Problems solved by technology

[0002] The pressure valve is realized by opening the valve without a specific pressure. The existing pressure valve is mainly composed of a valve body, a valve cover, a valve disc and a spring. The disc compresses the spring to discharge the water. When the pressure value decreases, the valve disc will block the passage in the valve seat again under the action of the spring. Because the valve disc often reciprocates, the contact surface between the valve disc and the valve seat is severely worn, often Grooves appear, shorten the service life, and require frequent replacement of the valve disc, which not only wastes time, but also requires frequent replacement

Embodiment Construction

[0012] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0013] Such as figure 1 A leak-proof pressure valve shown includes a valve seat 1 and a valve cover 2, the valve cover 2 is installed on the valve seat 1, the valve cover 2 is provided with a drain hole 3, and the middle of the valve seat 1 is provided There is a fluid channel 7, the upper part of the fluid channel 7 is tapered, and a trapezoidal plugging core 5 is provided at the upper taper of the fluid channel 7. There are three trapezoidal plugging cores 5, and the trapezoidal plugging core 5 at the top is A pressure spring 4 is provided between the top of the valve cover 2, and a connecting piece is provided between each two adjacent trapezoidal plugging cores 5; the drain hole 3 is located at the top or side of the valve cover 2; The connector is a spring 6 or a cylinder 8.

[0014] The water flow enters through the fluid channel 7. When the pressure of the w...

Abstract

The invention relates to a leakage-proof pressure valve which comprises a valve base and a valve cover, and the valve cover is installed on the valve base. Drain holes are formed in the valve cover, a fluid channel is formed in the middle of the valve base, the upper portion of the fluid channel is in a cone shape, trapezoid plug cores are arranged at the cone-shaped position of the upper portion of the fluid channel, and the number of the trapezoid plug cores is at least two. A pressure spring is arranged between the trapezoid plug core at the top end and the top of the valve cover, and a connecting piece is arranged between every two adjacent trapezoid plug cores. By the adoption of the structure, because the multiple trapezoid plug core structures are adopted, other plug cores can be used normally after one plug core leaks, and therefore service life of the pressure valve is prolonged.

Description

technical field [0001] The invention relates to a valve structure in the valve manufacturing industry, in particular to a leak-proof pressure valve. Background technique [0002] The pressure valve is realized by opening the valve without a specific pressure. The existing pressure valve is mainly composed of a valve body, a valve cover, a valve disc and a spring. The disc compresses the spring to discharge the water. When the pressure value decreases, the valve disc blocks the passage in the valve seat again under the action of the spring. Because the valve disc often reciprocates, the contact surface between the valve disc and the valve seat is severely worn, often Grooves appear, shorten the service life, and require frequent replacement of the valve disc, which not only wastes time, but also requires frequent replacement. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a leak-proof pressure valve that does no...
