Abstract
The utility model relates to a combined valve, which comprises three cylinders and a valve body, and is characterized in that the valve body includes an upper cavity, a middle cavity and a lower cavity, partition plates for division are arranged in the middle of the middle cavity, an outlet is arranged at the uppermost layer, two outlets are arranged on a second layer, an outlet is arranged on the lowest layer, and two valve blocks arranged on guide rods of the left cylinder and the right cylinder are respectively mounted at the positions of passages between the second-layer cavity and the first-layer cavity and between the second-layer cavity and the third-layer cavity. The combined valve applied to the bottom of a suction drying machine changes a traditional structure with four valves at the bottom, realizes regeneration and absorption pressure maintaining functions between two absorption towers, and has the advantages of simple assembly and manufacturing, favor for large-scale production and transportation and convenience for use and maintenance.
Description
Technical field:
The utility model relates to a kind of combined valve.
Background technology
The machine of blotting is to belong to a kind of compressed air cleaning equipment, is combined by double tower, and adsorbents such as aluminium oxide or molecular sieve are housed in the tower, is used for absorbing the airborne moisture of compression.This equipment adopts the double tower wheel to change jobs, and absorption and regeneration overlap and carries out, and utilize the adsorptivity of adsorbent, reduce the moisture in the compressed air.The structure that four valves are adopted in the tradition bottom realizes regenerating between two adsorption towers, functions such as absorption pressurize.
The utility model content
In order to overcome above-mentioned defective, the purpose of this utility model provides a kind of combined valve.
To achieve these goals, the utility model adopts following technical scheme:
A kind of combined valve, it is made of 3 cylinders and a valve body, valve body divides upper, middle and lower three cavitys, there is dividing plate to separate in the middle of the middle cavity, the superiors are provided with outlet, the second layer two outlets are set, bottom one deck is provided with outlet, two valve blocks are arranged on the cylinder guide rod of the right and left, and two valve blocks are installed in the passage place of second layer cavity and ground floor and second layer cavity and the 3rd layer respectively.When the cylinder guide rod moved upward, the upper strata exported and is communicated with an outlet of the second layer, and when guide rod moved downward, the upper strata outlet cut off with an outlet of the second layer, but an outlet of the second layer is communicated with bottom one deck cavity at this moment.The cylinder guide rod of bottom one deck is when pulling back, and beneath cavity is communicated with muffler.Cylinder is all controlled by two-position-five-way solenoid valve.
The several interfaces of valve all adopt square flange, and seal form is the polytetrafluoroethylsealed sealed pad sealing of tongue and groove, and a, b, the square flange of c mouth are all logical, so interchangeability is strong between valve;
The cylinder guide rod adopts 304 stainless steel guide rods, and the linear sealing between Tetrafluoro spacer and stainless steel valve port is adopted in the sealing of each valve block;
Adopt combined valve, the making and the set-up time of blotting the machine pipeline shorten greatly, between connecting line has only from the adsorption tower to the combined valve about two pipelines, and these pipelines all can machine in advance.
Combined valve Ying Yu blots motor spindle, changes the structure that four valves are adopted in traditional bottom, realize regenerating between two adsorption towers, and the absorption pressure holding function, this valve has assembling and manufacturing is simple, helps large-scale production and transportation, and operation and maintenance is convenient.

The specific embodiment
Further specify below in conjunction with accompanying drawing:
Shown in Fig. 2～7, a kind of combined valve, it is made of 3 cylinders 10 and a valve body 11, three cavitys of 11 fens upper, middle and lowers of valve body, there is dividing plate 13 to separate in the middle of the middle cavity, the c mouth of the superiors is a compressed air inlet port, the a mouth of the second layer is connected with the A tower, and the b mouth is connected with the B tower, and the d mouth of bottom one deck is the silencer exhaust outlet, two valve blocks 12 are arranged on the cylinder guide rod of the right and left, when the cylinder guide rod moved upward, the c mouth can be communicated with a or b mouth, when guide rod moves downward, c mouth and a or b mouth cut off, but this moment a or the b mouth be communicated with bottom one deck cavity.The cylinder guide rod of bottom one deck is when pulling back, and beneath cavity is communicated with muffler.Cylinder is all controlled by two-position-five-way solenoid valve.
Combined valve is in the application of blotting on the machine
The machine work of blotting can be divided into following 6 duties, and Fig. 2-6 is seen in the cylinder action of each combinations of states valve valve
1, A tower absorption, the regeneration of B tower, the silencer valve leaves,
Compressed air enters the discharge of a mouth from the c mouth and enters the absorption of A tower, and B tower regeneration gas is entered by the b mouth, discharges from silencer interface d
2, A tower absorption, the pressurize of B tower, the silencer valve closes
Compressed air enters the discharge of a mouth from the c mouth and enters the absorption of A tower, and B tower regeneration gas is entered by the b mouth, but because silencer interface d is in closed condition, GuBTa enters packing state.
3, A, the B tower switches, and the silencer valve closes
Compressed air enters a mouth and the b mouth is discharged simultaneously from the c mouth, enters the A tower and the B tower adsorbs simultaneously
4, A tower regeneration, the absorption of B tower, the silencer valve leaves
Compressed air enters the discharge of b mouth from the c mouth and enters the absorption of B tower, and A tower regeneration gas is entered by a mouth, discharges from silencer interface d
5, A tower pressurize, the absorption of B tower, the silencer valve closes
Compressed air enters the discharge of b mouth from the c mouth and enters the absorption of B tower, and A tower regeneration gas is entered by a mouth, but because silencer interface d is in closed condition, GuBTa enters packing state.
6, A, the B tower switches, and the silencer door closes
Compressed air enters a mouth and the b mouth is discharged simultaneously from the c mouth, enters the A tower and the B tower adsorbs simultaneously
7, get back to the first step, the absorption of A tower, the regeneration of B tower, the silencer valve leaves above 6 states like this and circulates successively.
Be the example that combined valve is applied to the machine that blots more than, combined valve can be applicable to other many occasions.
