Abstract
Disclosed is a free semi-floating steam water trap, which includes a valve body, a valve cover and free semi-floating. It is characterized in that: 1.a drain nozzle is table cylindrical shape and comprises non-metal materials of high temperature resistance, anti-wearing and impact resistance; 2.the check valve that comprises a guide seat, a spring and a guiding rod is arranged at the outlet of the drain nozzle, the bottom sealing face of check valve guide rod is plane, inclined plane or arc surface. The utility model free semi-floating steam water trap not only overcomes such defects as big steam leakage, easy damage of semi-floating, easy wearing for drain nozzle and short service life, but also is easy to install and repair by not installing outer connected check valve at the outlet of drain nozzle, which reduces the cost of project and energy. Therefore; the utility model is the most ideal steam water trap so far.
Description
The utility model belongs to valve technology field, relates in particular to a kind of freedom half float ball type steam drain valve.
Existing freedom half float ball type steam drain valve mainly is made of valve body, valve gap and half ball float, be provided with admission passage and discharge channel in the valve body, in body cavity, be provided with pad, the emission tube that communicates with admission passage is housed on the pad, and discharge channel is connected with draining nozzle on being installed in valve gap and communicates with body cavity.Because all sealed members are stainless steel part, be sealed into hard sealing,, in valve body, be provided with the pad of an inclination in order to reach the better seal effect, making half ball float is to coincide with the draining nozzle under the rotation status when risen by buoyancy, plays the effect of sealing at random.But do a fatal defective like this and be exactly very quick-wearing and damaging of half ball float and draining nozzle, shortened the working life of product.The another one shortcoming of this freedom half float ball type steam drain valve is exactly because the draining action is very frequent, and the safety check performance requirement external for its water outlet end is very high, because once safety check damages, then drain valve can not proper functioning.The claimant has belonged to the most advanced structural type in " safety check " patent application (authorize, the patent No. is 982328435) that on July 6th, 1998 proposed aspect safety check, but still is difficult to satisfy the job requirement of this drain valve.
The purpose of this utility model is to overcome the various shortcomings that exist in the prior art, and a kind of stable performance is provided, long service life, freedom half float ball type steam drain valve with check function.
For achieving the above object, provide technological scheme as follows: free half float ball type steam drain valve comprises valve gap, valve body and free half ball float, be provided with admission passage and discharge channel in the valve body, in body cavity, be provided with the emission tube that communicates with admission passage, launch hole is arranged on the emission tube, discharge channel is connected with draining nozzle on being installed in valve gap and communicates with body cavity, and it is characterized in that: 1, the draining nozzle is that billiard table is cylindrical, is made by high temperature resistant, wear-resisting, impact-resistant nonmetallic material.2, in the outlet port of draining nozzle safety check is installed, this safety check is made up of guide holder, spring and guide rod, and particularly the sealing surface of guide rod bottom is plane or inclined-plane or arc surface.
Fig. 1 is the utility model structural representation.
Fig. 2 is a draining structure of nozzle schematic representation.
Fig. 3 is the structural representation of non-return valve tail rod.
Now in conjunction with the accompanying drawings the utility model is described in detail: by Fig. 1, free half float ball type steam drain valve comprises valve body (1), valve gap (2) and free half ball float (3), be provided with admission passage (4) and discharge channel (5) in the valve body (1), in the inner chamber of valve body (1), be provided with the emission tube (6) that communicates with admission passage, launch hole (7) is arranged on the emission tube, and discharge channel (5) communicates through the inner chamber of draining nozzle (8) with valve body (1).Draining nozzle (8) is fixed on the valve gap (2) with bolt (15), and draining nozzle (8) is that billiard table is cylindrical, is made by nonmetallic material, in free half ball float (3) sinks and covers at the intracavity bottom of valve body (1) and with emission tube (6).Outlet port at draining nozzle (8) is equipped with safety check, and this safety check is made up of guide holder (9), spring (10) and guide rod (11), and the sealing surface of guide rod (11) bottom is plane (12) or inclined-plane (13) or arc surface (14).
The working procedure of free half float ball type steam drain valve is like this: when bringing into use, free half ball float sinks in the valve pocket bottom, water of condensation is under the inlet outlet pressure differential effect, flow into body cavity through admission passage and emission tube from launch hole, then through the draining nozzle with the guide rod of safety check boost make length of spring compressed deformation after, discharge from discharge channel.After steam entered, the water of condensation in free half ball float was extruded, and suffered buoyancy increases and upwards floats, coincide with the draining nozzle, at this moment, the guide rod of safety check moves downward under the effect of recoil of spring power, the outlet port of its sealing surface and draining nozzle coincide, and drain valve is in resistance vapour non-return state.When water of condensation once more during freedom of entry half ball float, a part of vapor condenses Cheng Shui in free half ball float, the buoyancy that free half ball float is subjected to reduces and sinks, the guide rod of safety check is pushed open once more by water of condensation, drain valve is got back to hull-borne again, so go round and begin again, reach the effect of resistance vapour, draining, non-return.
The utility model compared with prior art has the following advantages:
1, the draining nozzle is that billiard table is cylindrical, is made by nonmetallic materials, and wear-resisting, shock-resistant, performance is more stable.
2, constitute static soft seal between draining nozzle and free half ball float, not easy to wear, longer service life.
3, safety check has been installed, itself has had check function, and water outlet end need not external again safety check, has improved self performance, has saved the energy, resource, has reduced engineering cost.
Therefore, it is present ideal a kind of Automatic steam trap Trap.
Claims (3)
1, free half float ball type steam drain valve comprises valve gap, valve body and free half ball float, and launch tube is arranged in the valve body, and the draining nozzle is installed on the valve gap, it is characterized in that the draining nozzle is that billiard table is cylindrical, is made by nonmetallic material.
2, free half float ball type steam drain valve comprises valve gap, valve body and free half ball float, and launch tube is arranged in the valve body, and the draining nozzle is installed on the valve gap, it is characterized in that in the outlet port of draining nozzle safety check being installed, and is made up of guide holder, spring and guide rod.
