Embodiment
The present invention includes valve seat 10, flap 09a, diaphragm 09, valve gap 07, valve rod 15 and actuator, actuator comprises two kinds of executive modes: 1, pneumatic executive mode; 2, manual executive mode, carries out moving up and down of flap and diaphragm by actuator, realizes closing of 09 pair of valve seat import and export of diaphragm.Valve seat 10 sealing surfaces and valve seat outlet level of subsistence, at same plane, also can flow out from outlet smoothly even if diaphragm 09 is closed media fluid, also can not be detained liquid (Fig. 1, Fig. 2); Diaphragm 09 and flap 09a are molded as a whole with the heterogeneity of bi-material, the gap between two different parts is eliminated completely, can not produce and be detained liquid betwixt, realizes nothing delay liquid (Fig. 1, Fig. 2) between diaphragm 09 and flap 09a; Film for sealing sheet 09 between valve gap 07 and valve seat 10 substitutes, as a whole with valve clack sealing ring, between normal conditions bottom flange 07 and valve seat 10, at least need clip seal ring and O type circle to seal, even if sealing can not be gapped the filling up (Fig. 3) of valve gap 07 and valve seat 10; Valve seat 07 is provided with aperture R1, this aperture one end communicates with the chamber R2 that diaphragm 09 and valve gap 07 form, one end communicates with external environment atmosphere, aperture R1 discharges because movement and deformation changes the air pressure of chamber R2 diaphragm 07 to chamber R2 air pressure like this, reach the balance (Fig. 1, Fig. 2) of chamber R2 pressure and ambient pressure environment.
Pneumatic mode refers to and comprises valve gap 07, cylinder head 03, spring 06, spring 05, valve 12, transparent cover 01, indicates button 02 and seal ring 04,13,14 forms, valve gap with cylinder head with being threaded;
Manual mode refers to and comprises that handwheel 17, drive link 16, valve gap 07, collar 18 form, drive link 16 is threaded with valve gap 07 use, drive link is connected with the T-shaped chute of valve rod 15 use, two kinds of executive modes are common general a kind of diaphragm 07, a kind of valve seat 10, a kind of flap 09a, a kind of specification clip all, realize mechanism simplifying, part standard, manufacture cost reduces.This device being connected between valve gap 07 and valve seat adopts clip connected 08, and this is easy to connect reliable, and convenient disassembly, cleans (Fig. 1, Fig. 2) easy to maintenance.This device is except single actuator, can also realize the threeway valve seat of two actuators, valve seat two ends are connected with identical actuator respectively, closing of the same actuating mechanism controls inlet seal separately of Bing Youdan actuator, and the outlet of one of public centre, the two ends mouth of pipe can pass into different media fluids like this, and the switch being sealed by actuating mechanism controls respectively, there is same outlet to mix and flow out, realize liquid and mix (Fig. 4).
Film for sealing sheet 09 between valve gap 07 and valve seat 10 substitutes, itself and valve clack sealing ring design as a whole, not only reach all sealing functions, and the fit up gap between valve gap 07 and valve seat 10 is filled full, not having media fluid to immerse gap may, can not produce the possibility of bacteria breed, realize pollution-free.
Wherein pneumatic mode execution principle is valve 12 inflations, spring 06 pressurized overcomes spring 05 tension force and moves down, pneumatic valve rod 15 is integral type structure with spring 05, move down together, and driving the flap 09a being attached thereto to move down together with diaphragm 09, valve seat 10 sealings are opened, otherwise, when valve 12 is died, diaphragm 09 moves under the tension force of spring and closes (Fig. 1).
Manual transmission mode principle is that handwheel 17 is fixed by screws on drive link 16, drive link 16 is threaded with valve gap 07 use, 17 drive links 16 of rotation hand wheel rotate together and move up and down with respect to valve gap 07, drive link 16 is connected by a T-shaped groove with valve rod 15, and move up and down together, drive the diaphragm 09 and the flap 09a that are attached thereto to move up and down simultaneously, realize the Kai Heguan (Fig. 2) of valve base sealing.
Threeway valve seat aseptic diaphragm valve, its valve seat is made as three mouths of pipe, two ends are connected with identical actuator respectively, closing of the same actuating mechanism controls inlet seal separately of Bing Youdan actuator, and the outlet of one of public centre, the two ends mouth of pipe can pass into different media fluids like this, and the switch being sealed by actuating mechanism controls respectively, there is same outlet to mix and flow out, realize liquid and mix.
