the flow hole is aligned with the drain pipe 9, and then press the handle 13 again to push the hook rod 12 together with the hook plate 14 to move to the side of the hook-out matching seat 8 of the filter frame 6, rotate the handle 13 to rotate the hook plate 14 to insert into the hook-out matching seat 8, and then release the handle 13 The rebound of the spring 16 can assist in pulling the filter screen frame 6 out from the inner side of the valve ball 2. By unscrewing the bolt 20, the sealing cover 10 can be pulled to remove it from the flange plate 18, and the filter screen frame 6 can be taken out, and the impurities inside the filter screen frame 6 can be dumped and the filter screen frame 6 can be cleaned. After the filter screen frame 6 is cleaned, the filter screen frame 6 can be put back into the valve ball 2 and the sealing cover 10 can be reinstalled, which facilitates the cleaning of the valve. In summary, while the device has the function of intercepting impurities in the medium, it greatly facilitates the cleaning of the valve and solves the problem of unchanged cleaning when the valve is blocked.
