Abstract

The utility model relates to a vertical stop valve with an installing hole, which comprises a valve body and a valve seat, wherein the lower portion of the valve body is connected with the valve seat,the bottom portion of the valve seat is provided with a valve installing hole, a thread pin is arranged in the valve installing hole, the thread pin is fixedly arranged on a refrigerating unit, the valve seat is fixedly connected with the refrigerating unit through the valve installing hole and the thread pin, and the valve seat is connected with a thread side connecting pipe. When a valve rod upwardly moves to a highest position, the thread side connecting pipe is communicated with a flared tube, because of using the vertical stop valve with the installing hole, and the problems that the installing structure of a prior stop valve is not reasonable and refrigerant of a refrigerating system can not be supplied are solved. The vertical stop valve with the installing hole has the characteristics of simple structure, convenient disassembly, excellent sealing performance, and reliable use performance.

Description

The vertical stop valve of band mounting hole

Technical field

The utility model relates to a kind of vertical stop valve with mounting hole, belongs to refrigeration plant auxiliary products technical field.

Background technique

On the compressor intake and exhaust pipeline of small-sized refrigerating unit, use at present stop valve, exist bigger defective: the one, mounting structure is unreasonable, stop valve is directly connected on the compressor intake and exhaust pipeline, there is not other mounting connection structure, the weight of stop valve is born by pipeline fully like this, owing to during the cooling machine set operation vibration is arranged, so the less stable of stop valve also causes the leakage of connecting pipeline easily; The 2nd, the stop valve that uses does not have and can carry out the structure that refrigeration agent replenishes to refrigeration system at present.

Summary of the invention

The utility model provides a kind of vertical stop valve of band mounting hole of novelty, adopts the vertical stop valve technology of multifunctional combined structure, realizes that vertical stop valve mounting structure is reasonable and can easily carry out the purpose that refrigeration agent replenishes to refrigeration system.

The technical solution adopted in the utility model is:

A kind of vertical stop valve with mounting hole, comprise: valve body, valve seat, be connected with a valve seat in the bottom of valve body, the valve seat bottom is provided with a valve mounting hole, in the valve mounting hole threaded is installed, and threaded is fixedly installed on the cooling machine set, valve seat is fixedlyed connected with cooling machine set by valve mounting hole, threaded, be connected and installed with whorl side and take on valve seat, when valve rod was moved upwards up to the extreme higher position, whorl side was taken over and is communicated with flared tube.

On valve body, also be equipped with and fill the fluorine mouth, when valve rod is moved down into extreme lower position, fills the fluorine mouth and communicate with flared tube.

The valve seat bottom can also be provided with a mounting plates structure, and valve seat is fixedlyed connected with cooling machine set by mounting plates structure.

The utility model beneficial effect is:

Owing to adopted the vertical stop valve of band mounting hole of the present utility model, it is unreasonable and can not carry out the problem that refrigeration agent replenishes to refrigeration system to have solved existing stop valve mounting structure, and the vertical stop valve of band mounting hole of the present utility model has: simple in structure, easy accessibility, good airproof performance, usability reliable characteristics.

Embodiment

As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5.

The vertical stop valve of band mounting hole, by: valve body 1, valve rod 2, valve seat 3, flared tube 4, whorl side take over 5, fill fluorine mouth 6, threaded 8 is formed.

A kind of vertical stop valve with mounting hole, comprise: valve body 1, valve seat 3, be connected with a valve seat 3 in the bottom of valve body 1, valve seat 3 bottoms are provided with a valve mounting hole 7, and threaded 8 is installed in the valve mounting hole 7, and threaded 8 is fixedly installed on the cooling machine set, valve seat 3 is fixedlyed connected with cooling machine set by valve mounting hole 7, threaded 8, be connected and installed with whorl side and take over 5 on valve seat 3, when valve rod 2 was moved upwards up to the extreme higher position, whorl side was taken over 5 and is communicated with flared tube 4.

On valve body 1, also be equipped with and fill fluorine mouth 6, when valve rod 2 is moved down into extreme lower position, fills fluorine mouth 6 and communicate with flared tube 4.

Valve seat 3 bottoms can also be provided with a mounting plates structure, and valve seat 3 is fixedlyed connected with cooling machine set by mounting plates structure.

Valve body 1 is connected with valve seat 3 and fixing seal, valve rod 2 is installed in the valve body 1, flared tube 4 is installed on the valve body 1, fills fluorine mouth 6, flared tube 4, fill fluorine mouth 6 and be welded to connect with valve body 1, whorl side is installed on the valve seat 3 takes over 5, whorl side is taken over 5 and is welded to connect with valve seat 3, valve seat 3 bottoms are provided with valve mounting hole 7, threaded 8 is installed in the valve mounting hole 7, and valve seat 3 is threaded with threaded 8, and valve seat 3 is fixedly installed on the refrigeration system unit by threaded 8.

Flared tube 4 is connected with the compressor porting of small-sized refrigerating unit, and whorl side is taken over 5 and is connected with the refrigeration system of small-sized refrigerating unit, fills fluorine mouth 6 and is used for to the additional freon refrigerant of refrigeration system or is used for instrument such as setting pressure table.
