Abstract
An improved drainer is especially a device which is provided with an overlapping double-lever type structure, the whole mechanism is totally connected in a center frame to realize the whole disassembly and assembly, and a filtering net with big area and a fabricated valve seat are arranged in the drainer to increase the working pressure of the drainer, lower the volume and make the work of the drainer reliable.
Description
The utility model relates to the condensed water steam trap that a kind of improved vapour system is used, and particularly has the eclipsed form dual lever mechanism, and the unlatching buoyancy of valve is amplified, thereby the operating pressure of valve is improved and physical dimension reduces.Again owing to adopted intermediate support supporting lever mechanism and ball float, make it make and the housing of mechanism's integral body can being packed into during maintenance in or shift out outside the housing.
Existing steam trap adopts ball float smooth surface and the direct rigidity touch controls of draining valve port upper surface draining more, because the poorly sealed steam trap that causes of rigid surface leaks vapour.
Task of the present utility model be to provide a kind of reliable operation, volume little, simple in structure, make overlapping double lever type steam trap easy to maintenance.
Task of the present utility model is achieved in that overlapping double lever type steam trap is made up of shell, intermediate support, leverage, top cover etc.Do a description below in detail:
1. the course of work: when steam entered system, original cold air was at first discharged from the air bleeding valve G that covers end by the screen pack on the intermediate support, and along with the temperature that enters of condensed water and steam raises, bimetal leaf is bent upwards closes air bleeding valve automatically; Along with the increase ball float of condensed water is floated by water, U type ring pulling double lever one end by the ball lower end moves upward, and the draining cone valve of bottom is opened, and condensed water is discharged from from the B mouth.Along with water level descends, ball float falls to promoting double lever with drain shut valve, when preventing that the draining cone valve from opening and drain valve seat laterally break away from, designed lead in its lower end.
2. dual lever mechanism: overall structure is made up of intermediate support, ball float, double lever, draining valve and lever steady pin etc., its architectural feature is: U type suspension ring are welded in the ball float lower end, U font suspension ring link to each other with upper lever one end, its other end is fixed on the intermediate support by bearing pin, one end of following lever is connected by bearing pin with the upper lever interstitial hole, the other end is connected by bearing pin with intermediate support, and the lever interstitial hole is connected by bearing pin with draining cone valve upper end.There is screen pack in the outer garden of intermediate support first half air port by fixation with steel wire.
3. drawing explanation:
Fig. 1 is overlapping lever steam trap assembling full sectional view, ratio 1: 2.
Fig. 2 is an A-A cutaway view shown in Figure 1, ratio 1: 2.
Below in conjunction with accompanying drawing the utility model is described in detail:
Fig. 1 is overlapping lever steam trap assembling full sectional view, and its structure is as follows:
(1) lever, (4) drain valve seat, (5) draining cone valve, (6) ball float, (7) bearing pin, (8) upper lever, (9) bearing pin, (10) screw, (11) pad, (12) steel wire, (13) intermediate support, (14) screw, (15) screen pack, (16) bimetal leaf, (17) exhaust poppet valve, (18) delivery valve seat, (19) U type suspension ring under shell, (2) bearing pin, (3).
Fig. 2 is that its structure of A-A cutaway view of Fig. 1 is as follows:
(1) lever, (5) draining cone valve, (7) bearing pin, (8) upper lever, (9) bearing pin, (13) intermediate support, (19) U type suspension ring under shell, (2) bearing pin, (3).
Claims (2)
1, a kind ofly supports by intermediate support, the double lever that eclipsed form is arranged, the ball float suspension ring have lead draining cone valve, and filter window and screen pack all are connected in one, can realize the overlapping double lever type steam trap of demolition, installation overall separation, it is characterized in that: U type suspension ring and ball float weldering are one, and two levers link to each other by bearing pin with center bearing bracket respectively up and down, and the draining cone valve links to each other by bearing pin with following lever, valve seat adopts fabricated construction, and center bearing bracket upper window cylindrical is fixed with screen pack.
2, overlapping double lever type steam trap as claimed in claim 1, its characteristics are that draining cone valve lower end has guide frame.
