Description
Technical field
The utility model relates to outlet valve, especially a kind of outlet valve of fast energy-saving simple in structure.
Background technique
Outlet valve is widely used in the gas that fluid forms in pipeline, guarantee the safety pressure in the pipeline, and eliminates " water hammer " phenomenon.Existing clear water outlet valve generally all is the valve body that drum shape is arranged, and built-in stainless steel floating ball is established guide sleeve in the valve body, when when no pressure in the pipe air being arranged; Ball float drops on the bottom of valve body, and automatic vent is after air has been arranged; Ball float rises to the top, and exhaust valve closure stops exhaust.When air is separated out when forming air bag, the water surface is reduced to ball float when following, and little valve opening is opened, and carries out the aperture automatic vent of discontinuity.Because ball float made by stainless steel, the ball wall is thinner, during exhaust when stress is big the part yielding, high speed vibration or rotation during rising, noise is big, simultaneously, complex structure, working pressure is low, so existing outlet valve reliability is not high, using scope is little.
The model utility content
The purpose of the utility model solves the exhaust structure complicacy exactly, and is fragile, and working pressure is low, the problem that reliability is not high.
The technological scheme that the utility model adopts is: a kind of fast energy-saving outlet valve; It is characterized in that it comprises valve body, valve gap, sealing following buoyancy aid and the upper float less than water; Described valve body is a tubular cavity; The valve body internal fixation has guide rod consistent with the lumen centerline direction and the sensing gas outlet, and said buoyancy aid down is provided with the slide opening adaptive with guide rod, and following buoyancy aid placed on the guide rod through slide opening and cooperating of guide rod; The upper float bottom surface is provided with boss, and following buoyancy aid top corresponding position is provided with adaptive groove, and upper float laminates in the top of following buoyancy aid through boss and groove fit; The central axis of upper float is provided with exhaust port; The bottom of exhaust port is provided with the support block that stretches into exhaust port; Following buoyancy aid top corresponding position is provided with the convexity of supported piece, makes and leave the gap between upper float and the following buoyancy aid that the center of support block is provided with the through hole that communicates with exhaust port; The lower end of support block is cambered surface, is convenient to gas and gets into through hole; Described valve gap is connected the top of valve body, and valve gap is provided with pore, makes body cavity and atmosphere; The bottom surface of valve gap is provided with the seal ring adaptive with epiphase above the upper float, makes upper float be squeezed in and seals the valve gap pore on the seal ring.
The described center of buoyancy aid down is provided with cavity.
Described upper float is a polyethylene rubber with following floating body material.
The boss of described upper float bottom surface stretches out laterally, and inwardly stretch out the groove inwall top of following buoyancy aid, forms snap-fit.
Described convexity is a sealing gasket, is cambered surface with the lower end of support block and cooperates, and through hole is sealed.
Described guide rod is square.
The utility model beneficial effect is: upper float, down buoyancy aid makes to open wide the polyethylene rubber of shape into by spherical stainless steel, and upper float, buoyancy aid adopts hasp to connect because be rubber material down, and the upper float and the body of floating downward can freely be come off; Guide rod is square, has eliminated the rotation that produces in the buoyancy aid uphill process; Through hole exhaust fast on the support block has reduced the volume of valve body.The utility model also has following advantage: smooth exhaust during high pressure; The intake and exhaust amount is big; Good energy saving property, stable performance; The intake and exhaust time is short, and simple in structure, noise is little; Can effectively eliminate water hammer in the pipe; Reduce production costs, installation and maintenance are convenient.

Embodiment
A kind of fast energy-saving outlet valve of the utility model, like Fig. 1, shown in Figure 2, it comprises valve body 1, valve gap 9, density following buoyancy aid 3 and the upper float 6 less than water, upper float 6 is a polyethylene rubber with following buoyancy aid 3 materials in the present embodiment.Valve body 1 is a tubular cavity, and valve body 1 internal fixation has guide rod 2 consistent with the lumen centerline direction and the sensing gas outlet, and guide rod 2 is square, is vertically connected on the support that is connected with valve body 1 inwall, and can weld also can scyewed joint.Following buoyancy aid 3 is provided with the slide opening adaptive with guide rod 2, and following buoyancy aid 3 placed on the guide rod 2 through slide opening and cooperating of guide rod 2.The center of following buoyancy aid 3 is provided with cavity.
As shown in Figure 4, upper float 6 bottom surfaces are provided with boss, and following buoyancy aid 3 top corresponding positions are provided with adaptive groove, and upper float 6 laminates in the top of following buoyancy aid 3 through boss and groove fit.
As shown in Figure 3; The central axis of upper float 6 is provided with exhaust port, and the bottom of exhaust port is provided with the support block 5 that stretches into exhaust port, and following buoyancy aid 3 top corresponding positions are provided with the convexity 4 of supported piece 5; Make and leave the gap between upper float 6 and the following buoyancy aid 3; The center of support block 5 is provided with the through hole that communicates with exhaust port, and the lower end of support block 5 is cambered surface, is convenient to gas and gets into through hole.Protruding 4 is sealing gasket, is cambered surface with the lower end of support block 5 and cooperates, and through hole is sealed.
As shown in Figure 1, valve gap 9 is connected the top of valve body 1 through bolt 7, and valve gap 9 is provided with pore, makes valve body 1 inner chamber and atmosphere; The bottom surface of valve gap 9 is provided with and the adaptive seal ring 8 of epiphase above the upper float 6, makes upper float 6 be squeezed in and seals valve gap 9 pores on the seal ring 8.
As shown in Figure 4, the boss of upper float 6 bottom surfaces stretches out laterally, and inwardly stretch out the groove inwall top of following buoyancy aid 3, forms snap-fit.
Nos pressure in pipe and when air is arranged, upper float 6, support block 5, protruding 4, time buoyancy aid 3 drop on bottom the valve body, carry out automatic vent by the pore of valve gap 9.
During water inlet, upper float 6, support block 5, convexity 4, following buoyancy aid 3 are raised to the top simultaneously with buoyancy of water, seal with seal ring 8, stop exhaust.When air is separated out when forming air bag, the water surface is reduced to down buoyancy aid 3 when following, following buoyancy aid 3 disengaging upper floats 6, and open in the hole of support block 5, carries out the aperture automatic vent of discontinuity.This process has been accomplished the breathing action of fast energy-saving outlet valve.
