Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a full-seat rotary drum pneumatic drainage valve with good anti-leakage and anti-splashing effects. Background Art

[0002] A valve is a mechanical device that controls the flow, direction, pressure, temperature, etc. of a flowing fluid medium. A valve is a basic component in a piping system. Valve fittings are technically the same as pumps and are often discussed as a separate category. Valves can be operated manually or with a handwheel, handle or pedal, and can also be controlled to change the pressure, temperature and flow of the fluid medium.

[0003] At present, during the use of pneumatic drain valves, although they have good conveying effects for conveying most liquids, since most liquids contain impurities, in order to ensure a good anti-clogging effect when the valve body is used, a filter is usually used to collect the impurities. However, most of the filters are usually fixed with bolts and external auxiliary tools when docking with the valve body. The disadvantage of this method is that the operation is relatively complicated, and it is not conducive to forming a good sealing effect for the pipe body and the plate body connected to the filter, which leads to the disadvantage of leakage of the valve body during use, and further causes problems such as the accuracy of the valve body. Therefore, a whole-seat rotary drum pneumatic drain valve with good anti-leakage and anti-splashing effects is proposed to solve the above problems. Utility Model Content

[0005] To achieve the above object, the utility model provides the following technical solution: a full-seat rotary drum pneumatic drain valve with good anti-leakage and anti-splashing effects, comprising a valve body, a connecting pipe is connected to the valve body, and a filter is arranged on the inner side of the valve body;

[0006] The valve body comprises a valve channel, a guide frame is fixedly connected to the outer side of the valve channel, a valve frame is fixedly connected to the outer side of the guide frame, a cylinder is fixedly installed at the end of the valve frame, an output end of the cylinder is fixedly connected to a partition plate having one end penetrating the guide frame and extending to the inner side of the valve channel, a mounting seat is fixedly connected to the lower end of the valve channel, and a connecting seat is fixedly connected to the outer sides of the valve channel and the connecting pipe;

[0007] The filter element includes a retaining ring whose one end is fixedly connected to the upper end of the valve channel and extends to the inside of the connecting pipe, a supporting ring is inserted between the retaining ring and the connecting pipe, the lower end of the supporting ring is fixedly connected to a connecting frame, and the inner side of the connecting frame is fixedly connected to a filter screen.

[0008] Furthermore, the end of the connecting pipe close to the valve channel is provided with grooves respectively located outside the retaining ring and the supporting ring.

[0011] Furthermore, the connecting frame is composed of a plurality of elastic sheets and connecting sheets, and the plurality of elastic sheets and connecting sheets are fixedly connected end to end in sequence.

[0012] Furthermore, the elastic sheet is a hard rubber sheet, and the connecting sheet is a steel sheet.

[0013] Furthermore, mounting holes are provided at the four corners of the mounting seat and inside the connecting seat.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] 1. The whole-seat rotary drum pneumatic drain valve with good anti-leakage and anti-splashing effects has a whole-seat structure for both the water inlet and the water outlet on the entire valve body (that is, it is connected to the mounting seat through a connecting seat). The function of the whole-seat structure is to reduce the leakage points caused by the use of separate seats to avoid leakage. At the same time, the discharged water is sent to the inside of the water collection tank through the connecting pipe without splashing everywhere, so as to improve the airtightness of the entire valve body.

[0016] 2. The whole-seat rotary drum pneumatic drain valve has good anti-leakage and anti-splashing effects. When the connecting pipe and the valve channel are assembled through the connecting seat, the support ring can be installed and fixed between the retaining ring and the connecting pipe. At the same time, the filter screen located on the inner side of the connecting frame can filter impurities in the water flow. When the water flows, pressure is generated on the recessed part of the connecting frame to drive the connecting frame to tightly contact the inner wall of the valve channel and the inner side of the support ring groove, thereby further improving the airtightness of the connection between the valve channel and the connecting pipe.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0023] See also Figure 1-2 In this embodiment, a complete rotary drum pneumatic drain valve with good anti-leakage and anti-splashing effects comprises a valve body 1, a connecting pipe 2 is connected to the valve body 1, and a filter element 3 is arranged inside the valve body 1;

[0024] The valve body 1 includes a valve channel 11, the outer side of the valve channel 11 is fixedly connected to a guide frame 12, the outer side of the guide frame 12 is fixedly connected to a valve frame 13, the end of the valve frame 13 is fixedly installed with a cylinder 14, the output end of the cylinder 14 is fixedly connected to a partition 17 whose end passes through the guide frame 12 and extends to the inner side of the valve channel 11, the lower end of the valve channel 11 is fixedly connected to a mounting seat 16, and the outer sides of the valve channel 11 and the connecting pipe 2 are both fixedly connected to a connecting seat 15.

