Description
Technical field
The utility model relates to a kind of hydraulic control one-way valves.
Background technique
Traditional hydraulic control one-way valve, the small head of valve rod are cooperated by M8 sinistral external thread and valve pocket levogyrate inner thread, mesh
Be that valve rod, reset spring, valve seat, big valve core, small valve core, spring, valve pocket are connected into a whole set of cartridge valve core assembly, it is convenient
In-site installation, disassembly.The core assembly of the method composition is still very convenient when dismantling component on mounted product, but
It is just more troublesome installing core assembly into valve body.The reason is that reset spring has certain initial thrust for valve rod to the left
It pushes away, part valve rod right end M8 sinistral external thread is caused tightly to fit together with valve pocket levogyrate inner thread.Due to valve pocket external screw thread with
Valve body internal screw thread is threadedly engaged for dextrorotation, and precession during installation must a little withstand Xiang Zuoxuan on the flat recess of valve rod left end with tool
One circle.It is repeated multiple times a whole set of core assembly to be packed into part valve body, it is time-consuming and laborious.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of core assembly spinning in and out very smoothly hydraulic control lists
To valve.
To solve the above problems, the technical solution adopted in the utility model includes: valve body, is mounted on the intracorporal valve of the valve
Core assembly, the valve body one end jointing, the core assembly include valve pocket, valve seat, valve rod, and the valve rod stub end is set
It in valve seat, the valve rod and connects and is equipped with the first spring between valve seat, big valve core, the small valve of cooperation are arranged on the valve rod
Core, the big valve core cover with valve seat in, between the small valve core and valve seat be equipped with second spring, it is characterised in that: the valve
Jump-ring slot is arranged in the small head end of bar, and the valve pocket bottom is equipped with interior circular hole, and the small head end of the valve rod stretches out the interior of the valve pocket
Circular hole, and be fixed by being clamped circlip in its jump-ring slot, and the valve pocket bottom is blocked by screw plug, the spiral shell
Stifled end is equipped with cavity.
The hydraulic control one-way valve, it is characterised in that: the screw plug rear end is equipped with interior hexagonal plum blossom hole.
The hydraulic control one-way valve, it is characterised in that: the screw plug is equipped with retaining ring, sealing ring.
The hydraulic control one-way valve advantage of the utility model is as follows: the small head original M8 sinistral external thread of valve rod being removed and is changed to Φ 8
Outer circle simultaneously opens a jump-ring slot, and the M8 levogyrate inner thread of valve pocket is removed, and is directly processed into circular hole and the small head of valve rod in a Φ 8
8 outer circle clearance fit of Φ.It is caught on the jump-ring slot of valve rod after each part closed assembly is good with the outer circlip of Φ 8, then screws in screw plug composition the whole series
Core assembly.This improved core assembly spinning in and out is very smooth, avoids the defective mounting of above-mentioned original image core assembly,
It greatly improves work task efficiency and reduces the labor intensity of worker.
The utility model is described further with reference to the accompanying drawings of the specification.
Detailed description of the invention
Fig. 1 is the cross-sectional view of the utility model hydraulic control one-way valve；
Fig. 2 is the cross-sectional view of the utility model core assembly figure；
Fig. 3 is the partial enlarged view that Fig. 2 is.
Specific embodiment
