This standard specifies the main connection dimensions and use conditions of hydraulic quick-change connectors for transmitting hydraulic power from agricultural tractors to agricultural implements. This standard applies to quick-change connectors for hydraulic pipelines other than brake pipelines that comply with ISO5676:1983. These pipe connectors need to be frequently connected and disconnected in order to transmit hydraulic energy from the tractor to the implement.

1 Scope
GB/T5862-2U04/15675.1932
General hydraulic quick-change connectors for agricultural tractors and machines. It specifies the main standards and conditions for the quick-change connectors on agricultural machines that transmit power from agricultural tractors to agricultural machines.
This standard is suitable for hydraulic quick-change connectors that meet the requirements of 1S0157:19% heat transfer to the hydraulic pipeline outside the power pipeline. This standard can be frequently connected to the components in order to transfer the power on the tractor to the machine. Moreover, 2 Normative referenced documents
The clauses in the following documents become vehicle standards through non-standard references. Any referenced documents with a long term of validity are not applicable to this standard (excluding the contents or revised versions of the revisions of the revisions). However, it is encouraged to reach an agreement based on this standard to use the latest version of the relevant parts. Any non-standard referenced documents shall apply to this standard: 56:183 Agricultural tractor and trailer brake 1) 2111:937 Hydraulic transmission quick-change joints are subject to: Part: Only and requirements of IS7241-2:2330 Hydraulic transmission quick-change joints Part 2: Test method 3 Terms and definitions
The following terms and definitions apply to this standard. 3.1bzxZ.net
A quick-change connector (commercially known as a female quick-change connector) has only one hole that can be used to enclose the plug. 3.2
Male quick-change connector (commercially known as a male quick-change connector) The male quick-change connector is fully inserted and fixed in the original connector hole. 4 Technical requirements
4.1 Dimension requirements
The dimensions of the micro-change connector shall comply with the provisions of Figure 1. The size of the micro-change connector shall comply with the provisions of this specification: For connectors with a specification of 2: only the size in Figure 1: The length of the ear diameter shall not exceed 1mm. For connectors with a specification of 2, the length of the diameter shall not exceed 1mm. For connectors with a specification of 2, the length of the diameter shall not exceed 1mm. For connectors with a specification of 11397:197, the diameter and inner diameter of the connector and the inner diameter of the connector shall be specified in the specifications of the micro-change connector and ... The standard specifies the quick-change head material, Sichuan 4 standard or the specified joint is not GR/T58.2--254/1505575:1002. The whole project is non-ball collection. The ball can be small with 5 hydraulic quick-change joints. The size of the hydraulic quick-change joints is -, 7E2. The position and the dead part of the single busy must be concerned about the current 4,1. Note. When the core shape is non-shaped, it is used. The size is for. Medical country 4.2 The work should adopt the angle group containing.

4.2.1 Specification: 2.> Central connector, the filling standard is 45L/ea:n and the specification bridge is 2) type quick-dial connector. When the rated flow is 701./1mir, the average flow rate is not more than .4MP. The lake volume is 10241 2:1986, this standard requires that when the inner surface of the part is connected to the spherical core, the connection should be as described above. 4.2.2 The maximum positive force of the quick-release joint is 2MF (21>, the gasket head should be able to withstand a pressure of 70MI700uT).
4.2.3 The pressure of the male joint is -5MPa1eCbar), and the quick-release joint should be able to press continuously. The pressure of the 13.5-inch joint is 0.2: MP2.5ur, and the pressure of the 2-inch joint is 1CMP<!har), and the connection position is 200.
4.2.4 When the internal pressure of the quick-change connection is 17.17bar>, the current specification is 12.5 for the one that should exceed [. kV, the current specification should not exceed 2 steps of disassembly. The disassembly measurement should be 2! 21 is not allowed, 4.2.5 When the quick-change connection loses its standard element, the current specification is 1: type dial head, the speed pressure load should not exceed 7, 5L specification is 2; for the connector, the wave pressure wave is difficult to exceed 3m. The required force should not be greater than 3 specifications, and the value should not be greater than
2.2.7 If the case is not equipped with a stop device, the spring of the valve in the head should be used to prevent the door from closing under high speed and large volume. 5. The placement of quick-change joints on tractors
5.1 The rear-mounted pressure quick-change head
The male head of the quick-change joint should be as close as possible to the actual center axis of the tractor. 6.2 The front pressure quick-change joint || tt || is connected to the three 1 speed, the pressure quick-change joint of the A joint: is not in the case of the number of laying lines from the driver to estimate the location of the candle, then the virtual should be on the right side: if it is installed in the driver's creation, 5 is located at the lower horizontal position, from a pull point after the question is not right! m.
