Description

Technical Field

[0001] The utility model relates to the technical field of reciprocating pumps, in particular to a flow distribution valve group for a reciprocating pump. Background Art

[0002] A reciprocating pump is a conveying machine that directly provides energy to a liquid in the form of pressure energy through the reciprocating motion of a piston. According to the driving mode, reciprocating pumps are divided into two categories: motor-driven pumps (driven by electric motors) and direct-acting pumps (driven by steam, gas or liquid).

[0003] When a reciprocating pump is in use, a distribution valve is required. However, most of the distribution valves in reciprocating pumps are valve balls. Because the valve ball does not have a buffering function, the valve ball will be severely worn when it rolls in the outlet for a long time, resulting in poor sealing effect of the valve ball. Utility Model Content

When the valve ball seals the connecting pipe, the inertia of the spring drives the connecting plate to move, the connecting plate drives the connecting rod to move, and the connecting rod drives the valve ball to move. When the valve ball contacts the left arc of the connecting pipe, the connecting pipe can be sealed. When it is necessary to drain water through the connecting pipe, the pressure brought by the transmission rod mechanism drives the connecting plate to move to the left, the connecting plate drives the connecting rod to move, and the connecting rod drives the valve ball to move. When the valve ball moves out of the left arc of the connecting pipe, the connecting pipe can drain water normally. This method can limit the movement of the valve ball to prevent the valve ball from rolling in the water outlet, thereby reducing the friction of the valve ball in the water outlet.

[0006] The utility model discloses a distribution valve group for a reciprocating pump, wherein limit plates are provided on both sides of the bottom of the motor, a support frame is provided at the bottom of the limit plates, and the bottom of the support frame is in contact with the mounting seat. The utility model can fix the motor through the support frame and the limit plates, thereby avoiding shaking of the motor when in use, thereby causing unstable operation of the motor.

[0007] The utility model discloses a distribution valve group for a reciprocating pump, wherein fixing bolts are provided on both sides of the top of the support frame, and the bottom of the fixing bolts is threadedly connected to the mounting seat. The fixing bolts can facilitate installation and disassembly of the support frame, which is convenient for regular disassembly and maintenance of the motor.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] 1. When the valve ball seals the connecting pipe, the inertia of the spring drives the connecting plate to move, the connecting plate drives the connecting rod to move, and the connecting rod drives the valve ball to move. When the valve ball contacts the left arc of the connecting pipe, the connecting pipe can be sealed. When it is necessary to drain water through the connecting pipe, the pressure brought by the transmission rod mechanism drives the connecting plate to move left, the connecting plate drives the connecting rod to move, and the connecting rod drives the valve ball to move. When the valve ball moves out of the left arc of the connecting pipe, the connecting pipe can be drained normally. This method can limit the movement of the valve ball to prevent the valve ball from rolling in the water outlet, thereby reducing the friction of the valve ball in the water outlet.
