Abstract

A discharging pulsation compensation device of a diaphragm pump relates to a discharging pulsation compensation device applied to a three-cylinder single-action diaphragm pump. The utility model provides a processing is convenient, light in weight, low cost's diaphragm pump ejection of compact pulsation compensation arrangement. The utility model discloses a nitrogen package, its characterized in that: a transition flange is arranged at the lower end opening of the nitrogen bag, and a discharge tee is arranged at the lower end of the transition flange.

Description

Discharging pulsation compensation device of diaphragm pump

Technical Field

The utility model relates to a be applied to ejection of compact pulsation compensation arrangement of three jars single action diaphragm pumps.

Background

The discharge pulsation compensation device is positioned at the hydraulic end position of the diaphragm pump and mainly plays a role in pulsation buffering for slurry conveying, and the discharge pulsation compensation device consists of a nitrogen bag and a square discharge tee joint, and two ends of the discharge pulsation compensation device are connected with a discharge pipe and an outlet flange. The existing discharge pulsation compensation device is combined with a nitrogen bag through a long stud penetrating through a square discharge tee joint as shown in fig. 4. As the stud needs to cross the cross hole of the square discharging tee joint, the strength of the minimum wall thickness needs to be ensured, so that the design size of the square tee joint is very large, and the nitrogen shell has uneven cast wall thickness and poor casting manufacturability due to the square flange characteristics.

Disclosure of Invention

The utility model discloses just to above-mentioned problem, provide a processing is convenient, light in weight, low cost's diaphragm pump ejection of compact pulsation compensation arrangement.

In order to realize the above purpose of the utility model, the utility model discloses a following technical scheme, the utility model discloses a nitrogen package, its characterized in that: a transition flange is arranged at the lower end opening of the nitrogen bag, and a discharge tee is arranged at the lower end of the transition flange.

As a preferred scheme of the utility model, the transition flange is provided with a plug corresponding to the opening of the nitrogen bag; the transition flange is connected with the opening end face of the nitrogen bag through a first connecting bolt.

Further, a sealing ring is arranged between the plug and the opening of the nitrogen gas bag.

As another preferred scheme of the utility model, the discharge tee comprises a tee body with a connecting lug, and end flanges are welded at two ends of the tee body; the connecting lug is connected with the transition flange through a second connecting bolt.

As a third preferred embodiment of the present invention, a sealing gasket 10 is disposed between the transition flange 4 and the discharge tee 2.

The utility model has the advantages that: 1. the utility model discloses simple structure need not during the casting to consider with the shaping of tee bend coupling part, the volume has been add nitrogen gas cladding casing problem that casting manufacturability is not good.

2. The utility model discloses a engaging lug and transition flange are connected, have reduced three-way volume and weight, and processing is convenient, low cost.

3. The utility model discloses the assembly is easy, has very strong class operability at the user scene.

4. The utility model discloses increase the transition flange, can guarantee that the foundry goods wall thickness is even in the casting process, be favorable to improve equipment fixing precision and operation security.
