Abstract
A kind of annular float valve core type drain valve, is made up of valve body, valve seat, downspout, annular float spool；It is characterized in that: valve seat upper end is connected with valve body upper end, downspout upper end is connected with valve seat upper end, and annular float spool is arranged between valve seat and downspout.Present configuration is simple, dependable performance, altogether only have four parts, manufacture assembling and working service low cost, annular float spool acts the buoyancy and gravity closed, and is not affected by magnitude of back pressure, even if discharge outlet sectional area is the biggest, also will not be excessive and locked because the pressure reduction imported and exported, thus have that displacement is big, continuous drainage, a draining not steam discharge, use failure rate is low, long advantage in service life.
Description
Technical field
The present invention relates to a kind of drain valve, particularly relate to a kind of annular float valve core type drain valve.
Background technology
Whether normal the action of Automatic steam trap Trap is, affects conveying and the service efficiency of steam to a great extent.For ensureing to steam
Condensation water in the operating mode that vapour is the best, pipeline and gas utilization unit should be discharged it outside system by drain valve in time.
The most conventional drain valve has mechanical type, heat static force type, heat power type three major types type.Mechanical type drain valve: also referred to as float-type,
Utilize the density contrast condensing water with steam, change by condensing water liquid level, make float drive flap to be turned on and off, reach resistance
Vapour draining purpose.The degree of supercooling of mechanical type drain valve is little, is not affected by operating pressure and variations in temperature, has water i.e. to arrange, makes
Not water in firing equipment, reaches optimal heat exchange efficiency.General maximum rate of back pressure is 80%, and work quality is high, is to produce work
One of optimal drain valve of skill firing equipment.Heat static force type drain valve: this kind of drain valve is to utilize steam and condense the temperature of water
Difference causes the deformation of temperature-sensing element or expands band movable valve plug opening/shutting valve.The degree of supercooling of heat static force type drain valve is bigger, its energy
Utilizing a part of sensible heat condensed in water, have condensed water in high temperature before valve all the time, leak without steam, energy-saving effect is notable.It is
On the less demanding small-sized firing equipment of jet chimney, heat traced pipeline, small-sized firing equipment, heating equipment equitemperature, manage most
The drain valve thought.Heat power type steam trap: this kind of drain valve according to Transformation Principle, by steam and condense water by time flow velocity
With the different thermodynamic principles of change in volume, make flap produce different pressure reduction up and down, drive flap controlled valve.Owing to heat is moved
The operation power of power type drain valve derives from steam, so waste of steam is bigger.Simple in construction, resistance to water attack, have noise,
Frequently, service life is short in flap work.
Conventional mechanical type drain valve has: free floating ball type, freely half float-ball type, lever float ball type, reverse bucket type etc..This
The maximum drawback of a little Automatic steam trap Traps is exactly that rate of back pressure is low, and displacement is little, some can not continuous drainage, some parts how therefore
Barrier rate is high and manufactures assembling and working service cost height, is difficult to adapt to the needs that current high-power big displacement requires.
Summary of the invention
It is an object of the invention to solve above-mentioned contradictory problems for prior art, it is proposed that a kind of annular float spool
Formula drain valve, belongs to mechanical type drain valve, is made up of valve body, valve seat, downspout, annular float spool.
The present invention is achieved in that
A kind of annular float valve core type drain valve, is made up of valve body, valve seat, downspout, annular float spool；It is special
Levying and be: valve seat upper end is connected with valve body upper end, downspout upper end is connected with valve seat upper end, and annular float spool is arranged on
Between valve seat and downspout.
Described a kind of annular float valve core type drain valve, is characterized in that: valve seat is a blind pipe structure, lower half tube wall
Circumference has draining sieve aperture.
Described a kind of annular float valve core type drain valve, is characterized in that: downspout lower half circumference has draining sieve aperture,
Top circumference has a pair balance pipe.
Described a kind of annular float valve core type drain valve, is characterized in that: annular float spool is a cavity ring body.
Advantages of the present invention:
Present configuration is simple, dependable performance, the most only four parts, manufactures assembling and working service low cost,
Annular float spool acts the buoyancy and gravity closed, and is not affected by magnitude of back pressure, even if discharge outlet sectional area is big again, also
Will not be excessive and locked because the pressure reduction imported and exported, thus have that displacement is big, continuous drainage, a draining not steam discharge, make
By failure rate is low, long advantage in service life.
Accompanying drawing illustrates:
Fig. 1 is the sectional view of the present invention.
Figure 1 is valve body, 2 be valve seat, 3 be downspout, 4 for annular float spool.
Detailed description of the invention
A kind of annular float valve core type drain valve, by valve body 1, valve seat 2, downspout 3, annular float spool 4 groups
Become；It is characterized in that: valve seat 2 upper end is connected with valve body 1 upper end, downspout 3 upper end is connected with valve seat 2 upper end, ring
Shape float spool 4 is arranged between valve seat 2 and downspout 3.
Described a kind of annular float valve core type drain valve, is characterized in that: valve seat 2 is a blind pipe structure, and lower half is managed
Wall circumference has draining sieve aperture.
Described a kind of annular float valve core type drain valve, is characterized in that: downspout 3 lower half circumference has draining sieve
Hole, top circumference has a pair balance pipe.
Described a kind of annular float valve core type drain valve, is characterized in that: annular float spool 4 is a hollow circular
Body.
