Secondary property is to compressing on the back of exhaust manifold big face two.
Described support, gripper shoe are all packed on clamp body.
The present invention, when using, need to by exhaust manifold with little flange be forward-facing placed on cushion block in face-down greatly mode,
And two connecting holes on exhaust manifold are attached with two straight pins, realize two-point locating.Now, on the big face of exhaust manifold
The little mouth of pipe sealed by four sealing rings, and enable the passage port on cushion block of pipe joint to connect exhaust manifold
Any one little mouth of pipe on big face.
Then the hex nut passing through to rotate on each clamping and fixing device and No. two clamping and fixing devices will be pressed
Block presses to exhaust manifold big face back, exhaust manifold is compressed, has the effect of leakproof.
Under this state, jackscrew withstands the rear end of exhaust manifold, finally just can be by rotary screw so that plug is moved rearwards by
Until the big mouth of pipe on little for exhaust manifold flange face is blocked.
When carrying out leak test test, only need to be by gas, Ran Houzai be passed through by pipe joint to the inside of exhaust manifold
By detecting whether exhaust manifold air pressure inside changes to determine whether gas leakage.
The invention has the beneficial effects as follows：
The present invention is on the basis of by exhaust manifold by two-point locating moreover it is possible to effectively exhaust manifold is fixed pressure
Tightly, and fitted seal circle and plug seal to exhaust manifold.And then reach the effect conveniently carrying out ventilation side leakage.This
Outward, the present invention use easy to adjust, pneumatic sealing test effect is preferable.
