Abstract
The utility model relates to a leading main valve for controlling a gas safety heat supply ratio, which belongs to the technical field of the safety adjustment and control of gas and is main composed of a general valve body (3), a gas channel (1), a gas outlet (14), a main valve opening (10), an inflow and outflow channel (15), an adjustable direct gas outflow channel (16), a gas discharge channel (11), a servo pressure adjusting device gas inflow channel (2), a diaphragm (4), a leading connecting rod (8), etc., wherein the general valve body (3) is provided with a general cover plate (13). The gas channel (1) is arranged on the general valve body. The diaphragm (4) is arranged on the upper part of the general cover plate and is provided with a baffle plate (5). The leading connecting rod (8) is arranged on the upper part of the baffle plate and is provided with a main valve opening seal block (9), a leading spring (6) and a plastic guiding sleeve (7). During operation, the diaphragm is upwards pushed or downwards moves by adjusting the pressure of airflow which flows through the inflow and outflow channel by a leading ratio valve and enters an air cavity, and thus, the main valve opening is opened and closed. Thereby, the great flow amount output of the gas can be adjusted. The utility model has reasonable design. The flow amount and the pressure of the gas can be controlled by adjusting the pressure of the cavity. The utility model is suitable for combustion equipment and is matched with a gas safety heat supply ratio control system.
Description
Technical field
The utility model relates to a kind of gas safe heat supply proportion control guide's main valve, and the safety that belongs to combustion gas is regulated the control technology field.
Background technology
The adjusting of guide proportion in the existing gas safe heat supply ratio control system, mainly finish by the guide proportion valve, have outlet and flow to functions such as conversion and ratio adjusting, because the difference on the structural design, ubiquity defectives such as degree of regulation is not high, outlet pressure is unstable, the shut-in time is long.
Summary of the invention
The purpose of this utility model provides a kind of reasonable in design, can effectively realize pressure balance, regulates big flow output, gas safe heat supply proportion control guide's main valve of quick closedown.
The utility model is gas safe heat supply proportion control guide's main valve, comprise total valve body with total cover plate, be opened in blast tube and gas outlet on total valve body, it is characterized in that also offering on total valve body the primary valve that is connected with blast tube and gas outlet respectively; The top of total cover plate is provided with the diaphragm of band baffle plate, and the top of baffle plate is provided with guide's connecting rod of band primary valve sealing block and guide's spring, is air cavity between total cover plate and the diaphragm; Also offer the access way that is connected with guide proportion valve and air cavity respectively on described total valve body.During work, enter the stream pressure of air cavity, make on the diaphragm top or move down, open or close primary valve, thereby regulate the big flow output of combustion gas by regulating by the guide proportion valve access way of flowing through.
Described guide's connecting rod also can be with the plastics guide pin bushing outward, to guarantee the freedom that slides up and down of guide's connecting rod, improves action sensitivity.
Also can offer the adjustable direct gas off-take that is connected with guide proportion valve and gas outlet respectively on described total valve body, the venting road.Also can offer the servo pressure regulator inlet channel on described total valve body.
The utility model adopts the airtight air cavity pressure regulating mechanism that is made of diaphragm, air cavity, total cover plate etc., and is reasonable in design, can effectively realize pressure balance by regulating the control of air cavity pressure enforcement to gas flow pressure, regulates big flow output, quick closedown.Be suitable in the fields such as flame control, boiler control, domestic heating and accurate proportion control of combustion apparatus and the supporting use of gas safe heat supply ratio control system.
Description of drawings
Accompanying drawing is an overall structure cutaway view of the present utility model.
Among the figure: 1 is blast tube, and 2 is the servo pressure regulator inlet channel, and 3 is total valve body, 4 is diaphragm, and 5 is baffle plate, and 6 is guide's spring, 7 is the plastics guide pin bushing, and 8 is guide's connecting rod, and 9 is the main valve sealing block, 10 is primary valve, and 11 are the venting road, and 12 is air cavity, 13 is total cover plate, 14 is the gas outlet, and 15 is access way, and 16 is adjustable direct gas off-take.
The specific embodiment
The utility model is mainly by the total valve body 3 with total cover plate 13, be opened in blast tube 1, gas outlet 14, primary valve 10, access way 15, adjustable direct gas off-take 16, venting road 11, servo pressure regulator inlet channel 2 on total valve body 3, place the diaphragm 4 of total cover plate 13 top band baffle plates 5, place the formations such as guide's connecting rod 8 of baffle plate 5 top band primary valve sealing blocks 9, guide's spring 6, plastics guide pin bushing 7.Between total cover plate 13 and the diaphragm 4 is air cavity 12, primary valve 10 is connected with blast tube 1 and gas outlet 14 respectively, access way 15 is connected with guide proportion valve and air cavity 12 respectively, and adjustable direct gas off-take 16 and venting road 11 are connected with guide proportion valve and gas outlet 14 respectively.
Below in conjunction with embodiment structure of the present utility model and operation principle are further described:
When the admission pressure in guide's proportioning valve increases, combustion gas is in access way 15 enters air cavity 12, the influence that makes diaphragm 4 increased by air cavity 12 internal pressures is upwards pushed up, connecting shaft mechanism through baffle plate 5, guide's connecting rod 8, primary valve sealing block 9, overcome the pressure reduction of the spring force of guide's spring 6 and deadweight, guide's primary valve 10, open guide's primary valve 10, combustion gas directly enters gas outlet 14 by blast tube 1 through primary valve 10.
When after guide's proportioning valve operate as normal, closing, gas in the air cavity 12 directly flows out to gas outlet 14 through access way 15, adjustable direct gas off-take 16, venting road 11, air cavity 12 internal gas pressures reduce up to zero, primary valve sealing block 10 moves down under the spring pressure of guide's connecting rod 8, baffle plate 5, diaphragm 4 gravity and guide's spring 6, closes guide's primary valve 10.
