Description
Technical Field
The utility model relates to a technical field that the valve industry was made, in particular to governing valve structure.
Background
The valve usually realizes the function of opening and closing water flow by isolating the water inlet and the water outlet through the valve core, and when the valve core is operated by the existing valve, the pressure of the water inlet and the pressure of the water outlet reach the same or close instantly, so that the thrust of the valve core actuating mechanism is adjusted to be larger, the adjusting precision is lower, and particularly when the water level of a boiler is controlled, the fluctuation of the water level is larger.
Disclosure of Invention
To the technical problem, the utility model provides a governing valve structure, its thrust that has reduced case actuating mechanism effectively improves the regulation precision of water level.
The technical scheme is as follows: the utility model provides a governing valve structure, its includes valve body and valve gap, set up water inlet and delivery port on the valve body, correspond on the valve body the water inlet with be provided with the case between the delivery port, the case passes through the disk seat and connects the valve body, valve rod, its characterized in that are connected to the case: the valve body is provided with a cage corresponding to the valve core, the valve core moves in the cage in a guiding way, and a plurality of cage water outlets which are gradually increased are arranged on the cage.
The water outlet of the cage cover is further characterized by being arranged in a triangular shape; the diameter of the water outlet is 3mm-10 mm; a circumferential valve core groove is formed in the valve core, a packing gasket sealing ring is arranged on the valve core groove, an elastic check ring for a shaft is arranged at the upper end of the sealing ring, and the sealing ring is abutted to the cage; the valve core is provided with balance holes which penetrate through the upper end and the lower end of the valve core; a packing pad is arranged between the valve rod and the valve cover; the filler pad is made of chromium material.
The above structure is adopted in the utility model, correspond on the valve body the case is provided with the cage, and the case is in guiding motion in the cage, the cage is covered and is arranged a plurality of cage delivery ports that increase gradually, gets into the delivery port, has avoided the rivers sudden increase of delivery port end, has reduced case actuating mechanism's thrust, has realized the high accuracy of rivers and has adjusted.
Drawings
FIG. 1 is a schematic view of the structure of the regulating valve of the present invention;
fig. 2 is a schematic diagram of a water outlet structure of the cage.
Detailed Description
The present invention will be further explained with reference to the drawings and examples.
Referring to fig. 1 and 2, a regulating valve structure comprises a valve body 1 and a valve cover 2, wherein a water inlet 3 and a water outlet 4 are arranged on the valve body 1, a valve core 5 is arranged between the water inlet 3 and the water outlet 4 on the valve body 1, the valve core 5 is connected with the valve body 1 through a valve seat 6, the valve core 5 is connected with a valve rod 7, a cage 8 is arranged on the valve body 1 corresponding to the valve core 5, the valve core 5 moves in the cage 8 in a guiding manner, a plurality of cage water outlets 9 which are gradually increased are arranged on the cage 8, the cage water outlets are arranged in a triangular manner, the diameter of the water outlet is 3mm-10mm, the valve core acts, water flow at the water inlet flows into the water outlet through the cage, the water flow enters the water outlet due to the arrangement of the plurality of cage water outlets which are gradually increased, the water flow at the water outlet end is prevented from being suddenly increased, the thrust of a valve, can also realize better regulation effect on water with poor water quality.
The valve core 5 is provided with a circumferential valve core groove 10, the valve core groove 10 is provided with a packing gasket sealing ring 11, the upper end of the sealing ring 11 is provided with an elastic check ring 12 for a shaft, the sealing ring 11 is abutted against the cage cover 8, the sealing ring prevents liquid from leaking from the valve core, zero leakage of the valve is realized, the elastic check ring ensures the stability of the installation of the sealing ring, and the valve core prevents the displacement of the sealing ring in the motion process.
The valve core 5 is provided with a balance hole 13, and the balance hole 13 is penetrated through the upper end and the lower end of the valve core 5 to realize the upper end and the lower end of the valve core
The balance of the pressure reduces the thrust of the actuating mechanism.
A chromium material packing pad 14 is arranged between the valve rod 7 and the valve cover 2, so that leakage of the valve is effectively prevented.
The present invention and the embodiments thereof have been described above schematically, and the description is not limited thereto, and the embodiment shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto, and those skilled in the art will be suggested by the teachings thereof, and without departing from the spirit of the present invention, without creatively designing the structural mode and the embodiments similar to the technical solution, all of which shall fall within the protection scope of the present invention.
