Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of radiators, in particular to the field of drain valves of radiators, and specifically refers to a double rubber pad drain valve. Background Art
[0002] The drain valve of the car radiator is installed on the water chamber to discharge the coolant in the water chamber. The drain valve is threadedly connected to the water chamber. The traditional drain valve has only one layer of rubber pad and poor sealing performance. The coolant in the water chamber only passes through this layer of seal and there is still water seepage. In addition, most of the original drain valves do not have an anti-falling structure. Therefore, when installing and disassembling the drain valve, it is easy for the drain valve to fall off, causing inconvenience to the operation. In addition, the detached drain valve is easily contaminated with impurities, affecting the cleanliness of the inner cavity of the radiator, thereby affecting the quality of the product. Utility Model Content
[0003] The utility model aims at the deficiencies of the prior art and provides a double rubber pad drain valve.
[0004] The utility model is realized through the following technical scheme, and provides a double rubber pad drain valve, comprising an end plate, a threaded section, a large diameter section and a small diameter section which are integrally connected in sequence, wherein the outer diameters of the end plate, the threaded section, the large diameter section and the small diameter section decrease in sequence, an external thread is provided on the threaded section, a large diameter sealing ring is installed on the large diameter section, and a small diameter sealing ring is installed on the small diameter section.
[0005] When this solution is in use, the double rubber pad drain valve is fastened to the radiator water chamber by a threaded section, and a large-diameter sealing ring and a small-diameter sealing ring are used to achieve double-layer sealing on both sides of the drain port between the radiator water chamber and the drain valve, thereby greatly improving the sealing effect.
[0006] As an optimization, an end of the small diameter section away from the large diameter section is fixedly connected with an anti-detachment hook. When draining water, the anti-detachment hook can be hooked on the water chamber to prevent the drain valve from detaching from the water chamber and avoiding loss.
[0007] As an optimization, the distance from the hook head of the anti-detachment hook to the center of the small-diameter section is greater than the radius of the small-diameter section, thereby improving the anti-detachment effect of the anti-detachment hook.
[0008] As an optimization, a rotating operating plate is fixedly connected to one end of the end plate away from the threaded section, and the rotating operating plate is perpendicular to the end plate. The rotating operating plate provided in this solution is perpendicular to the end plate, and the entire drain valve can be rotated by pinching the rotating operating plate.
[0009] As an optimization, a large diameter sealing ring groove adapted to the large diameter sealing ring is opened on the large diameter section, thereby limiting the axial movement of the large diameter sealing ring.
[0010] As an optimization, a small-diameter sealing ring groove adapted to the small-diameter sealing ring is opened on the small-diameter section, thereby limiting the axial movement of the small-diameter sealing ring.
[0011] As an optimization, the outer circle of one end of the threaded section close to the large diameter section is chamfered, so that the threaded section is pressed tightly into the stepped hole through the chamfer, thereby improving the sealing effect.
[0012] The beneficial effects of the utility model are as follows: a double rubber pad drain valve of the utility model, a large-diameter sealing ring and a small-diameter sealing ring are used between the radiator water chamber and the drain valve to achieve double-layer sealing on both sides of the drain outlet, the sealing effect is greatly improved, and water seepage is effectively prevented. The utility model has the advantages of simple processing technology, low production cost, strong sealing effect, easy operation and high production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.
[0019] like Figures 1 to 3 As shown, a double rubber pad drain valve of the utility model comprises an end plate 1, a threaded section 2, a large diameter section 3 and a small diameter section 5 which are integrally connected in sequence. The end plate 1, the threaded section 2, the large diameter section 3 and the small diameter section 5 are integrally formed plastic parts, and each part is a cylindrical structure.
[0020] The outer diameters of the end plate 1, the threaded section 2, the large diameter section 3 and the small diameter section 5 decrease in sequence. A stepped hole corresponding to the drain valve is opened on the water chamber. The diameter of the stepped hole gradually increases from the inside to the outside, corresponding to the small diameter section 5, the large diameter section 3 and the threaded section 2, respectively. The threaded section 2 is provided with an external thread, which is threadedly connected with the stepped hole, thereby realizing the tightening operation of the entire drain valve. The outer circle of the threaded section 2 is chamfered at one end close to the large diameter section 3. The chamfer is pressed tightly at the stepped position of the stepped hole, which can improve the sealing effect here.
[0021] The large diameter section 3 is provided with a large diameter sealing ring 4, and the large diameter section 3 is provided with a large diameter sealing ring groove adapted to the large diameter sealing ring 4. The small diameter section 5 is provided with a small diameter sealing ring 6, and the small diameter section 5 is provided with a small diameter sealing ring groove adapted to the small diameter sealing ring 6.
[0022] An anti-drop hook 7 is fixedly connected to one end of the small diameter section 5 away from the large diameter section 3. The anti-drop hook can be a plastic part integrally formed with the small diameter section 5, or a fixed metal part. The distance from the hook head of the anti-drop hook 7 to the center of the small diameter section 5 is greater than the radius of the small diameter section 5, so that when the drain valve is rotated outward, the anti-drop hook 7 is hooked in the water chamber to prevent it from falling out and being lost.
[0023] A rotating operating plate 8 is fixedly connected to one end of the end plate 1 away from the threaded section 2, and the rotating operating plate 8 is perpendicular to the end plate 1. The entire drain valve can be rotated by pinching the rotating operating plate.
[0024] The use of the utility model:
[0025] like Figure 2 As shown, in the use state, the double rubber pad drain valve has threads, which are fastened to the radiator water chamber through the threads. The radiator water chamber and the drain valve are double-layer sealed on both sides of the drain port through the large diameter sealing ring 4 and the small diameter sealing ring 6, and the sealing effect is greatly improved.
[0026] When draining water, rotate the double rubber pad drain valve to Figure 3 In the state, the water in the water chamber is discharged through the drain port at the lower end. An anti-detachment hook is provided at one end of the drain valve. When draining water, the anti-detachment hook can be hooked on the water chamber to prevent the drain valve from detaching from the water chamber and avoiding loss.
