Abstract
The utility model relates to a pneumatic two -way wear -resisting bleeder valve of high temperature, it mainly includes cylinder and valve body, on the cylinder was fixed in the valve body, its piston rod inserts the valve, and this was internal be provided with top discharge mouth and bottom discharge mouth on the valve body all be provided with movable valve plate on top discharge mouth and the bottom discharge mouth all offer flutedly on the opposite face of top discharge mouth and bottom discharge mouth, be provided with the connecting piece and connect two movable valve plates in the recess, the piston rod fixed of connecting piece and cylinder is through being provided with the switch degree that step -by -step solenoid valve comes control flap on the cylinder. The utility model has the advantages of sealing performance is good, and is high temperature resistant, and strong resistance to abrasion opens and close the flexibility, does not have and to close phenomenon not in place, switch put in place accuracy, long service life.
Description
Technical field
This utility model one high temperature pneumatic bidirectional wear resistant outlet valve, is particularly well-suited to air-transport system, is widely used in conveying quartz sand, pulverized limestone, cement, flyash, aluminium oxide etc..Belong to the technical field of valve manufacture.
Background technology
At present, pneumatic gate valve is the major control equipment of a kind of powder, crystal grain material, particulate material and the flow of piece material or conveying capacity, is widely used in the industries such as metallurgy, mine, building materials, grain, chemical industry and controls changes in flow rate or cut off rapidly.The operation principle of pneumatic gate valve, pneumatic gate valve is mainly made up of the part such as framework, flashboard, during work, is moved back and forth in a certain direction by flashboard, reaches the keying purpose of gate.In petrochemical industry, in order to cut off powder material such as PTA, CPE, PVC etc. quickly and easily, often use pneumatic gate valve.Current startup push-pull valve sealing, high temperature resistant and wearability is the most poor, uses limitation relatively big, and opens and closes flexibly, often has closedown incomplete phenomena.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of good seal performance for above-mentioned prior art, and high temperature resistant, wearability is strong, opens and closes flexibly, without closing the high temperature pneumatic bidirectional wear resistant outlet valve of incomplete phenomena.
The technical scheme in the invention for solving the above technical problem is: a kind of high temperature pneumatic bidirectional wear resistant outlet valve, it mainly includes cylinder and valve body, described cylinder is fixed on valve body, its piston rod insertion valve is the most internal, described valve body is provided with top discharge mouth and lower discharge port, described top discharge mouth and lower discharge port are provided with movable valve plate, the opposite face of described top discharge mouth and lower discharge port all offers groove, in groove, it is provided with connector connected by two pieces of movable valve plates, described connector is fixing with the piston rod of cylinder to be connected, the switch degree of valve is controlled by being provided with stepping electromagnetic valve on cylinder.
Preferably, described movable valve plate is sealed by wolfram steel circle with top discharge mouth and lower discharge port.
Preferably, the compression spring fitted tightly with movable valve plate is set at the middle part of described connector.
Compared with prior art, the utility model has the advantage of:
This utility model is applicable to air-transport system, is widely used in conveying quartz sand, pulverized limestone, cement, flyash, aluminium oxide etc., has good seal performance, high temperature resistant, wearability is strong, keying flexibly, without closing incomplete phenomena, switchs the advantages such as accurate, length in service life that put in place.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein:
Cylinder 1, valve body 2, top discharge mouth 2.1, lower discharge port 2.2, movable valve plate 3, wolfram steel circle 4, connector 5, stepping electromagnetic valve 6, compression spring 7.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.
nullAs shown in Figure 1，A kind of high temperature pneumatic bidirectional wear resistant outlet valve in the present embodiment，Including cylinder 1 and valve body 2，Described cylinder 1 is fixed on valve body 2，In its piston rod insertion valve body 2，Described valve body 2 is provided with the top discharge mouth 2.1 being positioned on same centrage and lower discharge port 2.2，Described top discharge mouth 2.1 and lower discharge port 2.2 are provided with movable valve plate 3，Described movable valve plate 3 is sealed by wolfram steel circle 4 with top discharge mouth 2.1 and lower discharge port 2.2，The opposite face of described top discharge mouth 2.1 and lower discharge port 2.2 all offers groove，In groove, it is provided with connector 5 connected by two pieces of movable valve plates 3，Described connector 5 is fixing with the piston rod of cylinder 1 to be connected，The switch degree of valve is controlled by being provided with stepping electromagnetic valve 6 on cylinder 1.
In order to prevent fitting closely between movable valve plate 3 and top discharge mouth 2.1 and lower discharge port 2.2, the compression spring 7 fitted tightly with movable valve plate 3 is set at the middle part of described connector 5, it is ensured that seal during valve closing.
In addition to the implementation, this utility model also includes the technical scheme that other embodiments, all employing equivalents or equivalence substitute mode are formed, within all should falling into this utility model scope of the claims.
