Abstract
The utility model relates to a pneumatic heat preservation discharge valve which is structurally composed of a valve deck, a valve body, a transparent cover, a valve core, a lever, an air cylinder and the like. A straight-through type upper expansion compact type design is adopted for the pneumatic heat preservation discharge valve. Steam is used for heating the valve core and preserving heat of the valve core. The air cylinder pushes a lever mechanism to open and close the valve core. Mesh holes are formed in the circumference of an upper barrel body of the valve core according to material conditions. After expanding upward and being opened, the valve core is communicated with liquid inside a container and is used for discharging materials. After the valve core moves downward and is closed, a sealing ring at the top of the valve core is matched with the valve body so as to realize seal. Due to the adoption of the straight-through type upper expansion compact type design, the pneumatic heat preservation discharge valve is compact in structure in the height direction, large in drift diameter allowed range, tight in sealing, good in heat preserving performance, reliable in motion execution, and smooth in material discharge.
Description
Technical field
The utility model relates to the vent valves that has the liquid-state material of mobile performance in a kind of chemical field, specifically a kind of pneumatic insulation discharge valve.
Background technique
At chemical field, the product needed of some kind is heated as aqueous material and reacts or mix in container, product is cooled to can to become sticky behind the normal temperature or becomes solid and lose flowability, for guaranteeing the smooth discharging of material, do not stop up discharge valve, need to pass to hot medium to discharge valve and be incubated, keep the temperature of setting.
At present, the insulation discharge valve that can buy on market has top extending type insulation discharge valve, bottom open type insulation discharge valve, Thermal insulating ball valve etc.The characteristics of upper exhibition valve and lower exhibition valve are that entrance and exit must have several angle, namely the gateway not on a straight line, but angled, and the valve body of equal latus rectum is large than the ball valve equal-volume, should not select in the occasion that installing space is limited; The Thermal insulating ball valve gateway is straight-through type on same straight line, but for the larger valve body of bore, and solid of rotation can't preheating in the middle of it, heat insulation effect is not good, and some material also is unsuitable for selecting the discharging of revolution kind valve body, causes some occasion to select.
The model utility content
The purpose of this utility model just provides a kind of pneumatic insulation discharge valve, with the problem that solves.
The utility model is achieved in that a kind of pneumatic insulation discharge valve, comprise cut somebody's hair valve gap, valve body, transparent cover, spool, upper back-up ring, lower back-up ring, lever mounting plate, lever bearing pin, lever free bearing, lever, cylinder, cylinder bearing pin, cylinder are cut somebody's hair, air cylinder tailstock bearing pin, spool cut somebody's hair; Above-mentioned discharge valve adopts to open up on the straight-through type opens design, and mesh is offered as the discharge of materials passage in spool top, and spool adopts the steam heating insulation, and spool adopts leverage to open or close.
Described spool is double layer jacket structure, and the internal layer chuck is zone of heating, and outer chuck is thermal-protective coating.
Sealing surface at described valve body is provided with one section column sealed section.
The utility model utilizes cylinder to be used as power, and opens or closes valve.
The utility model adopts on the straight-through type and opens up compact design, and spool adopts the steam heating insulation; Spool promotes leverage by cylinder and opens, closes.
The utility model is comprised of valve gap, seal ring, valve body, O RunddichtringO, transparent cover, spool, lever, cylinder etc.
Wherein, valve body is used for and is connected the heating container connection, and spool moves up and down under the promotion of cylinder and lever, and spool top drum shaft with the internal tank fluid communication, is used for discharge to offering mesh according to the material situation after spool rises; After spool was fallen, spool top seal circle was realized valve seal.
The beneficial effects of the utility model are: straight-through type design, short transverse compact structure, latus rectum allowed band are large, sealing is tight, good heat insulating, action executing is reliable, discharge is smooth and easy.
Description of drawings

Fig. 2 is the side view of pneumatic insulation discharge valve shown in Figure 1.
Fig. 3 is that the A-A of pneumatic insulation discharge valve shown in Figure 1 is to sectional view.
Embodiment
As shown in Figure 1 and Figure 2, the utility model by valve gap 1, seal ring 2, valve body 3, O RunddichtringO 4, transparent cover 5, spool 6, upper back-up ring 7, lower back-up ring 8, lever mounting plate 9, lever bearing pin 10, lever free bearing 11, lever 12, cylinder 13, cylinder cut somebody's hair that bearing pin 14, cylinder cut somebody's hair 15, air cylinder tailstock bearing pin 16, spool cut somebody's hair and 18 etc. form.
Valve gap 1, valve body 3, spool 6 all adopt the stainless steel manufacturing, and seal ring 2 adopts high temperature resistant, anti-corrosive rubber manufacturing.
Valve body 3 is bolted with top heating container, utilizes 4 sealings of O RunddichtringO.
Lever mounting plate 9 in the present embodiment is connected with valve body 3 by bolt, and lever free bearing 11 is connected connection by bolt with the lever mounting plate, and cylinder 13 is connected connection by air cylinder tailstock bearing pin 16 with the lever mounting plate, and cylinder 13 can air cylinder tailstock bearing pin 16 be axis swing.
Spool 6 in the present embodiment is the double-jacket welded structure, and the internal layer chuck is heating resistance collar, and outer chuck is collet.Inner heating resistance collar adopts steam to heat as heat medium, offers vapor inlet port and condensate drain outlet in spool 6 bottoms, and spool 6 endoporus are the discharge of materials passage; Spool 6 also can adopt hot water or heat-conducting oil heating, and corresponding spool 6 structures must add guide plate and set up the gateway separately.
Arrange according to discharges material performance design border mesh in spool 6 tops, when spool 6 after upwards exhibition is opened, material is discharged from the spool endoporus through mesh, when spool 6 move down into the next after, seal ring 2 cooperates valve seal with valve body 3.
Valve gap 1 is connected with spool 6 by stainless steel bolt, and seal ring 2 is fixed on the spool 6.
2 of valve body 3 and seal rings are established one section column sealed section, increase sealing reliability.
6 of valve body 3 and spools are established the sealing of twice O type circle, and one wider annular groove such as static pressure such as grade offered in the centre, prevents that material is from valve body 3 and 6 leakages of spool.
Upper back-up ring 7 and lower back-up ring 8 bear respectively lever thrust up and down, promote to open up to open and move down on the spool 6 to close.
The working procedure of present embodiment is: cylinder 13 cylinder bars stretch out, and promote exhibition on the spool 6 by lever 12, open valve and carry out discharge; Cylinder 13 levers are retracted, and promote spool 6 by lever 12 and move down, and seal ring 2 forms sealing with valve body 3, and valve cuts out.
