Embodiment Construction

[0038] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.

[0039] A waterway control valve assembly, such as Figure 1-Figure 2 As shown, it includes a valve body 1 with a water inlet 11 and a water outlet 12, a valve core set 2 installed in the valve body 1, a diaphragm gland 3 and a shaft sleeve 4, and a valve body is formed between the water inlet 11 and the water outlet 12. Through the hole 13, the diaphragm gland 3 is installed above the spool set 2, and the spool set 2 is arranged above the through hole 13.

[0040] The spool kit 2 is composed of a rubber diaphragm 21, a spool body 22 and a water-stop rubber pad 23 from top to bottom. The spool body 22 is provided with a water inlet channel 24, and the lower part of the spool body 22 has a convex post 221. A balance hole 222 is defined at the lower end of the boss 221 , one end of the balance hole 222 communicates

Abstract

The invention discloses a waterway control valve unit, comprising a valve element suite, a diaphragm gland, and a shaft sleeve. The diaphragm gland is arranged on the valve element suite. The valve element suite is formed by a rubber diaphragm, a valve element main body, and a watertight rubber pad from top to bottom. The valve element main body is internally provided with a water inlet duct. The lower end of the valve element main body is provided with the watertight rubber pad in a clamping manner. The upper end of the valve element main body is provided with the rubber diaphragm in a clamping manner. A hydraulic pressure balance chamber is formed between the rubber diaphragm and the diaphragm gland. The diaphragm gland is internally provided with a diversion hole communicated with the hydraulic pressure balance chamber. The diaphragm gland is internally provided with a discharge hole which is isolated from the diversion hole. The diaphragm gland is internally provided with a decompression flow channel along the radial direction of the diaphragm gland. The shaft sleeve is sleeved on the rubber diaphragm. A flowing hole is arranged in the shaft sleeve. The waterway control valve unit also comprises a valve body used to install the valve element suite. After the waterway control valve unit is installed with a corresponding waterway control mechanism in a cooperative manner, water hammer vibration can be prevented, and pressure resistance is good, and service life of a product is long.
