Detailed Description

In the following, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present application. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.

As shown in fig. 1 and fig. 2, as an aspect of the embodiments of the present application, the present embodiment provides a piping system, including: a thermostatic valve 1, a first line 2 and a fastener 3.

The thermostatic valve 1 has at least one first interface end 11, a pair of insertion holes 111 are arranged on the outer side wall of the first interface end 11 at intervals and oppositely, and the pair of insertion holes 111 are communicated with the inside of the first interface end 11. The first pipe 2 has a first pipe joint 21, the first pipe joint 21 is inserted into the first joint end 11, a first groove 211 is provided on an outer side wall of the first pipe joint 21, and the first groove 211 corresponds to the position of the pair of insertion holes 111. The fastener 3 has a pair of

insertion arms

31, 32 spaced apart and oppositely disposed, and the pair of

insertion arms

31, 32 penetrates the pair of insertion holes 111 and is disposed in the first groove 211.

In the embodiment of the present invention, the first interface end 11 may be an interface end made of a metal material such as copper or stainless steel. The receptacle 111 may be integrally formed with the first interface end 11. The first groove 211 may be an annular groove surrounding the first pipe joint 21, or may be a non-annular groove corresponding to the position of the pair of insertion holes 111, which is not limited in the embodiment of the present application. Preferably, the first groove 211 is an annular groove that surrounds the first pipe joint 21.

In the embodiment of the present application, the first pipe joint 21 is inserted into the first interface end 11, and after the pair of

insertion arms

31 and 32 are inserted into the pair of insertion holes 111, they are confined in the first groove 211, so as to prevent the first pipe joint 21 from coming out, and achieve quick assembly of the first interface end 11 and the first pipe joint 21.

The insertion hole 111 may be a circular hole, a square hole, or a hole of any other shape, which is not limited in the embodiment of the present application. It will be appreciated that the bore of the socket 111 is larger than the outer diameter of the

socket arms

31, 32. In the case where the insertion hole 111 is a square hole, the longitudinal direction of the square hole is parallel to the radial direction of the first interface end 11. In one example, the pair of receptacles 111 may be through the entire first interface end 11, i.e., through the two opposing sidewalls of the first interface end 11; or may be a sidewall extending through the first interface end 11.

The width and depth of the annular groove are adapted to the outer diameter of the plugging

arms

31, 32 so that the plugging

arms

31, 32, after insertion into the annular groove, cooperate with the annular groove to define the position of the first pipe fitting 21 and to secure the first pipe fitting 21.

In one example, the spacing of the pair of plugging

arms

31, 32 is greater than or equal to the spacing of the pair of insertion holes 111. After the pair of

insertion arms

31, 32 are inserted into the pair of insertion holes 111, they are tensioned outward, thereby further achieving the fastening function.

As shown in fig. 2, in one embodiment, the pair of plugging

arms

31, 32 includes a first plugging arm 31 and a second plugging arm 32, and the lengths of the first plugging arm 31 and the second plugging arm 32 are different. That is, one of the first and

second insertion arms

31 and 32 has a longer length and the other has a shorter length. In the case of inserting the pair of plugging

arms

31, 32 into the pair of insertion holes 111, the longer one of the plugging

arms

31, 32 may be inserted into one of the insertion holes 111 first, and in the case of the shorter one of the plugging

arms

31, 32 being close to the other insertion hole 111, the longer one of the plugging

arms

31, 32 is rotated to align the shorter one of the plugging

arms

31, 32 with the other insertion hole 111, thereby facilitating the insertion of the plugging

arms

31, 32 into the pair of insertion holes 111. It can be known that, in the case that the lengths of the first plugging arm 31 and the second plugging arm 32 are the same, the two plugging

arms

31 and 32 need to be aligned with the two insertion holes 111 and then inserted at the same time, which requires a long time for alignment, and thus the assembly efficiency is affected. The length of this application embodiment through first grafting arm 31 and second grafting arm 32 is different, can further make things convenient for the assembly, improve assembly speed.

In one embodiment, the fastener 3 further comprises a connecting rod 33, one end of the connecting rod 33 is connected with the first insertion arm 31, and the other end of the connecting rod 33 is connected with the second insertion arm 32. In one example, the shape of the connecting rod 33 matches the shape of the first interface end 11 such that insertion of the fastener 3 into the first interface end 11 fits over the first interface end 11, reducing the protruding structure. In one example, the connecting rod 33 is shaped as a straight rod or as a rod having a convex shape such that with the fastener 3 inserted into the first interface end 11, the connecting rod 33 does not fully fit over the first interface end 11. Under the condition that the fastener 3 needs to be disassembled, the protruding part can be conveniently held by hands to be pulled out, and the disassembling and assembling speed is improved. In one example, in the case that the shape of the connecting rod 33 matches with the shape of the first interface end 11, the connecting rod 33 can be held by hand to pull out and quickly detach the fastening member 3 by setting a pair of

insertion arms

31 and 32 to a proper length. For example, after the pair of plugging

arms

31 and 32 are inserted into the pair of insertion holes 111, the connecting rod 33 is not sleeved on the first interface end 11, i.e. the fastening is realized, and then the fastening member 3 can be pulled out by holding the connecting rod 33, so that the quick detachment is realized.

