Description

Technical Field

[0001] The utility model relates to a pressure control valve, in particular to a suspended pipeline pressure control valve. Background Art

[0002] Solar water heating systems are widely used. They can collect solar heat and transfer the heat to water storage tanks through control systems and pipe insulation systems to provide hot water for production and life. However, solar water heating systems involve a large number of pipes, and each pipe needs to be equipped with a related ball valve for control, which makes the entire installation extremely complicated. Each pipe is also randomly distributed, resulting in each other's installation space being occupied, making it extremely difficult to complete the installation of all pipes.

[0003] In order to solve the above problems, a pipeline pressure control valve is generally used to connect multiple pipelines at the same time, and different pipelines are controlled by multiple ball valves on the pipeline pressure control valve. Although this integrated connection method can make the pipeline layout orderly, the pipeline pressure control valve needs to fix its own position to ensure its stability when connected to multiple pipelines. If the pipeline pressure control valve is directly fixed in the solar water heating system, it will also cause the installation space of the pipeline to be occupied, which is not conducive to the rapid installation of the pipeline. If the pipeline pressure control valve is suspended, although it can avoid the pipeline pressure control valve occupying the installation space, the pipeline pressure control valve will shake, and the stability of the connection between the pipeline and the pipeline pressure control valve cannot be guaranteed. The end of the connection between the pipeline and the pipeline pressure control valve is prone to loosening. Summary of the invention

[0019] A groove 22 is provided at the center of the left side wall of the suspension seat plate 7; a plurality of evenly distributed fastening screw holes 23 are provided on the left end face of the fixing seat 6; a plurality of through holes 24 which are connected with the fastening screw holes 23 are provided at the bottom of the groove 22; the fastening screw 8 passes through the through hole to the right and is screwed into the fastening screw hole 23, and the head of the fastening screw 8 fits with the bottom of the groove 22.

[0020] The upper outer wall of the middle portion of the valve body 1 is provided with an exhaust valve 25 which is in communication with the inner space thereof.

[0021] The right end of the valve body 1 is provided with a right ball valve 26 which is in communication with the internal space thereof; the right end of the right ball valve 26 is provided with a water outlet joint 27; the water outlet joint 27 is externally threadedly connected with a sealing cover 28 which matches the water outlet joint 27.

[0022] The water outlet joint 27 is an annular limiting groove 29; a limiting sleeve 30 matching therewith is arranged in the limiting groove 29; the limiting sleeve 30 is connected with an anti-slip belt 31; a clamping hole 32 is arranged at the free end of the anti-slip belt 31; a screw hole 33 corresponding to the position of the clamping hole 32 is arranged at the center of the right side wall of the sealing cover 28; a screw rod 34 matching therewith is screwed in the screw hole 33; the right end of the screw rod 34 passes through the clamping hole 32 to the right and is provided with a limiting head 35 that fits with the right side wall of the anti-slip belt 31.

[0023] The method of using the utility model is as follows:

[0024] Generally, there is a wall at the location where the solar water heating system is placed. In this case, it is only necessary to set a number of holes corresponding to the positions of the fixing holes 9 on the wall, and then embed the corresponding screw holes in the holes, and finally process the screw holes on the screw holes, so that the screws can be passed to the left through the fixing holes 9 and then screwed into the screw holes. At the same time, the head of the screw is pressed on the right side wall of the hanging seat plate 7, so that the hanging seat plate 7 can be fixed to the wall, thereby suspending the valve body 1 of the pipeline pressure control valve in mid-air while ensuring the stability of the valve body 1, effectively avoiding the shaking of the valve body 1 when multiple pipelines are connected to the upper ball valve 2 and the lower ball valve 3 on the valve body 1, and effectively ensuring the stability of the pipeline pressure control valve when connecting multiple pipelines, thereby avoiding the situation that the end of the pipeline used for connection falls off due to the shaking of the pipeline pressure control valve. When the valve body 1 is suspended in mid-air, it can effectively avoid the situation that the valve body pipeline pressure control valve occupies the installation space of multiple pipelines in the solar water heating system, which is beneficial to the layout and installation of multiple pipelines.

