Abstract
A combined cutt off-filter valve integrating the plunger valve with filter is composed of valve body, valve cover, valve rod, plunger, and cylindrical net filter installed in the filter cavity of valve body. Its advantages are both cut-off and filter functions, and long service life.
Description
Technical field
The invention belongs to valve field, relate in particular to a kind of with plunger (ending) valve and filter make one by filtering combination brake switch and proporting.
Background technique
Plunger valve in the known technology, stop valve occasion different with the filtration device structure function and that use is also different, acts on singlely, and all is independent use.Especially at liquid (gas) body plunger valve and the stop valve that uses in the pipeline of impurity arranged, owing to impurity is arranged through regular meeting's blocking pipeline and wearing and tearing valve in the fluid, the working life of causing valve is short and often overhaul pipeline or change valve.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned plunger (ending) valve at liquid (gas) body the defective of using in the pipeline of impurity to be arranged, and provide an a kind of valve have unidirectional by and filter double effects by filtering combination brake switch and proporting.
The technical solution adopted in the present invention is: a kind of by filtering combination brake switch and proporting, the plunger that it mainly is made of valve body, valve gap, valve rod and plunger (ending) valve portion, it is characterized in that going up on the same prolongation axis in chamber in the described valve body filtering cavity is set down, the import of its valve body be communicated with by the chamber, and the outlet of valve body is communicated with filtering cavity under the valve body that the tubular filter screen is housed.And in the valve body by the axis and the valve body import of chamber and filtering cavity part with the export pipeline coupling shaft is linear has angle.
The invention has the beneficial effects as follows: have the structure and the effect of ending and filtering owing on a valve, designed, promptly reduced the manufacture cost of valve, reduced usage space and installation work-hour, prolonged the working life of valve.Improve overhaul efficiency when particularly in the liquid of impurity (gas) pipeline is arranged, using.

Embodiment
Below in conjunction with drawings and Examples foundation structure of the present invention and effect are explained as follows.
Embodiment 1:
Plunger type is by filtering combination brake switch and proporting as shown in Figure 1, it have structure identical with known technology by valve body 6, valve gap 4, the plunger valve part that valve rod 3 and plunger 5 constitute, it is characterized in that: be set in its valve body by chamber 6-1 and following filtering cavity 6-2 two-part with plunger valve, its handwheel 2 is fastening by Stem Mut 1 and valve rod 3 upper ends, valve gap 4 is encapsulated in valve body 6 upper end-hole, the cylinder type plunger 5 that its valve rod 3 passes in valve gap 4 its lower ends and the valve body is connected, last seal ring 7 in the chamber places the upper and lower port of valve body import respectively with lower seal 12, the import 13 of its valve body be communicated with by the chamber, and the outlet 14 of valve body is communicated with filtering cavity under the valve body that the tubular filter screen is housed, flow to according to the best of valve body structure and connecting pipeline, make valve body end chamber and filtering cavity axis and valve body import and export pipeline coupling shaft line and form a θ＜90 ° forward angle.For regular exhaust filtering chamber fluid impurity sediments after filtering, sealing gasket 10 is housed and by the fastening filtering cavity valve gap 15 of bolt 9 at valve body filtering cavity bottom opening.Be provided with blowdown in the middle of the filtering cavity valve gap 15 and block up 8, when the impurity sediments of exhaust filtering chamber, generally only back out blowdown and block up and conveniently to discharge.The valve body import is connected with pipeline with outlet adopts flange-type to connect.
Embodiment 2:
Another kind of novel plunger-type as shown in Figure 2 is by filtering combination brake switch and proporting, and it is the improvement on known plungers formula stop valve basis.Be set in its valve body by chamber 6-1 and following filtering cavity 6-2 two-part plunger valve, the import 13 of its valve body be communicated with by the chamber, and the outlet 14 of valve body is communicated with filtering cavity under the valve body that the tubular filter screen is housed, flow to according to the best of valve body structure and connecting pipeline, make valve body end chamber and filtering cavity axis and valve body import and export pipeline coupling shaft line and form a θ＜90 ° forward angle.Be that with embodiment's 1 plunger valve different piece the filtering cavity 6-2 plunger 5-1 that is adopted in the 6-1 of chamber connected vertically has at least the compound seal of two surface of contact to be connected with lower seal elastic ring 12 on being installed on the valve seal platform, on its lower seal elastic ring 12 support ring 17 is set, screw thread in device has on the support ring 17 in the locknut 18 of side and the valve body mouthful spins, adopt thread seals to cooperate with valve gap 4 in the valve body mouthful and spin, install successively on the sealing platform of valve gap upper end hole compound on sealed soft circle 7, valve mother 19 and valve gap upper end-hole spin.The valve body import adopts flange to be connected with outlet and pipeline.
Embodiment 3:
As shown in Figure 3 be a kind of flap type by filtering combination brake switch and proporting, on the basis of embodiment 1 and 2 improvement parts, the plunger valve different piece be with filtering cavity 6-2 plunger cavity 6-1 connected vertically in adopted by flap plunger 5-2 and by sealing gasket 12 are normal structures of known technology.The valve body import adopts flange to be connected with outlet and pipeline.
Embodiment 4:
As shown in Figure 4 screw connected by filtering combination brake switch and proporting, on the basis of embodiment 1-3 improvement part, except that valve body import and outlet are to adopt the thread connecting mode with pipeline connecting mode, its plunger valve is partly identical with embodiment's 3 known plungers valve arrangements.
Valve body of the present invention can adopt cast iron, cast steel or cast copper to make, and described sealing gasket can adopt teflon, fluorine rubber to make.
Claims (5)
