Abstract

A valve comprising housing body, partition plate, and collecting device. The housing body defines a housing cavity. The partition plate is provided in the housing cavity. A leakage passage extends along the partition plate through the housing body. The collecting device comprises a lower piece, an upper piece, and a connector connecting them. The upper piece and the lower piece cover a leakage passage upper port and a leakage passage lower port, respectively. The lower piece comprises a collecting cavity communicating with the leakage passage lower port. The lower piece and lower part of the housing body are provided with lower fitting assembly. The upper piece and upper part of the housing body are provided with an upper fitting assembly. The lower piece and the upper piece are fitted on the housing body in place by means of the lower fitting assembly, the upper fitting assembly and the connector.

First claim

We claim:

1. A valve, comprising:
a housing body, the housing body defining a housing cavity, the housing cavity extending transversely through the housing body;
a partition plate, provided in the housing cavity to divide the housing cavity into a left cavity and a right cavity, a leakage passage being provided in and extends along the partition plate through the housing body, with a leakage passage lower port and a leakage passage upper port formed on the housing body; and
a collecting device, the collecting device comprising a lower piece, an upper piece and a connector connecting the lower piece and the upper piece, wherein the upper piece is configured to cover the leakage passage upper port and the lower piece is configured to cover the leakage passage lower port, and wherein the lower piece comprises a collecting cavity communicating with the leakage passage lower port,
wherein the lower piece and a lower part of the housing body are provided with a lower fitting assembly, the upper piece and an upper part of the housing body are provided with an upper fitting assembly, and the lower piece and the upper piece are fitted on the housing body in place by means of the lower fitting assembly, the upper fitting assembly, and the connector.

2. The valve according to claim 1 , wherein the lower fitting assembly comprises a housing lower fitting part provided on the housing body and a lower piece fitting part provided on the lower piece, and wherein the upper fitting assembly comprises a housing upper fitting part provided on the housing body and an upper piece fitting part provided on the upper piece.

3. The valve according to claim 2 , wherein the housing lower fitting part and the housing upper fitting part are disposed symmetrically with respect to an axis of the housing body.

4. The valve according to claim 2 ,
wherein the housing lower fitting part and the housing upper fitting part protrude out of an outer surface of the housing body, and wherein the lower piece fitting part is a recess in the lower piece and the upper piece fitting part is a recess in the upper piece.

5. The valve according to claim 4 ,
wherein the housing lower fitting part and the housing upper fitting part are respectively wedge-shaped,
wherein the wedge-shaped housing lower fitting part comprises a first blocking surface and a first inclined surface connected with the first blocking surface, the first inclined surface being closer to the connector than the first blocking surface, and
wherein the wedge-shaped housing lower fitting part comprises a second blocking surface and a second inclined surface connected with the second blocking surface, the second inclined surface being closer to the connector than the second blocking surface.

6. The valve according to claim 1 ,
wherein the housing body further comprises a left limiter and a right limiter, wherein the left limiter and the right limiter respectively protrude out of an outer surface of the housing body, so that a connector receiving part is formed between the left limiter and the right limiter to receive the connector.

7. The valve according to claim 1 ,
wherein the collecting device is made in one piece from plastic.

8. The valve according to claim 1 ,
wherein the partition plate is provided with a shaft accommodating hole transversely penetrating through the partition plate and used for accommodating a shaft, and wherein the shaft accommodating hole is in communication with the leakage passage.

9. The valve according to claim 8 ,
wherein the housing body further comprises a left sealing plate and a right sealing plate, the left sealing plate and the right sealing plate are connected with left and right surfaces of the partition plate around the shaft accommodating hole, respectively, and wherein the valve further comprises:
the shaft, the shaft being disposed through the shaft accommodating hole;
a first seal, the first seal being annular, wherein an inner wall of the first seal abuts against the shaft and an outer wall of the first seal abuts against the left sealing plate such that the left cavity and the leakage passage are sealed from each other by the first seal; and
a second seal, the second seal being annular, wherein an inner wall of the second seal abuts against the shaft and an outer wall of the second seal abuts against the right sealing plate such that the leakage passage and the right cavity are sealed from each other by the second seal.

10. The valve according to claim 1 , wherein the left cavity is used for accommodating a driving component, and the right cavity is used for accommodating a valve body of the valve.
