Background technique

In the pipeline of existing conveyance fluid medium, for realizing the control function, generally be provided with annexes such as multiple valve and filter, as block or connect impurity in the stop valve, filter medium of flowing medium in the pipeline filter, prevent the safety check of medium back flow etc.Its deficiency is: the cost height, installation, dismounting are keeped in repair very inconvenient, time-consuming taking a lot of work, action need professional workforce.

Summary of the invention

The purpose of this utility model provide a kind of have block or connect ducted flowing medium, filter medium and prevent the multiple function of medium back flow, loading and unloading, combination brake switch and proporting easy to maintenance.

For achieving the above object, the utility model adopts following technological scheme: multi-functional combination brake switch and proporting, has valve body, valve body has first, second, third runner that connects according to this, and first flow disposes the stop valve mechanism that opens and closes this runner, and second channel arrangement has filtrating equipment, the 3rd channel arrangement has check valve mechanism, the first, the 3rd runner is communicated with inflow port respectively, goes out head piece, and the second runner sidewall has opening, and this opening is sealed by lid.

Described stop valve mechanism comprises the break valve cover that is fixedly arranged on first flow sidewall opening place, active configuration in break valve cover and with break valve cover sealing by valve rod, and be configured in the first flow, be used to open and close this runner by flap, be connected a end by flap, connect operator by the other end of valve rod by valve rod.

Described filtrating equipment comprises the screen pack that vertical second cross section of fluid channel is provided with, and has the mesh of perforation on the screen pack.

Described screen pack has a plurality of, and each screen pack has the mesh in different apertures.

Described check valve mechanism comprise active configuration in the 3rd runner, be used to open and close the non-return flap of this runner, and be connected the elastic component between non-return flap and the valve body.

The multi-functional combination brake switch and proporting that the utility model provides, have following characteristics: (1) this valve has stop valve mechanism, filtrating equipment, check valve mechanism, possess simultaneously and block or connect ducted flowing medium, filter medium and prevent the multiple function of medium back flow, do not influence pipeline flow, simple in structure, loading and unloading, easy to maintenance, the practicability height, cost is low.(2) because the second runner sidewall has opening, open can remove behind the lid and filter the impurity that stays and change filtrating equipment, easy and simple to handle, need not the professional workforce.(3) when removal of contamination and replacing filtrating equipment, because the effect of check valve mechanism, the fluid of pipeline can not reflux, and avoids waste.

Embodiment

Referring to figs. 1 through Fig. 6, multi-functional combination brake switch and proporting has valve body 1, valve body 1 has first, second,

third runner

11,12,13 that connects according to this, the first, the 3rd runner is communicated with inflow port 14 respectively, goes out head piece 15, and liquid entering hole 14, liquid outlet 15 all have worm structure, is used for being connected with pipeline.

First flow 11 disposes the stop valve mechanism that opens and closes this runner, this stop valve mechanism break valve cover 21, by valve rod 22, by flap 23, Joystick 24 etc.Break valve cover 21 is fixedly arranged on first flow sidewall opening place and seals by seal ring 25, pass through the spiral active configuration in break valve cover 21 by valve rod 22, pass through

block

26,27 and seal ring 28 and break valve cover 21 sealings by valve rod 22, stretch in the first flow 11 and connect by the upper end of valve rod 22 connection Joystick 24, its lower end and end flap 23.Have partition wall 16 in first flow 11, partition wall 16 offers the flowing hole 17 of level, and this flowing hole 17 is positioned at by flap 23 belows.End valve rod 22 along break valve cover 21 elevating movements by Joystick 24 drivings, can make by flap 23 and open or close flowing hole 17, thereby the function of flowing medium in the pipeline is blocked or connected in realization.

Described spiral by valve rod 22, break valve cover 21 can adopt multi-head spiral, thereby the flap stroke is little when stop valve mechanism is opened and closed, and is short during keying, realizes opening soon, closing soon.

With reference to Fig. 3, Fig. 6, Fig. 7, vertical second runner 12 cross sections are provided with two

screen packs

31,32,

screen pack

31,32 is corrugated shape, and be distributed with on the screen pack 31 and be distributed with the less perforation mesh 321 in aperture on the bigger perforation mesh 311 in aperture, the screen pack 32, carry out classified filtering, under the prerequisite that does not influence normal flow rate, realize best filtering effect.Have opening 18 at second runner, 12 sidewalls, lid 33 is sealed in this opening and is fixed on the valve body 1 by screw 331.Can remove the impurity that filtration stays in second runner 12 after opening lid 33, and change

screen pack

31,32.

The 3rd runner 13 disposes check valve mechanism, and described check valve mechanism comprises non-return flap 41, guide rod 43, return spring 44, guide plate 45 etc.Non-return flap 41 active configuration connect passage port at the 3rd runner 13 and second runner 12, guide plate 45 sets firmly in the 3rd runner 13 near going out head piece 15 places, be distributed with the pod apertures 451 of perforation on the guide plate 45, return spring 44 is connected non-return flap 41 and guide plate 45, and non-return flap 41 is connected an end of guide rod 43, the center hole of guide plate 45 is passed in the other end activity of guide rod 43.When stop valve mechanism closed, non-return flap 41 was under the effect of return spring 44, and the connection mouth sealing with the 3rd runner 13 and second runner 12 makes valve be in closed state, prevents ducted fluid reflux; When the stop valve mechanism opening, hydrodynamic pressure overcomes the elastic force of coordination spring 44, passes non-return flap 41, and the connection mouth of the 3rd runner 13 and second runner 12 is opened, and whole valve is on state.

The multi-functional combination brake switch and proporting that the utility model provides, have following characteristics: (1) this valve has stop valve mechanism, filtrating equipment, check valve mechanism, possess simultaneously and block or connect ducted flowing medium, filter medium and prevent the multiple function of medium back flow, simple in structure, loading and unloading, easy to maintenance, the practicability height, cost is low.(2) because the second runner sidewall has opening, open can remove behind the lid and filter the impurity that stays and change filtrating equipment, easy and simple to handle, need not the professional workforce.(3) when removal of contamination and replacing filtrating equipment, because the effect of check valve mechanism, the fluid of pipeline can not reflux, and avoids waste.
