Abstract
The utility model discloses a direct-discharge draining valve, which mainly solves the problems of draining valves, such as poor drainage and evacuation performance, absence of filter function, high possibility of blocking, requirement for extra pumping equipment, complicated system, inconvenience for maintenance, frequent shut-down operation, and adverse effect on heat exchange efficiency. The direct-discharge draining valve is characterized in that an air inlet is formed in one end of the valve body; an air outlet is formed in the other end of the valve body; a nozzle is formed in the bottom of the valve body; a bypass hole communicated with the air inlet is formed in the sidewall of the valve body; a valve core part matched with the bypass hole is arranged in the bypass hole, and includes a filter mesh cover and a protection cover; and a pinhole drainage filter element is detachably inserted in the protection cover. The direct-discharge draining valve provided by the utility model can filter stream in a double-layered mode and can clean impurities by adding the filter structure in the valve core part; the filter element in the valve core part is replaceable and can be changed to different pinhole drainage filter elements according to different processes so as to promote water drainage and improve heat conversion efficiency; and the direct-discharge draining valve needs no extra manual or automatic exhaust device, so that the system is simple and convenient to maintain.
Description
Technical field
The present invention relates to a kind of drain valve, is more specifically a kind of direct-exhausting type drain valve.
Background technique
Drain valve kind in actual production process is a lot, and the drain valve of conventional float-type, when condensing current valve pocket to a certain extent, due to floating function bucket floating, is started working.While reducing buoyancy, throttle down.In order to increase the discharge capacity of Open bucket steam trap, must increase valve area, therefore must increase weight and the volume of drum, to increase the moment of unlatching and the valve of holding one's breath.Thereby the emptying poor-performing of the draining of this drain valve, for accelerating the discharge of water of condensation, usually needing additionally increases venting gas appliance manually or automatically, causes system complex, maintenance and repair inconvenience.Be subject to the structural limitations of valve, this type of valve generally lacks filtrating equipment simultaneously, and in water, impurity easily stops up or damage spool and valve seat.Due to impeded drainage, cause equipment thermal conversion efficiency low in addition, temperature does not reach the requirement of production, usually needs to shut down system is safeguarded, because the shutdown that blocked drain causes waits for that number of times is more.
Summary of the invention
The present invention solves the existing technical problem of above-mentioned existing drain valve, and a kind of direct-exhausting type drain valve is provided.
The technical solution used in the present invention is; construct a kind of direct-exhausting type drain valve: comprise valve body; described valve body one end is provided with suction port, the other end is provided with air outlet; described valve body bottom is provided with spout; the sidewall of described valve body is provided with the by-pass hole communicating with described suction port; in described by-pass hole, be provided with the spool portion of mating with it; described spool portion comprises the semicircle cylindricality filtering screen of the upper end open being fixed together and the semicircle cylindricality safety cover of lower ending opening, dismountable thin filter core of pin hole that is inserted with also in described safety cover.
Described filtering screen and safety cover are made by aluminum alloy material, for netted, and be close together and be inserted in by-pass hole, and in suction port, water and steam, after the double medium filtration of filtering screen and safety cover, enters pin hole and dredges filter core, stop and stop up filter core and wearing and tearing valve seat.
Described pin hole is dredged filter core profile and safety cover inwall matches, can be according to the flow of different process situation, and change different pin holes and dredge filter core, to accelerate the discharge of water of condensation.
The opening of described valve body by-pass hole is also provided with the bolt of fixed spool, for standing valve core, when needing replacing or clearing valve core, turns on bolt, can complete the cleaning of replacing or impurity.
Described spout is rectangular, and from then on water of condensation flows out in hole, and spout is threaded connection outward and is connected with waste pipe.
Direct-exhausting type drain valve provided by the utility model, has following beneficial effect: spool portion increases filtration, realizes double medium filtration to steam and the cleaning of impurity; Spool portion replaceable filter element, can change different pin holes according to technique various flows and dredge filter core, accelerates the discharge of water, improves thermal conversion efficiency; Without additionally increasing venting gas appliance manually or automatically, system is simple, easy to maintenance.
