Abstract

The utility model provides a seal gasket which comprises a framework and a seal part. The framework is made of metal materials. The seal part is butt connected and bonded on the framework in parallel by the glue. The seal part is thicker than the framework which is provided with a screw used for arranging. By adopting the structure of the utility model, the close contact between the whole seal gasket and the seal cover is guaranteed, the seal performance is good. The seal part is made of fluorin rubber and has good aging resistance. The metal framework in the seal gasket can be recyclable. Less rubber is used in the seal part. The raw edges in the operation process are less, thereby causing less waste, not only reducing the cost, but also being beneficial to the environment protection.

Description

Gasket seal

Technical field

The utility model belongs to technical field of sealing technology, is specifically related to a kind of sealing gasket of automobile engine oil dish lower body.

Technical background

The sealing of the automobile engine oil dish lower body that uses now, mostly be to adopt by the stamping forming sealing gasket of Ashestos plate, because this material is softer, bad mechanical strength, fragile during the screw rod extruding, to be sealed yielding, thereby sealing is poor, and this material belongs to non-feature of environmental protection material, and is toxic in making, using, and extremely difficult the decomposition, can not recycle.In addition, also adopt other sealing material, as softer metals such as copper, aluminium, though mechanical strength is higher, resilience is very poor, does not reach seal request equally.Can also coat the rubber-like sealing material with sheetmetal and make gasket seal, existing higher mechanical strength has the better seal effect again, but needs the manufacturing of special tool mould, cost height.

The model utility content

The purpose of this utility model is the defective that exists at existing sealing gasket, provides a kind of screw rod extruding back sealing surface not yielding, good airproof performance, and ageing resistance is good, can adapt to than elevated operating temperature the sealing gasket that cost is low.

In order to realize this purpose, the utility model provides a kind of gasket seal, is made up of skeleton and sealed department, sealed department is slightly thicker than skeleton, sealed department by the adhesive parallel docking be bonded on the skeleton, skeleton is made by metallic material, has the screw that usefulness is installed on the skeleton.Sealed department is made by rubber.Skeleton and sealed department can be made arbitrarily and treatment sealing surface shape adapting.

After adopting structure of the present utility model, because the skeleton of Sealing is by the metallic material manufacturing, bolt hole is opened on skeleton, the screw rod extruding can be out of shape during work, and sealed department is slightly thicker than skeleton, and pressurized is uniform and stable during work, guaranteed tight contact the between whole sealing gasket and the sealing surface, sealing is good.Sealed department fluorine rubber manufacturing, operating temperature allow to reach 120 ℃-200 ℃, short-term even allow to reach 300 ℃, and ageing resistance is good.In the gasket seal, the recyclable utilization of metal frame, the rubber of sealed department uses few, and the work in-process burr are few, wastes for a short time, has not only reduced cost, also helps environmental protection.

Description of drawings

Fig. 1 is the cross-sectional view of sealing gasket.

Embodiment

As shown in Figure 1, skeleton 1 is to be made by the metallic material that steel, iron, copper or aluminum alloy etc. have a higher mechanical strength, and thickness is 1-2.5mm, has screw 2 on it.Sealed department 3 usefulness adhesives 5 and skeleton 1 parallel being bonded together, make preferably by synthetic rubber or synthetic resin by oil resistant, heatproof, water resistance for adhesive 5.Sealed department 3 can be with all kinds of synthetic rubber manufacturings, as: butyl rubber, styrene butadiene rubber, nitrile butadiene rubber, fluorine rubber, neoprene, silicone rubber, Thiokol, polyurethane rubber, isoprene rubber are good with fluorine rubber.Sealed department thickness is 1.5-3.5mm, and width is 2.5-6mm.In order to improve sealability, on the two sides at the close skeleton place of sealed department one groove 4 is arranged all, groove 4 wide 0.5-0.8mm, dark 0.5-1mm.Sealing gasket can be made arbitrarily and to be sealed shape adapting.

Above embodiment is in order to help to understand better the utility model, and the utility model is not limited to above embodiment, also has other embodiment in the utility model purport and scope.

Claims

1. gasket seal is become with the sealing ministerial level by skeleton, and it is characterized in that: skeleton is made by metallic material, sealed department by the adhesive parallel docking be bonded on the skeleton, sealed department is slightly thicker than skeleton, has the installation screw on the skeleton.

2. the described gasket seal of claim 1, it is characterized in that: sealed department is a rubber.

3. the described gasket seal of claim 2, it is characterized in that: sealed department is a fluorine rubber.

4. the described gasket seal of claim 1, it is characterized in that: skeleton and sealed department are made and to be sealed shape adapting.

5. the described gasket seal of claim 4 is characterized in that: sealed department all has groove near the two sides at skeleton place.
