Embodiment Construction

[0046] Please check Figure 1 to Figure 9 , a preferred embodiment of a hydraulically driven drain valve with double displacement. The hydraulically driven drain valve with double displacement includes a valve body 100, a starting assembly, a hydraulic drive device, a full row mechanism, and a half row mechanism and a limiter 200.

[0047] The valve body 100 is provided with a drain port 110 .

[0048] The actuating assembly can open or close the drain port 110 , which is movably mounted in the valve body 100 . In this embodiment, the starting assembly includes a starting lever 610 and a lifting arm 620, one end of the lifting arm 620 is directly or indirectly connected to the starting lever 610 through a connecting rod, etc., and the starting lever 610 is provided with a first hook 611 and a second hook 612.

[0049] The hydraulic drive device is connected to the valve body 100, and it includes a piston, which is connected to the starting assembly through transmission. In t...

Abstract

The invention discloses a hydraulic driving drain valve with double displacement. The hydraulic driving drain valve comprises a valve body, a starting assembly, a hydraulic driving device, a full-displacement mechanism, a semi-displacement mechanism and a limiting part. The valve body is provided with a drain port. The hydraulic driving device comprises a piston in transmission connection with the starting assembly; the limiting part moves between a first position and a second position. During semi-displacement, the limiting part is located on the first position, so that the moving route of the piston is a short route, the piston drives the starting assembly to open the drain port, and the semi-displacement mechanism is matched with the starting assembly to achieve semi-displacement; during full-displacement, the limiting part is located on the second position, so that the moving route of the piston is a long route, the piston moves to drive the starting assembly to open the drain port, and the full-displacement mechanism is matched with the starting assembly to achieve full displacement. The route of the piston is controlled by means of the position of the limiting part to achieve the purpose of double displacement, only one hydraulic driving device is needed, the structure is simple and reliable, and cost is low; meanwhile, the drain valve is similar to a common drain valve in size, and universality is high.

Description

technical field [0001] The invention relates to a hydraulically driven drain valve with double displacement. Background technique [0002] The existing hydraulically driven drainage valve structure uses two hydraulic cylinders to realize full drainage and half drainage, that is, two pistons are used to realize different drainage volumes of full row and half row, which makes the structure complex and takes up a large space. Poor compatibility. For example, the Chinese invention patent notification number is CN101395419B, and the patent name is the patent of "hydraulic drive device". Contents of the invention [0003] The invention provides a hydraulically driven drain valve with double displacement, which overcomes the existing disadvantages of the background technology. The technical solution adopted by the present invention to solve the technical problem is: a hydraulically driven drain valve with double displacement, which is characterized in that it includes: [0004...
