Preferably, the arc panel includes the first arc panel and the second arc panel, the second arc panel is close to second shell Setting, the thickness of the second arc panel are greater than the first arc panel, and the junction of the first arc panel and the second arc panel is bevel structure, The side of stiffening plate and bevel structure are cooperatively connected.

By using above scheme, the thickness of the second arc panel is greater than the thickness of the first arc panel, can increase first shell The intensity of body and second shell junction, junction are bevel structure, increase the contact area of stiffening plate and arc panel, are increased Both strong bonding strength.

Preferably, fixed in the first shell, there are two the bearing plate being located between two arc panels, bearing plates One end be fixedly connected on necking down plate.

By using above scheme, is set in first shell there are two the bearing plate between arc panel, can increase shell On the not no part of arc panel intensity, to enhance the integral strength of first shell.

Preferably, the bearing plate, which is installed with side far from one end of necking down plate, is fixedly connected on consolidating for first shell inner wall Fixed board, one end positioned at the stiffening plate of arc panel two sides are fixedly connected on bearing plate.

By using above scheme, fixed plate strengthens the bonding strength of bearing plate and first shell, bearing plate and arc It is fixedly connected between plate by stiffening plate, strengthens the bonding strength of bearing plate and arc panel, so that first shell, arc It is connected to each other between plate, stiffening plate, bearing plate and fixed plate, enhances the stability of each section connection.

Preferably, the stiffening plate is installed with limited block far from one end of necking down plate, the side of the limited block is fixed to be connected It is connected to arc panel.

By using above scheme, the surface due to being mounted on the intracorporal components of valve is arcuate structure, is being installed It when in first shell, can relatively rotate between two arcwall faces, it is therefore desirable to be installed with limit in one end of stiffening plate Block makes components match the relative rotation to limit it with annular slab with limited block equipped with groove.

Preferably, the two sides of the arc panel are set as arcuate structure, between the two sides and first shell of the arc panel There are recessing grooves.

By using above scheme, between the arcuate structure and first shell of arc panel two sides there are recessing groove, in valve In vivo installation components when, between arc panel and first shell there are recessing groove play the role of resigning, convenient for components Fast Installation.

Preferably, being uniformly installed with several reinforcing ribs along its axis direction in the first shell.

By using above scheme, reinforcing rib can improve the intensity of shell while reducing containment weight.

In conclusion the utility model has the following beneficial effects:

1. the arc panel that the inner wall of first shell is equipped with can increase the thickness of shell, increase body strength and toughness, and And due to offering cavity on arc panel, the overall weight of valve body can reduce, save the cost, and the company of being arranged in first shell The air channel of cavity is passed through, convenient for the connection of gas；

2. the stiffening plate that arc panel is equipped with can enhance the intensity of arc panel, and one end of stiffening plate is fixedly connected on Necking down plate reinforces its connection with shell；

3. bearing plate is installed with the fixed plate that side is fixedly connected on first shell inner wall far from one end of necking down plate, it is located at One end of the stiffening plate of arc panel two sides is fixedly connected on bearing plate；
