Abstract
The utility model relates to a top-guiding discharge valve in a cabin pump low positive-pressure pneumatic conveying system. The main body of the valve is composed of a funnel-shaped valve body and an upper cover fastened and buckled on the valve body, and the funnel outlet port of the valve body is provided with a lower medium passage with a pore diameter equal to the diameter of the valve. The upper cover is provided with a driving shaft pore and an upper medium passage, and the driving shaft pore is provided with a driving shaft. The inner end head of the driving shaft is provided with a flashboard in the radial direction, and the end port plane at the end port in the medium passage of the upper cover and the flashboard swinging and sliding guide plane are in the same plane. The sealing plate face of the flashboard is in a sliding open-and-close sealing fit with the end port plane at the end port in the medium passage of the upper cover.
Description
The utility model relates to a kind of valve, relates in particular to the storehouse pump top-guiding type discharge valve in the low malleation air-transport system of a kind of storehouse pump.
It is to be widely used in production department important techniques fields such as electric power, chemical industry, building materials, mining, metallurgy that strength is carried, and storehouse pump malleation strength output system is simple in structure, and conveying capacity is big, and fed distance is long, is strength output system commonly used.The storehouse pump is the key equipment of this air-transport system.The storehouse pump is provided with operated valves such as feeding valve, discharge valve, suction valve, outlet valve.By discharge port difference is set, draws formula storehouse pump and top-guiding type storehouse pump under the storehouse pump is divided into again.Discharge port is arranged under crying of storehouse pump bottom and draws formula storehouse pump, and what discharge port was arranged in pump top, storehouse is top-guiding type storehouse pump.Because the charging/discharging valve of storehouse pump, outlet valve sealing are paid and directly contacted with fed sheet of a media, operating conditions is abominable, and is very fast with the breakdown speed that metallic material is made.Especially the discharge valve of discharge port is the easiest wearing and tearing, chooses the discharge valve of high-test metal ball valve as top-guiding type storehouse pump, and also only be about half a year general working life.
The purpose of this utility model is to provide a kind of ceramic seal top-guiding type discharge valve.
The technical solution of the utility model is to have adopted a kind of ceramic seal top-guiding type discharge valve, the main body of this valve is made of the loam cake that the funnel-like valve body and the valve body of bottom tightens fastening, funnel exit at valve body has the following medium channel that the aperture equals the valve latus rectum, last cover have drive shaft hole and corresponding with following medium channel on the valve body on medium channel, in drive shaft hole, be equipped with live axle, radially loading is furnished with flashboard on the inner termination of live axle, the port plane at last medium channel inner port place and on the flashboard swing that the covers guide surface of sliding be in same plane, the port planar slide keying at the inner port place of the sealing plate face of flashboard and the medium channel of loam cake is sealed and matched.
Place, the inner of medium channel is provided with a circular groove on loam cake, be embedded with a ceramic ring in the circular groove, the internal diameter of ceramic ring equals the valve latus rectum, the center line of ceramic ring and the center line of medium channel coincide, the port plane of ceramic ring and on the guide surface of the flashboard swing that covers be in same plane.
On flashboard, be embedded with a round ceramic plate with described ceramic ring corresponding position, the diameter of the circular seal face that cooperates with exterior edge face ceramic ring slipper seal ceramic plate is greater than the internal diameter of ceramic ring, when valve closing, the center line of ceramic plate and the central lines of ceramic ring.
Described round ceramic plate is that a cross section is "T"-shaped ceramic plate, the diameter of the large cylinder section of ceramic plate is greater than the ceramic ring internal diameter, the small cylinder section of ceramic plate is flush-mounted in the circular hole of the correspondence on the flashboard, and the exterior edge face of the large cylinder section of ceramic plate and the sealing plate face of flashboard are in the same plane.
The utility model is embedded with ceramic ring at the inner port place of the medium channel at the discharge port place of loam cake, on flashboard, be embedded with ceramic plate with above-mentioned ceramic ring corresponding position, ceramic ring and ceramic plate constitute sealing and pay, because superhard property of stupalith and high wear resistance, so that increase substantially the working life of valve; The funnel-shaped design structural feature of valve body can prevent medium stagnant in valve pocket, has fundamentally solved medium and deposit the interference that causes to ram movement in valve pocket, has guaranteed the reliability of valve motion.
Below in conjunction with accompanying drawing the utility model is further explained and illustrates:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the plan view of Fig. 1.
As shown in Figure 1 and Figure 2, the described top-guiding type discharge valve of the utility model is made of with the loam cake 1 of the fastening fastening of screw the funnel-like valve body 5 of bottom and valve body 5 places suitable for reading.In the bottom of valve body 5 is that funnel exit has the following medium channel that the aperture equals the valve latus rectum.Have on the loam cake 1 drive shaft hole and corresponding with following medium channel on the valve body 5 on medium channel.In drive shaft hole, be equipped with live axle 6, be equipped with seal arrangement between live axle 6 and the drive shaft hole.Radially loading is furnished with flashboard 4 on the inner termination of live axle 6.
In order to improve the working life of valve, the inner port place of medium channel has a circular groove on loam cake 1, be embedded with a ceramic ring 2 in circular groove, the internal diameter of ceramic ring 2 equals the valve latus rectum, the center line of the inner ring surface of ceramic ring 2 and the central lines of last medium channel.The swing slide-and-guide plane of the port plane of ceramic ring 2 and upper cover plate 1 upper flashboard 4 is in the same plane.
For the sealability of improving valve better and the working life of improving valve, the utility model is setting-in one round ceramic plate 3 on flashboard 4 also, ceramic plate 3 and ceramic ring 2 are over against installation, the diameter of the circular seal face of ceramic plate 3 is greater than the internal diameter of ceramic ring 2, and the seal face of ceramic plate 3 is in the sealing plate face of flashboard 4.Round ceramic plate 3 shown in Fig. 2 is "T"-shaped ceramic plate for the cross section, and the large cylinder section exterior edge face of "T"-shaped ceramic plate 3 is the seal face that is sealed and matched with ceramic ring 2, and the small cylinder section of ceramic plate 3 is inlaid in the circular hole of the correspondence on the flashboard 4.The diameter sky of the seal face of "T"-shaped ceramic plate 3 is in the internal diameter of ceramic ring 2.During closed condition, the central lines of the center line of "T"-shaped ceramic plate 3 and ceramic ring 2.
Be equipped with driving swinging arm device radially on the external end head of live axle 6, this device drives the sealing plate face of flashboard and makes arc to swing along the medium channel inner port of loam cake 1 and the guide surface of flashboard swing slip, and valve is opened and closed control.
