Background
The inlet valve chamber of the diaphragm pump is connected with the screw rod, so that the problem of frequent fracture exists in the operation process, the safe and stable operation of the diaphragm pump is seriously influenced, casualty accidents are easily caused, and the normal organization of production is influenced. Research and analysis on multiple bolt fractures show that the bolt fractures are not all fractures together, but are mostly fractures at first by one corner; the longer the bonnet valve chamber is in use, the more severe the wear and the more frequent the breakage. The valve cover fastening bolt is broken mostly because the fastening bolt is influenced by shearing force and vibration of the valve cover in the vertical direction while being under the action of strong tensile force, so that mechanical fatigue is caused.
When the joint surface of the valve cover and the valve chamber can be in seamless close contact, and the acting force of the valve cover on the bolt changes due to pressure change in the inlet valve chamber, the acting force of the valve cover on the bolt also changes in a symmetrical balance mode along the stress point of the bolt, and the mechanical performance of the bolt is best exerted. However, when the two surfaces are used for a long time, corrosion and abrasion can be generated, and the joint surface is not seamless, the acting force of the valve cover on the bolt is not symmetrical and balanced any more, and the stress direction of the bolt is deviated due to uneven stress, so that the bolt is broken due to the fact that the bolt bears shear stress. It is therefore important to ensure that the valve chamber abutment surfaces can be seamlessly abutted.

The utility model aims to: aiming at the existing problems, the sealing component which is tightly attached to the sealing surface of the inlet valve chamber is arranged, the sealing component is connected to the valve cover, and the sealing surface is ensured to be tightly attached at any time by replacing the sealing component in time.
The technical scheme adopted by the utility model is as follows:
the utility model relates to a diaphragm pump inlet valve chamber valve cover, which comprises a valve cover closely attached and connected with an inlet valve chamber, and a sealing assembly arranged between the valve cover and the inlet valve chamber, wherein the sealing assembly is connected to the valve cover.
Preferably, the sealing assembly is provided with at least one fastening bolt hole, and the fastening bolt penetrates through the valve cover and enters the fastening bolt hole to fasten the valve cover and the sealing assembly.
Preferably, six screw thread holes are formed in the surface of the sealing component, and the inner hexagonal screw thread penetrates through the valve cover to enter the screw thread holes.
Preferably, the bonnet is fixed to the inlet valve chamber by eight link bolts.
Preferably, a groove is formed in the middle of the inner surface of the valve cover, one surface of the sealing component is embedded into the groove, and the other surface of the sealing component is attached to the sealing surface of the inlet valve chamber.
Preferably, the sealing assembly is formed by coaxially connecting two cylindrical bodies with different diameters, and the sealing assembly is embedded into the opening of the inlet valve chamber to seal the opening.
In summary, due to the adoption of the technical scheme, the utility model has the beneficial effects that:
1. the sealing assembly and the valve cover are connected through the bolts and can be detached, so that the sealing assembly is convenient to replace.
2. The timely replacement of the sealing assembly can ensure that the joint surface of the valve cover and the valve chamber can be seamlessly attached, the acting force of the valve cover on the bolt is symmetrically and symmetrically changed along the stress point of the bolt, and the bolt is not easy to break.
3. The sealing assembly can be attached to the inlet valve chamber and the valve cover, so that good sealing performance is ensured.
4. The utility model can ensure the acting force of the valve cover on the bolt to be balanced, prolong the service life of the bolt and avoid causing safety accidents.
