Abstract
The utility model provides a high-pressure butterfly valve which comprises a valve body, a valve channel and a shaft arranged in the valve body channel. The high-pressure butterfly valve is characterized in that a boss is arranged on the wall of the valve body channel and is matched with a valve plate arranged on the shaft. The high-pressure butterfly valve provided by the utility model has the beneficial effects that the sealing boss is arranged on the wall of the valve body channel and is matched with a sealing surface on the valve plate, thus, the requirement on use in a synthetic ammonia installation can be completely met, and moreover, the high-pressure butterfly valve is simple in structure, low in cost, and good in sealing effect.
Description
Technical field
The utility model belongs to a kind of valve body parts, relates to concretely a kind of for the synthesis of ammonia device synthetic gas fast shut-off high pressure butterfly valve.
Background technique
In chemical industry, the use of valve body is common a kind of equipment unit, and the heavy caliber on pipeline in the urea synthesis ammonia system, high pressure, the fast shut-off valve is the difficult problem that China's valve is made always, because high to the usage requirement of valve, domestic generally be difficult to make meet the requirements of valve, high pressure butterfly valve particularly.Therefore, external famous brand name is all selected in most chemical plant, but external valve price is high, has also increased the cost of enterprise.Therefore, in order to fill up a high blank of domestic immediate action valve usage requirement, be necessary to develop and be fit to own use and valve that meet usage requirement.
The model utility content
The purpose of this utility model just provides a kind of high pressure butterfly valve, satisfies to require high pressure in the chemical industry in the On Ammonia Plant, and heavy caliber, the usage requirement of fast shut-off valve, and butterfly valve structure of the present utility model is simple, good economy performance easy to make.
A kind of high pressure butterfly valve of the present utility model comprises valve body and valve channel, and is arranged on the axle in the valve channel, it is characterized in that: be provided with a boss at described valve channel wall, this boss matches with valve plate on being installed in axle.Match with valve plate by at the valve channel wall boss being set, the rotation by Control Shaft just can make valve plate contact with boss to reach sealing purpose.
Further, the similar triangle of described valve plate, its drift angle is provided with the hole that cooperates with axle and can rotates with axle, is provided with seal ring in addition two angle ends of valve plate, and the end face of seal ring is the inclination sealing surface and matches with raised head face on being arranged on valve channel.By two end faces at valve plate seal ring being set cooperates with boss on the conduit wall and can make sealing effect better.
Further, described seal ring is fixed in the end face of valve plate by pressure ring, and described pressure ring is fixed by screws on the end face of valve body.Utilize the detachability of screw, can change using seal ring of a specified duration or that sealing effect is poor, convenient, quick.
Further, described boss sealing surface also is set to the plane of inclination, and cooperatively interacts with the inclination sealing surface of seal ring on the valve plate.Utilize cooperatively interacting of sealing plane of inclination, can fit better sealing effect by sealing surface.
Beneficial effect
The beneficial effects of the utility model are to cooperate with the sealing surface that valve plate arranges by seal boss is set at the valve channel wall, can reach the usage requirement in synthetic ammonia installation fully, and simple in structure, cost is low, good sealing effect.
Description of drawings
Structural representation when Fig. 1 is valve open of the present utility model,
Fig. 2 is the structural representation that valve closing of the present utility model is.
Embodiment
As shown in Figure 1, the structural representation of high pressure butterfly valve of the present utility model when opening, valve body 1 is arranged, vias inner walls at valve body 1 is provided with boss 3, end face on the described boss 3 is the inclination sealing surface, be provided with the axle 2 that is subjected to pneumatic actuator control in valve body 1, at axle 2 valve plate 4 be installed, described valve plate 4 can be followed axle 2 rotations.Valve plate 4 similar isosceles triangles are arranged at drift angle porosely to cooperate with axle.
As shown in Figure 1, 2, at the two ends of valve plate seal ring 5 is installed, seal ring 5 is fixed on by pressure ring 7 on the concave surface of end face of valve plate, and pressure ring 7 is fixed on the valve plate by screw 8, and the plane of inclination of the boss of the setting on the inclination sealing surface 6 that arranges on the described seal ring 5 and the valve body 1 cooperates.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
