Problems solved by technology

The structure realizes the opening and closing of the valve by rotating the valve core. The sealing system has many parts (including seals, spring rings, spring sheets, valve cores, O-rings), complex structure, and troublesome assembly, resulting in long assembly hours and reliable operation. The performance is poor, the internal leakage of the water valve is relatively large, and the first-time assembly pass rate of the product is low
Due to structural constraints, although several quality rectifications have been carried out, there has not been much improvement so far

Embodiment Construction

[0015] The present invention will now be further described in conjunction with specific examples, and the following examples are intended to illustrate the present invention rather than further limit the present invention.

[0016] Such as figure 2 , 3 The pressure-bearing and sealing structure of a water valve shown includes an upper cover 1 and a lower cover 2 connected up and down with a water channel in the middle, the lower cover 2 is connected to the water inlet, and the upper and lower covers 1 and 2 are provided with a water flow control valve. The valve structure includes the valve plate 3 installed at the joint of the upper and lower covers 1 and 2, the rotating shaft 4 that drives the valve plate 3 to rotate, and the combined sealing ring 9 that fits the valve plate 3 to form a sealing surface. 3 to control the opening and closing of the water channel, and the valve plate 3 is provided with a water hole 5 to facilitate the passage of water.

Abstract

The invention relates to a pressure-bearing and sealing structure of a water valve. The structure comprises an upper cover and a lower cover which are vertically connected, wherein a water channel is formed between the upper cover and the lower cover, the lower cover is communicated with a water inlet, a plate valve structure for controlling passing of a water flow is arranged between the upper and lower covers and comprises a valve plate, a rotating shaft and a combined sealing ring, the valve plate is mounted in a position where the upper and lower covers are connected, the rotating shaft drives the valve plate to rotate, the combined sealing ring is attached to the valve plate to form a sealing surface, opening and closing of the water channel are controlled through rotation of the valve plate, and water holes for facilitating passing of the water flow are formed in the valve plate. The structure has the benefits as follows: sealing system parts are few, the structure is simple, assembly is convenient, the reliability is high, the operating torque is small, the internal leakage amount is small, and the one-time assembly percent of pass of the product is high.

Description

technical field [0001] The invention relates to a water valve pressure-bearing and sealing structure. Background technique [0002] The existing water valve is a ball valve structure, such as figure 1 Show. The structure realizes the opening and closing of the valve by rotating the valve core. The sealing system has many parts (including seals, spring rings, spring sheets, valve cores, O-rings), complex structure, and troublesome assembly, resulting in long assembly hours and reliable operation. The performance is poor, the internal leakage of the water valve is relatively large, and the first-time assembly qualification rate of the product is low. Due to structural constraints, although several quality rectifications have been carried out, there has not been much improvement so far. Contents of the invention [0003] The technical problem to be solved by the present invention is: based on the above problems, the present invention provides a water valve pressure-bearing...
