Abstract
The invention relates to a communicated labyrinth valve. A valve cover is arranged on a valve body, a valve base is arranged in the valve body, a pressure cover is arranged between the valve base and the valve cover, and a labyrinth assembly is arranged in the valve base and formed by a plurality of labyrinth sheets that are overlapped. The communicated labyrinth valve is characterized in that a plurality of communicated bent grooves are arranged on the labyrinth sheets; the valve body and the valve cover are mounted together by a nut; and a gasket is arranged between the pressure cover and the valve cover for sealing. Compared with the prior art, the invention has the advantages of: (1) markedly decreasing the runner blocking probability of the labyrinth and reducing the accident rate by about 60%; (2) guaranteeing safe and stable operation of the product, improving the efficiency and prolonging the maintenance period, and bringing distinct economical benefit; and (3) ensuring that the structure is simple, and the maintenance is convenient and quick.
Description
Technical field
The present invention relates to a kind of labyrinth valve, especially a kind of UNICOM formula labyrinth valve belongs to field of mechanical technique.
Background technique
High temperature, septum valve are widely used in many industries such as power station, metallurgy, petrochemical industry, and problems such as the cavitation of this class valve, noise and vibrations are insoluble problems always.The mazy type modulating valve is to design at this harsh operating mode specially, a kind of defective of labyrinth valve ubiquity in the present prior art, the labyrinth assembly (Fig. 3) that is exactly single runner is stopped up by medium or ducted foreign material easily, cause the forfeiture of labyrinth assembly step-down, decrease of noise functions or weaken, have a strong impact on the working life and the using effect of product.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of UNICOM formula labyrinth valve is provided, can reduce labyrinth flow-path and stop up probability, increase the service life.
According to technological scheme provided by the invention, a kind of UNICOM formula labyrinth valve adopts valve gap is installed on valve body, valve seat is installed in valve body, between valve seat and valve gap gland is set, is provided with the labyrinth assembly in valve seat, feature is: described labyrinth assembly is by some stacked the forming of labyrinth sheet; Described labyrinth sheet is provided with the bent groove of some mutual UNICOMs.
Connect fastening with nut between described valve body and the valve gap.
Between described gland and the valve gap gasket seal is set.
Compared with the prior art the present invention has the following advantages:
1, can stop up probability by minimizing labyrinth flow-path clearly, accident rate reduces about 60%;
2, can guarantee product safety, operation stably, raise the efficiency and prolong service cycle, bring remarkable economic efficiency;
3, simple in structure, easy to maintenance quick.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a labyrinth of the present invention chip architecture schematic representation.
Fig. 3 is the labyrinth modular construction schematic representation of prior art.
Embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As Fig. 1～shown in Figure 2: UNICOM's formula labyrinth valve comprises valve gap 1, gland 2, labyrinth assembly 3, valve seat 4, valve body 5, nut 6, pad 7, groove 8 etc.
Connect fastening with nut 6 between valve body 5 of the present invention and the valve gap 1.Valve seat 4 is installed in valve body 5, between valve seat 4 and valve gap 1, gland 2 is set, pad 7 sealings are set between described gland 2 and the valve gap 1; Be provided with labyrinth assembly 3 in valve seat 4, described labyrinth assembly 3 is by some stacked the forming of labyrinth sheet, and described labyrinth sheet is provided with the bent groove 8 of some mutual UNICOMs.
Working principle of the present invention: the bent groove 8 of many mutual UNICOMs is carved with on sheet surface, labyrinth, crooked groove 8 has increased the damping of fluid motion, play multistage hypotensive effect, made pressure drop be evenly distributed in each corner, thereby reached the purpose of effective control flow velocity; Increased redundant gateway, minimizing labyrinth flow-path that can be clearly stop up probability simultaneously mutually the labyrinth redundancy structure of UNICOM make medium or impurity be difficult to be blocked in the groove 8.This product structure is reasonable, and function admirable greatly reduces accident rate when keeping step-down, decrease of noise functions, prolonged the working life of product.
