Description

Multi-path fluid pipeline alternately opens and closes valve

Technical field

The utility model is related to a kind of fluid-transporting tubing gate valve, especially a kind of multi-path fluid pipeline alternately opens and closes valve.

Background technology

In industries such as industry, agricultural and environmental protection, multi-path fluid conveyance conduit vertically stacks and horizontally-parallel arrangement is more normal See, and open simultaneously several sluice valves and close in addition several sluice valves it is also unrare.By taking water process filter membrane flushing work as an example, In the filter device of water process, after filter material filters a period of time, many filter openings can all block, and need to carry out filter material Positive and negative are rinsed, and need to be rinsed with filtered water when especially reverse side rinses.It will produce in this operating mode Four runners, raw water inlet, treated water outlet rinse water inlet, rinse water out.It is former when normal water processed (when crossing drainage) Water inlet and treated water outlet are opened, and water inlet and flushing water port closing are rinsed.When rinsing, valve opening and closed state On the contrary.Traditional technological process uses multiple solenoid valves.And valve is controlled using control system.To reach four pipelines Gate valve alternately opens and closes two-by-two, realizes water processed and flushing.But this mode valve quantity is more, pipeline complex fault rate is high, and control is also Individual hardware and software is needed, more resources are expended.

Utility model content

The purpose of the utility model is to overcome prior art deficiency, provide it is a kind of it is simple in structure, operation is fast and convenient, can To open simultaneously several fluid-transporting tubing gate valves, and the multi-path fluid for simultaneously closing off several pipeline gate valves alternately opens and closes valve.This The purpose of utility model realizes that multi-path fluid pipeline alternately opens and closes valve, including valve body, valve chamber, valve by following technical proposals Valve, valve rod, the flow channel entry point being connected with into fluid hose, the runner exit being connected with outlet, it is characterised in that：Several valve bodies are set to On same vertical plane or plane, the sluice gate in the single or several while valve body cavity opened is convexly equipped in valve chamber top or left part, individually Valve sluice gate in the several while valve body cavity closed is convexly equipped in valve chamber lower part or right part, is fixedly connected on valve rod among flap, and Each flap occupy in the middle part of each valve chamber, and valve rod passes through in the middle part of each valve body, upper part be equipped with screw thread and on most upper or left part valve body The nut seat socket being fixedly connected, valve stem tip are fixedly connected with handle or power, and gap is equipped between flap and valve body cavity wall and is made Flow channel for liquids, valve body touch position with valve rod and are equipped with sealing ring.

Several valve bodies are 2-20.

The handle is staight shank handle or disc handle.

The valve chamber can be cylindrical, can also be square cylindricality.

Described flap is round or rectangle.

Described several valve bodies can be separate several split type valve bodies, can also be designed to an integrated valve It is arranged in parallel in overlapping or left and right up and down to set several independent valve chambers in integrated valve body for body.

The utility model is simple in structure compared with prior art, and failure rate is few, easy to operate, energy saving and making material Material, production cost is relatively low, and once-through operation can complete several delivery tube passages and alternately open and close.

The operation principle of the application is that have several independent flow channel entry points and runner exit in several valve bodies, they pass through Intermediate chamber realizes that the connection of each entrance, each chamber are not connected to mutually independently of each other, in each independent chamber respectively It is provided with independent flap.Flap center is both secured on valve rod, and can be moved up and down with the rotation of valve rod.Flap and valve body Between have space convenient for conveying medium pass through.When rotating clockwise or counterclockwise valve handle（Rotation said herein can be people Can also be that the external force such as motor drive for rotation）Valve rod can be made to move up and down.And several flaps is driven to move.It is moved down on flap It is dynamic can and the convex closing for contact realization runner of valve inner sluice gate, when flap leaves, to explain mouth in valve body convex, opens corresponding runner. It is respectively arranged on valve body cavity top or left part and lower part or right part since the sluice gate in the valve body cavity of the utility model is convex, thus can be real Existing multichannel liquid conducting pipes alternately open and close simultaneously.
