Description
Technical field
The utility model relates to a kind of contracting being mainly used in realizing the multiple aperture conversion of air shut-off valve valve inner and blocks up transformational structure.
Background technique
At present, in the use of air shut-off valve, usually need according to actual conditions, utilize the size in vent aperture to control the flux magnitude of air pressure between each chamber of air shut-off valve valve inner, and the existing structure for controlling flux magnitude is comparatively complicated, run stable not.
Model utility content
Goal of the invention of the present utility model is: for above-mentioned Problems existing, provides a kind of compact structure, can realize the conversion of multiple aperture, block up transformational structure to meet air shut-off valve to the contracting that aperture requires.
The technical solution of the utility model is achieved in that the stifled transformational structure of a kind of contracting, it is characterized in that: comprise contracting blocked shot and the stifled cover of contracting, described contracting is blocked up cover and to be socketed on contracting blocked shot and to be threaded with it, the radial direction through hole described contracting blocked shot being provided with central through bore and being communicated with central through bore, the stifled cover of described contracting is connected with air shut-off valve valve seal, controls the opening and closing of radial direction through hole on described contracting blocked shot by rotating contracting blocked shot.
Transformational structure is blocked up in contracting described in the utility model, it is fixedly connected with the stifled pad of contracting in described contracting blocked shot underpart, the equal forming station stage structure in two ends up and down of described contracting blocked shot, make it mobile relative to the stifled cover of contracting by positive and negative rotation contracting blocked shot, and utilize the step surface of contracting blocked shot two ends ledge structures to overlap coordinating of both sides end face with contracting to block up, control the opening and closing of radial direction through hole on described contracting blocked shot.
Transformational structure is blocked up in contracting described in the utility model, and the stifled cover of contracting described in it is tapered, the stifled cover of described contracting with adopt tapered thread to be connected between air shut-off valve valve body seal, block up the upper-end surface overlapped at described contracting blocked shot and be respectively arranged with straight groove or cross recess with contracting.
The utility model utilizes bolton principle, by forward and reverse rotation contracting blocked shot, realize the opening and closing of radial direction through hole on contracting blocked shot, and central through bore is in connected state all the time on contracting blocked shot, like this, by the opening and closing of radial direction through hole, achieve the conversion in multiple aperture, effectively control the size of air flux, to meet air shut-off valve requirement to aperture under different demand.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the stifled transformational structure of a kind of contracting, comprise contracting blocked shot 1, the stifled cover 2 of contracting and the stifled pad 3 of contracting, described contracting is blocked up cover 2 and to be socketed on contracting blocked shot 1 and to be threaded with it, the radial direction through hole 5 described contracting blocked shot 1 being provided with central through bore 4 and being communicated with central through bore 4, described contracting blocks up pad 3 by welding, riveted joint, gland or alternate manner are fixedly connected on contracting blocked shot 1 underpart, the equal forming station stage structure in two ends up and down of described contracting blocked shot 1, it is made to move relative to the stifled cover 2 of contracting by positive and negative rotation contracting blocked shot 1, and utilize the step surface of contracting blocked shot 1 two ends ledge structure to block up coordinating of cover 2 both sides end face with contracting, control the opening and closing of radial direction through hole 5 on described contracting blocked shot 1, wherein, it is tapered that cover 2 is blocked up in described contracting, described contracting is blocked up and is adopted tapered thread to be connected between cover 2 with air shut-off valve valve body 6 to seal, straight groove or cross recess is respectively arranged with in the upper-end surface of the stifled cover 2 of described contracting blocked shot 1 and contracting, easily stifled for contracting transformational structure can be disassembled in air shut-off valve valve body, maintainable strong.
As shown in Figure 2, rotate forward contracting blocked shot, when lower end surface and the contracting of the ledge structure of contracting blocked shot upper end portion is stifled put end face fit time, radial direction through hole on described contracting blocked shot is positioned at the contracting blocked shot threaded joints that overlap stifled with contracting, air pressure only can enter valve body from the central through bore of contracting blocked shot central authorities, now realizes the conversion of small aperture; As shown in Figure 3, change being in the contracting stall shown in Fig. 2 in structural entity screw-in valve body with a word screwdriver or cross screwdriver, the connection realizing the stifled transformational structure of contracting and valve body seals.
As shown in figs. 1 and 4, counterrotating contracting blocked shot, when contracting stifled pad upper-end surface and the contracting of contracting blocked shot underpart ledge structure is stifled overlap lower end surface fit time, the radial direction through hole of described contracting blocked shot is opened, air pressure can not only enter valve body from the central through bore of contracting blocked shot central authorities, can also enter valve body from the radial direction through hole of contracting blocked shot, the flux sum of central through bore and radial direction through hole is equal to the flux of a macropore, thus achieves wide-aperture conversion.
The utility model compact structure, utilizes bolton principle, makes two working positions all can realize locating function, realizing small aperture conversion, realizing large aperture conversion by counterrotating compression contracting stifled cover other end by rotating forward compression contracting stifled cover end face.And according to actual conditions, the radial direction through hole on described contracting blocked shot axially can arrange many groups along contracting blocked shot, by controlling the opening and closing of different radial direction through hole, realize the object of air shut-off valve valve inner multiple aperture conversion.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
