Abstract
A straight-through stop valve for cooling comprises a valve casing, a valve rod, a seal ring and a seal cover. An inlet passage and an outlet passage are communicated with each other through a cylindrical cavity arranged at the center of the valve casing, and the middle of the cavity of the valve casing is provided with a thread connected with a middle thread of the valve rod. When the valve rod rotates, the thread can drive the valve rod to move vertically, and the lower section of the cavity of the valve casing is provided with a circular step which can match with a conical head of the valve rod to open or close a center passage. The seal ring is pressed on the cylindrical upper section of the valve rod by the seal cover to prevent refrigerant leakage, an elongated circular base for fixing is arranged at the bottom of the valve casing, and the tail end of the valve rod is provided with a rectangular shank for fixation of a rotary handle. The conicity of the conical head at the top end of the valve rod is 30 degrees. The straight-through stop valve for cooling has the advantages that by rotation of the valve rod, opening and closing can be realized, refrigerant flow can be precisely controlled, turbulent flows and runner resistance are reduced, and energy can be saved by more than twice.
Description
Technical field
The utility model belongs to the air conditioner field, relates in particular to a kind of cooling straight-through stop valve that air conditioner uses, and is applicable to that with R407C, R410A etc. be the split-type air conditioner of refrigeration agent.
Background technique
Along with social progress, rapid economic development, people are more and more general to the application of air conditioner.Refrigeration agent in the air conditioner is in the circulation heat transfer process; The stop valve that will inevitably be applied to is connecting split-type air conditioner indoor set and outdoor unit; Through operating valve lever, internal path that can valve body, when maintenance as service valve; Be used for vacuumizing, adding refrigeration agent etc., also can be used in the systems such as other refrigeration cycle.
Stop valve is mainly used in defrost, flow direction control and the break-make control of refrigeration system.Its working principle is: clockwise rotate valve rod, valve cuts out, to cut off the circulation of interior media; Rotate counterclockwise valve rod, can make opening of valves, to open the circulation of interior media.Valve mainly is the effect of playing medium in adjusting, the controlling plumbing fixtures through the keying of valve, comprises the flow of regulating medium, pressure, flow direction etc.
The nose cone tapering of the stop valve valve stem tip of existing technology is an angle of 90 degrees usually, and the water conservancy diversion distance is short, is adequate as the effect of closing or opening; But can not accurately control refrigerant flow; Also because the water conservancy diversion distance is short, refrigeration agent can produce turbulent flow when getting into outlet conduit, increases flow passage resistance; The inventor has scrutinized best-of-breed functionality how to bring into play stop valve, causes this case to take place thus.
Summary of the invention
The purpose of the utility model is to provide a kind of cooling straight-through stop valve, except playing closing function, can also more accurately control the flow of refrigeration agent.
To achieve these goals, the technological scheme of the utility model is following:
A kind of cooling straight-through stop valve comprises valve casing, valve rod, seal ring, sealing cover; Valve casing central authorities are provided with cylindrical cavity, have been communicated with the passage of importing and exporting, and supply refrigeration agent to pass through; The stage casing that the middle part of valve casing cavity is provided with screw thread and valve rod is threaded, when valve rod rotates; Screw thread can order about valve rod and move up and down; Valve casing cavity hypomere is provided with the round platform rank, can cooperate the nose cone of valve rod to close or open the passage of central authorities, and can control the runner size of refrigeration agent; The valve casing top also is provided with screw thread and sealing cover is threaded, and is provided with seal ring below the sealing cover, is provided with flat gasket support seal ring below the seal ring, and valve rod was threaded below the chip that prevents seal ring stopped up; The valve casing bottom is provided with oval shape base and supplies fixing using; The valve rod tail end is provided with rectangle side's handle, supplies the fixing usefulness of rotatable handle; A kind of cooling straight-through stop valve is characterised in that: described its tapering of valve stem tip nose cone is that 20 degree are to 60 degree angles.Tapering is little, and then whenever the rotate a circle cross section of fluid channel that brought of valve rod changes also for a short time, helps accurate control.Tapering greatly then water conservancy diversion distance is short, and refrigeration agent changes when too fast at cross section of fluid channel, can produce turbulent flow, increases circulating resistance; But tapering is too small, and then the valve casing cavity must extend, and has improved manufacture difficulty and manufacture cost, is 30 degree so the present invention is provided with best tapering.
As a kind of optimized project, said seal ring can be by multilayer build-up.
The invention has the beneficial effects as follows: the simple improvement brought tangible increased functionality, and the valve rod rotation is closed except plaing, the unlatching effect, can also accurately control the flow size of refrigeration agent, reduces turbulent flow, and the minimizing flow passage resistance force of waterproof is energy-conservation more than one times.

Embodiment
In order to make technological scheme of the present invention, operating feature clearer, with embodiment the utility model is done further elaboration in detail through accompanying drawing below.
Embodiment
A kind of cooling straight-through stop valve structure such as Fig. 1 are to shown in Figure 4.Referring to Fig. 4, valve rod 1 is cylindrical, and the top is nose cone 1-2, and the tapering of present embodiment is 30 degree angles, and the stage casing is provided with that the screw thread of screw thread and valve casing 2 middle cavities of protrusion is adaptive, and tail end has rectangle square toes 1-1, supplies that rotatable handle is fixing to be used.
Referring to Fig. 3, be provided with pipe for flowing of refrigerant road import 2-1 and outlet 2-2 on the cylindrical of valve casing 2, the channel connection between wherein the cavity of valve casing central authorities; The terminal joint of cavity and import 2-1 is provided with step 2-3, and its diameter and valve rod nose cone 1-2 are adaptive, and the cavity stage casing is provided with screw thread; Be threaded with valve rod 1 stage casing, the energy of rotation actuate valve stem 1 of valve rod 1 moves up and down, when valve rod 1 moves down; When nose cone 1-2 compressed step 2-3, coolant channel was closed; On valve rod 1, move, when nose cone 1-2 left step 2-3, coolant channel was opened, and it is far away that nose cone 1-2 leaves step 2-3, and then refrigerant flow is big more, and the rotation revolution of control valve rod 1 just can accurately be controlled the flow of refrigeration agent.Column part round valve rod 1 top is provided with seal ring 4 and flat gasket 5; Be tightened in 2 last times of valve casing to sealing cover 3, the three range upon range of seal rings that close 4 of extruding prevent that refrigeration agent is toward the air gap leakage above the valve casing 2.
