Description
Technical field
The utility model is related to a kind of special joint component, is particularly used for the anti-test product for pushing away actuator 1FA14012 of B737
A kind of special joint component of overall performance.
Background technique
Since check valve connector exterior is without fixed thread, generally test method is to remove unidirectional valve union in the industry, will be certainly
The test splice of system is fixed on flow control valve and tests product.Existing defects are tested in this way, because of one-way valve
Leakproofness between connector and flow control valve cannot be reflected by test, be easy to cause product quality guarantee.Devise dedicated connect
After head, integrally product can be tested for the property, the performance of product can be not only gone out with integrated testability, can also tested out unidirectional
Leakproofness between valve union and flow control valve, and the quality of unidirectional valve union can also be directly tested out, not only save
The time has been saved, the repair quality of product is also improved.Dedicated test splice, such cost can also be equally bought from external producer
It is just very high, and the connection between the special joint and testing stand of import is also very complicated.
Summary of the invention
A kind of special joint component is provided the purpose of the utility model is to overcome the above-mentioned insufficient of the prior art, effectively
Increase the stability of test, while saving maintenance cost, improve the quality of product repairing.
The technical solution of the utility model is: being circular connector, the diameter of connector outer wall from top to bottom including cross section
Be sequentially increased to form the first connector, the second connector, third connector, the first connector, the second connector, third connector the center of circle same
On straight line；First connector outer wall is equipped with the threaded portion for the piping connection with testing stand, and the second inner nosepiece wall is equipped with sealing
Slot is evenly distributed with multiple card slots for stationary balls in third inner nosepiece wall, is cased with lining at corresponding card slot outside third connector
Set, the radius of third inner nosepiece wall are R, and the vertical range of center line to the steel ball center line of third connector is L, R < L；Bushing
Height be greater than card slot top to third connector bottom end distance.
The internal diameter of the seal groove is 14mm, width 2mm.
The utility model has the beneficial effects that: small in size, structure is simple, easy to use；Reduce maintenance cost；It avoids
Multiple disassembly, improves production efficiency；Any part on product to be detected can not had to remove and treat testing product progress
Whole performance test.
Detailed description of the invention

Specific embodiment
In Fig. 1, the utility model includes that cross section is circular connector 1, and the diameter of 1 outer wall of connector from top to bottom successively increases
It is big to form the first connector 1-1, the second connector 1-2, third connector 1-3.First connector 1-1, the second connector 1-2, third connector 1-3
The center of circle on the same line.First connector 1-1 is the cone mouth screw thread of civil aviaton's standard, internal diameter 8mm, outer diameter 15.8mm.The
One connector 1-1 outer wall is equipped with the threaded portion 4 for the piping connection with testing stand.Second connector 1-2 inner wall is equipped with seal groove
5, the internal diameter of seal groove 5 is 14mm, width 2mm.Second connector 1-2 external diametrical extent is 18mm~25mm, internal diameter 10.9mm.
Third connector 1-3 internal diameter is 16mm, and outer diameter is greater than 26mm, and steel ball anti-pass power will not damage check valve when can guarantee 35MPa in this way
Connector.4 card slots for stationary balls 3, corresponding card slot outside third connector 1-3 are evenly distributed on third connector 1-3 inner wall
Place is cased with bushing 2.The radius of third connector 1-3 inner wall is R, the center line of third connector 1-3 to 3 center line of steel ball it is vertical away from
From for L, R < L.The height of bushing 2 is greater than card slot top to the distance of the bottom end third connector 1-3.The utility model is small in size, knot
Structure is simple, easy to use；Reduce maintenance cost；Multiple disassembly is avoided, production efficiency is improved.It can not have to remove to be checked
Any part surveyed on product treats testing product and carries out whole performance test.
In Fig. 2, the utility model is set on unidirectional valve union 7.4 steel balls 3 are placed in the 4 of third connector 1-3 inner wall
In a card slot.Bushing 2 is set on the outside of third connector 1-3, for fixing 4 steel balls 3.Unidirectional 7 inside of valve union be mounted with
Seal chamber is formed between seal groove 5 after sealing ring.First connector 1-1 outer wall is equipped with for connecting with the pipeline 6 of testing stand
The threaded portion 4 connect.The pipeline 6 of testing stand can be provided with testing stand to seal chamber hydraulic after connecting with the first connector 1-1.In liquid
Under the action of pressure, unidirectional valve union 7 and the utility model are tensed by 4 steel balls 3, can be big with 7 inside of leakproof one-way valve connector
The pressure of about 35MPa.The case where decrement of seal chamber does not have oil leak in the pressure of 35MPa.The utility model can be with
Test out the leakproofness between unidirectional valve union 7 and flow control valve 8.
