Detailed Description

Referring to fig. 1-8, an H-shaped five-valve group comprises a valve body 1, two first passages 2 penetrate through the valve body 1, a pressure balancing device is arranged on the valve body 1 and is respectively communicated with two ends of each first passage 2, a stop valve 3 is arranged on the valve body 1 and is far away from the pressure balancing device between two ends of each first passage 2, and an emptying device is arranged on the valve body 1 and is far away from the pressure balancing device and the stop valve 3 between two ends of each first passage 2.

In this embodiment, during the use, the one end of two first channels 2 on the valve body 1 is respectively communicated with two pipelines of the double pipeline through the flange, when the pressure of the liquid flowing out from the two pipelines needs to be balanced, the pressure balancing device can be opened to make the two first channels 2 mutually communicated, so that the pressure in the two first channels 2 is the same, the two stop valves 3 respectively control each pipeline of the double pipeline, so as to realize the switching between the passage and the disconnection of the pipelines, when the liquid in the valve body 1 needs to be emptied, the pressure balancing device is closed, so that the two first channels 2 are not communicated, then the emptying device is opened, so that the emptying device can empty the liquid in the two first channels 2 in the valve body 1, and the problem of how to control the flow rate on the two pipelines when the liquid is used for the connection of the pressure transmitter and the requirement for the inlet of the double pipeline is solved.

As a preferred mode, the pressure balance device includes second passageway 4, balanced cavity 5, first cock body 6, the axis of balanced cavity 5 with the contained angle of the axis of second passageway 4 is between 0 degree to 180 degrees, second passageway 4 runs through two relative lateral walls on the balanced cavity 5, the both ends of second passageway 4 respectively with two communicate between the both ends of first passageway 2, the one end of balanced cavity 5 is in the valve body 1, the other end extends to the surface of valve body 1, be equipped with in the balanced cavity 5 first cock body 6, be equipped with on the first cock body 6 and stretch out first valve rod 7 on the surface of valve body 1. With such a design, since the second channel 4 penetrates through two opposite side walls of the balance chamber 5, when the first plug body 6 is located in the balance chamber 5, the second channel 4 can be cut off, so that no fluid (water, oil, etc.) can flow through the second channel 4, in which case the two first channels 2 are not communicated, and therefore the pressures between the two first channels 2 are different; when the pressure of the liquid in the two first channels 2 flowing out of the valve body 1 needs to be adjusted to be the same, the first valve rod 7 is screwed out of the valve body 1 to enable the first plug body 6 to slide out of the valve body 1, so that the part of the lower part of the balance chamber 5 communicated with the second channel 4 is not blocked by the first plug body 6, at the moment, the two first channels 2 are communicated with each other, and the pressure of the fluid flowing out of the valve body 1 from the two first channels 2 is the same.

Preferably, the axis of the balancing chamber 5 is perpendicular to the axis of the second channel 4. The design is such that the first valve stem 7 is also perpendicular to the axis of the second channel 4, which is convenient for the user to operate.

As a preferred mode, emptying devices includes row cavity 8, second cock body 9, evacuation passageway 10, the axis of row cavity 8 with the contained angle of the axis of first passageway 2 is between 0 to 180 degrees, the lateral wall of row cavity 8 with first passageway 2 intercommunication, the one end of evacuation passageway 10 is in valve body 1, the other end extends to the surface of valve body 1, the one end of evacuation passageway 10 with row cavity 8 is located one end intercommunication in the valve body 1, the other end extends outside the valve body 1, second cock body 9 with the interior cooperation of row cavity 8, be equipped with on the second cock body 9 and extend to the outer one end of valve body 1 from row cavity 8 and stretch out the second valve stem 11 of valve body 1. After the design, when the fluid in the valve body 1 needs to be exhausted, the second valve rod 1 is screwed out of the valve body 1, so that the second plug body 9 slides in the direction out of the valve body 1, the second plug body 9 does not block the communication position between the exhaust cavity 8 and the first channel 2, and the fluid in the valve body 1 flows out of the valve body 1 from the exhaust channel 10.

Preferably, one end of each of the two evacuation cavities 8 communicating with the evacuation channel 10 is located on the same side of the two first channels 2. The design is mainly convenient for evacuation, and when the installation, the first channel 2 can be directly installed downwards towards one side of the evacuation cavity 8, namely, under the installation mode, the first channel 2 which is correspondingly arranged is positioned above the evacuation cavity 8, when the valve body 1 is evacuated, the two evacuation cavities 8 perform the evacuation function at the moment, and liquid generally flows from the height to the lower part.

Preferably, the control rods of the pressure balancing device extend out of the valve body 1 from the upper surface of the valve body 1, the control rods of the two stop valves extend out of the valve body 1 from the left side wall and the right side wall of the valve body 1, and the control rods of the two emptying devices extend out of the valve body 1 from the upper surface of the valve body 1.
