Abstract
The invention relates to an adjustable water drainage valve with elastic steel ball sealing. The invention has the advantages that steel balls are matched with a spring, thus the sealing surface of the valve seat is not damaged, and the sealing property is good; the service life is long; the water exhaust temperature can be adjusted as an adjusting screw is arranged; and the function is complete.
Description
Technical field:
The present invention relates to the drain valve field, the spool of heat static force type drain valve especially, elastic steel ball sealing switch.
Background technique:
The switch spool of drain valve normally adopts taper to seal firmly at present, and poor sealing performance pushes up easily when temperature is too high and hinders sealing surface of seat, and working life is short, and the present invention just in time can solve this difficult problem.
Summary of the invention:
For solving the drain valve difficult sealing, the problem that working life is short the invention discloses the advanced adjustable water drainage valve with elastic steel ball sealing of a cover, it is highly sensitive to aim to provide a cover, good seal performance, long service life is not damaged the adjustable water drainage valve with elastic steel ball sealing of sealing surface.
The adjustable water drainage valve with elastic steel ball sealing that the present invention mainly is made up of temperature control element, valve rod, spring compressor, valve seat, seating spring, steel ball, steel ball and spring, valve body, adjusting screw, valve gap, bonnet, sealing gasket, filter screen etc., it is a kind of adjustable water drainage valve with elastic steel ball sealing, adopt steel ball to cooperate with spring, do not damage sealing surface of seat, good seal performance, long service life, band adjusting screw, the can regulate Temperature at discharging condensate, multiple functional outstanding drain valve.
When just beginning, temperature control element holds its shape, seating spring is pushed spool open, drain valve is opened, the air and the cryogenic condensation water that enter in the drain valve are discharged rapidly through valve seat, and then condensed water in high temperature enters drain valve, temperature raises in the valve, temperature control element begins temperature distortion, promotes spool and moves to the valve seat direction, and steel ball is the self-alignment close port under the promotion of steel ball and spring, when spool continues when the valve seat direction moves, spool withstands valve seat, and steel ball is pressing spring to shrink back in spool, at this moment forms double-layer seal.When condensing water temperature reduced, temperature control element was flexible according to the temperature variation regulating spool, and steel ball tightly is close to valve seat under spring pressure.The drain valve sealability is fine, and steel ball can not weigh sealing surface of seat wounded, and working life is very long, and is highly sensitive, reliable working performance.This valve is provided with adjusting screw, can regulate drain temperature as required.This valve also has the large size filter screen, prevents that drain valve from stopping up.
The great advantage of patent adjustable water drainage valve with elastic steel ball sealing of the present invention is a good seal performance, also can not weigh sealing surface of seat, long service life wounded when foreign material silt blocks valve port.
This drain valve adopts accurate cast steel valve body, and inner components all adopts the manufacturing of high-quality stainless steel material.Its selection essence, design technology advanced person, low cost of manufacture are rational in infrastructure, multiple functional high-quality drain valve, and it is hydrophobic to can be used for steam pipe system, companion heat, heating equipment, and using scope is very wide.
Description of drawings
Among Fig. 1 be: the structure internal anatomy of elastic steel ball adjustable water drainage valve
Among the figure: adjusting screw (1), valve rod (2) temperature control element (3), jump ring (4) spring compressor (5), seating spring (6), steel ball and spring (7), spool (8), steel ball (9), valve seat (10), sealing gasket (11), valve body (12), filter screen (13), sealing gasket (14), valve gap (15), bonnet (16)
Embodiment:
The present invention is further described below in conjunction with accompanying drawing and example
As shown in Figure 1: the adjustable water drainage valve with elastic steel ball sealing that the present invention mainly is made up of valve rod (2), temperature control element (3), spring compressor (5), seating spring (6), steel ball and spring (7), spool (8), steel ball (9), valve seat (10), valve body (12), filter screen (13), valve gap (15) etc.
When equipment just starts, temperature is low in the drain valve, temperature control element (3) holds its shape, seating spring (6) is pushed spool (8) open, drain valve is opened, the air and the cryogenic condensation water that enter in the drain valve are discharged rapidly through valve seat (10), and then condensed water in high temperature enters drain valve, temperature raises in the valve, temperature control element (3) beginning temperature distortion, promoting spool (8) moves to valve seat (10) direction, steel ball (9) self-alignment close port under the promotion of steel ball and spring (7), when spool (8) continues to valve seat (10) when direction moves, spool (8) withstands valve seat (10), steel ball (9) is pressing steel ball and spring (7) to shrink back in spool (8), at this moment forms double-layer seal.When condensing water temperature reduces, temperature control element is flexible according to temperature variation regulating spool (8), steel ball (9) tightly is close to valve seat (10) under steel ball and spring (7) pressure, sealability is fine, steel ball (9) can not weigh valve seat (10) sealing surface wounded, working life is very long, and is highly sensitive, reliable working performance.
