Description
Technical field
The present invention relates to valve technology field, particularly relate to a kind of threaded check valve.
Background technology
Check valve refers to that the fluid flowing through in check valve can only flow to Way out from import, the stream in exit
The valve that body cannot reflux.Because of the characteristic of its anti-backflow, check valve is applied to various hydraulic tool and hydraulic pressure
In equipment.Check valve is divided into plate-type non-return valve and threaded check valve according to connected mode.Wherein screw thread is even
Connecing formula check valve two ends with external screw thread, Application comparison is extensive, and it can be screwed on valve block or oil cylinder with one end,
Other end and hard tube or hose connection；Or two ends are all attached with flexible pipe or hard tube.As it is shown in figure 5,
For the threaded check valve of one conventional in the market, by valve body 1, jointing 2, spool 3 and
Spring 4 forms, and spool is arranged on valve inner, and valve body one end is shaped with external screw thread, and the other end is shaped with female thread,
It is shaped with external screw thread for hexagonal, two ends in the middle of jointing to be threadably secured with valve body and link together, this
Check valve has the disadvantage in that
(1) check valve is threadably secured by two parts part and links together, and two parts part will be external
Circle and endoporus carry out Precision Machining, add process time, improve cost.
(2) the hexagonal part that jointing one end uses when being shaped with the external screw thread being connected with valve body and install,
Being shaped with the female thread being connected with jointing on valve body again, both coupling parts add entire length with outer
Footpath size, adds 2 hexagonal parts, causes whole check valve volume excessive, and weight is also big, at some
The occasion of spaces compact is difficult to application.
(3) poppet valve core that nonreturn valve core uses, poppet valve core is made up of independent targeting part and tapered portion, and two
Part has the requirement of axiality and roughness, be through cylindricalo grinding, and efficiency is low, cost is high；And because increase
Add independent targeting part, the most virtually add entire length.
Summary of the invention
It is an object of the invention to overcome the defect of prior art, it is provided that a kind of simple in construction, low cost tight
The threaded check valve of the type that gathers.
For above technical problem, the technical solution of the present invention is to provide a kind of has following structure
Threaded check valve, including body, inserts body, steel ball, spring base and spring, and described body upper end is
Hexagonal configuration, lower end is provided with the second external screw thread；Described body interior be provided with from the top down jack, pilot hole and
First through hole, described pilot hole sidewall is also uniformly provided with multiple semi-circular chute excessively；Described insertion body upper end
Being provided with the first external screw thread, lower end is provided with reducing diameter part and lead, and wherein reducing diameter part diameter is than body jack diameter
Little 0.6-1mm, described lead interference fit is arranged in body jack, and described body hexagonal upper surface is through riveting
Swaging becomes groove and bound edge, described rim section to be stuck in the gap inserting body reducing diameter part and body jack, will
Body is fixedly connected into entirety with inserting body；The internal portion of described insertion is additionally provided with the second runner hole and spring base
Hole, is provided with bottom described second runner hole on multiple second through hole, the plurality of second through hole and described body
Multiple semi-circular chute position one_to_one corresponding excessively；Described steel ball is slidably arranged in the pilot hole of body, and by
Spring is pressed on described body the first through hole；Described spring base one end is plugged on the spring base hole inserting body
In, the other end is socketed in spring inner ring, and when steel ball moves to compression spring direction, spring base can limit steel ball
Stroke；The diameter 0.1-0.3mm bigger than steel ball size of described valve body pilot hole.
Beneficial effects of the present invention is as follows:
The threaded check valve of one of the present invention is received limit by riveting after inserting body insertion valve body and is formed fixing
Connect, use steel ball as spool without grinding, and pilot hole 0.1-0.3mm bigger than steel ball, can be right
The guiding that the motion of steel ball has been carried out, volume compact, lightweight, low cost.
