Problems solved by technology

[0004] However, the solution provided by this patent also has disadvantages: First, the tight connection between the plastic pipe and the metal valve adopts a press-fit method, and the connection is not firm, and the plastic pipe is easy to separate from the valve or rotate with the valve
Secondly, through the connection of the fastening piece, since the fastening piece needs to be stuck between the valve and the plastic pipe, the production requirements for the fastening piece are relatively high. If it is too large, it will damage the plastic pipe if it is too small. solid effect

Embodiment Construction

[0023] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0024] As shown in Figure 1, the valve includes a valve stem 1, a handle 2, a valve core 3 arranged in a valve body 4, and a valve body 4 made of metal material. One end of the valve stem 1 is connected to the valve core 3, and the other end is Pass through the valve body 4 and connect with the handle 2. The end of the valve body 4 has a water pipe 5, and the water pipe 5 is provided with a connecting pipe 6 made of plastic. The material used for the plastic is PPR. Directly connect the connecting pipe 6 to the end of the water pipe 5 . The two ends of the water pipe 5 of this valve are connected with the upper connecting pipe 6 to facilitate the connection with other plastic pipe fittings.

[0025] Specifically, in order...

Abstract

The invention provides a valve, belonging to the technical field of valve. The valve solves the technical problems of poor sealing effect, bad connecting effect between a plastic pipe and the valve and the like of the existing valve. The valve comprises a valve body made of metal materials, a water service pipe arranged at the end part of the valve body and a connecting pipe which is made of plastics, arranged at the position of the water service pipe and is directly and fixedly connected with the water service pipe by a method of injection molding. The valve is has advantages that the end part of the water service pipe of the valve body has good leak tightness, the structure is simple, and the connecting pipe is firmly connected with water service pipe, etc.

Description

technical field [0001] The invention belongs to the technical field of valves and relates to a valve. Background technique [0002] A general valve includes a valve body, a valve stem, a handle, and a valve core. One end of the valve stem is connected to the valve core, and the other end passes through the valve body to be connected to the handle. When existing various metal valves are connected with plastic pipes, when the two ends of the valve body are connected with plastic pipes, they are usually connected with flanges. The construction process of flange connection is complicated, the sealing of the joint cannot be guaranteed, the types and quantities of workpieces required are large, the construction and leak testing time is long, and the processing cost of a single joint is high. [0003] For this reason, Chinese patent authorization announcement number is that CN2750159Y discloses " a kind of connector of plastic pipe and metal valve that transports fluid ", improves...
