Abstract
It the utility model is related to a kind of stop valve with sampler,Including valve body,Sampler mainly is set in valve body middle chamber outer wall,The sampler is made up of sampling adapter and needle valve,Needle-like valve body is set on the boss of valve body middle chamber side wall,The needle valve body cavity is connected by thief hole with valve body middle chamber,Conical valve seat sealing surface is being set with the thief hole port of needle valve body cavity junction,Sampling adapter sealing is fixed on the valve body boss immediately below needle valve body cavity,Needle valve bonnet is connected on needle-like valve body,The needle valve bonnet uses nut connector,The nut connector one end is sealedly and fixedly connected by the internal thread of external screw thread and needle valve body cavity wall,Stuffing seal is installed between nut connector other end endoporus and valve rod periphery,Valve rod one end is formed with the conical surface to be cooperated with conical valve seat sealing surface,The other end is fixedly connected with handwheel.Separately installed sampling valve is not needed, there is the advantages such as sampling is easy, installation and operation expense is low.
Description
Technical field
The utility model belongs to valve field, more particularly to a kind of stop valve.
Background technology
When needing to be sampled analysis to the medium for flowing through pipeline, generally require to sample to install on branch pipe in pipeline one to take
Sample valve.Because sampling valve is arranged on sampling branch pipe, one section of deposition sample is always stayed in by-pass line and sampling valve front end.For viscosity compared with
Big medium, when by-pass line temperature is relatively low, easily there is medium and condense phenomenon, cause deposition sample to be not easy to release or sample tired
It is difficult.Moreover, installing sampling valve on special sampling branch pipe, equipment installation and operation expense is added.
The content of the invention
The purpose of this utility model is the shortcomings that presence for prior art, there is provided one kind sampling is easy, installation and operation
The low stop valve with sampler of expense.
The technical solution of the utility model includes valve body, mainly sets sampler, the sampling in valve body middle chamber outer wall
Device is made up of sampling adapter and needle valve, and needle-like valve body, the needle-like valve body are set on the boss of valve body middle chamber side wall
Inner chamber is connected by thief hole with valve body middle chamber, and conical valve seat is being set with the thief hole port of needle valve body cavity junction
Sealing surface, sampling adapter sealing are fixed on the valve body boss immediately below needle valve body cavity, and pin is connected on needle-like valve body
Type valve bonnet, the needle valve bonnet use nut connector, and the nut connector one end passes through external screw thread and needle valve body cavity wall
Internal thread be sealedly and fixedly connected, nut connector endoporus and valve rod periphery are dynamic to be coordinated, nut connector other end endoporus and valve rod
Stuffing seal is installed, valve rod one end is formed with the conical surface to be cooperated with conical valve seat sealing surface, the other end between periphery
It is fixedly connected with handwheel.
In above technical scheme, thief hole is located at needle valve body cavity side and is higher than valve body middle chamber side.
The utility model has the advantages that sampler is set in valve body middle chamber outer wall, it is not necessary to separately installed sampling valve, take
Sample is easy, installation and operation expense is low.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Stop valve with sampler as shown in Figure 1, including valve body 1, cavity outer wall sets sampler in valve body 1,
The sampler is formed by sampling adapter 2 and needle valve, and needle-like valve body, the pin are set on the boss of the lumen side wall of valve body 1
Type valve body inner chamber is connected by thief hole 10 with the lumen of valve body 1, at the end of thief hole 10 with needle valve body cavity junction
Mouth sets conical valve seat sealing surface, and the upper end sealing of sampling adapter 2 is fixed on the boss of valve body 1 immediately below needle valve body cavity
On, lower end connects sampling container, and needle valve bonnet 4 is connected on needle-like valve body, and the needle valve bonnet 4 uses nut connector, should
Nut connector one end is sealedly and fixedly connected by the internal thread of external screw thread and needle valve body cavity wall, nut connector endoporus and valve
The periphery of bar 3 is dynamic to be coordinated, and installs stuffing seal between nut connector other end endoporus and the periphery of valve rod 3, the filler is close
Seal apparatus is made up of filler 6, gland 7 and nut 8, and nut 8 is connected by internal thread with the external screw thread of nut joint, and passes through gland
Filler 6 is sealed compression by 7 to be arranged between valve rod 3 and nut joint, and the one end of valve rod 3 is formed with and conical valve seat sealing surface phase interworking
The conical surface of conjunction, the other end are fixedly connected with handwheel 9.
Thief hole 10 is located at needle valve body cavity side and is higher than the lumen side of valve body 1, and medium is prevented after sampling terminates
It is detained in thief hole 10 and condenses.Product sampling is convenient, easy, and installation and maintenance are simple, reduce installation, operating cost.
