Model utility content
The utility model aims to provide a kind of plug-in type air throttle, and this air throttle can be used for using when Integrated valve is installed.
To achieve these goals, the technological scheme that the utility model adopts is:
A kind of plug-in type air throttle, comprises
-valve body, it has gas-entered passageway, inner chamber and outlet passageway;
-be fixed on valve gap on valve body;
-be arranged on diaphragm unit between valve body and valve gap, for gas-entered passageway, inner chamber and outlet passageway are ganged up into gas channel on this diaphragm unit; And
-spool, it is moved up and down by fixing diaphragm unit thereupon and realizes ganging up or cut off described gas channel; Its structural feature is, the entrance of described gas-entered passageway is arranged on the bottom of valve body, and the outlet of described outlet passageway is arranged on the side wall surface of valve body.
Thus, when gas pressure overcomes the downforce of diaphragm unit, spool moves, and gas enters from body base, and flow out from body wall after inner chamber and outlet passageway, valve open, realizes air feed.When gas pressure is not enough to the downforce overcoming diaphragm unit, spool moves down, and cuts off described gas channel, thus realizes valve closing.
According to embodiment of the present utility model, can also do further to optimize to the utility model, the technological scheme below for being formed after optimization:
In order to prevent Leakage Gas, between described diaphragm unit and valve gap, being provided with sealing gasket, between this diaphragm unit and valve body, being provided with lower seal pad.Further, in order to ensure sealing effect, between described upper sealing gasket and valve gap, be provided with briquetting.
In order to ensure the uniform compaction pressure of diaphragm, the upper surface of described diaphragm unit is provided with diaphragm follower, and upper holder block is equipped with on the top of described valve gap, is provided with the elastic element of pretension between diaphragm follower and upper holder block.Preferably, described elastic element is Compress Spring.
What conveniently regulate air throttle passes through pressure size, and described valve gap is provided with the pressure adjusting structure regulating diaphragm follower impacting force.Preferably, described pressure adjusting structure is the adjusting bolt and the nut that are contained in valve gap top, and described upper holder block is pressed in the bottom of this adjusting bolt.When needing intensified pressure, after screwing adjusting bolt, with nut check, otherwise in like manner.
In order to ensure when gas pressure is not enough the reliability cutting off gas channel, the bottom of described spool is coniform, this spool is positioned at directly over the import of outlet passageway, thus, when gas pressure is on the low side, spool moves down, the import of outlet passageway is placed in bottom spool, thus shutoff gas channel, otherwise spool departs from outlet passageway and keeps gas channel unimpeded.
In order to improve the sealability of valve body further, the junction of described valve body and valve gap is provided with outside thread, and described valve gap has the internal thread coordinated with this outside thread.
Preferably, described spool top has screw thread, is provided with little sealing gasket between spool and diaphragm unit; Described spool is connected with a locking nut screw-thread fit and spool, little sealing gasket, diaphragm unit, the pressing plate being arranged on diaphragm unit upper surface and the spring washer be sleeved on spool is connected into an one-piece element.
Compared with prior art, the beneficial effects of the utility model are:
1) for integrated installation provides a kind of plug-in type air throttle;
2) valve body technology capability is good, and structure is simple, attractive in appearance;
3) as an independently valve, each technical parameter and inspection can be set separately, assembling and fast easy to maintenance.
Below in conjunction with drawings and Examples, the utility model is further elaborated.
Accompanying drawing explanation
Fig. 1 is the structure principle chart of the utility model embodiment;
Fig. 2 is the structural representation of valve body in Fig. 1.
Embodiment
A kind of plug-in type air throttle, as shown in Figure 1, form primarily of valve body 1, spool 2, little sealing gasket 3, diaphragm unit 4, diaphragm pressing plate 5, lower seal pad 6, upper sealing gasket 7, lower lock block 8, spring washer 9, locking nut 10, Compress Spring 11, upper holder block 12, label 13, regulator bolts 14, locking nut 15 and valve gap 16.
Shown in Fig. 1 and 2, valve body 1 is a step-like solid of rotation, and large end periphery car has outside thread to be connected with valve gap 16, inner cavity is air cavity c, middle regular hexahedron d place is spanner position, and lower end screw thread is connected with external harmoniousness allocation block, and there is air inlet inside and two passes of giving vent to anger.Valve body 1 large end face small groove is equipped with lower seal pad 6.Spool 2, little sealing gasket 3, diaphragm unit 4, diaphragm pressing plate 5, spring washer 9 and locking nut 10 form parts.Spool 2 has held as cylindrical facing cut symmetrical two planes greatly, mills part for gas channel.Diaphragm unit 4 is contained on lower seal pad 6, diaphragm unit 4 is equipped with sealing gasket 7, and lower lock block 8 flattens upper sealing gasket 7.Lower seal pad 6 and upper sealing gasket 7 seal, and prevent air from entering in air cavity.Compress Spring 11 is cylindroid helicalcoil compression spring, and one end is arranged in diaphragm pressing plate 5 plane, and the other end is equipped with upper holder block 12, after regulator bolts 14 installing locking nut 15 and label 13, then is arranged on valve gap 16.
The mode of execution of plug-in type cryogenic insulated cylinder air throttle: during setting pressure, unclamp locking nut 15, turn clockwise regulator bolts 14, bolt down does straight line motion, promotes upper holder block 12 descending, Compress Spring 11, under spring force, there is deformation in diaphragm unit 4, produces inner prestressing force, and the conical surface and the valve body air outlet hole place that promote spool 2 seal.B hole is inlet hole, pressed gas enters from b hole and arrives medium air cavity c, after being full of air cavity c, active force is produced to diaphragm, if pressure medium gas is greater than diaphragm deformation prestressing force, diaphragm is upwards out of shape, Compress Spring 11, band movable valve plug 2 leaves valve body, in air cavity c, gas flows out from a hole, and form a path, gas is able to preferential use.Like this, both reduce a bottle internal air pressure, and directly can use gas again, eliminate vaporescence, serve safe and economic solar term effect.When the pressure medium gas come from b hole is less than diaphragm deformation prestressing force, spool and valve body are fitted, and block gas in air cavity c and flow out from a hole.Now do not re-use gas in bottle, and use liquid medium from another pipeline.Turn clockwise regulator bolts 14, and bolt is Compress Spring more down, and diaphragm deformation is larger, and deformation prestressing force is larger, and cracking pressure is larger.Otherwise be rotated counterclockwise regulator bolts 14, bolt more up moves, the active force of spring diminishes, and diaphragm deformation is less, and cracking pressure is less.
Valve body is carried out innovative design by the utility model, is designed to a stepped shaft cylindrical body, and there is air inlet inside and two passes of giving vent to anger.Have a spill air cavity in the large end of diameter, external belt outside thread is connected with valve gap, and middle part cylindrical car has outside thread to be connected with integrated allocation block.Valve body technology capability is better, and structure is simpler and attractive in appearance.It, as an independently valve, can set separately each technical parameter and re-use after the assay was approved, safe and reliable, fast easy to maintenance.
The content that above-described embodiment is illustrated should be understood to these embodiments only for being illustrated more clearly in the utility model, and be not used in restriction scope of the present utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen into the application's claims limited range.
