Abstract
The utility model proposes a kind of diaphragm type safety valve, comprise valve body, it is characterized in that: valve body is be communicated with by standpipe the pipeline (runner) formed with transverse tube, standpipe upper end is provided with pressure regulating mechanism, the below of pressure regulating mechanism is provided with the barrier film with pipeline lumen contact, pressure regulating mechanism is can do the structure moved up and down under the effect of barrier film, during this equipment use, when after interior media pressure increase, when reaching setup pressure value, valve is opened automatically, automatically closes after pressure reduces.Its main feature is as follows: 1, be mainly used in water be medium the automatic opening device of needs on.2, add lever opening mechanism, the lifting force of generation is enough to open board-like spool.3, the clean of pressure regulating mechanism working environment can be ensured.4, user be in completely non-maintaining and again school adjust.5, meet outside the requirement of national relevant laws and regulations, reduce the working service of user as much as possible.
Description
Technical field
The utility model relates to a kind of diaphragm type safety valve, is a kind of new-type automatic Open valve of boilers and pressure vessel industry.
Background technique
Take water as the pressure-bearing kind equipment of medium, in long-term work process, after safety valve is opened, because bad environments is difficult to avoid some impurity such as rust, dirt to cause valve closing not tight.The code having country to promulgate at boilers and pressure vessel again, requires that this kind equipment of safety valve is wanted regularly open test manually, avoids the rust that causes owing to being failure to actuate for a long time dead.
Summary of the invention
Model utility object
For above problem, the utility model provides a kind of diaphragm type safety valve, its objective is the deficiency existing for solution equipment in the past.
Technological scheme
A kind of diaphragm type safety valve, comprise valve body, it is characterized in that: valve body is be communicated with by standpipe the pipeline (runner) formed with transverse tube, standpipe upper end is provided with pressure regulating mechanism, the below of pressure regulating mechanism is provided with the barrier film with pipeline lumen contact, pressure regulating mechanism is can do the structure moved up and down under the effect of barrier film, transverse tube is provided with board-like spool, board-like spool is connected linkage with pressure regulating mechanism, board-like spool activity be arranged on flap place, by pipeline temporary sealing, when board-like spool moving disengaging flap, pipeline is opened, during reset, pipeline is resealed.
Pressure regulating mechanism is arranged in pressure regulating cavity, comprise pressure adjusting lever, pressure regulating spring and pressure adjustment cap, pressure adjustment cap is arranged on the upper end of pressure adjusting lever and is arranged on the top of pressure regulating cavity outside, the lower end of pressure adjusting lever is provided with pressure and regulates pressing plate, pressure regulates pressing plate and barrier film to contact, pressure regulating spring is enclosed within pressure adjusting lever, upper end and the pressure regulating cavity upper end inwall of pressure regulating spring contact, and lower end and the spring clip be arranged on pressure adjusting lever of pressure regulating spring contact.
Board-like spool is connected with pressure adjusting lever by lever opening mechanism, and moves up and down under the drive of pressure adjusting lever.
Advantage and effect
The utility model proposes a kind of diaphragm type safety valve, and during this equipment use, when after interior media pressure increase, when reaching setup pressure value, valve is opened automatically, automatically closes after pressure reduces.
Main feature is as follows:
1, be mainly used in water be medium the automatic opening device of needs on.Even if medium contains impurity, the sealing after reliable opening and closing also can be ensured.
2, add lever opening mechanism, the lifting force of generation is enough to open board-like spool.
3, owing to adopting barrier film mode, avoid working medium to contact with pressure regulating mechanism, the clean of pressure regulating mechanism working environment can be ensured.
4, by plant produced according to pressure series regulate after, user be in completely non-maintaining and again school adjust.
5, meet outside the requirement of national relevant laws and regulations, reduce the working service of user as much as possible.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
embodiment:
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described further:
As shown in Figure 1, the utility model is a kind of diaphragm type safety valve, comprise valve body 1, valve body 1 is be communicated with by standpipe the pipeline formed with transverse tube, standpipe upper end is provided with pressure regulating mechanism, the below of pressure regulating mechanism is provided with the barrier film with pipeline lumen contact, pressure regulating mechanism is can do the structure moved up and down under the effect of barrier film, transverse tube is provided with board-like spool 3, board-like spool 3 is connected linkage with pressure regulating mechanism, the activity of board-like spool 3 be arranged on flap place, by pipeline temporary sealing, when board-like spool 3 moving disengaging flap, pipeline is opened, during reset, pipeline is resealed.
Pressure regulating mechanism is arranged in the pressure regulating cavity of standpipe upper end, pressure regulating mechanism comprises pressure adjusting lever 4, pressure regulating spring 7 and pressure adjustment cap 6, pressure adjustment cap 6 is arranged on the upper end of pressure adjusting lever 4 and is arranged on the top of pressure regulating cavity outside, the lower end of pressure adjusting lever 4 is provided with pressure and regulates pressing plate, pressure regulates pressing plate and barrier film to contact, pressure regulating spring 7 is enclosed within pressure adjusting lever 4, upper end and the pressure regulating cavity upper end inwall of pressure regulating spring 7 contact, lower end and the spring clip be arranged on pressure adjusting lever 4 of pressure regulating spring 7 contact.
Board-like spool 3 is connected with pressure adjusting lever 4 by lever opening mechanism 5, and moves up and down under the drive of pressure adjusting lever 4.
Utility model works process is as follows: when device interior pressure medium exceedes setting value, under the effect of device interior pressure medium, barrier film 2 moves up (ultimate range 4mm), barrier film 2 promotes pressure adjusting lever 4 and moves up, pressure adjusting lever 4 is made to drive lever opening mechanism 5 to move upward, then lever opening mechanism 5 drives board-like spool 3 to depart from flap, and high-pressure medium is released, and equipment internal pressure reduces.When equipment internal pressure is recovered, barrier film 2 resets, and then drives pressure adjusting lever 4 to reset downwards, thus makes the reset of board-like spool 3 come back to flap place, is sealed by equipment.
Under the condition that the utility model can require in satisfied national relevant laws and regulations, at utmost reduce the maintenance times of user, greatly save man power and material.
