Detailed Description

In order to better understand the scheme of the application, the following detailed description is provided for the application with the accompanying drawings and the detailed description.

It should be understood that the terms "first," "second," "third," and the like, are used for limiting the components, are used for distinguishing the components, and have no special meaning if not stated otherwise, and therefore, should not be construed as limiting the scope of the present application. In the description of the present application, "plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

Referring to FIG. 1, FIG. 1 illustrates a multi-spool bimetallic strip and orifice plate combination large drain trap. As shown in fig. 1, the multi-core bimetal and orifice plate type combined drain valve for large drainage comprises: the valve comprises a valve body 1 and a valve cover 2, wherein the valve cover 2 covers the valve body 1, and a first cavity 3 is arranged between the valve cover 2 and the valve body 1.

The valve body 1 is provided with a water inlet channel 11, a water outlet channel 12, a second cavity 13 and a plurality of bimetallic strip type steam trap valve cores 14. The first cavity 3 and the second cavity 13 are communicated through a valve core 14 of the double-metal-sheet type steam trap, and the water inlet channel 11 is communicated with the second cavity 13. In addition, a first connecting channel 15 is also arranged on the valve body 1, and the first connecting channel 15 is communicated with the first cavity 3 and the water outlet channel 12.

It will be appreciated that the bimetallic strip trap valve cartridge 14 may include a bimetallic strip, a valve seat and a valve cartridge arranged in sequence from top to bottom. The valve core can be movably connected with the bimetallic strip through a connecting rod, the connecting rod can penetrate through the valve seat through the first channel, and a spring can be arranged on the connecting rod; when the bimetallic strip deforms, the connecting rod can be driven to move towards the upper part of the valve core 14 of the bimetallic strip type drain valve, so that the valve core of the valve core 14 of the bimetallic strip type drain valve is in close contact with the first channel. A second passage may also be provided in the valve seat, which second passage may communicate the first cavity 3 with the first passage. When low-temperature condensate water appears in the second cavity 13, the bimetallic strip on the valve core 14 of the bimetallic strip type steam trap is flat, the valve core of the valve core 14 of the bimetallic strip type steam trap is in an opening position under the elasticity of a spring, and then condensate water and gas can flow into the first cavity 3 from the second cavity 13 through the first channel and the second channel, so that the condensate water can be discharged quickly; when the temperature of the condensed water gradually rises, the bimetallic strip temperature sensing element on the valve core 14 of the bimetallic strip type steam trap starts to bend and deform, and the valve core of the valve core 14 of the bimetallic strip type steam trap is pushed to the closing position until the valve core of the valve core 14 of the bimetallic strip type steam trap is completely closed, and at the moment, the valve core of the valve core 14 of the bimetallic strip type steam trap completely seals the first channel. It will be appreciated that the bimetallic strip on the bimetallic trap cartridge 14 can be preheated faster and thus operate more sensitively in the event that condensate is drained in time.

In one example, the valve body 1 is provided with a plurality of connecting holes (not shown in the figure), the number of the connecting holes is the same as that of the valve core 14 of the double-metal-sheet type steam trap, and the valve core 14 of the double-metal-sheet type steam trap is fixedly connected with the connecting holes. Illustratively, the connecting hole may be internally threaded, and the bimetallic trap valve cartridge 14 may be externally threaded, so that the two may be threadedly connected.

In one example, the valve body 1 is further provided with at least one orifice 16 of an orifice type steam trap, the orifice 16 of the orifice type steam trap is communicated with the first cavity 3 and the second cavity 13, and the inner diameter of the orifice 16 of the orifice type steam trap is smaller than the preset inner diameter. Illustratively, the predetermined inner diameter may be 5 mm. For example, the hole 16 of the orifice-plate type steam trap can enable condensed water to enter the first cavity 3 in time, and because the inner diameter of the hole 16 of the orifice-plate type steam trap is small, the hole can prevent gas from being discharged to the greatest extent when the condensed water is discharged, and the phenomenon of gas source waste caused by a large amount of gas entering the first cavity 3 is avoided. In addition, the hole 16 of the orifice plate type steam trap can prevent the occurrence of air resistance phenomenon under the condition of not influencing gas leakage, so that the steam trap can continuously drain water, and the reliability of the steam trap is improved. In addition, the working environment of the bimetallic strip metal valve is also improved, so that the bimetallic strip metal valve is in a good working environment.

In one example, the valve body 1 and the bonnet 2 are connected by bolts.

It should be noted that, in the embodiment of the present application, each component may be assembled in a general assembly manner in the current industry, and a connection manner between general components may also be connected in a general connection manner in the current industry, which is not described herein again.

It can be understood that when the displacement of the existing steam trap is increased, the displacement is generally increased by the number of the steam traps, for example, the displacement of one steam trap is a, and if a steam trap with the displacement of 2a is required, two steam traps are required, which increases the use cost, occupies a large space and is very inconvenient. Furthermore, limited by the volume of the spool in a trap, it is not possible to increase the displacement by increasing the volume of the trap and the volume of one spool therein, e.g., the spool of a trap is typically a two-piece spool, and it is not possible to increase the displacement of a trap by increasing the volume of a two-piece spool, and therefore, it is currently difficult to increase the displacement of a single trap. In the scheme, the valve core of the drain valve is arranged on the valve body of the drain valve, so that the purposes of improving the discharge capacity and the drainage efficiency of the drain valve are achieved, and the improvement is remarkable.

To sum up, the big discharge capacity trap of bimetallic strip and orifice plate formula combination of multicore formula that this application embodiment provided arranges a plurality of bimetallic strip formula trap spools on the valve body of trap, has reached the purpose that promotes the discharge capacity and the hydrophobic efficiency of trap from this.

The multi-core bimetallic strip and orifice plate combined drain valve with large drainage volume provided by the application is described in detail above. The principles and embodiments of the present application are explained herein using specific examples, which are merely set forth to aid in understanding the core concepts of the present application. It should be noted that, for those skilled in the art, it is possible to make several improvements and modifications to the present application without departing from the principle of the present application, and such improvements and modifications also fall within the scope of the claims of the present application.
