Description

Technical Field

[0001] The utility model relates to the field of steam traps, in particular to a reed-type bimetallic steam trap. Background Art

[0002] A steam trap is an automatic valve, also called a steam-blocking drain valve, which is mainly used to automatically drain condensate from steam heating equipment or pipelines to prevent steam leakage and loss.

[0003] This valve is normally open at room temperature and normally closed at high temperatures. Based on the changes in condensate within the valve cavity, an elastic or thermal element opens and closes the valve core, automatically and timely draining condensate from steam-consuming equipment and the steam pipeline network. When steam from the pipeline network enters the valve cavity, the elastic force or deformation force of the elastic or thermal element drives the valve core to close. After a period of operation, when a certain amount of condensate forms in the pipeline network, a sensing element (such as a float, spring, thermal deformation plate, or water level sensor) controls the valve to reopen and drain the condensate. When condensate discharge is complete, the valve automatically resets and closes, repeating a cycle of "open-close-open-close" to ensure timely condensate drainage.

[0004] However, traditional steam traps have the problem of slow startup, which leads to steam leakage. Utility Model Content

[0005] Based on this, in order to solve the problem of slow startup and steam leakage in traditional steam traps, the utility model provides a reed bimetallic steam trap, the specific technical solution of which is as follows:

[0006] A reed-type bimetallic steam trap comprising

[0007] A valve body, wherein a flow channel is provided in the valve body and passes through the valve body;

[0008] a through pipe, through which the flow channel passes;

[0009] The switch assembly includes a sliding block and a metal sheet that can deform and restore its deformation as the steam temperature changes. One end of the metal sheet is connected to the valve body, and the other end of the metal sheet is connected to the sliding block. The metal sheet is used to drive the sliding block to move back and forth and control the abutment state between the sliding block and the through pipe; the through pipe and the sliding block abut and cooperate to control the connectivity state of the flow channel.

[0010] The reed-type bimetallic steam trap features a metal plate that deforms and recovers with changes in steam temperature. When the metal plate comes into contact with steam, it rapidly deforms, pulling a sliding block, which then abuts against the through-tube, preventing steam leakage. This reed-type bimetallic steam trap solves the problem of slow startup and steam leakage associated with traditional steam traps.

[0011] Furthermore, the flow channel includes a first opening, a first channel, a second channel, a cavity, a third channel and a second opening that are connected in sequence.

[0012] Furthermore, the outer contour of the metal sheet is arranged in an arc shape, and the metal sheet is arranged in the cavity.

[0013] Furthermore, the valve body is provided with a third opening communicating with the first channel, and a filter is provided in the first channel; the valve body is provided with a threaded cover, and the threaded cover is threadedly connected to the third opening.

[0014] Furthermore, the through-tube is arranged in the third channel, one end of the through-tube is arranged in the cavity, and the other end of the through-tube is inserted into the third channel.

[0015] Furthermore, the sliding block includes a sliding rod portion and an abutting portion, one end of the sliding rod portion is disposed in the cavity, and the other end of the sliding rod portion passes through the through tube and is connected to the abutting portion.

[0016] Furthermore, one end of the through pipe arranged in the cavity is arranged in a stepped shape, the metal sheet is sleeved on the stepped end of the through pipe, and the stepped end of the through pipe cooperates with the valve body to clamp the metal sheet; the metal sheet is connected to the sliding rod part.

[0017] Furthermore, a first inclined surface is provided on one end of the through pipe away from the cavity, a second inclined surface is provided on the abutting portion, and the first inclined surface is in sealing abutment with the second inclined surface. BRIEF DESCRIPTION OF THE DRAWINGS
