Abstract
The invention relates to the technical field of valves, in particular to a straight-through type stop valve for a refrigerating device. The straight-through type stop valve for the refrigerating device comprises a valve seat, a valve rod and a hand wheel. The valve seat is provided with a transverse pipe and an inclined pipe. The included angle between the transverse pipe and the inclined pipe is a non-right angle. One end of the transverse pipe is an inlet, and the other end of the transverse pipe is an outlet. A valve flap is arranged between the inlet and the outlet in a matched manner and connected with the valve rod. The valve rod penetrates the inclined pipe. The top end of the valve rod is connected with the hand wheel. A valve rod sleeve is arranged outside the valve rod and used for being in cooperation with connection of the valve rod and the valve seat. The straight-through type stop valve is reasonable in structural design, high in intensity, good in airtightness and especially suitable for the refrigerating device, and the service life of the straight-through type stop valve is prolonged greatly.
Description
Technical field
The present invention relates to valve technology field, especially a kind of refrigeration plant straight-through stop valve.
Background technique
Traditional straight-through stop valve structural design is simple, and its valve body often adopts cast structure, and intensity is low, and high voltage performance is poor; In addition, because valve stem casing generally adopts flange-type structure, seal with end face Placement, the time comparatively for a long time or pressure increase all can cause leakage, bring hidden danger to production safety.
Summary of the invention
The technical problem to be solved in the present invention is: based on the problems referred to above, the invention provides a kind of refrigeration plant straight-through stop valve.
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of refrigeration plant straight-through stop valve, comprise valve seat, valve rod and handwheel, described valve seat has horizontal pipeline and oblique pipeline, the angle of described horizontal pipeline and oblique pipeline is non-right angle, one end of described horizontal pipeline is import, the other end is outlet, flap is equipped with between import and outlet, flap connects valve rod, valve rod is through oblique pipeline, the top of valve rod connects handwheel, is provided with valve stem casing, to coordinate the connection of valve rod and valve seat outside described valve rod.
Further, the angle of described horizontal pipeline and oblique pipeline is 45 °.Arrange the angle that horizontal pipeline and oblique pipeline are 45 °, installation, maintenance is convenient.
The invention has the beneficial effects as follows: reasonable in design of the present invention, intensity is large, and good seal performance, working life extends greatly, is specially adapted to refrigeration plant.
Accompanying drawing explanation
Below in conjunction with accompanying drawing embodiment, the present invention is further described.
Fig. 1 is structural representation of the present invention.
In figure: 1. valve seat, 2. valve rod, 3. handwheel, 4. flap, 5. valve stem casing, 11. horizontal pipelines, 12. oblique pipelines, 11a. import, 11b. exports.
Embodiment
The invention will be further described in conjunction with specific embodiments now, and following examples are intended to the present invention instead of limitation of the invention further are described.
As shown in Figure 1, a kind of refrigeration plant straight-through stop valve, comprise valve seat 1, valve rod 2 and handwheel 3, valve seat 1 has horizontal pipeline 11 and oblique pipeline 12, the angle of horizontal pipeline 11 and oblique pipeline 12 is 45 °, one end of horizontal pipeline 11 is import 11a, the other end is outlet 11b, flap 4 is equipped with between import 11a and outlet 11b, flap 4 connects valve rod 2, and valve rod 2 is through oblique pipeline 12, and the top of valve rod 2 connects handwheel 3, valve stem casing 5 is provided with, to coordinate the connection of valve rod 2 and valve seat 1 outside valve rod 2.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to right.
