Novel three-way pipe

Abstract

The utility model provides a novel three-way pipe, and belongs to the technical field of pipe fittings. The three-way pipe solves the problem that when an existing three-way pipe is detached from other pipe fittings, a master control switch needs to be turned off, and therefore troubles are caused. The novel three-way pipe comprises a three-way main body with a water inlet and a water outlet, and non-return units which are connected with the three-way main body and play a non-return role are arranged in the water outlet of the three-way main body. And control units which are matched with the non-return units and enable the non-return units to start and close liquid conveying during disassembly are arranged at the water outlets of the three-way main body. The utility model has the advantage that the switch can be replaced without turning off the master control switch.

Description

Technical Field

[0001] The utility model belongs to the technical field of pipe fittings and relates to a novel three-way pipe. Background Art

[0002] As the name implies, a tee has three openings, that is, one inlet and two outlets; or two inlets and one outlet. It is a type of chemical pipe fittings. It has T-shaped and Y-shaped, equal-diameter pipe openings, and different-diameter pipe openings. It is used at the confluence of three identical or different pipelines. Its main function is to change the direction of the fluid. Tee pipes are generally used at the connection of pipe fittings, but in actual use, due to damage to the pipe fittings, they need to be disassembled and replaced. When disassembling, it is generally necessary to turn off the control switch to stop the input of liquid before disassembling. However, this method is relatively troublesome and does not meet the use requirements. Summary of the invention

[0005] In the above-mentioned new three-way pipe, the control unit is a guide sleeve arranged in the water outlet and slidingly matched with the water outlet, the inner end of the guide sleeve is provided with a contact plate connected to the guide sleeve and in contact with the valve stem, and a filter screen is provided at the outer end opening of the guide sleeve, a ring gasket connected to the guide sleeve is provided on the outer end surface, and a plurality of flow grooves arranged along its circumferential direction are provided on the contact plate.

[0006] In the above-mentioned novel three-way pipe, the abutment plate is provided with a backflow ring plate connected thereto and in a trumpet shape to reduce the backflow of magazines.

[0007] Compared with the prior art, the new three-way pipe has the following advantages:

[0008] 1. The tee body is located in the water outlet and is provided with a check unit connected to it and plays a check role. The check unit consists of a left ring frame, a right ring frame, a valve stem, a valve disc and a reset spring. The tee body is located at the water outlet and is provided with a control unit that cooperates with the check unit and enables the check unit to start closing the liquid delivery when disassembled.

[0012] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0013] like Figure 1 , Figure 2As shown, the novel three-way pipe comprises a three-way main body 1 with a water inlet and a water outlet. The three-way main body 1 is provided with a check unit connected to the water outlet and having a check function. The check unit is composed of a left ring frame 2, a right ring frame 3, a valve stem 4, a valve flap 5 and a reset spring 6. The left ring frame 2 and the right ring frame 3 are both arranged in the water outlet of the three-way main body 1 and connected thereto. The left ring frame 2 and the right ring frame 3 are provided with an axial hole for the valve stem 4 to pass axially. The two ends of the valve stem 4 are respectively The left ring frame 2 and the right ring frame 3 are extended outwards, and a plurality of flow holes 7 are arranged along the circumferential direction of the right ring frame 3 on the end surface. The valve flap 5 is arranged on the valve stem 4 and connected with it. The reset spring 6 is sleeved on the valve stem 4, and the two ends of the reset spring 6 are respectively in conflict with the valve flap 5 and the left ring frame 2. The valve stem 4 is in conflict with the right ring frame 3 through the reset spring 6, and the flow hole 7 on the right ring frame 3 is sealed through the valve flap 5. The three-way body 1 is located at the outlet. A control unit is provided which cooperates with the check unit and enables the check unit to start closing the liquid delivery when disassembled. The control unit is a guide sleeve 8 which is arranged in the water outlet space and slidably cooperates with it. The inner end of the guide sleeve 8 is provided with a contact plate 9 which is connected to it and contacts the valve stem 4, and a filter screen plate 10 is provided at the outer end opening of the guide sleeve 8. A ring gasket connected to it is provided on the outer end surface of the guide sleeve 8. The contact plate 9 is provided with a plurality of flow grooves 11 arranged along its circumferential direction, through which liquid can enter the guide sleeve 8. When the pipe fitting is connected, the pipe fitting contacts the guide sleeve 8 to move inward, so that the contact plate 9 in the guide sleeve 8 contacts the valve stem 4, and drives the valve disc 5 in the valve stem 4 to separate from the right ring frame 3, so that the check unit forms a normally open structure. When the pipe fitting is removed, the reset spring 6 resets the valve disc 5, thereby forming a seal so that the three-way pipe can cut off the liquid delivery without closing the main control valve.

[0014] As a preferred structure, the abutment plate 9 is provided with a backflow ring plate 12 which is connected thereto and is in a trumpet shape and reduces the backflow of magazines. The backflow ring plate 12 is located in the guide sleeve 8 .

[0015] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0016] Although the terminology such as tee body 1, left ring frame 2, right ring frame 3, valve stem 4, valve flap 5, return spring 6, flow hole 7, guide sleeve 8, contact plate 9, filter screen plate 10, flow slot 11, backflow ring plate 12 is used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
