Detailed Description
Example 1: referring to fig. 1-2, a sheet valve type diaphragm pump comprises a pump body 1, a feeding pipeline 2 and a discharging pipeline 3, wherein a transition cavity 4 is arranged below the pump body 1, a left cavity 41 and a right cavity 42 which are mutually separated are arranged in the transition cavity 4, the left cavity 41 of the transition cavity 4 is communicated with a left pump cavity 11 of the pump body 1, the right cavity 42 of the transition cavity 4 is communicated with a right pump cavity 12 of the pump body 1, the feeding pipeline 2 is communicated with one side of the transition cavity 4 through a feeding valve 21, and the discharging pipeline 3 is communicated with the other side of the transition cavity 4 through a discharging valve 31.
In this embodiment, the pump body 1 is provided with diaphragms in both the left pump chamber 11 and the right pump chamber 12, when the diaphragm pumps are started, the diaphragms in the left pump chamber 11 and the right pump chamber 12 are driven to move left and right, as shown in fig. 1-2, when the diaphragms move left, the left pump chamber 11 discharges fluid to the discharge pipe 3 through the left chamber 41 of the transition chamber 4, the right pump chamber 12 sucks fluid to the feed pipe 2 through the right chamber 42 of the transition chamber 4, when the diaphragms move right, the right pump chamber 12 discharges fluid to the discharge pipe 3 through the right chamber 42 of the transition chamber 4, and the left pump chamber 11 sucks fluid to the feed pipe 2 through the left chamber 41 of the transition chamber 4; wherein, the above-mentioned feed conduit 2 communicates one side of left cavity 41 and right cavity 42 of transition chamber 4 through feed valve 21, arrange the opposite side of left cavity 41 and right cavity 42 that the conduit 3 communicates transition chamber 4 through relief valve 31, and feed valve 21 and relief valve 31 are the check valve, and feed valve 21 only holds fluid and gets into left cavity 41 and right cavity 42 of transition chamber 4 from feed conduit 2, and relief valve 31 only holds fluid and gets into the relief conduit 3 from left cavity 41 and right cavity 42 of transition chamber 4. In the use process of the embodiment, the fluid mainly enters the discharge pipeline 3 from the feeding pipeline 2 through the transition cavity 4, so that the abrasion of the fluid on the diaphragm in the pump body is reduced, and when the pump body pumps the fluid, the fluid can easily enter the transition cavity 4 from the left pump cavity 11 or the right pump cavity 12 of the pump body 1 and be discharged under the action of gravity, and cannot be accumulated in the pump body 1.
Referring to FIG. 3, in a further embodiment, both the inlet valve 21 and the outlet valve 31 are of a flap-valve type construction; the sheet valve type structure comprises a fixing plate 51 and two rubber sheets 52, wherein a left opening 53 and a right opening 54 are formed in the fixing plate 51, the two rubber sheets 52 are fixedly arranged on one side of the fixing plate 51, and the two rubber sheets 52 cover the left opening 53 and the right opening 54 respectively. In particular, the rubber sheet 52 of the inlet valve 21 is arranged on the side close to the transition chamber 4 so that fluid can only enter the transition chamber 4 from the inlet conduit 2, and the rubber sheet 52 of the outlet valve 31 is arranged on the side close to the outlet conduit 3 so that fluid can only enter the outlet conduit 3 from the transition chamber 4. The use of the sheet valve type structure for the feed valve 21 and the discharge valve 31 allows the passage of fluid of larger particles, and the fluid is less likely to stagnate at the feed valve 21 and the discharge valve 31.
In a further embodiment, the transition chamber 4 is provided with a left opening 43 and a right opening 44 at two ends, the left cavity 41 of the transition chamber 4 is communicated with the left pump cavity 11 of the pump body 1 through the left opening 43, the right cavity 42 of the transition chamber 4 is communicated with the right pump cavity 12 of the pump body 1 through the right opening 44, the height of the left opening 43 is lower than that of the left cavity 41, and the height of the right opening 44 is lower than that of the right cavity 42. For the fluid with the floating objects, after the fluid enters the transition cavity 4 from the feeding pipeline 2, the fluid floats in the transition cavity 4, and the floating objects cannot enter the pump body 1 in the conveying process and can be conveyed out smoothly because the heights of the left cavity 41 and the right cavity 42 of the transition cavity 4 are higher than the heights of the left opening 43 and the right opening 44; thereby accommodating the delivery of more fluid.
Further, the feed pipe 2 and the discharge pipe 3 are connected to the transition chamber 4 via flange heads. The flange head is adopted for connection, so that the connection strength of the connection part can be improved, the stability of fluid conveying is improved, and the diaphragm pump is convenient to install, disassemble and clean.
Of course, the above is only the preferred embodiment of the present invention, and the application range of the present invention is not limited thereto, so all the equivalent changes made in the principle of the present invention should be included in the protection range of the present invention.
