Description
Technical field
The utility model relates to the valve class, particularly a kind of vacuum sampling cock.
Background technique
A kind of existing vacuum sampling cock, include valve body, be arranged on the valve gap on the valve body, be provided with valve pocket in the valve body, valve gap is provided with the inlet passage that enters valve pocket for medium, be arranged on and be used for the inlet control valve that control media enters valve pocket in the inlet passage, also be provided with on the valve gap and be used to connect valve pocket and extraneous venting channels, in venting channels, be provided with and be used to control the breather valve that valve pocket is in communication with the outside, also be provided with the outlet passage that flows out valve pocket for medium on the valve body, in outlet passage, be provided with the discharge control valve that control media flows out valve pocket, in use, open inlet control valve earlier, close breather valve and discharge control valve, allow medium flow into valve pocket; Close inlet control valve again, open breather valve and discharge control valve, allow medium flow out valve pocket, take a sample.But the vacuum sampling cock of this structure need be controlled three valves, complex structure, and processing and use are inconvenient.
Summary of the invention
The purpose of this utility model: in order to overcome the defective of prior art, the utility model provides vacuum sampling cock a kind of simple in structure, easy to use.
The technical solution of the utility model: a kind of vacuum sampling cock, include valve body, valve pocket, valve gap, described valve gap is provided with the inlet passage and the venting channels that is used to be connected the valve pocket and the external world that flows into valve pocket for medium, valve body is provided with for medium and flows out the outlet passage of valve pocket and be arranged on the discharge control valve that is used for control media outflow valve pocket in the outlet passage, described valve gap includes the bonnet of split, the bottom flange that cooperates with the bonnet rotation, described bottom flange is fixedlyed connected with valve body, also be provided with the fixing device that is used for fixing axial displacement between bonnet and the bottom flange between described bonnet and the bottom flange, described bonnet is provided with ostium and vent, described bottom flange is provided with through hole, described ostium, the central shaft position of vent and through hole equates with distance between the running shaft of described bottom flange, described ostium is communicated with the described inlet passage of formation with through hole, described vent is communicated with the described venting channels of formation with through hole.Adopt technique scheme, only a discharge control valve need be set, just can realize that medium enters valve pocket and medium flows out valve pocket, simple in structure, easy to use.
Further improvement of the utility model: described fixing device includes bolt, nut, pressure regulating spring, described bonnet of described bolt-through and bottom flange, the end that described bolt is positioned at valve pocket is fixedlyed connected through welding with bottom flange, described nut sleeve is located at and is positioned on the outer bolt of valve gap, and described pressure regulating spring is between described nut and bonnet.Adopt above-mentioned further improvement, make bonnet and bottom flange fixing reliable, simple in structure.
Further improvement more of the present utility model: described vent and extraneous joint are provided with some filter clothes.Adopt above-mentioned further improvement again, can prevent that introduced contaminants from entering in the valve pocket, the result of influence sampling.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment.
Embodiment
As shown in Figure 1, a kind of vacuum sampling cock, include valve body 1, valve pocket 2, valve gap 3, described valve gap 3 is provided with the inlet passage 4 and the venting channels 5 that is used to be connected the valve pocket 2 and the external world that flows into valve pocket 2 for medium, valve body 1 is provided with for medium and flows out the outlet passage 6 of valve pocket 2 and be arranged on the discharge control valve (not shown) that is used for control media outflow valve pocket 2 in the outlet passage 6, described valve gap 3 includes the bonnet 31 of split, the bottom flange 32 that cooperates with bonnet 31 rotations, described bottom flange 32 is fixedlyed connected with valve body 1, also be provided with the fixing device 7 that is used for fixing axial displacement between bonnet 31 and the bottom flange 32 between described bonnet 31 and the bottom flange 32, described bonnet 31 is provided with ostium 41 and vent 51, described bottom flange 32 is provided with through hole 8, described ostium 41, the central shaft position of vent 51 and through hole 8 equates with distance between the running shaft of described bottom flange 32, in this specific embodiment, described described ostium 41, vent 51 and through hole 8 are cylindrical hole, described ostium 41 is communicated with the described inlet passage 4 of formation with through hole 8, described vent 51 is communicated with the described venting channels 5 of formation with through hole 8.
In this specific embodiment, described fixing device 7 includes bolt 71, nut 72, pressure regulating spring 73, described bolt 71 runs through described bonnet 31 and bottom flange 32, the end that described bolt 71 is positioned at valve pocket 2 is fixedlyed connected through welding with bottom flange 32, described nut 72 is set on the bolt 71 that is positioned at outside the valve gap 3, and described pressure regulating spring 73 is between described nut 72 and bonnet 31.Described pressure regulating spring 73 can prevent effectively that stuck phenomenon appears in nut 72 when rotation bottom flange 32.In this specific embodiment, described fixing device 7 is arranged on the axial corresponding position of described bonnet 31, bottom flange 32, can guarantee the stationarity of valve gap 3 like this.
