Description
Technical Field
The utility model belongs to the technical field of the compressor, concretely relates to mixed petroleum gas compressor head.
Background
The cylinder cover of the existing mixed petroleum gas compressor head is processed by casting, is of a shell structure, has low strength, and is easy to deform when colliding or bearing large pressure; in order to reliably connect the shell-shaped cylinder cover with the cylinder body, the key points for fixing the cylinder cover are more, so that the number of used bolts is large, the structure is complex, and the production cost is high; meanwhile, the piston in the cylinder body is inconvenient to overhaul and install.
In addition, an air valve assembly is arranged between the cylinder cover and the cylinder body, and the air valve assembly corresponds to an air inlet and an air outlet in the cylinder cover; the gas in the cylinder body enters and exits the cylinder cover through the gas valve assembly.
The cylinder cover structure of the shell is limited, the existing sealing gaskets are used for sealing between the cylinder cover and the air valve assembly and between the air valve assembly and the cylinder body, the problem of air leakage can occur after the sealing gaskets are used for a period of time, and the sealing effect is poor.
Disclosure of Invention
The utility model provides a simple structure, safe and reliable's mixed petroleum gas compressor head to above-mentioned problem.
In order to realize the above object of the utility model, the utility model discloses a following technical scheme, the utility model discloses a compressor head, the opening part of compressor head's cylinder block has set gradually pneumatic valve assembly and cylinder cover body, its characterized in that: the air cylinder cover body is of a block structure, and an air inlet hole and an air outlet hole are formed in the side of the air cylinder cover body; a through hole for communicating the air inlet hole and the air outlet hole is formed in the air cylinder cover body and matched with an air path of the air valve assembly; the outer circumference of the cylinder cover body and the air valve component is provided with a connecting hole, and the cylinder body, the air valve component and the cylinder cover body are fixed into a whole through a connecting bolt in the connecting hole.
As an optimized scheme of the utility model, pneumatic valve assembly both sides surface all is provided with the seal groove, is provided with O type sealing washer in the seal groove.
As another preferred scheme of the utility model, the open end of cylinder block is provided with the connecting block, be provided with on the connecting block with the screw hole that the connecting hole corresponds.
The utility model has the advantages that: 1. the cylinder cover body of the utility model is a block structure, compared with the existing casting structure, the strength is increased, and the safety of the machine head is more reliable; meanwhile, the connecting block is arranged at the top of the cylinder body and is more reliably connected with the cylinder cover body, and the thickness of the cylinder body is increased due to the structure of the connecting block, so that the structural strength of the cylinder body is improved.
2. The utility model discloses pneumatic valve subassembly and cylinder cover to and all adopt O type circle sealed between pneumatic valve subassembly and the cylinder body, make the sealed reliability of mixed petroleum gas compressor head promoted by a wide margin.
3. The cylinder cover body of the utility model is a block structure, so that the installation can be realized by arranging at least 3 bolts at the edge, and compared with the prior structure, the use number of the bolts is reduced, so that the structure of the machine head is simple, and the installation and the maintenance are more convenient; the problem of omission of the connecting bolt at the fixed position is not easy to occur.
