Description

Quick action exhaust valve

The quick-action outlet valve belongs to building water heating system technical field.

In the hot-water heating pipe-line system in building, for guaranteeing the unimpeded of water cycle, need get rid of gas in the pipeline with outlet valve, present domestic like product, no matter be lever or spring structure, all exist greatly, close insensitive such as volume, complex process, defective such as easy water clock and maintenance trouble when hanging down hydraulic pressure.

The purpose of this utility model provides a kind of highly sensitive, and sealing configuration is reasonable, leakage-proof, the quick-action outlet valve of being convenient to keep in repair.

The utility model is achieved in that the quick-action outlet valve is made up of valve body spare, workpiece, control piece, auxiliary member, valve gap, bonnet, valve body, check valve body and seal ring are arranged in the valve body spare, valve rod, exhaust rubber cushion, compressing tablet and stage clip are arranged in the workpiece, float is arranged in the control piece; Become whole with scyewed joint between the valve body spare, workpiece is with laterally, and control piece and auxiliary member are vertically to be loaded on the valve, and the valve rod in the workpiece divides big end and thin end, its big end end face is a sphere, is pressed on exhaust rubber cushion the inner at the big end sphere of stage clip effect lower valve rod and seals central needle hole; Have in the auxiliary member that valve is led, stage clip and seal ring, have the arm of force of being subjected to and seal groove on the valve guide structure, be subjected to the arm of force to be arranged in the cavity of resorption of valve, seal ring is exposed to outside the valve, is being subjected to advancing of the arm of force and valve that stage clip is housed between the hole, seal groove is equipped with seal ring.When not having gas promptly to be full of water in the outlet valve, the thin end of float in the control piece and the valve rod in the workpiece disengages, and valve rod only is subjected to the stage clip effect and is in sealing state; When in the valve gas being arranged, float in the control piece falls to depressing valve rod simultaneously carefully to be held, thus the sealing state of destruction work spare, in the valve gas just the central needle hole from the exhaust rubber cushion discharge.

The structure that it is sphere that the utility model adopts the big end end face of valve rod can improve sealing effect, and the valve in the auxiliary member is led and also greatly made things convenient for maintenance work in addition.

Concrete structure of the present utility model and embodiment are provided by the following drawings, literal:

Fig. 1 is a quick-action outlet valve assembling schematic representation;

Fig. 2 is the side channel position view on the float;

Fig. 3 is that valve is led the sectional shape schematic representation.

The quick-action outlet valve is made up of valve body spare, workpiece, control piece and auxiliary member, and valve gap 1, bonnet 2, valve body 4, check valve body 6 and seal ring 12,13 are arranged in the valve body spare.Valve rod 3, exhaust rubber cushion 8, stage clip 10, compressing tablet 9 are arranged in the workpiece, and wherein valve rod 3 has big end and thin end, and holding the exterior edge face greatly is sphere 25, and there is pin hole 30 at exhaust rubber cushion 8 centers, and float 5 is arranged in the control piece, has in the auxiliary member that valve leads 7, stage clip 11 and a seal ring 14; Respectively with scyewed joint, and be formed with side chamber 15, epicoele 16, cavity of resorption 17 between the valve body spare, atmosphere and side chamber, cavity of resorption and outside between the pipeline respectively by the exhaust port on the valve body spare 28, side opening 18, down hole 26, enter hole 27 and be connected; Workpiece is with in the side chamber 15 and epicoele 16 that laterally are loaded on valve, wherein the big end of valve rod 3 and exhaust rubber cushion 8, stage clip 10, compressing tablet 9 are positioned at the side chamber, and the thin end of valve rod stretches in the epicoele, stage clip 10 is loaded between big end of valve rod and the side opening 18, during sealing state, be that float floats when not contacting with valve rod, spring pressure is outwards sealed pin hole 30 with the inner that the big end sphere of valve rod is pressed on exhaust rubber cushion 8; Float 5 in the control piece vertically is arranged in epicoele 16, float can be according to medium effect in the chamber, fluctuate rapidly flexibly, the structure of float is divided into upper and lower two-part, the bottom is a solid cylinder, two symmetrical side channel 19 and kerves 20 that are positioned at the bottom surface that are positioned at the axis both sides are arranged on the cylindrical body, side channel is connected with kerve, buoy upper has translot 21, translot one end top seal forms crossbeam 22, the thin end of valve rod that stretches into epicoele is in the below of crossbeam all the time and controlled by float, and the groove of translot 21 is to perpendicular with the line of centres of two side channels 19; Valve in the auxiliary member is led has the arm of force of being subjected to 23 and seal groove 24 on 7 structures, wherein be subjected to the arm of force 23 and stage clip 11 to be arranged in cavity of resorption 17, seal groove 24 stretches out and is exposed to outside the valve from entering hole 27, in the cavity of resorption, stage clip is loaded on and is subjected to the arm of force and advances between the hole 27, valve is led be subjected to all the time spring pressure upwards, valve lead on 7 with seal groove 24 about the round platform rank be that the two-part sectional shape up and down of boundary is flat-shaped, be subjected to the arm of force 23 quantity and layout and its to should be two and symmetrical mutually.

Float in the utility model adopts the integral molded plastic structure, and weight is light and handy, and its side channel is connected with kerve and makes water, air-flow unimpeded, guarantees that float is swift in motion.Because gas is runner with the bottom side groove mainly,, prolong the valve rod life-span so buoy upper translot groove can reduce the impact of gas to valve rod to avoiding two side channels in epicoele; Therefore the radius of curvature of each point is identical on the sphere in addition, is valve rod axis and pin hole 30 axis not during conllinear when hydraulic pressure instability valve in makes valve rod that small change in location be arranged, and needs only the spheric curvature center on the pin hole axis, and then sphere still can normally be implemented to seal; Also have at the inboard center of bonnet plug 29 is arranged, plug does not block pin hole when the outlet valve proper functioning, in case outlet valve damages when leaking, just tighten bonnet and block pin hole by plug, stop and metalling run out, during maintenance, unload valve body 4, originally the valve that was in normally open is led under the stage clip effect and is moved up, and seal ring is just sealed into hole 27.
