Description
Technical field
The present invention relates to valve technology field.It particularly relates to a kind of pneumatic control valve.
Background technology
The most general pneumatic control valve, general employing screw thread carries out valve body to be fixed.This structure causes pneumatic control valve dismounting to be difficult to.Not only increase manual labor intensity, and after being dismounted for multiple times, easily occur that data are inaccurate, the problem that error is bigger.Additionally, existing pneumatic control valve typically uses soft seal to be airtight and watertight padding, the most do not use hard sealing to be because using hard sealing can there is leakage defect, but using soft seal to equally exist, wearability is poor causes shorter problem in service life.Therefore, how solving the problems referred to above is the direction that those skilled in the art need research.
Summary of the invention
For solving the problems referred to above, the invention provides a kind of pneumatic control valve.
Its scheme used is as follows:
A kind of pneumatic control valve, including: valve body, spool, valve rod, bonnet, and Pneumatic actuator；Described bonnet, is connected with valve body by bolt；Described spool is positioned at valve body, and described valve rod through bonnet, and is fixed as one with spool；Described Pneumatic actuator includes performing cylinder, air cylinder support and black box；The outfan of described execution cylinder connects valve rod, drives valve rod to do upper and lower straight and becomes motion, band movable valve plug conducting/close stifled valve body；Described execution cylinder is installed on air cylinder support, and described air cylinder support is connected with bonnet, and the junction of valve rod and bonnet, is located at by described black box.
By using this technical scheme: do upper and lower Direct Travel by execution cylinder and move, band ovable valve stem and spool synchronize to move up and down, it is achieved regulate the automatization of spool position.
Preferably, in above-mentioned pneumatic control valve: described black box includes airtight and watertight padding, airtight and watertight padding gland and pressing plate；Airtight and watertight padding gland is pressed in airtight and watertight padding by described pressing plate, and the junction of valve rod and bonnet, is located in described airtight and watertight padding.It is further preferred that described airtight and watertight padding uses tetrafluoroethylene-perfluoro alkoxy vinyl ethers copolymer (i.e. PFA) to constitute.
By using this technical scheme: constituted airtight and watertight padding with tetrafluoroethylene-perfluoro alkoxy vinyl ethers copolymer, improve the service life of airtight and watertight padding.
It may further be preferable that in above-mentioned pneumatic control valve: described Pneumatic actuator also includes aperture rule and aperture pointer；Being carved with aperture scale on described aperture rule, be fixed on the side performing cylinder outfan, described aperture pointer connects the outfan performing cylinder, is synchronized with the movement with valve rod, and its needle point is just to the aperture scale on aperture rule.
By using this technical scheme: utilize aperture pointer and the cooperation of aperture rule, it is achieved the precise management to spool regulation aperture.
Compared with prior art, present configuration is simple, it is easy to accomplish.It is capable of fast assembling-disassembling, reduces cost, it is achieved that automatization's regulation of aperture.

Detailed description of the invention
Embodiments of the invention 1 as Figure 1-3:
A kind of pneumatic control valve, including: valve body 1, spool 2, valve rod 3, bonnet, 4 and Pneumatic actuator 6；Described bonnet, 4 is connected with valve body 1 by bolt 5；Described spool 2 is positioned at valve body 1, and described valve rod 3 through bonnet, 4 and is fixed as one with spool 2；
Described Pneumatic actuator 6 includes performing cylinder 61, air cylinder support 62, black box 63, aperture rule 64 and aperture pointer 65；The outfan of described execution cylinder 61 connects valve rod 3, drives valve rod 3 to do upper and lower straight and becomes motion, and band movable valve plug 2 turns on/close stifled valve body 1；Described execution cylinder 61 is installed on air cylinder support 62, and described air cylinder support 62 is connected with bonnet, 4, and the junction of valve rod 3 and bonnet, 4 is located at by described black box 63.Being carved with aperture scale on described aperture rule 64, be fixed on the side performing cylinder 61 outfan, described aperture pointer 65 connects the outfan performing cylinder 61, is synchronized with the movement with valve rod 3, and its needle point is just to the aperture scale on aperture rule 64.Described black box 63 includes airtight and watertight padding 631, airtight and watertight padding gland 632 and pressing plate 633；Airtight and watertight padding gland 632 is pressed in airtight and watertight padding 631 by described pressing plate 633, and the junction of valve rod 3 and bonnet, 4 is located in described airtight and watertight padding 631.Described airtight and watertight padding uses the tetrafluoroethylene-perfluoro i.e. PFA of alkoxy vinyl ethers copolymer to constitute.
In practice, its work process is as follows:
Staff starts execution cylinder 61 and does upper and lower Direct Travel and move, and performs the outfan band ovable valve stem 3 of cylinder 61 and makees to synchronize upper and lower straight with spool 2 and become motion, it is achieved the automatization's regulation to spool 2 so that 2 dozens of ON/OFF of spool block up valve body 1.During, by the scale value on the aperture rule 64 pointed by the needle point of observation aperture pointer 65, it is achieved the accurate control to valve opening.
The above; being only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, any those skilled in the art is in technical scope disclosed by the invention; the change that can readily occur in or replacement, all should contain within protection scope of the present invention.
