Description
Technical Field
The invention relates to a gate valve of a fluid conveying pipeline, in particular to a multi-path fluid pipeline alternating opening and closing valve.
Background
In industries such as industry, agriculture, and environmental protection, it is more common for multiple fluid conveying pipelines to be vertically stacked and transversely arranged in parallel, and it is not uncommon to open several pipe gate valves and close other several pipe gate valves simultaneously. Taking the water treatment filter membrane flushing work as an example, in a water treatment filtering device, after a filtering material is filtered for a period of time, a plurality of filtering holes are blocked, the filtering material needs to be flushed on the front side and the back side, and particularly, the filtered water needs to be flushed when the back side is flushed. In this operating mode, four flow paths are formed, namely a raw water inlet, a purified water outlet, a rinsing water inlet and a rinsing water outlet. When water is normally produced (filtered water), the raw water inlet and the purified water outlet are opened, and the washing water inlet and the washing water outlet are closed. When flushing, the valve opening and closing states are reversed. The traditional process flow uses a plurality of solenoid valves. And the control system is used to control the valve. The four pipeline gate valves are opened and closed alternately in pairs, and water making and flushing are realized. However, in the mode, the number of valves is large, the pipeline is complex, the failure rate is high, and the control also needs separate hardware and software, so that more resources are consumed.

The invention aims to realize the purpose by the following technical scheme that the multi-path fluid pipeline alternate opening and closing valve comprises a valve body, a valve cavity, a valve clack, a valve rod, a flow channel inlet connected with a fluid inlet pipe and a flow channel outlet connected with an outlet, and is characterized in that: the valve body is arranged on the same vertical plane or plane, the gate in the valve body cavity opened at one time or a plurality of times is arranged on the upper part or the left part of the valve cavity in a protruding mode, the valve gate in the valve body cavity closed at one time is arranged on the lower part or the right part of the valve cavity in a protruding mode, the gate is sleeved with an anti-friction protective sleeve or a protective block, the middle of the valve clack is fixedly connected onto the valve rod, each valve clack is arranged in the middle of each valve cavity, the valve rod penetrates through the middle of each valve body, the upper part of the valve rod is provided with threads and is sleeved with a nut seat fixedly connected onto the valve body at the top or the left part, the top end of the valve rod is fixedly connected with a handle or.
The number of the valve bodies is 2-20.
The handle is a straight handle or a disc-shaped handle.
The valve cavity can be cylindrical or rectangular.
The valve clack is round or rectangular.
The valve bodies can be respectively independent split valve bodies or designed into an integral valve body, and a plurality of independent valve cavities are arranged in the integral valve body in an up-down overlapping or left-right parallel arrangement mode.
Compared with the prior art, the invention has the advantages of simple structure, less failure rate, simple and convenient operation, energy and manufacturing material saving and lower production cost, and can complete the alternate opening and closing of a plurality of conveying pipe channels by one-time operation.
The working principle of the valve is that a plurality of independent flow channel inlets and flow channel outlets are arranged in the valve bodies and are communicated with each other through the middle chamber, the chambers are independent from each other and are not communicated with each other, and the independent valve clacks are arranged in the independent chambers respectively. The valve clack center is fixed on the valve rod and can move up and down along with the rotation of the valve rod. A space is reserved between the valve clack and the valve body, so that a conveyed medium can pass through the space. When the valve handle is rotated clockwise or anticlockwise (the rotation can be manual rotation or driven by external force such as a motor and the like), the valve rod can move up and down. And drives the valve clacks to move. The valve clack moves up and down to contact with the gate opening in the valve body to close the flow channel, and when the valve clack leaves the valve body, the gate opening is convex, and the corresponding flow channel is opened. The gate bulges in the valve body cavity are respectively arranged at the upper part or the left part and the lower part or the right part of the valve body cavity, so that the multi-path liquid conveying pipelines can be alternately opened and closed at the same time.

Detailed Description
The invention will be further described with reference to embodiments in accordance with the accompanying drawings; the multi-way fluid pipeline alternately opens and closes the valve, here the said fluid can be the medium that the flow of liquid or gas can be transported by the pipeline; the multi-way fluid pipeline refers to 2-20 ways. For convenience of illustration, the four-way water treatment pipeline is taken as an example in the present embodiment, as shown in fig. 1, the present embodiment adopts an integrated four-way fluid pipe alternating on-off valve, which includes a valve body 14, a valve rod 9, a first flow channel inlet 1, a second flow channel inlet 2, a third flow channel inlet 3, a fourth flow channel inlet 4, a first flow channel outlet 5, a second flow channel outlet 6, a third flow channel outlet 7, a fourth flow channel outlet 8, a first valve flap 10, a second valve flap 11, a third valve flap 12, a fourth valve flap 13, and a valve handle 15. The valve body 14 is characterized by comprising a flow channel inlet 1 and a flow channel outlet 5; a flow channel inlet 2 and a flow channel outlet 6; a flow channel inlet 3 and a flow channel outlet 7; the runner entry 4 and the runner exit 8 are respectively isolated into four independent chambers, the centers of the first valve clack 10, the second valve clack 11, the third valve clack 12 and the fourth valve clack 13 are respectively and fixedly connected with the valve rod 9, the valve clack is placed in the four independent chambers in the middle, the gate openings on two valve bodies which are opened simultaneously are convexly arranged on the upper part of the valve cavity, the valve gate openings on the two valve bodies which are closed simultaneously are convexly arranged on the lower part of the valve cavity, and if the valve cavities are arranged in parallel on the plane, the gate openings in the valve cavities are convexly arranged left.
