The built-in valve comprises a valve body, a valve clack and a valve rod, wherein the valve clack is arranged in the valve body, one end of the valve rod is connected with the valve clack, and the other end of the valve rod is connected with the connecting rod.
The external cylinder comprises a cylinder body, a piston rod and a cylinder head, wherein the piston rod is arranged in the cylinder body, and the cylinder head is arranged at the end part of the cylinder body.
The cylinder body is provided with an air inlet and an air outlet.
The internal valve and the external cylinder are made of corrosion-resistant materials.
Compared with the prior art, the utility model has the beneficial effects that:
1. According to the utility model, the air cylinder is arranged outside the chemical tank, so that the air cylinder is prevented from being corroded by chemical materials, the service life of the air cylinder is prolonged, the external air cylinder is connected with the internal valve through the connecting mechanism, the remote control of the internal valve is realized, the operation is convenient, and the maintenance is simple.
2. According to the utility model, the sealing sleeve is arranged on the connecting structure, so that the sealing performance of the chemical tank is ensured, and the leakage of materials is prevented.
Drawings
Fig. 1 is a schematic diagram of the structure of the present utility model.
Fig. 2 is a schematic diagram of a second embodiment of the present utility model.
In the figure, a chemical tank 1, an internal valve 2, an external cylinder 3, a connecting rod 4, a sealing sleeve 5, a discharge hole 6, a valve body 7, a valve clack 8, a valve rod 9, a cylinder body 10, a piston rod 11, a cylinder cover 12, an air inlet 13, an air outlet 14, a protective baffle tube 15, a clamp one 16, a clamp two 17, a sealing plate 18, an inverted tooth 19 and an inverted tooth 20 are shown.
Detailed Description
The utility model is described in further detail below with reference to the accompanying drawings and detailed description.
Referring to fig. 1-2, a chemical tank built-in valve control device comprises a chemical tank 1, wherein a discharge hole 6 is formed in a tank body of the chemical tank 1, an internal valve 2 is installed at the discharge hole 6, the internal valve 2 is installed in the chemical tank 1, an external cylinder 3 is arranged outside the chemical tank 1, the internal valve 2 and the external cylinder 3 are made of corrosion-resistant materials, and the external cylinder 3 is in transmission connection with the internal valve 2 through a connecting mechanism. The external cylinder 3 is externally sleeved with the protection baffle pipe 15, so that the protection baffle pipe 15 can be detachably designed for facilitating maintenance and overhaul of the device, and an operator can easily detach the protection baffle pipe 15 to check, repair and replace internal parts.
The connecting mechanism comprises a connecting rod 4 and a sealing sleeve 5, one end of the connecting rod 4 is connected with a valve rod of the built-in valve 2, the other end of the connecting rod 4 penetrates through a tank body of the chemical tank 1 to be connected with a piston rod of the external cylinder 3, the sealing sleeve 5 is arranged at the joint of the connecting rod 4 and the tank body of the chemical tank 1, the sealing sleeve 5 is sleeved on an inverted tooth 19 and an inverted tooth 20 and is respectively fixed by a clamp one 16 and a clamp two 17, the inverted tooth 20 is welded with the tank body of the chemical tank 1, a sealing plate 18 is welded with the inverted tooth 19, and chemical media are prevented from entering the sealing sleeve 5.
The built-in valve 2 comprises a valve body 7, a valve clack 8 and a valve rod 9, wherein the valve clack 8 is arranged in the valve body 7, one end of the valve rod 9 is connected with the valve clack 8, and the other end of the valve rod 9 is connected with the connecting rod 4.
The outboard cylinder 3 includes a cylinder block 10, a piston rod 11, and a cylinder head 12, the piston rod 11 being disposed within the cylinder block 10, the cylinder head 12 being disposed at an end of the cylinder block 10. The cylinder body 10 is provided with an air inlet 13 and an air outlet 14, and the movement of the piston rod 11 is controlled through the air inlet and the air outlet, so that the valve clack 8 of the built-in valve 2 is driven to be opened and closed.
In the actual use process, when the internal valve 2 needs to be closed, the piston rod of the external cylinder 3 stretches out, and the connecting rod 4 drives the valve rod of the internal valve 2 to move, so that the internal valve 2 is closed, and the outflow of materials in the chemical tank 1 is cut off. When the built-in valve 2 needs to be opened, the piston rod of the external cylinder 3 contracts, and the connecting rod 4 drives the valve rod of the built-in valve 2 to move, so that the built-in valve 2 is opened, and materials in the chemical tank 1 can smoothly flow out.
