Description

Technical Field

[0001] The utility model relates to the technical field of water reducing agent filling, in particular to a flap valve module for water reducing agent filling. Background Art

[0002] Water reducer is an additive used in the production of concrete and cement products. It can effectively reduce the amount of cement and improve the fluidity and durability of concrete. In the filling process of water reducer, the flap valve module plays an important role. The flap valve module is mainly used to control the flow and stop of water reducer in the filling system to ensure accurate metering and filling of water reducer. The flow of water reducer is adjusted by controlling the opening and closing of the flap to ensure accurate flow control of water reducer during the filling process; when the filling of water reducer needs to be stopped, the flap valve module can close the flap to prevent the water reducer from continuing to flow, thereby ensuring the accuracy and stability of the production process, and can also effectively prevent the water reducer from leaking during the filling process, ensuring the cleanliness and safety of the production environment. Through precise flow control and filling stop function, the flap valve module can improve production efficiency, reduce waste and reduce production costs.

[0003] Most of the existing flap valve modules are single flaps, which are easily deformed and leak after being under pressure for a long time. Therefore, it is necessary to invent a flap valve module with reliable structure and good durability. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model develops a flap valve module for water reducing agent filling, which can effectively prevent the flap from deforming and improve the durability of the flap valve module.

[0005] The technical solution to the technical problem solved by the utility model is: a flap valve module for filling a water reducer, comprising a valve body, a flap, a rotating shaft, a sliding rod and a connecting rod, the flap being symmetrically arranged along the center of the valve body, the rotating shaft being rotatably connected to the valve body through a rotating bearing, the flap being rotatably connected to the rotating shaft through a rotating member, sliding grooves being arranged on both sides of the rotating shaft in the length direction of the valve body, the sliding rod being slidably connected in the sliding grooves, one end of the connecting rod being rotatably connected to the sliding rod, and the other end being rotatably connected to a rotating seat, and the rotating seat being connected to the flap.

[0006] Preferably, sealing blocks are connected to both ends of the slide rod, and the sealing blocks are also slidably connected in the slide groove.

[0007] Preferably, a transmission rod is connected to the sealing block, and an opening is provided on the valve body at the slide groove, and the transmission rod is slidably connected in the opening.

[0008] Preferably, a cylinder seat is provided on the valve body, a cylinder is connected to the cylinder seat, and an output end of the cylinder is connected to a transmission rod.

[0009] Preferably, the rotating parts are symmetrically arranged on both sides of the flap.

[0010] Preferably, connecting flanges are provided at both ends of the valve body along the through direction.

[0011] The effects provided in the utility model content are only the effects of the embodiments, not all the effects of the utility model. The above technical solution has the following advantages or beneficial effects:

[0012] 1. By setting the slide groove and the sealing block, the water reducing agent can be effectively prevented from leaking after the flap is opened;

[0013] 2. By symmetrically setting two flaps, the force can be better dispersed to prevent deformation caused by long-term pressure, thereby improving the durability of the valve body;

[0014] 3. The slide rod is pushed by the cylinder, and the slide rod drives the flap to rotate through the connecting rod to open and close. This method has a simple structure, easy replacement of parts, and low production cost;

[0015] 4. By arranging two rotating seats on a flap, the stability of the flap can be improved, and the pressure can be more even when there is a water reducer on the top, which is beneficial to extend the service life of the flap. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to clearly illustrate the technical features of the present invention, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0024] Example 1

[0025] See also Figures 1 to 6 A flap valve module for filling a water reducing agent comprises a valve body 1, a flap 2, a rotating shaft 3, a sliding rod 5 and a connecting rod 6. The flap 2 is symmetrically arranged along the center of the valve body 1. The rotating shaft 3 is rotatably connected to the valve body 1 through a rotating bearing. The flap 2 is rotatably connected to the rotating shaft 3 through a rotating member 4. Slide grooves 7 are arranged on both sides of the rotating shaft 3 on the valve body 1 in the length direction. The sliding rod 5 is slidably connected in the slide groove 7. One end of the connecting rod 6 is rotatably connected to the sliding rod, and the other end is rotatably connected to a rotating seat 21. The rotating seat 21 is connected to the flap 2.

[0026] like Figure 3 and Figure 4 As shown, sealing blocks 8 are connected to both ends of the slide rod, and the sealing blocks 8 are also slidably connected in the slide groove 7.

[0027] like Figure 3 and Figure 4 As shown, the sealing block 8 is connected with a transmission rod 9, the slide groove 7 is provided with an opening on the valve body 1, and the transmission rod 9 is slidably connected in the opening.

[0028] like Figure 1 and Figure 3 As shown, a cylinder 11 is provided on the valve body 1 , a cylinder 10 is connected to the cylinder seat 11 , and an output end of the cylinder 10 is connected to the transmission rod 9 .

[0029] like Figure 5 and Figure 6 As shown, the rotating member 4 is symmetrically arranged on both sides of the flap 2 .

[0030] like Figure 3 As shown, the valve body 1 is provided with connecting flanges 101 at both ends along the through direction.

[0031] Principle and operation process

[0032] The utility model adopts the method of pushing the sliding rod to control the opening or closing of the flap 2. When in use, first determine whether the valve body 1, the flap 2, the rotating shaft 3, the sliding rod 5 and the connecting rod 6 are intact, and pay attention to cleaning the debris in the sliding groove 7 to avoid affecting the sliding restriction of the sealing block 8 inside. When it needs to be opened, start the cylinder 10 to push the transmission rod 9, the transmission rod 9 drives the sealing block 8 to move downward, and the sealing block 8 then drives the sliding rod to push downward, and the sealing block 8 at the other end also slides downward in the sliding groove 7. The sliding rod pushes downward to drive one end of the connecting rod 6 to move downward, and the other end rotates on the rotating seat 21, thereby pulling the two flaps 2 to rotate downward to complete the opening operation. When it needs to be closed, the cylinder 10 retracts and pulls the transmission rod 9 to move upward, driving the sliding rod to move upward, pushing the flap 2 upward, and completing the closing operation.

[0033] Symmetrically arranging the two flaps 2 can better disperse the force transmitted by the water reducing agent raw material above, prevent leakage caused by deformation due to long-term pressure, and improve the durability of the valve body 1.

[0034] By providing the slide groove 7 in conjunction with the sealing block 8, the water reducer raw material can be effectively prevented from leaking after the flap 2 is opened. When the slide rod moves downward, a gap will be generated on the slide groove 7. By adding the sealing block 8, the sealing block 8 is driven to move downward when the slide rod moves downward. The sealing block 8 slides in the slide groove 7 and can seal the opening of the leaked part of the slide groove 7 when the flap 2 is opened, thereby preventing the water reducer raw material from leaking.

[0035] Although the specific implementation methods of the utility model are described above in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. On the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
