Abstract
The utility model relates to a steam valve. The steam valve comprises a valve body, a valve seat and a heavy ball and is characterized in that internal threads on the inner side wall of the valve body are in fit with external threads on the valve seat, when the valve body and the valve seat are tightly screwed together, a steam chamber is formed between the inner wall of the valve body and the valve seat, the heavy ball is arranged in the steam chamber, a steam hole penetrating from top to bottom is arranged in the middle of the valve seat, the slope radian of a steam hole outlet is matched with the spherical radian of the heavy ball, the height of the steam chamber is larger than the diameter of the heavy ball, the diameter of the heavy ball is larger than the width of the steam hole on the valve seat, a steam jet hole is arranged in the valve body, close to upper portion of the steam chamber, fastening screw holes transversely penetrating through the valve body are arranged in positions, close to the bottom, of the valve body, and the valve seat can be fastened in the valve body in the mode that fastening screws pass through the fastening screw holes after the valve body is tightly screwed with the valve seat. By adoption of the design, the steam valve has the advantages of being simple in structure, convenient to machine and maintain, stable, reliable, and the like.
Description
Technical field
The utility model relates to a kind of steam valve, is exactly a kind of technological improvement that the steam valve that exists is on the market carried out specifically.
Background technique
The steam valve that exists on the market at present, the steam valve that especially liquid is heated structurally substantially all exists defective, and the adverse current phenomenon easily occurs in liquid in steam valve, and break-off also easily occurs in long-term the use between valve body and the valve seat.
Summary of the invention
The purpose of this utility model is to design a kind of steam valve, to improve the operation stability of steam valve.
In order to realize purpose of the present invention, the technical solution adopted in the utility model is: design a kind of steam valve, comprise valve body, valve seat, heavy ball three parts, it is characterized in that, internal thread on the valve body madial wall matches with outside thread on the valve seat, when valve body after valve seat closely is screwed onto, between valve interior wall and valve seat, form a steam chest, heavy ball is positioned in the steam chest, have one in the middle of the valve seat and run through steam vent up and down, the domatic radian in steam vent outlet port and the sphere radian of heavy ball are complementary, and the steam chest height is greater than the heavy ball diameter, the heavy ball diameter is greater than the width of valve seat upper steam vent, above close steam chest on the valve body, be provided with jetted hole, near bottom position, the fastening screw that traverses valve body arranged at valve body, when valve body after valve seat closely is screwed onto, can by fastening screw valve seat be fastened in the valve body with fastening screw.
Because the domatic radian in valve seat upper steam vent outlet port and the sphere radian of heavy ball are thought coupling, when vapor pressure was low, heavy ball can better prevent the steam generation leakage.
Jetted hole number on the valve body is pressed actual working pressure, be arranged to one or more more than.
Fastening screw hole number is according to the size of steam valve, is arranged to one or morely, guarantees that valve seat can be fastened in the valve body.
The actual pressure size of steam valve is pressed in heavy ball, can select unlike material, such as metal or pottery etc.
The advantages such as employing the design's steam valve has simple in structure, processing, easy to maintenance, and is reliable and stable
Description of drawings
Fig. 1 is sectional view of the present utility model;
Fig. 2 is the assembled sectional view of valve body and valve seat in the utility model;
Fig. 3 is the sectional view of valve body in the utility model;
Fig. 4 is the sectional view of valve seat in the utility model.
Among the figure: 1, valve body, 2, valve seat, 3, heavy ball, 4, steam chest, 11, jetted hole, 12, fastening screw, 21, steam vent, 22, domatic.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figures 1 to 4, valve seat (2) closely is screwed onto in the valve body (1), and fastening by the fastening screw (12) on the valve body (1) with fastening screw, and it is inner that heavy ball (3) is built in steam chest (4).When the vapor pressure in the vaporium reaches the specified breakout pressure of steam valve, steam is by the steam vent (21) on the valve seat (2), with heavy ball (3) jack-up, steam enters steam chest (4) and arranges from steam valve by the jetted hole (11) on the valve body (1).When the vapor pressure in the vaporium during less than the breakout pressure of steam valve, heavy ball (3) falls because of free gravity, heavy ball (3) spherical seal gets lodged in domatic (22) on the valve seat (2), because heavy ball (3) sphere radian and domatic (22) radian are complementary, heavy ball (3) can effectively prevent the steam generation leakage in the vaporium.
Claims (1)
1. steam valve, comprise valve body (1), valve seat (2), heavy ball (3) three parts, it is characterized in that, internal thread on valve body (1) madial wall matches with outside thread on the valve seat (2), when valve body (1) after valve seat (2) closely is screwed onto, between valve body (1) inwall and valve seat (2), form a steam chest (4), heavy ball (3) is positioned in the steam chest (4), there is one in the middle of the valve seat (2) and runs through steam vent (21) up and down, domatic (22) radian in steam vent (21) outlet port and the sphere radian of heavy ball (3) are complementary, steam chest (4) height is greater than heavy ball (3) diameter, heavy ball (3) diameter is greater than the width of valve seat (2) upper steam vent (21), be provided with jetted hole (11) in the upper top near steam chest (4) of valve body (1), near bottom position, the fastening screw (12) that traverses valve body (1) is arranged at valve body (1).