[0025] In the process of actually fixing the hanging seat plate 7, it is very easy to encounter the situation that the wall is uneven, or there are grooves and protrusions on the wall. Once the best fixing position of the hanging seat plate 7 exists in this situation, the hanging seat plate 7 cannot be firmly fixed to the wall by screws alone. At this time, the auxiliary seat plate 11 can be used to fix the hanging seat plate 7. First, two fixing surfaces are selected in the uneven position. One fixing surface makes the left side wall of the hanging seat plate 7 fit with it, and the other fixing surface makes the left side wall of the auxiliary seat plate 11 fit with it. The auxiliary seat plate 11 can adjust the position of its own left side wall according to actual needs. When the position of the left side wall of the auxiliary seat plate 11 needs to be adjusted, the left adjusting screw can be rotated. The nut 18 and the right adjusting nut 17, as the positions of the left adjusting nut 18 and the right adjusting nut 17 on the guide rod 15 change, the distance between the auxiliary seat plate 11 and the adjusting plate 13 will also change accordingly, thereby effectively adjusting the position of the left side wall of the auxiliary seat plate 11, and when adjusting the auxiliary seat plate 11, the guide rod 15 and the guide rail 21 can play a guiding role to ensure the flatness of the left side wall of the auxiliary seat plate 11, thereby ensuring that the left side wall of the auxiliary seat plate 11 is always parallel to the left side wall of the suspension seat plate 7, and at the same time, the guide rod 15 and the guide rail 21 can support the auxiliary seat plate 11 to ensure the stability of the auxiliary seat plate 11 after the position adjustment is completed.

[0026] When the position adjustment of the auxiliary seat plate 11 is completed, a screw hole corresponding to the auxiliary hole 19 can be processed on the wall, and then a new screw can be passed through the auxiliary hole 19 and screwed into the screw hole. The head of the new screw is pressed on the right side wall of the auxiliary seat plate 11. As the auxiliary seat plate 11 and the hanging seat plate 7 are both fixed to the wall by screws, when the auxiliary seat plate 11 and the hanging seat plate 7 are fixed, when the left side wall of the hanging seat plate 7 is in contact with a fixed surface on the wall, a restriction can be formed. When the left side wall of the auxiliary seat plate 11 is in contact with another fixed surface on the wall, another restriction can be formed. The existence of the two restrictions can effectively ensure stability. Even if the wall itself is uneven, there will be no shaking, thereby ensuring that the pipeline pressure control valve can be stably fixed and hung on the wall facing an uneven wall.

[0027] A groove 22 is provided in the center of the left side wall of the suspension seat plate 7, and a plurality of evenly distributed fastening screw holes 23 are provided on the left end face of the fixing seat 6. A plurality of through holes 24 which are connected with the fastening screw holes 23 are provided at the bottom of the groove 22. The fastening screw 8 passes through the through holes to the right and is screwed into the fastening screw hole 23. The head of the fastening screw 8 fits with the bottom of the groove 22. This fixing method can not only ensure the stability between the suspension seat plate 7 and the valve body 1, but also facilitates the disassembly and assembly of the suspension seat plate 7, and is convenient for the maintenance and replacement of the suspension seat plate 7.

[0028] An exhaust valve 25 communicating with the inner space of the valve body 1 is disposed on the upper outer wall of the middle portion of the valve body 1 . The exhaust valve 25 can achieve the effect of automatic exhaust and pressure reduction when the pressure in the valve body 1 is too high.

[0029] A right ball valve 26 which is connected to the internal space of the valve body 1 is provided at the right end, and a water outlet joint 27 is provided at the right end of the right ball valve 26. A sealing cover 28 which matches the water outlet joint 27 is screwed externally. The right ball valve 26 can be used to assist in connecting other pipelines and can also be used for sewage discharge. By simply unscrewing the sealing cover 28 from the water outlet joint 27 and then opening the right ball valve 26, the sewage cleaned from the inside of the solar water heating system can be discharged to the outside, thereby achieving a sewage discharge effect.

[0030] The water outlet joint 27 is an annular limiting groove 29, and a limiting sleeve 30 matching therewith is provided in the limiting groove 29, and an anti-slip band 31 is connected to the limiting sleeve 30, and a clamping hole 32 is provided at the free end of the anti-slip band 31, and a screw hole 33 corresponding to the position of the clamping hole 32 is provided at the center of the right side wall of the sealing cover 28, and a screw rod 34 matching therewith is screwed in the screw hole 33, and the right end of the screw rod 34 passes through the clamping hole 32 to the right and is provided with a limiting head 35 that fits the right side wall of the anti-slip band 31. The existence of the sealing cover 28 can not only play a dust-proof effect, but also prevent external impurities from entering the water outlet joint 27 and causing the inside of the valve body 1 to be contaminated, and the existence of the anti-slip band 31 can prevent the sealing cover 28 from being lost after it is screwed out from the water outlet joint 27. When it is necessary to completely disassemble the sealing cover 28, it is only necessary to screw the screw rod out of the screw hole 33 through the limiting head 35, and the sealing cover 28 is no longer restricted by the anti-slip band 31, so that the sealing cover 28 can be completely disassembled.

[0031] An auxiliary connector 4 which is in communication with the internal space of the valve body 1 is provided on the lower right outer wall of the valve body 1. The auxiliary connector 4 can be used to connect to a solar pressure tank, which can balance the pressure of the solar water heating system. The auxiliary connector 4 can also be used to connect to a thermometer, which is convenient for real-time understanding of the water flow temperature in the valve body 1.
