Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings.

[0015] Such as figure 1 and 2 As shown, a submerged valve body test bench includes a pool 7 and a lifting plate 5, two vertically placed sliding rods 6 are set in the pool 7, a floor 8 is provided at the bottom of the pool 7, and the sliding rod 6 passes through the floor 8 and is fixedly connected with the pool 7 by screws. A sliding rod hole matching the sliding rod 6 is provided on the left and right sides of the lifting plate 5, and a copper sliding sleeve 4 is set on the sliding rod hole, which can reduce the friction resistance in the sliding process. The lifting plate 5 passes through the sliding rod hole sleeve On the two slide rods 6; a push rod 9 is set under the lifting plate, the lower end of the push rod 9 passes through the pool 7 and is connected to the cylinder 11, and the position where the push rod 9 passes through the pool 7 is covered with rubber ...

Abstract

The invention discloses an immersed valve body test bench comprising a water pool and a lifting board; left and right vertical slide rods are arranged in the water pool, and the lifting board is sleeved on the two slide rods through slide rods hole sleeves; a push rod is arranged below the lifting board; a bottom of the push rod is connected with a cylinder; a tested valve body is horizontally placed on the lifting board; a channel around the tested valve body is selected to be an observation channel, another channel is an air inlet channel connected with an air pipe, and the resting channels around the tested valve body are provided with sealing plugs; a main channel of the tested valve body is provided with a tooling piston matched in size with the main channel; the other end of the main channel of the tested valve body is provided with the sealing plug; positions, matched with the channels around the tested valve body, of the tooling piston are provided with holes connecting with the corresponding channels around the tested valve body, wherein the holes are mutually connected. The aerated device is immersed in the water, and bubbles can be observed if sand holes exist, thus fast determining whether product sealing property is qualified or not.

Description

technical field [0001] The invention relates to a test bench for a liquid processing device, in particular to a test bench for testing the sealing performance of a valve body assembly. Background technique [0002] The valve body of the liquid processing device is usually made of metal pouring, and there is often a through main channel in the middle of the valve body for the movement of the piston, and several other channels connected with the main channel are opened on both sides of the valve body , such as water inlet channels, water outlet channels, sewage channels, salt suction channels, etc. The sealing performance of the valve body is an important indicator to check whether the valve body is qualified. However, in the metal pouring process, there are often some tiny sand holes that affect the sealing performance of the valve body. These tiny sand holes are usually difficult to observe with the naked eye. arrive. Contents of the invention [0003] Technical problem ...
