Abstract
A fast opening and closing silent check valve for a boiler comprises a valve body, a valve clack, a guide positioning support, a sealing ring and a cylindrical spring. The inside of valve body is equipped with the valve pocket, fixedly connected with direction locating support on the valve pocket inner wall, both ends are equipped with export and import respectively about the valve body, through direction locating support fixed connection there is the valve clack in the valve pocket, the junction of valve clack and valve body is equipped with the sealing washer, and it is sealed vice that valve clack and sealing washer constitute, the upper and lower side end of valve clack all is through cylindrical spring and the upper and lower end fixed connection of direction locating support, and cylindrical spring is in between valve clack and the direction locating support. The advantages are that: the cylindrical spring is convenient for the rapid opening and closing of the silent check valve, the valve body is in contact with the valve clack without noise, and the sealing performance between the valve clack and the valve body is ensured by the sealing ring.
Description
Technical Field
The utility model relates to a quick open-close silence check valve on boiler steam pipe, especially a boiler is with opening-close silence check valve fast.
Background
The boiler check valve is a valve which is used for automatically opening and closing a valve clack by means of medium flowing per se and is used for preventing medium backflow of a boiler steam pipeline, and belongs to an automatic valve which is mainly used for preventing medium backflow, preventing a pump and a driving motor from reversing and discharging container medium. This design provides a boiler is with opening and close silence check valve fast, sets up the direction locating support in that the valve body is inside, and the direction locating support passes through cylindrical spring fixed connection valve clack, and the quick of the silence check valve of being convenient for is opened and close, reaches the noiselessness of contact between valve clack and the valve body, and the valve clack is equipped with the sealing washer with the junction of valve body, and the valve clack constitutes sealed vice with the sealing washer, and sealing performance is good.
Disclosure of Invention
The utility model provides a boiler is with opening and close silence check valve fast, including valve body, valve clack, direction locating support, sealing washer, cylindrical spring.
The utility model adopts the following technical scheme: the inside of valve body is equipped with the valve pocket, fixedly connected with direction location support on the valve pocket inner wall, both ends are equipped with export and import respectively about the valve body, there is the valve clack through direction location support fixed connection in the valve pocket, and the valve clack is for taking the stainless steel material of sphere, and the junction of valve clack and valve body is equipped with the sealing washer, and the sealing washer is high temperature resistant, the nonmetal material that the resilience is strong, and the valve clack constitutes sealed vice with the sealing washer, and the cross-section of valve clack and sealing washer is the arc.
Furthermore, the upper side end and the lower side end of the valve clack are fixedly connected with the upper end and the lower end of the guide positioning support through cylindrical springs, and the cylindrical springs are located between the valve clack and the guide positioning support.
The utility model has the advantages that: the cylindrical spring is convenient for quickly opening and closing the silent check valve, the valve body is in contact with the valve clack without noise, and the sealing performance between the valve clack and the valve body is good due to the arrangement of the sealing ring.
Drawings
Fig. 1 is a schematic structural view of the present invention;
in the figure, 1, a valve body, 2, an outlet, 3, an inlet, 4, a guiding and positioning support, 5, a valve cavity, 6, a valve clack, 7, a sealing ring and 8, a cylindrical spring.
Detailed Description
The utility model will be further described with reference to the accompanying drawings and embodiments, as shown in fig. 1, a fast open/close silent check valve for boiler comprises a valve body 1, a guiding and positioning support 4, a valve flap 6, a sealing ring 7, and a cylindrical spring 8, wherein the valve body 1 is internally provided with a valve cavity 5, the inner wall of the valve cavity 5 is fixedly connected with the guiding and positioning support 4, the left and right ends of the valve body 1 are respectively provided with an outlet 2 and an inlet 3, the medium flows from the inlet 3 to the outlet 2, the medium returns from the outlet 2 to the inlet 3, the valve flap 6 is fixedly connected in the valve cavity 5 through the guiding and positioning support 4, the valve flap 6 is made of stainless steel with a spherical surface, the sealing ring 7 is arranged at the joint of the valve flap 6 and the valve body 1, the sealing ring 7 is made of non-metal material with high temperature resistance and strong resilience, the valve flap 6 and the sealing ring 7 form a sealing, the valve clack 6 is tightly attached to the sealing ring 7, and the sealing performance between the valve body 1 and the valve clack 6 is ensured.
Furthermore, the upper side end and the lower side end of the valve clack 6 are fixedly connected with the upper end and the lower end of the guide positioning support 4 through cylindrical springs 8, the cylindrical springs 8 are located between the valve clack 6 and the guide positioning support 4, and the cylindrical springs 8 play a role in contracting the valve clack 6, so that the valve body and the valve clack are in contact without noise.
The working principle is as follows: when the check valve is used, the flow direction is from the inlet 3 to the outlet 2, the valve clack is separated from the sealing ring by the working pressure of a medium, and the cylindrical spring 8 is driven to compress towards the outlet 2, so that the check valve is convenient to open; when the check valve is closed, the check direction is from the outlet 2 to the inlet 3, the valve clack 6 and the sealing ring 7 are tightly attached by the medium countercurrent and the resilience of the cylindrical spring 8, the purpose of closing the check valve is achieved, the valve body and the valve clack are in contact without noise, and the sealing performance of the valve body and the valve clack is ensured.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
