Description
Technical field
The utility model relates to valve field, the special-purpose split type lift valve of especially a kind of deduster.
Background technology
In the existing blowing type sack cleaner lift valve is installed generally, lift valve is installed on the pure qi (oxygen) casing (upper box) of deduster, it belongs to the off-line valve, in the time need carrying out reverse jetting deashing to the indoor dust-removal cloth-bag of certain bag, use lift valve that this bag chamber is isolated with regard to needs, make it no longer in running order.Existing lift valve and deduster are generally overall structure, the cylinder that is lift valve vertically is installed on the upper cover plate of deduster pure qi (oxygen) casing, the pure qi (oxygen) casing is equivalent to the valve body of lift valve, and the piston rod of cylinder connects the valve plate of level, and the orifice plate of deduster is equivalent to the valve port of lift valve.By the lifting of cylinder extension and contraction control valve plate, can make the dust-removal cloth-bag passage on the orifice plate be in the opening and closing of fault state, thereby bag chamber can be switched in working order and between the off-line state.
Though above-mentioned lift valve with the whole processing of deduster pure qi (oxygen) casing is widely used, but it has the following disadvantages in processing and in using: 1, lift valve and deduster are the monoblock type processing and fabricating, therefore greatly reduce the machining accuracy and the installation accuracy of lift valve, influenced the reliability of valve working; 2, lift valve can make deduster air-purifying chamber upper cover plate and orifice plate produce distortion under the cylinder thrust when work, and the time has been grown and can cause adjoining weld seam to produce cracking, influences the quality of deduster; 3,, when lift valve occurs than major break down, even need change deduster pure qi (oxygen) casing because loam cake and the valve port and the deduster consubstantiality of lift valve so maintaining and replacing parts are extremely inconvenient, have increased the difficulty of maintenance.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of reasonable in design, install simple, easy to maintenance, change easy, safe and reliable and can guarantee the special-purpose split type lift valve of deduster of deduster operate as normal.
The utility model solves its technical problem and is achieved through the following technical solutions:
The special-purpose split type lift valve of a kind of deduster, comprise cylinder and valve plate, the piston rod of this cylinder connects horizontally disposed valve plate, it is characterized in that: also comprise valve body, valve seat and valve port, valve body reaches a vertical gusset group of making along circumferential uniform interval at its bottom surface by horizontal top plate and constitutes, and cylinder vertically is installed in the horizontal top plate upper surface of valve body, and valve plate is vertically between the gusset group, the bottom surface of this vertical gusset is installed on the valve port of level jointly, and this valve port is coaxial to be inserted in the valve seat.
And the vertical gusset that described horizontal top plate bottom surface is made along circumferential uniform interval is 2～6, has the gap between every two adjacent vertical gussets.
And, clamping a seal between the bottom surface of described vertical gusset and the valve port, the extension limit sealing top of sealing part is pressed in the inwall of valve seat.
Advantage of the present utility model and beneficial effect are:
1, this split type lift valve is a frame-type independence connected structure, and it can separate machined with deduster, so has greatly improved the machining accuracy and the installation accuracy of lift valve, has reduced site operation mounting hardness and cost, has strengthened the reliability of valve working.
2, this split type lift valve adopts independent processing mode, can guarantee that the product that processes has good reliability, uniformity and interchangeability, is convenient to realize industrialization large-scale production, for industrialization, the modularization of deduster production are opened up precedent.
Advantages such as 3, this split type lift valve has that manufacturing time is short, production cost is low, convenient transportation and freight charges are low.
4, this split type lift valve can not damage deduster air-purifying chamber upper cover plate and orifice plate when work, can guarantee the deduster operate as normal, prolongs the service life of deduster.
5, this split type lift valve is an absolute construction, it can be taken out from deduster and keep in repair, and has reduced the difficulty of maintenance, has improved the efficient of maintenance, has saved the time and the cost of maintain and replace, has improved the deduster total quality.
6, the special-purpose split type lift valve of deduster that the utility model is a kind of reasonable in design, plug-in mounting and convenience easy to maintenance, production cost is low, this lift valve is an absolute construction, standardization large-scale production can be realized, numerous unfavorable factors that site operation brings can be stopped.

The specific embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
The special-purpose split type lift valve of a kind of deduster comprises cylinder 2 and valve plate 4, and the piston rod of this cylinder connects horizontally disposed valve plate.Innovative point of the present utility model is: also comprise valve body, valve seat 5 and valve port 9, valve body is made of horizontal top plate 1 and vertical gusset group 3, vertically the vertical gusset in the gusset group is formed on the bottom surface of horizontal top plate along circumferential uniform interval, vertically the quantity of gusset is generally 2～6, in the present embodiment be four, have ventilative gap between every two adjacent vertical gussets.Cylinder vertically is installed in the upper surface of horizontal top plate, and horizontal top plate is installed in by bolt on the upper cover plate 6 of pure qi (oxygen) casing 7, and the valve plate that is connected with cylinder is vertically between the gusset group.
Vertically the bottom surface of each the vertical gusset in the gusset group all is installed on the valve port of level jointly by bolt, and this valve port is coaxial to be inserted in the valve seat, and this valve seat can be installed on the orifice plate 10 of deduster by bolt.Clamp a seal 8 between the bottom surface of vertical gusset and valve port, the extension limit sealing top of sealing part is pressed in the inwall of valve seat.The sealing part can be O-ring seal, also can be independent sealing gasket.
The utility model comprises frame-type main body and two independent sectors of valve seat, adds and can process respectively man-hour, earlier valve seat is installed in by bolt on the orifice plate of deduster during installation, the frame-type main body is inserted in the valve seat to get final product again.When deduster was worked, the cylinder of lift valve was by the lifting of telescopic drive valve plate, and valve plate can make valve port open or sealing, finally makes the dust settling pocket chamber be in work or off-line state.
