Problems solved by technology

[0003] The currently known check valves press the valve ball against the conical valve seat by spring force to realize the normally closed state of the valve port of the check valve. The flow medium flowing in from the reverse cut-off port will work with the spring force to press the valve ball more tightly against the valve seat, so the flow medium cannot flow in the reverse direction
[0004] In the automobile cooling system, the known check valve is used. On the one hand, this type of check valve is easy to enter impurities, and the spring is not sensitive enough to the fluid pressure; on the other hand, the temperature difference between different stages of the cooling fluid medium is large, resulting in the Or the rubber is aging or the return spring is damaged, which affects the use effect

Embodiment 1

[0035] refer to figure 1 As an embodiment of the present invention, the adjustable check valve includes a valve body 100 and a valve core 200 .

[0036] Among them, the valve body 100 includes a first valve assembly 101 and a second valve assembly 102, each of which forms a fluid chamber inside; the valve core 200, the valve core 200 includes a valve disc 201 and a swing assembly 202, and the swing assembly 202 drives the valve clack 201 Qihe.

[0037] Specifically, the valve body 100 is a flange-like pipe structure, which divides the first valve assembly 101 and the second valve assembly 102 , and the two are fixed by welding or integral casting to form the valve body 100 . Both ends of the valve body 100 are provided with standard internal threads for connecting with external components, a liquid chamber is formed inside it, and a valve flap 201 is provided in the middle of the fluid chamber.

[0038] The valve flap 201 includes a fixed piece 201a and a rotating piece 201b...

Embodiment 2

[0043] refer to figure 2 As an embodiment of the present invention, the adjustable check valve includes a valve body 100 and a valve core 200 . Among them, the valve body 100 includes a first valve assembly 101 and a second valve assembly 102, each of which forms a fluid chamber inside; the valve core 200, the valve core 200 includes a valve disc 201 and a swing assembly 202, and the swing assembly 202 drives the valve clack 201 Qihe. The adjustable check valve is different from Embodiment 1 in that: the adjustable check valve also includes an adjustment assembly 300, which is arranged on the rotating shaft 202a and can select different axial fixed positions on the rotating shaft 202a.

[0044] The adjustment assembly 300 is used to assist in adjusting the axial position of the vane 202b on the rotating shaft 202a, so that the distance between the vane 202b and the fluid input port can be adjusted, so as to adapt to different fluid intensities and increase the sensitivity of...

Embodiment 3

[0051] refer to figure 2 As an embodiment of the present invention, the adjustable check valve includes a valve body 100 and a valve core 200 . Among them, the valve body 100 includes a first valve assembly 101 and a second valve assembly 102, each of which forms a fluid chamber inside; the valve core 200, the valve core 200 includes a valve disc 201 and a swing assembly 202, and the swing assembly 202 drives the valve clack 201 Qihe. The difference between the adjustable check valve and the second embodiment is that the first valve assembly 101 and the second valve assembly 102 are connected by internal and external threads, and an intermediate cavity Z is formed inside the connecting part.

[0052] Specifically, both the first valve assembly 101 and the second valve assembly 102 are flange-like parts, and at the joint end where the first valve assembly 101 and the second valve assembly 102 are connected, they are provided with external threads; the corresponding second val...

Abstract

The invention relates to an adjustable check valve, an automobile engine cooling system and an automobile; the invention provides the check valve, and the check valve comprises a valve body in which fluid cavities are formed and a valve core, wherein the valve body comprises a first valve component and a second valve component; the valve core comprises a valve clack and a swing assembly; and the valve clack is driven by the swing assembly to be opened and closed. Moreover, the invention further provides the automobile engine cooling system provided with the check valve and the automobile. By employing the unique unidirectional control structure of the check valve, unidirectional control functions of positive turnon and reverse cutoff of rising liquid steam in a water outlet of a radiator can be effectively achieved; the check valve can be reliably applied to the engine cooling system, and therefore, the problem that temperature rise is slow when an engine runs at low temperature, and the like is solved; the power of the engine is obviously increased, oil consumption is reduced, the dynamic performance of the engine is improved, and the air warming effect is improved.

Description

technical field [0001] The present invention relates to a valve, in particular to a check valve. In addition, the present invention also relates to an automobile cooling system provided with a check valve, and an automobile having the automobile engine cooling system. Background technique [0002] The check valve is one of the important parts of the automobile cooling system. The purpose of installing the check valve in the cooling system is to prevent the reverse flow of the cooling fluid medium on various pipelines or equipment, which will affect the normal work. [0003] The currently known check valves press the valve ball against the conical valve seat by spring force to realize the normally closed state of the valve port of the check valve. However, the flowing medium flowing in from the interface of the reverse cut-off end will jointly press the valve ball against the valve seat more tightly with the force of the spring, so the flowing medium cannot flow in the rever...
