Abstract
The invention relates to the technical field of valves and in particular to a straight-through type stop valve for industrial refrigeration. The straight-through type stop valve for industrial refrigeration comprises a valve seat, a valve deck, a valve rod and a bonnet. The valve seat is provided with a transverse pipe and an inclined pipe. One end of the transverse pipe is an inlet and the other end of the transverse pipe is an outlet. A protrusion protruding relative to the inner wall of the transverse pipe is arranged on the boundary of the inclined pipe and the transverse pipe. The valve rod is arranged in the inclined pipe. A valve flap is arranged at the bottom of the valve rod. The top end of the valve rod is connected with the bonnet. Multiple arc-shaped grooves recessed inwards are arranged on one side of the outer wall of the bonnet. A lifting lug is arranged at the bottom of the bonnet. The straight-through type stop valve for industrial refrigeration is reasonable in structural design, large in strength, good in sealing performance, capable of greatly prolonging service life and particularly suitable for the industrial refrigeration industry.
Description
Technical field
The present invention relates to valve technology field, especially a kind of industrial refrigeration straight-through stop valve.
Background technique
Straight-through stop valve, it relies on valve rod pressure, and valve clack sealing surface and sealing surface of seat are combined closely, and stops medium circulation.The features such as between sealing surface, frictional force is little, wear-resisting in opening-closing process, Lift is little, and manufacturing process performance is good, it is most popular a kind of valve in industrial department.This kind of valve applications is when industrial refrigeration industry, if valve stem top installs handwheel, likely handwheel can skid, so ordinary priority consideration valve emits, but the structure that valve emits is also reasonable in design, could facilitate rotation valve rod.
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 industrial refrigeration straight-through stop valve.
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of industrial refrigeration straight-through stop valve, comprise valve seat, valve gap, valve rod and valve to emit, described valve seat has transverse pipe and oblique pipe, one end of transverse pipe is import, the other end is outlet, described oblique pipe and transverse pipe intersection have the projection relative to transverse pipe inwall, in described oblique pipe, valve rod is installed, the bottom of valve rod is provided with flap, the top of valve rod is connected with valve and emits, described valve emits outer wall side to have some inside circular grooves, and valve emits bottom to be provided with hanger.
Further, described valve emits and is threaded with valve gap, and the top of both joints is provided with O RunddichtringO.Reasonable in design, intensity is large, good seal performance.
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 industrial refrigeration industry.
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.

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 industrial refrigeration straight-through stop valve, comprise valve seat 1, valve gap 2, valve rod 3 and valve and emit 4, valve seat 1 has transverse pipe 11 and oblique pipe 12, one end of transverse pipe 11 is import 11a, the other end is outlet 11b, oblique pipe 12 and transverse pipe 11 intersection have the projection 5 relative to transverse pipe 11 inwall, in oblique pipe 12, valve rod 3 is installed, the bottom of valve rod 3 is provided with flap 6, the top of valve rod 3 is connected with valve and emits 4, and valve emits 4 outer wall sides to have some inside circular grooves 41, and valve is provided with hanger 42 bottom emitting 4.
Further, valve emits 4 to be threaded with valve gap 2, and the top of both joints is provided with O RunddichtringO 7.
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.
