Abstract
The utility model discloses a throttler for a voltage regulator, which can filter gas entering the throttler. The throttler comprises a gas inlet on a throttling valve, a throttling valve stem and a gas inlet channel located between the gas inlet and the throttling valve stem, and a gas filtering structure is disposed in the gas inlet channel. The gas filter structure can be structures such as a filter screen, a filter membrane or a ventilating filter pipe and the like. By the aid of the gas filtering structure, blockages of the throttler and a pilot valve are avoided. The throttler is favorable for maintaining long-term stable and normal operation of the voltage regulator.
Description
Technical field
The utility model relates to a kind of flow controller, relates in particular to a kind of transmission ﹠ distribution and send flow controller on the pressure governor of using in the gas burning system.
Background technique
In recent years, along with the high speed development of Chinese national economy, the convection cell transmission ﹠ distribution send the requirement of equipment more and more higher.The high speed development of China's gas usefulness gas particularly, to the operation of relevant device whether steadily, negotiability and volume size requirements be higher, requires lower to equipment failure rate.Conventional pressure governor can play the pressure regulation effect, but because combustion gas is sent in the process in transmission ﹠ distribution and can be mingled with some impurity, these impurity make flow controller of installing on the pressure governor and the pilot valve that links to each other with flow controller stop up easily, and then make the pressure governor cisco unity malfunction.
The model utility content
The technical problem that the utility model solves provides a kind of flow controller that is used for pressure governor that can filter gas.
The technological scheme that its technical problem that solves the utility model adopts is: the flow controller that is used for pressure governor, comprise suction port, throttle valve lever and the gas-entered passageway between suction port and throttle valve lever on the throttle valve body, be provided with gas filtering structure in the described gas-entered passageway.
Further be: described gas-entered passageway comprises main passage and the bypass passage that is communicated with the main passage, and described main passage one end links to each other with throttle valve lever, and the main passage the other end forms closed end by the enclosed construction shutoff; One end of described bypass passage is described suction port, and the other end is the air outlet; Described gas filtering structure is the ventilative chimney filter that is arranged in the main passage, described ventilative chimney filter axially with the parallel to an axis of main passage, along the chimney filter of breathing freely circumferentially be provided with the air guide cavity, the air outlet of bypass passage is communicated with the air guide cavity.
Further be: described ventilative chimney filter is the metal screen pipe.
Further be: described enclosed construction is a plug screw, and an end of described ventilative chimney filter is positioned at the closed end of main passage, and the diameter of the closed end of described main passage is more than or equal to the external diameter of ventilative chimney filter.
The beneficial effects of the utility model are: owing to be provided with gas filtering structure in gas-entered passageway, the gas that enters flow controller can be earlier through after the gas filtering structure filtration, enter again in other structure, can prevent from effectively to prevent the obstruction of flow controller and pilot valve like this.
Description of drawings
Fig. 1 is the schematic representation that is used for the flow controller of pressure governor of the present utility model.
Be labeled as among the figure: 1-closed end, 2-air outlet, 3-bypass passage, 4-suction port, 5-gas-entered passageway, 6-throttle valve lever, 7-main passage, the 8-chimney filter of breathing freely, 9-throttle valve body, 10-plug screw, 11-air guide cavity.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
As shown in Figure 1, be used for the flow controller of pressure governor, comprise suction port 4, throttle valve lever 6 and the gas-entered passageway 5 between suction port 4 and throttle valve lever 6 on the throttle valve body 9, be provided with gas filtering structure in the described gas-entered passageway 5.The above-mentioned gas filtration can be for being connected in structures such as filter screen in the gas-entered passageway 5 or filter membrane, and gas can continue transported to the impurities that is mingled with in the gas in other structure with the gas after filtering after through filter screen or filter membrane, for example is transported in the pilot valve.
In order to improve the filtering effect to gas, described gas-entered passageway 5 comprises main passage 7 and the bypass passage 3 that is communicated with main passage 7, and described main passage 7 one ends link to each other with throttle valve lever 6, and main passage 7 the other ends form closed end 1 by the enclosed construction shutoff; One end of described bypass passage 3 is described suction port 4, and the other end is air outlet 2; Described gas filtering structure is the ventilative chimney filter 8 that is arranged in the main passage 7, described ventilative chimney filter 8 axially with the parallel to an axis of main passage 7, along the chimney filter 8 of breathing freely circumferentially be provided with air guide cavity 11, the air outlet 2 of bypass passage 3 is communicated with air guide cavity 11.Above-mentioned ventilative chimney filter both can allow the tube wall of gas by ventilative chimney filter in the bypass passage 3 enter in the main passage 7, can the impurity that be mingled with in the gas be filtered again, in addition, above-mentioned air guide cavity 11 can import its inside with the gas in the bypass passage 3, because air guide cavity 11 circumferentially is provided with along ventilative chimney filter 8, therefore gas can enter in the main passage 7 along the ventilative chimney filter 8 that circumferentially sees through of ventilative chimney filter 8, like this in to gas filtration, also can not influence the proper flow of gas, promptly can not reduce the gas communication ability because of ventilative chimney filter 8 is set.The mode of execution of above-mentioned ventilative chimney filter can have multiple, for example can on the tubing of certain intensity, have a plurality of through holes, on outer pipe wall or pipe material inner wall, coat one or more layers gas permeable material again, as ventilated membrane, cotton, gas permeable materials such as sponge so both can allow gas pass through, and can filter gas again; Above-mentioned ventilative chimney filter also can be sponge tube etc.For simplified structure, be convenient to installation, maintenance and use, the preferred implementation of above-mentioned ventilative chimney filter is: described ventilative chimney filter 8 is the metal screen pipe, the i.e. tubing of making by metal screen, so promptly convenient the installation, convenient for maintaining and use again, gas can enter in the main passage 7 by the tube wall of metal screen pipe, and the impurity that is mingled with in the gas can be filtered by metal screen again.
In addition, the above-mentioned enclosed construction that is used for the closed end 1 of shutoff main passage 7 can be the part of throttle valve body 9, and promptly the closed end 1 of main passage 7 is a blind hole, and above-mentioned enclosed construction also can be structures such as plug.For closed end being carried out on the basis of excellent sealing, ventilative chimney filter 8 can conveniently be set in main passage 7 again or make things convenient for the chimney filter 8 of to breathe freely in main passage 7, to take out, described enclosed construction is a plug screw 10, one end of described ventilative chimney filter 8 is positioned at the closed end 1 of main passage 7, and the diameter of the closed end 1 of described main passage 7 is more than or equal to the external diameter of ventilative chimney filter 8.After using a period of time, need to change when breathing freely chimney filter 8, the plug screw 10 of can outwarding winding, the closed end 1 of main passage 7 is open-minded, and then can be with the chimney filter 8 of breathing freely 7 interior taking-ups from the main passage, then new ventilative chimney filter 8 is put into the relevant position of main passage 7 by closed end 1, screwing plug screw 10 can be again with closed end 1 shutoff.
