A new height-adjustable, quick-replaceable silent drain valve structure

Abstract

The invention relates to a novel silent drain valve structure. The height of the novel silent drain valve structure can be freely adjusted according to mating height, and the novel silent drain valve structure is good in drain effect and can be fast replaced or maintained. The novel silent drain valve structure comprises a drain valve body, a drain base arranged below the drain valve body and used for being fixed to a toilet bowl water tank, and an overflow pipe connected with the drain base. A hollow drain connection base is arranged between the drain valve body and the drain base. A sealed air bag is arranged between the drain connection base and the drain base, connection nuts are arranged at the upper end and the lower end of the sealed air bag respectively, and the sealed air bag is connected with the drain connection base and the drain base through the two connection nuts. The drain connection base is provided with a guide sleeve with an opening, wherein the guide sleeve is arranged on the outer side of the circumference of the overflow pipe in a sleeved mode, can slide vertically along the overflow pipe and is fastened to the outer side of the overflow pipe by being locked by a butterfly nut.

Description

technical field [0001] The invention relates to a novel height-adjustable and quick-replaceable silent drain valve structure. Background technique [0002] In order to adapt to toilets of different heights, the drain valves currently installed in the toilet are all designed to have valve bodies with various height specifications, or the height of the drain valve can be changed by replacing drain bases of different heights. In this way, without knowing the height of the customer's toilet tank, it is often not known which size and specification of the drain valve height to choose for matching, and it is impossible to adjust any position according to actual needs, which brings heavy workload to matching and repairing. What's more serious is that it is necessary to develop a variety of drainage valve bodies or drainage bases with different heights, which greatly wastes production resources and labor costs; secondly, the current common use in the market to save development costs ...

Problems solved by technology

In this way, without knowing the height of the customer's toilet tank, it is often not known which size and specification of the drain valve height to choose for matching, and it is impossible to adjust any position according to actual needs, which brings heavy workload to matching and repairing. What's more serious is that it is necessary to develop a variety of drainage valve bodies or drainage bases with different heights, which greatly wastes production resources and labor costs; secondly, the current common use in the market to save development costs is to increase the drainage at a certain height. The drainage valve of the base, due to the increased size of the hollow cylinder on the base, makes the direction of the water flow intensified when the toilet is flushed and drained, thus forming a fast downwashing water column rushing to the bottom of the drainage channel, resulting in a strong recoil of the water flow, resulting in The flushing performance of the toilet is reduced, the flushing sound is louder and other bad phenomena, so now a large number of users are gradually abandoning the method of raising the base to increase the height of the drain valve
