Contacted, and avoided direct contact with inboard wall of cylinder block by Wear-resistant plastic feed ring, so as to effectively extend the service life of piston.
The utility model, which may further be provided, to be additionally provided with the outer end face for the end cap by three one loopings of interface
If seal groove in the inner, gasket is embedded with the seal groove.
Using above-mentioned setting, by being embedded in same gasket toward seal groove, can realize to the close together of three interfaces
Envelope, it is simple in structure, it is easy to operate.
The utility model may further be provided and sealing device is additionally provided between the valve body and valve rod, and described is close
Seal apparatus includes gland, airtight and watertight padding, Packing spring and packing ring, and the gland, airtight and watertight padding, Packing spring and packing ring are coaxial
It is sleeved on valve rod, the lower end of packing ring is resisted against on valve interior wall, and upper end and the Packing spring lower end of packing ring abut against, and seals bullet
The upper end of spring is abutted against with airtight and watertight padding lower end, and the gland, which is spirally connected, to be fixed on valve body, and is formed to airtight and watertight padding upper end
Compress.
By setting sealing device, it can be achieved that sealing between valve body and valve rod, meanwhile, the airtight and watertight padding is in sealing bullet
Under the action of spring, sealing effect is more preferable.
The utility model may further be provided offers what is communicated with body cavity for the lower axial end portion of the valve body
Sewage draining exit, is equiped with chock plug on the sewage draining exit.Using the above structure, when there are during sediment, passing through in valve body and open plug
Head, can be discharged sediment in time by sewage draining exit.