In one embodiment, the first and second plugging

arms

31 and 32 are disposed at an angle between 3 ° and 20 °. When the first and

second insertion arms

31 and 32 are inserted into the pair of insertion holes 111, the outward tension is exerted, and the fastening function is further achieved.

In one example, the fastener 3 has a pair of spaced and oppositely disposed insertion arms: a first plug-in arm 31 and a second plug-in arm 32. The first and second plugging

arms

31, 32 are connected and the first and second plugging

arms

31, 32 are arranged at an angle, which may be 15 °. After the first inserting arm 31 and the second inserting arm 32 are inserted into the pair of insertion holes 111, the connecting portion of the first inserting arm 31 and the second inserting arm 32 can be used as a handheld portion to pull out the fastener 3, so that the first inserting arm 31 and the second inserting arm 32 can be detached conveniently, and the detaching efficiency is improved. As an example, the lengths of the first and second plugging

arms

31 and 32 may be the same. As an example, the lengths of the first and second plugging

arms

31, 32 may be adapted to the outer diameter of the first interface end 11.

In one example, the first and second plugging

arms

31 and 32 may be mutually independent plugging arms, i.e. the first and second plugging

arms

31 and 32 are not connected to each other. In the case of assembling the piping, the first and second plugging

arms

31 and 32 are respectively inserted into the pair of insertion holes 111. The first and

second arms

31, 32 or the receptacle 111 or the first interface end 11 may be provided with means for preventing the first and

second arms

31, 32 from passing out of the receptacle 111.

In one embodiment, at least one second groove 212 is further disposed on the outer sidewall of the first pipe joint 21, and a sealing member 213 is disposed in the second groove 212. Preferably, the number of the second grooves 212 is two, and the two second grooves 212 are respectively provided with the sealing members 213 therein. In the embodiment of the present application, the sealing member 213 is disposed in the second groove 212, so that the first interface end 11 and the first pipe joint 21 are connected in a sealing manner, the sealing performance of the piping system is improved, and liquid is prevented from flowing out. As one example, the seal 213 may be an O-ring seal.

In one example, the first pipe 2 has a first pipe joint 21, the first pipe joint 21 is inserted in the first interface end 11, a first groove 211 and at least one second groove 212 are provided on the outer side wall of the first pipe joint 21, and a seal 213 is provided in the second groove 212. The at least one second groove 212 of the first pipe joint 21 is inserted into the first interface end 11 after being sleeved with the seal, the first groove 211 is aligned with the positions of the pair of insertion holes 111, and the pair of

insertion arms

31 and 32 of the fastener 3 are defined in the first groove 211 through the pair of insertion holes 111. With the seal 213 fitted in the second groove 212, the first pipe joint 21 is in interference fit with the first interface end 11, so that the first pipe joint 21 is in sealed connection with the first interface end 11. The outward tension of the pair of

insertion arms

31, 32 causes the fastener to define the first groove 211 more firmly.

In one example, in the case where the axial length of the first groove 211 is larger than the outer diameter of the first or

second socket arm

31 or 32 so that the first or

second socket arm

31 or 32 is defined in the first groove 211 through a pair of insertion holes, the position of the first pipe joint 21 can also be adjusted.

In one embodiment, the fastener 3 is made of a spring steel material. On the one hand, the first and

second insertion arms

31 and 32 may have outward tension when penetrating the pair of insertion holes 111, and further achieve the fastening effect. On the other hand, the spring steel has higher tensile strength, elastic limit and high fatigue strength, so that the spring steel still does not deform under long-term alternating stress, and the service life of a pipeline system is prolonged.

In one example, the first and

second insertion arms

31 and 32 are made of a spring steel material, and the material of the connection rod 33 or the connection portion of the first and

second insertion arms

31 and 32 may not be limited.

In one embodiment, the first trench 211 is a ring-shaped groove structure. The size of the groove is adapted to the outer diameter of the first and second plugging

arms

31, 32. With the pair of

plug arms

31, 32 inserted into the pair of insertion holes 111 into the first interface end 11 and into the first groove 211, the

plug arms

31, 32 can be inserted further inward around the annular groove, so that the

plug arms

31, 32 have a greater outward tension, improving their fastening performance.
