Abstract

The utility model discloses a hydraulic three-way connection comprising a three-way body configured into one piece body with a liquid inlet and two liquid outlets by casting, through the liquid inlet and the two liquid outlets and at the middle part of the valve body being integratedly provided a liquid inlet chamber and two liquid outlet chamber which are communicated to one another, the bottom of the liquid inlet chamber being configured in a camber shape and together with the side walls of the two liquid outlet chambers configured in an arc shape for transition so as to enable the oil liquid to smoothly flow to the liquid outlet chambers through the shunting and guiding by the camber, which reduces pressure loss as oil liquid flows pass the three-way; wherein the ports of the two liquid outlet are provided with connect parts which are provided with a connecting thread and a sealing conical surface so as to achieve fast connection and good sealing performance.

Description

The hydraulic pressure tee union

Technical field

The utility model is about the hydraulic pressure tee union on a kind of hydraulic multitandem valve, with its structurally associated.

Background technique

Be connected to dual circuit by a hexagon tee union on the oil outlet of conventional hydraulic multi-way valve, to realize the logical oil of dual circuit, usually this hexagon tee union is to adopt casting earlier, the branch sap cavity that is communicated with this admission chamber again by secondary operations moulding one admission chamber and two in the joint piece, and respectively connect by welding at the port of admission chamber and two fens sap cavities and to establish a steel pipe and welded joint body to connect oil pipe, as shown in Figure 1, this tee union more complicated on manufacturing process, and following defective is arranged: the one, because this admission chamber is to adopt the secondary operations moulding with dividing sap cavity, cause the bottom of this admission chamber to form a depression position A, promptly make fluid enter the fittings body rear section and act on this depression position A, and form to interfere, and then make that to divide the pressure loss of sap cavity fluid excessive with the fluid that enters the branch sap cavity; Moreover, the port of this admission chamber and two fens sap cavities is respectively to connect by welding to establish a steel pipe and the welded joint body oil pipe that is connected again, the weld of this welded joint body easily produces the situation that the fluid seepage is caused in the crack in the use, because the above-mentioned deficiency of commonly using tee union, the design people has generation of the present utility model eventually through constantly studying.

The model utility content

Therefore, the purpose of this utility model is to provide that a kind of manufacturing process is simple, water conservancy diversion is smooth and easy and the hydraulic pressure tee union of easy disassembly.

For reaching above-mentioned purpose, technical solution of the present utility model is:

A kind of hydraulic pressure tee union, include a joint body, adopt casting, and one-body molded on this joint body have a liquid entering hole and two liquid separating ports, and admission chamber and the two fens sap cavities that communicates arranged to the joint body middle part is one-body molded through this liquid entering hole and this two liquid separating port, wherein, the bottom of this admission chamber is cambered surface.

The port of this liquid entering hole and this two liquid separating port respectively forms a junction.

This liquid separating port joint is provided with and connects spiral shell mosquito and sealing cone.

Adopt such scheme, the utlity model has following characteristics:

1, because admission chamber and two fens sap cavities of the utility model threeway are and this body by integral forming of tee union not need secondary operations to make that the tee union overall volume is less, reduce consumptive material.

2, the utility model is established the bottom of this admission chamber and is cambered surface, with the curved transition of the sidewall of this two fens sap cavities, and the pressure loss when reducing fluid through this tee union.

3, again the utility model tee union and oil pipe be connected that the connection spiral shell mosquito that processes on the port that is by two liquid separating ports and sealing cone realize, have to connect fast and the preferable characteristics of sealing.

Fig. 2 is the structure sectional view of the utility model hydraulic pressure tee union;

Fig. 3 is the side view of the utility model hydraulic pressure tee union.

Embodiment

As Fig. 2, shown in 3, structural representation for hydraulic pressure threeway of the present utility model, it comprises a threeway body 1, adopt casting, and one-body molded on this threeway body 1 liquid entering hole 11 and two liquid separating ports 12 are arranged, form admission chamber 13 through this liquid entering hole 11 to threeway body 1 middle part, form two fens sap cavities 14 by this two liquid separating port 12 to threeway body 1 middle part, and this admission chamber 13 is communicated with this two fens sap cavities 14, specifically, the cambered surface 15 that is protrusion is established in the bottom of this admission chamber 13 of the utility model, make the curved transition of sidewall of admission chamber 13 bottoms and this two fens sap cavities 14, and each one-body molded a junction 16 of port of this liquid entering hole 11 and this two liquid separating port 12 is processed with connection spiral shell mosquito 161 and sealing cone 162 on these joint 16 inwalls.

Said structure is adopted in the utility model threeway, because admission chamber and two fens sap cavities are and this body by integral forming of threeway, do not need secondary operations to make that the tee union overall volume is less, reduce consumptive material, and the bottom of this admission chamber is established and is cambered surface, fluid is entered in the branch sap cavity under the shunting guiding of cambered surface smoothly, thereby reduced the pressure loss when fluid is flowed through this threeway, moreover, connection spiral shell mosquito 161 that processes on the port of hydraulic pressure tee union of the present utility model by two liquid separating ports and sealing cone 162 are connected with oil pipe, have and connect fast and the preferable characteristics of sealing, overcome and commonly used threeway by being welded to connect a connecting head, causing seam crossing fluid leakage problems thus, is a technical innovation in fact.

Claims

1. hydraulic pressure tee union, include a threeway body, adopt casting, and one-body molded on this threeway body a liquid entering hole and two liquid separating ports are arranged, and be formed with admission chamber and the two fens sap cavities that communicates to threeway body middle part through this liquid entering hole and this two liquid separating port, it is characterized in that: the bottom of this admission chamber is established and is cambered surface.

2. hydraulic pressure tee union as claimed in claim 1 is characterized in that: each one-body molded a junction of the port of this two liquid separating port.
