Abstract
The utility model relates to a compact three-way reversing valve which comprises a cylinder, a valve body, a valve plate, a valve rod and sealing rings, wherein one end of the valve rod is vertically connected with one side of the valve plate. The three-way reversing valve is characterized in that the valve body consists of three cavities axially arranged along the valve rod, and valve bases are respectively arranged between the middle cavity and the adjacent cavities; the sealing rings are arranged on the valve bases and made of aero-specific rubber; a valve port is formed on one side of each cavity and is rectangular; the valve plate is positioned in the cavity in the middle; and the other end of the valve rod hermetically passes through one end of one cavity in a sliding manner and is connected with a cylinder piston rod connected with the end part of the cavity. The utility model is characterized by good sealing performance, long service life, less reversing time, and less occupied space.
Description
Technical field
The utility model relates to a kind of novel compact type three-way diverter valve, is mainly used in the high-temperature gas reversing mechanism of industry oven such as metallurgy, machinery, coloured, petrochemical industry.
Background technique
The selector valve of existing such use is general to use two to cut the valve realization soon, and all adopt circular valve port, valve quantity is many, and poor sealing performance is under same traffic requirement, its valve port height height, cause the cylinder stroke long, turn around time is long, and the selector valve volume is big, problems such as distortion is big during high temperature, and working life is short.
Summary of the invention
The purpose of this utility model provides a kind of compact type three-way diverter valve, and is big with the selector valve volume that solves existing such use, and distortion is big, and the cylinder stroke is long, and turn around time is long, the problem that working life is short.
The compact type three-way diverter valve that the utility model provides comprises cylinder, valve body, valve plate, valve rod and seal ring, one end of valve rod is vertically connected on a side of valve plate, it is characterized in that, described valve body is made up of three cavitys along the valve rod axially-aligned, respectively be provided with a valve seat between cavity in the middle and the adjacent cavity, be provided with seal ring on valve seat, seal ring adopts the aviation special (purpose) rubber to make; Side at each cavity is equipped with valve port, and valve port is a rectangular; Described valve plate is positioned at the middle part cavity, and the other end sealing slip of described valve rod passes an end of cavity and is connected with the cylinder piston rod that is connected this cavity end.
Slip surface between described valve rod and the cavity adopts copper sheathing to be connected.
The utlity model has following advantage:
(1) product service life is on average greater than 3,000,000 times, and this of domestic other existing like product performance is less than 1,000,000 times.
(2) the valve seal performance is good, and leakage rate is less than 0.05%, and domestic other these performance index of existing like product are 2%.
(3) the selector valve height reduces, and domestic other like product highly is 2 times of this product under same performance index condition.
(4) turn around time, because of the cylinder range ability shortens, be 50% of domestic like product turn around time less than 1 second.
Description of drawings
Fig. 1 is the general structure schematic representation of compact type three-way diverter valve described in the utility model.
Among the figure, 1 is cylinder, and 2 is valve rod, and 3 is support, and 4 is copper sheathing, and 5 is valve body, and 6 is valve plate, and 7 is valve port, and 8 is seal ring.
Embodiment
Referring to Fig. 1, the utility model comprises cylinder 1, valve body 5, valve plate 6, valve rod 2 and seal ring 8, valve body 5 is made up of three cavitys that are arranged in a linear, respectively be provided with a valve seat between cavity in the middle and the adjacent cavity, on valve seat, be provided with seal ring 8, side at each cavity is equipped with valve port 7, described valve plate 6 is positioned at the middle part cavity, one end of valve rod 2 is vertically connected on a side of valve plate 6, the other end of valve rod 2 slides along the length direction sealing of valve body 5 and passes an end of valve body 5, and be connected with the piston rod of the cylinder 1 that is connected valve end, being connected by support 3 between valve body 5 and the cylinder 1, described seal ring 8 adopts the aviation special (purpose) rubbers to make.
Seal sliding surface between described valve rod 2 and the valve body 5 adopts copper sheathing 4 to be connected.
Working principle of the present utility model is as follows:
The piston rod of cylinder 1 drives valve plate 6 and moves up and down valve port 7 conductings on middle part and top when valve plate 6 falls among Fig. 1.And valve plate 6 mentions when upper, the valve port mutual conduction of middle part and bottom, thus realized the conversion of path.The utility model is used in particular for the frequent alternately conversion and control to dibit two-way pipeline, when this application, adopt two the utility model, two valve ports of upper and lower part are in parallel respectively as suction port and air outlet, and two middle part valve port active chambers connect can realize above-mentioned alternately control.
