Embodiment 1

[0046] This embodiment provides an axial flow automatic control valve, such as figure 1 As shown, it includes: a valve body 1, a fixing member 4 and a driving structure, a fixing member 4 is fixedly arranged in the cavity of the valve body 1, and the fixing member 4 is provided with a stepped hole facing the side of the water inlet 2; the valve flap 9 can be slidably arranged In the stepped hole; an elastic member 8 is arranged in the stepped hole, one end of the elastic member 8 is fixed on the fixing member 4, and the other end is fixed on the valve flap 9; wherein, the elastic member 8 exerts elasticity towards the water inlet 2 on the valve flap 9 For the biasing force, the elastic member 8 may be a spring. The valve rod 7 is slidably passed through the fixing member 4, and the valve rod 7 is arranged coaxially with the stepped hole. Wherein, the driving structure includes a driver and a driving part, and the driver and the driving part are electrically connected. The dr...

Embodiment 2

[0062] This embodiment provides an axial-flow automatic control valve, which is different from the axial-flow automatic control valve provided in Embodiment 1 in that the driving part may be a telescopic rod, and the telescopic rod is connected to the valve rod 7 . That is to say, by driving the valve rod 7 to reciprocate by driving the telescopic rod to extend and retract by the driver, it is also possible to automatically drive the valve rod 7 to separate from the valve flap 9 or press the valve flap 9 against the valve seat 10 .

Abstract

The axial-flow type automatic control valve comprises a valve body, a fixing piece and a driving structure, the fixing piece is fixedly arranged in a cavity of the valve body, and a stepped hole facing one side of a water inlet is formed in the fixing piece; the valve clack is slidably arranged in the stepped hole; an elastic piece is arranged in the stepped hole, one end of the elastic piece is fixed to the fixing piece, and the other end of the elastic piece is fixed to the valve clack. The elastic part applies elastic bias pressure towards the water inlet to the valve clack. The valve rod is slidably arranged in the fixing piece in a penetrating mode, and the valve rod and the stepped hole are coaxially arranged. Wherein the driving structure comprises a driver and a driving part, and the driver is electrically connected with the driving part. The driver drives the driving part to drive the valve rod to be separated from the valve clack or enable the valve clack to abut against the valve seat, the valve rod is automatically driven to abut against the valve clack, and workers do not need to manually control the valve rod.

Description

technical field [0001] The invention relates to the technical field of valve bodies, in particular to an axial flow automatic control valve. Background technique [0002] Valves are pipeline accessories used to open and close pipelines, control the flow direction, and adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to its function, it can be divided into shut-off valve, check valve, regulating valve, etc. [0003] In the prior art, in order to actively control the closing of the check valve, the medium is prevented from pushing the valve flap from the water inlet to flow to the water outlet. The staff drives the threaded rod to move by turning the handwheel, and the threaded rod supports the valve disc to prevent the valve disc from being washed away by the medium, causing the medium to flow from the water inlet to the water outlet. [0004] However, in the prior art, to control the closing of the check valve, a staff m...
