Valve body structure of three-way adjusting valve

Abstract

The invention discloses a valve body structure of a three-way adjusting valve. The valve body structure comprises a valve body with a water incoming passage and two water outgoing passages, one water outgoing passage and the water incoming passage are on a same straight line, the other water outgoing passage is perpendicular to the same straight line, two shaft seats with rotating shaft holes in two sides are positioned at a junction of the water outgoing passages which are perpendicular and adjacent and arranged in a direction perpendicular to the water outgoing passage, a serial-connection concave notch used in an inner cavity of the valve body to open and close a valve element is formed between the shaft seats on two sides, flanges for connecting pipelines are arranged and integrally made outside two water outgoing passage ports and a water incoming passage port respectively, and a square frame bottom is arranged at the bottom of the valve body, namely at the symmetric bottom edges of the water outgoing passages in vertical arrangement; valve element airtight passages allowing a spherical valve element or a turning plate body valve element to correspond are arranged in cavities inside the water outgoing passages in vertical arrangement respectively. The valve body structure has the advantages of simple structure and convenience in mounting and arranging.

Description

technical field [0001] The invention relates to a valve body structure of a three-way regulating valve used for flow regulation and flow distribution, and belongs to the technical field of three-way valves. Background technique [0002] The three-way regulating valve is a common valve. The existing three-way regulating valve is generally a ball valve, which is usually only used for the diversion, confluence and flow direction switching of the medium in the pipeline; the opening position of the valve core is usually 90°. In this case, a certain pipeline is either in the fully open position or in the fully closed position, that is, the spool of the three-way valve is a ball spool, which cannot realize flow regulation and flow distribution, and can only Realize the change of flow direction; although there are some three-way ball valves that can realize flow regulation and flow distribution, the valve body is equipped with a valve body water inlet channel and two valve body wate...

Problems solved by technology

[0002] The three-way regulating valve is a common valve. The existing three-way regulating valve is generally a ball valve, which is usually only used for the diversion, confluence and flow direction switching of the medium in the pipeline; the opening position of the valve core is usually 90°. In this case, a certain pipeline is either in the fully open position or in the fully closed position, that is, the spool of the three-way valve is a ball spool, which cannot realize flow regulation and flow distribution, and can only Realize the change of flow direction; although there are some three-way ball valves that can realize flow regulation and flow distribution, the valve body is equipped with a valve body water inlet channel and two valve body water outlet channels. The opening angle is used to adjust and distribute the flow area and flow of the water outlet channel of the valve body, but the structure of this three-way regulating ball valve is relatively complicated. For example, a three-way ball valve for flow regulation and flow distribution is disclosed in the patent No. ZL 201110215393.4 , it can achieve the purpose of adjusting and changing the flow area and flow rate of the water outlet channel of the valve body while keeping the flow area and flow rate of the water inlet channel of the valve body unchanged. The specific structure is: including the valve body, the sphere, the described The valve body is provided with a valve body water inlet channel and two valve body water outlet channels, and the valve body water inlet channel and the valve body water outlet channel meet each other in the inner cavity of the valve body, and the ball is arranged on the inner cavity of the valve body , the sphere is provided with a sphere water inlet channel and two sphere water outlet channels, and a sphere water inlet channel and two sphere water outlet channels on the sphere are respectively connected with a valve body water inlet channel and two sphere water outlet channels on the valve body The water outlet channels of the valve body are arranged in one-to-one correspondence, and the sphere water inlet channel on the sphere is connected with one of the two sphere water outlet channels; the three-way ball valve with the above structure also has defects such as complex structure, inconvenient use, and high manufacturing cost.
