Described valve pocket is made up of valve pocket lid and valve cage, the upper support hole that valve pocket lid center is provided with steam vent and is used to install spool.The steam vent end opening that valve pocket covers is provided with sealing ring, and described valve pocket covers and is used to install around the upper support hole of spool, also is provided with pore.
The inside, lower end of described valve cage is provided with the gas-water separation net, and gas-water separation net center is provided with the lower support hole that is used to install spool.Gas-water separation is used to install around the lower support hole of spool plug on the net, also is provided with pore.Above-mentioned valve pocket lid and valve cage are on the same axis.
Further technical scheme of the present utility model is: above-mentioned two ball floats and connecting rod are overall structure;
Further technical scheme of the present utility model is: the gas-water separation net of its inside, valve cage lower end, multilayer can be set, and the mesh of each layer separate mesh is interlaced arranges; Undermost gas-water separation net and valve cage connect the location with interior jump ring.
Further technical scheme of the present utility model is: above-mentioned valve pocket lid and valve cage adopt and are threaded, and the top boss of valve pocket lid is an outer-hexagonal shape.
Further technical scheme of the present utility model is: between described air self-checking device and the valve body, employing is threaded.Between described valve pocket lid and the valve body, be provided with sealing ring.
The utility model is owing to adopted two ball floats, and link to each other by connecting rod between two ball floats, and be located on the same axis, at first promoting following ball float when water level is risen rises, valve-off before water level reaches the top ball float, air drains into upper chamber in this process from the steam vent that valve pocket covers simultaneously, enter atmosphere by upper chamber again, if contain a small amount of spray in institute's emptying gas, spray falls after running into the gas-water separation net of inside, valve cage lower end, air is then discharged smoothly, thereby has prevented the water spray leakage phenomenon.Because the sliding support hole is located at the connecting rod two ends, no jam phenomenon operates steadily.Be located at the gas-water separation net of inside, valve cage lower end, can also stop foreign material in the water, make valve switch more reliable the influence of valve, and simple in structure, requirement on machining accuracy is low, is convenient to make.
Description of drawings
Below in conjunction with embodiment of accompanying drawing narration, the utility model is described in further detail;
Fig. 1 is the structural representation of a preferred embodiment of the utility model, wherein:
Jump ring in 1,2 aqueous vapor separate meshes, 3 valve bodies, 4 valve pockets lid, pore on 5 valve bodies, the sealing ring between 6 valve pockets lid and valve body, the sealing ring of 7 steam vent end openings, 8 upper floating balls, 9 connecting rods, 10 times ball floats, 11. separation sleeve, 12 valve cages, 13 steam vents, 14 upper chamber, 15 lower chambers, 16 lower support holes, pore around the pore of 17 aqueous vapor separate meshes, 18 upper support holes, 19 upper support holes.
The specific embodiment
Present embodiment is as shown in Figure 1:
Include the valve body 3 of upper chamber 14 and lower chambers 15 and be installed on the interior air self-checking device of valve body; Described air self-checking device comprises being installed on the valve pocket that has spool between upper chamber 14, the lower chambers 15.Described spool is made up of upper floating ball 8, following ball float 10 and connecting rod 9, and is on the same axis.Described valve pocket is made up of valve pocket lid 4 and valve cage 12, the upper support hole 19 that valve pocket lid center is provided with steam vent 13 and is used to install spool; Steam vent 13 end openings on the valve pocket lid 4 are provided with sealing ring 7.Also be provided with pore around being used to install the upper support hole 19 of spool on the valve pocket lid 4.The inside, lower end of valve cage 12 is provided with aqueous vapor separate mesh 2, and this aqueous vapor separate mesh center is provided with the lower support hole 16 that is used to install spool, also is provided with pore 18 around it.Above-mentioned valve pocket lid 4 and valve cage 12 are on the same axis.
Upper floating ball 8 is an overall structure with following ball float 10 and connecting rod 9.The aqueous vapor separate mesh 2 of its inside, valve cage 12 lower end can be provided with multilayer, and multilayer gas-water separation net 2 is separated by separation sleeve 11, and the pore of each layer separate mesh 2 is interlaced arranges.Undermost gas-water separation net 2 is connected the location with the interior jump ring 1 of valve cage 12 usefulness.
Adopt between above-mentioned valve pocket lid 4 and the valve cage 12 and be threaded.The top boss of valve pocket lid 4 is an outer-hexagonal shape, is convenient to installation and removal.
Described air self-checking device adopts with valve body 3 and is threaded.Be provided with sealing ring between valve pocket lid 4 and the valve body 3.
The operating principle of present embodiment and course of action are achieved in that when the water level rising enters lower chambers 15, the following ball float 10 that the water level that rises at first promotes spool rises, the pore 17 of air from the aqueous vapor separate mesh 2 of valve cage 12 lower ends in this process simultaneously, the set steam vent 13 in center below the valve pocket lid 4, pore 18 on the valve pocket lid 4 around the supported hole 19, discharge in the pore 5 on the valve body 3, might have a small amount of spray in the process that water level rises, these sprays fall after running into the aqueous vapor separate mesh, air is then discharged smoothly, valve-off before the steam vent 13 below water level reaches valve pocket lid 4, thus the water spray leakage phenomenon prevented.This moment, upper chamber 14 isolated between the lower chambers 15 fully, and lower chambers 15 no longer communicates with atmosphere.And when drawdown, follow weakening of ball float buoyancy, and spool moves downward gradually until the depressurization state, and at this moment, air can enter lower chambers 15 from the outside again.Circulate with this, guarantee that lower chambers 15 is always antivacuum state.
Because the utility model has adopted two ball direct dynamic structures, can reliably aqueous vapor be separated, prevented the water spray leakage phenomenon, guarantee that lower chambers 15 is always antivacuum state.
