Background technology
The composition of air-conditioning system mainly includes four major parts such as compressor, condenser, flow controller and evaporimeter, connects accessories such as valve in addition in addition.In existing system, adopt capillary to regulate the flow of cold-producing medium in the pipeline as restricting element mostly.Department's air-conditioning system is to avoid the defective of soldered elements, adopt to connect some elements in the valve connecting line, but flow controller be connected valve is still independent design and use in pipeline element.The components and parts that the system of this structure connects are many, and complex process, high material consumption, processing cost be than higher, and the flow controller vibration produces bigger noise during operation of air conditioner, the assembling procedure complexity, and restricting element is difficult to change, and has a strong impact on the performance of air-conditioning.
Summary of the invention
The invention provides a kind of compact conformation, restricting element does not take up space in addition, does not increase connection welding, and the reliability height, cost is low, noise is little, has the throttle junction valve of bidirectional throttle function.
The present invention is achieved in that
A kind of bidirectional throttle junction valve, comprise valve body, sliding cavity, integral type valve seat, valve pocket, described throttle junction valve is provided with integral type throttling valve core and slidingtype throttling valve core, and the integral type throttling valve core is provided with the first segment discharge orifice, and the slidingtype throttling valve core is provided with second throttle orifice.
Also can do further perfect by the following technical programs:
Described slidingtype throttling valve core front end is provided with rounded corner, and periphery is provided with the rib piece more than three.
The tube wall of described integral type throttling valve core and valve body is an one.
Described integral type valve seat is provided with the conical surface.
Throttle junction valve is provided with the screen modules that adopts collar fixing.
Described throttle junction valve valve body is provided with boss and cannelure, is provided with O type circle in the cannelure, and boss shoulder, O type circle closely contact with the sealing cone of stop valve connector front end.
Described throttle junction valve is threaded with stop valve, is connected with tube connector by nut, and throttle junction valve one end is provided with tube connector and forms the conical surface that is connected sealing.
The spool that the present invention will be provided with throttle orifice embeds or is integrated in the throttling function that connects realization air-conditioning system on the valve body, need not to connect separately flow controller, reduces consumption of materials, reduces cost; Be connected with stop valve by screw thread, boss closely contacts with the stop valve forward end seal conical surface, and O type circle and stop valve front end cone match sealing simultaneously forms firm, flexible double sealing structure, and it is more reliable to work; Throttle junction valve is threaded with stop valve, is connected with tube connector by nut, is convenient to loading and unloading, cleaning and the replacing of throttle junction valve, and maintenance and inspection air-conditioning are convenient, help reducing cost; Do not take up space in addition, help the air-conditioning miniaturization; Simplified the connection of air-conditioning system pipeline greatly, the noise that does not produce substantially during operation of air conditioner, the noise of generation also connected tube absorb, the big problem of noise when having solved existing operation of air conditioner.
