Abstract
It include valve body (1), upper press cover (2), lower top cover (3), core (4), pilum (5), connecting tube (8), valve rod (9), sealing ring (10), screw thread retainer ring (11) the utility model discloses a kind of screw thread straight-through valve.The screw thread retainer ring (11) resists chuck (81) and is fixedly connected with pipe (8) by forming cooperation with the screw thread on valve body (1) both ends outer ring.First screwed pipe (6) and the second screwed pipe (7) in the case where not rotary valve, are connected to valve body, facilitate attended operation by screw thread straight-through valve provided by the utility model by the design of connecting tube (8).
Description
Technical field
The utility model relates to ball valve field more particularly to a kind of screw thread straight-through valves.
Background technique
This seven kinds of valves of gate valve, shut-off valve, plunger valve, butterfly valve, plug valve, diaphragm valve and ball valve account for about valve total amount 80%
More than.Wherein ball valve is with fluid resistance is small, it is unrestricted to flow to, opening and closing is rapid and the low comprehensive performance of height is preferably excellent
Point.The valve seat of existing ball valve is generally used the manufacture of the high molecular synthetic materials such as rubber, nylon and polytetrafluoroethylene (PTFE), uses temperature
Lower than 200 DEG C, which limits the use scopes of ball valve.Made on the pipeline of many medium and high temperature media using high molecular material
The hidden danger of failure is had for valve seat.The comprehensive performance of ball valve is improved using metal hard sealing structure using temperature and uses the longevity
Life, is the needs of the systems such as chemical industry, petroleum, electric power, metallurgy, concentrated supply of heating in the city and long-distance transport pipes.
It, will be in the screw thread of the pipeline precession screw thread ball valve of continuous mounting ball valve in screw thread ball valve.Pipeline is not in some cases
Allow to rotate, this causes certain difficulty to the installation of screw thread ball valve.
Utility model content
The purpose of the utility model is to overcome the defects of the prior art, provide a kind of screw thread straight-through valve, the technology
Scheme is achieved in that
A kind of screw thread straight-through valve include valve body, upper press cover, lower top cover, core, pilum, connecting tube, valve rod, sealing ring,
Screw thread retainer ring.
Valve rod is fixed on valve body by the upper press cover by the first bolt group, and the valve rod and core are removably solid
Knot, the sealing ring are set to core and form sealing cooperation along valve body direction both ends and core.
The valve body both ends are separately connected the first screwed pipe and the second screwed pipe by connecting tube, and the connecting tube inner ring is set
There is the internal screw thread with the first screwed pipe and the cooperation of the second screwed pipe, end of the connecting tube far from core is chuck, the screw thread
Retainer ring resists chuck and is fixedly connected with pipe by forming cooperation with the screw thread on the outer ring of valve body both ends.
Screw thread straight-through valve provided by the utility model, screw thread retainer ring resist chuck and by on the outer ring of valve body both ends
Screw thread forms cooperation and is fixedly connected with pipe.By the design of connecting tube, in the case where not rotary valve, by the first screwed pipe and
Two screwed pipes are connected to valve body, facilitate attended operation.
Optionally, the valve body lower portion is equipped with pilum and supports core, and the lower top cover is fixed on by the second bolt group
Valve body lower portion, the lower top cover limitation pilum fall off.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawings and detailed description；
Fig. 1 is the utility model screw thread straight-through valve schematic diagram.
Appended drawing reference: top cover under 1- valve body, 2- upper press cover, the first bolt of 21- group, 3-, the second bolt of 31- group, 4- core,
5- pilum, the first screwed pipe of 6-, the second screwed pipe of 7-, 8- connecting tube, 81- chuck, 9- valve rod, 10- sealing ring, 11- screw thread card
Circle.
Specific embodiment
As shown in Figure 1, a kind of revealed screw thread straight-through valve of the utility model, including valve body 1, upper press cover 2, lower top cover
3, core 4, pilum 5, connecting tube 8, valve rod 9, sealing ring 10, screw thread retainer ring 11.
Valve rod 9 is fixed on valve body 1 by the upper press cover 2 by the first bolt group 21, and the valve rod 9 and core 4 are removable
The consolidation unloaded, the sealing ring 10 are set to core 4 and form sealing cooperation along 1 direction both ends of valve body and core 4.
1 both ends of valve body are separately connected the first screwed pipe 6 and the second screwed pipe 7, the connecting tube 8 by connecting tube 8
Inner ring is equipped with the internal screw thread cooperated with the first screwed pipe 6 and the second screwed pipe 7, and end of the connecting tube 8 far from core 4 is chuck
81, the screw thread retainer ring 11 resists chuck 81 and is fixedly connected with pipe 8 by forming cooperation with the screw thread on 1 both ends outer ring of valve body.
In specific implementation, 1 lower part of valve body is equipped with pilum 5 and supports core 4, and the lower top cover 3 passes through the second bolt
Group 31 is fixed on 1 lower part of valve body, and the lower top cover 3 limits falling off for pilum 5.
Embodiment is only one embodiment of the utility model, for those of ordinary skill in the art, is not being paid
Under the premise of creative labor, other embodiments can also be obtained with reference to the accompanying drawings, also within protection scope of the present invention.
