The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

A plain water pump coupling 100 according to an embodiment of the present invention is described below with reference to fig. 1-2.

According to the utility model discloses plain type water pump adapter 100, include: body 1, elbow fitting 2, gate valve 3 and check valve assembly 4.

Wherein, body 1 vertical extension and body 1 can be equipped with into water flow path in, and the upper end of body 1 can be equipped with water inlet 1a, and water can enter into water flow path through water inlet 1 a. One end of the elbow joint 2 can be connected with the lower end of the body 1, and the other end of the elbow joint 2 can be connected with the gate valve 3. For example, as shown in fig. 1, a first flange 11 is provided at a lower end of the body 1, a second flange 21 and a third flange 22 are provided at both axial ends of the elbow joint 2, respectively, a fourth flange 31 is provided on the gate valve 3, the first flange 11 and the second flange 21 are bolted to connect the body 1 and the elbow joint 2 together, and the third flange 22 and the fourth flange 31 are bolted to connect the elbow joint 2 and the gate valve 3 together.

As shown in fig. 1-2, the check valve assembly 4 may be provided in the elbow fitting 2, the check valve assembly 4 may include a base 41 and a check device 42, the base 41 may be connected to an inner peripheral wall of the elbow fitting 2 to completely block a water inlet passage in the elbow fitting 2, a water through hole may be provided in the base 41, the check device 42 may be connected to the base 41 and the check device 42 may move back and forth with respect to the base 41 to open or close the water inlet passage.

Specifically, the water pressure in the water inlet passage may act on the check device 42 through the water through hole. When the water pressure is greater than the set value, the check device 42 is separated from the seat 41 and moves in a direction away from the seat 41 (a forward direction as shown in fig. 1), thereby allowing the water inlet passage to be opened. When the water pressure is less than the set value, the check device 42 may move toward a direction close to the seat 41 (a backward direction as shown in fig. 1) and closely fit to the seat 41, thereby blocking the water inlet passage. From this, through the above-mentioned setting, through set up check valve assembly 4 in elbow fitting 2, check valve assembly 4 not only can play the effect of switching on and cutting off inhalant canal, but also can make plain type water pump adapter 100's overall structure compacter, can make plain type water pump adapter 100 easy to assemble and transport.

According to the utility model discloses plain type water pump adapter 100 through set up check valve assembly 4 in elbow fitting 2, can make plain type water pump adapter 100's overall structure compacter under the prerequisite that satisfies the user demand, not only saves assembly space, makes plain type water pump adapter 100 easy to assemble and transport moreover.

As shown in fig. 2, in some embodiments of the present invention, the check device 42 may include a valve seat 421, a driving rod 422 and a spring 423, wherein, in the flowing direction of water (the direction from back to front as shown in fig. 1), the valve seat 421 may be disposed at the downstream of the base 41 and the valve seat 421 may move back and forth relative to the base 41, one end of the driving rod 422 may be connected to the valve seat 421, the other end of the driving rod 422 is disposed through the base 41, the spring 423 may be sleeved outside the driving rod 422, and the two axial ends of the spring 423 may be respectively abutted against the base 41 and the driving rod 422.

Specifically, the water pressure in the water inlet passage may act on the check device 42 through the water through hole. When the water pressure is greater than the set value, the valve seat 421 is separated from the base 41 and moved in a direction away from the base 41 (forward direction as shown in fig. 1) by the water pressure, whereby the water inlet passage can be conducted. When the water pressure is lower than the set value, the spring 423 may drive the driving rod 422 to drive the valve seat 421 to move toward the direction close to the base 41 (the backward direction as shown in fig. 1) and to be closely attached to the base 41, thereby blocking the water inlet passage. Therefore, through the arrangement, the overall structure of the check device 42 is simpler and the operation is more convenient.

As shown in fig. 2, in some embodiments of the present invention, the base 41 may include a main body 411 and a guiding portion 412, the main body 411 may be formed in a disc shape, and the main body 411 may be matched with the inner peripheral wall of the elbow joint 2 to stop the water inlet channel, the guiding portion 412 is disposed at the position of the circle center of the main body 411, the guiding portion 412 extends toward the upstream (backward as shown in fig. 1) of the water flowing direction relative to the main body 411, the driving rod 422 is inserted into the guiding portion 412, and the guiding portion 412 may play a guiding role for the driving rod 422, thereby making the operation of the check device 42 more stable and smooth. Alternatively, the ratio of the extended length of the guide 412 to the length of the drive rod 422 may be 1/6.

In some embodiments of the present disclosure, check device 42 may further include: and a sealing gasket (not shown) which may be disposed on a side wall of the valve seat 421 near the base 41 (such as a rear side shown in fig. 2), wherein the sealing gasket may make the valve seat 421 and the base 41 fit more tightly, so as to prevent leakage when the water inlet channel is closed.

Optionally, the sealing gasket may be an elastic material, for example, the sealing gasket may be a rubber material, or may also be a silicone material, and the sealing gasket has good elasticity, so that the sealing effect of the sealing gasket can be further improved.

Alternatively, the packing and the valve seat 421 may be formed as an integral molding member, whereby the overall structure of the check device 42 may be made simpler, and the assembly efficiency of the plain type water pump coupling 100 may be improved.
