Abstract
A valve with double stages of seal device is composed of valve body, connection unit, spring and flow guide unit. It is featured as setting the first seal device at inlet section of valve body and the second seal device at outlet section of valve body, connecting valve clack of the first seal device to valve clack of the second seal device by connection unit. The said valve can not only be used on pressure control, flow rate control and flow direction control but also can be used on water level control, temperature control, multiloop control, electromagnetic-automatic control, etc.
Description
Technical field:
The present invention relates to a kind of valve, particularly relate to the valve that adopts the twin-stage sealing.
Background technique:
Existing valve, owing to adopt the single-stage seal arrangement, the pressure that there is and many defectives such as the adjustable extent of flow is little, operation stability is poor, noise is big, water hammer is big, flow resistance is big entirely, negotiability is low, changeable is few, versatility is poor, using scope is little.
Summary of the invention:
Technical problem to be solved by this invention provides and a kind ofly can effectively overcome above-mentioned defective, the valve of sealing arrangement in two stages that sealability is reliable, water hammer is little, fluid resistance is little.The technical solution adopted for the present invention to solve the technical problems is, a kind of valve of sealing arrangement in two stages, mainly form by valve body, connection set, spring and flow guide device, its characteristics are: first seal arrangement is arranged at the inducer of valve body, is made up of the flap that is fixed in the valve seat on the valve body and be arranged in the valve body fixed cover; Second seal arrangement is arranged at the outlet section of valve body, is made up of the valve seat that is arranged at the flap in the valve body and be fixed on the valve body; Connect with connection set between the flap of the flap of first seal arrangement and second seal arrangement.Owing to adopt such scheme, be not difficult to draw the present invention and have following beneficial effect, the present invention is rational in infrastructure, be skillfully constructed, because there are two seal arrangements of lontitudinal series in this valve, can be as required, realize different keying effects, and realize the function of required valve according to the function of flow guide device; When being used for pressure and flow control, can realize two-stage decompression and double reduction simultaneously, make the adjustable scope of pressure and flow enlarge than the double progression of the valve of existing single-stage seal arrangement ground; In with the progression scope, the valve of the existing single-stage seal arrangement of velocity ratio that the MEDIA FLOW that feasible quilt is regulated and control is crossed seal arrangement is little, reduced probability that water cavity takes place and to the possibility of valve body cavitation erosion, noise and vibration have been reduced, operate steadily, and guaranteed the working strength and the working life of valve body; Sealing arrangement in two stages is subjected to rubbish and damages the likelihood ratio single-stage seal arrangement influence and to cause the two-stage sealing surface to leak the simultaneously probability that leaks little a lot, so its sealing reliability is very high; When being used for the occasion of check function, sealing arrangement in two stages quickens to close in the closed procedure simultaneously, and pressure reduction is more half as large than single-stage seal arrangement before and after the sealing surface, thereby water hammer is little, when standard-sized sheet, is assigned in smooth runner and rational sealing arrangement in two stages, and fluid resistance is very little; Except applying to pressure control, flow control, flow direction control, the novel valve of sealing arrangement in two stages can apply to also that water level control, temperature control, electromagnetism are controlled automatically, multiloop control, the Balance Control of water system, fire-fighting is reported to the police automatically and system between occasion such as antifouling partition control, have the adjustable scope of pressure and flow greatly, operate steadily, noise is low, reliability is high, full flow resistance is little, negotiability is big, water hammer is little, changeable is many, using scope is wide characteristics; After being assigned in various forms of flow guide devices, can be used as reduction valve, Decompression valves, modulating valve, thermostat valve, multifunctional non-return valve, flow control valve, fluid level control valve, solenoid electric valve, level pressure cut-off valve, automatic balancing valve, antifouling isolating valve, wet alarm valve, multiloop pressure, flow, flow to multi-functional occasion such as modulating valve and use, reliable performance, of many uses, the tool promotional value.
Description of drawings:
Below in conjunction with drawings and Examples the present invention is described in further detail.
Accompanying drawing is a structural representation of the present invention.
Embodiment:
Referring to accompanying drawing, the present invention is made up of valve body 1, first seal arrangement 2, second seal arrangement 3, connection set 4, spring 5 and flow guide device 6, wherein valve body 1 is made up of housing 11, vertical gusset 12, fixed cover 13, be connected with vertical gusset 12 between housing 11 and the fixed cover 13, and form the ring-type center-aisle; First seal arrangement 2 is arranged at the inducer of valve body 1, is made up of the flap 22 that is fixed in the valve seat 21 on the valve body and be arranged in the valve body fixed cover 13; Second seal arrangement 3 is arranged at the outlet section of valve body 1, forms by being arranged at flap 31 in the valve body and the valve seat 32 that is fixed on the valve body, and valve flowing channel is divided into inducer, intermediate section and outlet section; Connect with connection set 4 between the flap 22 of first seal arrangement and the flap 31 of second seal arrangement, between the flap 22 of first seal arrangement and valve body fixed cover 13, form control chamber, and spring 5 is set is used for flap and resets, flow guide device 6 links to each other with the inner chamber of valve body.
