Abstract
The utility model relates to a valve, in particular to a quick change type single-seat control valve. A valve core, a seat seal ring, a valve seat, a valve sleeve, a cover seal ring and a valve cover are arranged on a valve body, wherein the valve core is sheathed in the valve sleeve, the valve cover and the valve body are tightened, and the valve seat is a quick change type valve seat, is installed in a cavity of the valve body and is fixed through the valve sleeve; and the head end of the valve core is squeezed into the valve seat, the upper end of the valve core is fixedly connected with a valve rod, a packing and a lining ring are arranged on the valve rod, and the upper end of the valve rod is connected with a driving device. The valve seat replacement problem of the traditional single-seat valve is thoroughly solved, so that no special tool is required during replacement and maintenance, the quick change type single-seat control valve has the advantages of convenience, reliability, long service life and the like, and the requirements of energy saving and consumption reduction are truly realized.
Description
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of quick replacable type single-seat adjusting valve.
Background technique
In industries such as oil, chemical industry, food, light industrys, its valve seat of present single-seat adjusting valve all adopts thin walled structures, and screw thread is screwed into valve body; Must adopt the special tool loading, unloading; And intensity difference is yielding, can't dismantle after particularly long-term the use at all, must change complete machine; Can't realize changing the requirement of internals, field maintenance, highlight day by day with energy-saving and cost-reducing contradiction.
Summary of the invention
The utility model provides a kind of quick replacable type single-seat adjusting valve, adopts top guiding type structure, and it is streamlined that valve flowing channel is S; Valve seat adopts high tenacity not have worm structure, directly puts into the valve body lumen, with valve pocket location and fixing; Strengthened the intensity of valve seat, improved the leakage class of valve, be not threaded because of valve body has with valve base chamber; So need not the special tool loading, unloading, make valve seat replacing, install more quick and conveniently, reliability is higher.Valve seat is provided with upper and lower double-sealing face in addition, after the long-term use of valve, when last sealing surface damages, only need take valve apart, with the upset of valve seat above and below, can continue to use.A new generation's quick replacable type single-seat adjusting valve has thoroughly solved the valve seat of present single-seat valve and has changed problem, makes replacings, maintenance need not special tool, has advantages such as convenient and reliable, long service life, and has really realized the requirement of energy-saving consumption-reducing.
In order to solve the problems of the technologies described above, the utility model is able to solve through following technical proposals:
The quick replacable type single-seat adjusting valve is provided with spool, seat seal ring, valve seat, valve pocket, lid seal ring and valve gap in valve body inner bore, and spool is inserted in the valve pocket; Valve gap and valve body tighten up, and valve seat is the quick replacable type valve seat, are fit in the valve body lumen; Valve seat is fixed through valve pocket, and the valve core head end plug is gone in the valve seat, and the spool upper end is fixedly connected with valve rod; Valve rod is provided with filler and lining ring, and the valve rod upper end is connected with drive unit.
As preferably, it is linear that valve flowing channel is bend flow, and the spool head end is a plunger shape.
As preferably, drive unit is a pneumatic diaphragn actuating mechanism.
As preferably, filler has three layers, is last filler, middle filler and following filler from top to bottom.
As preferably, there is stud to fix on the valve gap.
The utlity model has following beneficial effect:
1. adopt top guiding type structure, it is streamlined that valve flowing channel is S, and valve seat adopts high tenacity not have worm structure; Directly put into the valve body lumen,, strengthened the intensity of valve seat with valve pocket location and fixing; Improved the leakage class of valve, be not threaded, so need not the special tool loading, unloading because of valve body has with valve base chamber; Make replacing, the installation of valve seat more quick and convenient, reliability is higher.
2. valve seat is provided with upper and lower double-sealing face, after the long-term use of valve, when last sealing surface damages, only need take valve apart, with the upset of valve seat above and below, can continue to use.The quick replacable type single-seat adjusting valve of the utility model has thoroughly solved the valve seat of present single-seat valve and has changed problem, makes replacings, maintenance need not special tool, has advantages such as convenient and reliable, long service life, and has really realized the requirement of energy-saving consumption-reducing.
Description of drawings
Fig. 1 is the embodiment's of the described quick replacable type single-seat adjusting valve of the utility model a structural representation.
Embodiment
The utility model is described in further detail with embodiment below in conjunction with accompanying drawing 1.
Embodiment
The quick replacable type single-seat adjusting valve, as shown in Figure 1: be provided with spool 2, seat seal ring 3, valve seat 4, valve pocket 5, lid seal ring 7 and valve gap 8 at valve body 1 endoporus, spool 2 is inserted in the valve pocket 5; Valve gap 8 tightens up with valve body 1, and valve seat 4 is the quick replacable type valve seat, is fit in valve body 1 lumen; Valve seat 4 is fixing through valve pocket 5, and spool 2 head ends are filled in the valve seat 4, and spool 2 upper ends are fixedly connected with valve rod 6; Valve rod 6 is provided with filler 11 and lining ring 12, and valve rod 6 upper ends are connected with drive unit.Drive unit is a pneumatic diaphragn actuating mechanism.It is linear that valve body 1 runner is bend flow, and spool 2 head ends are plunger shape.Filler 11 has three layers, is last filler, middle filler and following filler from top to bottom.There is stud 10 fixing on the valve gap 8.
One end of valve rod 6 is fixedly connected with spool 2; The other end of valve rod 6 stretches out valve gap 8 through valve pocket 5; Be connected on the drive unit output shaft, and upper and lower mobile with the driving of drive unit, move thereby drive the upper and lower of spool 2; Orifice size to change between spool 2 and the valve seat 4 is big or small, thereby regulates the rate-of flow that the process valve flow goes out.
When inlet inflow valve body 1 inside of flowing medium through valve body 1, with moving on spool 2 parts, flowing medium is through the epicoele of the restriction inflow valve body 1 at valve seat 4 places, by the outlet incoming fluid pipeline of valve body 1.
In a word, the above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
