For some scenarios where double-workstation grouting operations or simultaneous grouting operations of two slurries need to be realized simultaneously, two high-pressure grouting machines are required to work together, which will increase cost investment and reduce engineering benefits.

[0004] Although there are many types of inlet and outlet devices for grouting heads in the prior art, there is still the possibility of further innovation, and the present application is designed based on this. Summary of the invention

[0005] The purpose of the present invention is to design an inlet and outlet device for a hydraulically driven grouting machine, which can utilize a valve core assembly to perform reciprocating motion inside a flat square valve sleeve, thereby placing the entire inlet and outlet parts in a cross-conduction or closed state, thereby achieving a state where the entire inlet and outlet equipment is in a conducting or closed state.

[0040] like Figure 1 to Figure 8 As shown, the inlet and outlet equipment for the hydraulic push grouting machine can use the valve core assembly to reciprocate inside the flat square valve sleeve, so that the entire inlet and outlet parts are in a cross-conduction or closed state, thereby achieving the entire inlet and outlet equipment in a conduction or closed state, including the tee 5 and the inlet and outlet parts connected at both ends of the tee 5;

[0041] The inlet part includes a flat square valve sleeve 2 and a valve core assembly arranged in the flat square valve sleeve 2, and the two ends of the flat square valve sleeve 2 are respectively connected to the inlet joint 1 and the three-way interface 3;

[0042] The outlet component includes a flat square valve sleeve 2 and a valve core assembly arranged in the flat square valve sleeve 2, and the two ends of the flat square valve sleeve 2 are respectively connected to the outlet joint 6 and the three-way interface 3;

[0043] The interior of the flat square valve sleeve 2 is divided into two parts by the chassis 11. The inner wall of the flat square valve sleeve 2 located on the valve core assembly side is contracted to form an inner ring layer 12. A center hole 9 and a slurry hole 10 are provided on the chassis 11 along the thickness direction of the chassis 11, and the slurry hole 10 is penetrated on the valve core assembly side along the axial direction of the inner ring layer 12. Under the action of force, the valve core assembly reciprocates in the space on the valve core assembly placement side of the flat square valve sleeve 2.

[0044] As a preferred arrangement, the inlet and outlet equipment is mainly composed of a tee 5, an inlet part and an outlet part;

[0045] The inlet part is mainly composed of an inlet joint 1, a flat square valve sleeve 2, a valve core assembly and a three-way interface 3. The inlet joint 1, the flat square valve sleeve 2 and the three-way interface 3 can form an activity space, and the valve core assembly can be installed in the activity space and reciprocate in the activity space under the action of force;

[0046] The outlet part is mainly composed of an outlet connector 6, a flat square valve sleeve 2, a valve core assembly and a three-way interface 3, wherein the outlet connector 6 and the three-way interface 3 are respectively connected to the two ends of the flat square valve sleeve 2, and the outlet connector 6 is connected to the side where the valve core assembly is not provided, and the outlet connector 6, the flat square valve sleeve 2 and the three-way interface 3 can form an activity space, and the valve core assembly can reciprocate in the activity space under the action of force;

[0047] The tee 5 is connected to the tee interface 3 of the inlet and outlet parts respectively;

[0048] The flat square valve sleeve 2 serves as the main body of the activity space, and its interior is divided into two parts (referred to as the valve core assembly installation side and the non-valve core assembly installation side) by a formed chassis 11. The interior of the flat square valve sleeve 2 on the valve core assembly installation side thickens toward the center of the flat square valve sleeve 2 to form an inner ring layer 12. The height (also called depth) of the inner ring layer 12 is lower than the overall height of the valve core assembly installation side. A center hole 9 and a slurry hole 10 are provided on the chassis 11 along the thickness direction of the chassis 11 (i.e., the axial direction of the flat square valve sleeve 2). Preferably, the slurry hole 10 is evenly arranged on the outside of the center hole 9, and the slurry hole 10 is penetrated on the valve core assembly side along the axial direction of the inner ring layer 12 (i.e., a through groove (slurry hole wall 13) is formed in the height direction of the inner ring layer 12).

[0049] When in use, the inlet and outlet equipment is connected to an existing high-pressure grouting machine (that is, the existing high-pressure grouting machine can be replaced with the inlet and outlet equipment as a component of the inlet and outlet) or a high-pressure grouting machine independently developed by the applicant. The inlet joint 1 of the inlet part can be connected to the slurry inlet pipe, and the outlet joint 6 can be connected to the slurry outlet pipe. Under the action of high pressure (the pressure equipment provides pressure through the last channel of the tee 5), the valve core assembly will reciprocate in the flat square valve sleeve 2. At the beginning, since the valve core assemblies are all pressed against the same side, assuming that the movement of the valve core assembly on the inlet side is taken as a reference, when the valve core assembly on the inlet side moves in the direction of the tee, the valve core assembly on the outlet side does not move. At this time, the slurry in the slurry inlet pipe enters the inlet part, and the slurry on the inlet side It will run to the outlet side through the space formed by the valve core assembly and the flat square valve sleeve 2 via the tee 5; then the direction of the force is reversed, and the valve core assembly on the inlet side moves in the opposite direction under its own action to block the inlet on the inlet side. At this time, the valve core assembly on the outlet side will run to the outlet joint 6 side under the action of pressure, and the valve core assembly on the outlet side will form a flow channel with the flat square valve sleeve 2, and the slurry on the inlet side will be pressurized and flow out of the outlet through the flow channel and flow into the outlet pipe connected to the outlet; then the pressure is reversed again, at this time the channel on the inlet side is opened, and the valve core assembly on the outlet side will be reset due to its own setting reasons and block the outlet side, and this process is repeated to achieve the purpose of slurry inlet and outlet.
