Problems solved by technology

[0004] 2. The driving fluid of the control part comes from the medium in the pipeline, the bypass pipe is easy to block, and the control cylinder is easy to deposit and scale, so it needs to be cleaned regularly
[0006] 4. When the return water pressure is lower than 0.1MPa, the closing of the small valve plate is not flexible or may even fail to close, and an auxiliary closing device needs to be added

Embodiment Construction

[0035] The present invention will be further described below in conjunction with accompanying drawing.

[0036] see figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 and Figure 6 , the valve body 1 is molded by metal casting, the valve plate 2 is assembled in the valve body 1, the valve stem 30 passes through the first shaft hole 36, the second shaft hole 37 of the valve body 1 and the third shaft hole 38 of the valve plate 2, The fourth shaft hole 39, the snap ring 28 is mounted on the end of the valve stem 30, and the stuffy cover 27 is fixed on the left end flange of the valve body 1 through the first screw 29, and simultaneously withstands the snap ring 28 to prevent the valve stem 30 from moving around. Moving, the taper pin 31 passes through the valve plate 2 and the valve stem 30 at the same time, making it a whole. The outer circle of the right end of the valve rod 30 is inserted into the shaft hole 4 of the crank arm 24 and fixed by the flat key 3 . The ...

Abstract

The invention discloses an integrated control water pump valve. One end of a valve rod (30) is fixedly connected with one end of a crank arm (24), a second check valve (20) is arranged on a piston (8), a cylinder seat slow-closure cavity (5) is formed in the bottom of a piston lower cavity (7), a slow-closure step (22) used together with the cylinder seat slow-closure cavity (5) is arranged on a piston rod (23), the lower end of the piston rod (23) and a guiding groove (25) in the other end of the crank arm (24) form a sliding hinge through a pin (34), an oil tank (15) is communicated with a piston upper cavity (9) through a second oil hole (16) in which a slow-closure control valve (17) is mounted, the oil tank (15) is communicated with the cylinder seat slow-closure cavity (5) through the slow-closure control valve (6), and a first check valve (13) is arranged between the piston upper cavity (9) and the oil tank (15). The integrated control water pump valve provided by the invention has the advantages of energy saving, environmental friendliness, wide adaptation and convenience in maintenance.

Description

technical field [0001] The invention relates to a valve, in particular to an integrated control water pump valve. Background technique [0002] The butterfly structure water pump control valve has the advantages of small size, light weight, small fluid resistance, driven by the pressure of the pipe network medium, no electricity, no oil, and is currently the most advanced water pump control valve in the market. It has been recognized by users , but such valves also have the following deficiencies: [0003] 1. The existing butterfly pump control valve generally adopts a double valve plate structure, the large valve plate is always suspended in the water, the fluid resistance is large, and the energy consumption is high, which does not conform to the national energy conservation and environmental protection policy. [0004] 2. The drive fluid of the control part comes from the medium in the pipeline, the bypass pipe is easy to block, and the control cylinder is easy to deposi...
