Embodiment Construction
[0015] Such as figure 1 As shown, the elements that make up the balanced pressure control valve of the present invention include: a water inlet valve body 10 , a water outlet valve body 20 , a valve sleeve 30 , a valve plug 40 and a spring 50 .
[0016] The lower end of the water inlet valve body 10 is provided with a water inlet 11, and the upper end is provided with a connecting portion. The upper end of the water outlet valve body 20 is provided with a water outlet 21, and the lower end is provided with a connecting portion. After the connecting portion of the water inlet valve body 10 is connected with the connecting portion of the water outlet valve body 20, the entire valve body is formed. The whole valve body is hollow, and the water inlet 11 and the water outlet 21 are respectively located at the upper and lower ends of the valve body.
[0017] The valve sleeve 30 is arranged inside the valve body and is in sealing connection with the water inlet valve body 10 . The ...

The invention relates to a balance-pressure control valve. The balance-pressure control valve is characterized in that a valve body is hollow and provided with a water inlet and a water outlet, and a valve sleeve is provided with a water passing hole; a valve plug is hollow and provided with an opening end, and the side wall of the valve plug is provided with a water passing hole; the valve sleeve is arranged in the valve body, and the valve plug is slidably arranged in the valve sleeve, so that the water inlet of the valve body communicates with the water outlet of the valve body just through the opening end of the valve plug, the water passing hole formed in the valve plug and the water passing hole formed in the valve sleeve; and the valve plug is provided with a spring matching part, a spring is arranged in the valve sleeve, and one end of the spring is matched with the spring matching part of the valve plug. According to the balance-pressure control valve, the spring (50) is arranged in the valve sleeve (30) and located over the valve plug (40), one end of the spring abuts against the upper end of the valve sleeve (30), and the other end of the spring is matched with the spring matching part of the valve plug (40). The balance-pressure control valve further comprises a first sealing ring (81) and a second sealing ring (82) which are arranged between a water inlet valve body (10) and a water outlet valve body (20) as well as the valve sleeve (30) and the water inlet valve body (10) correspondingly.
Description
technical field [0001] The invention relates to the field of plumbing equipment, in particular to a pressure balance control valve. Background technique [0002] In the bathing water supply system of hotels, homes, etc., the temperature of the mixed outlet water usually changes greatly due to the pressure fluctuation of the cold or hot inlet water. If the pressure of the hot water inlet is too high, the temperature of the mixed water outlet will be too high, which may cause burns to the user; if the pressure of the cold water inlet is too high, the temperature of the mixed water outlet will be too low, making the user feel uncomfortable; The pressure may be constantly changing, so that the temperature of the mixed water fluctuates. [0003] Most of the existing bathing equipment needs to manually adjust the water flow to make the water temperature meet the usage requirements. This method is loaded down with trivial details, and in the whole bathing process, often will repe...