[0025] In this embodiment, on the whole valve body 1, on the one hand, the water inlet and the water outlet are all of an integral seat structure, that is, they are connected to the mounting seat 16 through a connecting seat 15. The function of the integral seat is to reduce the leakage points caused by the use of a separate seat, thereby avoiding leakage. At the same time, the discharged water is sent to the inside of the water collection tank through the connecting pipe 2 without splashing everywhere, so as to improve the airtightness of the whole valve body 1.

[0026] It should be noted that mounting holes are provided at the four corners of the mounting seat 16 and inside the connecting seat 15 .

[0027] See also Figure 2-4 In this embodiment, the filter element 3 includes a retaining ring 36 whose one end is fixedly connected to the upper end of the valve channel 11 and extends to the inside of the connecting pipe 2. A support ring 31 is inserted between the retaining ring 36 and the connecting pipe 2. The lower end of the support ring 31 is fixedly connected to a connecting frame 32, and the inner side of the connecting frame 32 is fixedly connected to a filter screen 33.

[0028] In this embodiment, the support ring 31 can be installed and fixed between the retaining ring 36 and the connecting pipe 2, and the filter 33 located on the inner side of the connecting frame 32 can filter impurities in the water flow. When the water flows, pressure will be generated on the recessed part of the connecting frame 32, so as to drive the connecting frame 32 to tightly contact the inner wall of the valve channel 11 and the inner side of the groove 34 of the support ring 31, thereby further improving the airtightness of the connection between the valve channel 11 and the connecting pipe 2.

[0029] The end of the connecting pipe 2 close to the valve channel 11 is provided with a groove 34 located outside the retaining ring 36 and the support ring 31 respectively. The groove 34 is connected to the retaining ring 36 and can also support and fix the support ring 31.

[0030] In addition, sealing rings 35 are embedded in the upper ends of the retaining ring 36 and the support ring 31 , and the inner diameter of the groove 34 is matched with the outer diameter of the retaining ring 36 , so that the connecting pipe 2 can fit tightly with the retaining ring 36 .

[0031] Secondly, the connecting frame 32 is cylindrical, and the middle part of the connecting frame 32 is concave, so that the concave part of the connecting frame 32 can be impacted by the water flow.

[0032] Then, the connecting frame 32 is composed of a number of elastic sheets 321 and connecting sheets 322, which are fixedly connected end to end in sequence, so that after the elastic sheets 321 and connecting sheets 322 connected end to end form a ring, they can fit with the retaining ring 36 and the inner wall of the valve channel 11.

[0033] Finally, the elastic sheet 321 is a hard rubber sheet, and the connecting sheet 322 is a steel sheet. When the thin sheet and the hard rubber sheet just made are subjected to the impact force of the water flow, they are deformed and can fit tightly with the valve channel 11 and drive the support ring 31 and the inner wall of the groove 34.

[0034] The working principle of the above embodiment is:

[0035] On the whole valve body 1, on the one hand, both the water inlet and the water outlet are of an integral seat structure, that is, they are connected to the mounting seat 16 through a connecting seat 15. The function of the integral seat is to reduce the leakage points that are more than the separate seat type, thereby avoiding leakage. At the same time, the discharged water is sent directly to the inside of the sump through the connecting pipe 2 without splashing everywhere, so as to improve the airtightness of the whole valve body 1. When the connecting pipe 2 and the valve channel 11 are assembled through the connecting seat 15, the support ring 31 can be installed and fixed between the retaining ring 36 and the connecting pipe 2. At the same time, the filter screen 33 located on the inner side of the connecting frame 32 can filter impurities in the water flow. When the water flows, pressure will be generated on the recessed part of the connecting frame 32, so as to drive the connecting frame 32 to tightly contact the inner wall of the valve channel 11 and the inner side of the groove 34 of the support ring 31, thereby further improving the airtightness of the connection between the valve channel 11 and the connecting pipe 2.
