Abstract
The present invention provides a kind of novel cutoff valve for being easy to leak detection, including valve body, flap, valve rod, bonnet and handle, changeable colour thing is provided between the bonnet and valve body, the changeable colour thing is extended to outside the bonnet, the bonnet is externally provided with translucent cover, the translucent cover covers on the bonnet, valve body junction and changeable colour beyond the region of objective existence, and filler is provided between the bonnet and valve rod, and the filler is respectively arranged with seal washer up and down.Beneficial effects of the present invention are：Filler is used in valve rod and valve cover chamber, filler sets seal washer respectively up and down, it is possible to reduce the friction between lower valve rod and valve body, while improve the sealing of valve rod and valve cover chamber；Changeable colour thing is used between bonnet and valve body, changeable colour thing, which runs into medium, to change colour, and depending on the medium that changeable colour thing transports according to pipeline, when seepage occurs in stop valve, related personnel can in time have found, handle, and avoid medium pollution environment.
Description
Technical field
The invention belongs to pipe control apparatus field, more particularly to a kind of novel cutoff valve for being easy to leak detection.
Background technology
Stop valve refers to closure member（Flap）The valve moved along valve seat center line, flap is for linear motion along the center line of valve seat, and due to the valve rod of such valve, to be turned on and off stroke relatively short, and has very reliable cutting function, and by
In the change of valve seat port and the stroke direct proportionality of flap, it is very suitable for the regulation to flow, therefore, such shutoff valve that dams is highly suitable as cutting off or the use that adjusts and throttle.Stop valve is once in opening, just there is no contact between its valve seat and valve clack sealing surface, when it is closed, with very reliable cutoff action, thus its sealing surface mechanical wear is smaller, because the valve seat and flap of most of stop valve are easier to repair or change, therefore when potted component damages, whole valve need not be removed from pipeline, this is very applicable for the integral occasion of valve and pipeline welding.
Stop valve is a kind of fully switched on or the closed circuit valve of cut-out pipeline, and it is widely used, and flow of media in control piper is often used in the industries such as oil, chemical industry.For existing stop valve when being sealed to filler, general that one layer of follower is only capped on filler, its sealing is not high, after a period of time has been used, the situation of seepage easily occurs.For transport acidic or the pipeline of alkaline medium, even a little seepage also easily causes larger pollution to environment, and slight seepage is not easy to observe.
The content of the invention
In order to solve the above-mentioned technical problem, the present invention provides a kind of novel cutoff valve for being easy to leak detection, including valve body, flap, valve rod, bonnet and handle, valve seat is provided with the valve body, the flap is located on valve seat, the bonnet is secured by bolts on the valve body, the valve rod runs through the bonnet and valve body, its lower end is connected with the flap, upper end is connected with the handle, it is characterized in that, changeable colour thing is provided between the bonnet and valve body, the changeable colour thing is extended to outside the bonnet, the bonnet is externally provided with translucent cover, the translucent cover covers on the bonnet, valve body junction and changeable colour beyond the region of objective existence, filler is provided between the bonnet and valve rod, the filler is respectively arranged with seal washer up and down.
A circle groove is provided with outside the valve body, bonnet, the translucent cover upper and lower ends are connected in the groove respectively.
The changeable colour thing is PH test paper.
Beneficial effects of the present invention are：Filler is used in valve rod and valve cover chamber, filler sets seal washer respectively up and down, it is possible to reduce the friction between lower valve rod and valve body, reduce abrasion, while improve the sealing of valve rod and valve cover chamber；Changeable colour thing is used between bonnet and valve body, and cover bonnet, valve body junction and changeable colour thing with translucent cover, changeable colour thing, which runs into medium, to change colour, depending on the medium that changeable colour thing transports according to pipeline, when there is seepage in stop valve, related personnel can in time have found, handle, and avoid medium pollution environment.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
The present invention is described in more detail below with reference to accompanying drawings, which show the preferred embodiments of the present invention, it should be appreciated that those skilled in the art can change invention described herein and still realize the advantageous effects of the present invention.Therefore, description below is appreciated that for the widely known of those skilled in the art, and is not intended as limitation of the present invention.
In figure, 1, valve body；2nd, flap；3rd, valve rod；4th, bonnet；5th, handle；6th, changeable colour thing；7th, translucent cover；8th, filler；9th, seal washer.
As shown in Figure 1, valve seat is provided with the valve body 1, the flap 2 is located on valve seat, the bonnet 4 is secured by bolts on the valve body 1, the valve rod 3 runs through the bonnet 4 and valve body 1, its lower end is connected with the flap 2, upper end is connected with the handle 5, changeable colour thing 6 is provided between the bonnet 4 and valve body 1, the changeable colour thing 6 is extended to outside the bonnet 4, the bonnet 4 is externally provided with translucent cover 7, the translucent cover 7 covers on the bonnet 4, outside the junction of valve body 1 and changeable colour thing 6, filler 8 is provided between the bonnet 4 and valve rod 3, the filler is respectively arranged with seal washer 9 about 8.A circle groove is provided with outside the valve body 1, bonnet 4, the upper and lower ends of translucent cover 7 are connected in the groove respectively.If pipeline transportation medium is acid or akaline liquid, changeable colour thing 9 can use PH test paper.
The present invention is described in detail above by embodiment, but the content is only presently preferred embodiments of the present invention, it is impossible to be considered as the practical range for limiting the present invention.Any changes and modifications in accordance with the scope of the present application, all should still it belong within the patent covering scope of the present invention.
