Abstract
The utility model relates to a novel gate plate valve, and is a slag discharge valve which is used on the outlet of a slag and slurry pump. The utility model adopts a prismatic four-connecting bar mechanism to connect a door rod and a main and an auxiliary gate plates. The prismatic four connecting bars are made of stainless steel. The pin of each connecting point is made of nylon. The connecting rod is welded with a spacing rod. In the opening and the closing processes, the prismatic four connecting bars are folded, the gate plate is not contacted with a bottom port, and thus the opening and the closing operations are time-saving and labor-saving. When the utility model is closed, the downward moving force of the door rod is stretched and transferred into the tight force for the gate plate and the bottom opening through the prismatic four connecting bars, and thus the tightness is good.
Description
The utility model relates to a kind of gate valve that is used for the outlet of slag stock pump.
The outlet portal of slag stock pump (slag-off valve) answers the requirement of slag stock pump operation must often carry out switching manipulation.And tightly do not leak after requiring to close.Shortcomings such as and existing slag-off valve exists the switching manipulation leakage current of wasting time and energy when cutting out big, and component life is short.
The purpose of this utility model is that a kind of novel slag-off valve will be provided.It is flexible that it has switch, time saving and energy saving.Close tightly and do not leak, advantages such as long service life.
The purpose of this utility model is achieved in that
Existing slag-off valve is the same with existing other gate valve, exists maximum shortcoming to be, the power that the door bar moves up and down is unidirectional all the time.Especially in off position, the power that moves down of door bar can not be transferred on flashboard and the end mouth junction plane effectively.Therefore, the contacting by flashboard and end mouth entirely of the cooperation between the flashboard of slag-off valve and the end mouth.Its cooperation does not have tight power.So, poor sealing, leakage current often makes end mouth junction plane be washed away, and produces adverse consequences.The utility model at first bind mode of opposite house bar and flashboard has been done innovation: adopt the prismatic quadratic crank mechanism that a door bar and the main flashboard of paying are tied.Connecting rod adopts stainless steel to make, and the pin of each node adopts nylon to make, to guarantee four connecting rod activities freely.Four position-limited levers of welding on four connecting rods keep flashboard vertical when opening the door; The cancel all guiding groove; The junction plane of main gate-board and end mouth adopts removable seal ring, and it is made by stainless steel, available heating assembling or dismounting.
When the utility model made valve in off position by the prismatic quadratic crank mechanism, the power of door bar translated into the tight power on flashboard and the end mouth junction plane, so good airproof performance; And four connecting rods draw in switching manipulation, and main gate-board does not contact with end mouth, need not guiding groove in addition, so switch is time saving and energy saving.Because good airproof performance when closing, so no leakage current is end mouth junction plane long service life.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.
Fig. 1 is the durable slag-off valve of the high leak tightness sectional drawing in off position that proposes according to model utility.
Describe details and working condition in detail below in conjunction with Fig. 1 according to the concrete device that the utility model proposes.
This valve is mainly by forming with lower member: prismatic four connecting rods 1, pay flashboard 2, valve body 3, door closure 4, support 5, differential 6, bearing (ball) cover 7, bearing 8, trolley 9, locknut 10, door bar cover 11, rubber cushion 12, door bar 13, valve seals 14, main gate-board 15, position-limited lever 16, bearing 17, flashboard seal ring 18.
When trolley 9 turns clockwise, drive door bar cover 11 rotation in the same way simultaneously.Because door bar cover 11 adopts trapezoidal thread to connect with door bar 13, door bar 13 moves down.Door bar 13 drives with prismatic four connecting rods 1 of its connection and main gate-board 15 again and pays flashboard 2 and moves down.Because the action of gravity of flashboard is closed up prismatic four connecting rods 1 naturally, and main gate-board 15 is not contacted with the seal ring 14 of valve body 3, there is not friction.When the bearing 17 on prismatic four connecting rods 1 contacted on the fulcrum of valve body 3, door bar 13 continued to the power that moves down prismatic four connecting rods 1 to be stretched out, and was close on the end mouth of valve body 3 thereby make main gate-board 15 and pay a flashboard 2.Because each binding site of prismatic four connecting rods 1 is movingly, this tight power is uniform.
When trolley 9 is rotated counterclockwise, carry on the door bar 13, drive prismatic four connecting rods 1 simultaneously, make it to draw in.So, between main gate-board 15 and the valve seals 14 gap has been arranged, so it is time saving and energy saving to open the door.When the spacing head of door bar 13 contacted door closure 4, gate is standard-sized sheet just in time, but flashboard has not all left the end mouth of valve body 3.On each connecting rod of prismatic four connecting rods 1, all welded position-limited lever 16.They just in time keep the plumbness of two flashboards at this moment, normally carry out to guarantee to close the door next time.
Claims (2)
1, a kind of gate valve that is used for the outlet of slag stock pump, the trolley 9 of this valve is enclosed within on the bar cover 11, and door bar cover 11 adopts trapezoidal thread to connect with door bar 13, door bar 13 is with main gate-board 15 and pay flashboard 2 connections, it is characterized in that a bar 13 and main gate-board 15 and pay employing prismatic four connecting rods 1 connection between the flashboard 2, also welded position-limited lever 16 on each connecting rod.
2, valve according to claim 1 is characterized in that each node of prismatic four connecting rods 1 connects with pin, is movingly.
