Abstract
The invention discloses a long-life water valve, which comprises a valve body, wherein the bottom of the valve body is provided with a bottom cover; a valve core is arranged in the valve body; a switch handle is arranged on the valve core; the valve core adopts a beaker flask valve core and is matched with the valve body; the valve core is provided with a pressure cavity; the wall of the valve core is provided with a discharge through hole passing through the valve core; the wall of the valve core is provided with a pressure cylinder water injection opening; the switch handle is arranged at asmall head end of the valve core; and a low-pressure compensation spring is arranged between the switch handle and the valve body. The long-life water valve adopts the structure of the beaker flask valve core so as to ensure that the valve core and the valve body have reliable tightness and realize abrasion self-compensation. The valve core is provided with the pressure cavity; when the valve core is closed, the pressure cavity of the valve core and a valve body bottom form a high-pressure cylinder through fluid pressure so as to keep a constant sealing state between the valve core and the valve body and realize abrasion self-compensation. A switch shaft is arranged at the small head end, and a switch end needs no additional sealing pieces due to the sealing effect of a piston; and thus, the long-life water valve not only has simple structure and low manufacturing cost, but also improves the service life.
Description
Technical field
The invention belongs to valve, be specifically related to a kind of long lifetime water valve.
Background technique
Water valve is of many uses, and is in many styles.But its structure is nothing more than four major parts such as valve body, spool, switch pair, Sealings.Except that Special valve, the working life of general valve is lower, about 1 year service time leakage phenomenon will take place.Main cause is the rapid wear general part that its component belong to low technical content, and especially spool is not durable, easily wearing and tearing.Spool wearing and tearing are from two aspects, and the one, rotatingshaft is to the wearing and tearing of Sealing, and the 2nd, Sealing self is tired and aging inevitable.Although this relevant expert was once done multiple effort, or because of complex structure, material is valuable, causes the manufacture cost height, is difficult to be widely accepted.So most of people would rather use common valve.This shows and seek a kind of not only economy but also can long-life valve be very necessary and significant.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, reliable performance, long service life, cheap long lifetime water valve.
Realize that the technological scheme that the object of the invention adopts is:
The long lifetime water valve comprises valve body, the valve body bottom is provided with bottom, be provided with spool in the valve body, spool is provided with switch knob, and described spool adopts beaker flask cooperate corresponding with valve body of spool, and spool is provided with pressure chamber, the spool wall is provided with the water through hole excessively that connects spool, be provided with the pressure cylinder water filling hole with the position of crossing water through-bore axis approximate vertical on the spool wall, described switch knob is located at the little head end of spool, is provided with the low-voltage compensation spring between switch knob and the valve body.
Be provided with seal ring between described valve body bottom and the valve body.
Described valve body and spool can adopt cast copper or casting spare etc.
The spool that the present invention adopts is that big tapering floats and can revolve piston valve core, has reliable sealing between the cone structure of spool and the valve body; Unsteady then realize wear-self-compensation; Suitably big tapering can prevent that then spool coupling mechanism force under high pressure conditions is excessive, and switch is not freely; Switch axle is located at little head end, has utilized the seal action of piston, so switch terminals is not wanted the additional encryption sealing, so promptly simple in structure, low cost of manufacture have improved working life again.
Spool is established pressure chamber, when closing, spool can utilize the pressure cylinder water filling hole on it in pressure chamber, to inject tap water, use hydrodynamic pressure and make and constitute high-pressure cylinder at the bottom of spool pressure chamber and the valve body, make spool upwards the top lift and valve body between keep constant sealing state, and realize wear-self-compensation.So, can reduce wear simultaneously because wall of cup has the microcosmic resiliently deformable and has better sealing.Its connection band meaning is weight reduction, lowers whole manufacture difficulty and precision.And under the high pressure conditions, performance is reliable more; Long more its superiority that shows more used the spool wearing and tearing always and lost till the self compensation service time.This moment, valve body can use as usual as long as change spool.
Between switch knob and valve body, establish the low-voltage compensation spring, to guarantee stress that spool still keeps up and good sealing effect under low-pressure state.Spring is located to utilize herein and can makes the finger-tight spool spring be subjected to excellent protection again.
Description of drawings
Fig. 1 is structural representation of the present invention (for closed condition).
Fig. 2 is the open mode schematic representation of Fig. 1.
Among the figure: 1, valve body, 2, bottom, 3, seal ring, 4., spool, 5, the pressure chamber water filling hole, 6,7, cross the water through hole, 8, pressure chamber, 9, switch knob, 10, connect the boomerang nail, 11, the low-voltage compensation spring.
Embodiment
See Fig. 1, the long lifetime water valve comprises valve body 1, valve body 1 bottom is provided with bottom 2, be provided with seal ring 3 between bottom 2 and the valve body 1, be provided with in the valve body 1 that beaker flask spool 4 is corresponding with valve body to be cooperated, switch handle 9 usefulness connect boomerang nail 10 and are fixed on the switch axle of spool 4, spool 4 is provided with pressure chamber 8, the spool wall is provided with the water through hole 6,7 excessively that connects spool 4, on the spool wall, be provided with pressure chamber water filling hole 5 with the position of crossing water through-bore axis approximate vertical, switch knob 9 is located at the little head end of spool 4, is provided with low-voltage compensation spring 11 between switch knob 9 and valve body 1.Valve body and spool can adopt materials such as cast copper or casting spare.
Working condition and principle:
When 1, water valve cut out, the pressure chamber of beaker flask spool 48 constituted high-pressure cylinders with valve body bottom 2, and fluid enters high-pressure cylinder through pressure chamber water filling hole 5, thereby formed high pressure to the election of spool 4 with to the tension force of spool wall, realized the excellent sealing with valve body.
When 2, water valve is performed fighting, as shown in Figure 2, have an effect, can keep the sealing of spool and valve body,, also can not occur leaking according to law of minimum resistance, herein so need not the additional seal device even there is microgap in junction plane this moment by low-voltage compensation spring 11.
Claims (2)
1. long lifetime water valve, comprise valve body, the valve body bottom is provided with bottom, is provided with spool in the valve body, and spool is provided with switch knob, it is characterized in that described spool adopts beaker flask cooperate corresponding with valve body of spool, spool is provided with pressure chamber, and the spool wall is provided with the water through hole excessively that connects spool, is provided with the pressure cylinder water filling hole with the position of crossing water through-bore axis approximate vertical on the spool wall, described switch knob is located at the little head end of spool, is provided with the low-voltage compensation spring between switch knob and the valve body.
