Description

Technical Field

[0001] The utility model belongs to the technical field of engine thermal management, and relates to a multi-outlet constant temperature control valve for an engine. Background Technique

[0002] The normal operating temperature of the engine is 80°C - 90°C. An automobile is equipped with an engine thermal management module for controlling the coolant flow rate. When the engine temperature is on the high side, it can cool the engine to keep the engine working at a suitable temperature, that is, the engine works in a constant temperature state of 80°C - 90°C. Therefore, the engine thermal management module is also called the constant temperature control valve of the engine, and an electric actuator is provided on the constant temperature control valve.

[0003] In order to realize the coolant ratio adjustment of multiple pipelines, the constant temperature control valve in the existing automobile thermal management system is generally a multi-outlet constant temperature control valve. For example, a Chinese patent document publicly proposed a flow control valve and a cooling system [Publication No.: CN111692381A]. The flow control valve includes a housing, a driving mechanism (i.e., an actuator), and a valve body (i.e., a valve core). The housing is provided with a first row of outlets, a second row of outlets, and a third row of outlets at different positions. Outlet pipes are connected to the first row of outlets, the second row of outlets, and the third row of outlets.

[0004] The above-mentioned flow control valve is the multi-outlet constant temperature control valve of the engine. The existing constant temperature control valves are generally dedicated to one valve. When it is necessary to increase or decrease the outlets, it is often necessary to re-design the constant temperature control valve and re-open the mold for production, resulting in a large investment cost. Summary of the Utility Model

[0005] The purpose of the utility model is to address the above problems existing in the prior art, and propose a constant temperature control valve for an engine, which solves the technical problem of high investment cost when the existing constant temperature control valve needs to increase or decrease the outlets.

[0006] The purpose of the utility model can be achieved by the following technical solutions:

[0007] The multi-outlet constant temperature control valve for an engine includes a valve body. Several outlets are provided on the valve body. Removable outlet pipes are installed in the outlets. The outlet pipes are fixedly connected to the valve body by screws. Several threaded holes are provided on the valve body outside the outlets. It is characterized in that it further includes an outlet end cover for closing the outlets. A protruding positioning ring is provided on the back surface of the outlet end cover. The positioning ring can be inserted into the outlet to form radial positioning. A fixed retaining edge is provided on the outlet end cover outside the positioning ring. The fixed retaining edge can be abutted against the outer edge of the outlet. Several fixing holes corresponding to the threaded holes one by one are also provided on the fixed retaining edge.

[0008] When it is necessary to reduce the outlet, the outlet pipe is disassembled, and then the outlet end cover is closed to the outlet. The positioning ring is inserted into the outlet to form a radial positioning, and the fixing stop edge abuts against the outer edge of the outlet to form an axial positioning. The fixing holes correspond to the threaded holes one by one, and then the outlet end cover is fixed by screws. In this way, the outlet can be sealed well, thus reducing the outlet. When it is necessary to increase the outlet, just reinstall the outlet pipe after removing the outlet end cover. The manufacturing cost of the outlet end cover is much lower than that of redesigning and manufacturing a new constant temperature control valve. Therefore, the multi-outlet constant temperature control valve of this engine can reduce costs when increasing or decreasing the outlet.

[0009] In the multi-outlet constant temperature control valve of the engine described above, reinforcing rib plates are connected between the back surface of the outlet end cover and the inner side surface of the positioning ring. There are several reinforcing rib plates and they are arranged in sequence along the circumferential direction of the outlet end cover. The reinforcing rib plates can increase the structural strength of the outlet end cover, keep the structure of the outlet end cover stable during the use of the constant temperature control valve, and ensure the sealing effect of the outlet end cover on the outlet.

[0010] In the multi-outlet constant temperature control valve of the engine described above, a central convex ring is provided at the center of the back surface of the outlet end cover, and all the reinforcing rib plates are connected to the central convex ring. The setting of the central convex ring can further improve the structural strength of the outlet end cover, keep the structure of the outlet end cover stable during the use of the constant temperature control valve, and ensure the sealing effect of the outlet end cover on the outlet.

[0011] In the multi-outlet constant temperature control valve of the engine described above, a positioning block is provided on the valve body outside the outlet. The positioning block has two positioning planes facing opposite directions. On the back surface of the fixing stop edge, there are positioning convex parts corresponding to the positioning block. There are two positioning convex parts and they are arranged oppositely. The positioning block can be embedded between the two positioning convex parts, and the two positioning convex parts can respectively abut against the two positioning planes.

[0012] When the outlet end cover is closed to the outlet, the positioning ring is inserted into the outlet to form a radial positioning, the fixing stop edge abuts against the outer edge of the outlet to form an axial positioning. At the same time, the positioning block is embedded between the two positioning convex parts, and the two positioning convex parts respectively abut against the two positioning planes to form a circumferential positioning, so that the outlet end cover is stably fixed at the outlet.

[0013] In the multi-outlet constant temperature control valve of the engine described above, a protruding rib is provided at the outer edge of the back surface of the fixing stop edge, and both positioning convex parts are connected to the rib. This can increase the structural strength at the fixing stop edge, keep the structure of the fixing stop edge stable, and thus keep the structure of the outlet end cover stable during the use of the constant temperature control valve.

[0014] In the above-mentioned multi-way outlet thermostatic control valve of the engine, a protruding bump is provided on the outer side surface of the fixed stop edge, and the bump is close to the positioning convex portion. The bump provides a fulcrum when removing the outlet end cover, making it easy to remove the outlet end cover. In addition, since the bump is close to the positioning convex portion, the bump also has a marking function when installing the outlet end cover, making it easy to find the position of the positioning convex portion.

[0015] In the above-mentioned multi-way outlet thermostatic control valve of the engine, a sealing ring is provided on the positioning ring. When the positioning ring is inserted into the outlet, the sealing ring is located between the outer side surface of the positioning ring and the hole wall surface of the outlet to form a seal. The provision of the sealing ring can improve the sealing effect when the outlet end cover is fixed in the outlet, and prevent the coolant in the thermostatic control valve from leaking from the outlet.

[0016] Compared with the prior art, the utility model has the following advantages:

[0017] The multi-way outlet thermostatic control valve of the present engine is also provided with an outlet end cover, which can close the outlet, and the positioning ring of the outlet end cover is inserted into the outlet to form radial positioning, and the fixed stop edge of the outlet end cover is against the outer edge of the outlet to form axial positioning, and the screw passes through the fixing hole of the outlet end cover and is threadedly connected with the threaded hole of the valve body. The outlet end cover can be replaced with the outlet pipe, so as to increase or decrease the outlet of the thermostatic control valve. The manufacturing cost of the outlet end cover is much lower than that of redesigning and manufacturing a new thermostatic control valve. Therefore, the multi-way outlet thermostatic control valve of the present engine can reduce the cost when it is necessary to increase or decrease the outlet. BRIEF DESCRIPTION OF THE DRAWINGS
