Abstract
The invention provides an oil route block and plug connecting structure which is fine in sealing and can effectively prevent oil from leaking. The connecting structure comprises an oil route block and a plug, and a technological hole is formed in the oil route block. The connecting structure is characterized in that the plug comprises a head, a connecting portion a guide portion which are coaxially connected, the technological hole is a stepped hole, the connecting portion is connected with a large radial end of the stepped hole through a taper pipe in a threaded manner, a first sealing ring is embedded on the radial periphery of the guide portion, a second sealing ring is embedded between the lower end face of the connecting portion and the stepped face of the technological hole, and a third sealing ring is embedded between the lower end face of the head of the plug and the upper end face of the oil route block.
Description
Technical field
The present invention relates to electrohydraulic servo system technical field, particularly relate to the manifold block of hydraulic control oil work, be specially the linkage structure of manifold block and plug.
Background technique
The surface of manifold block is provided with mounting hole and auxiliary hole, the internal hydraulic pressure pipeline of mounting hole UNICOM manifold block, for connecting each plate type hydraulic valve; Auxiliary hole is for reducing the through hole that its difficulty of processing is arranged in the processing of manifold block, and after manifold block machine shaping, auxiliary hole need use plug plug to fill, sealing.Existing plug is threaded with auxiliary hole and is wound around raw meal belt and improves its sealability.But raw meal belt is under high-pressure situations, and sealability is poor, the joint easy oil leakage of manifold block and plug.
Summary of the invention
For the problems referred to above, the invention provides the linkage structure of manifold block and plug, its good seal performance, effectively can avoid leakage of oil.
Its technological scheme is such, the linkage structure of manifold block and plug, it comprises manifold block and plug, described manifold block is provided with auxiliary hole, it is characterized in that: described plug comprises the coaxial head connected, joint and guide portion, described auxiliary hole is step hole, described joint is connected by taper pipe thread with the larger end of the radial direction of described step hole, the outer radial periphery of described guide portion is embedded with seal ring one, seal ring two is embedded with between the lower end surface of described joint and the step surface of described auxiliary hole, seal ring three is embedded with between the lower end surface of the head of described plug and the upper-end surface of manifold block.
It is further characterized in that:
Described seal ring one is y-type seal ring, and along the opening direction of epipharynx and outer lip, described seal ring one is coated with the elastic skeleton of V-type;
The outer radial periphery of described seal ring one root is provided with the flange of 1 ~ 3 loop.
After adopting structure of the present invention, the joint of plug and the auxiliary hole of manifold block adopt taper pipe thread to be connected, the good airproof performance of connection; The outer radial periphery of guide portion is embedded with seal ring one, seal ring two is embedded with between the lower end surface of joint and the step surface of step hole, be embedded with seal ring three between the lower end surface of the head of plug and the upper-end surface of manifold block, the sealing that plug is connected with manifold block can be strengthened further; Seal ring one is y-type seal ring, along the opening direction of epipharynx and outer lip, seal ring one is coated with the elastic skeleton of V-type, and epipharynx, outer lip are fitted with step hole, guide portion respectively under the elastic acting force of V-type elastic skeleton, further strengthen the sealing that plug is connected with manifold block.In sum, structure of the present invention, its good seal performance, effectively can avoid leakage of oil.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation in the cross section of seal ring one of the present invention.
